一、从氨茶碱谈起氨茶碱和其他嘌呤类药物的血管扩张作用,特别是对冠状血管的扩张作用,人所熟知。多少年来的动物实验资料指明,氨茶碱也能扩张脑血管而增加脑血流。如在猴子实验中,氨茶碱或咖啡因静脉注射后,均能轻度增加脑血流量;当将药物作颈动脉内注射时,则能使脑血流增加约60%。由于在增加脑血流的同时,往往出现血压下降与脑脊髓
Aminophylline to talk about the theophylline and other purine drugs vasodilator effect, especially for the expansion of coronary vessels, is well known. Years of animal experimental data indicate that aminophylline can also increase cerebral blood flow and cerebral blood flow. As in monkey experiments, intravenous aminophylline or caffeine increased cerebral blood flow slightly; when injected intracarotidly, the drug increased cerebral blood flow by about 60%. Due to increased cerebral blood flow at the same time, often with blood pressure and cerebral spinal cord
