[ Methed]Sixty-four 6-week-old healthy Kunming mice weighing about 25 g were randomly divided into four groups （ n = 16）, half male and half female. Mass ratios of basic diet to leaf meal of Tephrosia canadida DC. in group A, group B, group C and group D were 10：0, 4：1, 3：2 and 2：3, respectively. After 35-d feeding, the effects of Tephrosia canadida DC. on growth, blood and organs of mice were observed. [ Resultl Dudng the trial, all mice had normal activities, and no death and no abnormal blood index were observed. All organs of the mice in the experimental groups had no visible pathological lesion, and organ indexes had no significant difference between the experimental groups and the control group. Except that slightly abnormal histological changes appeared in liver and kidney of the mice in the group C and D, no histological change was ob- served in other organs of the experimental mice. [ Conclusion] Tephrosia canadida DC. have no adverse effects on mice, which provides a refer- ence for research about their safety in feed of other animals.展开更多
目的研究漏芦乙醇提取物对D-半乳糖致衰老小鼠影响。方法D-半乳糖制作小鼠衰老模型,比色分析法测定小鼠大脑皮质超氧化物歧化酶(superoxide d ismutase,SOD)、单胺氧化酶(monoam ine oxidase,MAO)的活性及丙二醛(m alond-ialdehyde,MDA...目的研究漏芦乙醇提取物对D-半乳糖致衰老小鼠影响。方法D-半乳糖制作小鼠衰老模型,比色分析法测定小鼠大脑皮质超氧化物歧化酶(superoxide d ismutase,SOD)、单胺氧化酶(monoam ine oxidase,MAO)的活性及丙二醛(m alond-ialdehyde,MDA)的含量,同步观察电子显微镜下的组织学变化。结果漏芦提取物可提高D-半乳糖所致大鼠脑组织SOD活性、降低MDA含量,抑制MAO活性;电子显微镜观察到漏芦提取物可以减轻D-半乳糖导致的线粒体等超微结构的改变。结论漏芦提取物对D-半乳糖致衰老小鼠具有抗衰老作用。展开更多
