  1. The present studies aimed to find the responses of neurons and glias in the target and other brain areas of the linear accelerator - irradiated rats. in the first experiment, time - dependent neurons changes in the brain after hemispheric irradiation at an single - fraction maximal dose of 20 gy were observed by investigating the expression of an immediate early gene, fos protein. the results shown : compared with that of the un - radiated rats, the expression of fos protein in the irradiated brain decreased distinctly 24 hours and 1 week after irradiation

    首先，利用即刻早期基因fos的表達，做了同一照射劑量（ 20gy ）照射大鼠半腦后不同存活期間（ 1d ， 7d ， 14d ， 2ld ， 28d ）大鼠全腦神經元動態變化的觀察，發現：受照射后1d 、 7d大鼠腦內各部位fos蛋白表達均明顯減少，隨著時間的延長，其fos免疫反應性細胞數量逐漸增加，照射后28d ，延髓、第四軍醫大學碩士學位論文腦橋內hs免疫陽性細胞數量恢復並超過正常對照組水平，但中腦、間腦及端腦內未恢復到正常對照組水平。
  2. 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」 。
