Цикло-L-пролилглицин (ЦПГ), обнаруженный как эндогенное соединение в ЦНС, вовлечён в формирование реакции на эмоционально-стрессовое воздействие у животных с выраженной реакцией страха и обладает анальгетическим действием в опытах in vivo, однако данные о зависимости антиноцицептивного действия ЦПГ от генотипа в настоящее время отсутствуют.</p><p>Цель работы — оценить влияние экзогенного ЦПГ на пороги острой болевой реакции и вызываемую морфином анальгезию у мышей с противоположной реакцией на эмоциональный стресс.</p></sec><sec><title>Методы</title><p>Методы. Эксперименты выполнены на инбредных мышах-самцах линий BALB/c (n = 207) и С57Bl/6 (n = 204). Для оценки анальгетического действия ЦПГ использовали тест «уксусные корчи» (0,75 % раствор уксусной кислоты, в/б) и тест «горячая пластина» (55±0,5 °С).</p></sec><sec><title>Результаты</title><p>Результаты. ЦПГ в дозах 1, 2 и 4 мг/кг, в/б, статистически значимо снижал количество корчей у мышей BALB/c и C57Bl/6, при этом действие ЦПГ было сопоставимо с эффектом диклофенака в дозе 10 мг/кг, в/ж. При термической стимуляции выявлены межлинейные различия в антиноцицептивном действии ЦПГ, которое в максимально эффективной дозе 2 мг/кг было более выраженным у «стресс-неустойчивых» мышей BALB/c по сравнению с мышами C57Bl/6. ЦПГ в дозе 2 мг/кг ослаблял морфин-индуцированную анальгезию при термической стимуляции у мышей BALB/c и C57Bl/6 на 30, 60 и 90 мин наблюдения.</p></sec><sec><title>Заключение</title><p>Заключение. Установленная зависимость центрального антиноцицептивного эффекта ЦПГ от генотипа имеет важное значение в контексте биомедицинских исследований выявления боли и обеспечения контроля над ней с помощью фармакологических корректоров.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Relevance</title><p>Relevance. Cyclo-L-prolylglycine (CPG), discovered as an endogenous compound in the central nervous system, is involved in the formation of a reaction to emotional stress in rodents with a pronounced fear reaction and has an analgesic effect in vivo. However, data on the dependence of the antinociceptive effect of CPG on genotype are currently unavailable.</p></sec><sec><title>Objective</title><p>Objective. To evaluate the effect of exogenous CPG on the thresholds of acute pain response and morphine–induced analgesia in mice with an opposite reaction to emotional stress.</p></sec><sec><title>Methods</title><p>Methods. The experiments were performed on inbred male mice BALB/c (n = 207) and C57Bl/6 (n = 204). To assess the analgesic effect of CPG, the "writhing test" (0.75 % acetic acid solution, i.p.) and the "hot plate" (55 ± 0.5 °C).</p></sec><sec><title>Results</title><p>Results. CPG at doses of 1, 2, and 4 mg/kg, i.p., significantly reduced the number of writhings in BALB/c and C57Bl/6 mice, whereas the effect of CPG was comparable to that of diclofenac at a dose of 10 mg/kg per os. During thermal stimulation, interline differences in the antinociceptive effect of CPG were revealed, which was more pronounced at a maximum effective dose of 2 mg/kg in "stress-non-resistant" BALB/c mice compared with C57Bl/6 mice. CPG at a dose of 2 mg/kg weakened morphine-induced analgesia during thermal stimulation in BALB/c and C57Bl/6 mice for 30, 60, and 90 minutes of observation.</p></sec><sec><title>Conclusion</title><p>Conclusion. The established dependence of the central antinociceptive effect of CPGs on genotype is important in the context of biomedical research on pain detection and control using pharmacological correctors.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>цикло-L-пролилглицин</kwd><kwd>болевая реакция</kwd><kwd>морфин</kwd><kwd>анальгезия</kwd><kwd>мыши BALB/c и C57Bl/6</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cyclo-L-prolylglycine</kwd><kwd>pain response</kwd><kwd>morphine</kwd><kwd>analgesia</kwd><kwd>BALB/c and C57Bl/6 mice</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">Reimann F, Cox JJ, Belfer I, et al.
