Experiments on animals and clinical observations over patients with infectious-allergic bronchial asthma and rheumatism showed that sodium nucleinate could abolish or suppress the intensity of immediate and delayed type hypersensitivity and the corresponding skin reactions to specific allergens.

The aerosol of aprotinin, a natural low molecular weight polypeptide (m.w. about 160 kD) inhibiting a wide range of serine proteases may be used as an antiviral drug. The animal studies showed that it had no local irritating action on the mucosa. A long-term use of aprotinin in the form of a fine aerosol practically induced no allergenic side effects. The results of the study indicative of the absence of the allergic complications made it possible to recommend the aprotinin inhalations as a safe means in the treatment and prophylaxis of viral infections of the respiratory tract.
The experiments on 18 isolated albino rat hearts have shown that sodium nucleinate exerts a protective action on the occurrence of reperfusion ventricular arrhythmias. Sodium nucleinate was given orally in a daily dose of 50/kg for 2 weeks. The agent reduced the blood concentrations of medium-weight molecular peptides, which may be regarded as the liquidation of a factor predisposing to arrhythmias. Other possible mechanisms responsible for the antiarrhythmic activity of sodium nucleinate, which are adaptable to the immunomodulating and membranoprotective properties of the drug, as well as to its ability to enhance intracellular metabolism are also discussed in the paper.
