The aim of the present study was to evaluate the effect of troxerutin (TXN) on Nickel (Ni) toxicity by using rats and in vitro model. Ni toxicity induced in male albino wistar rats (20 mg/kg body weight (b.w) was administered orally for 20 days). TXN was administered orally (100 mg/kg (b.w) for 20 days with administration of Ni. The toxic effect of Ni and the action of TXN was measure by determ...

The aim of the study was to evaluate the antioxidant and free radical scavenging properties and to determine the phenolic content of the ethanol extract from five Mentha species [M. longifolia (L.) Huds., M. piperita L., M. pulegium L., M. rotundifolia (L.) Huds., and M. spicata L.]. The antioxidant activities of the extracts were investigated with two different methods, 2,2’-diphenyl-1-picrylh...

Heme oxygenase-1 (HO-1) catalyzes the rate-limiting step in heme catabolism and presumably is involved in cellular iron homeostasis. It is induced by a variety of cellular stresses, including oxygen deprivation and free radical-mediated stress. We examined induction of HO-1 mRNA in skin fibroblasts and investigated the mechanism by which it occurs. Hypoxia did not appear to act via induction of...

Tetrabromobisphenol A (TBBPA) is a widely used brominated flame retardant, applied in a variety of commercial and household products, mainly electronic ones. Since the production of reactive oxygen species (ROS) is considered one of the principal cytotoxicity mechanisms, numerous studies undertake that aspect of TBBPA's mechanism of action. The present study verifies if the fluorogenic substrat...

Photosensitive dyes representative of the thiazines, xanthenes, acridines, and phenazines mediated phototoxicity in Escherichia coli B. The observed phototoxicity was sensitizer-, light-, and oxygen-dependent and is therefore a photodynamic effect. Hydroxyl radical scavengers conferred protection against the photodynamic action of all of the representative dyes. The extent of protection was dep...
