title: [Changes of transport functions in peritoneum caused by glucose and its penetration in vitro].
abstract: The changes of the transperitoneal molecules transport caused by glucose and dynamics of its transport have been determined in the case of undamaged tissue and the membrane with injured mesothelium in the in vitro studies. In the intact glucose induced increase of peritoneal uric acid absorption (40%) and lowering of urea and gentamicin excretion (25-40%). Glucose in the dialysis fluid lowered uric acid absorption and urea excretion (20-40%) in denuded animal peritoneum. The transperitoneal glucose transport remained constant at 2.61 x 10(-4) x cm x s-1. The mesothelium destruction caused an increase (32%) of mean values of absorption and excretion of this compound. The obtained results suggest that modifications of transport functions of the peritoneum caused by glucose depend rather on direct action of hypertonicity and metabolic effects of glucose than of the osmotic gradient. Furthermore, these changes may contribute to the rapid transperitoneal transport of glucose which increase after the destruction of the mesothelium.
