Материалы и методы: эксперименты проведены на 80 наркотизированных нелинейных крысах-самцах (массой 250-350гр), разделенных на два экспериментальных протокола. Протокол 1. Было набрано 30 новорожденных крысят, которые были разделены на контрольные и опытные группы. В опытных группах животным с целью дегенерации чувствительных С-волокон в неонатальном периоде вводили капсаицин (п=15). По достижении массы 250 гр, животные подвергались 30-минутной ишемии и 120-минутной реперфузии миокарда (группы Контроль-ОИМ, п=7, Капсаицин-ОИМ, п=6) или двухсторонней 15-минутной окклюзии бедренных артерий, предшествующей ишемии и реперфузии миокарда (Контроль-ДИПК, п=8, Капсаицин-ДИПК, п=9). Протокол 2. Крысы первой группы подвергались 30-минутной ишемии миокарда с последующей 120-минутной реперфузией (группа Контроль, п=10). Животным второй и третьей групп за 25 минут до начала ишемии (группа ДИПК, п=10) и на 25-й минуте ишемии (группа ДИПК25', п=10) выполнялась двухсторонняя 15-минутная окклюзия бедренных артерий. Животным четвертой и пятой групп осуществляли подкожное введение капсаицина за 25 минут до начала ишемии и на 25-й минуте ишемии (группы Капсаицин, п=10 и Капсаицин25', п=10). Результаты: Протокол 1. В группах животных, которым выполнялась 30-минутная ишемия, сопровождающаяся 120-минутной реперфузией, размеры некроза миокарда были сопоставимы и составили 45±4% и 43±1% (группы Контроль-ОИМ и Капсаицин-ОИМ соответственно). В группе Капсаицин-ДИПК не наблюдалось уменьшения размера некроза по сравнению с группой Капсаицин-ОИМ (р&gt;0,05). Протокол 2. Размер некроза в контрольной группе составил 42±1%. Отмечалось значимое уменьшение размера зоны некроза в группах, в которых окклюзия бедренных артерий выполнялась за 25 минут до начала острой ишемии и начиная с 25 минуты ишемии, а также у животных, которым за 25 минут до начала коронарной окклюзии вводился капсаицин по сравнению с контрольной группой (19±1%, 18±2% и 25±1%, соответственно, р&lt;0,001). При введении капсаицина на 25-й минуте ишемии противоишемический эффект отсутствовал, размер некроза составил 42±4% (р&gt;0,05 в сравнении с группой Контроль). Заключение: полученные результаты свидетельствуют о том, что чувствительные С-волокна участвуют в развитии противоишемического эффекта ДИПК, осуществляемого до начала острой ишемии миокарда, однако, не играют роли ключевого звена в развитии кардиопротекторного эффекта ДИПК, воспроизводимого с 25-й минуты ишемии по 10-ю минуту реперфузии.</p></abstract><trans-abstract xml:lang="en"><p>To evaluate the role of C-fibers in the development of cardioprotective effect of remote ischaemic preconditioning (RPc) during myocardial ischaemia and reperfusion. Materials and methods: experiments have been conducted on 80 anaesthetized Wistar male rats (250-350g weight), divided into two experimental protocols. Protocol 1. The protocol included 30 neonatal rats, which were divided into two groups. In the first group (n=15), capsaicin was injected to animals in neonatal period in order to degenerate sensitive C-fibers. When achieved 250g, the rats were subjected to 30 min myocardial ischaemia and 120 min reperfusion (Control-AMI, n=7, Capsaicin-AMI, n=6) or 15-min both femoral arteries occlusion 25 min before coronary artery occlusion (Control-RPc, n=8; Capsaicin-RPc, n=9). Protocol 2. The first group of animals (Control) was subjected to 30-min myocardial ischaemia with following 120-min reperfusion only. In the second and third animal group 15-min bilateral femoral arteries occlusion was performed 25 min before the onset (RPc group) or 25 min after the onset (RPc25' group) of ischaemia. The animals of the fourth and fifth groups capsaicin was injected subcutaneously 25 min before the onset and on the 25 min after the onset of ischaemia (Capsaicin and Capsaicin25'groups). Results: Protocol 1. Infarct size was comparable in Control-AMI and Capsaicin-AMI groups (45±4% and 43±1%) respectively. No infarct size reduction was observed in Capsaicin-RPc group compared to Capsaicin-AMI group (p&gt;0,05). Protocol 2. Significant reduction in infarct size was observed in groups, where femoral arteries occlusion was performed 25 min before the onset and on the 25th min after the onset of ischaemia, as well as in those, where capsaicin was injected before myocardial ischaemia, comparing to control group (p&lt;0,001). There was no infarct-size reduction if capsaicin was injected on the 25th min of ischaemia (p&gt;0,05 vs. Control). Conclusions: the results suggest that activation of С-fiber afferents by topical application of capsaicin to the peripheral tissue prior to myocardial ischaemia/reperfusion limits myocardial injury, mimicking the effect of remote preconditioning, but it doesn't play a key role in the development of RPc applied 25 min after the onset of ischaemia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дистантное ишемическое прекондиционирование</kwd><kwd>ишемическое и реперфузионное повреждение миокарда</kwd><kwd>капсаицин</kwd><kwd>С-волокна</kwd><kwd>remote ischaemic preconditioning</kwd><kwd>ischaemia and reperfusion injury of myocardium</kwd><kwd>coronary artery occlusion</kwd><kwd>capsaicin</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">MagiII P., Murphy Т., Bouchier-Hayes D.
