[An evaluation of the allergizing properties of merthiolate as a component of adsorbed DTP vaccine].

The study of the allergenic properties of thimerosal contained in adsorbed DPT vaccine was carried out. Two variants of this vaccine, with and without thimerosal, as well as thimerosal alone (diluted 1:10,000, which corresponds to the content of this preservative in the vaccine), were used in experiments. The phenomenon of anaphylactic shock, passive dermal anaphylaxis and skin tests were used as test-systems.

[Differential diagnosis and treatment of metatypic cancer].

Fifty one patients with metatypic carcinoma (MC), 10 with basalioma, and 10 with squamous cell carcinoma were clinically and immuno-morphologically studied. There were great differences in the localization of basal cell antigen in the epidermis during MC, basalioma, squamous carcinoma of the skin. Expression of fixed immunoglobulins A, M, G in tumor tissues revealed no significant differences.

[The use of Russian allergoids for the specific immunotherapy of pollinosis].

For three years 128 pollinosis patients received specific immunotherapy with cereals, weed and tree pollen allergens manufactured by the Scientific and Industrial Amalgamation "Allergen" (Stavropol). For comparison, a group of 42 patients was treated with the corresponding allergens according to the commonly used treatment scheme. Patients who had earlier undergone treatment with water-saline extracts of allergens, that proved to be ineffective, formed a special group.

[A comparative immunochemical analysis of allergoids and allergens].

In comparison with allergens having protein fragments with a molecular weight not exceeding 110 kD, allergoids have been found to consist of larger fragments with a molecular weight of 10-150 kD. Allergoids have less charged components than initial allergens and less antigenic components. Allergoids retain their capacity for stimulating the production of antibodies, specific to all antigenic components.

[The comparative characteristics of different forms of allergens from mites of the genus Dermatophagoides].

The comparative study of allergenic preparations of Dermatophagoides mites [correction of ticks] from different manufacturers and the international standard preparations of such allergens was made. D. pteronyssinus and D.
