[New informative index of the functional status of polymorphonuclear neutrophils]

A new test was applied to study the function of polymorphonuclear neutrophils according to their ability to form oreols in a hypertonic medium. During inhibition of neutrophil function in vivo (desympathetization, tumor growth), oreol formation increased. Stimulation of neutrophils in vitro by adding noradrenaline to the incubation medium led to a decrease in their oreol-forming ability. The data obtained enabled the authors to offer the test for detecting the functional activity of polynuclear cells.
