The effects of grape seed extract against toxicity of benzene on liver and kidney tissues of albino mice: biochemical evaluation / [Albino farelerde benzenin böbrek ve karaciğer dokularında toksisitesine karşı üzüm çekirdeği ekstraktının etkisi: biyokimyasal değerlendirme]

Objective: The objective of the present study was to investigate the possible effects of grape seed extract (GSE) against benzene-induced toxicity in Swiss albino mice. Methods: The animals were randomly divided into six groups each containing six mice. Group I, treated with distilled water; Group II and III orally treated with 50 mg/kg and 150 mg/kg body weight GSE, respectively. Group IV, orally treated with 250 mg/kg body weight benzene by using feeding cannula; Group V, orally treated with 50 mg/kg body weight GSE + 250 mg/kg body weight benzene; Group VI, orally treated with 150 mg/kg body weight GSE + 250 mg/kg of body weight benzene for 50 consecutive days. At the end of experimental period all mice were sacrificed; blood, liver and kidney tissues were removed after post-mortem examination. Aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine levels were analyzed from serum. Malondialdehyde (MDA) and reduced glutathione (GSH) levels were analyzed from isolated tissues. And also histopathological examinations of liver and kidney tissues were investigated. Results: Serum AST, ALT, ALP, BUN and creatinine levels were slightly increased in Group IV compared with the other tested groups (p
