title: Silver nucleolar organizer region assessment in tumor-cells from breast-cancer patients treated by extremely-low-frequency magnetic-field.
abstract: This study assessed the value of silver staining of nucleolar organizer regions (AgNORs) in tumor cells as a potential technique for the estimation of the action of ELF magnetic field on breast cancer. The light and electron microscopy was used for analysis of tissue specimens from 4 breast cancer patients after ELF magnetotherapy and 18 untreated persons with malignant and benign breast lesions. All patients had surgical removal of neoplasms. The mean number of AgNORs and the distribution of cells according to the AgNOR number in tissue samples from patients after successful ELF magnetotherapy were closer to those of persons with benign tumors, as compared to malignant ones. The effect of ELF magnetic field at the electron microscopic level is discussed.
