Effects of prolonged sun expoure on vitamin d and lipid panel in healthy sudanes subjects

Abstract

ABSTRACT lhe study was conducted in Sudan — Khartoum state, during the period lrom jun-2013 through April 'l()l4, to evaluate the ellects otexposurc to sun ray tor longer time on vitamin l) and Lipid panel. lit) healthy Sudanese subjects were enrolled in the stud)". clussilicd according to duration olisun e.\'posurc time into three groups. the lirst -tiroup exposed to 0-l ll/day was control group, and the second test group exposed to Z-4ll/day and the last test group exposed to 5-61-l/day. each group included 50 subject.
