Within 5 hours after administration of cortico-steroids to experimental animals, the activity of hepatic tyrosine-a-ketoglutarate transaminase is increased five-to tenfold (1-8). This enzyme cata-lyzes the initial step in tyrosine degradation and is one of several mammalian enzymes the activity of which is rapidly and substantially elevated by corticosteroids (9). Adrenal steroids also depress ...

The current study prepareded to evaluate histopathological and some physiological parameters changes after treated with Nerium oleander L lead. Thus concentrated on tissue structures in the liver aqueous extract of lead solution. Its caused intense flaws albino mice. After expiration experimental time, blood specimens collecting value Aspartate Transaminase (AST), Alanine (ALT), urea (BUN) crea...

Methods: The effect of Abana pretreatment (75 mg /100 g ) for a period of 60 days on isoproterenol (20 mg/100 g s.c. twice at an interval of 24 hrs) induced lipid peroxidation was studied in rats. Marker enzymes levels such as creatine kinase, lactate dehydrogenase, alanine transaminase and aspartate transaminase were assessed in serum and heart homogenate. Glutathione content and lipid peroxid...
