Исследования проводили на половозрелых аутбредных мышах-самцах ICR, инбредных мышах-самцах С57Bl/6 и BALB/c. Определяли действие Pro-Gly на мышечную силу и уровень ситуационной тревожности аутбредных мышей ICR. Исследовали воздействие Pro-Gly на зоосоциальное поведение мышей ICR в трехкамерном аппарате для оценки социализации. Проводили оценку эффектов исследуемого дипептида в условиях модельной патологии, вызванной введением мышам С57Bl/6 и BALB/с неконкурентного блокатора N-метил-D-аспартатных рецепторов глутамата - МК-801. Pro-Gly статистически значимо повышало коммуникабельность лабораторных грызунов в условиях «нормы» (мыши аутбредные ICR и инбредные C57Bl/6). Мыши ICR, которым вводили Pro-Gly (0,5 мг/кг), проводили в камере с мышью на 40,4% больше времени, чем особи контрольной группы (398,5±42,7 с против 283,9±42,9 с соответственно) и отдавали предпочтение камере с мышью (398,5±42,7 с), нежели камере с Lego (89,9±38,3 с) - p&lt;0,05. Дипептид значимо повышал коммуникабельность мышей C57Bl/6: особи указанной линии на фоне введения Pro-Gly предпочитали большую часть времени проводить в камере с мышью (327,3±66,7 с), чем в камере с Lego (159,7±48,9 с; p&lt;0,05) или в центральной камере (113,0±25,9 с; p&lt;0,05). Заключение - дипептид Pro-Gly был эффективен в отношении зоосоциального поведения при введении коротким курсом (5-7-кратно), в условиях внутрижелудочного применения, что выгодно отличает его от окситоцина (используется интраназально). Перспективны дальнейшие исследования Pro-Gly при нарушениях социабельности.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the work was to study the effect of Pro-Gly (a dipeptide structurally similar to the Pro-Leu oxytocin fragment) on the zoosocial behavior of laboratory rodents.The studies were performed on adult outbred ICR male mice, inbred C57Bl/6 and BALB/c male mice. The effect of Pro-Gly on muscle strength and the level of situative anxiety in ICR mice was determined. The effect of Pro-Gly on zoosocial behavior of ICR mice was studied in a three-chamber apparatus for assessing the socialization. The effects of the studied dipeptide were evaluated in the conditions of model pathology caused by the administration of a non-competitive blocker of N-methyl-D-aspartate glutamate receptors - MK-801 to C57Bl/6 and BALB/c mice.Pro-Gly significantly increased sociability in rodents without behavioral disorders (outbred ICR and inbred C57Bl/6 mice). ICR mice after oral administration of Pro-Gly (0,5 mg / kg) spent 40,4% more time in the chamber with mouse than mice of the control group (398,5±42,7 s versus 283,9±42,9 s, respectively), and they preferred a camera with a mouse (398,5±42,7 s), rather than a camera with a Lego (89,9±38,3 s; p&lt;0,05). The dipeptide significantly increased the sociability of C57Bl/6 mice: individuals of this strain preferred to spend most of their time in the chamber with a mouse (327,3±66,7 s) than in the chamber with a Lego (159,7±48,9 s; p&lt;0,05) or in the central chamber (113,0±25,9 s; p&lt;0,05).Conclusion - dipeptide Pro-Gly is effective when administered in a short course (5-7-fold), with intragastric administration, which distinguishes it from OT (which is administered intranasally). Further studies of Pro-Gly in social disorder are promising.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Pro-Gly</kwd><kwd>МК-801</kwd><kwd>зоосоциальное поведение</kwd><kwd>мыши</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Pro-Gly</kwd><kwd>МК-801</kwd><kwd>zoosocial behavior</kwd><kwd>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">Методические рекомендации по доклиническому изучению транквилизирующего (анксиолитического) действия лекарственных средств / Т.А.
