Zusammenfassung:FIELD: medicine.SUBSTANCE: method includes the preparation of smear from peripheral blood with preliminary fixation with methyl alcohol, drying, washing with distilled water. After that, the smears are placed in a potassium chloride solution in a ratio of 0.57 g of potassium chloride per 100 ml of distilled water for 20 min and washed with distilled water. Additionally prepared is a mixture of solutions, prepared ex tempore, containing a solution "A" and "B". The solution "A" includes a 50% silver nitrate solution in an amount of 5 g of silver nitrate + 5 ml of distilled water. The solution "B" includes a 2% solution of gelatin on a 1% formic acid solution in an amount of 15.8 ml of distilled water + 0.2 ml of 100% formic acid + 4.0 ml of 10% gelatin. The solutions "A" and "B" are mixed in an amount of 5 ml of each, in darkness, with further submergence of the blood smears for 20 min in darkness in the thermostat at a temperature of 37°C with the further submergence of the smears into distilled water for 2-3 seconds. After that, they are twice subjected to a 8 min exposure in a 5% sodium thiosulphate solution in darkness in the thermostat at a temperature of 37°C. After that, they are washed successively with tap water and distilled water, after-staining is performed in the Romanovskiy dye for 30 min. After that, the smears are washed again with tap water, air-dried, placed in the Canadian balm and covered with a coverslip.EFFECT: increased quality of smear staining and provision of a possibility to identify and further evaluate parameters of nucleolus organiser regions.4 tbl, 6 ex Изобретение относится к ветеринарии и медицине, в частности к способу окраски мазков крови для микроскопического определения структурной организации и фаз активности клеток, и может быть использовано в цитофизиологии, цитопатологии и цитогенетике, а также рекомендовано к применению при проведении гематологических исследований при определении функционального состояния клеток крови. Способ включает приготовление мазка из периферической крови с предварительной фиксацией метиловым спиртом, высушивание, промывание дистиллированной водой. Затем мазки помещают в раствор хлорида калия в соотношении 0,57 г хлорида калия на 100 мл дистиллированной воды в течение 20 мин и промывают дистиллированной водой. Дополнительно готовят смесь растворов, приготовленных ex tempore, содержащую раствор «А» и «В». Раствор «А» включает 50% раствор азотнокислого серебра в количестве 5 г нитрата серебра + 5
