[Erythropoietin in non-specific intestinal inflammation].

In 39 patients with non-specific intestinal inflammations the authors examined the erythropoietin level. They found a significantly higher level of serum erythropoietin in patients during relapse, when the organism responds to more severe anaemia by increased erythropoietin production. The idea that the reactivity of the bone marrow or effectiveness of erythropoietin is influenced by mediators of the inflammation is supported by the fact that the group comprised patients with high erythropoietin values of 102, 106.

Evaluation of the biological effects of police radar RAMER 7F.

This paper presents results of experiments on the effects of electromagnetic radiation in the millimeter range (frequency 34.0 +/- 0.1 GHz, power density 20 muW/cm2) emitted by a police radar device.

Effects of microwaves on membranes of hematopoietic cells in their structural and functional organization.

The role of cell membranes in stimulating and inhibiting the effects of microwaves was investigated in experiments carried out with a suspension of murine bone marrow cells irradiated with microwaves in vitro [f = 2.45 GHz, CW, specific absorption rate (SAR) = 12 W/kg]. Results obtained by means of a structural probe, 2.

Amelioration of radiation damage to haemopoiesis by Ivastimul, given after irradiation to mice protected by peroral cystamine.

The combined radioprotection by preirradiation peroral cystamine and postirradiation Ivastimul treatment was examined in sublethally and lethally whole-body gamma-irradiated mice. The enhancement of haemopoietic recovery and increased survival of irradiated mice was demonstrated when a single dose of Ivastimul was administered after irradiation. Ameliorative influence of combined radioprotection may be explained by the haemopoietic stem cell protection by cystamine and haemopoietic stimulation mediated by Ivastimul.

Production of anti-SRBC antibodies after DDC administration in whole-body irradiated mice.

Production of antibody-forming cells (PFC) was studied in mice subjected to a single whole-body irradiation dose of 3.8 Gy after sodium diethyldithiocarbamate (DDC, 800 mg/kg) injected 30 min before irradiation. Animals were immunized (1% SRBC) 4 h, 5 and 10 days after irradiation, and the number of PFC was determined by a modified Jerne plaque technique on days 4, 7 and 10 after immunization.
