The purpose of this study was to ascertain change in structure of mucosa of small intestine, if any, in small intestine of Swiss albino mice as an effect of chronic use of nonsteroidal anti-inflammatory drugs–Ibuprofen. Longitudinal study conducted on 46 adult Swiss albino mice, 23 as experimental and 23 as control. Ibuprofen was given at a dose of 40 µg/g body weight per day for 6 weeks by intragastric route in experimental group of mice while control group of mice received same volume of distilled water. Mice of both the groups were sacrificed and desired segments of small intestines were dissected out and tissues were subjected to histological processing. Histomorphometry was performed and relevant photomicrographs were obtained. Student's unpaired t test by GraphPad Prism 6 software. Height of villi was not significantly altered but there was significant reduction of the number of goblet and non-goblet cells (enterocytes and other columnar cells) in mucosal lining of the small intestine of experimental group of mice. Percent distribution of the goblet and non-goblet cells was not altered in villi of two groups. Chronic exposure of Ibuprofen in therapeutic dosage caused reduction of the functional cell mass in lining epithelium of villi of middle segment of small intestine. However, there was no evidence of ulcerative or hemorrhagic lesion.

Objective To investigate the effect of intermittent fasting on metabolize and gut microbiota in obese presenium rats fed with high-fat-sugar-diet. Methods We fed the Wistar rats with high-fat and high-sugar diet to induce adiposity, and the rats for intermittent fasting were selected base on their body weight. The rats were subjected to fasting for 72 h every 2 weeks for 18 weeks. OGTT test was performed and fasting blood samples and fecal samples were collected for measurement of TC, TG, HDL-C and LDL-C and sequence analysis of fecal 16S rRNA V4 tags using Illumina. Gut microbial community structure was analyzed with QIIME and LEfSe. Results After the intervention, the body weight of the fasting rats was significantly lower than that in high-fat diet group (P<0.01). OGTT results suggested impairment of sugar tolerance in the fasting group, which showed a significantly larger AUC than compared with the high-fat diet group (P<0.05). Intermittent fasting significantly reduced blood HDL-C and LDL-C levels (P<0.05) and partially restored liver steatosis, and improved the gut microbiota by increasing the abundance of YS2, RF32 and Helicobacteraceae and reducing Lactobacillus, Roseburia, Erysipelotrichaceae and Ralstonia. Bradyrhizobiaceae was found to be positively correlated with CHOL and HDL-C, and RF39 was inversely correlated with the weight of the rats. Conclusion Intermittent fasting can decrease the body weight and blood lipid levels and restore normal gut microbiota but can cause impairment of glucose metabolism in obese presenium rats.
