title: [Mercury contact dermatitis].
abstract: Eight female patients with contact allergy to Mercury were studied with the L. T. T. and the Histamine degranulation test of basophiles. In the eight cases the L. T. T. was specific. P. H. A. (an inspecific lymphocyte stimulator lectin) and the Histamine degranulation basophile test, were used as controls. Thirty subjects were used as controls. All of them were negative to the patch test with mercury at 0,5% in petrolatum. No atopic antecedents were among them and their families. No once case of lymphocyte activity to mercury was observed. Mercury acetate solutions at: 12,5 ng/ml. 25 ng/ml and 5 ng/ml were employed. This salt was the unique useful for the L. T. T. practice. Extremely difficulties for the solubilization of mercury bichloride, mercury oxide, phenyl mercury and ammoniated mercury, impaired the L. T. T. with these salts.
