目的:探讨莲子心总生物碱(LPTA)的毒副作用,以对莲子心总生物碱作出安全性评价。方法:小鼠急性毒性试验中一次性给予最大灌胃量5000 mg·kg-1莲子心总生物碱,观察小鼠中毒症状。长期口服毒性实验,SD大鼠随机分为4组,分别按照400、200、100 mg·kg-1·d-1的剂量给予灌胃LPTA的给药组,对照组给予等量体积0.3%羧甲基纤维素钠;连续服用30 d。结果:在急性毒性试验中给予5000 mg·kg-1莲子心总生物碱对小鼠不产生毒性作用。在长期毒性试验中,除不同剂量给药组SD大鼠血清尿素氮与对照组具有显著性差异(P<0.05),高、中剂量组SD大鼠血糖含量与对照组有明显差异(P<0.05)外,余下指标与对照组相比均无明显差异。中、低剂量组大鼠肝组织病理切片与对照组相比均无明显异常,高剂量组细胞核数目略减少,但肝小叶结构正常。结论:莲子心总生物碱对小鼠最大耐受剂量为5000 mg·kg-1,同时灌胃给药400 mg·kg-1·d-1莲子心总生物碱对大鼠无毒副作用。
目的:探討蓮子心總生物堿(LPTA)的毒副作用,以對蓮子心總生物堿作齣安全性評價。方法:小鼠急性毒性試驗中一次性給予最大灌胃量5000 mg·kg-1蓮子心總生物堿,觀察小鼠中毒癥狀。長期口服毒性實驗,SD大鼠隨機分為4組,分彆按照400、200、100 mg·kg-1·d-1的劑量給予灌胃LPTA的給藥組,對照組給予等量體積0.3%羧甲基纖維素鈉;連續服用30 d。結果:在急性毒性試驗中給予5000 mg·kg-1蓮子心總生物堿對小鼠不產生毒性作用。在長期毒性試驗中,除不同劑量給藥組SD大鼠血清尿素氮與對照組具有顯著性差異(P<0.05),高、中劑量組SD大鼠血糖含量與對照組有明顯差異(P<0.05)外,餘下指標與對照組相比均無明顯差異。中、低劑量組大鼠肝組織病理切片與對照組相比均無明顯異常,高劑量組細胞覈數目略減少,但肝小葉結構正常。結論:蓮子心總生物堿對小鼠最大耐受劑量為5000 mg·kg-1,同時灌胃給藥400 mg·kg-1·d-1蓮子心總生物堿對大鼠無毒副作用。

Objective: To investigate total alkaloids extracted from lotus plumula (LPTA) side effects, in order to confirm the safe use of it. Methods: In acute toxicity study, total alkaloids were administrated by oral gavage at a dose of 5000 mg·kg-1 in mice. In long-term toxicity study, the total alkaloids of 400, 200 and 100 mg·kg-1·d-1 were given orally to groups of rats for 30 consecutive days. Results: The total alka-loids at a dose of 5000 mg·kg-1 produced no signs of toxicity or mortality in any of the tested animals in acute toxicity study. In the long-term toxicity tests, there was no significant difference in serum biochemi-cal parameters except that serum urea nitrogen and blood glucose levels at the highest dose group were different from that of the control group (P<0.05). Compared with the control group, no abnormality of inter-nal organs was observed in medium and low dose group, however, the number of nuclear decreased slightly in the highest dose group. Conclusions: The maximum tolerated dose of LPTA in mice was 5000 mg·kg-1 and administrated LPTA by oral gavage at a dose of 400 mg·kg-1·d-1 makes no side effects in rats.
