Verbalrep0rts of pain and suffering in ischemic pain produced by a tourniquet to the upper arm followed by exercise of the occluded hand were studied in 8 highly hypnotizable college under~aduates under conditions of normal wakefulness, hyp- nosis Without anesthesia, an4 hypnosis with suggested anesthesia.

Subjects were able to distinguish between felt sensory pain and the concomitant suffering in verbal reports on numerical scales, Suggestions of hypnotic anesthesia reduced both sensory pain and suffering(in °open' reports) about 90 ~ in the gro~p as a whole, and eliminated both completely for 3 sabjects.

After 'zarning to escape painful electrical stimulation oI one leg, Cebus albi- fi'ons mot~keys were presented with a random schedule of 5 intensities, and they con- sistently responded with minimal latencies to the higher inte~sities during control sessions Preceding different sets of experimental sessions, the ~ onkeys received mild e~ectrical stimulation between loci beJow the knees that were i: qended to correspond to acupancture points. Following the majority of these 'acup~nctu.re treatments' significant elevations of escape tatencies were observed a t the higlher stimNus i~nsi~ ties. The decreased0 reactivities to noxiot~s, stimuli were often dela?ted~n onset fol|ow- ing the end of acup,ancture treatments, and st~bstantial alterations of escape behavior were dete,:ted up to 70 h post-treat:mont. Regardless of the relevance of this finding to acupunct~re, it represents an unusually enduring alteration of pain sensitivity fo|low- ing stirr uiation of the body surface in a situation free frc,m suggestive influences.
