The effect of ligustrazine on peritoneal transport in peritoneal dialysis

Abstract

In order to investigate the effect of ligustrazine (Lig) i.p. on peritoneal permeability in peritoneal dialysis and its side effects, creatinine was given intravenously and continuously to maintain the high plasma creatinine level. All the rabbits were divided into three groups: normal control group (group A), group B treated with 0.12 % Lig and group C treated with 0.24 % Lig. The peritoneal dialysis of all rabbits lasted 2 h. The plasma and dialysate levels of glucose, protein and creatinine were observed immediate, 30 min, 60 min, 90 min, 120 min after dialysis. Creastinine dialysate/plasma ratio (D/P), protein D/P ratio, glucose D/Do at different time points after dialysis and creatinine mass transfer area coefficient (MTAC) at 120 min were calculated. The structures of peritoneum were observed under optical microscope and electron microscope after continuously intraperitoneal injection of Lig for 14 days. The results showed that the 90-min and 120-min creatinine D/P ratios in the group C were higher than in the group A. The 120-min creatinine MATC in the group C was higher than in the group A. The rabbits treated with Lig did not show significant structure changes of peritoneum and signs of peritoneal irritation. It was suggested that Lig could increase mass transfer ability of peritoneum without significant side effects.
