Role of micronize purified flavonoid fraction and ethanol Graptophyllum pictum extract on experimental anal ulcer healing. Study on Wistar rat

Abstract

Aim of the studyTo evaluate the role of micronized purified flavanoid fraction and ethanol Graptophyllum pictum extract in the treatment of anal ulcer. MethodTwenty-eight Wistar rats were randomly allocated into four groups. Groups 2, 3 and 4 the anus were induced with croton oil, but was not induced on group 1. Groups 1 and 2 were treated with normal saline, while groups 3 and 4 were treated with micronized purified flavanoid fraction, and ethanol G. pictum extract, respectively. On 9th days blood sample were taken from the retro-orbital region, and Wistar was killed by cervical dislocation under ether anesthesia. The anal canal was resected up 2cm from anal opening, weighted, photographically taken to measure the percentage of residual ulcer, and then prepared for microscopic examination. Elisa methods were done for superoxide dismutase and malondialdedhyde. The total leukocyte in the anal specimen was counted under 400 magnification power. superoxide dismutase, anal coefficient, and total leukocyte for statistical analysis were using ANOVA and LSD, while malondialdedhyde and percentage of ulcers were using Kruskal–Wallis and Mann–Whitney. ResultTreatment with ethanol G. pictum extract dose of 100mg/kg BW significantly reduces the percentage of anal ulcer, the edema, leukocyte infiltration, and malondialdedhyde, and increase the superoxide dismutase in comparison without treatment. Treatment with micronized purified flavanoid fraction did not reduce the leukocyte, anal coefficient, and percentage of anal ulcer, only increase malondialdedhyde and decrease superoxide dismutase significantly.
