Tytuł:: Influence of magnetic energy on protein contents in the fifth instar larvae of silkworm, Bombyx mori (L) (Race: PM x CSR2)

Opis:: The fifth instar larvae of multivoltine crossbreed race (PM x CSR2) of silkworm, Bombyx mori (L) were exposed to the magnetic energy of various strengths (1000, 2000, 3000 and 4000 Gauss magnetic field). The magnetization of fifth instar larvae was carried out on the first four days, for half an hour for each day before first feeding. Bioassay of total proteins was carried out on the fifth day of fifth instars. The attempt reveals influence of magnetization of Bombyx mori larvae on the total protein content level in the silk glands, fat bodies and haemolymph. The total protein content was increased with increase in the strength of magnetic field from 1000 to 4000 Gauss magnetic field. The larvae magnetized with 4000 Gauss magnetic field were found with sustained or decreased in total protein contents. Silk gland total proteins were increased from 5.901 to 17.481 percent. Total proteins of fat bodies were increased from 18 to 46.517 percent. And the total proteins of haemolymph were increased from 16.606 to 33.588 percent. Magnetization may have had influence on the increase in the levels of amino acids followed by accelerated rate of protein synthesis in the fifth instar larvae of silkworm, Bombyx mori (L) (Race: PM x CSR2). Magnetic energy should be utilized as efficiently as possible for the progression of growth of larval instars of silkworm, Bombyx mori (L).

Tytuł:: Menometrorrhagia in magnetic resonance imaging operators with copper intrauterine contraceptive devices (IUDS): A case report
Autorzy:: Gobba, Fabriziomaria
Bianchi, Nadia

Data publikacji:: 2012-03-01
Wydawca:: Instytut Medycyny Pracy im. prof. dra Jerzego Nofera w Łodzi
Tematy:: static magnetic fields

menometrorrhagia
Opis:: The paper describes the cases of 3 female health operators with implanted copper IUDs, developing menometrorrhagia some months after an increase of the working time in a Magnetic Resonance Imaging (MRI) Unit (1.5 T), that progressively disappeared when the previous organization, involving discontinuous work shifts at MRI, was re-established. No known factors possibly related to menometrorrhagia were evidenced in the 3 operators, supporting the hypothesis of a role of the exposure to the electromagnetic fields (EMF) induced by the MRI system in symptoms induction. The possible mechanism remains unsettled, but menometrorrhagia might be triggered by a phlogistic stimulus caused by EMF, possibly the lowfrequency currents induced in the wires of the IUD during the movements of the operator inside the static magnetic field generated by the MRI permanent magnet. Until now, the problem of possible interactions between copper IUDs and EMF induced by MRI has been considered in patients undergoing imaging, but the possible risk in MRI Units operators has been largely neglected. To our knowledge, the occurrence of menometrorrhagia is not routinely checked in health surveillance of MRI operators, so these symptoms can pass unnoticed, especially if they are transitory. Therefore, underreporting is rather possible. The cases described here support the need for further research on this topic, especially considering the progressive diffusion of more powerful MRI scanners (3 T and more), and of the interventional magnetic resonance imaging, both potentially involving higher EMF exposures, and a large number of MRI female operators, possibly using IUDs. The possibility that MRI operators with implanted metallic IUDs can be included in the group of “workers at particular risk” according to the EU Directive 2004/40/EC should be considered.

Tytuł:: Occupational Exposure to Power Frequency Fields in Some Electrical Transformation Stations in Romania

Data publikacji:: 2006

Opis:: The aim of this study is to investigate the levels of electric and magnetic power frequency fields at 8 electrical transformation stations in the North-East counties of Romania and to check their compliance with standards Spot measurements were carried out on both electric and magnetic fields under overhead conductors of 110-, 220- and 380-kV installations. The magnetic field levels were several orders of magnitude below the reference level for occupational exposure set by ICNIRP (International Commission on Non-Ionizing Radiation) or by Romanian regulations. In contrast, the electric field levels were about the same order of magnitude as the reference levels. In 2 electrical stations the reference level of 10 kV/m was exceeded at specific locations within the outdoor installations area. However, the additional reference level for short-time exposure included in Romanian regulations, 30 kV/m, was not exceeded.
