Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used in clinical medicine. Their utility is, however, often limited by the adverse effects they produce in the gastrointestinal tract. Oxidative stress has been shown to occur in the small intestine in response to the oral administration of indomethacin, an NSAID commonly used in toxicity studies. In view of this, the effect of curcumin, an agent with anti-oxidant properties, was evaluated on indomethacin-induced small intestinal damage in a rat model. Rats were pretreated with various doses of curcumin (20 mg kg(-1), 40 mg kg(-1) and 80 mg kg(-1)) before administering indomethacin at 20 mg kg(-1). Various parameters of oxidative stress and the extent of small intestinal damage produced by indomethacin, with and without pretreatment with curcumin, were measured. Macroscopic ulceration was found to occur in the small intestine in response to indomethacin. The viability of enterocytes from indomethacin-treated animals was significantly lower than those from control animals. Drug-induced oxidative stress was also evident as seen by increases in the levels of malondialdehyde and protein carbonyl and in activities of pro-oxidant enzymes such as myeloperoxidase and xanthine oxidase in indomethacin-treated rats. Concomitant decreases were seen in the activities of the antioxidant enzymes catalase and glutathione peroxidase in these animals. Pretreatment with curcumin was found to ameliorate these drug-induced changes. Thus, curcumin appears to hold promise as an agent that can potentially reduce NSAID-induced small intestinal damage.

Background: Routine evaluation of Iodine Deficiency Disorders (IDDs) is done through a national program called National Iodine Deficiency Disorder Control Program (NIDDCP). The aim of this study is to determine the goiter prevalence, to estimate salt Iodine and urinary Iodine levels. Materials and Methods: An institution-based cross-sectional study was conducted among 2700 school children across seven taluks of Chikmagalur. A total of 2700 children aged 6 to 12 years were selected from 30 clusters by multistage sampling method. The iodometric titration method and Sandell–Kolthoff method were used for the estimation of salt and urinary Iodine, respectively. Descriptive and Inferential statistics were used. Results: The prevalence of goiter was 13.0%. About 153 (28.3%) salt samples had inadequate iodine content (<15 ppm). Median Urinary Iodine Excretion was 126 μg/L. Conclusion: Chikmagalur district is still at risk of a significant public health problem which needs timely interventions and appropriate measures to prevent further consequences due to IDDs.
