Diels (contains ligustilide ＞ 70%), could markedly inhibit the contractile function of isolated uterine smooth muscle of mice in a concentration-dependent manner (the utlimate bath concentration is 1 mg/100 mL～32 mg/100 mL) whether the test sample was isolated from normal or oxytocin treated mice. It proved that angelica oil had significant anticonvulsive effect in uterine smooth muscle of mice.

当归油 (含藁本内酯 ligustilide＞70%)，用1%吐温-80助溶，无论对正常未孕离体子宫还是对经缩宫素处理的离体子宫，都可剂量依赖性(浴槽终浓度为 1 mg/100 mL～32 mg/100 mL)地抑制子宫平滑肌的收缩功能，其性质与妇痛宁滴丸相似，但作用稍强，表明其有抗子宫平滑肌痉挛作用。

Thus the sample size can be increased, and the nugget effect and detection limits can be decreased compared with normal Carius tube technique. This new technique is capable of digesting 12 g samples in a 75 mL Carius tube with 35 mL aqua regia at 320℃, and Re and all the PGEs can be measured.

由此可以加大取样量，降低铂族元素测定过程中的块金效应及检出限，使超低含量铂族元素的测定成为可能。12g样品在75mL卡洛斯管中用35mL王水于320℃溶解15h，基本上可以使各种地质样品中的铂族元素矿物完全溶解。

M{rX*o0 OBJECTIVE: To investigate the effects of neuronal nitric oxide synthase inhibitor 7-nitroindazole (7-NI) on smoke inhalation pulmonary injury in rats. METHODS: Forty healthy male SD rats were randomly divided into three groups: control group (n=8), smoke inhalation model group (n=16) and 7-NI treatment group (n=16). After reproducing the smoke inhalation model, to the 7-NI treatment group rats 7-NI (20 mg/kg in 2 ml arachis oil) was administered by intraperitoneal injection, while in the control group and the model group, 2 ml arachis oil was administered by intraperitoneal injection.

(1) to deliver the Levonorgestrel (0.ml/kg,5mg/m) and Mifepristone gelatum (0.1ml/kg,5mg/ml) per cutem to the rat respectively and measure the serum concentration of levonorgestrel、mifepristone、estradiol and progesterone at different time by the means of HPLC, radioimmunoassay,chemical separation and atomic absorption spectrophotome.

大鼠皮肤涂抹米非司酮凝胶(0.1ml/kg，5mg/ml)和左炔诺孕酮凝胶(0.1ml/kg，1mg/ml)后的不同时间，利用高效液相色谱法、放射免疫分析法、化学分离与原子吸收分光光度法，测量血清中米非司酮浓度、左炔诺孕酮凝胶以及血清雌二醇、孕酮浓度。

C. gigantea is a high biomass, fast growing perennial shrub growing as a weed in the Hainan province of China. It was used as a traditional folk medicine for the treatment of cough, leprosy, and asthma by the people of Li nationality, who are autochthon of Hainan island of China. In our screening for bioactive agents from tropical medicinal plants, the ethanol extract of the roots of C. gigantea showed cytotoxic activity towards human chronic myelogenous leukemia (K562) and human gastric cancer (SGC-7901) cell lines in vitro by MTT method with IC50 values of 9.7 μg/mL and 6.7 μg/mL, respectively.

为了开发热带药用植物资源，从中寻找具有药用价值的生物活性成分，本文采用MTT法对牛角瓜乙醇提取物进行体外活性筛选，结果表明其对K562 及SGC-7901 具有细胞毒活性，IC50值分别为9.7 μg/mL 和 6.7 μg/mL。
