Abstract

FERREIRA, Eduardo de Castro et al. Surgical blader wounds treated with Orbignya phalerata aqueous extract: controlled study in rats. Acta Cir. Bras. [online]. 2006, vol.21, suppl.3, pp.33-39. ISSN 1678-2674.  https://doi.org/10.1590/S0102-86502006000900006.

INTRODUCTION: Wound healing is a complex process that deals with different biological and immunological systems and is essential to keep the organism integrity. Three well-defined phases occur: inflammatory, proliferative and maturation. A failure or lengthy phase may result in a delay or absence of it. PURPOSE: The aim of this paper is to analyse comparatively the histological alteration provided by the use of the aqueous extract of Orbignya phalerata, in the healing process of bladder surgical wounds. METHODS: Forty adult, male Wistar rats were used. The experimental procedure consisted of a longitudinal 2cm long bladder incision and single layer interrupted suture of 5-0 poliglactine 910. Post-operatively, the rats were randomly divided into two groups of 20. The substance was not used in the control group. The Orbignya phalerata aqueous solution was used in the study group. The animals were observed and killed three and seven days later. Comparative histological analysis was accomplished between the groups. Resuts: Significant statistical differences were observed in the neo-formation variables (p= 0,001), chronic inflammation (p= 0,002) and fibroblastic proliferation (p= 0,023). Acute inflammation was very evident in the control group. CONCLUSION: The time factor of wound healing showed homogeneity between experimental and control groups, however faster in the experimental one. The Orbignya phalerata had a favoring healing effect in the surgical incision on rats bladder.
