Solução hipersaturada de sal ou de glicerina a 98% como conservantes de centros frênicos caninos utilizados na reparação de defeitos musculares em ratos wistar

Aiming to evaluate the over saturated salt solution (1.5g commercially available salt in 1.5ml of tridestilled water) as tissue conservator of the canine frenic center and to compare its conservator potential with the well-established glycerin 98% conservator solution, peaces of this tissue were implanted to repair produced muscle lesions in 28 Wistar rats. Previously both solutions had been tested for bacterial and fungal contaminations, both exams with negative results. In each experimental animal, lesions were made in both Rectus abdominis muscles and repaired with the tissue preserved in both solutions. The animals were divided in seven groups and sacrificed in three, five, seven, 10, 15, 30 and 60 days after reparation for histological evaluation of the implanted region. In macroscopic exam the complete substitution of the implants by live tissue was observed, without rejection of the implanted tissue. In the microscopic evaluation we observed that the substitutions were made by fibrous conjunctive tissue deposition. At the end of the evaluation period, the implanted membranes were not present in repaired regions. In both conserved tissues there were not differences in tissue reactions. The over saturated salt, and 98% glycerin solutions presented similar results in the canine frenic center preservation indicating that both solutions may be utilized to preserve this membrane.

Limbal autograft transplantation in a dog with alkali-induced ulceration

Descreve-se um caso de um animal da especie canina, femea, sem raca definida, de tres meses de idade, com historico de apatia, contato previo com produto alcalino (hidroxido de sodio) e relutância em abrir o olho direito. Ao exame oftalmico, foram observados blefarospasmo, fotofobia, epifora, quemose discreta, hiperemia conjuntival, e edema corneal difuso com comprometimento do limbo. Foram realizados o teste da fluoresceina positivo e o Teste Lacrimal de Schirmer 32mm min-1. Com base nos achados, firmou-se o diagnostico de ulcera por alcali e realizou-se transplante autogeno do limbo. No pos-operatorio, observou-se vascularizacao corneal a partir do terceiro dia e sua intensificacao, em numero e calibre, nos dias subsequentes. Tambem foram observadas minimas areas de transparencia corneal. Os resultados obtidos permitem admitir que o transplante autogeno de limbo e procedimento factivel para o manejo da terapia de ulceras de cornea por alcali.

Hérnia peritoneopericárdica em cão

A male, five years old mongrel dog weighting 23kg, was refered presenting periodic digestive disturbs and dispnoea. A descompensated peritoneopericardical hernia was diagnosticated and a voluminous content (distended stomach, two liver lobes, partial spleen and a segment of the duodenum with pancreas) was reduced. The diaphragm and pericardium were sutured simultaneously with poliglactin 910. The animal had a complete postoperative recovery without complications.
