[Healing process in bladder suture of rats with and without the administration of intraperitoneal Jatropha gossypiifolia L. gross extract].

BACKGROUND

The suture of tissues and their healing process is one of the basic fundamentals of surgery, and the research on substances which could improve the process is an ongoing challenge. The use of plants has been tested but till nowadays without scientific demonstration.

OBJECTIVE

To compare the macroscopic and histological alterations done by the use of intraperitoneal Jatropha gossypiifolia L. gross extract, in the healing process of sutures performed on the bladder of rats.

METHODS

Forty adult, male, Wistar rats were distributed into two animal groups. One centimeter longitudinal incision on the bladder ventral wall, and single plane synthesis with separated polyglactine 910 5-0 (Ethicon) stitches was done in all the animals. In the control group an intraperitoneal cavity instillation of distilled water at a ratio of 1 ml/kg/weight, and a 1 ml/kg/weight of Jatropha gossypiifolia L. extract for the Jatropha group was done representing 200 mg of the substance. Each group was subdivided into two with 10 animals in each, being submitted to euthanasia on 3rd and 7th post-operative days. Comparative histological, macroscopic and statistical analysis were undertaken between the subgroups.

RESULTS

Statistical significant difference was observed in the acute inflammation changes, vascular neoformation and bonding on day 3; the first one was greater in the control group, and the latter two greater in the Jatropha group; acute inflammation variables and fibroblastic proliferation presented to be more intense on day 7, with statistical significance favoring the control group.

CONCLUSIONS

No favorable healing effect was observed with the administration of single intraperitoneal dose of Jatropha gossypiifolia L. gross extract on the sutures of bladder in rats.
