[Antiinflammatory effects of the betamethasone sodium phosphate enema on carrageenan induced colitis in the rabbit].
The effect of the betamethasone sodium phosphate (BSP) enema on the colonic mucosal lesions in the carrageenan induced colitis (rabbit) was examined laboratory and histologically. The effect of drugs were evaluated by the changes of body weight, fecal occult blood, blood analysis, and histological examinations. Fecal occult blood were highly positive in the physiological saline treated but less positive in the BSP groups. In the blood analysis, anemia was not detected in both groups. Histological findings such as the defect of superficial epithelium, crypt abscess, inflammatory cell infiltration, atrophic changes, defect of muscularis mucosae, goblet cell depletion, goblet cell depletion, ulcer formation, and edematous change were scored to evaluate the colonic mucosal lesions. These scores (Mean +/- S.D.) were 4.4 +/- 1.96, 7.7 +/- 3.67 for BSP, physiological saline groups respectively. From these results, BSP enema showed an antiulcerative effect on the entire colonic lesions in the carrageenan induced colitis in the rabbit.
