摘要: 目的 研究细脚拟青霉代谢物提取物(bioactive compounds from paecilomyces tenuipes, BCPT) 的小鼠急性毒性及对慢性应激大鼠脑组织脂质过氧化的影响。方法 采用慢性不可预见性应激(CUS) 法建立大鼠抑郁模型;用紫外分光光度计测定大鼠脑组织中GSH-PX 、CAT 、SOD 活性和MDA 、NO 含量。采用小鼠最大耐受量法, 观察BCPT 的急性毒性。结果 BCPT 能提高CUS 大鼠脑组织中GSH-PX 、CAT 、SOD 活性, 降低CUS 大鼠脑组织中MDA 、NO 含量;小鼠最大耐受量为9 g·kg-1结论 BCPT 毒性小,其抗抑郁作用机制可能与抗氧化有关。

Abstract: AIM: To study the acute toxicity of bioactive compounds from paecilomyces tenuipes (BCPT) and the effect of BCPT on lipid peroxidation of brain in chronic stress model (CMS) of depression in rats.METHODS: The depression animal model was induced by chronic unforeseeable stress (CUS).The maximally tolerated dose (MTD) was used to detect the acute toxicity of BCPT.UV spectrophotometer analysis technique was used to detect the activity of SOD, GSH-PX and CAT,and content of MDA and NO in rat's brain.RESULTS: The MTD of BCPT was 9 g·kg-1.BCPT could obviously enhance the activities of SOD, GSH-PX and CAT, and also significantly inhibit the increase of MDA and NO content in brain in CMS rats.CONCLUSION: BCPT has little toxicity and produces an antidespressant-like effect in antioxidation in CMS rats.

Key words: paecilomyces, chronic stress, maximum tolerable dose, lipid peroxidation
