| Outline of Final Research Achievements |
We clarified that plenty of CReg, CD46, CD55 and CD59 were expressed in mesothelial cell of human peritoneum. When we investigated whether performance of PD therapy influenced the complement system in PD patients, we got correlation between levels of sC5b-9 in PD fluid and D/P creatinine and reverse-correlation between D/P creatinine and expression of CD55 in peritoneal mesothelium in the PD patients. Between serum levels and PD fluids, C4 was well correlated but not C3. Our results suggested that PD therapy might change CD55 expression of mesothelium and influence D/P creatinine in the PD patient dependent on activation of the alternative pathway presumably.
Using an acute peritonitis model on rat, we showed the supportive data of the possibilities of anti-complement therapies because suppression of C5a could improve the acute peritoneal injuries.
