ABSTRACT
OBJECTIVE: The aim of this study was to neutralize acidic pH using an alkaline dialysate for continuous ambulatory peritoneal dialysis (CAPD) in mice with peritoneal carcinomatosis (PC) and to investigate the change of the pH level in the acidic fluid along with its effects on liver oxidative stress, liver and kidney histopathology and the lifespan of the body. MATERIALS AND METHODS: A total of 38 mice were randomly divided into 4 groups.PC development was inhibited by intraperitoneal injection of Ehrlich tumor cells in all mice in each group. RESULTS: In the group-1 receiving CAPD, the pH levels of acidic liquid were higher; and the levels of liver TBARS were lower with higher reduced glutathione levels. Histopathological damage in group-1 was less than in group-2. In Group 3 receiving CAPD, the average lifespan extended by 10.4%. The average lifespan extended by 26.1%. CONCLUSION: This study indicated that applying CAPD with alkaline dialysate in PC contributed to the neutralization of acidosis of the intraperitoneal acid structure;had favorable effects on oxidative stress markers in liver tissue; prevented histopathological injury in liver and kidney tissues, and extended the life span of the body in mice. As this is a simple, inexpensive, and easily available method, larger studies are warranted to evaluate its effects.
