In order to investigate the effect of IFN-γon the expression of TNF-αin the hypothala- mus-pituitary-ovary axisof RU486-induced aborted SD rats, RU486 was used to establish the abortion model, then the aborted rats were administrated with different doses of IFN-γintraperitoneal injection, the method of immunohistochemical ultrasensitive SP was us- ed to study the variation of positive TNF-αcells in hypothalamus, pituitary, ovary and uterus in normal pregnant group A, aborted model group B and three different doses of IFN-γgroup C,D,E. The main goal of this research was to study whether the low dose of IFN-γcould have a protective function to pregnancy and the mechanism of its function so as to provide morph- ologic basis for the scientific using of IFN-γin the process of animal abortion control.

为探讨IFN-γ对流产大鼠下丘脑-垂体-卵巢轴(hypothalamus-pituitary- ovary-axis，HPOA )TNF-α表达的影响，本试验用米非司酮(RU486)建立SD大鼠流产模型，通过腹腔注射不同剂量IFN-γ，采用超敏感免疫组织化学SP法(链霉素抗生物素—过氧化物酶法)，观察了孕13天(d13)SD大鼠正常妊娠A组、流产模型B组、不同剂量IFN-γC、D、E组下丘脑、垂体、卵巢、子宫TNF-α的表达变化，探讨低剂量IFN-γ对妊娠是否有保护作用及其作用机制，期望能为在妊娠过程中如何科学应用IFN-γ防止动物流产提供形态学依据。
