[Informative value of the studies of beta 2-microglobulin in the plasma and urine of humans for evaluation of the resistance to static and bicycle ergometry tests].

Abstract

Changes of the beta 2-microglobulin concentration in blood and urine were measured in response to static and bicycle ergometry tests. In both cases, the concentration of beta 2-microglobulin in urine increased. A higher level of its renal excretion was seen in stable subjects before and after the tests. This relationship was also seen in patients with neurocirculatory dystonia of the hypertensive type. Possible mechanisms of these reactions are discussed.
