Abstract

In this study, we investigated the effects of grape seed proanthocyanidin extract (GSPE) against the side effects of high-dose administration of methylprednisolone (MP) in male rats. A total of 32 adult Wistar male albino rats were divided into four groups: (1) control (CON), received standard food only; (2) MP, received standard food + intraperitoneal injection of 60 mg/kg MP on day 7; (3) GSPE, received standard food + 200 mg/kg/day GSPE; and (4) MP + GSPE, received standard food + 200 mg/kg/day of GSPE + intraperitoneal injection of 60 mg/kg MP on day 7. All animals in the GSPE and GSPE + MP groups were treated once a day by oral gavage for 14 consecutive days. The feed intake of rats in the MP and MP + GSPE groups decreased significantly by 24.14% and 13.52%, respectively (p < 0.05). Administration of MP resulted in significant increases in serum concentrations of blood urea nitrogen (p < 0.001), glucose (p < 0.01), alkaline phosphatase, and adrenocorticotropic hormone (p < 0.05). High-dose MP administration significantly reduced catalase (p < 0.001) and glutathione peroxidase (p < 0.05) concentrations in the liver and kidney tissues of rats, while glutathione concentrations were only reduced in liver tissue (p < 0.05). The expression levels of Bcl-2 and TNF-α in liver, kidney, and testicular tissue were significantly increased, while the expression levels of caspase-3 were reduced (p < 0.001). Furthermore, sperm concentration was significantly affected by GSPE in rats induced by high-dose MP, and sperm loss was significantly reduced in MP + GSPE (p < 0.05). These findings suggest that GSPE could be useful as a supplement to alleviate MP-induced toxicity in rats.

期刊介绍: Toxicological Research is the official journal of the Korean Society of Toxicology. The journal covers all areas of Toxicological Research of chemicals, drugs and environmental agents affecting human and animals, which in turn impact public health. The journal’s mission is to disseminate scientific and technical information on diverse areas of toxicological research. Contributions by toxicologists, molecular biologists, geneticists, biochemists, pharmacologists, clinical researchers and epidemiologists with a global view on public health through toxicological research are welcome. Emphasis will be given to articles providing an understanding of the toxicological mechanisms affecting animal, human and public health. In the case of research articles using natural extracts, detailed information with respect to the origin, extraction method, chemical profiles, and characterization of standard compounds to ensure the reproducible pharmacological activity should be provided.
