| 摘 要： | 作者研究了胸腺依赖抗原 (SRBC) (羊红血细胞 ,sheepredbloodcells ,SRBC)和非胸腺依赖抗原 (细菌脂多糖 ,lipopolysaccharide ,LPS)的免疫活化对黑线毛足鼠气味信号和内分泌状态的影响。成年雄鼠注射SRBS5天后 ,其气味的性吸引力下降 ,这种结果伴随着粪便中睾酮含量的下降。SRBC处理后 ,雄性气味吸引力降低 ,这在体液免疫反应低的雄性个体中最明显。与SRBC的作用相反 ,注射LPS的雄性个体的气味吸引力增加 ,成熟雌性个体用于嗅闻嗅觉刺激上的时间差异与经LPS和盐处理过的雄鼠的粪便中睾酮浓度的差异呈正相关。作者讨论了这两种相反的嗅觉效应的适应性意义

| Abstract: | We studied the influences of immune activation by thymus-dependent(sheep red blood cells,SRBC)and independent(bacterial lipopolysaccharide,LPS)antigens on odor signals and endocrine status in dwarf hamsters.Administration of SRBS to mature males resulted in a drop of sexual scent attractiveness of soiled bedding collected during 5 days after injection.This effect was accompanied with a decline of fecal testosterone.Reduction of the male scent attractiveness after SRBC treatment had maximum manifestation in males of dwarf hamsters with low humoral immune response to this challenge.Contrary to the effects of SRBC,males injected with LPS showed an increase of scent attractiveness.Differences in the time that mature females spent sniffing olfactory stimuli(LPS vs control),correlated positively with differences in concentration of testosterone in feces collected from LPS and saline treated males.We discuss the adaptive meaning of the opposite olfactory effects,which induced by activation of the nonspecific innate immunity with LPS and by activation of specific acquired immunity with SRBC |
