the aqueous extract of syzygium cumini (pulp) was investigated for its possible hypoglycemic and antioxidant potentials in streptozotocin (stz) induced diabetic wistar female rats. a single intraperitoneal injection of stz at a dose of 55 mg/kg body weight elevated the glucose levels more than 230 mg/dl after 3 days. treatment with the aqueous extract of syzygium cumini (pulp) at 100 mg/kg and ...

The abilities of cysteine-containing compounds to support growth of Bordetella pertussis and influence pertussis toxin transcription, assembly, and secretion were examined. Cysteine is an essential amino acid for B. pertussis and must be present for protein synthesis and bacterial growth. However, cysteine can be metabolized to sulfate, and high concentrations of sulfate can selectively inhibit...

During inflammatory processes, immunocompetent cells are exposed to substantial amounts of free radicals and toxic compounds. Glutathione is a cysteine-containing tripeptide that an important ubiquitous antioxidant molecule produced in human organs. The intracellular content GSH regulates the detoxifying capacity cells, as well immune response. particularly liver, where it serves major non-prot...

six hundred 1-d-old male broilers (ross 308) were assigned to four experimental groups; each was composed of 5 floor pen replications of 30 birds including control (no enalapril), 15, 30 and 60 ppm enalapril in the drinking water. from d 21 to 49, all the chicks were exposed to low ambient temperature to induce ascites. mortalities were inspected to determine the cause of death and diagnose of ...

UNLABELLED Reactive oxygen species (ROS) overgeneration is involved in the pathogenesis of hepatitis C. The aim of this study was to evaluate the antioxidant status in the blood of HCV infected patients treated or not with standard therapy before and after supplementation of vitamins E, C and zinc. Biomarkers of oxidative stress were evaluated in the blood of three groups of patients: group 1 -...

Paracetamol (acetaminophen) poisoning is common throughout the world. The management of nonstaggered (acute) paracetamol overdose is based on the plasma paracetamol concentration plotted on a treatment nomogram. In the UK there are two treatment lines on this nomogram, with the lower treatment line used for individuals felt to be at 'high risk' of paracetamol-related hepatotoxicity either as a ...

The invasive blue crab Portunus segnis, which was collected from two sites on the Gulf of Gabès, is subject this work. This study based demonstrating accumulation capacity P. segnis by measuring concentrations cadmium, zinc, lead, and copper in gills hepatopancreas. enzymatic activities catalase, glutathione-S-transferase, reduced glutathione, lipid peroxidase were assessed region for first tim...

1. Tyrosine aminotransferase from guinea-pig liver is inactivated at neutral pH by a factor localized in the microsomal fraction. The inactivation, independent of exogenous L-cysteine, is rapidly reversed by addition of dithiothreitol. 2. The effects of physiological reducing agents on the enzyme inactivation were investigated. L-Cysteine and L-cysteamine enhance the inactivation rate of the en...

The present study was undertaken to evaluate glutathione and its related enzymes in beta-thalassaemia major and to elucidate the effect of splenectomy on glutathione metabolism. The study includes three groups, those are: healthy individuals (n= 35) taken as control, a group of beta-thalassaemia major children with intact spleen (n= 29) and a group of splenectomized beta-thalassaemia major chil...

This study was carried out to see whether corn extracts could reduce the accumulation of arsenic in different tissues of rat. Exposure to arsenic (700 microg/rat/day) orally for 15 days led to significant accumulation of arsenic and significant reduction in the concentration of reduced glutathione (GSH) in different tissues. While water, salt, ethanol and alkali extracts of corn were co-adminis...
