The activity of arylsulphatases in serum of patients with several bullous diseases.

Spectrophotometric estimations of levels of activities of arylsulphatases A and B in serum of patients with several bullous diseases were carried out. The activities of these enzymes in cases of bullous pemphigoid were at high levels in comparison with those in cases of other bullous diseases and in the control group. Especially, the activity of arylsulphatase B was remarkably increased. It seems likely that there is some relationship between these disturbances and the pathogenesis of bullous pemphigoid.
