Diabetes mellitus is a metabolic disorder characterized by chronic hyperglycemia. The management of the blood glucose level is a critical strategy in the control of diabetes complications. Inhibitors of carbohydrate hydrolyzing enzymes have been useful as oral hypoglycemic drugs for the control of hyperglycemia especially in patients with type II disables mellitus. The goal of the present study...

Phenoloxidase (Po) activity was measusred spectrophotometrically in serum, plasma and haemocytes (HLS) of the freshwater crayfish (Pontastacus leptodactylus). The highest activity was found in HLS suggesting that the haemocytes are the major source of the Po or its proform prophenoloxidase (proPO) in crayfish. Furthermore, the enzyme activity in serum samples was reduced after freezing the samp...

pseudomonas aeruginosa is an opportunistic pathogen that causes a variety of infections in compromised patients. the ability of pseudomonas aeruginosa to produce chronic infection is based in part on its ability to biosynthesis of biofilm, and alginate is the major polysaccharide in the synthesized biofilm. so alginate degradation is very essential in the dispersion of pseudomonas aeruginosa bi...

Penicilliurn expamum grown in a medium with rice husk as a carbon source produced an extracellular protease. The protease enzyme was isolated from culture broth by fractionation with acetone and column chromatography on Sephadex G- 100 and DEAE A-50. The protease enzyme was purified about 17.47 fold, with a recovery of 14%. The purified protease was homogenous on SDS polyacrylarnide disc ge...

Incubation of rat hepatocytes with epinephrine inhibited alanine aminotransferase (ALT) (80%) and aspartate aminotransferase (AST) (53%) activities with no effect on lactate dehydrogenase (LDH) activity. Injection of epinephrine caused a progressive increase with time in hepatic LDH activity, being 52% at 24 h. Preinjection with propranolol eliminated the hormone effect and caused further ...
