[Effect of peritonitis pathomorphology on rabbit model in peritoneal dialysis].
The study about peritonitis rabbit model is rarely, although peritonitis have been considered mainly complication in peritoneal dialysis. Twelve New Zealand rabbit were divided into peritonitis group and control group. The peritonitis group rabbit were injected with the dialysate containing alive staphylococcus aureus and the control ones with 0.9% saline into the peritoneum. The pathomorphology changes of the peritonitis were observed. The results showed (1) There was proliferation and swollen of mesothelial cells, vessel dilation and infiltration of inflammation cells in the peritoneum in the peritonitis group; and no such changes in the control group. (2) The D/D0 glucose concentration in the dialysate of peritonitis group was lower than that of the control ones at any point except the 0 min (P < 0.01). (3) The ratio of Cr concentration in the dialysate to Cr concentration in the plasma in the peritnitis group was significantly higher than that of the control group (P < 0.05). (4) The WBC count in the dialysate of peritonitis group was obviously higher than that of the control group all points except 0. These results implied that after injection of alive staphylococcus aureus to the peritoneal cavity of New Zealand rabbit for 48 hours, the pathomorphology change was similar with the characteristics of peritonitis complicated with peritoneal dialysis in patient.
