This study deals with the effects of post (12 or 18 months) whole body continuous (2 years) exposure of rabbits to 650 MHz electromagnetic fields (EMF) that are characteristic of those produced by broadcasting stations, on body weight and body mass, on the morphology of liver, spleen and brain, and on apoptosis rates and glycogen distribution in the liver. Two groups of rabbits were continuously exposed for 2 years to EMF of 650 MHz followed by 12 months (group 1) or 18 months (group 2) of post-exposure; a third group (group 3) was sham exposed. It was shown that the changes in apoptosis rates were conditional during the time of exposure, but not on a specific organ and that the whole body continuous exposure gave rise to modifications whose types and intensities were related to the time of post-exposure (12 or 18 months, respectively), the type of organ, and the individual animal. A number of effects were observed only in group 1, and not in group 2, which suggests some kind of adaptive response or of long-term recovery in the rabbits following continuous exposure to 650 MHz EMF.
本研究探讨了兔子在全身连续（2年）暴露于650兆赫电磁场（EMF）（这种电磁场是广播电台所产生的典型电磁场）12个月或18个月后，对其体重、体质量、肝脏、脾脏和大脑形态以及肝脏细胞凋亡率和糖原分布的影响。两组兔子连续2年暴露于650兆赫的电磁场，随后分别进行12个月（第1组）或18个月（第2组）的暴露后观察；第三组（第3组）为假暴露组。结果表明，细胞凋亡率的变化在暴露期间是有条件的，但并非针对特定器官，并且全身连续暴露会引起一些改变，其类型和强度与暴露后时间（分别为12个月或18个月）、器官类型以及个体动物有关。仅在第1组中观察到了一些效应，而第2组中未观察到，这表明兔子在连续暴露于650兆赫电磁场后出现了某种适应性反应或长期恢复。
