Характеристика иммунного статуса крыс при витаминно-минеральной недостаточности

Abstract

В статье представлены результаты исследования иммунного статуса крыс в условиях различных уровней обеспеченности витаминами группы В (В1, В2, В3, В6) и минеральными веществами (Fe3+ и Mg2+). Самцы крыс линии Вистар (с исходной массой тела 90-110 г) в течение 65 дней получали модельные рационы с 75, 30 и 19% содержанием этих эссенциальных веществ, самки (с исходной массой тела 56 -76 г) рационы с 75, 28 и 18% содержанием. Были изучены некоторые показатели гуморального и клеточного звеньев иммунитета, включавшие подсчет лейкоцитарной формулы, измерение лизоцимной активности сыворотки крови, определение содержания иммуноглобулинов IgG, IgE, анализ цитокинового профиля сыворотки крови, а также определение массы органов иммунной системы. Показано, что снижение содержания витаминов группы В, железа и магния в рационе не вызывает комплексных изменений иммунного статуса крыс, поэтому предложенная модель изменения адаптационного потенциала не является оптимальной для изучения состояния системы иммунитета. Проведенные масштабные исследования иммунного статуса крыс (изучено 18 показателей, выборка из 90 самцов и 90 самок) позволяют установить диапазон физиологических колебаний этих показателей у крыс линии Вистар соответствующего пола и возраста.

The article presents the results of rats’ immune status evaluation in conditions of different levels of B vitamins (B1, B2, B3, B6) and minerals (Fe3+ and Mg2+) supplying. Male Wistar rats (with initial body weight 90-110 g) within 65 days received model diets with 75, 30 and 19% content of the essential substances, females (with initial body weight 56-76 g) received diets with 75, 28 and 18% content. Some indicators of humoral and cellular immunity, including leukocyte count, lysozyme serum activity, IgG and IgE level, cytokine profile of blood serum and of the masses of the immune system internal organs have been examined. It has been shown that the decrease in the content of B vitamins, iron and magnesium in the diet didn’t cause complex changes of the rats’ immune status, therefore, the proposed model of adaptive potential change is not optimal for studying of immune system condtion. The extensive research of the immune status of rats (18 studied indicators, a sample of 90 males and 90 females) allows to set the range of physiological fluctuations of these indexes in Wistar rats of the corresponding gender and age.
