在生理学实验教学中,传统的循环功能调节实验是用哺乳动物(家兔、狗等)进行的。它难以做到既观察心跳又观察血压变化,而且费用高,学生操作机会少。为了找到一种简便、经济、又能直接观察心血管活动的实验方法,探索了用在体蟾蜍心脏同时进行血压和心搏的描记,以观察神经租体液因素对心血管活动的影响。 In physiology experiment teaching, the traditional regulation of circulatory function is carried out by mammals (rabbits, dogs, etc.). It is difficult to do both observe the heartbeat and observe changes in blood pressure, but also high costs, fewer students operating opportunities. In order to find a simple, economical, and direct observation of cardiovascular activity in experimental methods, we explored the simultaneous use of blood pressure and heartbeat tracing in vivo to observe the effects of neurotrophic factors on cardiovascular activity.
