The purpose of our experiment was to study the effect of the combined administration of an immunomodulator and a synthetic analogue of estrone to cows 3-5 days before calving on the colostral immunity of calves. The result of the work showed that the calves obtained from such cows have a greater number of leukocytes, T-lymphocytes and B-lymphocytes at birth. A synthetic analogue of estrone probably cross the placenta and affect the fetus, which is reflected in the acceleration of the metabolism of the newborn. As a result, there was an accelerated assimilation of colostrum from the gastrointestinal tract, which was reflected in a sharp increase in the fractions of β- and γ-globulins one hour after drinking colostrum. In addition, the number of T-lymphocytes and B-lymphocytes has sharply increased.

For the purpose of examining more closely the interaction between T and B lymphocytes, we have developed an in vitro T lymphocyte-dependent B lymphocyte proliferation assay. Proliferation of B lymphocytes in response to antigen was found to depend on the presence of primed T lymphocytes; the B lymphocytes could be derived from nonprimed animals. It appears that these B cells were nonspecifically recruited to proliferate. This nonspecific recruitment, however, was found to be Ir-gene restricted in that B lymphocytes from B10.S mice, which are genetic nonresponders to the polymer Glu60-Ala30-Tyr10 (GAT), could not be stimulated by GAT-primed (responder X nonresponder) F1 T cells. The apparent lack of antigen specificity in the face of Ir gene-restricted T-B interaction may have important implications in our understanding of the recognition unit(s) on T lymphocytes.

The results of research on the influence of the elaborated complex immunotropic drug containing butafosfan, interferon, thistle and fat-soluble vitamins A, D3, E in the form of a liposomal emulsion on the activity of T- and B-cell chains of immunity in rats under the conditions of action on the body of oxidative stress are presented. It has been established that the introduction of 50% tetrachloromethane into the rats of the first and second experimental groups, with a dose of 0.25 ml per 100 g of body weight, causes oxidative stress in them which negatively affects the cellular immunity and functional activity of immunocompetent blood cells. Immunosuppressive effects of oxidative stress were manifested by a decrease in the blood of rats in the first and second experimental groups of the number of T- and B-lymphocytes and their regulatory subpopulations mainly on the 2nd and 5th day of the study. At the same time, in the blood of rats of the first experimental group in all research periods a decrease in the relative number of common, active and theophylline-resistant T-lymphocytes, as well as B-lymphocytes was observed with a noticeable increase in the number of their undifferentiated forms. At the same time, the obtained data suggest the positive effect of butafosfan, interferon, thistle and vitamins A, D3, E in the liposomal preparation on the relative amount of T- and B-lymphocytes and on the redistribution of avidity in the direction of strengthening the receptor field of plasma membranes immunocompetent cells. It was found that the normalization on the 2nd day of blood level in the second experimental group of common T-lymphocytes occurred due to the secondary forms of the blood and active T-lymphocytes by changes in the number of low-avid forms. In addition to the indicators characterizing the cellular immunity of rats, the components of the liposomal preparation showed regulatory influence on the humoral link of the immune response. In particular, on the 10th day of research in blood of rats of the second experimental group a tendency towards an increase in the relative number of B-lymphocytes and an increase in the number of cells with low and medium density of receptors was found, which, under the conditions of oxidative stress, indicates an increase in the body's ability to actively synthesize protective antibodies

The paper deals with researching of T- and B-lymphocytes relative quantity and functional activity in broiler chicken blood after using of animal origin immunomodulators in conditions of pre-slaughter stress. The authors determined the relative amount of T- and B-lymphocytes and their individual populations in the reaction of spontaneous rоsetting with the sheep erythrocytes in blood. Besides, the differentiated count of rоsetting lymphocytes with the various degree of functional activity was conducted. The spleen extract (70% alcohol solution in volume of 1.4 ml per chicken) was added to the diet of broiler chicken of experimental groups by aerosol method. This extract was obtained with/ without ultrasound application. 70% alcohol solution in the same volume and using the same method was added to the diet of broiler chicken of the control group five days before slaughter. The authors have not established probable increase of T-lymphocytes general quantity in broiler chicken blood in both experimental groups. It is shown that pre-slaughter stress in broiler chicken caused by weaning has immuno-suppressive effect on T- and B-lymphocytes in blood, which is accompanied by their quantity and functional activity decrease. T- and B-lymphocytes amount and functional activity of T- and B-cell immunity was stimulated after adding immunomodulators of natural origin to broiler chicken diet. Spleen extract polyamines as immunomodulators and antistressors most effectively influenced on some of cell immunity indices before slaughter – it is necessary to note the increase in T-helper lymphocytes in the broiler chickens blood caused by lymphocytes with medium (6–10) – by 18% (Р < 0.05) and high density receptors (М) – by 35% (Р < 0.05) compared to the control. It is shown that decrease of T-lymphocytes quantity in broiler chicken blood is caused by lymphocytes with law (3–5) – by 22% (Р < 0.01) and high (M) – by 11% (Р < 0.05) density receptors with increase of medium density receptors (6–10) – by 15% (Р < 0.05) compared to the control. The results obtained in the experiment can be used in the investigations of cell immunity indices of farm animals in order to increase the organism resistance and to correct their pre-slaughter stress.
