Recently, it has been found that some inducers such as retinoids acid and yeast containing Se can prevent and reverse PLGC of rats to some extent. But all of these data are obtained from animal experiments, information of clinical research has not been reported. Natural β-carotin and folic acid can reverse dysplasia and intestinal metaplasia of gastric mucosa to some extent, but these effects are required to be further investigated.

晚近发现维甲酸类诱导分化剂及硒酵母对大鼠PLGC演变至胃癌有一定阻抑预防和逆转治疗作用，但均仍停留在动物实验阶段而未用之于临床；天然β-胡萝卜素和叶酸干预治疗后能一定程度地逆转胃粘膜异型增生和肠化生，值得进一步深入。

The highest enzyme producer alkalophilic Bacillus sp SHY8-1 among the inductive strains was mutagenized several times, by adding enzyme production repression aegents into screen medium, combined with natural seperation and pressure selection, finally a CMCase-hyperproductive mutant SHY8-1-25 (partitally resistant to catabolite) was obtained, with the yield of CMCase raised to 13-16u/ml, maximally reached 18-20u/ml, while its parent strain 0.654u/ml.

对诱导型产酶菌-嗜碱芽孢杆菌SHY8-1进行了多次诱变改良，采用添加产酶阻遏剂的平板作为筛子，结合反复的自然分离、压力选择，最终成功地获得了高产变异株SHY8-1-25(已部分解除分解代谢阻遏)，产酶量由0.654u/ml提高到13-16u/ml，最高达到18-20u/ml，讨论了诱变机理策略，考察了碳、氮源等对产酶的影响，对培养基和摇瓶培养条件进行了优化。

Apoptosis induced by Dex in CEM cells is associated with downregulation of the survivin expression.

结论地塞米松诱导CEM细胞凋亡与下调survivin基因表达有关。

Methods DMBA induced golden hamster cheek pouch carcinogenesis model,Resin vascular cast and prepared-Chinese-ink injection were used in this study to detect the angiogenesis of carcinogenesis.

采用DMBA诱导的金黄地鼠颊囊癌变动物模型、树脂血管灌注及墨汁血管灌注检测癌变时的血管生成情况。

Proliferating cell nuclearnatigen, bromodexoyuridine, and microscopic diagnosis were applied and observed on golden hamster cheek is pouch carcinogenisis model induced by dimethylben-zanthracene in order to seek simple ,effective ,leading and reliable diagnostic way.

为寻求简捷、高效、超前、可靠的诊断口腔粘膜癌前病变的方法，实验以DMBA诱导的金地鼠颊囊致癌模型为象，采用PCNA、BrdU核标记技术手段检测颊囊粘膜组织，并与经典的光镜观察诊断作对照。

Methods Salley′s leukoplakia carcinogenesis model of golden hamster cheek pouch is used in this study. The results are analyzed correlatively among pathological chassification, prepared-chinese-ink injection and α-smooth muscle actin immunohistochemistry.

材料与方法采用Salley法诱导金地鼠颊囊白斑癌变，以光镜下病理观察诊断分级和墨汁灌注、甲平滑肌肌动蛋白免疫组化等与血管生成有关的检测结果作相关性分析。

When the ligand 52 and 54 with only planar chirality were used the high enantioselectivity was obtained.

我们对配体平面手性作用的研究表明平面手性可以独立地进行不对称诱导，最高给出93％的ee值。

If the laser is in ultraviolet-visible wave, photons activate choicely electron energy level or destroy weak bond of compound molecule, and result in chemistry reaction, which is photo leading decomposition mechanism, if the laser is in infrared wave, the chemistry reaction mainly is heat decomposition mechanism.

如果激光是可见紫外波段，光量子能量有利于选择性地激发分子的电子能级，或破坏化合物中弱键而诱导化学反应发生，化合物属于光致分解机理、引发弱键断裂机理；如果激光是红外波段，化合物表现的则是热分解机理。

RESULTS: Different doses of cholesterin caused different degrees of apoptosis and inhibition of proliferation in HUVECS. With increasing concentration of cholesterin , the effects on HUVECs were enhanced.

结果： 不同浓度的胆固醇可不同程度地诱导HUVEC细胞发生凋亡，可明显抑制HUVEC细胞增殖，且随浓度增高，其作用均明显增强。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
