该实验先后在犬体及人体进行。三条巳自然感染丝虫的犬,在在针刺大椎穴前后观察了其24小时末鞘血液内微丝蚴的周期性。结果在针刺前,大微丝蚴可日夜出现,高峯在午夜12时至次日3时,当针刺后(9时,12时共两次,各仃针5分钟)犬微丝蚴数则平均降低30——40%。此外,在针刺前的同一时间内计算犬静脉与毛细血管内40立方毫米血量的微 The experiment has been carried out in dogs and humans. Three dogs who were naturally infected with filarial worms were observed for their periodicity of 24-hour end-sheath microfilariae before and after acupuncture. Results Before the acupuncture, the big microfilariae could appear day and night. The peak was between 12 midnight and 3 o’clock the next day. After the acupuncture (twice at 9 o’clock and 12 o’clock for 5 minutes) The average decrease of 30 - 40%. In addition, at the same time before acupuncture, calculate the micro-volume of 40 mm3 of blood in the canine vein and capillaries
