Results 30～80μg/ml 23-hydroxyl betulinic acid in vitro and 300mg/kg～600mg/kg P.O.in vitro markedly inhibited the growth of B16 cells at a dose-dependent manner with a great number of apoptotic cells seen.

结果 23-羟基桦木酸体外30～80μg/ml处理，体内300mg/kg～600mg/kg灌胃时，对B16细胞有显著的生长抑制作用，有一定的剂量依赖关系并出现大量的凋亡细胞，同时体内肿瘤细胞被阻滞在G0～G1期，DNA合成受阻，肿瘤体积缩小。

Secondary pollinators are diurnal hawk moths and butterflies. Bombus briviceps and Bombus sp. are nectar gatherers. The mean nectar sugar concentration is 29.5%. The proport ion of seed is 86. 5%. Percentage seed germination under controlled conditions is 23.1 %. Distances that seeds are ejected ranged from 0.58-1.17 m. The distances that pollen spread is 29cm. Pollen viability is highest on the day of anthesis and thereafter decreased.

匍匐凤仙花的主要传粉者是蜜蜂和熊蜂，次要传粉者为白天活动的天蛾和蝴蝶，另外还有两种花蜜窃取者；花蜜糖平均浓度为29.5％；种子产生率为86.5％，种子萌发率为23.1％，种子散布距离为0.58-1.17m；花粉流为29cm；花粉活力在第一天最高，第二天次之，第三天显著减弱；P／O值为

The curve crossing probability rises gradually with the wavelength, suggesting that the conical intersection be located close to the exit channel. Br is the primary product of the photodissociation of fluorobromobenzene and bromobenzene near 266nm and it is generated through two channels.

由于势能面交叉几率随激光波长的增加有增大的趋势，我们推测势能面的交叉区域应靠近解离通道的出口。o，m，p-C6H4FBr和C6H5Br在266nm激光作用下的光解存在两种解离通道。

In the second chapter , four new tetra-O-substitution of calix[4]arene derivatives are synthesized by condensation and two steps of substitution reaction from p-tert-phenol and formaldehyde.

本文第二章对Calix[4]arene进行了功能化，通过三步反应，合成了四种新的混醚。

Microscope observations: positive staining for iNOS was observed in inflammatory cells, macrophages, kuffer cells and hepatocytes, especially at the canalicular membrane.

其中 LPS发热组3，6，gb iNOS阳性产物的整合光密度值与％阳性面积均高于正常对照组iNOS的整合光密度值和％阳性面积（P＜o.0门，且以LPS发热组6h的整合光密度值及防阳性面积为最大。

First, the effects of histidine and carnosine on ethanol-induced chronic liver injury was examined. Mice were treated four weeks by 70% ethanol p.o.

第一部份是探讨组胺酸和肌对酒精诱发之慢性肝损伤所造成的影响。

Results: The 12 kinds of toxicants including methyl acetate, ethyl acetate, benzene, toluene, ethylbenzene, butyl acetate, p-dimethylbenzene, m-dimethylbenzene, o-dimethylbenzene, n-butanol, cinnamene and cyclohexanone were separated well. Good linear relationship sensitivity and reproducibility were obtained and detection limits (S/N=3) of them were 0.2 mg/l respectively. Conclusion: In this paper, a new method for simultaneous determination of 12 kinds of toxicants by using gas chromatography has been described.

结果：对乙酸甲酯、乙酸乙酯、苯、甲苯、乙酸丁酯、乙苯、对二甲苯、间二甲苯、邻二甲苯、正丁醇、苯乙烯、环己酮12种有毒物质的分离效果好，线性和重现性均较好，方法的检测限达到0.2 mg/L。

Parameters based on chemical shift indicate that methyl is a substituent with electron-withdrawing inductive effect and poor electron-donating conjugative effect. Perhaps its conjugative effect is on critical point. Methyl is electron-withdrawing for benzene relative to H. Otherwise, methyl has strong p-position and weak o-position orientation effect.

化学位移值表示的诱导效应参数表明甲基具有吸电子诱导效应，经校正后的化学位移值表示的共轭效应参数表明甲基具有微弱的给电子共轭效应，甚至其共轭效应有可能正处于给电子和吸电子的临界状态，总之相对于氢原子，甲基具有吸电子效应。

After born, blood groups, Coomb's test, free antibody and antibody release test were done for those 286 babies who were in high risk of HDN, so that we could understand the relationship between the antibody IgG level of pregnant women and ABO-HDN....

结果：2741例O型孕妇中，IgG抗-A效价4、64、128、256和≥512各组分别占61.9%、17.0%、12.6%、6.1%和2.4%。286例母婴血型不合且有ABO-HDN危险的孕妇所生新生儿中共有71例HDN阳性，占24.8%；孕妇IgG抗-A效价为64、128、256和≥512各组HDN阳性率分别为10.7%、28.3%、44.9%和64.3%(P.01)。
