Abstract

SASSIOTO, Maria Cristina Pita; INOUYE, Celso Massaschi; AYDOS, Ricardo Dutra  and  FIGUEIREDO, Arthur Silveira de. Bone repair in rats treated with sodic diclofenac and calcitonin. Acta Cir. Bras. [online]. 2006, vol.21, suppl.4, pp. 40-44. ISSN 1678-2674.  http://dx.doi.org/10.1590/S0102-86502006001000010.

PURPOSE: To investigate clinical and histologically the bone repair in treated animals with calcitonin and sodic diclofenac. METHODS: Ninety-six femoral defects were created in forty-eight animals distributed in four groups (n=24): either left untreated, treated with the sodic diclofenac or calcitonin or both. Follow-up was 7, 14 and 21 days. Histological sections stained by haematoxylin-eosin was observed under light microscopy (100X) and quantitatively scored for their trabecular formation. The groups and subgroups were compared being used the Kruskall-Wallis test. RESULTS: Smaller trabecular formation was observed in the animals of the group II and larger trabecular formation in the animals of the group III. Was found significant differences in the comparison between all the groups (Kruskall-Wallis, p <0.05). CONCLUSION: The obtained data suggest that the bone repair is a time-dependent process, which can be delayed by the sodic diclofenac and accelerated by the calcitonina, when used separately. The associated use of calcitonina and sodic diclofenac didn't show to be the best therapeutic option in the treatment of bone defects surgically created.
