Материал и методы. Работа выполнена на 72 белых крысах-самцах с начальной массой тела 130–150 г в возрасте 3 мес. Воздействие формальдегидом в концентрации 2,766 мг/м3 осуществлялись ежедневно в течение 60 мин. от 10 до 90 дней в разных группах наблюдения. Измерялись масса тела животных, абсолютная и относительная масса и размеры вилочковой железы. Проведен регрессионный анализ зависимости длины органа от его ширины. Результаты. Средний показатель абсолютной массы тимуса крыс, подвергавшихся воздействию формальдегида в течение 20 дней, составил 224,17 мг, что было на 14,9 % ниже значений контроля. Созданная модель зависимости длины тимуса от его ширины описывается формулой Y=2,7+1,25×Х, где Y – длина, а X – ширина. Заключение. В результате влияния формальдегида наблюдается снижение абсолютной массы тимуса. При этом его относительная масса не отличается от показателей соответствующей нормы. Воздействие на организм крыс формальдегида приводит к уменьшению размеров вилочковой железы. Созданная модель зависимости длины тимуса от его ширины позволяет прогнозировать значения зависимой переменной.</p></abstract><trans-abstract xml:lang="en"><p>Objective: to conduct organometry of thymus gland of white rats which were in the conditions of inhalation exposure to formaldehyde, and to build a regression model of the relationship between the length and width of the organ.Methods: The study was done on 72 white male rats with initial body weight 130–150 g, aged 3 months old. Exposure to formaldehyde at a concentration of 2.766 mg /m3 was carried out daily for 60 minutes from 10 to 90 days in different observation groups. We measured the body weight of animals, the absolute and relative weight and size of the thymus gland. A regression analysis of the dependence of the length of the body on its width was carried out.Results: The average absolute mass of the thymus of rats exposed to formaldehyde for 20 days was 224.17 mg, which was 14.9 % lower than the control values. The created model of dependence of the thymus length on its width is described by the formula Y=2.7+1.25×X, where Y is the length and X is the width.Conclusions: As a result of the influence of formaldehyde, a decrease in the absolute mass of the thymus is observed. However, its relative mass does not differ from the indicators of the corresponding norm. Formaldehyde exposure to rats leads to reduction of the size of the thymus gland. The created model of dependence of the thymus length on its width allows predicting the values of the dependent variable.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>крыса</kwd><kwd>вилочковая железа</kwd><kwd>формальдегид</kwd><kwd>регрессионный анализ</kwd></kwd-group><kwd-group xml:lang="en"><kwd>rat</kwd><kwd>thymus gland</kwd><kwd>formaldehyde</kwd><kwd>regression analysis</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">Асфандияров Р.И., Удочкина Л.А., Санджиев С.А.
