THE EFFECT OF ILEOCECAL VALVE REMOVAL IN A MODEL OF SHORT BOWEL SYNDROME.

Background: Short bowel syndrome is a harmful condition that needs experimental research.

Aim: To assess the impact of the ileocecal valve removal in a model of short bowel syndrome, in order to investigate the evolution of the colon under this circumstance.

Method: Fifteen Wistar rats were equitable divided into: Control (Sham), Group I (70% enterectomy preserving ileocecal valve) and Group II (70% enterectomy excluding ileocecal valve).

A study of the histological behavior of a rabbit vocal fold after a hyaluronic acid injection.

Unlabelled: The vocal fold structure is composed of tissues with many cells surrounded by the extra-cellular matrix. One of the most important components of the extra-cellular matrix is Hyaluronic Acid (HA). The aim of the study was to evaluate the inflammatory response of rabbit vocal folds after a local injection of Restylane HA.

Analysis of the effects of the interruption of the flow in the normal arterial endothelium morphology and the correlation with the ischemia duration in rabbits.

Unlabelled: The study of acute arterial insufficiency of the extremities is an area of continuing interest and investigation, in light of the possible effects stemming from the evolution of the disease and the necessity for urgent treatment.

Purpose: To analyze the effects of the interruption of the flow in the normal arterial endothelium morphology and correlate them with the ischemia duration.

Methods: We submitted 30 rabbits to the ligature of the right external iliac artery for 6 hours or 72 hours and observed specific morphological variables in the endothelial layer under optical and electronic microscopy.

Histologic behavior of the inflammatory process in autologous fat implantation in rabbit vocal folds.

Fat implantation in the vocal fold is described as a method of repairing vocal fold histostructural lesions that correlate with mucosal wave abnormalities. The aim of this study was to evaluate the histologic behavior of autologous fat implants. A fat block was implanted in pockets surgically created in the vocal folds of rabbits, and the inflammatory process induced was compared to the status of the contralateral vocal fold.
