To date, no attempt has been made to study alterations occurring in the amino acid profile in chronic models of thioacetamide-induced liver cirrhosis. In this work, changes in serum amino acids and proteins in rats with thioacetamide-induced liver cirrhosis are reported, together with changes in enzyme activities in the liver and serum. Seventeen female Wistar rats were used. Eight rats were gi...

BACKGROUND Persistently raised transaminase levels often prompt the clinician to investigate for liver pathology. Previously, some of our patients with Duchenne's muscular dystrophy have had investigations to look for liver disorders when the alanine transaminases (ALTs) were found incidentally to be high. AIM The objective of the study was to ascertain the levels of the transaminases in pati...

Background: Exposure to ionizing radiation is inevitable. Using of low-level laser therapy (LLLT) stimulates tissue repair and reduces inflammation. The objective of the present study aimed at evaluating the therapeutic efficacy of Helium-Neon (He-Ne) laser in stimulating the reparative processes in the liver of mice after whole body gamma-irradiation (WBγ-I). Materials and Methods: Two hundred...

Pediatric obesity has increased dramatically all over the world and nonalcoholic fatty liver disease (NAFLD) is one of the most frequent complications associated with excess adiposity. NAFLD causes serum transaminase elevation and liver disease, which could end up in fibrosis, cirrhosis and eventually hepatocellular carcinoma. NAFLD seems to be associated with the metabolic complications of obe...

We examined whether octacosanol, the main component of policosanol, attenuates disrupted hepatic reactive oxygen species metabolism associated with acute liver injury progression in rats intoxicated with carbon tetrachloride (CCl(4)). In rats intoxicated with CCl(4) (1 ml/kg, i.p.), the activities of serum transaminases increased 6 h after intoxication and further increased at 24 h. In the live...

BACKGROUND To develop a screening algorithm to detect hepatic steatosis in overweight and obese adolescents. METHODS We performed a cross sectional study of 129 overweight adolescents 13-18 yrs. The primary outcome, hepatic steatosis was defined as an intracellular triglyceride content > 5.5 mg/g and quantified using (1)H-magenetic resonance spectroscopy. Primary predictor variables included,...

Upregulation of heme oxygenase-1 (HO-1) has been proposed as an adaptive mechanism protecting against ischemia/reperfusion (I/R) injury. We investigated HO-1 expression in 38 human liver transplants and correlated this with I/R injury and graft function. Before transplantation, median HO-1 mRNA levels were 3.4-fold higher (range: 0.7-9.3) in donors than in normal controls. Based on the median v...
