[Cell-mediated immune-phenomenona in hyperthyroidism and euthyroid goiter (studies using the lymphocyte transformation test)].

For the establishment of cellular immune phenomena in hyperthyroidism and the euthyreotic struma 27 patients with hyperthyroidism, 18 patients with euthyreotic struma and 33 healthy control persons were examined with the help of the lymphocyte transformation test as to their ability to the blast cell transformation under addition of watery extract of the thyroid gland. In the cases of hyperthyroidism significantly increased transformation indices were found compared with the controls. Also in the euthyreotic strumae increased values were found compared with the controls. They lay at the borderline to significance. Three different extracts were used as antigen. The transformation indices calculated in these cases were partly significantly different. From this is concluded that not in every watery extract of the thyroid gland the responsible antigen exists in sufficient quantity and/or quality.
