Увеличение частоты встречаемости и длительности слип-апноэ у новорожденных связывают с пассивным курением матери во время беременности. Целью настоящего исследования являлось изучение особенностей респираторной и нереспираторной активности бульбоспинальных препаратов (БСП) мозга новорожденных крыс, перенесших пренатальное пассивное табакокурение. Исследование выполнено на БСП мозга новорожденных крыс (n=107) в условиях in vitro. Моделирование пассивного курения осуществлялось посредством фумигации сигаретным дымом самок экспериментальной группы (ПК) с 1 по 20 день беременности. Установлено, что у БСП мозга новорожденных крыс группы ПК (n=57) значения амплитуды и продолжительности инспираторных разрядов меньше аналогичных показателей контрольной группы (НК) в среднем на 16,1 и 10,9%, соответственно. Продолжительность респираторного цикла у БСП из группы ПК была на 15,3% меньше. Выявлено меньшее значение спектральной плотности мощности в низкочастотном (1-10 Гц) и среднечастотном (11-50 Гц) диапазонах в группе ПК по сравнению с группой НК на 16,3 и 33,4%, соответственно. Частота низкочастотного пика осцилляций группы ПК оказалась меньше, чем в контрольной группе, на 11,2%, частота среднечастотного пика - на 14,3%. Прочие параметры активности изменений не претерпевали. Кроме того, встречаемость сразу нескольких видов электрической активности значительно увеличивалась у БСП группы ПК. Таким образом, установлено, что в период пренатального развития респираторной нейронной сети долговременное периодическое действие факторов пассивного курения изменяет характер функционирования центральных механизмов генерации респираторного ритма и инспираторного паттерна у новорожденных крыс in vitro.</p></abstract><trans-abstract xml:lang="en"><p>The phenomenon of sleep apnea in infants is being studied widely at the moment. The increase of the frequency of occurrence and duration of sleep apnea in infants is associated with passive smoking during pregnancy. The aim of this study was to investigate the characteristics of respiratory and non-respiratory activity of bulbospinal preparations (BSP) of brain of newborn rats undergoing prenatal passive smoking. The study was performed on BSP in the brain of newborn rats (n=107) in vitro. Modeling of passive smoking was carried out by cigarette smoke fumigated into the females of the experimental group (PS) from 1 to 20 days of gestation. In BSP of newborn rats of the PS group (n=57), the amplitude and duration of the inspiratory discharges were less than in the control group (Non-S) by 16.1% and 10.9% on average, respectively. The duration of a respiratory cycle in the BSP of PS group was 15.3% lower. There were revealed lower values of the spectral power density in the low-frequency (1-10 Hz) and mid-frequency (11-50 Hz) bands in the PS group compared to Non-S group by 16.3% and 33.4%, respectively. The frequency of low-frequency oscillations of the peak in the PS group was less than in the control group by 11.2% and of mid-peak rate by 14.3%. Other parameters of activity did not undergo any changes. In addition, the incidence of several types of electrical activity is significantly increased in the BSP of PS group. Thus, it was found out that during the period of prenatal development of respiratory neural network, long-term cyclical factors of passive smoking alter the functioning of the central mechanisms of the generation of respiratory rhythm and pattern of inspiratory in neonatal rats in vitro.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>новорожденные крысы</kwd><kwd>дыхательный центр</kwd><kwd>in vitro</kwd><kwd>пассивное курение</kwd><kwd>бульбоспинальный препарат</kwd><kwd>newborn rats</kwd><kwd>the respiratory center</kwd><kwd>in vitro</kwd><kwd>passive smoking</kwd><kwd>bulbospinal preparation</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">Особенности спектральных характеристик электрической активности дыхательного центра в процессах мозга плодов и новорожденных крыс in vitro / И.В.Мирошниченко, В.Ф.Пятин, А.С.Алексеева, Н.Л.Тюрин // Рос. физиол. журн. им.
