Abstract

A healthy 17-year-old girl presented with typical symptoms and physical features of Goldmann-Favre vitreoretinal degeneration. She had reduced visual acuity in both eyes and night blindness. Her parents were first cousins. Striking fundus features included typical maculopathy with a radiating stellate pattern surrounded by tiny vacuole-like pockets of retinoschisis throughout the posterior pole within the temporal vascular arcades. The fundus features were quite typical and permitted a firm diagnosis when combined with the other features of night blindness, gender, and electroretinogram (ERG) abnormalities.

Abstract

In this study, 12 dogs were anesthetized with sodium pentobarbital, and blood flows were determined using the radioactive microsphere technique. Ten dogs were first made acutely hypertensive by the infusion of norepinephrine and demonstrated preserved cerebral autoregulation. The administration of naloxone, 10 mg/kg i.v., in these animals produced a significant increase in cerebral blood flow and a proportional drop in cerebrovascular resistance with no change in the cerebral metabolic rate of oxygen or the electroencephalogram. Two additional spontaneously hypertensive dogs demonstrated a similar response to naloxone. These results suggest that high dose naloxone produces cerebrovasodilation either directly or through the inhibition of cerebral autoregulation.
