Methods:202 lying –in women were randomly divided into two set ,observing a group was 102 ,contrasting a group was 100,pitocin 20U was used by adding 50g/L glucose nomal salines 500ml dripping in two groups after childbirth ,at the same time with administering carboprost methylate suppository 1mg via the rectum (depth 6cm is suitable)in the contrasting a group.

Fifty female patients who were selected to schedule for mammary gland tumor excision surgery, were divided into 2 groups(n=25 in each group): group A: received propofol's half-effective concentration at 3.0 μg/ml in Marsh model by TCI; group B: received propofol's half-effective concentration at 4.0 μg/ml in Marsh model by TCI. All patients were given remifentanil in Minto model by TCI after being given propofol which reached the balance between effect-site concentration and blood plasma concentration. The target concentration of remifentanil was determined by a modification of Dixon's up-and-down method. Laryngeal mask insertion was attempted after 10 mins, the insertion condition and success rate were observed, then the suitable target concentration of remifentanil(ECe50) were calculated.

50例女性乳腺良性手术患者随机分为2组（n=25），A组：靶控输注丙泊酚效应室浓度3.0 μg/ml；B组：靶控输注丙泊酚效应室浓度4.0 μg/ml（均为Marsh药代模型），待其效应室浓度和血浆浓度达平衡后给予靶控输注效应室浓度瑞芬太尼，运用Dixon's序贯法确定喉罩置入时瑞芬太尼浓度，10分钟后置入喉罩并观察喉罩置入条件与成功率，计算出相应的瑞芬太尼适宜靶浓度（ECe50值）。

A:Group1,widely opened by 20 μg·kg-1 of AD;B:Group 2,moderately opened by 10μg·kg-1 of AD;:Group 3,Slightly opened by 5μg·kg-1 of AD;D:Group 4,except a non-BBB area,pineal body,BBB was not opened in adjacent brain area by 3μg·kg-1 of AD.

a：第一组，AD 20 μg·kg-1引起的广泛开放；B：第二组，AD10 μg·kg-1引起的中度开放；C：AD 5 μg·kg-1引起的轻度开放；D：除缺乏BBB的松果体之外，AD3 μg·kg-1未引起其它脑区的BBB开放

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。

Results: No significant difference were found befween A and B or C and D group before administration of TMP. In compare with the control group, TMP might increse HR and CO but decrease BP. The most marded changes of BP and CO appeared immediately agter the administration of the drug and refurned to the same leoel as premedication 5-7min later. The ± LVdp/dtmax and Time- tenson- index decreased firstly and increased later, reached the peak at 5min. In AMI group no obvious changes was found in HR. but BP decreased and CO increased.

注药前各监测指标在A、B两组及C、D两组间均无显著性差异，与A组相比，TMP可使健康大鼠出现明显的HR增快，BP下降，以及CO的增加，BP和CO改变的最大值均出现在给药即刻，5～7分钟内逐渐恢复至给药前水平，±LVdp/dtmax和时间一张力指数为先降后升，5分钟时达最高峰；在AMI大鼠组，TMP对HR无明显改变，但出现BP下降和CO增加，对±LV dp/dt max和TTI只有短暂的抑制，l～3分钟后恢复至用药前状态，无增强作用。
