Background:Helicobacter pylori related gastritis is a major health ailment in developing nations. There is high morbidity and mortality ranging from chronic gastritis to gastric malignancies. Prevalence of H. pylori infection varies markedly from country to country and in a country, region to region.Aim:To study the prevalence of H. pylori gastritis in patients undergoing endoscopy and its association with the development of gastrointestinal diseases.Subjects and Methods:The study was carried out in a Medical College Hospital in Kerala, India. Patients presenting with dyspeptic symptoms were subjected to upper gastrointestinal endoscopy and investigated for H. pylori infection through histopathological examination and rapid urease test of biopsy specimen. Diagnosis of H. pylori infection was made if one or both diagnostic test results were positive. Data analysis was carried out using the statistical package for social sciences, for Windows version 16.0 (SPSS 16; Chicago, IL, USA).Results:H. pylori infection was diagnosed in 62.0% (329/530) of patients screened. There was no statistically significant difference in sex and age related distribution (<50 year age group and >50 year age group) of H. pylori infection. However, a statistically significant association of H. pylori infection with the presence of endoscopic abnormalities, peptic ulcer, and dysplasia/cancer was seen.Conclusion:The prevalence of H. pylori infection is significantly high in rural and suburban population of Ernakulam district, Kerala. Early detection and prompt treatment are essential for prevention of serious complications.
The illegal enrichment of anabolic androgenic steroids in over-the-counter dietary supplements is well documented, but the health consequences have not been widely recognized. Three recent reports document cholestatic jaundice and nephropathy due to these compounds. We present 3 additional cases of anabolic androgenic steroid-enriched dietary supplement-induced hepatotoxicity and 1 case of renal failure, and we review the literature and the relevant features of this growing health concern. Recognition of this entity could obviate the need for invasive diagnostic testing and hospitalization and facilitate diagnosis and appropriate counseling.
BackgroundBreast cancer is a major problem in the United States leading to tens of thousands of deaths each year. Although citrus auraptene suppresses cancer in numerous rodent models, its role in breast cancer prevention previously has not been reported. Thus, our goal was to determine the anticarcinogenic effects of auraptene against breast cancer.MethodsThe effects of auraptene on cell proliferation of MCF-7 and MDA-MB-231 human breast carcinoma cells in culture was assessed by measuring metabolism of a substrate to a formazan dye. Dietary effects of auraptene on tumor incidence, multiplicity and latency were studied in the N-methyl nitrosourea (MNU) induced mammary carcinogenesis model in female Sprague Dawley rats. The concentration of auraptene in rat tissues was analyzed by reverse phase HPLC. Cyclin D1 expression in MCF-7 cells and rat tumors was measured by western blot.ResultsAuraptene (500 ppm) significantly delayed median time to tumor by 39 days compared to the MNU only group (p < 0.05, n = 24–26). Auraptene (10 μM) reduced Insulin like Growth Factor-1 (IGF-1, 10 ng/mL)-induced cyclin D1 expression by 40% in MCF-7 cells. In comparison, western blot analysis of rat mammary tumors (n = 10 per group) confirmed that auraptene (500 ppm) significantly reduced (p < 0.05) cyclin D1 expression by 49% compared to the MNU only group. Analysis of rat mammary tissue extract by HPLC with fluorescence detection indicated an average concentration (means ± S.E.) of 1.4 ± 0.5 μM and 1.8 ± 0.3 μM in the normal mammary glands of the auraptene 200 ppm and 500 ppm groups, respectively. The concentration (means ± S.E.) of auraptene in the mammary tumors of the auraptene 200 ppm group was 0.31 ± 0.98 μM.ConclusionOverall, these observations suggest that the predominant effect of auraptene was to delay the development of tumors possibly through the suppression of cyclin D1 expression. These results point to the potential chemopreventive effects of auraptene in mammary carcinogenesis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
