Studies on interfacial potentials and currents of urine-urea systems across urinary bladder membrane.

ABSTRACT

Interfacial potential of urine-urea mixture across urinary bladder membranes of goat has been studied by comparing membrane-solution resistance and current data. It has been found that interfacial potential of urine solution is higher as compared to urea solution and that of urine-urea system increases with increase in concentration of urea in urine. Current generated in the system decreases with decrease in concentration of urea in the urine. Implications of electro-physiological studies in understanding the micturition process are discussed.
