Background: Recent studies have revealed that oocyte competence can be assessed through the presence of the glucose-6-phosphate dehydrogenase (G6PDH) enzyme, as indicated by brilliant cresyl blue (BCB), a dye that can be degraded by G6PDH. In the present study, we aimed to examine the validity of BCB test to select developmentally competent oocyte in ovine and its association with stage-specifi...

calendula officinalis (family compositae) flowers are recognized as safe substance for food use by food and drug administration. present study was aimed to determine the modulatory effect of floral extracts of c. officinalis administrations on mean blood glucose (mbg), per cent glycosylated hemoglobin (hba1c), lipid profile [(total cholesterol (tc), triglycerides (tg), low and high density lipo...

Two groups of adult male rats 8 weeks old were fed a 10 p. 100 protein (casein) diet with or without 2 p. 100 methionine. After 8 rats in each group were killed at 10 a.m. on experimental days 1, 2, 4, 8 and 21, we studied the profiles of plasma non-esterified fatty acids (NEFA) and of the hepatic activities of pyruvate kinase (PK), phosphoenolpyruvate carboxykinase (PEPCK), glucose-6-phosphate...

PURPOSE Investigate the effects of a single electroacupuncture (EA) session at acupoints Zusanli (ST-36) and Zhongwan (CV-12) combined in regulating oxidative stress in liver and kidney in anesthetized rats. METHODS Eighteen healthy rats randomly assigned to 3 groups (n=6) were anesthetized intraperitoneally with ketamine (90 mg kg-1 body weight) + xylazine (10mg/kg body weight): G-1: Control...

The effects of oxygen on the quantitative histochemical assay to detect glucose-6-phosphate dehydrogenase (G6PDH) activity based on neotetrazolium reduction were studied in the different stages of carcinogenesis in the colon. Normal and hyperplastic epithelium, mucosae of patients with active Crohn's disease, and adenomas and adenocarcinomas of the colon were used. Epithelium of normal and infl...

The present study was conducted to evaluate the therapeutic efficacy of Rhinacanthus nasutus (R. nasutus) on mitochondrial and cytosolic enzymes in streptozotocin-induced diabetic rats. The rats were divided into five groups with 6 rats in each group. The methanolic extract of R. nasutus was orally administered at a dose of 200 mg/kg/day, and glibenclamide was administered at a dose of 50 mg/kg...

The activity of cholinesterase (ChE), glutathione-S transferase (GST), glutathione reductase (GR), glucose-6-phosphate dehydrogenase (G6PDH) and catalase (CAT) was evaluated in the gill and digestive glands of the Perna perna mussel transplanted to three non-contaminated mariculture zones under the influence of distinct physical-chemical characteristics. Differences among sites for ChE, GST and...

Effect of polyherbal formulation Ambrex was evaluated in butylated hydroxytoluene (BHT) induced toxicity of lungs and liver in rats. Toxicity was produced by administering BHT (500 mg/kg/day) for 3 days. Lung damage was evidenced by elevated levels of broncho alveolar lavage fluid (BAL) parameters such as protein, lactate, lactate dehydrogenase (LDH), alkaline phosphatase (ALP), acid phosphatas...

Little is known of the normal seasonal variation in redox state and biotransformation activities in birds. In long-distance migratory birds, in particular, seasonal changes could be expected to occur because of the demands of migration and reproduction. In this study, we measured several redox parameters in the barn swallow (Hirundo rustica L.) during the annual cycle. We captured the wintering...
