ABSTRACT
Objective: To explore the change of bone mass density(BMD) and micronutrients in middle-aged and old patients with iron overload and the effect on levels of micronutrients.Methods: BMD was measured by dual energy X-ray absorptiometry(DXA) in 19 middle-aged and old patients with iron overload and 41 age-and gender-matched healthy subjects.Serum selenium(Se)was measured by fluorospectrophotometry.Serum zinc(Zn) was measured by inductively coupled plasma atomic emission spectrometry(ICP-AES).Plasma vitamin A,D and E were measured by HPLC.The levels of blood lipid and plasma homocysteine were measured by automatic biochemical analyzer.Results: Plasma vitamin E of 19 iron overload patients was significantly lower than control group,and the levels of triglyceride and homocysteine increased significantly(P
