title: Hypertonic glucose solution 10%-25% on the mesenterium and peritoneum of the rat: macroscopic and microscopic study.
abstract: OBJECTIVE
  The objective of the experimental study is to detect the macroscopic and microscopic alterations of the mesenterium and parietal peritoneum when hypertonic glucose aqueous solution 10%-25% is administrated into the peritoneal cavity of the rat.
  
  
  METHODS
  90 Wistar females young rats adults were used weighing between 180-250 g, numbered 1 to 90, establishing unique group and divided in three groups (A, B, C) of 30 animals chosen aleatory manner. 0.9% saline solution was used called control group, or group A, 10% glucose solution named group B, and in the others 30 was used 25% glucose solution named group C, differing in the observation period, (06 h, 24 h and 48 h), but with the same procedure. A midline abdominal wall laparotomy was made and in the animals of the control group was injected 2 ml of a 0.9% saline solution into the peritoneal cavity. After, we made a suture in mass without to include the peritoneum. For the others groups (B, C) the rats received 10% glucose solution and 25% glucose solution injected into the peritoneal cavity respectively. All groups were kept under observation and the results were submitted to statistical analysis by a longitudinal and transversal comparative study.
  
  
  RESULTS
  A new surgery was done in 6 h, 24 h and 48 h, and we observed in macroscopic evaluation, the presence of fluid, serous uniform and rosy all over the cavity. Vascular congestion was present. We dried out 90 fragments of mesenterium and 90 fragments of parietal peritoneum bilateral. In the microscopic study, necrosis was not present. For the mesenterium histological study we observed 16 cases (17.8%) unspecific chronic inflammation, 30 cases (33.4%) hyperplasc linfonod, 10 cases (11.1%) high vascular congestion, 6 cases (6.6%) reaction fibrosis and 28 cases (31.1%) no alteration. For the parietal peritoneum histological study we observed 6 cases (3.3%) reaction fibrosis and 174 cases (96.7%) no alteration. Giant cell was not present. In the statistical analysis statistic there is no significance between the groups (p>0.05).
  
  
  CONCLUSIONS
  Hypertonic glucose solution and NaCl 0.9% on the mesenterium and parietal peritoneum do not produce tissue necrosis in a rat and the inflammation process has the same intensity.
