Özet
BACKGROUND/AIMS: The effect of kefir on peptic ulcer disease was evaluated in an experimental model, with non-steroid anti-inflammatory drugs, together with the determination of gastric mucus secretion by quantitative digital histochemistry. MATERIALS AND METHODS: The experimental group included 28 male albino Wistar rats. After a diet with standard rat bait for 7 days, 14 rats were fed with kefir for 7 days while the others were kept on the same diet. At the 14th day, indomethacin was injected to 7 of the rats fed on kefir and to 7 of the rats on standard rat bait. All the rats were sacrificed after 4 hours. Gastric erosion and ulceration were scored histopathologically. Mucosal mucus was quantified by image analysis, and periodic acid-Schiff stained area percentage was determined. RESULTS: Erosion and ulceration were identified only in cases that received indomethacin. In the cases on kefir, erosion was identified in 6 cases (86%) and ulceration in 1 case. Rats fed on standard diet had erosion in 4 cases (57%) and ulceration in 3 (43%), but the difference was statistically insignificant (Mann-Whitney test, p=0.25). The stained area percentage for gastric mucus was not different between the four groups (Kruskal-Wallis test, p=0.313). CONCLUSIONS: These findings suggest that kefir does not change gastric mucus secretion. Although statistically insignificant, as there were more cases with ulceration in cases on the rat diet, kefir might have a beneficial effect on peptic ulcer disease induced by non-steroid anti-inflammatory drug. This requires further evaluation in larger series.
