Rats were anesthetized with urethane(700mg/kg) andα-chloralose(35mg/kg),and the trachea,femoral artery and extemal jugular vein were cannulated respectively.

2取成年SD大鼠(250～350g)，乌拉坦(700mg/kg)和α-氯醛糖(35mg/kg)混合腹腔麻醉，行气管插管、颈外静脉插管、股动脉插管，游离一侧膈神经并穿线标记，缝合切口。

The efferent system could be suppressed by some anesthetics.

Methods Animals were randomly and equally divided into five groups: saline control group, positive drug control group, low-dose, medium-dose and high-dose crocetin group. Animals were anesthetized with urethane (1.2 g/kg), then followed by the perfusion of aconitine (10 μg/mL) through caudal vein in rats, or of ouabain (9 μg/mL) through external jugular vain in guinea pigs in a constant velocity of 0.1 mL/min, and the emergence time of ventricular fibrillation, ventricular extrasystole, ventricular tachycanlia and cardiac arrest were then detected and recorded. The recorded time was then translated to the cumulated amount of aconitine and ouabain. Experimental arrhythmia was induced by rapid injection of 4% CaCl2 (140 mg/kg), and the emergence time, persistence time, incidence and death of arrhythmia after the administration were observed.

将实验动物随机分为生理盐水组，阳性药物对照组，藏红花酸高、中、低剂量组，SD大鼠采用1.2 g/kg乌拉坦麻醉后，从尾静脉匀速(0.1 ml/min)灌注10μg/ml乌头碱溶液，豚鼠麻醉后从颈静脉匀速(0.1 ml/min)灌注9μg/ml哇巴因溶液，观察出现室性期前收缩、室性心动过速、室颤和心脏停搏的时间，然后换算成乌头碱和哇巴因的累积量；快速推注4%氯化钙(140 mg/kg)诱导大鼠心律失常，观察给药后心律失常出现时间、持续时间、心律失常发生数及死亡数。

方法1。记录乌拉坦麻醉的大鼠孤束核中与电刺激膈下迷走神经相关的神经元自发和诱发放电。

MATERIALS AND METHODS: The newborn mice were divided into DES, urethan and U+ DES groups. U was given in 500 mg/kg dose ip on the 14th day after they were born. DES was administered by ip on 1 d, 8 d, 15 d in the doses of 1/7, 2/7 and 4/7 LD50 of the day of treated.

材料与方法：ICR新生鼠，分设DES、乌拉坦和U+DES组。U在14d以500mg/kg腹腔注射(intraperitoneal，ip)；DES分别在1d、8d、15d ip，共3次，分别以注射日龄LD50的1/7、2/7、4/7为DES低、DES中、DES高组。

Ung tumors were induced by a single intraperitoneal injecting of urethan (500mg/kg) and multi intramuscular injecting of estrogen (50mg/kg) in mice, and the animals were administered orally with 0.02% or 0.2% of tea polyphenols simultaneously for 18 weeks to study its inhibitory effect.
