Transperitoneal transport of uric acid: impact of p-cresol, sodium hyaluronan, and sodium deoxycholate in vitro.

Our study investigated uric acid transport across isolated parietal peritoneum taken from the anterior abdominal wall of white New Zealand rabbits and placed inside a modified Ussing-type chamber. Values for transfer from the mesothelial to the interstitial side of membrane (M --> I) were calculated using the mathematical model of mass transport and are expressed as a coefficient of diffusive permeability [P (in centimeters per second)]. Four separate series of experiments were done.
