Ethanolic extract of Lannea coromandelica stem bark: Histopathology and infiltration of inflammatory cells in the rat's gastric

This study determined the efficacy of extract of the stem bark of Lannea coromandelica (ESBLc) on histopathology and inflammatory cell infiltration in the gastric of rats induced by mefenamic acid. We grouped 20 rats (Rattus norvegicus) into 5; Group 1 (positive control, mefenamic acid + sucralfate suspension), Group 2 (negative control, mefenamic acid), Group 3 (mefenamic acid + ESBLc 1575 mg/kg), Group 4 (mefenamic acid + ESBLc 3150 mg/kg), and Group 5 (mefenamic acid + ESBLc 3600 mg/kg). The dose of mefenamic acid used was 23.25 mg/kg, given orally for 7 days. Gastric histopathological observations were carried out qualitatively, and inflammatory cell infiltration was analyzed quantitatively by one-ay ANOVA. The qualitative and quantitative analysis results showed that ESBLc had efficacy in restoring damaged gastric tissue of rats; statistically, 3150 mg/kg and 6300 mg/kg effectively reduced inflammatory cell infiltration. ESBLc recovered the function of gastric organs of Rattus norvegicus L. induced by mefenamic acid, including improved mucosa and reduced inflammatory cell infiltration in the gastric. The doses of ESBLc, which effectively reduced inflammatory cell infiltrations, were 3150 mg/kg and 6300 mg/kg BW.
