We investigated whether stimuli consisting of beautiful and ugly colours as judged by human subjects elicit different autonomic response patterns. The autonomic functions recorded were heart rate (HR) respiration rate, skin conductance, number of GSFs (nGSR) and also eye movements, as an index of somatic activity. In order to obtain strong responses, i.e. to avoid inhibition of 'natural' responses by anxiety due to the laboratory setting, we made use of post-hypnotic suggestions regarding the nature of the stimuli the subjects were to expect.
The effects of hypnosis, acupuncture and analgesic drugs on the subjective experience of pain and on objective neurophysiological parameters were investigated. Pain was produced by brief electric stimuli on the wrist. Pain challengers were: hypnosis (induced by two different video tapes), acupuncture (at specific and unspecific loci, with and without electrical stimulation of the needles), morphine and ketamine. Evaluation of clinical parameters included the subjective experience of pain intensity, blood pressure, puls, temperature, psychosomatic symptoms and side effects.
Pharmacological effects of ifenprodil (IP), 4-benzyl-alpha-(p-hydroxyphenyl)-beta-methyl-1-piperidineethanol-L-(+)-tartrate monohydrate (Funai Pharmaceutical), a potential vasodilator, were studied in the dog, rabbit, guinea-pig and mouse. 1) Intravenous administration of IP (0.1 approximately 1 mg/kg) exhibited a continuous fall in blood pressure, an increase in heart rate and an increase in cardiac contractile force in the dog. The depressor and chronotropic effects of IP appeared likewise in the pithed dog, and the depressor responses were slightly more evident in the rabbit.
Eighty-five patients ranging from 12 h to 7 years of age were included in this study. In the first group 35 cases received ketamine, gallamine and oxygen for surgery on the great vessels. Ketamine provided satisfactory analgesia and amnesia. Heart rate did not change significantly. Gallamine gave additional safety in the prevention of bradycardia. One hundred per cent oxygen increased oxygen saturation and made more oxygen available for the tissues. The combination secured favorable conditions even in cases of sevre right to left shunt.
