abstract：:Zinc has been shown to increase bone mass and promote bone cell proliferation and differentiation. We, therefore, hypothesized that zinc might be cytoprotective for bone cells during oxidative stress. The cells were divided into H(2)O(2), zinc and zinc+H(2)O(2) groups. In the present study, zinc was found to inhibit H...
