促腸泌素 的英文怎麼說
中文拼音 [cùchángbìsù]
促腸泌素
英文
enterocrinin-
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。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。
