摘要: 背景与目的: 研究杜香熊果酸提取物对小鼠遗传损伤是否具有保护作用。 材料与方法: 以环磷酰胺(cyclophosphamide,CP) 所导致的遗传损伤小鼠作为损伤模型,采用小鼠骨髓嗜多染红细胞微核试验,检测杜香熊果酸提取物对遗传损伤的保护作用。 结果: 杜香熊果酸提取物1.16、2.30、4.60 g/kg的骨髓嗜多染红细胞微核发生率分别为2.00‰±0.37‰、2.00‰±0.45‰、1.80‰±0.37‰ ,与正常组(2.00‰±0.45‰)比较差异均无统计学意义(P>0.05),与阳性对照组(24.00‰±0.71‰)其差异均具有统计学意义 (P<0.01)。杜香熊果酸提取物1.16、2.30、4.60 g/kg加环磷酰胺组骨髓嗜多染红细胞微核发生率分别为17.20‰±1.24‰、16.40‰±1.53‰、16.00‰±0.51‰,明显低于阳性对照组(24.00‰±0.71‰),其差异均具有统计学意义(P<0.05)。 结论: 杜香熊果酸提取物对遗传损伤有保护作用。

Abstract: BACKGROUND AND AIM: To study the protective effects of ursolic acid extract from Ledum Pulastre L. against genetic damage. MATERIALS AND METHODS: We used mice with genetic damage caused by cyclophosphamide,(CP), as a model of injury. Through mouse cells of bone marrow PCE micronuclear test, the protective effects of ursolic acid extract on genetic damage was measured. RESULTS: The bone marrow cells-nuclear PCE rates of ursolic acid extract at 1.16,2.30,4.60 g/kg dose were 2.20‰ ±0.37‰,2.00‰ ±0.45‰,1.80‰±0.37‰, respectively. There was no significant difference with the normal group (2.00‰±0.45‰) (P>0.05), but showed a significant difference with positive group (24.00‰±0.71‰)(P<0.01). The bone marrow cells-nuclear PCE rates of ursolic acid at 1.16,2.30,4.60 g/kg dose with added CP were 17.20‰±1.24‰,16.40‰±1.53‰,16.00‰±0.51‰,respectively,significantly different from the positive group(24.00‰±0.71‰)(P<0.05). CONCLUSION: Ursolic acid extract from Ledum Pulastre L. demonstrated protective effects against genetic damage.
