Effects of some antibiotics on glucose 6-phosphate dehydrogenase in sheep liver

چکیده
In vitro effects of penicillin, sulbactam, cefazolin, and amikacine on the activity of the enzyme glucose6-phosphate dehydrogenase in sheep liver were investigated. Glucose 6-phosphate dehydrogenase was purified from sheep liver, using a simple and rapid method. e purification consisted of two steps, preparation of homogenate and 2’, 5’-ADP Sepharose 4B affinity chromatography. As a result of the two consecutive procedures, the enzyme, having the specific activity of 11.76 EU/mg proteins, was purified with a yield of 35.72% and 1.913 fold. In order to control the enzyme purification SDS polyacrylamide gel electrophoresis (SDS-PAGE) was done. SDS-PAGE showed a single band for the enzyme. In addition, I50 values of the antibiotics were determined by plotting activity % vs. antibiotic concentrations. I50 values were 17.71 mM for penicillin, 27.38 mM for sulbactam, 28.88 mM for cefazolin, and 30.59 mM for amikacine.

Vitamin C and Chitosan Alleviate Toxic Effects of Paraquat on Some Biochemical Parameters in Hepatocytes of Common Carp
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...

Glucose-6-phosphate dehydrogenase (G6PD) deficient subjects are vulnerable to oxidative stress. Quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against H2O2-induced oxidative damage in G6PD-deficient and normal human erythrocytes. Erythrocytes of G6PD-deficient (n = 10) and normal (n = 10) subjects were ...
