Background: Gastric ulcer is a common gastrointestinal disorder with global consequence, which is aggravated by an imbalance between the aggressive factors and factors that maintain the mucosal integrity. The role of Piliostigma thonningii leaf extract on hematological indices of indomethacin-induced gastric mucosa lesions in Wistar rats was examined.
Methods: Thirty-six male rats were divided into six groups of 6 rats each. Group I, the normal control, II gastric ulcerated + cimetidine (standard control), III extract only (100mg/kg bwt), while IV, gastric ulcerated control, V gastric ulcerated + extract (100mg/kg bwt) and VI gastric ulcerated + extract (200mg/kg bwt). After 12 days of administration, gastric ulcer was then induced by oral administration of 40mg/kg bwt indomethacin to rats in groups II, IV, V and VI. The rats were sacrificed 12 hours after indomethacin treatment and blood collected for hematological assay.
Results: The RBC count and Hb pattern were similar. There was a significant (P<0.05) decrease in RBC and Hb of the ulcer control group which was normalized on administration of 200mg/kg bwt of P. thonningii extract. The MCV of the ulcer lesion was significantly (P<0.05) reversed to normal by the extract.
Conclusions: The P. thonningii leaf extract showed promising result by normalizing decreased levels in RBC and Hb caused by ulcer. Except for platelet counts, the WBC count and differential WBC counts were quite positive. It was able to reverse macrocytosis caused by ulcer lesions to normal, hence exhibiting a hemato-protective nature.
