[Effects of distorted geomagnetic field on the functioning of systems supporting rat's bone matrix adaptation and
Abstract:
Physiological responses of rats to daily 30-minute exposure to distorted geomagnetic field (DGMF) over 3 and 7 days and their reaction to open field following the exposure were studied. Increases in blood 11-oxycorticosteroids (11-OCS) were observed equally after 3- and 7-day DGMF exposure, whereas adrenal 11-OCS was found increased only on DGMF day-3; neither adrenaline in the adrenals nor glycogen in the liver were affected. On DGMF day-7, activation of bone matrix demineralization manifested itself by increased phosphorus and decreased calcium in blood, and activation of acidic phosphatase in serum. Rats reacted to open field by increases in blood and hepatic 11-OCS, reduction in adrenaline in the adrenals and glycogen in the liver, increase in serum free oxyproline and acidic phosphatase activation, and inhibition of alkaline phosphatase. Seven-day DGMF heightened or aggravated the reaction to open field.

Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
