(一)取兔子一只,体重三公斤,乌拉坦全麻。气管切开,气管套管,联马利氏气鼓,于记纹鼓上记录呼吸曲线,同时作颈动脉套管,联水银柱浮标,于记文纹鼓上同步记录血压曲线,并同时观察其心前导联心电图。得到全麻兔的呼吸、血压曲线和心电图,随后以每公斤体重1.2克剂量的鹤草芽浸膏灌胃(按公斤体重计算,相当于临床驱绦剂量的30倍),观察2.5小时,其呼吸,血压曲线和心电图,基本上无何变化。于是将上述剂量的鹤芽草浸膏重复灌胃一次,乃于半小 (a) take a rabbit, weighing three kilograms, urethane general anesthesia. Tracheotomy, tracheal cannula, Marmale’s air drum, recording respiratory curve on the recording drum, simultaneous carotid cannula, mercury buoy, simultaneous recording of blood pressure curve on Wenwen drum, and simultaneous observation Its precordial ECG. The respiration, blood pressure curve, and electrocardiogram of general anesthetized rabbits were obtained, followed by intragastric administration of Herba peripabra extract at a dose of 1.2 grams per kilogram of body weight (calculated as kilogram body weight, equivalent to 30 times the clinical flooding dose), and observed for 2.5 hours. Breathing, blood pressure curves, and electrocardiograms basically do not change. Therefore, the above-mentioned dose of Hebi grass extract was repeatedly administered to the stomach once, which was half-small
