A laminite é uma doença podal grave que acomete os equídeos, sendo responsável por intenso sofrimento. Neste estudo foram pesquisadas a presença de calprotectina por meio da imunoistoquímica, e de lipocalina associada à gelatinase de neutrófilos (NGAL), por zimografia, no tecido laminar do casco de equinos após obstrução intestinal. Os animais foram divididos em quatro grupos: Grupo controle (Gc), contendo sete animais normais, sem procedimento cirúrgico; Grupo Instrumentado (Gi), contendo cinco animais, os quais passaram por todo o procedimento cirúrgico sem sofrerem obstrução intestinal; Grupo Não Tratado (Gnt), contendo quatro equinos submetidos a obstrução intestinal do jejuno por distensão de balão intraluminal, sem tratamento; e Grupo Tratado (Gt), contendo quatro equinos submetidos a obstrução intestinal, e tratados preventivamente com hidrocortisona. Houve imunomarcação de calprotectina em todos os grupos experimentais, com aumento nos equinos do grupo distendido em relação ao Gc. Com relação ao NGAL, houve aumento também do Gnt e do Gi em relação ao Gc. O Gt não diferiu dos demais. Conclui-se que a distensão do intestino delgado pode promover acúmulos de leucócitos nos cascos de equinos e que o NGAL é um método viável para se detectar infiltração neutrofílica em equinos. Novos estudos deverão ser realizados para se verificar possível benefício anti-inflamatório da hidrocortisona no casco de equinos com obstrução intestinal.

The aims of the present study were to propose a PCR-RFLP genotyping method for the AJ_315378:c.110A>G and AB_264325:c. 771G>C SNPs in the equine CRISP1 and HTR1A genes, respectively, as well as to characterize these and another polymorphism, AB_098561:c.1470G>A of the SLC6A4 gene, in order to provide a basis for future studies investigating the association between DNA markers and traits of interest in this breed. For this, 151 Mangalarga horses of both sexes, representatives of the population of the Sate of São Paulo, Brazil, were used. PCR-RFLP was found to be adequate for the genotyping of the SNPs AJ_315378: c.110A>G of the CRISP1 and AB_264325:c.771G>C of the HTR1A. However, the polymorphism of the CRISP1 probably does not occur in Mangalarga horses, a fact impairing association studies of this marker with traits related to male fertility. The estimative of the population genetic parameters obtained for the polymorphisms AB_264325:c.771G>C of the HTR1A and AB_098561:c.1470G> A of the SLC6A4 in the studied sample discourage the conduct of research addressed the association between markers and traits related to temperament.

Biochemical values are widely related with environmental agents, sex and age, and are used in disease diagnosis. Numerous reports have been published on the biochemical parameters of different breeds of horses. However, there is a paucity of information concerning Cu-Zn superoxide dismutase (SOD), ceruloplasmin, copper and zinc determinations in the serum. Blood samples from a total of 60 horses of the Mangalarga-Paulista breed, representing three age groups (0 to 4 months old, 6 to 18 months old and adult) were examined. Male horses have a higher mean value of SOD, ceruloplasmin and copper than do females. No significant sex-related difference was observed in serum zinc content of weaned and adult horses. SOD activity was significantly higher in adult animals. Since SOD has a protective effect against superoxide free radical toxicity and possesses anti-inflammatory activity, it is reasonable to assume that the increased activity of this enzyme may be due to an adaptation mechanism which protects the adult animal against oxygen toxicity.

Chronic hypertrophic pododermatitis cases in six horses of different breeds, aging 14 months to 19 years are described. The lesion begun with a infiltrative tissue in the frog and sole regions of the hoof, characterized by a fast and disorganized growth, with a papillary aspect, white colored in the roots and dark on the extremity, with a necrotic secretion and an extremely fetid odor. Microscopically, an exuberant epidermic proliferative tissue was observed, intermingled with little connective tissue. The horses were divided into two treatment groups. In the first group, including three young mares and a foal, showing lesions in only one limb, a surgical resection of the invasive mass was performed, followed by cauterization of the remaining edges and subsequent daily local application of antiseptic substances. In three of these horses, recurrence of the initial lesion occurred, with fast growth of hyperplasic tissue, affecting almost all the frog and half of the sole. Two horses developed contraction deformities of the hoof. In the second group, one male and one female, each with lesions in two limbs, after surgical debridement of the tissue, the animals received daily applications of picric acid 5%, associated to local use of oxitetracyclin. Although one of these cases required a second surgical intervention for removal of the mass, the horses showed after a period of two to three months total absence of the infiltrative tissue. The use of local picric acid 5% and oxitetracyclin associated to previous surgical debridement showed to be more efficient than the use of antiseptic substances in the treatment of chronic hypertrophic pododermatitis.

The objective of this study was evaluate the airways' cells types from horses of the military police of Federal District. It was used 24 horses, divided into 2 groups of 12: group I - animals in policy activity and group II - animals out of policy activity. At the inspection, physical exam and blood exam, the results agreed with no present clinical pathologies. It was infused 240mL of saline solution in the bronchoalveolar wash. In the bronchoalveolar wash, the group I registered 25.25±7.3 squamous cells, 20.2±5.5 epithelial cells, 22.2±6.23 macrophages and 2.02±5.77 erythrocytes, and in the group II, it was observed 31.0±9.47 squamous cells, 19.0±5.20 epithelial cells, 43.0±13.88 macrophages, 4.0±1.52 eosinophile and 3.0±1.0 erythrocytes. Verifying the occurrence of side effects after the experiment, there was no problem from the used technique.
