Mobile phones communicate with base stations using 900 MHz microwaves. The current study was aimed to survey the effects of long-term 900 MHz microwave exposure of mice on experimentally induced cutaneous candidiasis. Forty inbred, male, BALB/c mice were randomly divided into four groups. Cutaneous lesions with were experimentally induced on the lateral-back skin of the 20 mice. One group of the diseased mice were exposed (6 h per day and 7 d per week) to 900 MHz microwave radiation, while the other groups were not exposed. Two unexposed control groups were also included. The skin lesions were regularly monitored and the live candida cell density was enumerated using the colony-forming unit (CFU) assay. The process was repeated after a one week resting interval. One week later, all mice were challenged through intra tail veins using LD dose of . Mortality of the mice was recorded and the candida load of the kidney homogenates from died animals was counted. 900 MHz microwave exposed mice had 1.5 day and 3.7 day delays on wound healing in stages two. Live Candida inoculated Wave exposed (LCW) mice also showed higher yeast loads in skin lesions at days 5, 7 and 9 post inoculation. Survival analysis of live candida challenged mice showed the radiation exposed group is prone to death induced by systemic infection and candida enumeration from the kidney homogenates showed radiation exposed animals have had significantly higher yeast load in the tissue. In collection, long-term 900 MHz radiation exposure of mice led to longevity of skin wounds and susceptibility of the animals to systemic challenge and higher incidences of microorganisms in internal tissues.
移动电话使用900兆赫微波与基站进行通信。当前的研究旨在调查长期900兆赫微波照射小鼠对实验性诱导的皮肤念珠菌病的影响。40只近交系雄性BALB/c小鼠被随机分为四组。在20只小鼠的侧背部皮肤实验性诱导出皮肤损伤。一组患病小鼠每天暴露(每天6小时,每周7天)于900兆赫微波辐射下,而其他组不暴露。还包括两个未暴露的对照组。定期监测皮肤损伤情况,并使用菌落形成单位(CFU)测定法计算活念珠菌细胞密度。在休息一周后重复该过程。一周后,所有小鼠通过尾静脉注射致死剂量的[此处原文缺失具体内容]进行攻击。记录小鼠的死亡率,并计算死亡动物肾脏匀浆中的念珠菌载量。暴露于900兆赫微波的小鼠在第二阶段伤口愈合延迟了1.5天和3.7天。接种活念珠菌的微波暴露(LCW)小鼠在接种后第5、7和9天皮肤损伤中的酵母载量也更高。对活念珠菌攻击小鼠的生存分析表明,辐射暴露组更容易因全身感染而死亡,并且从肾脏匀浆中进行的念珠菌计数显示,辐射暴露动物组织中的酵母载量明显更高。总的来说,长期900兆赫辐射暴露的小鼠导致皮肤伤口愈合时间延长,动物对全身攻击的易感性增加,以及内部组织中微生物的发生率更高。
