AIM: To find out the effect of Cat’s whiskers (Cleome gynandra L., Capparidaceae) flavonoid (CWF) for the scavenging of free radicals in some inflammatory cells. METHODS: Mouse erythrocyte’s hemoglobin, peritoneal macrophage, and peripheral blood lymphocytes were oxidized either by some of toxic chemicals (nitrite, carbon tetrachloride) or by enzymatic stimulation (glu- coseoxidase) to produce oxidative damage to cells. The protective effect of the CWF was examined, and the biochemical mechanism of action was also investigated in terms of the scavenging of free radicals. RESULTS: CWF (1 20 μg mL 1 ) decreased glucoseoxidase and nitrite induce oxidative damage in a concentration dependent manner in an in vitro model and inhibited the lysis of RBC [(28.64 ± 13.03)% and (70.31 ± 1.80)%] when mice were treated with CWF (25 and 50 mg kg 1 ). To assess the antioxidant potential of CWF in the lymphocytes and macrophages in living animals, the effect of CWF was measured on the elevated level of superoxide anions production in the cells. CWF scavenged the superoxide anion (O 2 ) production and inhibited the O 2 induced destruction of protein and lipid biomolecules. CONCLUSION: The study has established that the CWF mediates its antioxidant activity in some chronic inflammatory cells via its free radical scavenging activity.

外国公司亦难幸免    从中国反腐败的势头来看,是动真格的了,几千名官员被起诉,枪毙的也从一位数变为两位数。从趋势来看,北京当局当然不会不注意到,腐败分子所以屡禁不止,一是有后台,二是有人喜欢通过行贿的方法来办事。那么,下一阶段,不但要抓受贿的,也要把行贿的送上法庭,这是早晚的事。  这样一来,势必牵涉到在中国做生意的部分外国公司,尤其是一些神通广大的公司。在这个问题上,有些西方公司是自相矛盾的。

雨后空气中那种清新气味是怎么来的?一方面是部分植物在长期的干旱和阳光照射下分泌的芳香油,另一方面是干燥的石块和土坷垃中累积的化合物。  土臭素是其中最为重要的一种,在潮湿且植被丰富地区的土壤中含量尤其高。它是土壤里一种放线菌生产孢子时的副产物,基本可以算是泥土气味的主要来源。  人的嗅觉对土臭素极其敏感,有些人甚至在浓度仅为 5万亿分之一时就能感知到其存在。  那雨滴是如何将这些化合物散播到空气中
