氨茶碱是临床常用的平喘药.近期有人曾将它注入大鼠侧脑室及猫的第三脑室,发现具有升高血压的作用.而我们将其注入家兔的双侧侧脑室,却得到相反的结果,血压非但不见上升,反见明显下降,见效甚快,持续时间较长.现将实验方法及结果介绍如下. Aminophylline is commonly used in clinical antiasthmatic medicine.It has been recently injected into the rat ventricle and cat third ventricle and found to have elevated blood pressure and we injected it into the rabbit’s bilateral lateral ventricle, Obtained the opposite result, not only the blood pressure did not rise, the apparent decline, effective quickly, longer duration. Now the experimental methods and results are described below.
