脏器微循环,是指各脏器的循环系统对细胞代谢最有关系的循环单位而言。微循环也可说是既能顺利调节各脏器的功能及细胞代谢,又易受到全身损害的循环系统。特别是胰腺,系由内分泌腺与外分泌腺构成,在外分泌组织中又混有内分泌细胞集合而成的胰岛(郎格罕氏岛),为一构造特异的脏器;且其位子腹腔内背侧,不便研究,故其微循环尚未搞清。作者等用大白鼠胰腺,对胰微循环及微血管构造进行了研究;对蛋白酶抑制剂(Protease inhibitor,PI)的作用,从微循环动态及超微形态方面探讨了其相关性。 胰微血管构造及循环动态
Organ microcirculation, refers to the circulatory system of various organs of the cell metabolism is most concerned about the cycle unit. Microcirculation can also be said that both the smooth regulation of the function of organs and cell metabolism, but also susceptible to systemic damage to the circulatory system. Especially the pancreas, which is composed of endocrine glands and exocrine glands, islets in the exocrine tissues mixed with endocrine cells (Langagen Island), is a specific organ; and its seat in the abdominal cavity of the dorsal , Inconvenience to study, so its micro-circulation has not yet figure out. The authors used pancreatic glands in rats to study the effects of pancreatic microcirculation and microvascular structure, and the role of protease inhibitors (PIs) in microcirculation and ultrastructure. Pancreatic microvascular structure and circulation dynamics
