title: Effects of contractubex on the prevention of postoperative peritoneal adhesion.
abstract: BACKGROUND
  There are numerus techniques and agents in use for reducing peritoneal adhesion formation. But in this research we believe this is the first research to reveal that contractubex (allium cepae, sodium heparin, and allantoin mixture) is reducing formed peritoneal adhesions. So it may be used to reduce the number of re-laparotomies/re-laparoscopies caused by peritoneal adhesions related complications.
  
  
  OBJECTIVE
  To evaluate the effects of contractubex (CT) in a rat model of postoperative peritoneal adhesion (PPA).
  
  
  METHODS
  Fifty rats were divided into four equal groups. In group 1, 1 g of CT was injected into the peritoneal cavity. In group 2, adhesions were generated. In group 3, adhesions were generated, and 1 g of CT was immediately applied into the peritoneal cavity. In group 4, adhesions were generated, and at postoperative d 7, 1 g of CT was applied into the peritoneal cavity. In group 5, adhesions were generated, and at postoperative d1, 3, 5, and 7, 1 g of CT was applied into the peritoneal cavity. The adhesions were scored both macroscopically and microscopically.
  
  
  RESULTS
  The mean macroscopic adhesion scores in groups 1-5 were 0 ± 0, 2.9 ± 0.21, 2.3 ± 0.54, 0.8 ± 0.63, and 2.2 ± 0.72, respectively (P < 0.0001); the mean microscopic values were 0 ± 0, 2.8 ± 0.42, 2.8 ± 0.42, 0.6 ± 0.52, and 2.3 ± 0.48, respectively (P < 0.0001). The mean macroscopic adhesion score in group 4 was lower than that in group 2 (P = 0.001). The mean macroscopic adhesion scores in groups 3 and 5 were higher than those in group 4 (P = 0.045 and P = 0.038, respectively) but did not significantly differ from those in group 2 (P = 0.171 and P = 0.124, respectively).
  
  
  CONCLUSIONS
  A single dose of contractubex did not prevent PPA formation but did diminish the amount of formed PPAs.
