Evoked potentials were produced by anodal stimulation over the motor cortex in six dogs. Potentials were recovered from the cranial thoracic and caudal lumbar portions of the spinal cord, and the radial and sciatic nerves. Evoked potential averages were recorded every 1.5 minutes during 40 minutes of aortic occlusion and during 40 minutes of reperfusion.(More)
Eleven dogs with naturally occurring oral squamous cell carcinomas were treated with photodynamic therapy (PDT) using Photochlor (HPPH) as the photosensitizer. The largest length of the tumours measured in a two-dimensional plane ranged from 0.9 to 6.8 cm. Seven of the tumours invaded underlying bone as determined by radiograph appearance. Photochlor was(More)
The percentages of change in cross-sectional area and dorsoventral height of the rima glottidis were measured after seven types of laryngoplasty in 30 postmortem canine specimens. The mean increases in area after each procedure were, in decreasing order, bilateral cricoarytenoid disarticulation with interarytenoid sesamoid band transection before placement(More)
OBJECTIVE To determine whether anesthesia of the infraorbital and inferior alveolar nerves abolishes reflex-evoked muscle action potentials (REMP) during tooth-pulp stimulation in halothane-anesthetized cats. ANIMALS 8 healthy adult cats. PROCEDURE In halothane-anesthetized cats, an anodal electrode was attached to the tooth to be stimulated and a(More)
Evoked potentials were induced by transcranial stimulation and recovered from the spinal cord, and the radial and sciatic nerves in six dogs. Stimulation was accomplished with an anode placed on the skin over the area of the motor cortex. Evoked potentials were recovered from the thoracic and lumbar spinal cord by electrodes placed transcutaneously in the(More)
