Magnesium is the major intracellular divalent cation and is involved in many physiological processes. Magnesium deficiency may lead to osteoporosis. However, magnesium supplementation may promote bone growth and prevent osteoporosis. This paper reviews the progress on the mechanism of magnesium-stimulated bone growth and bone metabolism.

Objective: To study the effects of Tengcha flavonoids (TCF) on scavenging oxygen free radicals and inhibiting lipid-peroxidation., Methods: The effects of TCF on scavenging superoxide anion radical induced by xanthine-xanthine oxidase, inhibiting lipid-peroxidation of heart, liver, brain tissue homogenate and mitochondria induced by Fe2+ -VitC, Fe2+ -H2O2, Fe-Cys were discussed by TBA spectrometric method., Results: TCF could significantly inhibit the superoxide anion radical, IC50 is 14.7 mg/L, and the lipid peroxidation of liver homogenate and mitochondria induced by auto-oxidation and induced-oxidation. The inhibition exhibited concentration-dependent manner., Conclusion: It indicated that TCF could scavenge oxygen free radicals and was capable of prophylacticly antagonizing against the oxidative injury by superoxide anion.
