Ceratomicose em equinos Ciência Rural
Galera,Paula Diniz; Martins,Bianca da Costa; Laus,José Luiz; Brooks,Dennis.
O cavalo, dado o seu meio ambiente, está sujeito a afecções frequentes da córnea e da conjuntiva, tecidos oculares bastante expostos a bactérias e fungos, principalmente Aspergillus spp. e Fusarium spp. As ceratites ulcerativas bacterianas e fúngicas, bem como as ceratites fúngicas não ulcerativas, caracterizadas principalmente pelo abscesso estromal, são frequentes nessa espécie. Ocorrida a lesão inicial, perpetua-se um ciclo vicioso, com liberação de citocinas inflamatórias, que desencadeiam uma rápida e severa infiltração corneal por células polimorfonucleares. A córnea torna-se sujeita à destruição por enzimas proteolíticas liberadas pelos micro-organismos e por células inflamatórias, capazes de desencadear a dissolução estromal e a perfuração do bulbo...

Lesões isquêmicas do testículo de cães mediante garroteamento temporário do cordão espermático Ciência Rural
Ferreira,Affonso Luiz; Crisci,Ana Rosa; Fiorani,Segundo Amarillis Salize; Laus,José Luiz; Jorge,Adriana Torrecilhas.
No homem, considera-se emergência urológica a isquemia decorrente de torção testicular. Há controvérsias quanto ao tempo necessário para causar morbidade ou reversibilidade das lesões isquêmicas das células germinativas. Este estudo realizado em cães tem como objetivo determinar o período crítico do aparecimento e a reversibilidade das lesões após garroteamento do cordão espermático. Os resultados mostraram que duas horas é o período crítico de sobrevivência das células germinativas à isquemia. Após 60 dias, houve recuperação completa do epitélio germinativo. Animais com período de isquemia de 2h 30min, examinados após 60 dias, apresentaram necrose testicular.

Bilateral lamellar keratoplasty in descemetocele treatment in dog with botulism by use of equine renal capsule and conjunctival pedicle graft Ciência Rural
Laus,José Luiz; Galera,Paula Diniz; Schocken-Iturrino,Ruben Pablo; Cavassani,Marluce de Macedo; Andrade,Alexandre Lima de.
A 3-year-old, male mixed breed dog with botulism and bilateral descemetocele was submitted to lamellar keratoplasty with equine renal capsule preserved in glycerin in the right eye and conjunctival pedicle graft in the left eye. The evolution was satisfactory in both eyes, but better in the eye receiving the equine renal capsule, because the corneal transparence was more evident in that eye. On the other hand, the surgical period was more quickly in the eye receiving the equine renal capsule because the preparation of the conjunctival pedicle before the keratoplasty was not necessary.
