Lactobacillus plantarum IS-10506 Accelerates Healing of Gastric Injury Induced by Ketorolac in Wistar Rats

Abstract

Gastric injury is an event that often occurs due to many factors, such as the use of drugs, stress factors, infections, chemicals, etc. The use of histamin 2(H2) receptor antagonist drugs and pump inhibitors have become the choice for gastric injury treatment so far and requires a relatively long time. The widespread use of probiotics has been shown to affect the healing process of digestive tract disorders, for example in the small intestine. This study aimed to investigate the effect of Lactobacillus plantarumIS-10506 in acceleratingthe healing of gastric injury induced by ketorolac in the rat. The experimental study used 64 Wistar rats divided into 4 groups, group 1 (control), group 2(ketorolac administration), group 3 (ketorolac and probiotic administration), and group 4(preventive treatment with probiotic before, ketorolac administration, and treatment with probiotic). Each group was divided into 4 subgroups based on the day of sacrifice, days 1, 5, 7, 10. The healing of gastric injury evaluating by epithelial defects improvement and fibroblast cells by hematoxylin and eosin (HE) staining.The group induced by ketorolac (group 2) showed the highest epithelial defect score (p=0.048) on day 1. The repair of the epithelial defect in group 3 and group 4 were significantly increased on day 5, while group 2remains defectiveon day 5(p=0.019). Fibroblast cells of groups 3 and 4 decreased significantly more than others on day 10(p=0.024). Lactobacillus plantarum IS-10506 influences the healing acceleration of gastric injury by ketorolac by enhancing epithelial regenerationand fibroblast cells.
