ACCELERATION OF MAMMARY TUMORIGENESIS BY EXPOSURE OF 7,12-DIMETHYLBENZ\[a]ANTHRACENE-TREATED FEMALE RATS IN A 50-Hz, 100-muT MAGNETIC FIELD: REPLICATION STUDY

摘要: In view of the methodological problems epidemiological studies on associations between residential and occupational exposures to 50/ 60-Hz magnetic fields (MF) increased incidence cancers, laboratory are necessary determine if 50/60-Hz MF can affect cancer development or growth. Recently, it was reported that alternating (50-Hz) low flux density (100 muT) increase tumor growth progression in a model breast female rats which mammary tumors were induced by chemical carcinogen 7,12-dimethylbenz\[a]anthracene (DMBA). The objective present study replicate experiment carried out same under experimental conditions yields significant similar magnitude. For experiment, group 99 Sprague-Dawley exposed homogeneous horizontally polarized for 24 h/ d (minus time weighing, palpation, cage cleaning, rotation), 7 d/wk; a...
