Prolonged magnesium deficiency causes osteoporosis in the rat.

Background: Peroral magnesium (Mg) administration, used as the only treatment in postmenopausal osteoporosis, has been shown to cause a significant increase of BD.

Objectives: To gauge the role of magnesium deficiency in the etiology of osteoporosis, we compared rats fed a Mg deficient diet daily with rats fed a Mg adequate diet over a period of one year.

Methods: Sprague-Dawley female rats (mean weight 110, SD 23 g) were divided into two groups of 8 and randomly assigned to an identical semisynthetic diet, containing either 2000 ppm (group A) or 200 ppm Mg (group B).

Experimentally induced prolonged magnesium deficiency causes osteoporosis in the rat.

Background: It has been shown that prolonged daily peroral magnesium (Mg) administration, as tabs of Mg(OH)(2), used as the only treatment in postmenopausal osteoporosis, causes a significant increase in BMD. Objective: In order to obtain definitive evidence of causality of magnesium deficiency in the etiology of osteoporosis, we spent 1 year examining rats given a daily Mg-deficient diet (200 ppm) and compared them with rats given a Mg-adequate diet (2000 ppm). Methods: Sixteen female Sprague-Dawley rats, mean weight 110 (S.

How significant is magnesium in thermoregulation?

Nine apparently healthy male subjects, mean age 22.8 yr, SD 4.1, free from disease, medication or addiction who gave informed consent, underwent acclimation process in a heat chamber; exposed during 2 h daily for 10 consecutive days to a temperature of 40 degrees C and 40% relative humidity while walking on a treadmill elevated by 3 degrees at a speed of 5 km/h (VO2 1.

Trabecular bone density in a two year controlled trial of peroral magnesium in osteoporosis.

Since magnesium regulates calcium transport, and magnesium replacement in magnesium-deficient postmenopausal patients resulted in unexpected improvement in documented osteoporosis, we investigated the effect of magnesium treatment on trabecular bone density in postmenopausal osteoporosis. Thirty-one postmenopausal patients (mean age +/- SD = 57.6 +/- 10.
