[Signs of microbial sensibilization in patients with various cardiovascular diseases].

Aim: Analysis of intensity of non-specific (level of sera cytokines) and specific (titers of antibodies against Chlamydophila pneumoniae) factors of humoral immunity in patients with arterial hypertension and various forms of ischemic heart diseases.

Materials And Methods: 282 individuals were the object of examination--157 (55.7%) males.

[Mechanisms of the effect of exogenous thyroxine on the regulation of the immune response in mice].

The influence of repeated administration of thyroxin (T4) in doses of 4 or 4000 micrograms/100 g body weight daily upon T-B co-operation and specific T-suppressor formation was studied on CBA male rats. A stimulating effect of T4 low doses on the lymph node T-cell ability was demonstrated to co-operate with the normal marrow B-cells over a process of generation of the humoral response to the sheep red blood cells within the system of singeneic transfer. The injection of various T4 doses to donors of the marrow B-lymphocytes or recipients of T- and B-cells from control animals did not alter the immune response in recipients.
