Оценить эффективность гормон-регулирующей синхронизации овуляции у самок мышей, для увеличения количества одновременно оплодотворенных особей и получения потомства в запланированные сроки.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Исследование было проведено на 180 самках мышей трех линий – CBA/lac, C57BL/6, BALB/c (n=60), разделенные на три подгруппы: интактные (спаривание без подтверждения фазы эструса) (n=20),цитологическое исследование вагинального секрета перед спариванием с определением фазы эструса(n=20), гормон-регулирующей синхронизации эстрального цикла с введением прогестерона (4,5 мг/100 г) на 1-е и простагландина F2α (0,083 мг/100 г) на 7-е сутки однократно от начала эксперимента с последующим немедленным спариванием(n=20). Запланированной датой родов считались 22 сутки с момента спаривания. Индекс синхронизации овуляции (ИСО) оценивался на 14 сутки с момента спаривания.</p></sec><sec><title>Результаты</title><p>Результаты. На 14-й день с начала эксперимента индекс синхронизации овуляции в интактных группах линий CBA/lac, C57BL/6, BALB/c составил 25%, 25%, 40% соответственно. Количество беременных особей на 14 сутки, допущенных к спариванию после установленного эструса методом цитологической оценки вагинального секрета согласно ИСО, составило 65%, 60%, 75% соответственно. В экспериментальных группах ИСО составил 80%, 75%, 100% соответственно. На 22 сутки количество родивших самок линий CBA/lac, C57BL/6, BALB/c в интактных группе составило 3, 1, 3 особи, в контрольных 10, 6, 9, а в экспериментальной группе 16, 15, 17 что достоверно выше чем в контрольных и интактных группах (p˂0,05).</p></sec><sec><title>Заключение</title><p>Заключение. Гормон-регулирующая синхронизация овуляции у самок мышей достоверно увеличивает количество разродившихся особей на 22 сутки относительно синхронизированных по эструсу животных на 53% и интакта на 85,5%. Выявлено, что дополнительным эффектом гормональной синхронизации овуляции является увеличение количества приплода в 2,2 раза в сравнении с контрольными группами и в 3,9 раз в сравнении с интактными группами. Данный способ планирования сроков рождения потомства экспериментальных животных сокращает временные затраты проведения доклинических исследований лекарственных препаратов по следующим видам оценки токсических эффектов: репродуктивная токсичность, эмбриотоксичность, тератогенность, влияние на фертильность. Кроме того, данный способ расширяет возможности экспериментального моделирования патологий беременности и плода с последующей оценкой их фармакологической коррекции.</p></sec></abstract><trans-abstract xml:lang="en"><p>The aim of the wok is to assess the efficiency of hormone-regulating synchronization of ovulation in female mice, to increase the number of simultaneously fertilized individuals and obtain their offspring in the planned time frame.</p><sec><title>Materials and methods</title><p>Materials and methods. The study was carried out on 180 female mice of three lines – CBA/lac, C57BL/6, BALB/c (n = 60), divided into three subgroups: intact (mating without confirmation of the estrous phase) (n = 20), cytological examination of vaginal secretions before mating with the determination of the estrous phase (n = 20), hormone-regulating synchronization of the estrous cycle with the introduction of progesterone (4.5 mg/100 g) on the 1st and prostaglandin F2α (0.083 mg/100 g) on the 7th day, once from the beginning of the experiment followed by immediate mating (n = 20). The planned date of delivery was considered the 22nd day from the moment of mating. The ovulation synchronization index (OSI) was assessed on the 14th day after mating.</p></sec><sec><title>Results</title><p>Results. On the 14th day from the beginning of the experiment, the ovulation synchronization index in the intact groups of the CBA/lac, C57BL/6, BALB / c lines, was 25%, 25%, 40%, respectively. On the 14th day, the number of pregnant individuals admitted to mating after the established estrus by the method of cytological assessment of vaginal secretions according to OSI, was 65%, 60%, 75%, respectively. In the experimental groups, OSI was 80%, 75%, 100%, respectively. On the 22nd day, the number of delivered females of CBA/lac, C57BL/6, BALB/c lines in the intact group, was 3, 1, 3 individuals; in the control group – 10, 6, 9, and in the experimental group – 16, 15, 17, which is significantly higher than in the control and intact groups (p˂0.05).</p></sec><sec><title>Conclusion</title><p>Conclusion. Hormone-regulating synchronization of ovulation in female mice significantly increases the number of delivered individuals on the 22nd day, relative to those synchronized by estrus by 53%, and to intact groups by 85.5%. It has been revealed that an additional effect of hormonal synchronization of ovulation is an increase in the number of offspring by 120% in comparison with the control groups and by 390% in comparison with the intact groups. This method of timing planning of the offspring birth of the experimental animals reduces the time spent on preclinical studies of drugs for the following types of assessment of toxic effects: reproductive toxicity, embryotoxicity, teratogenicity, effects on fertility.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>эстральный цикл</kwd><kwd>эструс</kwd><kwd>прогестерон</kwd><kwd>вагинальная цитология</kwd><kwd>синхронизация овуляции</kwd><kwd>простагландин F2α</kwd></kwd-group><kwd-group xml:lang="en"><kwd>estrous cycle</kwd><kwd>estrus</kwd><kwd>progesterone</kwd><kwd>vaginal cytology</kwd><kwd>ovulation synchronization</kwd><kwd>prostaglandin F2α</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Это исследование не получило какого-либо конкретного гранта от финансирующих учреждений в государственном, коммерческом или некоммерческом секторах</funding-statement><funding-statement xml:lang="en">This study did not receive any specific grant from funding agencies in the government, commercial or non-profit sectors.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Åhlgren J., Voikar V.
