具有能升高血压物质的血管張力素(Angiotensin)之发現,为推究高血压原因及了解控制循环中腎脏所起之作用有了新希望。 [一]在身体和情緒紧張的經常变动情况下,身体不同部位組織之血液供应,亦需要經常变动。心血管系統通过神經系統之調整来迎合此种要求。当某区組织較急地需要血液供应时,即赖神經調节血管管腔,使他区组织的血液轉移到該处。关于此种調节作用还了解得不够,需要继續努力研究。例如,当需要全部脑組織从事活动时,能
The discovery of angiotensin, a substance that increases blood pressure, offers new hope for extrapolating the causes of hypertension and understanding the role that the kidneys play in controlling circulation. [1] With the frequent physical and emotional changes, the blood supply to different parts of the body also needs to be constantly changed. The cardiovascular system caters to this demand by adjusting the nervous system. When a district organization more urgently need blood supply, that is, the nerve nerves regulate vascular lumen, so that his area of ?? blood translocation. The regulatory role is not well understood and needs to be further studied. For example, when all brain tissue is needed for activity
