ABSTRACT The medium for storing biological tissues is of great importance for their optimal use in surgery. Glycerin has been proven efficient for storing diverse tissues for prolonged time, but the preservation of the bovine amniotic membrane in glycerin 99% at room temperature has never been evaluated to be used safely in surgical procedures. This study evaluated the preservation of 80 bovine amniotic membran...
The study aimed to evaluate biocompatibility, osteoconduction and osseointegration of a pasty composite of hydroxyapatite (20%) and lignin (80%) as a promoter of metal implant and bone tissue integration. An intramedullary Schanz pin was implanted in both tibias of fifteen bitches. In the left tibia, the pin was coated with the biomaterial at the time of surgery. Marrow cavity was also filled with the biomateri...
The aim of this study was to evaluate the effects of canine amniotic membrane, previously preserved in glycerin, used as a patch on the repair of experimentally-made superficial corneal ulcers and to compare corneal epithelization between the treated and non-treated groups. Xenogeneic amniotic membranes were collected aseptically and preserved in 99% glycerin at room temperature. Each animal was anesthetized an...
Among the proposed treatments to repair lesions of degenerative joint disease (DJD), chondroprotective nutraceuticals composed by glucosamine and chondroitin sulfate are a non-invasive theraphy with properties that favors the health of the cartilage. Although used in human, it is also available for veterinary use with administration in the form of nutritional supplement independent of prescription, since they h...
Os eventos que fazem parte do processo de reparação de lesões da córnea ocorrem simultaneamente e envolvem proliferação, migração, diferenciação e apoptose celular, além da comunicação intercelular. Vários fatores solúveis, além de proteínas da matriz mesenquimal, proteoglicanos, enzimas proteolíticas e alguns tipos celulares são abordados nesta revisão, na qual explicam-se os processos de reparação de lesões s...
The tear film plays an important role in maintaining the integrity of the ocular suface. During general anesthesia, tear production is considerably reduced, which requires care to prevent adverse effects that result in diseases of these structures. Studies comparing the effects of induction of anaesthesia with thiopental and propofol on tear production have not been carried out yet. Because these drugs are used...
In this work, biocompatibility, osteointegration, osteoconductivity, and biodegradation of a hydroxyapatite polyhydroxybutyrate new composite were evaluated. The composite was implanted in rabbits' bone defects and clinical, radiographic, histological, and histomorphometric data of these animals were compared with those of unfilled defects on the days 8th, 45th, and 90th after surgery. No significant difference...
O presente estudo avaliou a influência do plasma autógeno rico em plaquetas (PRP), associado ou não ao autoenxerto esponjoso (EOE), na reparação de falhas ósseas criadas no crânio de coelhos. A falha I foi preenchida com o PRP; a falha II com 3mg de EOE; a falha III com EOE associado ao PRP e a falha IV não foi preenchida, servindo como controle. Após as cirurgias, os animais foram separados em três grupos e eu...
A biocompatibilidade, a osseointegração e a reabsorção de compósitos contendo 10% de hidroxiapatita (HAP-91®) e 90% de polihidroxibutirato foram analisadas após implantação em defeitos ósseos em coelhos. Foram obtidos dados clínicos, radiográficos, histológicos e histomorfométricos aos oito, 45 e 90 dias após a realização da cirurgia, sendo os resultados comparados aos de defeitos não-preenchidos. Não foram obs...
