RESUMEN
Selected serum enzymes, cholesterol, triglycerides, glucose, uric acid, protein, albumin, bilirubin, BUN, hematology, and electrocardiograms (EKG) were obtained from adult male cynomolgus (Macaca fascicularis) and adult male stumptailed (Macaca arctoides) macaques. Serum alkaline phosphatase, uric acid, albumin, bilirubin, mean corpuscular hemoglobin (MCH), mean corpuscular volume (MCV) and monocytes were significantly lower in the cynomogus monkeys. This relationship was reversed for serum levels of triglycerides, phosphorus, red blood cell counts and lymphocytes. EKG analysis revealed significantly increased PR interval and QRS wave duration in the cynomolgus species. However, there were no differences in heart rate. Right axis deviation was common in both species.
