[The effect of ferric ion on the differentiation of osteoclast and bone resorption].

Objective: To explore the effects of ferric ion on the differentiation from both RAW264.7 and bone marrow macrophages to osteoclast in vitro and bone resorption in vivo.

Methods: In the presence of 50 ng/ml receptor activator of nuclear factor kappa-B ligand (RANKL), RAW264.

[Antagonistic effect of microwave on hematopoietic damage of mice induced by gamma-ray irradiation].

Objective: To investigate antagonistic effect of microwave on hematopoietic damage of mice induced by gamma-ray irradiation.

Methods: Male healthy Kunning mice were treated with low dose microwave radiation before exposure to (60)Co gamma-ray irradiation of 8.0 Gy.

[Radiation protection and possible mechanisms for low intensity microwave].

Objective: To investigate radiation protection and possible mechanisms of low intensity microwave on gamma-ray exposed mice.

Methods: 96 healthy Kunming mice were randomly divided into the following four groups: normal control, microwave (120 microW/cm(2), 900 MHz), gamma-ray irradiation (5 Gy), combined exposure of microwave and gamma-ray (120 microW/cm(2) + 5 Gy). The microwave group and combined group were exposed to 120 microW/cm(2) microwave firstly, 1 h/d, for 14 days.
