Oxidative stress (OS) is a biological entity quoted as responsible for several pathologies including diabetes. Diabetes mellitus (DM) has been also associated to human cirrhosis. The present work was designed to study the occurrence of OS as well as morphologic alterations in rat livers following induction of DM. Two groups of rats were used: Control and(More)
In this investigation we have shown that severe liver disease with cerebral involvement can be followed by the presence of BB creatine kinase isoenzyme in serum. Groups of rats were injected with a bile acid mixture, oleic acid, albumin and normal saline respectively. Bile acids or/and oleic acid induced BB isoenzyme to leak from central nervous tissue and(More)
BACKGROUND/AIMS Hepatic cirrhosis accompanied by portal hypertension is a common cause of death in human beings. The aim of the present study was to develop an experimental model of hepatic portal hypertension associated with liver damage. METHODOLOGY To develop liver damage in rats, we used the toxic alkaloid monocrotaline. Two groups of male Wistar rats(More)
ICP (intrahepatic cholestasis of pregnancy) is characterized by pruritus and biochemical cholestasis, including raised SBAs (serum bile acids) and, usually, elevated aminotransferases levels. However, AHP (asymptomatic hypercholanaemia of pregnancy) is defined as the presence of total SBA levels above the cut-off value (11 microM) in healthy pregnant women,(More)
The genomic coding region of the hepatitis B surface antigen (HBsAg) was partially sequenced from 12 HBsAg-positive sera of carriers residing in Buenos Aires, Argentina. A phylogenetic analysis groups the 12 isolates into genotypes A (n = 4), B (n = 1), D (n = 2), and F (n = 5). The occurrence of genotypes A and D is not unexpected, considering the mainly(More)
The activity of bilirubin UDP-Glucuronyltransferase was determined in microsomes from normal and bile duct ligated rats. It was measured after 2 and 8 days following bile duct ligation and compared with normal rats. A decrease of 33% in the total enzyme activity was observed on day 2; a fall of 70% was founded on day 8. Bilirubin diglucuronide represented(More)
This review addresses recent and not so recent works that emphasize on the mechanisms by which liver damage can induce encephalopathy. Hepatic encephalopathy constitutes an intriguing complication in severe liver acute and chronic disease, whose pathophysiology is still not completely understood. In this pathology, alterations in normal brain function are(More)
The hypothesis of the present study was that diabetes mellitus might affect brain metabolism. Streptozotocin (STZ)-induced diabetic rats, treated with vanadyl sulphate (V) and sodium tungstate (T) were employed to observe the aspartate aminotransferase (AST), alanine aminotransferase (ALT) and creatine kinase (CK) activities in brain homogenates.(More)
