متن کاملEvaluation of Prothrombin Time in Acute Acetaminophen Overdose treated by N-acetylcysteine
Background: Acetaminophen (N-Acetyl-p aminophenol; APAP) is one of the most common types of analgesics. It is also the most common xneobitic reported to poison centers.

متن کاملAlanine aminotransferase/aspartate aminotransferase ratio reversal and prolonged prothrombin time: a specific indicator of hepatic cirrhosis.
BACKGROUND Both ALT/AST ratio reversal (AST/ALT > 1) and prolonged prothrombin time are separately related to hepatic cirrhosis. Ratio reversal means that in normal individuals ALT is more than AST and thus ALT/AST > 1 but with development of cirrhosis AST becomes > ALT and so AST/ALT > 1 or ALT/AST < 1. This study was conducted with the idea that prolonged prothrombin time and reversed (AST/AL...
