В работе приводятся данные экспериментального подтверждения и физиологическое объяснение феномена Фареуса-Линдквиста в капиллярах, используя анализ профилей осмотической деформируемости красных клеток крови. Показано дозозависимое изменение деформируемости эритроцитов в стадии изотропной сферы при формировании искусственных водных пор (нистатин) и закупорке (PbCl2) имеющихся. Сигма-эффект снижения гематокрита и вязкости в сдвиговом потоке крови через сосуды малого диаметра вызывается обменом жидких фаз между эритроцитом и плазмой.
