Alterations in serum concentrations of several trace elements including copper, zinc, manganese, and the macroelement magnesium have been reported to occur in type-2 diabetes mellitus. This study is done to evaluate copper, zinc and magnesium status in diabetic and nondiabetic human subjects. In this comparative analysis, the serum concentration of copper, zinc and magnesium was estimated in 60 patients with type 2 diabetes mellitus without complication and 40 healthy non-diabetic subjects. The data was analyzed by students't' test and Pearson's correlation coefficient test.Mean serum concentration of copper was significantly elevated in diabetic patients compared to control subjects. Serum zinc levels were significantly low (p < 0.001) in diabetic subjects compared to controls . There were no significant differences in serum magnesium between groups. Fasting plasma glucose level has significant positive correlation with serum level of copper (r = 0.567; p < 0.001), while zinc has negative correlation (r = -0.311; p < 0.047), but there is no significant correlation of plasma glucose level with serum magnesium level. Diabetic patients have significantly lower mean serum zinc levels and significantly higher serum copper concentration compared with healthy controls respectively. Along with antidiabetic therapy, supplementation of zinc and magnesium and chelation of copper can reduce complications due to diabetes mellitus.

This study showed the usefulness of mycobacterial serine protease antigen and its antibody in detecting neurotuberculosis.

Anti-TPO antibody level was evaluated in 86 patients, along with 25 healthy controls to detect its change in various forms of thyroid nodules particularly in thyroid malignancy when compared with healthy controls. The study revealed that Anti-TPO antibody level was increased in Benign & toxic form of Multi nodular goiter and papillary carcinoma but there is no elevation of Anti-TPO antibody level in follicular adenoma or follicular carcinoma.
