摘要:

Two‐dimensional echocardiography was performed on 18 unanesthetized, normal dogs (4.5 to 30 kg). Measurements of wall thickness, intracavitary dimensions, and cross‐sectional area of the left atrium, left ventricle, and aorta were made. Satisfactory data were obtained from 17 dogs, and were used to determine normal values. Normal data were tested for significant correlation to body weight (kg) by linear regression. Repeatability was studied in six dogs examined, on three separate occasions, during a 5‐day period. Differences between values obtained on different days were evaluated by analysis of variance.Satisfactory qualitative echocardiograms were repeatedly obtained by using consistent sites of transducer placement and by identifying internal cardiac structures. These tomographic planes were highly reproducible, with only ventricular length, and some views of the ventricular septum, showing statistically significant (P<0.05) differences. Almost all linear and area measurements were significantly correlated to body size, while most indices of left ventricular function were independent of body weight. Dimensions obtained from the left and right parasternal position were nearly identical. Cross‐sectional echocardiography allows repeatable assessment of cardiac anatomy, and it should prove useful for identification and quantitation of heart disease in

摘要:

A cat was presented with a non‐weight‐bearing lameness of the left thoracic limb, painful joints and lymphadenopathy. Marked bilateral osteolysis of the distal radial and ulnar metaphyses was detected radiographically. A post mortem diagnosis of disseminated histoplasmosis and feline lymphosarcoma was m

摘要:

Standing myelography was conducted in six neurologically normal adult horses. Myelograms were performed without general anesthesia or tranquilization. Four horses were premedicated orally with 2.2 milligrams/kilogram (mg/kg) of phenobarbital 16 hours and 4 hours prior to myelography to raise their seizure threshold. One‐hundred milliters (ml) of cerebral spinal fluid (CSF) was withdrawn from the lumbosacral space prior to injection. Approximately 100 ml of technical grade metrizamide*was injected into the subarachnoid space via a lumbosacral tap. After injection the horse's head was lowered for approximately 10 minutes to facilitate cranial movement of the metrizamide. Lateral cervical radiographs were taken in a standing position. Filling of the subarachnoid space in the cranial cervical region was good to excellent in five horses. In one horse there was poor definition of the cranial cervical region. There was good to excellent filling of the subaranoid space in the caudal cervical region in all six horses. Reactions to metrizamide injection varied. The most severe reaction was generalized seizur

摘要:

Angular deformities of 25 or 37 degrees valgus were created by transverse wedge osteotomies in the diaphysis of the radius in 3‐month‐old Cocker Spaniels. Spontaneous correction was judged from radiographs until skeletal maturity. The magnitude of correction was estimated, using the opposite normal leg as a control. Asymmetrical physeal growth corrected the induced angulation between the proximal and distal radial joint plane surfaces (joint plane angle). The average correction of the joint plane angle was 80% in the 25 degree group, and 72% in the 37 degree group. Bone remodeling of the radial shaft corrected the induced diaphyseal angulation by 50% in both groups during the st
