Anti Ulceration Efficacy of Boiled Aqueous Leaf Extract of Morinda lucida on Ethanol Induced Gastric Ulceration Rats

Abstract

Stomach ulceration study was carried on 25 groups (5 rats each of the groups), groups (E, E₁, E_2, , E₃ and E_C, placed on 24 hours fasting before the single dose of intra peritoneal dose administration of 5ml/kg body weight of 99% ethanol and after one hour, received daily extract of dilution doses of ((500, 1000, 1500) mg /kg) body weight and 100 mg /kg body weight cimentidine (standard drug) respectively for 7 days. Groups (EA₁, EA_2, , EA₃ and EA_C, ) were treated with the same extract doses and drug concentration for 7 days before the dose ethanol administration. Group Eand 0 served as a positive control and a negative control respectively. On day 9, target organs; stomach and intestines were harvested under anaesthetize weighed, gross macroscopically and histomorphological studied. Result of the study showed plant inhibition on ethanol induced gastric ulceration; the standard drug (cemetidine) and the mapped extract doses of ((500, 1000, 1500) mg /kg) body weight respectively showed normal organ architecture. Ulcer index study activities 70% indicating evidence of curative and preventive index range 35 to 43% showed some inhibition as seen on the gastric mucosa of the treated group. It was observed that the treatment and anti- ulceration effect of boiled aqueous leaf extract metabolites showed reduction on the histomorphological changes in the gastric mucosa and provided inhibition effectiveness of ethanol induced injury.
