近年来,由于电镜、组织免疫细胞化学及免疫荧光技术的迅速发展,对胰腺内、外分泌之间相互影响的研究有了深入的发展,本文就胰岛激素对外分泌作用方面的研究近况作简要综述。 一、胰腺内、外分泌血供的关系 在人及一些动物、胰岛的小动脉及毛细血管较其周围的外分泌组织之小动脉及毛细血管的管径要宽,而且排列紧密并形成广泛的血窦样结构。胰岛的血管与外分泌腺的相互联结,而胰岛内毛细血管之压力大于外分
In recent years, due to the rapid development of electron microscopy, tissue immunocytochemistry and immunofluorescence techniques, the research on the interaction between exocrine and exocrine pancreatic has been further developed. This review summarizes the recent progress in the study of exocrine function of pancreatic islets. First, the relationship between pancreatic exocrine blood supply In humans and some animals, islet arterioles and capillaries than the surrounding exocrine tissue of small arteries and capillaries to be wide, and arranged in close and the formation of a wide range of sinusoids Sample structure. The islets of the blood vessels and exocrine glands connected to each other, and the pressure within the islet capillaries greater than the external points
