Цель исследования - морфометрия нейронов префронтальной коры половозрелых белых лабораторных крыс после острого звукового воздействия в условиях питания малобелковой пищей. Эксперименты проведены на 64 половозрелых нелинейных белых лабораторных крысах-самцах масссой 180-230 грамм (8 – интактных, 56 – экспериментальных). После однократного непрерывного звукового воздействия интенсивностью 120 db в течении 120 секунд 56 крыс разделены на 2 группы: со сбалансированной пищей (контрольная - 28) и малобелковой пищей (основная – 28); с двумя подгруппами в каждой из них: стресс-устойчивые (по 12) и стресс-неустойчивые (по 16). Животные из эксперимента выведены были на 10-е, 20-е, 30-е и 40-е сутки после начала эксперимента. Образцы препаратов префронтальной коры изучены гистологически, иммуногистохимически и морфометрически. После однократного острого звукового воздействия изменяются показатели площади цитоплазмы, ядра и ядрышек нейронов префронтальной коры белых лабораторных крыс. Происходит хроматолиз субстанции Ниссля в большинстве нейронов II-III слоев нейронов. Во всех сроках наблюдений морфометрические изменения наиболее выражены у стресс-неустойчивых животных основной группы опытов, особенно – в первые 10 суток после воздействия. Хроматолиз в нейронах префронтальной коры остается до конца эксперимента, что свидетельствует о незавершенности репарации внутриклеточной белоксинтезирующей функциональной системы после острого звукового стресса. Таким образом, острое звуковое воздействие вызывает морфометрические изменения нейронов и инициирует хроматолиз субстанции Ниссля в них во II-III слоях коры префронтальной области головного мозга белых лабораторных крыс. Хроматолиз у животных с малобелковой пищей после острого звукового воздействия во II-III слоях префронтальной коры имеет необратимый характер, остается статистически значимо высоким и может расцениваться как проявление декомпенсации структурных изменений у животных в условиях дефицита белков в пище.</p></abstract><trans-abstract xml:lang="en"><p>Morphometric changes in neurons in the prefrontal cortex of white laboratory rats under conditions of protein deficiency in food after acute sound exposure remain unexplored. Purpose: morphometry of neurons in the prefrontal cortex of sexually mature white laboratory rats after acute sound exposure in conditions of low-protein food. The experiments were carried out on 64 sexually mature nonlinear white laboratory male rats weighing 180-230 g (8 - intact, 56 - experimental). After a single continuous sound exposure with an intensity of 120 dB for 120 seconds, 56 rats were divided into 2 groups: with balanced food (control - 28) and low-protein food (main food - 28); with two subgroups in each: stress-resistant (12) and stress-nonresistant (16). The animals were removed from the experiment on days 10, 20, 30 and 40 after the start of the experiment. Samples of prefrontal cortex preparations were examined histologically, immunohistochemically, and morphometrically. After acute sound exposure, the indicators of the area of ​​the cytoplasm, nucleus and nucleoli of neurons in the prefrontal cortex of white laboratory rats change. Chromatolysis of Nissl's substance occurs in most neurons of the II-III layers of neurons. During all periods of observation, morphometric changes were most pronounced in stress-nonresistant animals of the main group of experiments, especially in the first 10 days after exposure. Chromatolysis in neurons of the prefrontal cortex persists until the end of the experiment, which indicates incomplete repair of the intracellular protein-synthesizing functional system after acute sound stress. Thus, an acute sound effected causes morphometric changes in neurons and initiates chromatolysis of Nissl's substance in them in layers II-III of the cortex of the prefrontal region of the brain of white laboratory rats. Chromatolysis in animals with low-protein food after acute sound exposure in the II-III layers of the prefrontal cortex is irreversible, remains statistically significantly high and can be regarded as a manifestation of decompensation of structural changes in animals under conditions of protein deficiency in food.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>префронтальная кора</kwd><kwd>нейроны</kwd><kwd>звуковой стресс</kwd><kwd>малобелковая диета</kwd><kwd>крысы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>prefrontal cortex</kwd><kwd>neurons</kwd><kwd>sound stress</kwd><kwd>low protein diet</kwd><kwd>rats</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">Euston DR, Gruber AJ and McNaughton BL.
