Laparoscopic incisions at the lower umbilical verge

Abstract

with conventional cuprophane membranes.4 Haemodialysis with high flux dialysers and polysulfone or polyacrylonitrile membranes lowers t32 microglobulin concentrations, and an improvement in shoulder pain in patients changed to high flux dialysers has been reported.5 The mechanism of the improvement is not clear; possibly amyloid is no longer deposited and the associated inflammation decreases. The improved biocompatibility of these membranes is known to be associated with reduced activation of some mediators of the inflammatory response.
