Official Title: Vitamin E Level in Buccal Cells of Arsenicosis Patients Following Vitamin E Supplementation
Brief Summary: To understand the pathogenesis of chronic arsenic toxicity, the investigators need to know the levels of vitamin E in patients chronically exposed to high concentration of arsenic and if changes are found, what happens when supplemented with vitamin E. The buccal cells and serum of patients will be collected for the estimation of vitamin E both before and after supplementation with vitamin E. Similar samples will be collected from similar number of arsenic exposed controls and healthy volunteers for comparison.
