Effects induced by a 50 Hz electromagnetic field and doxorubicin on Walker-256 carcinosarcoma growth and hepatic redox state in rats.

We compare the effects of an extremely low-frequency electromagnetic field (EMF) with the chemotherapeutic agent doxorubicin (DOX) on tumor growth and the hepatic redox state in Walker-256 carcinosarcoma-bearing rats. Animals were divided into five groups with one control (no tumor) and four tumor-bearing groups: no treatment, DOX, DOX combined with EMF and EMF. While DOX and DOX + EMF provided greater inhibition of tumor growth, treatment with EMF alone resulted in some level of antitumor effect ( < .

[Allocation of precursor germinal cells from the tissue of the human ovaries].

The article present the results of a study on the allocation of precursor germinal cells from tissue of human ovaries obtained during various gynecological operations. Two series of cell culture were isolated from tissue of tunica albuginea. The cell lines were identified and characterized by PCR012-method, immunocytochemical staining and histological examination.

[Bacteria of the citrobacter genus as one of the possible indeices of dysbacteriosis in intestinal diseases].

A study of the incidence of detection of bacteria of the Citrobacter genus in chronic intestinal diseases with the clinical and bacteriological manifestations of dysbacteriosis indicated that the mentioned conditioned pathogenic bacteria were revealed with the same frequency as bacteria of the Proteus genus which served as the commonly accepted index of intestinal dysbacteriosis. Comparative analysis of the intestinal microbial flora of the patients led to a supposition that bacteria of the Citrobacter genus could be found not only in the associations with other microbes, but also as a definite individual group of bacteria during the infectious disease and antibiotic therapy in case of disturbance of normal intestinal biocenosis; this could occur even in the absence in these patients of the known bacteriological indices of dysbacteriosis, thus becoming one of its manifestations.
