tolerance dose
5.The results show as follow:1. By gastrogavage , the maximum tolerance dose (MTD) of Eucommia ulmoides extract is over 18.52g/kg weight. The median lethal dose(LD50) of mice intraperitoneally injected Eucommia ulmoides extract solution is 2.57±0.15g/kg,95%of the limit of trust is 2.73 g/kg~2.42g/kgo .
7.Bupivacaine (0.5 -1.5mg/kg iv ) could significantly antagonize arrhythmias. induced by aconitine and BaCI2 in rats(P<0.05 or P< 0. 01 ), prevent ventricular fibrillation induced by chloroform in mice (P<0. 05 or P<0. 01 ), increase tolerance dose of ouabain to produce arrhythmias and cardiac arrest in guinea pigs (P<0. 05 or P<0. 01 ).
8.Results NO-1886 reduced postprandial serum TG and FFA levels of New Zealand rabbits during the fat-tolerance test in dose-dependent manner.
