Cisplatin causes chronic interstitial disease with fibrosis, but the development mechanism of interstitial fibrosis is not yet understood. We examined the effect of an antioxidant, N,N'-diphenyl-1,4-phenylenediamine (DPPD), on development of interstitial fibrosis induced by cisplatin. Cisplatin increased blood urea nitrogen

This study was undertaken in order to examine the roles of lipid peroxidation and poly (ADP-ribose) polymerase (PARP) activation in oxidant-induced renal cell death. Opossum kidney cell cultures were used as the renal epithelial cell model, and an inorganic hydroperoxide

The oxidation of N,N'-diphenyl-1,4-phenylenediamine (DPPD) has been studied by cyclic voltammetry at glassy carbon electrodes in propylene carbonate. Next, the reaction between ammonia and DPPD was similarly investigated. It has been shown that ammonia reversibly removes protons from oxidized DPPD

Tuberculosis (Edinburgh, Scotland), 81(5-6), 353-358 (2002-01-22)
Although the tuberculin test has aided in the diagnosis of tuberculosis for more than 85 years, its interpretation is difficult particularly because sensitization with non-tuberculous mycobacteria leads to false positive tests. Using the guinea pig model of tuberculosis, we have
