Abstract
O presente trabalho teve como objetivo avaliar a influência de um suplemento
condroprotetor (nutracêutico) veterinário comercial, à base de sulfato de condroitina e
glucosamina, na reparação de falhas osteocondrais induzidas no côndilo femoral lateral de cães, por meio de análises clínica, radiográfica, macroscópica, histológica e
morfométrica. Objetivou-se ainda testar a segurança do produto, por meio dos exames
de glicemia, hemograma, funções hepática e renal, tempo de tromboplastina parcial
ativada e tempo de protombina. Foram utilizados 48 cães adultos, entre 10 e 25 kg de
peso corporal e sem raça definida, distribuídos aleatoriamente entre quatro tratamentos (I, II, III e IV), de acordo com o período de pós-operatório (15, 30, 60 e 90 dias) e contendo cada um deles 12 animais. Dentro de cada tratamento, seis animais (GI) receberam diariamente o condroprotetor, enquanto os outros seis constituíram o grupo controle (GII). Não houve diferença significativa entre os grupos de cada tratamento e, portanto, nas condições em que o presente estudo foi realizado, o condroprotetor não ocasionou efeitos adversos e o grupo tratado não diferiu do controle quanto ao processo de reparação dos defeitos.
The aim of this research was to evaluate the influence of chondroprotective veterinary supplement (nutraceutic) composed of glucosamine and chondroitin sulfate in the repair of osteochondral defects induced in femoral lateral condyle of dogs, by clinical, radiographic, macroscopic, histologic and morfometric analysis. We also aimed to test the safety of the supplement with tests of blood glucose, blood count, liver and kidney function, activated partial tromboplastine and time prothrombin time. Fortyeigth adult dogs with body weight ranging from 10 kg to 25 kg were used. They were divided into four treatments (I, II, III and IV), according to the postoperative period of evaluation (15, 30, 60 and 90 days) and each containing six animals. Within each treatment, six animals (GI) received the supplement daily, while the other six formed the control group (GII). No significant differences were observed between groups for each treatment. Therefore, the conditions in which this study was conducted, the chondroprotective did not cause adverse effects and the treated group did not differ from the control on the repair process of such defects.
