[Prevention of experimental allergic encephalomyelitis in guinea pigs by treatment with magnetophores]. / Predotvrashchenie éksperimental'nogo allergicheskogo éntsefalomielita u morskikh svinok vozdeistviem magnitoforov.

Subcutaneous application of magnetophores with a field intensity of 210 ersted prevented the development of experimental allergic encephalomyelitis (EAE) in guinea-pigs. The magnetophores appeared efficacious both at the beginning of the induction period and in the second half of the latent period, i.e. within the first two weeks after injection of encephalitogenic suspension. Application of magnetophores after the appearance of the neurological signs of EAE was ineffective. Magnetophores did not affect cellular or humoral response in animals. It may be assumed that the effect of magnetophores is related to the increased resistance of nerve cells to the immunopathological action of the immune response factors, a topic for further studies.

[Dimethylpolysiloxane reinforced film in a membrane oxygenator]. / Dimetilpolisiloksanovaia armirovannaia plenka v membrannom oksigenatore.

With the purpose of diffuse membranous oxygenation of blood the possibility of employing a Soviet-made dimethylpolyxyloxane-reinforced film "Sigma" was investigated. The test-trials were carried out with a membranous oxygenator of the "Sandwich" type. In 15 acute tests on dogs a partial cardio-pulmonary pass-by shunting with oxygenation of the blood after the veno-venous or veno-arterial perfusion was performed. With the mass-exchange area of 1.15 m2 the oxygen transport in different tests varied within a range of 20-50 ml/min and depended upon the arterio-venous difference and the circulation rate. No disruptions in the elimination of carbon dioxide were in evidence. In the course of investigations the "Sigma" material was found to be strong, impermeable to liquids and is not subject to swelling following its long-term use.
