关于交感缩血管神经,自Claude Bernard(1852)在兔耳上发现以来,一百多年间经各国学者的研究,已有大量事实和较清楚的了解。但对于交感舒血管神经,却十分模糊和混乱;材料不多。十多年前一般教学参考书和流行的看法是:交感舒血管神经有两类——肾上腺素能和胆碱能的,各种动物分布也不一样;狗和野兔有大量胆碱能纤维,猫大部分为肾上腺素能的,猴和家兔则无此两类纤维。在人类则有争论。至于说到它们的中枢定位和生理意义,材料更感贫乏。近十余年来,Uvnas和Lindgren等利用测量器官血流量和脑走向器的办法,已能精确测定即使在血压无变化的情况下,骨骼肌血流量的变 About the sympathetic vasoconstriction nerve, since Claude Bernard (1852) discovered in the rabbit ear, a hundred years of scholars from various countries have a large number of facts and a clearer understanding. But for the sympathetic vasodilator, but very vague and confusing; few materials. Ten years ago, the general teaching reference books and popular view is: sympathetic vasodilator has two types - adrenergic and cholinergic, a variety of animal distribution is not the same; dogs and rabbits have a large number of cholinergic fibers, Most cats are adrenergic, while both monkeys and rabbits do not have these two types of fibers. In humans there is argument. As far as their central location and physiological significance are concerned, the material is more impoverished. For more than ten years, Uvnas and Lindgren and other measurements using organ blood flow and brain approach, has been able to accurately measure even in the case of no change in blood pressure, skeletal muscle blood flow changes
