[Relationship of iron overload to bone mass density and bone turnover in postmenopausal women with fragility fractures of the hip].

Objective: To study relationships between serum ferritin and bone metabolism in patients with hip fragility fractures.

Methods: This cross-sectional study included 76 postmenopausal women with hip fracture from Feburary 2011 to June 2012. The mean age of the women was (73 ± 10) years (range, 55-93 years) and the mean duration of menstruation was (22 ± 10)years (range, 5-50 years).

Induction of adaptive response: pre-exposure of mice to 900 MHz radiofrequency fields reduces hematopoietic damage caused by subsequent exposure to ionising radiation.

Purpose: To investigate whether an adaptive response can be induced in mice which were pre-exposed to 900 MHz radiofrequency fields.

Materials And Methods: Adult male Kunming mice were exposed to 900 MHz radiofrequency fields (RF) at power intensities of 12, 120 and 1200 μW/cm(2) for 1 h/day for 14 days and then subjected to whole body gamma-irradiation. The results were compared with those in unexposed control animals and those exposed to gamma-irradiation alone (without pre-exposure to RF).

Effects of 900-MHz microwave radiation on gamma-ray-induced damage to mouse hematopoietic system.

Exposure of humans simultaneously to microwave and gamma-ray irradiation may be a commonly encountered phenomenon. In a previous study data showed that low-dose microwave radiation increased the survival rate of mice irradiated with 8Gy gamma-ray; however, the mechanisms underlying these findings remain unclear. Consequently, studies were undertaken to examine the effects of microwave exposure on hematopoietic system adversely altered by gamma-ray irradiation in mice.

[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.
