ABSTRACT The aim of this study was to characterize the tissue reactions triggered by the polypropylene mesh coated with chitosan and polyethylene glycol film, and if it’s able to prevent the formation of peritoneal adhesions. Defects in the abdominal wall of rats were induced and polypropylene meshes coated with chitosan/polyethylene glycol (CPEG group, n= 12) and uncoated (PP control group, n= 12) were implanted. On the fourth and forty-fifth postoperative day the formation of adhesion and the tissue reaction to the biomaterial was evaluated through histological and histochemical analysis. The area (P= 0.01) and severity (P= 0.002) of the adhesion was significatively less in the CPEG group. On the fourth day the foreign body reaction was less intense in...

Double-setting alpha-tricalcium phosphate cement provided with interconection channels in rabbits after enucleation: A potential implant for the anophthalmic socket
Provedor de dados: 45

The purpose of this study was to evaluate the macroscopy and microstructure of a double setting alpha-tricalcium phosphate bone cement sphere provided with interconnection channels (alpha-TCP-i), as well as the integration of the implant with the rabbits' orbital tissue, through macroscopic analysis and histopathology. The external and internal surfaces of the alpha-TCP-i were evaluated macroscopically and by electron microscopy. Twelve New Zealand rabbits received 12mm implants of alpha-TCP-i following enucleation of the left eye. The clinical assessment was undertaken daily during the first 15 days, followed by fortnightly assessment until the end of the study period. For the morphological analysis, exenteration was performed in 3 animals per...

Use of methyl methacrylate, moulded in its paste phase, to fill the orbital cavity of dogs, after exenteration in cases of ophthalmic neoplasias: a report of three cases
Provedor de dados: 65

Methyl methacrylate, acrylic resine for odontologic use, was used to fill the orbital cavity of three dogs which presented retrobulbar, eyeball and eyelid neoplasias extended to the orbital space, respectively. The material was moulded in the orbit before polymerization, while still in its paste phase. In each case, follow-up reports were obtained in the 10th and 40th days and in 18 months after surgery. Complications were not observed and improvement of cosmetic appearance was obtained.
