Role of Aqueous Bark Extract of Terminalia Arjuna on Serum Enzymes in Cigarette Smoke Exposed Rats

Abstract : Cigarette smoking is the leading cause of mortality and a major public concern. The aim of our study to investigate the role of aqueous bark extract of Terminalia arjuna on serum enzymes in cigarette smoke exposed rats. A total fifteen (15) adult healthy Wistar rats from 100-158 were divided into three groups (A, B and C) each containing five rats. Group (A) serving as control without exposure to cigarette smoke, Group (B) and (C) served as the experimental groups. The group (B) was exposed to Cigarette smoke (6 Cigarettes) for one hour/day for 30 days and experimental group (C) was exposed to cigarette smoke along with oral administration of aqueous bark extract of Terminalia arjuna (5mg/rat /day) for 30 days. The results indicate that, a significant increase in Alanine amino transferase (ALT) and Aspartate amino transferase (AST) after exposure to cigarette smoke in comparison to control group while, a significant decrease in ALT and AST level after cigarette smoke exposure along with oral administration of aqueous bank extract of Terminalia arjuna in comparison to Cigarette smoke exposed rats due to antioxidant defence mechanism
