the effects of therapeutic doses of dillsun, garsin, antum and statins on rat liver cytosolic phosphatidate phosphohydrolase (pap) activity, a key enzyme in triacylglycerol synthesis, and on serum and liver lipids were examined. lovastatin and simvastatin both stimulated the enzyme activity by 29% and 43%, respectively. the stimulatory effects were dose-dependent and accompanied by the decline ...

liver functional tests due to inflammatory process which induced by cholecystitis might changed and some clinicians suggested that these changes might help us to stone prediction in common bile ducts and decrease hazards of performing ercp and other invasive procedures. present study was performed for assessment of role of liver functional test in diagnosis of common bile duct stone in patients...

Background: Tyrosinemia type 1 is an autosomal recessive metabolic disorder, which typically affects liver and kidneys. It is caused by a defect in fumarylacetoacetate hydrolase or fumarylacetoacetase (FAH) enzyme, the final enzyme in the tyrosine degradation pathway. The disease typically manifests as early onset type in early infancy with acute hepatic crisis with hepatomegaly and bleeding te...

background: in patients who are hepatitis b virus (hbv) dna-positive, but hbv surface antigen (hbsag) -negative, the infection is referred to as occult hepatitis b infection (obi). occult hbv infection is harmful when other liver diseases are present, and can aggravate liver damage in in patients with chronic liver diseases. in human immunodeficiency virus (hiv) infection the suppression of vir...

It is in the field of hepatology that enzyme assays are performed most frequently for diagnostic purposes. Their interpretation requires knowledge of many factors that influence the serum level of the particular enzymes assayed. Therefore, these factors are discussed briefly in relation to liver disease before considering important developments such as the value of estimating D-glutamyltransfer...

ammonia is a toxic material for mammalians. it is detoxificated and converted to urea in the urea cycle in liver. each defect in the urea cycle cause increase in blood ammonia level. ornithine transcarbamylase enzyme (otc) is the second enzyme in the urea cycle that exists in mitochondria. otc deficiency is the most common hereditary disorder in the urea cycle. in this study, 45 hyper ammonia p...

The activities of phosphoenolpyruvate carboxykinase, ;malic enzyme', citrate-cleavage enzyme and glucose 6-phosphate dehydrogenase were assayed in homogenates of rumen mucosa, liver and adipose tissue of cattle. Rumen mucosa cytoplasm contained activities of ;malic enzyme' approximately sevenfold those of phosphoenolpyruvate carboxykinase, suggesting that the conversion of propionate into lacta...
