Abstract

Objective: Evaluating the influence of sodium hyaluronate on the proliferation rate of attached and nonattached human peritoneal mesothelial cells to elucidate whether this is a possible mechanism of action in peritoneal tissue repair : Controlled laboratory experiment. Sett : A university hospital. Patient(s): Five patients undergoing colorectal surgery for noninfectious reasons. Intervention(s): Human peritoneal mesothelial cells were harvested from patients undergoing a laparotomy for noninfectious reasons. Cells, both nonattached and attached, were incubated for 4 and 24 hours with different concentrations of sodium hyaluronate. Thereafter, the cell proliferation rate was measured by XTT (2,3-bis-(2-methoxy-4-nitro-5-sulfophenyl)-2H-tetrazolium-5-carboxanilide) colorimetric assay. To mimic peritoneal injury, the cells were exposed to tumor necrosis factor α and/or lipopolysaccharide and were incubated immediately or after 24 hours of exposure to 0% or 0.2% sodium hyaluronate. Afterward, the cell proliferation rate was measured. Main Outcome Measure(s): Proliferation rate measured by XTT assay. Result(s): Sodium hyaluronate significantly increased the proliferation rate of mesothelial cells, both in a nonattached (P<.005) and attached (P<.001) state. Exposure of the mesothelial cells to tumor necrosis factor α and/or lipopolysaccharide diminished the cells' proliferation rate. However, incubation of these exposed cells with 0.2% sodium hyaluronate significantly increased the proliferation rate, regardless of whether the sodium hyaluronate was added immediately (P<.001) or after 24 hours (P<.001). Conclusion(s): Sodium hyaluronate increases the proliferation rate of human peritoneal mesothelial cells, both attached and nonattached, under normal conditions and after stimulation with tumor necrosis factor α and/or lipopolysaccharide.
