Abstract
Influence of trace elements in body metabolism and their physiological importance in various diseases have motivated their accurate and quantitative determination in biological tissues and fluids. Inductively Coupled Plasma emission (ICP) technique has been employed to determine the levels of seven trace elements (selenium, zinc, copper, cadmium, chromium, nickel and iron) in serum and tissue from 79 humans including normal, bilharzial and bladder cancer patients. Selenium, zinc and iron are significantly lower in the serum of bilharzial and malignant group than in control group. Cadmium is significantly higher in serum of malignant group than in control group. Other elements showing non-significant changes in serum. In malignant tissues all the studied elements except iron are significantly lower than the non-malignant tissue.
