OBJECTIVE To compare obese horses with insulin resistance (IR) with nonobese horses and determine whether blood resting glucose, insulin, leptin, and lipid concentrations differed between groups and were correlated with combined glucose-insulin test (CGIT) results. ANIMALS 7 obese adult horses with IR (OB-IR group) and 5 nonobese mares. PROCEDURES(More)
The concept of an equine metabolic syndrome (EMS) was first proposed in 2002. This concept has developed over time, and EMS was recently described in a consensus statement released by the American College of Veterinary Internal Medicine. In human medicine, metabolic syndrome (MetS) refers to a set of risk factors that predict the risk of cardiovascular(More)
The clinical features of hyaline membrane disease have been reviewed recently (1, 2). When the disease is fatal the lungs at autopsy are usually grossly atelectatic, suggesting the appearance of liver. Microscopically, this atelectasis is seen to be patchy and widespread; scattered through the lungs are dilated terminal bronchioles and alveolar ducts that(More)
OBJECTIVE To characterize the physiologic response to i.v. bolus injection of glucose and insulin for development of a combined glucose-insulin test (CGIT) in horses. ANIMALS 6 healthy mares and 1 mare each with pituitary adenoma and urolithiasis. PROCEDURE Horses were given a CGIT (glucose, 150 mg/kg; insulin, 0.1 U/kg); results were compared with a(More)
BACKGROUND A combined dexamethasone (DEX) suppression/thyrotropin-releasing hormone (TRH) test (DEX/TRH test) has been developed to evaluate horses for presence of a pars intermedia pituitary adenoma (PIPA), but to the authors' knowledge, the accuracy of this test has not been previously determined. HYPOTHESIS The sensitivity and specificity of the(More)
