[Determination of antithrombin III in situ in the skin of patients with allergic arteriolitis].

The authors assessed antithrombin III in patients with allergic arteriolitis. Positive expression of antithrombin was assessed on endothelia, thrombi and infiltrate cells in approximately 2/3 of patients of the examined group (n = 23). The authors assume that expression of antithrombin III reflects inhibited hemocoagulation in the affected vessels as well as inhibition of leucocyte proteases in the above disease.
