摘要: 试验旨在探讨蜂王浆冻干粉(lyophilized royal jelly,LRZ)对D-半乳糖致衰老模型小鼠的抗氧化作用。以昆明种小鼠为研究对象,按体重随机分为正常对照组、模型对照组和低、中、高剂量(170、340、510 mg/kg)蜂王浆冻干粉组。除正常对照组外,其余各组小鼠每天颈背部皮下注射160 mg/kg D-半乳糖0.2 mL,正常对照组注射等量的生理盐水。试验组小鼠每天灌胃0.3 mL LRZ水溶液,对照组小鼠灌胃等量的蒸馏水,试验期49 d。测定血清、脑和肝脏组织匀浆中超氧化物岐化酶(SOD)、过氧化氢酶(CAT)的活力及丙二醛(MDA)的含量。结果表明,D-半乳糖致衰小鼠SOD活力和CAT活力均明显下降,MDA含量明显上升,与正常小鼠比较差异显著(P<0.05);340、510 mg/kg LRZ可以提高小鼠血清、脑、肝脏组织中的SOD和CAT活性,降低MDA含量,与衰老模型组相比有显著性差异(P<0.05)。说明LRZ能显著提高亚急性衰老小鼠的抗氧化能力,具有量效关系。

Abstract: To investigate the effects of lyophilized royal jelly (LRZ) on antioxidant abilities in aged mice induced by D-galactose. The subacute aged model mice were made by neck back subcutaneous injection of D-galactose continually. The mice were given three different doses of LRZ, 170, 340, 510 mg/kg,respectively, the effect of LRZ on the content of catalase (CAT), malondialdehyde (MDA), superoxide dismutase (SOD) in serum, liver and brain were observed after 49 d. The CAT, SOD activities in aged model group were significantly decreased (P<0.05), but MDA was significantly increased as compared to normal mice (P<0.05). While in the aged mice treated with LRZ 340 and 510 mg/(kg·bw), the activity of CAT and SOD were significantly increased and the content of MDA significantly decreased as compared to aged mice (P<0.05). LRZ had antioxidant effect in aged mice and showed dose-and-effect relationship.
