  • Dichlorodiphenyltrichloroethane (DDT) is a widespread environmental pollutant. Earlier reports have demonstrated that DDT is an endocrine-active compound capable of affecting early-stage sexual differentiation in male rats. Experiments based on receptor binding affinity and receptor-mediated transcriptional activation have identified DDE as an androgen receptor antagonist.(omitted)

  • This study considers Huewa悔窩 Anjung-gwan安重觀's self-consciousness and the recognition of the world. Anjung-gwan resents that fact that Qing淸 rules over China. He insists that Chosun朝鮮 must remain faithful to Ming明. But Chosun served Qing in those days. He holds strongly to his belief until his death. So he chooses living in retirement in his life. In Anjung-gwan's poems, we can see that a certain circle of Chosun Confucianists believe in Sojunghwa小中華, which is small-Sinocentrism. In the first half of the eighteenth-century, some Chosun Confucianists feel sad about the situation that stops them from realizing their ideals. But they take pride in natural beauty and configuration of Chosun. And they pay attention to the life of Chosun masses. They recognize Chosun, which is Hwa華, has to keep self-respect to the last.

  • A thrombus is a mass formed from the constituents of the blood within the vessels or the heart during life. The process of formation is known as thrombosis. A vegetable warms producing fibrinolytic enzyme was isolated from chines traditional medicinal mushrooms. Cordyceps militairs and Paecilomyces tenuipes. The fibrinolytic enzyme of Cordyceps militaris and Paecilomyces tenuipes was purified from fruiting body by -70 prechilled ethanol precipitation. ion-exchange chromatography. gel filtration.

  • Synthetic polymers, biological polymer such as collagen and gelatin are employed extensively as backbones in the construction of hydrogels or cell/tissue scaffoldings for various biomedical applications. In the present study, we investigated the effect of collagen and gelatin on the inducible nitric oxide synthase (iNOS) gene expression in the mouse macrophage cell line RAW 264.7. The production of nitric oxide and expression level of iNOS mRNA were induced by both of collagen and gelatin in dose-dependent manner. (omitted)

  • Actinomycetes CS0707 has been isolated in soil sample from location in the Jeju province. Korea, and produces thermostable extracellular proteases. Actinomycetes CS0703 showed the highest protease activity at late exponential phase when grown in OSYM medium (oatmeal 2.0%, soybean meal 1 %, dried yeast 1 %, mannitol 1 %) at $48^{\circ}C$. Three forms of protease(Ta-1, TA-2 and Ta-3) were fractionated by Ultrogel AcA 54 column chromatography, and further purified through ammonium sulfate fractionation, ultramembrane filtration, and DEAE-sepharose CL-6B column chromatography.
