Abstract: Изобретение относится к медицине, а именно к цитологии, гистологии, и может быть использовано для флуоресцентной цитохимической оценки адренореактивности в эритроцитах. Для этого осуществляют поэтапную обработку мазков периферической крови аутбредных крыс. При этом проводят одновременную фиксацию и окраску мазка в насыщенном 5% спиртовом растворе ализарина красного С. Затем осуществляют двойное отмывание препаратов в дистиллированной воде с последующим высушиванием. Дополнительно окрашивают в 5% водном растворе бихромата калия при необходимости, повторно отмывают в дистиллированной воде. Во время обработки проводят дополнительную фиксацию мазков крови в парах формалина. Затем проводят микроскопию окрашенных или неокрашенных мазков крови.
