This paper reviews the effects of electromagnetic fields, from DC to microwaves, on biological systems. Electrical properties of biological substances are briefly described. At DC, strong magnetic fields and steady DC electric fields are reported to produce several effects. At low frequencies, interest of many researchers is centered around stimulation, involuntary movements and shock hazards. produced by currents flowing through the body. Results of several experimental studies are cited. With shifts to higher frequencies, there seem to arise several points which need further clarification. At ultra-high and microwave frequencies, situations are quite different. Most of the effects produced are usually considered attributable to heat developed by electromagnetic energy dissipation, although several papers point out non-thermal effects. Calculations by electromagnetic theory and some experimental results are described. It is emphasized that several points need urgent solution.

To simulate blood pressure measurement done by medical doctors, a new type stethoscope, which is a commercialy available stethoscope equipped with an eddy-current displacement sensor and a microphone, is developed. Using this stethoscope and impedance plethysmograph, pulse wave-forms and sounds distal to the cuff and volume change of the artery under the cuff were measured in various experiments. In some experiments, common blood pressure measuring process is adopted and, in other experiments, cuff-pressure is kept constant. From the experimental results, the following facts are known. 1) Blood flow rate coming from upstream in the collapsed artery under the cuff is not affected by arterial pressure distal to the cuff. 2) Always the same sounds are produced when experimental conditions are kept constant. 3) When sounds are heard there exist always steep wave fronts. From these facts, the true mechanism of Korotkoff sound generation is known to be hydrolic-jump formation at the wave front during pressure wave propagation through collapsed artery segment under the cuff.

Gender identity disorder (GID) is a condition in which sex differs from gender identity. The basic methodology used to diagnose such a disorder involves examination by more than one psychiatrist. It is necessary to develop objective, quantitative criteria for diagnostics in order to improve the credibility of diagnosis, and to aid in decisions as to whether a patient is eligible for sex reassignment surgery. It has long been believed that there are sex-related differences in the shape and size of the corpus callosum (which interconnects the two cerebral hemispheres), and that these differences could form the basis of an objective, quantitative diagnostic technique. Unfortunately, there are, as yet, no established methods. In this study, we used MRI to investigate sex-related differences in the corpus callosum. We described the callosal figures at the midsagittal plane, using Fourier descriptors and central moments to represent the shape. We found that females have stooping corpus callosum relative to males, at a significance level of 10-14. This suggests that sex-related differences in the corpus callosum may consist of differences in the callosal configurations in the cranium, rather than the shape and size of the corpus callosum. Furthermore, using statistical tests (a likelihood ratio test, Kruskal-Wallis test and Mann-Whitney test), we found that most of the GID subjects in our study (MTF, 4; FTM, 11) have a principal orientation of the corpus callosum that is closer to female than male in sex. This means that the callosal principal orientation may qualify as an objective, quantitative criterion for MTF diagnosis.

Data communication, referred to as Computer Communication or Remote Data Processing in Western countries, has enabled acquision of numerous data over a wide range and to send back or switch messages to and fro, through linking of the on-line real-time computer data processing and the simultaneity and extensiveness of telecommunications. In the medical fields, three applicable areas for data communication are conceivable as in the general industrial fields.The first area is the centralized storing of medical information for responding to inquiries from remote terminals. The Swedish public health system is an example of this area. It covers the whole population in Sweden under the countrywide network of medical care and keeps the medical records in the personal files of the mass-storage center, based on the central population register.The second is the data communication system to analyse automatically the biomedical signals and raw data from medical examinations. The Medical System Development Laboratory (MSDL), U. S. Public Health Service (USPHS) has been developing the automatic analysis system of the electrocardiograph and the forced expiratory spirogram connecting computers, telephone lines and remote terminals.The third application is the shared data processing system in which the participating users share a computer system and its resources for economical reason. The Minnesota Blue Cross's shared data processing system is an example of this kind.The expected future application of data communication is the remote diagnostic system with the specialist physicians in the center; it will be based on the development of the computer and communication technologies and progress made in technical methods of combining telephone networks with medical instruments.The availability and extensiveness of data communication in the medical fields are herein presented.
