A study was made of the effects of cortisol on hypothalamic potentials evoked in the rat by sensory and limbic stimulation. The hormone was found to increase the amplitude and to reduce the latency of the evoked potentials. It also enhanced the early facilitation in the recovery cycle of the response to septal stimulation, but prolonged the inhibitory phase(More)
Transcutaneous electrical nerve stimulation (TENS) is applied for the relief of various types of pain, including rheumatoid arthritis and osteoarthritis. This study evaluated the influence of TENS on intraarticular (IA) temperature and pressure and synovial tissue of inflamed rabbit joints. Four hours after induction of acute bilateral hind joint arthritis(More)
To determine the effect of transcutaneous electrical stimulation on the rabbit joint, we studied skin and intraarticular temperatures and pressure both before and following the stimulation in nine rabbits. An elevation in skin temperature by a mean of 0.6 degrees C (p less than 0.05) and increase in intraarticular temperature by a mean of 0.8 degrees C (p(More)
The effect of morphine and oxotremorine, a centrally acting cholinergic agonist on the respiratory rate and arterial blood gases, was studied in rabbits given saline, increasing doses of morphine (5 mg/kg, 2 days; 10 mg/kg, 2 days; and 20 mg/kg, 3 days) injected at 12-hr intervals for 1 week. Care was taken to ensure that the chronically morphine-treated(More)
