Multifunctional aesthesiometer "TELMEST".

A multifunctional device "TELMEST" has been developed for checking of actual temperature and for testing the perception threshold of electric current, mechanical vibration and temperature. The operational microprocessor system delivers appropriate stimuli by applicators to the finger tips or to other areas of skin, and the sensory responses of the proband are displayed on the screen of the monitor and stored in the memory. The estimation of tegumental temperature and perception thresholds of the above mentioned sensory stimuli supply valuable indices of sensory and vascular dysfunctions due to exposure to mechanical vibration transmitted to the hands. The results of such tests are exemplified.

Biological accounts emerging from some kinds of electromagnetic waves in the environment.

Industrial use of induction heaters generating electromagnetic energy of frequencies below 9 kHz makes an exposure of their operators to magnetic field H of high intensity and to electric field E of relatively low intensity. The operators of such heaters have suffered repeatedly from infections in the upper respiratory tract and in the skin of the forearm. The experimental exposure of rats to E or H fields of frequencies of 10 Hz, 50 Hz or 1-45 kHz induced changes in growth rate of exposed animals and weight changes in the pituitary-adrenal glands. These results support the suggestion about the involvement of the endocrine system in the biological reaction to incident electromagnetic fields of VLF and ELF.
