| Osteosarcoma is defined as a bone matrix-producing malignant mesenchymal tumor. It is relatively rare among domestic animals, but corresponds to 85% of all malignant bone tumors in dogs. To study canine osteosarcoma in animals living in Brazil and correlate the clinical-morphological findings with prognosis, forty-six cases of dogs with osteosarcoma were studied retrospectively out of a total of 56 malignant primary bone tumors on file. The animals were assessed in terms of age, sex, breed, topographic tumor distribution, and presence of metastases at diagnosis. The tumors were classified histologically by the method of Pool¹. Osteosarcomas corresponded to 82% of primary malignant bone dysplasias in the sample studied. Age ranged from 6 months to 14 years... |

| Twelve adult male Wistar rats (220 g average weight) were divided in 3 experimental groups: GI -15. GII 30 and GIII 60 days, after mandibular molar extraction, with three experimental animals and one control per group. Qualitatively, ultrastructural changes of protein filaments from myofibrils of these muscles and ipsilateral to the extractions were observed. Ultrastructure asymmetry and disorganization of Z line and I band, in the experimental group GII, of Medial Pterigoid muscle (MPT) were observed. The temporomandibular dysfunction, stimulated by the unilateral extractions of mandibular molars in rats may lead to modifications in the Z line and I band, which showed to be sensitive to this dysfunction. Changes in the MPT muscle, probably related to... |
