[Changes in clinical and immunological laboratory parameters of healthy adults after exposure to a one-hour 40 degree C-whole-body hyperthermia (author's transl)].

There are no signs of organ lesions in healthy subjects exposed to an 1-hour 40 degree C whole-body hyperthermia, induced by radiofrequency or infrared light. As to the immunological in vitro parameters, only a slight decrease of the relative T-cell count is seen, T-cell functions however being normal. A leukocytosis appearing during infrared-induced hyperthermia is probably related to the erythema caused by skin heating. About possible indications and clinical values of this treatment, nothing can however be said so far.
