The effect of sodium nucleinate on allergic and immunological reactions.
Experiments on immunized rabbits and guinea pigs indicated that sodium nucleinate (SN) was capable of weakening or entirely eliminating anaphylactic and skin reactions of delayed type hypersensitivity to repeated administration of staphyloanatoxin, APDT vaccine. The findings on patients with the infectious form of bronchial asthma and chronic rheumatism showed that sodium nucleinate attenuated reactions to the subcutaneous administration of staphylococcal and streptococcal allergens. The treatment of patients suffering from infectious-allergic bronchial asthma and rheumatism with SN resulted in the recovery of deficient T cells, T-suppressors, normalization of immunoglobulin concentrations. In children with acute glomerulonephritis sodium nucleinate normalized decreased T-suppressor cells and increased IgG and circulating immune complexes (CIC), resulting in a pronounced remission of disease. The mechanism of desensitization and elimination of CIC by SN has not been explored, however, the parameters of SN-induced immunomodulation are known rather completely. It is suggested that SN brings about accumulation in the cell of cyclic AMP which diminished membrane permeability, activates monoaminooxidase resulting in the degradation of histamine and other biogenic amines, enhances the synthesis of endogenous corticosteroids with their desensitizing properties. All these effects contribute to the elimination of delayed type hypersensitivity. The role of SN in the inhibition of delayed type hypersensitivity remains obscure.
