RESULTS: At 16 weeks after the compound of after-induced chondrogenetic BMSCs and SIS were transplanted, the materials had been completely absorbed and there were new cambium in the experimental group, which proved to be chondrocytes after hematoxylin-eosin stain, Massan stain and Toluidine blue dyeing.

结果：诱导软骨细胞-小肠黏膜下层复合物在植入体内16周时材料明显被吸收完全，且有软骨生成，与正常组织未见明显区别，但修复层软骨较薄。经苏木精-伊红染色，Massan染色，甲苯胺蓝染色检查证实为软骨组织。

Results: IL-8 protein was located in the epithelium of viii. The expression of IL-8 was significantly increased in RSA group than that in the control group. Positive IL-8 cells was shown in decidua of RSA group, and its IL-8 level was higher than that in the control group. By hematoxylin-eosin staining. trophoblastic layer was found to get thinner, cells of trophoblastic layer denatured or necrotized, and turned acidophily, and the fibration of villous axis increased in RSA; decidual cells lost connection, a part of decidual cells appeared cytoclasis and turned more acidophilic, and nuclei disappeared in RSA.

结果：在绒毛组织中，IL-8蛋白定位于绒毛上皮细胞的细胞质内，且病例组的表达明显高于对照组；在蜕膜组织中；病例组蜕膜细胞的胞质内可见IL-8蛋白表达，且高于对照组；H-E染色可见病例组绒毛组织的滋养层变薄，细胞变性甚至坏死、嗜酸性增强，绒毛中轴纤维化程度增强；蜕膜组织中蜕膜细胞失去细胞间连接，部分蜕膜细胞解体、核消失。

At dampy climate or after rain, there is a very thin water film on tyre tread or road surface, which causes motor vehicle tractive force reduction during driving.

Methods Five different ultraviolet absorption components were isolated from the filtrate of Botrytis cinerea isolate 7–3 culture. Of the five components, one showed strong inhibitory to Digitaria sanguinalis.

在前期薄层层析法、柱层析法和高效液相色谱法分析的基础上对灰葡萄孢诱变菌株BC7–3的代谢产物中具有除草活性的5个不同组分分别进行了液相色谱制备。

The antimicrobial test and researched was done on wide distillation of different solvents on Terpenoid, polarity separation of ethanol distillable substance, thin layer chromatography of different polarities and distillation of amylase. The results showed that the active substance distilled by 95% ethanol and V methanol: toluene=3:1 had stronger antimicrobial activity on Agaricus blazei Murrill. The antimicrobial activity of ethyl acetate was stronger than wide distilling substance with ethanol, but the water part has not antimicrobial effect. Two straps of ethyl acetate phase（Rf0.57、Rf0.63）(0.1g/ml)had stronger antimicrobial activity on Agaricus blazei Murrill, the antimicrobial zone on Pseudomonas was 19.3mm. The bacteriostatic activity of chromatography strap of water phase was rather weaker, the water solution (0.5g/g) of amylase had better effect on pathogenic fungus of Agaricus blazei Murrill, its antimicrobial zone on Aspergillus niger, Citrinin, Trichoderma viride were 10.8 mm, 7.9 mm, 5.3 mm.

通过对日本凹顶藻以不同溶剂的粗提、乙醇提取物的极性分离、不同极性的薄层层析和多糖的提取，进行抗菌试验的研究，发现95%乙醇和V甲醇：甲苯为3∶1的提取的活性物质具有较强的抗姬松茸的病原细菌活性，乙酸乙酯相对病原细菌的抑菌强于乙醇的粗提物，而水相基本无抑菌效果，乙酸乙酯相的两个带（Rf0.57、Rf0.63）浓度为0.1g/ml具有较强抗姬松茸病原细菌的活性，对假单孢杆菌抑菌圈达到19.3mm，水相层析带的抑菌活性较弱，多糖的粗提物配成0.25g/g的水溶液对姬松茸病原真菌有较好的抑菌效果对黑曲霉、桔青霉和绿色木霉的抑菌圈分别达到10.8 mm、7.9 mm、5.3 mm。

The antifungal activities of these materials were investigated and build foundation to develop low poison plant antifungal products. In experiment, polyphenols were extracted by reflux ectraction method which applyed petroleum ether to degrease and methyl alcohol solvent. Phenolic hydroxyl were examined and inspected by colour-developing reaction and the content of total polyphenols was determined by UV-spectrophotometry. Screening test were performed to the antifungal activities of polyphenol extraction by the tube dilution method to the selected ten pathogenic fungus such as Dothiorella gregaria, Rhizoctonia solani, Phyllosticta pirina, and the minimal inhibitory concentration were measured. The column chromatography and thin layer chromatography were applyed to separate and analyse cortex extracts of Dracaena cochinchinensi Lour.
