Effect of Pulsed Electromagnetic Field on Bone Formation and Lipid Metabolism of Glucocorticoid-Induced Osteoporosis Rats through Canonical Wnt Signaling Pathway

Figure 1

The serum concentrations of alkaline phosphatase (ALP) and tartrate resistant acid phosphatase (TRAP) in each group before and after treatment ((a) A, B). The results of serum biochemical analysis in each group before and after treatment include serum calcium (Ca), phosphorus (P), triglyceride (TG), total cholesterol (TCHO), high density lipoprotein cholesterol (HDL), and low density lipoprotein cholesterol (LDL) ((a) C, D). The L4 vertebral bodies were stained with Safranin-O/Fast green: ((b) A) control group, ((b) B) GIOP group, ((b) C) calcium group, and ((b) D) PEMF group; bone tissue was stained in grayish-green or blue; cartilage tissue was stained in red. The L4 vertebral bodies also were stained with HE staining solution: ((b) E) control group, ((b) F) GIOP group, ((b) G) calcium group, and ((b) H) PEMF group. The rate of OPG to RANKL mRNA and protein expressions in each group after treatment ((c) A, B). Compared with the control group, ; compared with the GIOP group, ; compared with calcium group, .
