Electrocardiography-gated dynamic magnetic resonance imaging (MRI) methodology was developed for the in vivo examination of sheep heart characteristics. By combining noninvasive determination of skeletal muscle mass, we studied the relationship between total body skeletal muscle content and heart performance. Measurements were carried out on male Merino lambs using 1.5 T field strength equipment. Average left ventricular volumes were determined and stroke volume was estimated during image postprocessing. Ejection fraction was calculated (73 ± 1.8%) and the cardiac output (CO) value was estimated (2.75 ± 0.16 L/min). After measuring left ventricular wall thickness, contraction values were determined at the septum (62%), …

The aim of this study was to evaluate arginase activity and aspartate aminotransferase (AST) levels in the tissues of the cardiac and skeletal muscle and liver of lambs with white muscle disease (WMD). The cardiac and skeletal muscle and liver tissues were obtained from 8 lambs with WMD and 9 apparently healthy lambs. The diagnosis of WMD was made with the detection of hyaline degeneration upon histopathological examination. A significant increase in arginase activity in the cardiac and skeletal muscle and liver tissues and a significant decrease in AST levels in the cardiac muscle were detected in the WMD group …
