ic resonance imaging(MRI) create strong magnetic fields within their immediate vicinity. This has generated some concerns over the effects that these fields may have on the outside environment and in particular on living organisms. 50/60Hz magnetic fields are of special concern because living organisms are exposed to them on a continuing basis.We investigate the influence of a strong 60Hz AC magnetic field of 1.2T on organisms. The high AC magnetic field is generated by using a multilayer eddy-current type AC magnetic generator developed in our laboratory. In this paper, in vitro experiments were performed with biochemical reactions, enzyme and restriction endonuclese activities.As a result, the magnetic field inhibited catalase activity slightly only in biochemical reactions. Other reactions such as β-galactosidase activity and restriction endonuclese activity were not influenced at all. The results suggest that high 60Hz AC magnetic fields may influence biological functions in some organisms.

概要:
Recent advances in high technological equipments such as MRI equipments and superconducting devices have given rise to a new environment where we are exposed to high ac magnetic fields. The influences of ac magnetic fields on

human functions, however, have not yet been fully examined, hence it becomes important to establish the safty level for human body of high ac magnetic field. On this study, we have investigated the influences of ac magnetic fields on the development and behavior of the nematode, Caenorhabditis elegans, as one of the fundamental biological experiments. And we use the multilayer eddy-current type high ac magnetic field generator as a magnetic field source. As the experiment, the nematode has been exposed to high ac magnetic field about 1.2T at 60Hz during 10 minuites every 3 hours from hatching to the start of egg laying. As a result, we have observed that a high ac magnetic field causes the decrease of 9% in brood size and the delay in the start of egg laying. Hence we have confirmed the delay of growth. Moreover, the abnormal behaviors such as disruptive reversals and backward movement were also observed. The exposed nematode of 49 percent shows these abnormal behaviors. These results suggest that high ac magnetic field may influence the nurves system and the musculer system of the nematode.
