Abstract: Изобретение относится к медицине, а именно к гепатологии, и может быть использовано для поддержания функционального состояния цирротически измененной печени у пациентов в листе ожидания трансплантации органа. Производят доставку в печень аутологичных гемопоэтических стволовых клеток (CD133+ ГСК), которую осуществляют путем чрескожной неинвазивной механической вибрации на область печени в диапазоне 0.02-10 кГц, индуцирующей опосредованное высвобождение в кровь альфа-фетопротеин (афп+CD133+ГСК) гемопоэтических стволовых клеток. Мониторируют их содержание в лимфоцитах крови не реже одного раза в неделю методом проточной цитометрии до и во время курса вибрации по показателям абсолютного содержания афп+ CD133+ ГСК и относительного их содержания в общей фракции CD133+ГСК. При этом вибрацию осуществляют ежедневно один раз в день в течение 15 минут при амплитуде вибраций 10±2 мкм и длительности каждого цикла 60±10 сек. По достижению максимального увеличения хотя бы одного из этих показателей во время курса вибрации по сравнению с их значениями до него вибрационное воздействие заканчивают, продолжая мониторирование. В случае снижения достигнутых показателей вибрационное воздействие повторяют в тех же режимах. Способ обеспечивает специфичность по отношению к печени, неинвазивность - исключение хирургической травмы, а также возможность неоднократных повторений без причинения ущерба здоровью больного, находящегося в листе ожидания трансплантации печени. 2 табл., 2 пр.
