Applications of Morphometry in Non-tumour Pathology

Abstract The present study was designed to evaluate the protective effects of echinochrome (Ech) on intrahepatic cholestasis in rats induced by a single (i.p.) injection of alpha-naphthylisothiocyanate (ANIT) (75 mg/kg body weight). The rats were pre-treated orally for 48hr (one dose / 24hr) with Ech (1, 5 and 10 mg/kg body weight) or ursodeoxycholic acid (UDCA) 80 mg/kg body weight drug then, injected with ANIT. ANIT markedly increased serum activities of alanine amino transaminase (ALT), aspartate amino transaminase (AST) and alkaline phosphatase (ALP), which was accompanied by a massive inflammation of epithelial cells on bile duct at 24h after ANIT injection. ANIT also increased the levels of total protein (TP), total bilirubin (TB), direct bilirubin (DB), indirect bilirubin (IB), however decrease albumin content (ALB). In addition ANIT increased hepatic MDA and NO level and decreased GSH level and GST activity. The Ech exerted hepatoprotective and anticholestatic effects as assessed by a significant decrease in the activities of serum AST, ALT and ALP, and the levels of TP, TB, DB and IB as well as liver MDA level and NO level. In conclusion, Ech was found to possess hepatoprotective effect against intrahepatic cholestasis induced by hepatotoxin such as ANIT.
