| 摘 要： | 脾虚证的临床表现以消化系统功能障碍为主,其中胰腺外分泌功能减退明显,且伴有食欲与体质量的显著下降.胰多肽(PP)是胰岛周边F细胞分泌的主要胃肠激素,对胰腺外分泌功能与食欲的调节有抑制作用,可导致氧化代谢增强,引起体质量下降.本试验旨在揭示大鼠胰岛胰多肽分泌变化与脾虚证发病之间的关系.笔者以利血平脾虚大鼠模型为研究对象,采用SP染色进行免疫组织化学研究,观察大鼠胰岛中胰多肽免疫阳性物质的分布情况.脾虚组与对照组的大鼠胰岛中胰多肽免疫阳性物质面积与胰岛面积百分比相比,胰头部分未见明显差异(P＞0.05);但脾虚组胰中、胰尾的PP免疫阳性物质所占面积极显著大于对照组(P＜0.01).结果表明,脾虚证大鼠胰岛中胰多肽总分泌量极显著增加.因此,胰多肽的分泌增加是导致脾虚证动物出现胰腺外分泌功能低下、食欲减退以及体质量下降的主要因素.

| Abstract: | The spleen deficiency syndrome plays a significant role in the concept of Chinese traditional medicine.Its primary clinical manifestation is the functional impairment of digestive system,showing pancreatic external secretion declined,food intake reduced and weight lose.On the other hand,the pancreatic polypeptide(PP),released principally from released from pancreatic islet F-cells,has well-proved function including the inhibition of pancreatic secretion,relaxation of gallbladder,increase oxygen consumption ... |
