[Impact of Brownian motion and magnetic fields of erythrocytes on spin echo signal of blood protons]. / Vliianie brounovskogo dvizheniia i magnitnykh polei éritrotsitov na signal spinovogo ékha protonov krovi.

A reduction in blood So2 and ESR is shown to lead to the decay of a spin echo signal. This effect is explained by the impact of red blood cell magnetic field fluctuations caused by the Brownian motion. The authors propose to use the effect to monitor red blood cell agglutination.

[The use of flow cytofluorometry for determining antisperm antibodies by sperm immobilization and sperm toxicity methods]. / Ispol'zovanie protochnoi tsitofliuorometrii dlia opredeleniia antispermal'nykh antitel metodami spermoimmobilizatsii i spermotoksichnosti.

During antisperm antibody detection by conventional methods of immobilization and cytotoxicity investigators used flow cytometry to detect dead and/or immovable sperm cells. It was shown that after incubation of sperm cells with low antiserum dilution immovable spermatozoa are still living. Evidently, cytotoxicity test in this case brings about false-negative results. Therefore, flow cytometry will be a success for ASAB detection through immobilization test.
