Recovery Effects of a 180 mT Static Magnetic Field on Bone Mineral Density of Osteoporotic Lumbar Vertebrae in Ovariectomized Rats

Figure 4

The E₂ concentrations in the rat blood serum 6 weeks after ovariectomy or nonovariectomy. SMF: ovariectomized and implanted with a disc magnet; Sham: ovariectomized and implanted with a nonmagnetized disc; OVX: ovariectomized alone; CTL: intact (nonoperated) cage control. 𝑛=10 in each group. ^∗𝑃<.05 versus CTL. no. of rats under the detection limit (<5 pg/mL): SMF, 𝑛=7; Sham, 𝑛=7; OVX, 𝑛=3; CTL, 𝑛=2. These E₂ levels were shown as “0” at the E₂ concentration.
