摘要: 目的:研究雄性激素对杜氏利什曼原虫感染的C57BL/6J小鼠骨髓巨噬细胞(BMMs)水平的影响。方法:用雄性激素处理小鼠3wk后,收集BMMs,培养5d后,按BMMs前鞭毛体=110的比例,接种杜氏利什曼原虫,用吉姬氏染色法观察不同时相的感染水平。结果:与植物油处理的对照组相比,雄性激素处理的小鼠BMMs对前鞭毛体较为易感,并随着感染时间的延长其感染水平增高(感染后3h,P<0.05;24h,48h和72h,P<0.01)。结论:雄性激素可增加杜氏利什曼原虫对BMMs 的感染水平, 这可能与雄性激素诱导的免疫抑制作用有关。

Abstract: AIM: To investigate the effect of the male sex hormone, testosterone (Te), on Leishmania donovani infection levels of bone marrow derived macrophages(BMMs) from female mice of strain C57BL/6J. METHODS: After three weeks of Te treatment, the BMMs were isolated, challenged with L.donovani at a ratio of 10 to 1 promastigotes per macrophage, and the infection levels of different time points were monitored by Giemsa staining. RESULTS: BMMs from Te treated mice had a significantly increased initial uptake(3 h post infection, P < 0.05) of promastigotes and carried heavier infection levels at all time points (24 h, 48 h, 72 h post infection, P< 0.01) , compared with those from oil treated controls. CONCLUSION: Te can increase L. donovani infection levels of BMMs, being possibly related to Te-induced immuno suppression.
