HISTOLOGIC ALTERATIONS OF THE BASEMENT MEMBRANE OF THE DERMAL AND EPIDERMAL LAYERS OF THE HOOF IN HORSES WITH ACUTE LAMINITIS
Provedor de dados: International Journal of Morphology
Autores: de Lima Sampaio,Rita de Cássia; Canola,Julio Carlos; de Lacerda Neto,José Corrêa; de Moraes,Julieta Rodini Engrácia.
The morphological characteristics of the hooves of two groups of horses were studied. The first group was comprised of six adult animals without any treatment and served as the control. The other group, comprised of seven horses, received carbohydrates overload orally. Of these, 71% developed laminitis between 36 and 48 hours after carbohydrate administration. After 48 hours of induction, the animals were sacrificed and their fore limbs and hindlimbs were removed for histologic study. Tissue sections 5 to 7 µm thick were obtained, stained with hematoxylin-eosin (H&amp;E) or periodic acid Schiff's (PAS), and then examined by light microscopy. It was possible to identify in horses from the laminitis group, morphological and structural changes in the...

Characteristic findings of magnetic resonance imaging (MRI) and computed tomography (CT) for severe chronic laminitis in a thoroughbred horse
Provedor de dados: Obihiro University of Agriculture and Veterinary Medicine Academic Repository (OAK)
Autores: Yamada, Kazutaka; Inui, Tomohiro; Itoh, Megumi; Yanagawa, Masashi; Sato, Fumio; Tominari, Masataka; Mizobe, Fumiaki; Kishimoto, Miori; Sasaki, Naoki.
A Thoroughbred horse with severe chronic laminitis of both forelimbs was evaluated on the same day with magnetic resonance imaging (MRI) and computed tomography (CT). Both MRI and CT revealed loss of the dorsal aspect of the cortical bone of the 3rd phalanx and sclerosis. CT reflected the status of the horny layer and bone of the affected feet, while MRI depicted inflammation of the laminar corium, together with tendon edema. On the 3-dimensional CT venogram, vessels were visualized in both the right and left forelimbs, although there was a difference in the vasculature of the coronary plexus and circumflex vessels between the right and left forelimbs. A combination of both MRI and CT provides detailed information regarding pathological conditions. © 2017...

Equine metabolic syndrome in Colombian creole horse: case report
Provedor de dados: Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Autores: Castillo,C.A.; Jaramillo,C.; Loaiza,M.J.; Blanco,R.
ABSTRACT The equine metabolic syndrome is a condition that can be recognized because of obesity, insulin resistance and laminitis. Genetic factors could play a role in the occurrence of this syndrome. Certain breeds such as ponies (including the South American creole horses) have a lower sensibility to insulin and a higher prevalence of hyperinsulinemia. The environment and management conditions, such as overfeeding and lack of exercise are factors that bring a propensity for obesity. The adipose tissue works as an endocrine organ producing hormones (adipokines or adipocytokines) that affect the horse´s metabolism. The objective of this report is to describe the first case report of a Colombian creole mare with a metabolic syndrome, diagnosed by means of...

Morphological abnormalities and apoptosis in lamellar tissue of equines after intestinal obstruction and treatment with hydrocortisone
Provedor de dados: Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Autores: Laskoski,L.M; Valadão,C.A.A; Vasconcelos,R.O; Souza,A.H; Faleiros,R.R; Amorim,R.L.
Four experimental groups of equines were used in order to study morphological abnormalities and apoptosis in lamellar tissue. Group Cg (control) was composed of animals without any surgical procedure; group Ig (instrumented), animals that underwent enterotomy; group Tg (treated), animals that were subjected to intestinal obstruction and were treated with hydrocortisone; and group Ug (untreated), animals that were subjected to intestinal obstruction without treatment. The lamellar tissue was analyzed regarding the presence of tissue abnormalities and apoptosis. No morphological abnormalities were observed in animals of surgical groups, and no difference in apoptosis was observed between groups. It was concluded that intestinal obstruction allowed laminitis...

Histopathological hoof laminar changes in horses with Pituitary Pars Intermedia Adenoma: cases report
Provedor de dados: Arquivo Brasileiro de Medicina Veterinária e Zootecnia
Autores: Laskoski,L. M.; Dittrich,R. Locatelli; Valadão,C. A. A; Castro,M. L.; Araujo,F. F.; Silva,J. R.; Basso,F. Z.; Dornbusch,P. T.; Deconto,I.; Sousa,R. S.
ABSTRACTLaminitis in horses is often associated with endocrine disorders, especially the pituitary pars intermedia dysfunction (PPID) in older animals. Morphologic exams of the laminar tissue of the hoof were performed in two horses with suspected PPID, with no clinical signs of laminitis. Changes compatible with laminitis of endocrine origin were observed, such as rounding of the nuclei of the basal cells, thinning and stretching of the secondary epidermal laminae and tissue proliferation. PPID horses with no clinical signs of laminitis may be affected by lesions of the laminar tissue of the hoof that compromise the integrity of the dermal-epidermal junction and may develop clinical symptoms of the disease. It has been suggested that the development stage...

Expression of matrix metalloproteases-2 and -9 in horse hoof laminae after intestinal obstruction, with or without Hydrocortisone treatment
Provedor de dados: Ciência Rural

Twenty horses were used in the experiment, for composed control group, (Cg) instrumented group, (Ig;without intestinal obstruction), treated group (Tg;submitted to intestinal obstruction and hydrocortisone treatment) and non-treated group (Ntg;submitted to intestinal obstruction without treatment). Immunohistochemistry and zymography techniques were used for researches on MMPs 2 and 9 in horse hoof laminae. There was an increase in the expression of MMP-2 in animals of Tg and Ntg. MMP-9 increased on animals from groups Ntg and Ig, however there was no rise of this MMP on the Tg when compared to the other groups in the immunohistochemistry analysis. Based on the results, it was observed that the intestinal injury caused by enterotomy and intestinal...

Effects of two different deep digital flexor tenotomy techniques on distal articular angles of equine cadaver forelimbs
Provedor de dados: Ciência Rural
Autores: Dearo,Antonio Cezar de Oliveira; Rosa,Vitor Bruno Bianconi; Reichmann,Peter; Oliveira,Milton Luis Ribeiro de.
Deep digital flexor (DDF) tenotomy is a technique employed for years to treat selected disorders of the musculoskeletal system in horses. Although two different surgical approaches (i.e. mid-metacarpal and pastern) have been described for performing the procedure, in vitro quantitative data regarding the modifications induced by either technique on the distal articular angles is lacking. Therefore, the purpose of the study reported here was to investigate the viability of a proposed biomechanical system of induced-traction used to compare the two DDF tenotomy techniques by measuring the distal articular angles of equine cadaver forelimbs. Ten pairs of forelimbs were collected and mounted to a biomechanical system developed to apply traction at the toe...
