Abstract

The aim of this study was to investigate whether (E)-2-benzylidene-4-phenyl-1, 3-diselenole (BPD) protects against hepatotoxicity induced by thioacetamide (TAA). On the first day of treatment, male adult Wistar rats received BPD (10 or 50 mg x [kg.sup.-1]). On the second day, the rats received a single intraperitoneal injection of TAA (400 mg x [kg.sup.-1]). Twenty-four hours after TAA administration, biochemical determinations and liver histological analysis were carried out. BPD (50 mg x [kg.sup.-1]) reduced plasma aspartate and alanine aminotransferase, alkaline phosphatase, and lactate dehydrogenase activities increased by TAA exposure. Treatment with BPD was effective against increased lipid peroxidation levels and attenuated a decrease in hepatic reduced glutathione and ascorbic acid levels as well as an inhibition of glutathione peroxidase activity caused by TAA exposure. The higher dose of BPD protected against the inhibition of hepatic [delta]-aminolevulinic dehydratase activity induced by TAA. Finally, histopathological examination of the liver showed that BPD markedly ameliorated TAA-induced hepatic injury. In conclusion, BPD protected against hepatotoxicity and oxidative stress caused by TAA exposure in rats. Key words: selenium, thioacetamide, oxidative stress, liver, antioxidant. Ces travaux avaient pour but d'etudier si le (E)-2-benzylidene-4-phenyl-1, 3-diselenole (BPD) assure une protection contre l'hepatotoxicite provoquee par le thioacetamide (TAA). Des rats Wistar males adultes ont recu du BPD (10 ou 50 mg x [kg.sup.-1]) le premier jour du traitement. Le deuxieme jour, les rats ont recu une injection intraperitoneale unique de TAA (400 mg x [kg.sup.-1]). Nous avons procede a des analyses biochimiques et a l'examen histologique du foie 24 heures apres l'administration de TAA. Le BPD (50 mg x [kg.sup.-1]) permettait d'attenuer les augmentations de l'activite de l'aspartate et de l'alanine aminotransferase, de la phosphatase alcaline et de la deshydrogenase lactique causees par l'exposition au TAA. Le traitement par le BPD etait efficace contre l'augmentation des taux de peroxydation lipidique et attenuait la diminution des taux de glutathion reduit et d'acide ascorbique ainsi que l'inhibition de l'activite de la glutathion peroxydase causees par l'exposition au TAA. La dose de BPD la plus elevee assurait une protection contre l'inhibition de l'activite de la deshydratase [delta]-aminolevulinique hepatique provoquee par le TAA. Enfin, l'examen histopathologique du foie montrait que le BPD permettait d'attenuer de facon marquee les lesions hepatiques provoquees par le TAA. En conclusion, le BPD assurait une protection contre l'hepatotoxicite et le stress oxydatif causes par l'exposition au TAA chez le rat.

Nevertheless, it is susceptible to damage from a number of drugs and toxins (Lee 2003). Rodent [...]
