The combined effect of gallic acid (3,4,5-trihydroxy benzoic acid;GA;50 mg kg^(-1) i.p.) and propolis (200 mg kg^(-1)p.o.)was evaluated against beryllium-induced biochemical and morphological alterations in the liver and kidney. Femalealbino rats were exposed to beryllium nitrate (1 mg kg^(-1)i.p.) daily for 28 days followed by treatment with the abovementioned therapeutic agents either individually or in combination for five consecutive days. Exposure to berylliumincreased its concentration in the serum, liver and kidney and caused significant alterations in cytochrome P450enzymes, microsomal lipid peroxidation and protein contents. Beryllium administration significantly altered theaspartate aminotransaminase, alanine aminotransaminase, lactate dehydrogenase, -glutamyl transpeptidase,bilirubin, creatinine and urea in serum, and the activity of acid phosphatase, alkaline phosphatase, adenosinetriphosphatase, glucose-6-phophatase and succinic dehydrogenase, triglycerides, cholesterol, protein contents,glycogen contents, lipid peroxidation and glutathione level in the liver and kidney. Beryllium exposure inducedsevere alterations in hepatorenal morphology, revealing its toxic consequences at a cellular level. Individual administrationof GA and propolis reduced the effects on the studied parameters to a degree. Interestingly, GA in conjunctionwith propolis reversed the alterations in all of the variables examined, highlighting the beneficial effects ofcombined therapy over monotherapy in the alleviation of beryllium-induced systemic toxicity.

To evaluate hepatic injury induced by antituberculosis drugs(ATDs) when administered orally for 2, 4, 6 and 8 weeks and the therapeutic potential of propolis(bee hive product) against ATDs induced hepatic injury. Methods: The ATDs were administered for 8 weeks as well as propolis extract at three different doses(100, 200, 400 mg/kg) conjointly for 8 weeks in rats. Silymarin(50 mg/kg) was given as positive control. Animals were euthanized after 8 weeks; blood and liver samples were collected to perform various biochemicals, serological and histopathological and ultramorphological studies. Results: Significant increase(P < 0.05) in aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triglyceride and cholesterol along with reduction in glucose and albumin level were noted after ATDs induced hepatic injury. Significant increase(P < 0.05) in lipid peroxidation, triglyceride, cholesterol and CYP2E1 activity; decline in reduced glutathione, catalase, superoxide dismutase, glutathione reductase, glutathione peroxidase, glucose-6-phosphatase dehydrogenase activity were observed after ATDs intoxication. Due to presence of a wide range of flavonoids and polyphenols in propolis extract, its administration reduced hepatic injury and maintained biochemical indices towards control. Histopathological and electron microscopic observations indicated hepatoprotective potential of propolis at cellular level whereas, TNF-α, IL-6 and IGF-1 confirmed therapeutic potential of propolis at molecular level. Conclusions: It can be concluded that propolis possess hepatoprotective potential against ATDs induced hepatic injury that may prove itself as a clinically useful natural product in management of drug induced liver injury.

＜正＞ The purpose of this investigation was to explore whether or not propolis extract could prevent the hepatic damage caused by model toxicant i.e. carbon tetrachloride（CCl4）. Antioxidative efficacy of propolis extract was evaluated against acute （1.5 ml/kg, ip. once only） and subchronic （0.15 ml/kg, ip. 21 days） exposure to CCl4. Toxicant exposure provoked marked elevation in the activities of serum transaminases. alkaline phosphatase and lactate dehydrogenase. Significant increased lipid peroxidation was observed after toxicant exposure. Drastic alterations were observed in enzymatic and non - enzymatic antioxidant defense system, which were estimated by reduced and oxidised glutathione. glutathione peroxidaseand glutathione reductase in liver. Initial screening of Propolis extract at different doses （50. 100. 200 and 400 mg/kg. once only, po） revealed recoupment in acute study and found to be very effective in restoring all the parameters. Treatment with effective dose of Propolis extract （200 mg/kg. po） for 5 days after subchronic exposure of toxicant caused significant recovery. It was observed that Propolis exerts its beneficial hepatoprotective effect as a natural antioxidant due to the presence of polyphenols and flavonoids.
