Effects of ginsenoside Rg3 on bone loss, bone mineral density and osteoclast number in glucocorticoid-induced osteoporosis rats, and the likely michanism of action
Get PDFPurpose: To investigate the effect of ginsenoside Rg3 on bone loss, bone mineral density (BMD) and osteoclast number in glucocorticoid-induced osteoporosis (GIOP) rats, and the mechanism of action involved.Methods: Sixty female Wistar rats were assigned to control, model group, ginsenoside Rg3, and alendronate sodium groups, comprised of 15 rats per group. The osteoporosis rat model was established via intramuscular injection of dexamethasone. Changes in bone mineral content (BMC), BMD trabecular thickness and area, osteoblasts and osteoclasts in femurs and lumbar vertebrae were measured after 3 months of treatment.Results: There were significantly higher BMC and BMD levels in ginsenoside Rg3 group than in alendronate rats (p < 0.05). The thickness and trabecular area in femur and lumbar vertebrae in the ginsenoside Rg3 group were significantly higher than those in the model group (p < 0.05), but were comparable with those in the alendronate sodium group (p > 0.05). There were marked increases in osteoblasts, and marked decreases in osteoclasts in the ginsenoside Rg3 group, alendronate sodium and control rats, relative to model rats (p < 0.05).Conclusion: Ginsenoside Rg3 arrests bone loss, and enhances bone density, trabecular thickness and area, bone microstructure, osteoblast activity and population of osteoclasts number in glucocorticoidinduced osteoporotic rats. This provides a new research direction for the clinical treatment ofosteoporosis.

No full textObjectiveː To investigate clinical and radiological results of alternating levels compared with all levels mini-plate fixation in open door cervical laminoplasty for treatment of degenerative cervical myelopathy. METHODSː From January 2011 to April 2014, 64 patients sustained degenerative cervical myelopathy, who underwent cervical laminoplasty with alternating levels (31 patients in group A) or all levels plate fixation (33 patients in group B) were included in this retrospectively study. Clinical and radiological results were calculated. RESULTSːThe mean cost for group B was higher than group A(P < 0.05). No statistical difference was found in the mean operation time, blood loss, axial symptoms，C5 palsy, improvement in JOA and NDI score between group A and B. Open angle in mini-plate fixed levels was significantly more than that in suture fixed levels(P < 0.05). No statistical difference was found in drift back of spinal cord, APD, Pavlov's ratio, CCI and ROM between mini-plate fixed levels and suture fixed levels.CONCLUSIONSː Open door laminoplasty at alternating levels mini-plate fixation is an economical surgical method and can obtain similar satisfactory clinical and radiological results compared to all levels mini-plate fixation.
