Ultrastructural organization of epiphysis in rats under the action of electromagnetic fields and during mammary carcinogenesi.

Experiments conducted by the authors, as well as clinical studies, show that in addition to hormonal mis-balance, development of mammary gland cancer is significantly influenced by the action of low frequency electromagnetic fields on epiphysis. By reducing the production of melatonin it increases the risk of development of mammary gland tumors. The review of scientific literature indicates that pinealocytes are the main morphological substrate responsible for functional activity of pineal cells.

Household electromagnetic fields and breast cancer in elderly women.

The relationship between the rate of household low-frequency electromagnetic fields (EMF) and incidences of mammary tumors was studied in 1290 clinical case-records of female patients aged 60 and more over a period of 26 years, based on the materials of the Edith Wolfson Medical Center, Israel. The studied material was divided into two groups, each corresponding to a period of 13 years. Group I included patients with mammary tumors under observation from 1978 to 1990, who rarely used EMF-generating appliances.

The role of household electromagnetic fields in the development of mammary tumors in women: clinical case-record observations.

Background: The relationship between the exposure rates to household EMFs and incidences of mammary tumors has been studied in women based on the materials of the Edith Wolfson Medical Center, Israel.

Material/methods: 200,527 biopsy and surgery samples from a period of 26 years were analyzed. The material was divided into two groups: Group 1 included patients with breast tumors from 1978 to 1990 and Group 2 between 1991 and 2003.

Morphology of experimentally induced tumors of the sympathetic nervous system in rats.

Seventeen tumors of the sympathetic nervous system were discovered in offspring of rats exposed in utero at a single dose of 80mg/kg of N-nitrosoethylurea at the day 16-19 of pregnancy, and then to constant light regimen. These tumors were classified as follows: benign--ganglioneuroma (six cases) and malignant--ganglioneuroblastoma (four cases) and neuroblastoma (seven cases). The most frequent location was in the sympathetic trunk in the mediastinum and in the retroperitoneal space.

Transplacental effects of high fat diets on functional activity of the spleen and lymph nodes, cell kinetics and apoptosis in mammary gland tumors in female rat offspring.

We studied whether feeding pregnant female rats different high fat diets affects structural zones in the spleen and lymph nodes, involved in production of T and B cells, as well as cell kinetics and apoptosis in some offspring with mammary glands tumors. Rat mothers were fed either a 7% or 15% corn-oil or a 7% or 15% olive-oil diet. At four weeks of age, female offspring (n=10-15 per group) were transferred to 7% corn oil diet.
