摘要: 研究了泥鳅肉骨泥对小鼠抗氧化指标的影响。将小鼠分为空白组、模型组、泥鳅低剂量组和泥鳅高剂量组四组。除空白组外,其余三组均颈背部皮下注射浓度为500 mg/kg·bw的D-半乳糖溶液,制备小鼠氧化衰老模型,空白组注射相同剂量的生理盐水。将泥鳅制成肉骨泥给小鼠灌胃。以小鼠体重计,给小鼠灌胃100 mg/kg·bw的泥鳅肉骨泥为泥鳅低剂量组,给小鼠灌胃500 mg/kg·bw的泥鳅肉骨泥为泥鳅高剂量组,其余两组均灌胃同剂量生理盐水。动物实验结束后取血清、肝脏检测氧化指标。结果显示,与空白组相比,模型组血清SOD、肝脏CAT活性均显著降低(p<0.05),而两个泥鳅肉骨泥组与空白组差异不显著。与空白组相比,模型组血清和肝脏MDA含量均显著增加(p<0.05),而两个泥鳅肉骨泥组与空白组差异不显著。另外,与空白组相比,模型组血糖显著降低(p<0.05),两个泥鳅肉骨泥组与空白组无显著差异。但是实验也表明,灌胃泥鳅肉骨泥对小鼠高、低密度脂蛋白影响不大,各组之间并无显著差异。Abstract: The effects of Misgurnus anguillicaudatus meat bone paste on antioxidant parameters in mice were investigated in this study. Mice were randomly divided into four groups:control group,model group,low-dose and high-dose misgurnus anguillicaudatus meat bone paste groups. The 500 mg/kg·bw D-galactose were injected subcutaneously into the naps of mice to induce aging model except the control group. Mice in the control group were injected with the same dose of physiological saline. Misgurnus anguillicaudatus were made into meat bone paste. The mice of low-dose and high-dose groups were given by gavage with Misgurnus anguillicaudatus meat bone paste solutions of 100 mg/kg·bw and 500 mg/kg·bw respectively. Meanwhile,mice in control and model groups were given by gavage with the same dose of physiological saline. Plasma and liver samples were used for determination of antioxidant parameters. In the model group,the activities of plasma superoxide dismutase(SOD) and liver catalase(CAT) were significantly decreased compared with the control group(p<0.05),and there were no significant differences among the control group,low-dose and highdose groups. In the model group,the content of malondialdehyde(MDA) in plasma and liver were significantly increased compared with the control group(p<0.05),while there were no significant differences among the control group,low-dose and high-dose groups. Plasma glucose concentrations in the model group were significantly lower than in the control group( p <0.05), and there were no significant differences among the control group,low-dose and high-dose groups. While this experiment also indicated that giving Misgurnus anguillicaudatus meat bone paste had little effect in high and low density lipoprotein in mice,no significant differences were found among the four groups.
