- Abstract
Objective: To study the change of AQP3 expression in colonic tissues of different degrees' diarrhea model rats. Methods: SD rats were randomly divided into four groups: control group, mild diarrhea group, moderate diarrhea group and severe diarrhea group. the rat models of diarrhea were established by using different concentrations of sennan intragastric administration for 7d; The water content of feces was measured. Using optical microscopy to observe the pathological and morphological changes in colonic tissues of different degrees' diarrhea model rats; The expression of AQP3 protein in colonic tissues were detected by immunohistochemistry assay and Western blot. The expression of AQP3 mRNA were detected by RT-PCR. Results The water contents of feces were significantly higher in diarrhea model groups (P<0.01), pairwise comparison, the difference were statistically significant (P<0.05); HE staining showed, compared with the control group, there were more sticky secretions in diarrhea groups, glandular cells of mucous membrane laye markedly swollen, we could see a large number of congested capillaries in submucosa, the heavier the degree of diarrhea, the more obvious change; Immunohistochemistry assay and Western blot, RT-PCR results showed that compared with the control group, AQP3 protein and AQP3 mRNA expression in colon were reduced in diarrhea groups(P<0.01), and the heavier the degree of diarrhea, the lower expression quantity (P<0.05).Conclusion AQP3 expression in diarrhea rats colon were decreased, and the heavier the degree of diarrhea, the lower expression quantity.
