Electrokinetic energy conversion studies of urine-oxalic acid systems across urinary bladder membrane.

Electrokinetic studies of urine-oxalic acid systems with increasing concentration of oxalic acid in urine have been carried out across urinary bladder membranes. It has been found that electro-osmotic flux and streaming current decrease with increase in concentration of oxalic acid in urine while hydrodynamic flux and streaming potential increase with increase in concentration. Kinetic energy term (alpha 1) and polarizability term (alpha 2) have been computed for these systems and it has been found that polarizability decreases much faster with increase in concentration of oxalic acid in urine. Electrokinetic energy conversion of these systems have been computed and it has been found that electrokinetic energy conversion is maximum for urine and it decreases with increase in concentration of oxalic acid in urine. Poor energy conversion may lead to sluggish flushing action which may ultimately lead to formation of urinary calculi in the bladder and so present study may be of some use in predicting electrophysiology of the bladder.
