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。

A parser can decode the next symbol from an encoded input stream by walking down the tree from the root, at each step choosing the edge corresponding to the next input bit.

For example：/\ Symbol Code 0 1 ----------/ \ A 00 /\ B B 1 0 1 C 011 / \ D 010 A / 0 1 / D C 解码器可以解码输入的内容：让输入的流从这个树的根结点走到叶子结点，每次的前进都选择与流中下一位相同的一边。
