1 Histaminase (EC-1.4.3.6), one of the two catabolic enzymes for histamine, is contained in human granulocytes. Histamine amine oxidase copper containing 1 Homo sapiens
2 Opsonized zymosan or the calcium ionophore A-23187 induce a dose-dependent release of histaminase from human granulocytes in vitro. Zymosan amine oxidase copper containing 1 Homo sapiens
3 Opsonized zymosan or the calcium ionophore A-23187 induce a dose-dependent release of histaminase from human granulocytes in vitro. Calcium amine oxidase copper containing 1 Homo sapiens
4 Opsonized zymosan-induced histaminase release was maximal in the presence of both calcium and magnesium, whereas ionophore release was magnesium independent. Zymosan amine oxidase copper containing 1 Homo sapiens
5 Opsonized zymosan-induced histaminase release was maximal in the presence of both calcium and magnesium, whereas ionophore release was magnesium independent. Calcium amine oxidase copper containing 1 Homo sapiens
6 Opsonized zymosan-induced histaminase release was maximal in the presence of both calcium and magnesium, whereas ionophore release was magnesium independent. Magnesium amine oxidase copper containing 1 Homo sapiens
7 The total cellular content of histaminase could be released by both opsonized zymosan and ionophore. Zymosan amine oxidase copper containing 1 Homo sapiens
8 Zymosan- and ionophore-induced histaminase release was inhibited by agents that are presumed to interfere with cell metabolism and disrupt microtubules. Zymosan amine oxidase copper containing 1 Homo sapiens
9 Human granulocytes therefore may modulate the effect of histamine by releasing histaminase at a site of inflammation. Histamine amine oxidase copper containing 1 Homo sapiens
