The Role of Allium saralicum Extract on Prevention of Acetaminophen-Induced Hepatic Failure: an Experimental Study

Abstract

Background and objectives: Acetaminophen (APAP) is a common analgesic medicine whose overdose leads to severe hepatic dysfunction. Due to the known antioxidant properties of Alliumspecies, the present study aimed to evaluate the protective effects of Allium saralicum plant on APAP induced liver toxicity. Methods: The hydro-alcoholic extract of A. saralicum was prepared by maceration and ultrasonic methods. Forty-two rats in seven groups were treated by gavage as follows: groups 1 and 2 received normal saline, groups 3 received 400 mg/kg of A. saralicum hydro-alcoholic extract, and the groups 4-7 were treated with 50, 100, 200 and 400 mg/kg of A. saralicum extract, respectively. After two consecutive weeks, the therapeutic groups, as well as the positive control (APAP) group, were administered a single dose of APAP (2 g/kg). After 48 hours, the animals were anesthetized, and blood and liver samples were collected for histological and biochemical examinations.Results: Our findings indicated that APAP caused a significant rise in ALT (pA. saralicum extract, a remarkable improvement was observed in the functional and oxidative stress indices of liver tissue alongside histopathologic alterations. Conclusion: Our results showed that A. saralicum extractsignificantly improved APAP-induced hepatic failure through inhibition of oxidative/nitrosative stress.
