ABSTRACT
Alterações morfológicas de 11 casos de cães com insuficiência renal foram caracterizadas e classificadas de acordo com os padrões estabelecidos pela Organização Mundial de Saúde para seres humanos. Glomerulonefrite esclerosante difusa foi diagnosticada em 82,0 por cento dos animais e nefrite intersticial crônica nos 18,0 por cento restantes. Os tipos e freqüência das lesões identificadas foram similares às encontradas na literatura para a insuficiência renal crônica.
Morphologic alterations of 11 cases of dogs with renal failure were characterized and classified according to the patterns established by the World Health Organization for human beings. Diffuse sclerosing glomerulonephritis was diagnosed in 82.0 percent of the animals and chronic interstitial nephritis in the remaining 18.0 percent. The types and frequencies of lesions were similar to the those noticed in the literature for chronic renal failure.

The aim of this study was to evaluate the effect of snake venom derived fibrin glue on the healing of the deep digital flexor tendon, during three periods. The tendon of the 2nd digit of 30 thoracic limbs of dogs was partially sectioned for glue application. Biopsies were performed 7, 15, and 30 days post surgery for the clinical and morphological study of tendons. Analysis of the results showed that 73.3% of the tendons showed stump retraction and 16.6% moderate to excessive adherence, which affected sliding. There was a significant difference in the number of inflammatory cells among the three studied periods, being the highest on day 15. The morphological analysis revealed a typical tendon healing process with a lower level of inflammation in the acute phase, facilitating the cicatricial maturation phase.

The aim of this study was to evaluate the effect of snake venom derived fibrin glue on the strength of tendon healing in dogs. The deep digital flexor tendon of the 5th digit of 24 thoracic limbs was partially sectioned for adhesive application. On the 7th, 15th, and 30th postoperative day tendons segments were removed for the clinical and biomechanical study. Results indicated that 62.5% of the tendons showed stump retraction and 20.8% moderate to excessive adherence, which affected gliding. The biomechanical evaluation showed that, over time, tendon healing gained progressive resistance for maximum traction and permanent deformations with satisfactory results on the 15th day for rigidity and resilience compared to the other two studied periods.
