The guinea pigs were dermally exposed to nickel (Ni), sodium lauryl sulphate (SLS) and in their combination for 7 and 14 days. The exposure to Ni and SLS produced changes in enzymes and lipid peroxidation in kidney. The exposure to Ni or SLS depicted slight changes while combined exposure to Ni plus SLS exhibited more degenerative changes in kidney. The result of the study suggests that industrial workers and/or populations exposed simultaneously to Ni and SLS produces more damage to kidney. 展开更多

The guinea pigs were dermally exposed to paraphenylenediamine (PPD) and in presence of an oxidising agent hydrogen peroxide for 15 and 30 d to assess their effects on some enzymes, lipid peroxidation and histamine contents in the skin. The activities of acid and alkaline phosphatases, β-glucuronidase, gamma glutamyl transpeptidase, histidase and tyrosinase were enhanced after application of either PPD or PPD plus hydrogen peroxide. The lipid peroxidation and histamine contents also showed marked elevation following exposure to the chemicals. 展开更多

印度一项反刍动物营养研究表明,水(瘤)牛以秸秆为主并饲以尿素、糖蜜、矿物质作为添加剂,极有利于增加秸秆消化率及其随意采食量。但是,由于某些限制因素,诸如糖蜜不易获得,和由于这些添加剂是现拌现用,农民日复一日地将这种添加剂喷洒... 印度一项反刍动物营养研究表明,水(瘤)牛以秸秆为主并饲以尿素、糖蜜、矿物质作为添加剂,极有利于增加秸秆消化率及其随意采食量。但是,由于某些限制因素,诸如糖蜜不易获得,和由于这些添加剂是现拌现用,农民日复一日地将这种添加剂喷洒在秸秆上,很费劳力,在印度农村条件下有碍人们使用这项有用的技术。围绕上述问题,最近阿南德(Anand) 展开更多
