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 experimental vitiligo models were prepared by chemical decolour method in Guinea Pigs. And we choose the Meladinines recommeded level (0.15%) as high concentration, use the high, middle and low concentration levels (0.15%, 0.075 %, 0.03 %) of LMOP gels to progress the pharmacodynamics comparative study, 8-MOP tincture was used as controll group, observing the melanin distribution, the number of DOPA active cells, the number of hair follicles contented melanin, the levels of ChE and MDA of the experimental vitiligo models.

用化学脱色法制备豚鼠实验性白癜风动物模型，以市售敏柏宁酊的推荐使用浓度(0.15％)为最高浓度，设定LMOP凝胶低、中、高三个浓度组(0.03％，0.075％，0.15％)，进行药效学比较性研究，以8-MOP酊剂(敏柏宁酊稀释至含8-MOP 0.15％)为对照，考察其对皮肤黑素分布、DOPA阳性细胞数、含黑素毛囊数、胆碱酯酶及丙二醛的影响。

The pressor effect of adenosine was due to carotid body cheoreceptor activation. However, a slight increase of ABP induced by intracarotid bolus injection of adenosine following the section of carotid sinus nerves was observed in a few rats, which implied that the central effect might be involved in the pressor effect of adenosine. The delayed effect of adenosine may be attributed to the direct actions (including the negative chronotropic action, thenegative dromotropic action, the negative inotropic action and the vasodilator effect) of adenosine on the heart and blood vessels.

前一效应主要与颈动脉体化学感受器的激活有关，但在少数动物，颈动脉内注射腺苷的升压效应在切除窦神经后并未完全消除，表明腺苷有可能进入神经中枢而发挥作用；后一效应可能由腺苷直接作用于心脏和血管，通过其负性变力、变时、变传导和血管扩张等作用，导致心脏自律性降低，输出量减少和外周阻力下降。

Methods Forty-eight healthy black and blue rabbits were chosen and divided into 6 groups at randomly. Experimental groups were performed surgery with CO2 laser sclerectomy in both eyes. Contents of nitric oxide and malonyldialohyed and the activity of Na(superscript +)-K(superscript +)-ATPase were tested with biochemical assays.
