title: Rupture point analysis of intestinal anastomotic healing in rats under the action of pure Copaíba (Copaifera Iangsdorfii) oil.
abstract: OBJECTIVE
  Analyze the mechanical strength of digestive tract scar after intestinal anastomosis surgery in animals treated with pure Copaíba oil.
  
  
  METHODS
  60 Wistar rats, male, about 250 days old and weighting around 350g were used. The rats were randomly divided into two groups: Group O, with 30 animals that received Copaíba oil and Group C, with 30 animals that received saline. Each group was subdivided into three subgroups, containing 10 rats each. They were designated O7, O14, O28, C7, C14 and C28, according to the post-operative assessment date at 7, 14 and 28 days, respectively. On these dates euthanasia was performed with the removal of the bowel segment containing the anastomosis and assigning the samples to tensile test for assessing Maximum Stress, Maximum Tensile Strength and Maximum Rupture Strength.
  
  
  RESULTS
  On the three variables of the study, the results indicate that, for the three assessment periods (7, 14 and 28 days) there was no significant difference between the oil and control groups.
  
  
  CONCLUSIONS
  For the mechanical tests proposed by this study, Copaíba oil didn t show any effectiveness in increasing the anatomosis strength.
