13. Comparação da atividade de proliferação celular nos fibromas odontogênicos e ossificantes
Central (COF) and peripheral (POF) odontogenic fibroma are benign odontogenic tumours. Peripheral ossifying fibroma (PEOF) is a non neoplastic reactive lesion. Central ossifying fibroma (CEOF) is a benign neoplasm fibro-osseous lesion. The aim of this study was to evaluate comparatively the cellular proliferative activity in these lesions.

14. Ossifying pulmonary granulomatosis due to larvae of ascaris
A unique case of ossifying pulmonary granulomata is described in which the presence of larvae of Ascaris lumbricoides within the granulomata was demonstrated by means of immunofluorescence.

16. Massive juvenile ossifying fibroma of maxillary sinus with orbital involvement.
A 14-year-old black girl had painless, progressive proptosis and upward displacement of the left eye for approximately six months. Computed tomography showed a massive tumour involving the maxillary sinus with extension into the sphenoid sinus, ethmoid sinus, and orbit. The mass was excised surgically and proved histopathologically to be a juvenile ossifying

17. Ameloblastic odontoma in the mandible of a llama
A 4-year-old llama had an aggressive, multiloculated, expansile bone lesion involving the rostral mandible. The mandibular lesion was imaged using radiography and computed tomography. Antemortem diagnosis of an ossifying fibroma was made histologically. Postmortem findings showed the lesion to be limited to the mandible. Final diagnosis was ameloblastic odon

18. Malignant myositis ossificans: occult gastric carcinoma presenting as an acute rheumatic disorder.
A patient developed ossifying skeletal muscle metastases from a primary gastric mucin-producing adenocarcinoma. The unusual nature of skeletal muscle metastases and the inflammatory-like syndrome associated with heterotopic ossification is reviewed. It is suggested that this case of 'neoplasm-induced post-traumatic myositis ossificans' may be caused by the i

19. Parathyroid carcinoma in familial hyperparathyroidism.
Two families with hereditary hyperparathyroidism are described. One member of each family developed a parathyroid carcinoma. In one case this recurred locally and metastasised. This patient showed hyperplasia of one of the three other parathyroid glands. It is possible that the different parathyroid lesions found in familial hyperparathyroidism may be the re

20. Effects of interleukin-1 on syntheses of alkaline phosphatase, type X collagen, and 1,25-dihydroxyvitamin D3 receptor, and matrix calcification in rabbit chondrocyte cultures.
The effect of IL-1 on expression of the mineralization-related phenotype by chondrocytes was examined. In cultures of rabbit growth plate chondrocytes, IL-1 beta at 0.1 ng/ml caused 95% decreases in alkaline phosphatase activity, alkaline phosphatase mRNA levels, the incorporation of 45Ca into insoluble material, and the calcium content during the hypertroph

21. The effect of neonatal treatment of male mice with antiandrogens and of females with androgens on the development of the os penis and os clitoridis.
The os penis in mice and rats is composed of a proximal intramembranous and endochondral osseous element and a distal cartilaginous, ossifying element. Female mice, but not rats, have a small os clitoridis which corresponds to the intramembranous part of the proximal element of the os penis. In mice of either sex a dense mesenchymatous formation ventral to t
