Influence of leukotriene inhibitor montelukast on wound contraction and cutaneous healing process in rats.

Background: Wound contractures can cause severe deformities and disabilities. Recent studies have suggested that leukotriene receptor antagonists have an inhibitory effect on the healing contraction process. This study aimed to evaluate the influence of the leukotriene inhibitor montelukast on the cutaneous healing process and the wound contraction phenomenon in rats.

Evaluation of molar teeth and buds in patients submitted to mandible distraction: long-term results.

Background: Despite all benefits offered by mandible distraction, complications and long-term consequences need to be evaluated to define its safety and morbidity. Forty mandible distractions were studied. Panoramic mandible radiographs obtained preoperatively, during distraction, and during the postoperative period were reviewed, with the intention of evaluating development and complications of molar buds and teeth in the distraction area.

Endoscopic periosteal brow lift: evaluation and follow-up of eyebrow height.

Background: Endoscopic brow lift has become widely accepted as a method for rejuvenation of the upper third of the face, mainly to achieve eyebrow elevation. In this study, the authors quantified eyebrow elevation after videoendoscopic subperiosteal technique and followed up the heights of the eyebrows at different postoperative intervals.

Methods: Seventy-two patients were submitted to endoscopic subperiosteal brow lift, and photographic evaluation was performed preoperatively and at different intervals postoperatively.

[Surgical bladder wounds treated with Orbignya phalerata aqueous extract: controlled study in rats].

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.

Oral glutamine does not prevent bacterial translocation in rats subjected to intestinal obstruction and Escherichia coli challenge but reduces systemic bacteria spread.

Objective: We investigated whether oral glutamine prevents bacterial translocation.

Methods: Male Wistar rats were fed with isocaloric and isoproteic standard rat chow and randomly assigned to receive glutamine (GLN) or glycine administered through an orogastric tube at 1.5 g.
