Thyroid hormone modulates cell membrane Na+/K(+)-ATPase. A detailed study of erythrocyte membrane Na+/K(+)-ATPase activity was carried out during experimental thyroglobulin immunization. During the process of immunization there was a sharp decline in Na+/K(+)-ATPase activity until the 98th day of immunization, when the thyroglobulin antibody titer was at(More)
Human urine is a potential source of various nutrients, minerals and trace elements. Its use as a fertilizer is growing popular among farmers. Here, we examined the pattern of changes in the counts of coliform, heterotrophic bacteria as well as physico-chemical characteristics of human urine during different days of storage under closed conditions at(More)
The present study aimed to evaluate the effect of UV-B irradiation on the functional integrity, and the metabolic and detoxifying capacity of isolated rat hepatocytes. Isolated rat hepatocytes were irradiated in various doses (400 Jm-2, 600 Jm-2, 800 Jm-2 and 1000 Jm-2). The cells were assayed for total lactate dehydrogenase, Na(+)-K(+)-ATPase, ornithine(More)
