Abstract
Abstract Today proved that the cause of many diseases are unfavorable conditions for the development of the fetus in the womb, caused by exposure to pregnant the toxicants of exogenous nature, which include nicotine, and a violation of its feeding. However, the literature does not answer the question - what is the impact of smoking on pregnant thyropathies development in the offspring. In an experimental model of the combined effects of passive smoking and to reduce energy intake food rats during pregnancy found that their descendants are characterized by a high percentage of deaths in the first months of life, delay physical and sexual development, and at 6 months of age, one-third of the children observed obesity. At the same time, in the offspring of mothers treated with cigarette smoke and having a reduced power during pregnancy, disturbed the dynamics and character formation histostructure and hormonal activity of the thyroid gland. This characteristic becomes microfollicular type of gland structure with hyperthyroidization during puberty, which is replaced by a hypothyroid state, destruction of the parenchyma, the appearance of lymphoid infiltration. Реферат Сегодня доказано, что причиной многих заболеваний являются неблагоприятные условия развития плода в утробе матери, вызванные воздействием на беременную токсикантов экзогенной природы, к которым относятся никотин, и нарушением ее питания. Но в литературе нет ответа на вопрос - каково влияние курения беременных на развитие тиреопатий у потомков. На экспериментальной модели комбинированного воздействия пассивного курения и снижения калоража питания крыс в течение беременности установлено, что для их потомков характерны высокий процент гибели в первые месяцы жизни, задержка соматического и полового развития, а в 6-месячном возрасте у трети потомков наблюдается ожирение. Одновременно, у потомков матерей обработанных дымом сигарет и имеющих редуцированное питание при беременности, нарушается динамика и характер формирования гистоструктуры и гормональной активности щитовидных желез. При этом характерным становится микрофолликулярный тип строения железы с гипертиреоидизацией в перипубертатном периоде, которая сменяется гипотиреоидным состоянием, деструкцией паренхимы, появлением лимфоидной инфильтрации.
