[Early diagnosis and effective prevention of occupational allergies caused by hexavalent chromium].

Clinical and allergologic evaluation covered a large group of workers engaged into alumina production and exposed to chromate. Those workers were also subjected to long-standing follow-up. The studies helped to find correlation of chromium concentration in air with occurrence of the occupational allergies and latent sensibilization of respiratory tract to chromium. Immune modulator Levamisol was proved to act as a desensibilizer in prophylaxis of the occupational allergies in individuals with the latent sensibilization.
