Abstract:
AIM: To investigate the effect of peritoneal vibration on the peritoneal permeability and the peritoneal surface layer. METHODS: Peritoneal transport rate was examined in twelve male SD rats. Six (S group) were put on an electronic shaker and the other six were used as control (C group). After that, the peritoneum was examined by electron microscopy (EM). RESULTS: The net ultrafiltration volume (NUF) in the S group was lower than that in the C group. This difference in NUF was due to both a significantly higher peritoneal fluid absorption rate and a significantly lower transcapillary ultrafiltration rate in S group as compared to C group. The peritoneal direct lymphatic absorption rate was higher in S group. The transport rates of small solutes were also significantly higher in S group. EM showed that the thickness of the peritoneal surface layer was significantly decreased in S group. CONCLUSION: Our results suggest that the peritoneal surface layer may be an important layer in modulating the peritoneal transport rate.
