Uso da flunixina meglumina tópica no tratamento de uveítes em cães

Este trabalho teve por objetivo comparar o efeito (uso tópico) da flunixina meglumina e da dexametasona no controle da uveíte anterior em cães, por meio de avaliação clínica e pela dosagem de proteínas no humor aquoso. Foram utilizados 17 cães portadores de uveíte anterior de diversas etiologias. Os animais, divididos em dois grupos, foram tratados durante 15 dias. Observou-se maior eficácia da flunixina meglumina na cura clínica das uveítes e na redução significativa da concentração de proteínas no humor aquoso em relação à dexametasona. Concluiu-se que a preparação comercial de uso parenteral pode ser utilizada como colírio no tratamento de doenças inflamatórias da úvea.

Avaliação hematológica de cães naturalmente infectados por Leishmania (Leishmania) chagasi submetidos a tratamento com antimoniato de meglumina

The present research was carried out aiming to assess the hematological response of dogs with visceral leishmaniasis submitted to treatment. For this, seven animals naturally infected by Leishmania sp. were submitted to a treatment with 75 mg/kg meglumine antimoniate subcutaneously, 12-12h/3 weeks. In all animals, a complete blood count and bone marrow aspiration biopsy were carried out for a descriptive evaluation at up to seven moments: before the treatment, 30, 60, 90, 120, 150 and 180 days after the start of the treatment. Before the beginning of the experiment hematological alterations were observed in four of the seven dogs (57.1%), among them, nonregenerative anemia, lymphopenia, lymphocytosis and monocytosis. During the course of the experiment the occurrence of leukocytoses, such as left shift neutrophilia and eosinophilia, were observed in some of the animals. Before the beginning of the treatment (M1), the occurrence of erythrocytic hypoplasia was detected by bone marrow cytology in two of the dogs (28.6%). This was reversed through an increase in the amount of erythroid progenitor cells after the administration of meglumine antimoniate. Thus, it can be concluded that the treatment led to normalization of the hematological alterations and recovery of the bone marrow.

Avaliação clínica e parasitológica de cães naturalmente infectados por Leishmania (Leishmania) chagasi submetidos a tratamento com antimoniato de meglumina e alopurinol

Aiming to assess the efficacy of the treatment, to verify the occurrence of possible disease relapses and to search for the presence of parasites after the treatment, seven dogs naturally infected by Leishmania sp., were submitted to a treatment with meglumine antimoniate and allopurinol. For this, lymph node and bone marrow aspiration biopsies were carried out at seven moments. After the end of the six-month observation period all dogs were submitted to euthanasia. Then, spleen and liver imprints and in vitro cultures were carried out to search for amastigote forms of the parasite. All animals presented remission of the symptoms and during all the observation period no dog presented relapse of the disease, although amastigote forms of the parasite were observed in two of the animals at the end of the experiment. Thus, it was possible to conclude that the treatment promotes clinical healing but it does not eliminate the parasites completely.

Leucograma e metabolismo oxidativo dos neutrófilos de cães com leishmaniose visceral antes e após o tratamento com Antimoniato de Meglumina e Alopurinol

Leukogram and neutrophil oxidative metabolism from dogs with visceral leishmaniasis (VL) were compared before and after treatment with meglumine antimoniate (AM) and with an association of meglumine antimoniate and allopurinol (AMA). The results obtained demonstrated that neutrophils of dogs with VL do not lose their capacity of reducing NBT and that oxidative metabolism has been more active in the majority of the cases. After treatment with AM and AMA, dogs with VL presented a redution of neutrophils oxidative metabolism, suggesting that this decrease was related with the decrease in the number of parasites and a probable inhibitor effect of these drugs on neutrophils oxidative metabolism.
