Changes in albumin and antioxidant enzyme mRNA expression in infant rat liver following administration of total parenteral nutrition (TPN) with/without soybean oil emulsion were studied. Infant rats were divided into three groups: group 1=oral diet, group 2=TPN without fat, and group 3=TPN with 20% of calories from soybean oil emulsion. The period of TPN administration was 4 d. Serum aspartate aminotransferase and alanine aminotransferase levels were higher in group 2 than in the other groups, with similar levels seen in the other groups. Albumin, Cu, Zn-superoxide dismutase, and glutaredoxin 1 mRNA expression levels were lower in group 2 than in the other groups, with similar levels seen in the other groups. Catalase mRNA expression was higher in group 1 than in the other groups, with the lowest level seen in group 2. Soybean oil emulsion should be included in TPN regimens to prevent down-regulation of albumin and antioxidant enzyme mRNA expression.

Free radicals have been implicated in the pathogenesis of neonatal septicemia. The present study was planned to estimate the lipid peroxidation and antioxidant status in neonatal septicemia. The study was done to evaluate the lipid peroxidation and antioxidant status, both enzymatic and non-enzymatic in neonates with septicemia. This prospective study included 44 septicemic babies as cases and a group of 84 matched healthy babies formed the control. Malondialdehyde (MDA), Superoxide dismutase (SOD), Glutathione peroxidase (GTPx), Catalase, Uric acid (UA) and Albumin (Alb) were estimated in the serum and compared between the groups. The statistical analysis was done by using SPSS-10 software. Neonates with septicemia had significantly higher levels of MDA, SOD, GTPx, and Catalase, while the levels of UA and Alb were significantly lower as compared to controls (p<0.001). Significantly elevated levels of MDA (p<0.05) and depressed levels of UA (p<0.001) were found in babies with late onset sepsis. Neonates who ultimately succumbed had significantly elevated levels of MDA, SOD, GTPx and Catalase, whereas levels of UA and Alb were significantly depressed (p<0.001). Neonates with sepsis are handicapped in terms of their defense mechanism against free radicals. The utility of supplementation of antioxidant enzymes in neonates with septicemia needs further evaluation.

Present study deals with the hepatoprotective activity of polyherbal formulation Hepatoplus (HP) as an oral supplement to the INH and RIF induced hepatitis in experimental rats. Rats treated with INH and RIF show abnormal liver function with significant increase in serum transaminases, bilirubin and clotting time (CT) and significant decrease in total protein and Albumin, which is brings to near normal levels by HP and LIV 52 treatments. Rats treated with INH and RIF suffer from oxidative stress in the hepatocytes, due to the decrease in Glutathione (GSH), Glutathione peroxidase (GPX), Catalase (CAT), Super oxide dismutase (SOD) and significant increase in Lipid Per oxidation (LPO). HP decreases the oxidative stress and protects the liver cells membrane from LPO. 85% of DNA damage (comet tail) seen with RIF and INH treatment is reduced to 34.1% on HP application. A decrease of hepatocytes mitochondrial dehydrogenase activity is observed in INH and RIF treatment is restored by HP supplementation. Hepatic apoptotic and CYP2E1 gene expressions were also studied, BAX, p53, Caspase 3 and CYP2E1 were significantly up regulated and Bcl2 was down- regulated in INH and RIF treated rats. Concomitant application of HP prevents the modulation of these gene expressions. It is concluded that high dose of HP (100mg/kg) supplemented along with INH and RIF effectively prevents the toxicity induced by INH and RIF, as effective as 100mg/kg of LIV52.
