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。

The sample was isolated by sephadex G-25 gel filtration column after concentration. Then bioactivity was assayed by Candida albicans. The chemical components were isolated and identified by GC-MS. GC determined the relative percentage content of the extract, nine kinds of components were separated, identified and accounted for about 82.12%, the major compound was propenyl methyl disulfide.

浓缩后的样品通过Sephadex G-25凝胶柱分离提纯其中的有效成分，以白色念球菌进行生物活性测定，并用气相色谱-质谱法对其化学成分进行分离鉴定，GC法测定各种化合物的相对百分含量，共鉴定了9种成分，约占总提取物的82.12％，其中，主要物质是甲基丙烯基二硫化物。
