Studies of endocrine and affective functions in complex flight manoeuvres.

Endocrine and metabolic changes, as well as affective functions, were studied in eight healthy volunteers anticipating and executing a prearranged sequence of aerobatic flight. Control measurements were made at complete physical and mental rest. The following were determined: anxiety and hostility levels, blood glucose, cholesterol, triglyceride, plasma free fatty acids (FFA), serum thyroxine (T4), corticosteroids, prolactin, growth hormone, immunoreactive insulin and urinary excretion of VMA.

The present status of hypnosis.

In this brief survey of the medical uses of hypnosis the author attempts to clarify the various theories of hypnosis, indications for its use in medical practice, and applications in the treatment of psychosomatic disorders, psychiatric disorders and in miscellaneous cases. Brief descriptions of a variety of induction methods are given, and the potential hazards of hypnosis are explored. It is the author's impression that the practice of hypnosis has, through the years, been misunderstood and often unjustly discredited.
