Autor: Mayumi Obo, Shiro Konishi, Satoshi Kitamura, Yoshihisa Otaka
Publikováno v: Bioelectromagnetics. 23:306-314
Calcium influxes through the membrane of PC-12D cells were measured under exposure to DC biased AC magnetic fields in resonant conditions of the ion cyclotron and the ion parametric resonance hypotheses and compared with influxes in cells without exp

Publikováno v: Bioelectromagnetics. 23:206-213
Some epidemiological studies suggest association of childhood cancer with occupational exposure of the parents to magnetic fields. To test this relationship, 50 each of C57BL/6J female and C3H/HeJ male mice were exposed for 2 and 9 weeks, respectivel

Multigeneration exposure test ofDrosophila melanogaster to ELF magnetic fields
Autor: Masahiro Ogawa, Takehiko Kikuchi, Masako Furuta, Yoshihisa Otaka
Publikováno v: Bioelectromagnetics. 19:335-340
Mutations, other than dominant lethals, were accumulated on wild type second chromosomes (+) of Drosophila melanogaster during exposure to 50 Hz sinusoidal alternating magnetic fields of 0.5 or 5 mT (rms) for 40 generations by the Curly/Plum(Cy/Pm) a

Sex-linked recessive lethal test ofDrosophila melanogaster after exposure to 50-Hz magnetic fields
Autor: Yoshihisa Otaka, Satoshi Kitamura, Masako Furuta, Akemi Shinohara
Publikováno v: Bioelectromagnetics. 13:67-74
To determine whether a 50-Hz magnetic field will induce mutations, a sex-linked recessive lethal test of Drosophila melanogaster was performed. Adult flies were exposed at an rms flux density of 500 mu T or 5 mT to the homogeneous field of a Helmholt

Publikováno v: Bioelectromagnetics. 24(1)
Several epidemiologic studies have suggested an association between exposure to extremely low frequency (ELF) magnetic fields (MFs) and cancer in adults and children. A possible target of MFs is the immune system. The effects of the exposure to ELF M

Publikováno v: Electricity and Magnetism in Biology and Medicine ISBN: 9781461372080
One of the assertion of epidemiological studies was correlation between electromagnetic field exposure and childhood cancer. Some epidemiological studies (Savitz et al., 1990) dealt with parental occupations relating to filial incidence of cancer. We

Publikováno v: Electricity and Magnetism in Biology and Medicine ISBN: 9781461372080
Epidemiological studies suggested a correlation between electromagnetic field exposure and cancer. We performed previously a series of animal exposure tests, according to the standard routine for chemical investigation. The series included two NTO st
