The results indicated that the water or 50% ethanol extracts from peonies petals could reduce light absorption of DPPH and OH initiated hydroxylation of salicylate, and inhibit O2(superscript -) mediated light chemical reduction of nitroblue tetrazolium effectively, and lipid peroxidation of polyunsaturated fatty from yolk lipoprotein, in which DPPH scavenging activities of 6 peonies water extracts were hinger than that of 200 μg/mL BHT, but lower than 80 μg/mL Vc. In 4 kinds of detecting systems of antioxidation, the peroxidation activity of deep colored flowers of peonies was higher than that of light colored flowers of peonies.

牡丹花瓣提取液能明显抑制卵黄组织匀浆的脂质过氧化作用，降低DPPH的吸光值、抑制O2介导的NBT光化学还原及OH作用下的水杨酸羟基化作用，其中牡丹花瓣提取液清除DPPH自由基的活性高于200μg/mL BHT，但低于80μg/mL Vc.6个品种的牡丹花瓣提取液，在4种测定系统中均具有一定程度的抗氧化能力，且水提取液的抗氧化活性略高于体积分数50%乙醇提取液，深色花瓣提取液对不同自由基的清除能力较强。

2The choosen 16mg/ml percolation filtration of Hirudo and 0.02 ug/ml PDGF were used to incubate RPE cells for 15 minutes with three different modes.

结果(1)0.02μg/mlPDGF促RPE细胞增殖作用最佳(p.05)；(2)16mg/ml水蛭渗滤液在3种加药方式下均能不同程度抑制细胞内PTK活性，降低转录因子STAT3的磷酸化水平。

Expression of osteopontin and matrix metalloproteinase-2 were detected in 40 normal placentas ,15 cases with hydatidiform moles by immunohistochemistry technique.

应用免疫组化方法分别检测正常早孕妇女绒毛40例(6周、7周、8周、9-12周各10例)、葡萄胎20例(完全性葡萄胎15例、部分性葡萄胎5例，均12周)组织中骨桥蛋白和MMP-2的表达情况，并采用病理图象分析技术进行半定量分析。

The process does not depends on catalytic hydrogenization method, has simple reaction condition, high reactant yield all over 75%, can use TLC to track the whole reaction process, and is more suitable to the transformation of function group in the organic synthesis field as the result of N-Boc or N-Cbz derivative is easy to loss protective reaction, which has spreading application prospect.

该方法不依赖于催化氢化方法，反应条件简单，反应产物产率高，均在75％以上，反应过程可用TLC进行跟踪，且由于N-Boc或N-Cbz衍生物更易发生去保护反应，在有机合成领域更适宜于官能团的转化，具有广阔的应用前景。

All these experimental results lay a foundation for cleaning hydrolyzation technology.

这些工艺研究的结果，均为水解工艺的清洁化提供了依据。

Mutant libraries created by saturation mutagenesis of each single amino acid site D168, A225, K434 and E435 were screened to further improve the capability of cytochrome P450 BM-3(A74G/F87V/L188Q) mutant from Bacillus Megaterium which can hydroxylate indole into indigo. Results showed that D168, K434 and E435 are located at the functional domain of P450 BM-3 protein while A225 is sited at the unfunctional domain.

为了进一步获得具有更高活力的细胞色素P450 BM-3(F87V/A74G/L188Q)突变酶，利用饱和突变技术对该突变酶的4个氨基酸位点D168、A225、K434、E435分别进行单一的随机突变，通过对其羟基化吲哚生成靛蓝的催化性能表征，发现P450 BM-3氨基酸残基的168、434和435位均位于蛋白功能区域，而225位则位于非功能区域。

With the deflected succession of aquatic ecotype plant functional group,the dominance of mesophytes and xerophytes increased,while the dominance of aquatic and hygric plants decreased. However,there are only planting crops in the reclaimed wetland. In the composition of plant biotype functional group,the hydrophytes reduced quickly with the deflected succession and the dominance of perennial herbs is mostly marked,and there are only annual herbs in reclaimed wetland. Compared with primary swamp,the species diversity index of meadow is the highest,the swampy meadow follows,and the reclaimed wetland is the lowest.

植物的水分生态型功能群组成随湿地的逆行演替，水生、湿生类植物功能群的优势度不断减少，中生、旱生类植物功能群的优势度逐步增加，而在垦后湿地只有农作物；植物生活型功能群组成随湿地的逆行演替，水生草本迅速减少，陆生多年生草本增加占据优势，而在垦后湿地均为一年生草本；湿地植物物种丰富度、多样性指数由原生沼泽、沼泽化草甸到草甸依次增加，草甸为最大值，而垦后湿地则最低。

In the present study, the expression of bFGF and TGF β1 in normal and hyperplasic prostate were determined with immunohistochemistry and in situ hybridization.

本研究采用免疫组化及原位杂交方法检测bFGF和TGF-β1在正常前列腺及BPH中的表达情况，结果显示，正常及增生前列腺组织中上皮及间质细胞中均见bFGF、bFGFmRNA及TGF-β_1、TGF-β_1mRNA阳性染色，间质细胞染色强于上皮细胞。

Results: The normal epithelial cells were intactly lined with microvilli, and lesions on the surface of Ct infected cells were showed by SEM. The expression of actin was obvious throughout the cytoplasm of uterine epithelial cells but appeared to be most intense along the apical plasma membrane on day 4, 5 and 6 of pregnancy. On the day 7, levels of actin had increased along the apical surface. The expression of actin in the infected group was weaker than that in of the normal group.
