pemphigoid gestationis/peroxidase

IgG and C3 deposits were observed in the basement membrane zone in a case with herpes gestationis. In addition, circulating IgG anti-basement membrane antibodies were found. Electron microscopic immunocytochemical investigations, performed with a peroxidase-antiperoxidase sandwich technique,

Eleven patients with the clinical picture of herpes gestationis were investigated. Biopsies were taken from involved and uninvolved areas of skin and the immunopathological and microscopic changes studied. Direct immunofluorescence showed a deposition of C3 and/or IgG at the basement membrane zone

Five patients with typical bullous herpes gestationis and five patients with polymorphic eruption of pregnancy were studied. Shave biopsies were taken from both involved and uninvolved skin and examined by routine immunofluorescence. They were also examined by immunoelectron microscopy employing a

Ultrastructural localization of C3 deposition in the skin of two patients with herpes gestationis was determined by using a peroxidase-antiperoxidase multistep technique. The tissue preparations can be stored for long periods of time and identical sections may be used for light and electron
