Изучение изменения патофизиологических параметров роста перевивной опухоли и функциональной активности гипоталамо-гипофизарно-тиреоидной оси (ГГТ) у крыс обоего пола с карциномой Герена на фоне индуцированного гипотиреоза.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. У белых беспородных крыс обоего пола с подкожно перевитой карциномой Герена на фоне индуцированного тиреостатиком гипотиреоза (основная группа) изучали динамику роста опухоли и среднюю продолжительность жизни, радиоиммунным и иммуноферментным методами (РИА и ИФА) определяли содержание тиреоидных гормонов в крови, щитовидной железе и в образцах опухоли, тиреотропного рилизинг гормона в гипоталамусе и тиреотропного гормона (ТТГ) в гипофизе. В эксперименте использовали 2 контрольные группы: животные обоего пола с гипотиреозом –контрольная группа № 1 (по 15 животных) и контрольная группа № 2–самостоятельный рост опухоли – подкожная перевивка карциномы Герена (по 15 животных).</p></sec><sec><title>Результаты</title><p>Результаты. У самок крыс гипотиреоз вызвал торможение роста перевивной опухоли и увеличение средней продолжительности жизни в 1,8 раза (р &lt; 0,05). У самцов основной группы подобного эффекта не наблюдали. У самок основной группы установлено снижение уровня регуляторных пептидов гипоталамуса и гипофиза, тогда как у самцов уровень ТТГ в гипофизе повышался несмотря на снижение ТГ-рилизинга в 3,5 раза. В щитовидной железе и крови у животных обоего пола установлено снижение содержания ТГ, однако в опухоли установлено падение уровня общего и свободного тироксина (Т4 и FT4) в 1,6 раза и в 2,8 раза соответственно, образцы карциномы Герена у самцов основной группы оставались насыщенными Т4 и FT4 также, как и в контрольной, у животных без индуцированного гипотиреоза.</p></sec><sec><title>Заключение</title><p>Заключение. Выявленные в настоящем исследовании половые различия в патофизиологии течения злокачественного процесса на фоне гипотиреоза, а также изменения функциональной активности ГГТ оси у экспериментальных животных, вероятно, могут быть связаны с половыми гормонами, что требует дальнейшего исследования гипоталамогипофизарно-гонадной (ГГГ) оси и показателей стероидных гормонов в периферических органах и образцах опухоли. </p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Purpose of the study</title><p>Purpose of the study. Was to analyze changes in pathophysiological parameters of transplantable tumor growth and functional activity of the hypothalamic-pituitary-thyroid axis (HPT) in rats of both sexes with Guerin's carcinoma in presence of induced hypothyroidism.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The dynamics of tumor growth and average life span were assessed in white alley rats of both sexes with Guerins carcinoma transplanted subcutaneously on the background of thyreostatic induced hypothyroidism. RIA (radioimmune assay) and ELISA (enzyme-linked immunosorbent assay) methods were used to determine levels of thyroid hormones in the blood and thyroid and tumor samples, and thyrotropin-releasing hormone (TRH) in the hypothalamus, as well as TSH in the pituitary gland. The experiment included 2 control groups: animals of both sexes with hypothyroidism (control group 1, number of rodents = 15) and animals with subcutaneously transplanted Guerin's carcinoma without hypothyroidism (control group 2, number of rodents = 15).</p></sec><sec><title>Results</title><p>Results. Hypothyroidism in female rats inhibited the tumor growth and improved median survival by 1.8 times (p &lt; 0.05). No such effect was observed in males of the main group. Levels of regulatory peptides of the hypothalamus and pituitary gland declined in females of the main group, while levels of TSH in the pituitary gland in males increased, despite a decrease in TRH by 3.5 times. TSH levels decreased in the thyroid and blood of animals of both sexes; however, a decrease in levels of total and free circulating thyroxine (T4 and FT4) by 1.6 times and by 2.8 times was found in the tumor, respectively; samples of Guerin's carcinoma in males of the main group remained saturated with T4 and FT4 as well as and in control group rodents without induced hypothyroidism.</p></sec><sec><title>Conclusions</title><p>Conclusions. The gender differences in the pathophysiology of the tumor development in presence of hypothyroidism, as well as changes in the functional activity of the HPT axis in experimental animals revealed in this study can probably be associated with sex hormones, which requires further study of the hypothalamic-pituitary-gonadal (HPG) axis and steroid hormones in peripheral organs and tumor samples. </p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>карцинома Герена</kwd><kwd>гипотиреоз</kwd><kwd>гипоталамо-гипофизарно-тиреоидная ось</kwd><kwd>тиреоидные гормоны</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Guerin's carcinoma</kwd><kwd>hypothyroidism</kwd><kwd>hypothalamic-pituitary-thyroid axis</kwd><kwd>thyroid hormones</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">Barr CE, Njoku K, Hotchkies L, Ryan NAJ, Wan YL, Davies DA, et al.
