Pathological and Epidemiological Study on the Relationship between Electromagnetic Field Exposure and Lung Cancer.

14例肺癌病例和11例其他患者病例的长期磁性化已研究使用超导量子干扰设备（SQUID）。Natural remanent magnetization （NRM） of the specimen from lung cancer tissue （8.00 ± 13.11 × 10型D1-7型D1 emu） was two times stronger than that of the normal lung tissue （3.35 ± 3.35 × 10型D1-7型D1 emu）， and was significantly stronger than that of the controlls and the noise level of superconducting magnetometer。当比较来自其他患者的5种疾病的NRM时，肺部疾病具有最高的价值，由心脏、脊柱和肾脏跟随。肝脏组织的价值最低。所有五种类型的NRM都比控制更强，因为它包含了磁性材料的正常类型。生物磁铁是这些论文中可能的磁性材料。两个具有高磁性肺癌特异性的病例是专门研究其磁性性质的。替代费尔 ... More d demagnetization实验显示，它们的magnetization是一个稳定的单一载体组件，其中的指标是lung tissue may在the accumulation of the magnetic materials之后被magnetized。Wohlfarth的比率被确定为低于0.5的价值，并建议将磁性材料存在于集群分布中。元分析已被用来总结在电磁场（EMF）和成人leukemia之间的关系中的流行病学研究的结果。所有白血病的综合相对风险（RR=1.11），如急性淋巴细胞白血病（RR=1.38）、急性淋巴细胞白血病（RR=1.07）和慢性淋巴细胞白血病（RR=1.14）增加但不明显。到目前为止，这将使与电磁场和成人白血病的关系形成一个很大的一致性。需要使用披露评估的更有效的含义进行进一步的谨慎设计的案例控制和协同研究。Less（低）

Remanent magnetization of lung tissues of 14 cases of lung cancers and 11 cases of other patients was studied using Superconducting Quantum Interference Device (SQUID). Natural remanent magnetization (NRM) of the specimen from lung cancer tissue (8.00 ± 13.11 × 10ィイD1-7ィエD1 emu) was two times stronger than that of the normal lung tissue (3.35 ± 3.35 × 10ィイD1-7ィエD1 emu), and was significantly stronger than that of the controls and the noise level of superconducting magnetometer. When comparing the NRM of 5 kinds of tissues from other patients, lung tissues had the highest value, followed by heart, spleen and kidney. Liver tissue had the lowest value. NRM of all the 5 tissues were stronger than that of controls, indicating that the normal tissues contained the magnetic materials. The biological magnetite is the possible magnetic material in these tissues. Two cases of specimens with highly magnetized lung cancer tissue are especially studied on their magnetic properties. Alternating fiel … More d demagnetization experiment shows that the magnetization of them is a stable one vector component which indicates that the lung tissue may have been magnetized after the accumulation of the magnetic materials. Wohlfarth ratio of them is determined as the value less than 0.5, suggesting that the magnetic materials exist in the lung tissue as the cluster distribution.The meta-analysis was Used to summarize the results of epidemiological studies on the relationship between occupational exposure to an electromagnetic field (EMF) and the risk of adult leukemia. The combined relative risk of all leukemia (RR=1.11), as well as acute lymphocytic leukemia (RR=1.38), acute myeloid leukemia (RR=1.07) and chronic lymphocytic leukemia (RR=1.14) increased but not significantly. So far, it is difficult to make a consistent conclusion about the relationship of the occupational exposure to EMF and adult leukemia. Further carefully designed case-control and cohort studies using the more valid means of exposure assessment are required. Less
