INTRODUCTION: Mast cells have been implicated in the aetiology of many diseases and are particularly important in evoking leukocyte-endothelial interactions during endotoxemia. Mast cell activity can be modified by histamine. There are only little data available whether serotonin (5-HT), another amine, is involved in alterations of mast cell activity, too.(More)
By means of the proof for the enzyme phenol oxidase (PO; EC 1.14.18.1) was investigated, whether the eosinophilic granuloma correspond to a cell mediated immunological defence reaction. The method allowed to determine the eosinophils rapidly and surely and give an overview on the frequency and distribution of these cells. By electron microscopy was(More)
An eosinophilic granuloma has been investigated by means of histochemical proofs for enzymes and tissue elements and common staining methods. The best method was be found the proof for the enzyme phenol oxidase (EC 1.14.18.1). In this way it is possible to determine eosinophils rapidly and surely and to receive an overview on the frequency and distribution(More)
