Static Magnetic Field Induced Hypovitaminosis D in Rat

[摘要] References(20)Cited-By(2)In the following study, we mainly investigate the effects of static magnetic field (SMF) (128 mT, 1 hr/day during 5 consecutive days) on 25-hydroxyvitamin D3 and calcium homeostasis. Wistar male rats, weighing 50–70 g, were randomly divided into four experimental groups: control, SMF-exposed rat, co-exposed rats (the last day and after exposure rats received a single dose of vitamin D per os) and supplemented with vitamin D group (without exposure to SMF). Exposure to SMF induced a decrease of plasmatic 25-hydroxyvitamin D3 level (PP>0.05). The same treatment failed also to alter body, relative liver and kidney weights. Interestingly, oral supplementation with vitamin D corrected hypovitaminosis D induced by SMF. Likewise, the same treatment failed to alter calcium homeostasis. More studies are needed to evaluate how SMF induces hypovitaminosis D.
