  • Objectives The present subacute study was designed to evaluate the effect of coenzyme Q 10 (CoQ10) in the 28 days aroclor 1254 exposure induced oxidative stress in mice brain. Methods Biochemical estimations of brain lipid peroxidation (LPO), reduced glutathione (GSH), and activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and acetyl cholinesterase (AChE), and histopathological investigations of brain tissue were carried out. Results Oral exposure of aroclor 1254 (5 mg/kg) led to significant decrease in levels of GSH, and activities of SOD, CAT, GPx, and AChE, and increase in LPO. These aberrations were restored by CoQ10 (10 mg/kg, intraperitoneal injection [IP]). This protection offered was comparable to that of L-deprenyl (1 mg/kg, IP) which served as a reference standard. Conclusions Aroclor 1254 exposure hampers the activities of various antioxidant enzymes and induces oxidative stress in the brains of Swiss albino mice. Supplementation of CoQ10 abrogates these deleterious effects of aroclor 1254. CoQ10 also apparently enhanced acetyl cholinesterase activity which reflects its influence on the cholinergic system.

  • Modem people have begun to have the nationwide interest in the rice wine called Makgeolri which is one of the traditional Korean alcoholic liquors. This study was performed to investigate the effects of San sung Makgeolri extract (SM) on antioxidation together with the determination of pH and dissolved oxygen (DO) in the progress of fermentation in the lipopolysaccharide(LPS)-treated rats. We examined the levels of SOD (superoxide dismutase), CAT (catalase), GPx (glutathione peroxidase) in liver homogenates and the histopathological observations in liver tissue. LPS-treated group markedly decreased the levels of SOD, CAT and GPx. But SM + LPS-treated group significantly increased the levels of them. Furthermore, the antioxidative effects of SM were supported by the histopathological observations in liver tissue which showed severe inflammation and necrosis in LPS-treated group, compared to the attenuated inflammation and necrosis in SM + LPS-treated group. This results suggested that SM could be a candidate of antioxidative material in spite of alcoholic liquors.

  • This study was carried out to investigate the effect of natural Eriobotrya japonica Lindl. vinegar on the liver protective effect of animals exposed to carbon tetrachloride. Eriobotrya japonica Lindl. vinegar (200 mg/kg) was administered at the same time for 28 days, and hepatotoxicity was induced by intraperitoneal injection of carbon tetrachloride on the $29^{th}$ day. The aspartate aminotransferase and alanine aminotransferase levels were significantly decreased (p < 0.001) and the superoxide dismutase and catalase activities were significantly increased (p < 0.001) in the Eriobotrya japonica Lindl. vinegar group compared to the control group. Histopathological observations showed that the Eriobotrya japonica Lindl. vinegar showed hepatic cell structure similar to normal group, and these results showed that it had an effect of suppressing and protecting the damage of liver cell. Therefore, Eriobotrya japonical Lindl. vinegar is considered to be a healthy functional food of the liver.
