dogeking涨了多少倍

春节联欢晚会上沈腾在小品《还不还》中多次提及“元宇宙里的DogKing”,同名DogeKing加密货币短线暴涨542倍,DOGEKING币的发行量为10,000,000亿枚。狗王大戏开唱,这一唱就唱到大年初七,一个星期的时间,狗王上涨幅度达到万倍,有人说3万,也有人说5万,可能是计算时最低点价格不同导致,但可操作的价格,最低点到最高点,大概是3200倍左右。【拓展资料】Doge King币中文全称是狗王币,是币安智能链上代币,为狗狗币的衍生币种,于2021年11月推出。该币流动性锁定一年,项目完全去中心化和社区驱动。Doge King是基于Elon Musk推广下的SHIB,DOGE,BABYDOGE后的新型通缩式货币令牌,我们将采取燃烧每笔交易的7%,5%分红给持有狗神币的人,2%用作销毁来加快货币通缩速度加快货币价值的增长速度,狗王币自开盘5分钟后即锁定lp流动池地址。公开信息显示,该币为币安智能链上代币,为狗狗币的衍生币种,于2021年11月推出。该币流动性锁定一年,项目完全去中心化和社区驱动,官网并未给出项目背后团队的名称和信息,也并未提供白皮书。虚拟币Dogeking此轮涨势凶猛,业内人士提醒投资者:“虚拟币Dogeking的暴涨,可以看作一种粉丝经济效应。但是,该币种实际应用价值较小,筹码过于集中,很容易出现市场操纵风险。目前的价格暴涨更多来自于营销炒作,后期不排除持币大户抛售离场的可能,因此风险较大。”不管大家是否要投资DOGEKING币,在投资前都应该做好充足的心理准备以及资金准备,不要盲目的跟风,别人说能赚钱就马上投资,不考虑其中的风险。很多时候我们都更加需要有自己的判断能力,做一个有主见的投资者。我们知道OGEKING币的暴涨其实就是一个偶然,而在币圈,像OGEKING币这样的币种其实还有很多,大多都逃不过辉煌之后的落寞,所以我们在投资的过程中也要小心防范其中的风险。

动物的资料

  1 The Felidae Family  Acinonyx jubatus (Cheetah)  Range and Habitat  Cheetahs range in the savanna regions of sub-Saharan Africa, and east of the rainforests in central Africa. A small population of approximately 200 cheetahs also occur in the Caspian Sea area in the countries of Iran, Turkey and Turkmenistan. Their range used to extend farther east to the Middle East and India, but have been eliminated and are thought to be extinct in these countries. The largest cheetah population exists in Namibia, with an estimated 2,000-3,000 cheetahs. However, even here their future is not secure, because Namibian farmers loose 10% of their livestock to cheetahs.  Physical Appearance  The cheetah is the most canid of all felines. They are adapted for running very fast. Males are slightly larger than the females. Cheetahs are shaped very differently from other felines. They have long, thin legs; a very lithe body (the same tapering shape as a greyhound); a very small and rounded head; and a very long thin tail that the cheetah uses as a balance when it runs. The cheetah has a yellowish-tawny-golden color coat with white underbody and face, and solid black spots all over its body, and a thick black tear stripe that runs from the inside corner of its eyes to its mouth. Their canine teeth are proportionately small for a cat, in order to make room for their enlarged nasal passages. Cheetahs claws don"t retract completely, and their feet are wider in relation to their body size. The soles of their feet are covered with rough scaly pads, in order to grip the ground while they run. All these characteristics help to make the cheetah the fastest land animal on the planet.  Unfortunately, though the cheetah"s body was designed for speed, it was not designed for endurance, it is a sprint runner. Cheetahs can only keep up their fastest pace (70 mph) for 400 yards before their body overheats and their muscles begin to tire and produce lactic acid from exhaustion. In fact, the cheetah"s body temperature can rise to over 105 degrees Fahrenheit, a fatal temperature. In order to help them get enough air to their huge lungs while they run, their nasal passage is very large and short. Their heart, lungs, bronchial tubes, and adrenal glands are larger, which also aid in the circulation of oxygen rich blood to the muscles.  The cheetah is poetry in motion when it runs. It has an extremely flexible spine, which it can flex and twist to increase its stride up to 20 feet in a single bound! Its hip, ankle, wrist and shoulder joints are also very flexible, as the cheetah sprints and dodges in numerous angles to catch its prey, and needs to be able to maneuver in a split second. The long thick tail acts as a rudder, and by flailing the tail around the cheetah can steer itself at very high speeds.  They are very easy to distinguish from the other large African spotted cat, the leopard, because they look so different. They have spots, whereas the leopard has rosettes. The cheetah is much smaller and thinner, and its legs are longer and very thin, where the leopard is much heavier and more muscular with proportionately shorter legs. The cheetah"s head and muzzle is more rounded and smaller than the leopards, and the leopard can jump up in trees and stalk on the ground, whereas the cheetah is restricted to staying on the ground.  2 The Felidae Family  King Cheetah  For years, strangely marked skins from cheetahs have come out of Africa, as well as reports of a strangely-marked giant cheetah. In 1975, in Kruger Park, South Africa, cryptozoologists Paul and Lena Bottriell observed and photographed a king cheetah. It was larger than a normal cheetah, and had strange blotchy markings on its body. They were able to obtain mounted specimens of these creatures to study.  At first, people felt that this new animal was a hybrid cheetah-leopard cross. Some king cheetahs were captured, and genetic tests done on them determined that this was false. The unusual coat pattern was caused by a recessive allele (gene), which was known as the "tabby gene", because the same gene in domestic cats controls the tabby markings on them. King cheetahs are the same species, and can interbreed with normal cheetahs and produce fertile young of both types. King cheetahs can breed with each other and produce fertile young of both sexes. And king cheetahs can be born to a normal cheetah pair. The king cheetah is not a subspecies of cheetah, but unusually marked indivuduals within a population. The king cheetah turns up in clumps within populations, and are widespread throughout Africa.  In 1981, in the DeWildt cheetah center in South Africa, a "king" cheetah was born. It was the first king cheetah born in captivity. They have the same body structures as a normal cheetah, but the markings are bigger and all the spots are connected in a blotchy pattern. This new mutation is giving biologists hope, as they believe that such mutations may mean that the cheetah is beginning to regain some genetic diversity. Such mutations rarely exist in the wild, but they have been seen.  Diet and Hunting Behavior  Cheetahs prefer to eat small ungulates: the Thompson"s gazelle, Grant"s gazelle, impala; and even occasionally rabbits. The cheetah eats as much of the prey it caught as it can, and does not return to its kills because it cannot defend them. The cheetah trades speed for strength. It hunts during the day so as not to come into contact with more nocturnal predators as lions and hyenas, who kill their cubs and eat them, and will kill the mother if they can catch her. The cheetah is the most successful solitary hunter, succeeding in up to 70% of their hunts. This is due to the fact that the cheetah is specialized, and by no means reflects on the cheetahs ability to catch a wide variety of prey. The only other hunter that is more successful than the cheetah is the African wild dog, which is the most successful cooperative hunter, catching up to 80% of their hunts.  Cheetahs hunt by sight, sometimes standing atop termite mounds to survey their surroundings. Once the desired prey is sighted, the cheetah silently stalks it, until it is within 50 - 100 yards of it. Then it explodes into action, and chases its prey across the savannah. The cheetah"s very flexible spine allows it the greatest running stride of all the big cats. It uses its long tail to balance it while it chases down its prey. And its extremely flexible hips allow it to make sharp turns. Once the prey is within reach, the cheetah uses its front paws to try and knock the legs out from under it. It then kills its prey by a choke hold from their small canines. During the hunt, they run so fast that their body temperature can reach up to 105 degrees farenheight, which can kill. So they can run very fast but don"t have very good endurance. Unfortunately, after all this effort, the exhausted and overheated cheetah usually cannot eat, because larger predators can easily take it away from the tired cheetah, who even if she wasn"t exhausted form the chase could not defend her food from them. Unlike most other carnivores, cheetahs never scavenge. They must eat fresh killed meat.  3 The Felidae Family  Reproduction and Life Cycle  Females reach sexual maturity at 2-3 years, and males at 3 years. Mating can take place year-round, but peaks during the rainy season (November to May). Like most cats, cheetahs are mating-induced ovulators, which means that they do not ovulate until after mating has occurred. In order for mating to take place, the female cheetah lays down and raises her rear end in the air, in a position called lordosis. The male cheetah"s penis, like all carnivores, has a bone called the baculum, which serves to stimulate the female cheetah"s vaginal wall. Also on the male cheetah"s penis are tiny backwards facing spines, which are found only in the cat family. They are believed to provide stimulation for ovulation. The act of copulation itself lasts only a minute or two at most. They may mate several times a day, and the oestrus period, or receptive time of the female, lasts up to fourteen days.  After a gestation period of 90 - 98 days, she gives birth to 1-3 cubs in a burrow made in thick grass. The cubs weigh 250 - 300 g (8.8 - 10.6 oz) when they are born. They stay in the burrow for 8 weeks. During this time, the mother moves her cubs constantly to avoid detection by predators. Their first teeth come in at 3-6 weeks of age, and are replaced by adult teeth by 8 months old. Until the cubs are 3 months old, they are covered with a long, fuzzy grey coat, which gradually falls out and their sleek, spotted coats fill in. This unusual coloration is thought to be camouflage for the cubs. Cubs are weaned at 4 months old, but continue to stay with their mother until they are about a year and a half old. During this time they are taught how to hunt. Infant mortality rate is 71% before 2 months, and 95% from two months to 1 year old. The high infant mortality rate is due to starvation, disease, and predation by lions, baboons and hyenas. Those that do survive take 1 1/2 years to mature, and in that time they stick with their mother to learn how to hunt. She will not breed until her cubs either all leave her or die. Cheetahs can live for up to 15 years in the wild.  Social Behavior  Cheetahs are generally solitary and diurnal (active in the daytime) by nature, but they are actually more social than most felids, except the lion. They are most active during the daytime to aviod conflict with the more nocturnal lion and hyena, which are the cheetah"s main enemies besides man. Females are usually found alone escept when she has young, and males live in coalitions of two to five members, trios being the most common. In areas of eastern and southern Africa, where other large predators have been eradicated, cheetahs are often seen in groups of 14 - 19 individuals. The males and females only get together to breed. After conception, the males leave the females and rejoin their coalitions. In these coalitions, the males live and hunt together, protecting one another from lions and hyenas, and providing food for everyone in the coalition, since it is easier to hunt in a group. Coalitions of cheetahs also have better success rates in establishing and maintaining a territory, and finding mates. Sometimes, a small family group consisting of males and females form. They hunt together as well, and are more successful than loners. The practice mutual grooming, which establishes bonds between members of the coalition. All cheetahs, whether they are the members of a coalition, or the lone cheetah, regularly mark off their home ranges with urine.  4 The Felidae Family  Cheetahs communicate with each other using a variety of sounds. Cheetahs don"t meow, but they do chirp and squeak. Mother cheetahs chirp to call their young. They also purr to show contentment and growl to show aggression. Cheetahs also communicate using body language, like other cats. Flattened ears and bared teeth mean aggression, and this is accentuated by white spots on the backs of black ears.  Threats  All cheetahs are endangered due to excessive hunting for their skins, and severely inbred because of a plague that swept across Africa in the last Ice age over 10,000 years ago, leaving only a few thousand cheetahs. The animals also have a low recovery rate, and were unable to mutate to produce a more genetically stable population. Those that survived and dodged the bullets of hunters were responsible for perpetuation of the species. Because there was such a small gene pool left, all African cheetahs today are descended from these few hundred cheetahs, so most are related. This can be proven by comparing coat patterns. All marked animals (those with spots, rosettes, or stripes) have their own unique patterns. Several cheetahs have shown similar, if not near identical, coat patterns; even those that are several thousands of miles apart. Biologists have also noticed that skin grafts between unrelated cheetahs in zoos take, instead of being rejected as they normally would. Thus, the world of the cheetah looks very dim, as no new genetic material can be introduced. Cheetahs have a sperm count that is 90% lower than a tiger or lion, and on top of that, 75% of the sperm are abnormal, having multiple tails, no tail, multiple heads, and even no heads. Captive breeding programs have not been successful, as cheetahs will not readily breed in captivity, and unfortunately, the offspring produced usually die.  Cheetahs are also threatened by lions, who will kill adult cheetahs if they can catch them, and kill their cubs when they find them hidden in the grass. Lions and hyenas also steal the cheetah"s kills, and since the cheetah is smaller, weaker, and cannot rick any physical damage, must relinquish its hard-earned kill.

(He died a dog"s death.)他死得很惨。3、He led a dog"s life. 他过着贫困的生活。4、This country is going to the dogs. 这个国家要垮台了。cat1、A cat may look at a king. [谚]猫也可以看国王。(指小人物也应该有些权利)2、There is nothing for it but to wait and see how the cat jumps. 眼前只有静待,看看事情如何转变。3、Has the cat got your tongue? 你为什么不吭声?(猫把你的舌头叼去了吗?)1 英语中的Cat译句:He is one of the literary fat cats. 错译:他简直是只大肥猫。也许是加菲猫动画片的流行会一些人译出这样的句子来,“大肥猫”是什么形象?其实fat cat是很早就有的一个俚语,意思是“有权有势的人”、“大亨”,所以原句的意思是:他是文学界的显赫人物。 英语中关于cat的习语很多,但是比作人时,一般给人的联想都不太好,也许是因为cat常和巫婆在一起,迷信认为遇到black cat是不吉利的征兆。说一个人(as) sick as a cat是说该人“病得厉害”,尤其指“恶心想吐”;一个(as) weak as a cat的人“身体非常虚弱”;cat in the pan则是“叛徒”。 英语中常用cat指恶意伤人、包藏祸心的女人,把脾气很坏的老太婆称之为old cat。由cat加上后缀的catty指“爱搬弄是非的人”,而cattish的意思是“狡猾的”。表示反对或嘲笑的嘘声被称为cat call。   英语文化中认为猫有九命(A cat has nine lives),生命力特别强;谚语A cat may look at a king的意思是“地位再低微的人也有自己的权利”。有些习语很形象,如:like a cat on hot bricks类似于汉语的“热锅上的蚂蚁”;let the cat out of the bag是“露出马脚”。   猫和老鼠的关系几乎所有文化都类似。英语中的When the cat"s away the mice will play.很有点“山中无老虎,猴子称大王”之意。动词短语play cat and mouse with someone是像猫抓住老鼠时不马上吃掉,而是捉住又放掉,然后又捉住那样折腾玩弄。至于英语习语中体现的猫和豿的关系也好理解,一般不会和睦相处,live a cat and dog life是“整天吵架不和”。   大家都知道It rains cats and dogs.是“大雨倾盆”的意思,但是这一说法的来源至今仍有不同意见,一说源自古代斯堪的那维亚神话:雨中巫婆骑着猫通过,而雨神乘的是一条豿。还有一个说法:古代街道排水设施太差,一下大雨,许多猫和豿都被淹死,雨水流走后,街上满是猫和豿的尸体。第三个说法是该成语来自希腊文的catadupe,意为“瀑布”,下瓢泼大雨时犹如瀑布,后来慢慢演变成了rain cats and dogs。

The Red Dog by Howard Maier的故事主要内容

One manu2019s best friend and choice only he could make.This is the story of a dog named Spook. From his nose to the point of his tail, he was the king as a king, he ruled me with love.When I was called into the army, I had no closed friend to take care of my dog ,for a long time I thought about what I should do with him .At last I put Spook in the car ,we went to a little valley where I used to stay in the summers ,the man who owned the small-town store was an old friend ,we had often gone hunting together. Would he take Spook? Would he hunt with him ? and ,most of all. would he love him?Yes, the man said .he would take him and hunt with him and take care for him ,but he said nothing of love ,for though people may write this word,they almost never use it, I watched him as he patted the dogu2019s head,the hand was gentle,Spooku2019s tail moved,but his eyes were looking at my face.Without a word ,I got into my car and went away .After I went into the army,I wrote to my friend ,asking about Spook,there was no answer ,each place I was went to after that was farther away,from each place I wrote a letter .no answer ever came. I began to write to other friends in the town, asking about my dog,some of them answerd,but no one told about the dog,Spook must have died,I thought ,I gave up asking ,and tried not to think about the dog.Four years went by,I finished my time in the army,I had a wife now,and we lived in the city,when summer came, we wanted to go to the town where I had left Spook,as we put the bags in the car,laurette,my wife,asked,”what if we see your Spook?”“He died,”I said,After a day in the car,.we came to the small town,I headed for the store,I left laurette in the car and went inside,my friend acted as though we had talked only a day or two before ,he acted as if there had never been a dog, I couldnu2019t stand it any longer .”what happened to Spook?” I asked,“why ,”said my friend, ”nothing happened to him,he is as well as you or I ,I saw him only the other day,”In surprise I asked,”what do you mean,you saw him?donu2019t you have him anymore?”“ I was called into the army too,”he said ,”so I gave Spook to a man who lived near here.”“who is he ?”I asked.“oh ,Spooku2019s not there now,he lived in five or six places after that .lives up with some people name crocker now,but we all see him,he visits around,heu2019s valley dog now.”“a valley dog?”“on his own,goes here and there,heu2019s in fine shape.in the fall a man goes out and there Spook is ,ready to go hunting ." there was nothing to say ,i could tell he thought the life of a valley dog was the best life any dog could have.i went back to the car without saying a word. my wife was quiet for a time,then he said,"Spooku2019s alive ,isnu2019t he ?”I nodded my head.“will you try to see him?”“sure,” I said .”why not?”“it would only hurt you ,and him,too,” lautette said .”donu2019t try to find him.”“do you think he could remember me u2013after all this time ?”We didnu2019t talk about it again.Time went by,and we went swimming and fishing ,but we never talked about the dog.Then one day I saw Spook. I was going up the side of the valley,I stopped to the rest on a rock looking over a field. a boy around twelve years old came out of the trees,then Spook ran out in front of the boy,with the sun shining on his coat,I knew him at once.The boy was walking across the field, but Spook ,as always,raced far in front of him,then back again ,and all the time the sun was shining on his beautiful red coat,I had never seen Spook looking so well or so beautiful, it took them about three minutes to cross the field .,then they went into the trees.When I went back to laurette ,I told her about it,the next time I saw Spook ,laurette was with me ,it was late afternoon ,a heavy rain was failing, we were having dinner on the covered porch of the town restaurant , up the street came a dog—head down ,tail down,he looked as and as only a dog can look when itu2019s wet.As the dog came into the light ,I said ,”that looks like Spook.”The dog stooped,and his head came up,it was Spook.He walked across the porch and came up to my side, he stood there,with water drooping off him coat, and looked up into my face for a minute ,then without a sound or a wag of his tail,he lay down at my feet.he dropped his head in his paws but never closed his eyes, he watched every move I made ,just the way he used tou3002When we walked out,Spook followed us ,when I opened the door of the car,he was the first in,he jumped to his place in the back corner and put his head next to the windowu3002“what are you going to do ?”my life asked.“what can I do on a night like this?”I said.“letu2019s go home,then,”she said.We took Spook to our house, the fire dried out his coat,he lay on the floor between laurette and me,facing me.At about ten,he came over to my chair,placed a paw on my leg ,and looked at me.“what does he want?”laurette asked.“out,”I said. I got up and opened the door for him, the rain had stopped and the moon was up.looking out into the dark.i said,”well ,thatu2019s that,I guess,he will to home now.” And for a minute I wished I had petted him or talked to him in the old way.After a time ,two quick barks sounded outside the door,I jumped from my chair,not knowing what to do.“well ,go on.”laurette said,”let him in.”When I went to bed,Spook took his place on the floor beside me and went to sleep.“this is why I didnu2019t want you to see him again.”laurette said.“but he was only two years old when I left him!after four years,who would have thought he would know me this way?”“donu2019t think of that.”said laurette .” think of Spook . think how beautiful and fit he is ,and remember that he has a good life for a dog,what kind of life would he have in the city? Both of us work,what would he have? A walk in the morning and again in the night? Never any grass or sun ,never to run free,you donu2019t want to take him back to that ,do you ?”“but lu2019m not doing anything !”I said ,”I havenu2019t even petted him .Spook is doing it all himself ,”“ you are the one who has to say .”“all right ,”I said .”he goes back to the crockers tomorrow,”We started out the next day,it was boiling hot,.turning off the road,we came up to the house,when I let Spook out of the car,he was making a crying sound ,noting in the world could have made me look into his eyes.The boy I had seen in the field that other morning answered the door,he looked surprised to see me with thedog,and all the time I talked to him,Spook kept pulling break my hold on him.the boy understood what had happened,he held Spook.and I got back in the car and went away.In a minute I saw him in the mirror ,he was racing after the car ,”the boy let him go!”I cried.I kept looking back .Spook was running and running ,and I knew he would never give up.Laurette cried out ,”do you want to kill him?stop the car!please!”Pulling off the road, I got out of the car and waited,Spook came up and dropped at my feet,laurette was crying.“Spook ,poor Spook ,”she kept saying,”we can take him with us. It will be all right .you can walk him in the morning before you go to work , Iu2019will come home at lunchtime and walk him then, we can work it out.”But I put Spook in the back of the car and headed for the crocker place. Laurette put a hand on my arm.“no,dear,”I said to her ,”last night you were talking with your head,now youu2019re talking with your heart , the head talk is betteru3002”This time I told the boy to put Spook in the house, when we drove away, I drove very fast,All this took place more than three years ago. But even now,after all this time , I have a terrible dream three or four times each year.The dream is aways the same ,I am ne ,in the car,and the same time I am Spook . I run and run, and the car never stops. The hard road hits my paws ,and the hot sun shines down on me ,and I keep saying over and over,”he doesnu2019t want me ,he doesnu2019t want me.”Then I feel a sadness so great that I cannot bear it ,at this point I wake up, and I get out of bed,I have never told lautette about the dream .I stand looking out of the windows,the streets are empty ,the dark ,cold houses,crowd them in ,there are no trees ,and that helps, I make myself think of Spook as I saw him that day in the green field, I see him running free,with the soft grass under his feet and the sun shining on his red coat, that helps,too.I go back to bed and to sleep,but even now,after writing it all down ,I donu2019t know if the decision I made for Spook was right or wrong.

关于细胞的资料。

分类: 烦恼 >> 情感情绪 问题描述: 我们的老师真烦啊~我不要网址,要答案。谢谢了~ 解析: 内分泌系统(endocrine system)是机体的重要调节系统,它与神经系统相辅相成,共同调节机体的生长发育和各种代谢,维持内环境的稳定,并影响行为和控制生殖等。内分泌系统由内分泌腺和分布于其它器官的内分泌细胞组成。内分泌细胞的分泌物称激素(hormone)。大多数内分泌细胞分泌的激素通过血液循环作用于远处的特定细胞,少部分内分泌细胞的分泌物可直接作用于邻近的细胞,称此为旁分泌(paracrine)。内分泌腺的结构特点是:腺细胞排列成索状、团状或围成泡状,不具排送分泌物的导管,毛细血管丰富。 内分泌细胞分泌的激素,按其化学性质分为含氮激素(包括氨基酸衍生物、胺类、肽类和蛋白质类激素)和类固醇激素两大类。分泌含氨激素细胞的超微结构特点是,胞质内含有与合成激素有关的粗面内质网和高尔基复合体,以及有膜包被的分泌颗粒等。分泌类固醇激素细胞的超微结构特点是,胞质内含有与合成类固醇激素有关的丰富的滑面内质网,但不形成分泌颗粒;线粒体较多,其嵴多呈管状;胞质内还有较多的脂滴,其中的胆固醇等为合成激素的原料。 每种激素作用于一定器官或器官内的某类细胞,称为激素的靶器官(target an)或靶细胞(target cell)。靶细胞具有与相应激素相结合的受体,受体与相应激素结合后产生效应。含氮激素受 *** 于靶细胞的质膜上,而类固醇激素受体一般位于靶细胞的胞质内。本章仅叙及甲状腺、甲状旁腺、肾上腺、垂体和松果体等内分泌腺,并简介弥散的神经内分泌系统。存在于其它器官内的内分泌细胞,如胰岛、卵泡、黄体、睾丸间质细胞、胃肠内分泌细胞等,分别在有关章节内叙述。< 一、甲状腺 甲状腺分左右两叶,中间以峡部相连。成人甲状腺平均重约25g,女性的甲状腺略重,并在月经期与妊娠期略增大。甲状腺表面包有薄层结缔组织被膜。结缔组织伸入腺实质,将其分成许多大小不等的小叶,每个小叶内含有20~40个甲状腺滤泡和许多滤泡旁细胞(图11-1) 图11-1 甲状腺 (一)滤泡 滤泡(follicle)大小不等,直径0.02~0.9mm,呈圆形、椭圆形或不规则形。滤泡由单层立方的滤泡上皮细胞(follicular epithelial cell)围成,滤泡腔内充满透明的胶质(colloid)。滤泡上皮细胞因功能状态而有形态变化。在功能活跃时,细胞增高呈低柱状,腔内胶质减少;反之,细胞变矮呈扁平状,腔内胶质增多。胶质是滤泡上皮细胞的分泌物,在切片上呈均质状,嗜酸性,它是一种糖蛋白,称甲状腺球蛋白。胶质的边缘常存在不着色的空泡,有人认为是滤泡上皮细胞吞饮胶质滴所致(图11-1)。 电镜下,滤泡上皮细胞游离面有微绒毛,胞质内有较发达的粗面内质网和较多的线粒体,溶酶体散在于胞质内,高尔基复合 *** 于核上区。细胞顶部胞质内有电子密度中等、体积较小的分泌颗粒(直径150~200nm),还有从滤泡摄入的低电子密度的胶质小泡(直径约1μm)。滤泡上皮基底面有完整的基板,邻近的结缔组织内富含有孔毛细血管和毛细淋巴管(图11-2) 图11-2 甲状腺滤泡上皮细胞(Fc)和滤泡旁细胞(Pc)超微结构及激素合成与分泌模式图 G 分泌颗粒 Cv胶质小泡 Ly溶酶体 甲状腺滤泡上皮细胞合成和分泌甲状腺激素(thyroid hormone)。甲状腺激素的形成经过合成、贮存、碘化、重吸收、分解和释放等过程。滤泡上皮细胞从血中摄取氨基酸,在粗面内质网合成甲状腺球蛋白的前体,继而在高尔基复合体加糖并浓缩形成分泌颗粒,再以胞吐方式排放到滤泡腔内贮存。滤泡上皮细胞能从血中摄取I-,它在过氧化物酶的作用下活化,再进入泡腔与甲状腺球蛋白结合成碘化的甲状腺球蛋白。滤泡上皮细胞在腺垂体分泌的促甲状腺激素的作用下,以胞吞方式将滤泡腔内的碘化甲状腺球蛋白再吸收入胞质,成为胶质小泡。胶质小泡与溶酶体融合,小泡内的甲状腺球蛋白被水解酶分解形成大量四碘甲腺原氨酸(T4,即甲状腺素thyroxine)和少量三碘甲腺原氨酸(T3)。T3和T4经细胞基底部释放入毛细血管内(图11-2)。在滤泡上皮细胞附近可见肾上腺素能神经末梢,故细胞的分泌活动也受神经调节。 T3和T4作用于机体的多种细胞,主要功能是促进机体的新陈代谢,提高神经兴奋性,促进生长发育,尤对婴幼儿的骨骼发育和中枢神经系统发育影响很大,小儿甲状腺机能低下,不仅身材矮小,而且脑发育障碍,导致呆小症。 (二)滤泡旁细胞 滤泡旁细胞(parafollicular cell)又称C细胞,位于滤泡之间和滤泡上皮细胞之间(图11-1)。细胞稍大,在HE染色切片中胞质着色略淡,银染法可见胞质内有嗜银颗粒。电镜下,位于滤泡上皮细胞之间的滤泡旁细胞基部附着于基板,顶部被邻近的滤泡上皮细胞覆盖。滤泡旁细胞质内有直径200nm的分泌颗粒,细胞以胞吐方式释放颗粒内的降钙素(图11-2)。降钙素(calcitonin)是一种多肽,能促进成骨细胞的活动,使骨盐沉着于类骨质,并抑制胃肠道和肾小管吸收Ca2+,而使血钙下降。< 二、甲状旁腺 甲状旁腺一般有上下两对,位于甲状腺左右叶的背面。成人甲状旁腺呈棕黄色的扁椭圆形,总重约120mg。腺表面包有薄层结组织被膜, 腺细胞排列成索团状,其间富含有孔毛细血管及少量结缔组织,还可见散在脂肪细胞,并随年龄增长而增多。腺细胞有主细胞和嗜酸性细胞两种(图11-3)。 图11-3 甲状旁腺 (一)主细胞 主细胞(chief cell)呈圆形或多边形,核圆,位于细胞中央,HE染色切片中胞质着色浅。电镜下,胞质内含粗面内质网、高尔基复合体和直径200~400nm的分泌颗粒,还有一些糖原和脂滴(图11-4)。细胞分泌颗粒内的甲状旁腺激素(parathyroid hormone)以胞吐方式释放入毛细血管内。甲状旁腺激素是肽类激素,主要功能是作用于骨细胞和破骨细胞,使骨盐溶解,并能促进肠及肾小管吸收钙,从而使血钙升高。在甲状旁腺激素和降钙素的共同调节下,维持着血钙的稳定。 (二)嗜酸性细胞 从青春期前后开始,某些动物和人的甲状旁腺内出现嗜酸性细胞(oxyphil cell),并随年龄而增多,细胞常单个或成群存在于主细胞之间。嗜酸性细胞比主细胞大,核较小,染色较深,胞质内含密集的嗜酸性颗粒,故呈强嗜酸性。电镜下,嗜酸性颗粒乃是线粒体,其它细胞器均不达,糖原和脂滴也少,且无分泌颗粒(图11-4)。此细胞的机能意义不明。 图11-4 甲状旁腺主细胞及嗜酸性细胞超微结构模式图 三、肾上腺 肾上腺位于肾的上方,右侧肾上腺呈扁平三角形,左侧呈半月形。成人的每侧肾上腺重4~5g。肾上腺表面包以结缔组织被膜,少量结缔组织伴随血管和神经伸入腺实质内。肾上腺实质由周边的皮质和中央的髓质两部分构成,两者在发生、结构和功能上均不相同,皮质来自中胚层,髓质来自外胚层。 (一)皮质 皮质约占肾上腺体积的80%~90%,根据皮质细胞的形态结构和排列等特征,可将皮质分为三个带,即球状带、束状带和网状带(图11-5)。 1.球状带 球状带(zone glomerulosa)位于被膜下方,较薄,占皮质总体积的15%。细胞呈球状分布,细胞较小,呈矮柱状或 锥形,核小染色深,胞质较少,内含少量脂滴。细胞团之间为窦状毛细血管和少量结缔组织(图11-5)。球状带细胞分泌皮质激素(mineralocorticoid),如醛固酮(aldosterone),它能促进肾远曲小管和 *** 小管重吸收Na+及排出K+,同时 *** 胃粘膜、唾液腺和汗腺吸收Na+,使血Na+浓度升高,K+浓度降低,维持血容量。盐皮质激素的产生受肾素-血管紧张素系统的影响,肾球旁细胞分泌的肾素(renin)可使血浆中的血管紧张素原(angiotensinogen),变成血管紧张素(angiotensin),后者可 *** 球状带细胞分泌盐皮质激素。 2.束状带 束状带(zona fasciculata)是皮质中最厚的部分,占皮质总体积的78%。在人和大多数动物,束状带细胞比皮质其它两带的细胞大,细胞呈多边形,排列成单行或双行细胞索,索间为窦状毛细血管和少量结缔组织。细胞的胞核圆形,较大,着色浅。胞质内含有大量的脂滴,在常规切片标本中,因脂滴被溶解,故染色浅而呈空泡状(图11-5)。束状带细胞分泌糖皮质激素(glucocorticoid),主要为皮质醇(cortisol)和皮质酮(corticosterone),可促使蛋白质及脂肪分解并转变成糖(糖异生),还有降低免疫应答及抗炎症等作用。束状带细胞受腺垂体细胞分泌的促肾上腺皮质激素(ACTH)的调控。 3.网状带 网状带(zona reticularis)位于皮质的最内层,占皮质总体积的7%,细胞索相互吻合成网,网间为窦状毛细血管和少量结缔组织。网状带细胞较束状带细胞小,胞核也小,着色较深,胞质内含较多脂褐素和少量脂滴,因而染色较束状带深(图11-5)。网状带细胞主要分泌雄激素,也分泌少量糖皮质激素,故也受促肾上腺皮质激素的调节。另外,网状带和束状带可能还分泌少量雌激素。 图11-5 肾上腺 肾上腺皮质细胞分泌的激素均属类固醇,都具有分泌类固醇激素细胞的超微结构特点。如肾上腺皮质细胞。特别是束状带细胞胞质内含有丰富的滑面内质网和脂滴,线粒体嵴多呈小管状或小泡状(图11-6)。 图11-6 猴肾上腺皮质束状带细胞电镜像 ×14600 L脂滴,M线粒体 (白求恩医科大学尹昕、朱秀雄教授供图) (二)髓质 髓质主要由排列成索或团的髓质细胞组成,其间为窦状毛细血管和少量结缔组织。髓质细胞呈多边形,如用含铬盐的固定液固定标本,胞质内呈现出黄褐色的嗜铬颗粒,因而髓质细胞又称为嗜铬细胞(chromaffin cell)。另外,髓质内还有少量交感神经节细胞,胞体较大,散在分布于髓质内(图11-5)。 电镜下,髓质细胞最显著的特征是,胞质内含有许多电子密度高的膜被分泌颗粒,直径150~350nm 。根据颗粒内含物质的差别,髓质细胞分为两种。一种为肾上腺素细胞,颗粒内含肾上腺素(adrenaline),此种细胞数量多,约占人肾上腺髓质细胞的80%以上(图11-7)。另一种为去甲肾上腺素细胞,颗粒内含去甲肾上腺素(noradrenaline)。肾上腺素和去甲肾上腺素为儿茶酚胺类物质。此外,两种细胞的颗粒内尚含ATP及嗜铬颗粒蛋白,它们与肾上腺素或去甲肾上腺素组成复合物贮存在颗粒内。髓质细胞可与交感神经节前纤维形成突触,节前纤维末梢释放之酰胆碱作用髓质细胞,引起髓质细胞分泌颗粒释放肾上腺素或去甲肾上腺素入血。肾上腺素使心率加快、心脏和骨骼肌的血管扩张;去甲肾上腺素使血压增高,心脏、脑和骨骼肌内的血流加速。 图11-7 大鼠肾上腺髓质肾上腺素细胞 ×10000 (白求恩医科大学尹昕、朱秀雄教授供图) (三)肾上腺的血管分布 肾上腺动脉进入被膜后,分支形成动脉性血管丛,其中大部分分支进入皮质,形成窦状毛细血管网,并与髓质毛细血管通连。少数小动脉分支穿过皮质直接进入髓质,形成窦状毛细血管。髓质内的小静脉汇合成一条中央静脉,经肾上腺静脉出肾上腺(图11-8)。因而肾上腺的大部分血液是经过皮质到达髓质的,血液中含有皮质激素,其中的糖皮质激素可增强肾上腺素细胞内N-甲基移酶的活性,使去甲肾上腺素甲基化为肾上腺素。由此可见,肾上腺皮质对髓质细胞的激素生成有很大的影响。 图11-8 肾上腺的血管分布 四、垂 体 垂 *** 于蝶鞍垂体窝内,体积约0.5cm×1cm×1cm,重约0.5g.垂体由腺垂体和神经垂体两部份组成,表面包以结缔组织被膜。腺垂体来自胚胎口凹的外胚层上皮,神经垂体由间脑底部的神经外胚层向腹侧突出的神经垂体芽发育而成。神经垂体分为神经部和漏斗两部分,漏斗与下丘脑相连。腺垂体分为远侧部、中间部及结节部三部分。远侧部最大,中间部位于远侧部和神经部之间,结节部围在漏斗周围(图11-9)。远侧部又称前叶,神经部和中间 部合称后叶。 < 图11-9 垂 体(矢状切面) (一)腺垂体 1.远侧部 远侧部(pars distalis)的腺细胞排列成团索状,少数围成小滤泡,细胞间具有丰富的窦状毛细血管和少量结缔组织。在HE染色切片中,依据腺细胞着色的差异,可将其分为嗜色细胞和嫌色细胞两大类。嗜色细胞(chromophil cell)又分为嗜酸性细胞和嗜碱性细胞两种(图11-10)。应用电镜免疫细胞化学技术,可观察到各种腺细胞均具有分泌蛋白类激素细胞的结构特点,而各类腺细胞胞质内颗粒的形态结构、数量及所含激素的性质存在差异,可以此区分各种分泌不同激素的细胞,并以所分泌的激素来命名。 (1)嗜酸性细胞:数量较多,呈圆形或椭圆形,直径14~19mμ胞质内含嗜酸性颗粒,一般较嗜碱性细胞的颗粒大(图11-10)。嗜酸性细胞分两种:①生长激素细胞,(somatotroph,STH cell)数量较多,电镜下见胞质内含大量电子密度高的分泌颗粒,直径350-~400nm(图11-11)。此细胞合成和释放的生长激素(growth hormone ,GH;或somatotropin)能促进体内多种代谢过程,尤能 *** 骺软骨生长,使骨增长。在幼年时期,生长激素分泌不足可致垂体侏儒症,分泌过多引起巨人症,成人则发生肢端肥大症。②催乳激素细胞(mammotroph,prolactin cell),男女两性的垂体均有此种细胞,但在女性较多。在正常生理情况下,胞质内分泌颗粒的直径小于200nm;而在妊娠和哺乳期,分泌颗粒的直径可增大至600nm 以上,颗粒呈椭圆形或不规则形(图11-11),细胞数量也增多并增大。此细胞分泌的催乳激素(mammotropin或prolactin)能促进乳腺发育和乳汁分泌。 (2)嗜碱性细胞:数量较嗜酸性细胞少,呈椭圆形或多边形,直径15~25μm,胞质内含嗜碱性颗粒(图11-10)。颗粒内含糖蛋白类激素,PAS反应呈阳性,嗜碱性细胞分三种:①促甲状腺激素细胞(thyrotroph,TSH cell),呈多角形,颗粒较小,直径100~150nm(图11-11),分布在胞质边缘。此细胞分泌的促甲状腺激素(thyrotropin或thyroid stimulating hormone,TSH)能促进甲状腺激素的合成和释放。②促性腺激素细胞(gonadotroph),细胞大,呈圆形或椭圆形,胞质内颗粒大小中等,直径250~400nm(图11-11)。该细胞分泌卵泡 *** 素(follicle stimulating hormone,FSH)和黄体生成素(luteinizing hormone,LH)。应用电镜免疫细胞化学技术,发现上述两种激素共同存在于同一细胞的分泌颗粒内。卵泡 *** 素在女性促进卵泡的发育,在男性则 *** 生精小管的支持细胞合成雄激素结合蛋白,以促进 *** 的发生。黄体生成素在女性促进排卵和黄体形成,在男性则 *** 睾丸间质细胞分泌雄激素,故又称间质细胞 *** 素(interstitial cell stimulating hormone ,ICSH)③促肾上腺皮质激素细胞(corticotroph,ACTH cell),呈多角形,胞质内的分泌颗粒大,直径400~550nm(图11-11)。此细胞分泌促肾上腺皮质激素(adrenocorticotropin,ACTH)和促脂素(lipotropin或lipotrophic hormone,LPH)。前者促进肾上腺皮质分泌糖皮质激素,后者作用于脂肪细胞,使其产生脂肪酸。 图11-10 腺垂体远侧部及中间部 (3)嫌色细胞(chromophobe cell):细胞数量多,体积小,呈圆形或多角形,胞质少,着色浅,细胞界限不清楚(图11-10)。电镜下,部分嫌色细胞胞质内含少量分泌颗粒,因此认为这些细胞可能是脱颗粒的嗜色细胞,或是处于形成嗜色细胞的初期阶段。其余大多数嫌色细胞具有长的分支突起(图11-11),突起伸入腺细胞之间起支持作用。 图11-11 大鼠腺垂体远侧部腺细胞 电镜像 ×5000 S生长激素细胞,M催乳激素细胞 T促甲状腺激素细胞, G促性腺激素细胞 A促肾上腺皮质激素细胞,C嫌色细胞 2.中间部 人的中间部(pars intermedia)只占垂体的2%左右,是一个退化的部位,由嫌色细胞和嗜碱性细胞组成,这些细胞的功能尚不清楚。另外,还有一些由立方上皮细胞围成的大小不等的滤泡,泡腔内含有胶质(图11-10)。鱼类和两栖类中间部分能分泌黑素细胞 *** 素(melanocyte stimulating hormone,MSH),系吲哚胺类物质,可使皮肤黑素细胞的黑素颗粒向突起内扩散,体色变黑。 3.结节部 结节部(pars teberalis)包围着神经垂体的漏斗,在漏斗的前方较厚,后方较薄或缺如。此部含有很丰富的纵形毛细血管,腺细胞呈索状纵向排列于血管之间,细胞较小,主要是嫌色细胞,其间有少数嗜酸性和嗜碱性细胞。此处的嗜碱性细胞分泌促性腺激素(FSH和LH)。 4.腺垂体的血管分布 腺垂体主要由大脑基底动脉发出的垂体上动脉供应。垂体上动脉从结节部上端进入神经垂体的漏斗,在该处形成袢样的窦状毛细血管网,称第一级毛细血管网。这些毛细血管网下行到结节部汇集形成数条垂体门微静脉,它们下行进入远侧部,再度形成窦状毛细血管网,称第二级毛细血管网。垂体门微静脉及其两端的毛细血管网共同构成垂体门脉系统(hypophyseal portal system)。远侧部的毛细血管最后汇集成小静脉注入垂体周围的静脉窦(图11-12)。这是30年代确立的经典垂体血流模式“自上而下”的概念,阐明了下丘脑控制垂体功能的基本机制。此后又通过新技术的应用和研究,对垂体的血流模式提出了新见解,认为远侧部的血液可输入神经垂体的漏斗,然后经毛细血管回流入下丘脑;也可流入神经部,再逆向流入漏斗,然后再循环到远侧部或下丘脑,构成整个垂体血流在垂体内的循环流动。 5.下丘脑与腺垂体的关系 下丘脑神前区和结节区(弓状核等)的一些神经元具有内分泌功能,称为神经内分泌细胞,细胞的轴突伸至垂体漏斗。细胞合成的多种激素经轴突释放入漏斗处的第一级毛细血管网内,继而经垂体门微静脉输至远侧部的第二级毛细血管网。这些激素分别调节远侧部各种腺细胞的分泌活动(图11-12)。其中对腺细胞分泌起促进作用的激素,称释放激素(releasing hormone,RH)。对腺细胞起抑制作用起抑制作用的激素,则称为释放抑制激素(release inhibiting hormone,RIH)目前已知的释放激素有:生长激素释放激素(GRH)、催乳激素释放激素(PRH)、促甲状腺激素放激素(TRH)、促性腺激素释放激素(GnRH)、促肾上腺皮质激素释放激素(CRH)及黑素细胞 *** 素释放激素(MSRH)等。释放抑制激素有:生长激素释放抑制激素(或称生长抑素,SOM)、催乳激素释放抑制激素(PIH)和黑素细胞 *** 素释放抑制激素(MSIH)等。由此可见,下丘脑通过所产生的释放激素和释放抑制激素,经垂体门脉系统,调节腺垂体内各种细胞的分泌活动;因而,将此称为下丘脑腺垂体系。反之,腺垂体产生的各种激素又可通过垂体血液环流,到达下丘脑,反馈影响其功能活动。 图11-12 垂体的血管分布及其与下丘脑的关系 6.腺垂体的神经支配 传统认为,垂体前叶仅有少量自主神经纤维,支配前叶内血管的舒缩;而腺细胞的分泌活动则主要受下丘脑各种激素的调节,并无神经的直接支配。近几年来,国外学者(Friedman 和Payette)分别在大鼠、小鼠及蝙蝠垂体前叶发现5-羟色胺神经纤维;我国学者(鞠躬等)采用光镜及电镜免疫组织化学技术,也发现人、猴、狗、大鼠垂体前叶均有肽能神经纤维分布,纤维内含的肽类有P物质(SP)、降钙素基因相关肽(CGRP)、甘丙肽(GAL)、生长抑素(SOM)等,并发现含SP的神经纤维与各类腺细胞直接接触,电镜下发现,含SP和CGRP纤维与生长激素细胞和促肾上腺皮质激素细胞形成典型的突触(图11-13)。 图11-13 大鼠腺垂体远侧部免疫电镜像 ×60000 示P物质神经末梢(SP)与促肾上腺皮质细胞(A)形成突触(↑) (第四军医大学鞠躬教授供图) 前叶内肽能神经纤维的起源还不清楚,究竟是来自下丘脑或周围神经系统,还是两者兼有,尚未确定。前叶内肽能神经纤维的发现及其功能的研究,有可能修正目前对垂体前叶分泌功能调节的认识,即前叶腺细胞除接受体液调节外,还可能直接受神经的支配。 (二)神经垂体及其与下丘脑的关系 神经垂体与下丘脑直接相连,因此两者是结构和功能的统一体。神经垂体主要由无髓神经纤维和神经胶质细胞组成,并含有较丰富的窦状毛细血管和少量网状纤维。下丘脑前区的两个神经核团称神上核和室旁核,核团内含有大型神经内分泌细胞,其轴突经漏斗直抵神经部,是神经部无髓神经纤维的主要来源(图11-12)。 神上核和室旁核的大型神经内分泌细胞除具有一般神经元的结构外,胞体内还含有许多直径为100~200nm的分泌颗粒,分泌颗粒沿细胞的轴突运输到神经部,轴突沿途呈串珠状膨大,膨大部(称膨体)内可见分泌颗粒聚集(图11-12)。光镜下可见神经部内有大小不等的嗜酸性团块,称赫令体(Herring body)即为轴突内分泌颗粒大量聚集所成的结构(图11-14)。神经部内的胶质细胞又称垂体细胞(pituicyte),细胞的形状和大小不一。电镜下可见垂体细胞具有支持和营养神经纤维的作用。垂体细胞还可能分泌一些化学物质以调节神经纤维的活动的激素的释放。 图11-14 垂体神经部结构模式图 视上核和室旁核的大型神经内分泌细胞合成抗利尿素(antidiuretic hormone,ADH)和催产素(oxytocin)。抗利尿素的主要作用是促进肾远曲小管和 *** 管重吸收水,使尿量减少;抗利尿素分泌若超过生理剂量,可导致小动脉平滑肌收缩,血压升高,故又称加压素形成的分泌颗粒有加压素和催产素,分泌颗粒沿轴突运送到神经部储存,进而释放入窦状毛细管内(图11-12)。因此,下丘脑与神经垂体是一个整体,两者之间的神经纤维构成下丘脑神经垂体束。 神经部的血管主要来自左右颈内动脉发出的垂体下动脉,血管进入神经部分支成为窦状毛细管网。部分毛细血管血液经垂体下静脉汇入海绵窦(图11-12)。部分毛细血管血液逆向流入漏斗,然后从漏斗再循环到远侧部或下丘脑。 (三)下丘脑和腺垂体与其它内分泌腺的相互关系 在正常状态下,各类激素的分泌量是相对稳定的。内分泌腺活动的稳定性,除受神经系统的调节控制外,某些内分泌腺之间的相互协调也起重要作用,其中下丘脑和腺垂体与其它几种内分泌腺之间的相互调节尤为重要。下丘脑的各种神经内分泌细胞分泌的释放激素或释放抑制激素,调节腺垂体相应腺细胞的分泌活动,腺垂体分泌的各种激素又调节相应靶细胞的分泌和其它功能活动。另一方面,靶细胞的分泌物或某种物质(如血糖、血钙等)的浓度变化,反过来又可影响腺垂体和下丘脑的分泌活动,这种调节称为反馈。通过正、负反馈调节以维持机体内环境的相对稳定和正常生理活动。例如,下丘脑的神经内分泌细胞分泌促甲状腺激素释放激素,促进腺垂体远侧部的促甲状腺激素细胞分泌促甲状腺激素,后者又促进甲状腺滤泡上皮细胞合成和分泌甲状腺激素。当血液甲状腺激素达到一定水平时,则引起负反馈作用,抑制下丘脑或腺垂体相应激素的分泌,这样又使甲状腺的分泌功能和血液中的甲状腺激素水平下降。当激素下降到一定水平时,再以正反馈调节使激素分泌增多(图11-15)。 11-15 下丘脑与垂体的激素对靶器官作用示意图 五、松果体 松果体又称脑上腺,呈扁圆锥形,以细柄连于第三脑室顶。松果体表面包以软膜,软膜结缔组织伴随血管伸入腺实质,将实质分为许多小叶,小叶内主要由松果体细胞、神经胶质细胞和无髓神经纤维等组成。 松果体细胞(pinealocyte)与神经内分泌细胞类似,在HE染色片中,胞体呈圆形或不规则形,核大,胞质少,弱嗜碱性。在银染色切片中,可见细胞具有突起,短而细的突起终止在邻近细胞之间,长而粗的突起多终止在血管周间隙(图11-16)。电镜下,松果体细胞内线粒体和游离核糖体较多,高尔基复合体较发达,可见少量滑面内质网和粗面内质网;胞质内还常见小圆形分泌颗粒,颗粒内含有细胞合成的褪黑激素(melatonin)。此外,胞质尚有一种称为突触带(synaptic ribbon)的结构,它由电子致密的杆状体的周围的许多小泡组成(图11-17)。在低等动物,松果体作为光感受器,松果体细胞的突触带为突触前成分的组成部分;但在哺乳动物,则见突触小带分布于相邻松果体细胞相互接触处,或松果体细胞与细胞外间隙或脑脊液相接触的部位。因此,哺乳动物突触带系突触前成分的提法不能成立。突触带可能与化学介质的运输和释放有关。 图11-16 银染法示松果体细胞模式图 图11-17 松果体超微结构模式图 神经胶质细胞位于松果体细胞之间,胞体较小,核小着色深。在成人的松果体内常见脑砂(brain sand),它是松果体细胞分泌物经钙化而成的同心圆结构,其意义不明。 松果体细胞分泌褪黑激素。在两栖类,褪黑激素的作用与黑素细胞 *** 素相拮抗,可使皮肤褪色。在哺乳动物,褪黑激素具有抑制生殖腺发育的效应,主要是通过抑制垂体促性腺激素而间接影响生殖腺的活动。近年研究报道,褪黑激素的合成分泌不足,可能会引起睡眠紊乱、情感障碍、肿瘤发生等。经予外源性褪黑激素,可见其具有抗紧张、抗高血压、抗衰老、抗肿瘤、增强免疫力和促进睡眠等效应。白天日照时,松果体几乎停止分泌活动,至夜间才分泌褪黑激素。故生物体能依外界的日照变化,有节奏地控制松果体的功能活动。哺乳动物松果体昼夜节奏性变化是受视交叉背侧的视交叉上核的调节;反之,松果体也影响神交叉上核的昼夜节奏变化。 松果体除接受颈上交感神经节的神经支配外,还可能受其它来源的神经支配。 六、弥散神经内分泌系统 除上述内分泌腺外,机体许多其他器官还存在大量散在的内分泌细胞,这些细胞分泌的多种激素样物质在调节机体生理活动中起十分重

吃pocky是什么意思啊?

吃pocket是和自己的爱人分别从两头开始吃一根零食的意思。Pocky是日本的一种条状零食。一直一起吃的话,总会亲到一起的。有一种在聚会或者说分享式的吃法,一个人叼着pocky的一端,请自己的恋人或者朋友从另一端开始,双方比谁先吃u200cu200cu200cu200cu200cu200cu200cu200cu200cu200cu200cu200cu200c完吃到更多,但大部分情况下会直接亲到一起,所以其实是极其暧昧的游戏。梗分类1、讽刺类如“inm梗”,是对某些引人不满的事件套用相关素材进行剪辑制作从而进行讽刺,此类“梗”包含贬义暗示,甚至带有侮辱性质,不适合所有社交场合运用,却常常被一些青年网民因叛逆心理等因素而滥用,类似的有“六学”之类。2、诙谐类这些“梗”作为谈资笑料,对于某一有趣事物引发相关讨论而形成“梗”。如竹鼠“梗”,便是源于搞笑视频片段,大多数“梗”虽都有轻松娱乐意味,但此类型较其他“梗”相比,暗示性更少,娱乐性更多,更容易被青年网民理解与接受。

药物的发展史

l9世纪末,化学工业的兴起,Ehrlich化学治疗概念的建立, 为20世纪初化学药物的合成和进展奠定了基础。例如早期的含锑、砷的有机药物用于治疗锥虫病、阿米巴病和梅毒等。在此基础上发展用于治疗疟疾和寄生虫病的化学药物。 20世纪30年代中期发现百浪多息和磺胺后,合成了一系列磺胺类药物。1940年青霉素疗效得到肯定,β内酰胺类抗生素得到飞速发展。化学治疗的范围日益扩大,已不根于细茵感染的疾病。随着1940年woods和FildeS抗代谢学说的建立,不仅阐明抗菌药物的作用机理,也为寻找新药开拓了新的途径。例如根据抗代谢学说发现抗肿搐药·利尿药和抗疟药等。药物结构与生物活性关系的研究也随之开展,为创制新药和先导物提供了重要依据。30比~40年代发现的化学药物最多,此时期是药物化学发展史上的丰收时代。 进人50年代后,新药数量不及初阶段,药物在机体内的作用机理和代谢变化逐步得到阐明,导致联系生理、生化效应和针对病因寻找新药·改进了单纯从药物的显效基团或基本结构寻找新药的方法。例如利用潜效(Latentiation)和前药(Prodrug)概念,设计能降低毒副作用和提高选择性的新化合物。1952年发现治疗精神分裂症的氯丙嗪后·精神神经疾病的治疗,取得突破性的进展。非甾体抗炎药是60年代中期以后研究的活跃领域,一系列抗炎新药先后上市。 60年代以后构效关系研究发展很快,已由定性转向定量方面。定量构效关系(QSAR)是将化合物的结构信息、理化参数与生物活性进行分析计算,建立合理的数学模型,研究构-效之间的量变规律,为药物设计、指导先导化合物结构改造提供理论依据。QSAR常用方法有Hansch线性多元回归模型,Free-WilSon加合模型和Kier分子连接性等。所用的参数大多是由化合物二维结构测得,称为二维定量构效关系(2D-QSAR)。50~60年代是药物化学发展的重要时期70年代迄今,对药物潜在作用靶点进行深入研究,对其结构、功能逐步了解。另外,分子力学和量子化学与药学科学的渗透,X衍射、生物核磁共振、数据库、分子图形学的应用,为研究药物与生物大分子三维结构,药效构象以及二者作用模式,探索构效关系提供了理论依据和先进手段,现认为SD-QSAR与基于结构的设计方法相结合,将使药物设计更趋于合理化。 对受体的深入研究·尤其许多受体亚型的发现,促进了受体激动剂和秸抗剂的发展,寻找特异性地仅作用某一受体亚型的药物,可提高其选择性。如β和α肾上腺素受体及其亚型阻滞剂是治疗心血管疾病的常用药物;组胺H2受体阻滞剂能治疗胃及十二指肠溃疡。内源性脑啡酞类对阿片受体有激动作用,因而呈现镇痛活性,目前阿片受体有多种亚型(如δεγηκ等)为设计特异性镇痛药开拓了途径。 酶是高度特异性的蛋白质,生命活动许多是由酶催化的生化反应,故具有重要的生理生化活性。随着对酶的三维结构、活性部位的深入研究,以酶为记点进行的酶抑制剂研究,取得很大进展。例如通过干扰肾素(Renin)-血管紧张素(Angiotensin)-醛固醇(Aldosterone)系统调节而达到降压效用的血管紧张汞转化酶(ACE)抑制剂,是7O年代中期发展起来的降压药。一系列的ACE抑制剂如卡托普利、依那普利·赖诺普利等已是治疗高血压、心力衰竭的重要药物。3羟基-3-甲戊二酰辅酶A(HMG-CoA)还原酶抑制剂,对防治动脉粥样硬化、降血脂有较好的疗效。噻氯匹定可抑制血栓素合成酶·用于防治血栓形成。 离子通道类似于活化酶存在于机体的各种组织,参与调节多种生理功能。7O年代末发现的一系列钙拮抗剂(Calcium Antagonists)是重要的心脑血管药,其中二氢砒锭啶类研究较为深入·品种也较多,各具药理特点。近年发现的钾通通调控剂为寻找抗高血压、抗心纹痛和I类抗心律失常药开辟了新的途径。 细胞癌变认为是由于基因突变导致基因表达失调和细胞无限增殖所引起的,因此可将癌基因作为记点,利用反义技术(antisense technology)抑制细胞增殖的方法,可设计新型抗癌药。 8O年代初诺氟沙星用于临床后,迅速掀起喹诺酮类抗菌药的研究热潮,相继合成了一系列抗菌药物,这类抗菌药和一些新抗生素的问世,认为是合成抗菌药发展史上的重要里程碑。 寻找内源性活性物质是药物化学研究的内容之一,近年来发现许多活性多肽和细胞因子·如心钠素(ANF)是8O年代初从鼠心肌匀浆分离出的心房肽,具有很强的利尿、降压和调节心律的作用,内皮舒张因子(EDRF)NO是同时期证实由内皮细胞分泌具有舒张血管作用的物质,其化学本质后证实是一氧化氮(Ho)。它是调节心血管系统、神经系统和免疫系统功能的细胞信使分子,参与机体的多种生理作用,9O年代后,有关NO的研究已成国际的热点。NO供体和NO合酶抑制剂的研究正方兴未艾,将为心血管抗炎药等开拓新的领域。 生物技术(生物工程)是近2O年发展的高新技术,医药生物技术已成为新兴产业和经济生长点。9O年代初以来上市的新药中,生物技术产品占有较大的比例,并有迅速上升的趋势。通过生物技术改造传统制药产业可提高经济效益,利用转基因动物-乳腺生物反应器研制、生产药品,将是21世纪生物技术领域研究的热点之一。 近年来发展的组合化学技术,能合成数量众多的结相关的化合物,建立有序变化的多样性分子库,进行集约快构速筛选,这种大量合成和高通量筛选,无疑对发现先导化合物和提高新药研究水平都具有重要意义。 70-90年代,新理论、新技术、学科间交叉淮透形成的新兴学科,都促进了药物化学的发展,认为是药物化学承前启后,继往开来的关键时代。 人们认为20世纪中、后期药物化学的进展和大量新药上市,归纳为三方面主要原因:(l)生命科学,如结构生物学、分子生物学、分子遗传学、基因学和生物技术的进展,为发现新药提供理论依据和技术支撑(2)信息科学的突飞猛进,如生物信息学的建立,生物芯片的研制,各种信息效据库和信息技术的应用,可便捷地检索和搜寻所需安的文献资料,研究水平和效率大为提高;(3)制药企业为了争取国际市场,投入大且资金用于新药研究和开发(R&D),新药品种不断增加,促进了医药工业快速发展。希望采纳
