Renal and immunological dysfunction in Nickel-Electroplating Workers

Electroplating processes result in the emission of aerosoles of soluble nickel compounds. In our work we investigated health hazards associated with such exposure in a nickel-electroplating workshop. We examined the results of 50 male workers exposed to soluble nickel compounds and the results were compared to those obtained from 14 matched controls. Serum urea, creatinine and retinol binding protein were statistically significantly higher in exposed workers compared to the controls. Low levels of IgA and high levels of IgE were reported among our exposed workers. Reduction of spirometric measurements but not to the level of significance, was also demonstrated. The concentration of nickel in urine of workers averaged [2.9 Ug/L] and in serum averaged [3.4 Ug/L]. Statistically significantly positive correlation was found between serum levels of urea, creatinine, retinol binding protein and IgE and serum and urinary nickel of exposed workers

Nutritional and Biochemical significant studies on Friesian diary cows productivity

Proper nutrition for diary herds assesing the high yield. Adequate crurde protein content of the dairy ration is important to maintain the high productivity. This importance is maximized if it maintain sufficient level of degradable and undegradable intake protein. Dietary calcium and phosphorus must be enough and in balanced manner to enable the high producing cows to meet their requirements for lactation and / or pregnancy. Metabolic profile results showed that reduced milk yield may be -due to failier in maintenance adequate level of certain blood constituents due to dietary insufficiency of their parent nutrients
