Characteristic of the rats' immune status during vitamin and mineral deficiency
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.
