中文拼音 [wèichángtài]
胃腸肽
英文
gastrointestinal peptide-
Casein of dairy is the important sources of those peptides and can release them during gastronintestinal digestion, or enzyme proteolysis
摘要酪蛋白是生物活性肽的重要來源，可以通過體內的胃腸消化和食品加工過程中的酶解將其釋放出來。Background : ghrelin is a 28 - amino acid endogenous peptide recently identified in the secretory granules of x / a - like cells in the rat stomach, which can act on the growth hormone secretagogue receptor to accelerate the secretion of growth hormone. it was identified that ghrelin - immunoreactive cell and its receptor localize in areas of brain, such as hypothalamus ( pvn, arc ), hippocampus, adenohypophysis and so on. motilin is a 22 - amino acid peptide secreted from the upper part of the small intestine, which regulates the interdigestive motility of gastric
背景資料： ghrelin是新發現的由28個氨基酸組成的內源性腦腸肽，由胃部泌酸腺x / a樣內分泌細胞分泌， ghrelin免疫活性神經元及其受體在中樞神經系統中如下丘腦室旁核（ paraventricularneucleus ， pvn ） 、弓狀核（ arcuatenucleus ， arc ） 、海馬區及腺垂體等均有不同濃度的分佈，可與生長素促泌物受體（ growthhormonesecretagoguereceptor ， ghsr ）結合促進生長素（ growthhormone ， gh ）分泌。The endocrine cells in the digestive and glands of alligator sinensis embryos aged from 8th to 55th day were localized and compared by using immunohistochemical method with thirteen kinds of antiseras of hormone. during the development of pancreas in alligator sinensis embryos, somatostatin ( ss ) immunoreactive ( ir ) cells, 5 - hydroxytryptamine ( 5 - ht ) - ir cells, glucagon ( glu ) - ir cells, epidermal growth factor ( egf ) - ir cells appeared on 18th day. no p53 protein - ir cell, gastrin - ir cell, testosterone - ir cell, chromogranin a - ir cell, vasoactive intestinal polypeptide - ir cell, epithelial membrane antigen - ir cell or insulin - ir cell was found in the pancreas of alligator sinensis embryos
本實驗採用免疫組織化學技術，應用13種不同的抗血清，對孵育時間8 ? 55天揚子鱷胚胎消化道及消化腺內分泌細胞的種類進行鑒別、定位和比較，結果如下：揚子鱷胚胎胰腺中，生長抑素、 5 ?羥色胺、胰高血糖素、表皮生長因子、胰多肽免疫反應陽性細胞出現于第8天； p物質免疫陽性細胞出現于第18天； p53 、胃泌素、睪酮、嗜鉻素a 、血管活性腸肽、上皮膜骯原、胰島素免疫陽性細胞在各期揚子鱷胚胎胰腺中均未發現。Purposes : enhancement of insulin secretion from the islet b cells is a principal goal for treatment of patients with type 2 diabetes. some gastrointestinal hormones are associated with insulin secretion
目的：胰高血糖素樣肽- 1 （ glucagon - likepeptide - 1 ， glp - 1 ）是一種組織特異性的胃腸道激素，主要由回腸末端l細胞、胰腺內分泌部a細胞以及神經細胞合成和分泌。In addition, the stomach contained glu - ir cellsn gas - ir cells and vip - ir cells, and the duodenum contained glu - ir cells and gas - ir cells. different endocrine cells varied from one to another in the distribution pattern, the stage of appearance and the number. no glu - ir cell, gas - ir cell or vip - ir cell was found in the oesophagus and no vip - ir cell in the duodenum
另外，胚胎期揚子鱷消化道內分泌細胞的種類和分佈與成體有差異，胚胎期消化道檢出胰高血糖素、胰多肽和p物質免疫陽性細胞，而成體未檢出；胚胎期消化道中胃泌素、血管活性腸肽，生長抑素免疫陽性細胞分佈與成體消化道不同。Moreover, human ghrelin receptor exhibits a remarkable 50 % overall identity with human motilin receptor, therefore it was named as " raotilin - related peptide ". anatomical evidence showed that there are ascending and descending neuronal projections between pvn, bma and lower brain stem ( nts, dmx ), which participate in the regulation of gastric acid secretion and gastrointestinal motility. moreover, pvn is the center of appetite regulatory web
Pvn與低位腦干（延髓迷走復合體）及邊緣系統之間有密切的纖維聯系，且含有多種神經肽，參與胃酸分泌，胃腸活動等多種生理機能的調節，是影響消化道功能與攝食行為的重要中樞部分， pvn內胃動素可促進胃排空和攝食，而新發現的ghrelin /胃動素相關肽是否參與此核區對胃運動的調節機制及其可能的神經通路尚不明了。It was recognized as a brain - gut peptide since the peptide and its receptor exist in the central nervous system. previously, we demonstrated that motilin and motilides activates cells in paraventricular nuclei ( pvn ) reflected by increased gastric motility and induction of the immediate early gene c - fos in conscious rat, which suggests central motilin participates in the regulation of gastric motility. it was reported in 2001 that ghrelin is an appetite - stimu latory signal from stomach with structural resemblance to motilin
胃動素（ motilin ， mt ）是由小腸上段粘膜內分泌細胞合成並分泌的22個氨基酸組成的腦腸肽，調節消化間期胃運動， pvn內給予胃動素和胃動內酯（ motilides ）可增強清醒大鼠胃運動，中樞微量注射胃動素可誘導pvn中立即早期基因c - fos的表達，提示中樞胃動素參與胃運動的調控，人ghrelin和胃動素之間有36的相似性，而且二者的受體之間有50的相似性，因而有人稱ghrelin為「胃動素相關肽」 。Experimental study on effect of prescription with reinforcing the kidney and activating circulation ， purgation ， inducing resuscitation and activating circulation on neuropeptide and monoamine nervous transmitter in aged rats with gastrointestinal tract injury and brain ischemia
補腎活血、瀉下及開竅活血方藥對腦缺血胃腸損傷老齡大鼠神經肽和單胺神經遞質的影響。6 6 sjolund k, ekman r, lindgren s, rehfeld jf. disturbed motilin and cholycystokinin release in the irritable bowel syndrome. scand j gastroenterol 1996, 31 : 1110
