Although laser endarterectomy has recently been suggested as useful in the treatment of arteriosclerotic obstructions, the "in vivo" clotting effects have not been well delineated. In this study, the common carotid and femoral arteries of ten mongrel dogs were exposed, and alternating 1 cm segments of each artery were treated with surgical endarterectomy and low-powered CO2 laser endarterectomy...

NAHMOD, VICTOR E., AND ALFREDO LANARI. AboZition of autoregulation of renal blood J-low by acetylcholine. Am. J. Physiol. 207(r): 123-127. 1964.~-In order to study the mechanism of autoregulation of renal blood flow, 36 mongrel dogs were connected in parabiosis according ,to the Brull method. The following determinations were made : a) flow/pressure curves in innervated and denervated kidneys a...

Brain perfusion computed tomography (CT) scanning was performed in a mongrel dog and a golden retriever that were diagnosed with third ventricular tumor and olfactory bulb tumor, respectively, by contrast-enhanced CT. The tumors were pathologically diagnosed as ependymoma and meningioma, respectively. Perfusion CT results revealed that the ependymoma in this study had a lower blood flow, higher...

OBJECTIVES To establish an animal model of proximal descending thoracic aortic aneurysm for the study of branched stent grafts. MATERIALS AND METHODS Eleven mongrel dogs underwent the surgical procedure during which an autologous pericardial patch was sewn onto a longitudinal incision in the anterolateral wall of the thoracic aorta near the left subclavian artery to create an artificial thora...

The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the ...

The purpose of this study was to evaluate epinephrine-aminophylline-induced arrhythmias during halothane anaesthesia after induction with thiopentone or midazolam. Ten mongrel dogs were studied during 1 MAC halothane and 50% N2O:O2 anaesthesia while maintaining constant acid-base status. The minimal arrhythmogenic infusion rate of epinephrine (MAIRE) and the corresponding plasma concentration o...

A 16-year-old castrated male mongrel cat presented with swelling under the left pinna and a 3 -month history of voice change. Laryngeal endoscopy revealed circumferential oedema around the arytenoid cartilages and hypersecretion of saliva. Histopathological examination of the mass around the left ear canal was considered the primary lesion that originated from cutaneous apocrine adenocarcinoma ...

The function of the posterior cricoarytenoid (PCA) muscle in phonation has not been well documented. To date, several electromyographic studies have suggested that the PCA muscle is not simply an abductor of the vocal folds, but also functions in phonation. This study used an in vivo canine laryngeal model to study the function of the PCA muscle. Subglottic pressure and electroglottographic, ph...

Cr' labeled red cells mid I huniiin serum iilbumin were injected intrnvenously into S mongrel dogs. After 1 hour kidneys were removed and frozen rapidly with dry ice. Sections of outer cortex, inner cortex, outer medulla, inner niedulhi, outer pnpilln nnd inner papilla were removed and analyzed for Cr and I radioactivity. Tissue mdioactivity was compared with that of arterial blond and concentr...

Cox, ROBERT I-3. InfIuence of chloralose anesthesia on cardiovascular function in trained dogs. Am. J. Physiol. 223(3): 660-667. 1972.The acute hemodynamic responses to chloralose anesthesia were determined in nine trained, chronically instrumented mongrel dogs. They were instrumented for the measurement of ascending aorta pressure and blood flow, and left ventricular and central venous pressur...
