Background: Paraquat is nonselective bipyridyl herbicide that induces hepatotoxicity through oxidative stress. Vitamin C and chitosan have antioxidant as well as radical scavenger properties and show protective effects against reactive oxygen species (ROS). In the present study, hepatoprotective effects of chitosan and vitamin C were evaluated in common carp exposed to paraquat. Methods: Whi...
The energy metabolism of the English E-CMO strain of contagious equine metritis bacterium was studied in whole cells and cell extracts. This bacterium appears to have an active Krebs cycle and probably obtains energy by oxidative phosphorylation since glycolysis and the hexose monophosphate pathways appear to be absent. These conclusions are based on the findings that [U-14C]glucose incorporati...
The activities of glucose 6-phosphate and 6-phosphogluconate dehydrogenases, transketolase, phosphoglucose isomerase, and fructose 6-phosphate kinase were studied in extracts of wintering poplar (Populus gelrica) xylem. The xylem of wintering poplar showed high levels of transketolase, glucose 6-phosphate, and 6-phosphogluconate dehydrogenases. On recommencement of growth, the two dehydrogenase...
Light inactivation of glucose 6-phosphate dehydrogenase is rapid and occurs before photosynthetic O(2) evolution is measureable in intact chloroplasts. Likewise, dark activation is rapid. The major light induced change in the kinetic parameters of glucose 6-phosphate dehydrogenase is in maximal velocity.

The regulation of CO(2) assimilation by intact spinach (Spinacia oleracea) chloroplasts by exogenous NADP-linked nonreversible d-glyceraldehyde-3-phosphate dehydrogenase (EC 1.2.1.9) was investigated. This dehydrogenase mediated a glyceraldehyde 3-phosphate/glycerate 3-phosphate shuttle for the indirect transfer of NADPH from chloroplast to the external medium. The rate of NADPH formation in th...
BACKGROUND AND AIM The pathogenesis of neonatal hyperbilirubinemia hasn't been completely defined in Gloucose-6-Phosphate Dehydrogenase (G6PD) deficient newborns. The aim of this study was to detect the relationship between Gilbert's syndrome and hyperbilirubinemia in Gloucose-6-Phosphate Dehydrogenase (G6PD) deficient neonates. MATERIALS AND METHODS This case-control study was conducted in A...
1. The deoxyfluoro-d-glucopyranose 6-phosphates are substrates for both yeast and rat liver glucose 6-phosphate dehydrogenase. 2. The V(max.) values (relative to d-glucose 6-phosphate) were determined for a series of d-glucose 6-phosphate derivatives substituted at C-2. The V(max.) values decreased with increasing electronegativity of the C-2 substituent. This is consistent with a mechanism inv...
The generalization that 'when a metabolic sequence involves consecutive nicotinamide-adenine dinucleotide-dependent reactions, the dehydrogenases have the same stereospecificity' was tested and confirmed for three metabolic sequences. (1) NAD+-xylitol (D-xylulose) dehydrogenase and NADP+-xylitol (L-xylulose) dehydrogenase are both B-specific. (2) D-Mannitol 1-phosphate dehydrogenase and D-sorbi...
