title: Influence of peroperative lavage solutions on peritoneal defence mechanisms in vitro.
abstract: OBJECTIVE
  To find out the in vitro reaction of mesothelial cells and polymorphonuclear leucocytes (PMN) to incubation with seven commonly-used lavage solutions.
  
  
  METHODS
  Experimental study.
  
  
  METHODS
  Laboratories, The Netherlands.
  
  
  METHODS
  Cultured human peritoneal mesothelial cells and isolated PMN.
  
  
  METHODS
  Incubation of cells with clinically used lavage solutions (sodium chloride, Hartmann's solution, povidone-iodine, Dakin's solution, taurolidine, chlorhexidine, and hydrogen peroxide).
  
  
  METHODS
  Activation of monolayers of mesothelial cells and PMN measured by release of oxygen free radicals (chemiluminescence) and interleukin (IL)-8 concentrations and toxic effects measured by morphology, release of lactate dehydrogenase, failure of the restriction of the passage of inulin, and incorporation of propidium iodide.
  
  
  RESULTS
  All solutions activated and killed mesothelial cells and PMN to some extent; the more concentrated the solution the greater the effect on these cells.
  
  
  CONCLUSIONS
  Lavage solutions both poison and stimulate mesothelial cells and neutrophils, and some solutions are more potent than others.
