In rats and guinea-pigs both mast cell damage and histamine release in anaphylaxis were inhibited by pyridine, nicotinamide, diethylnicotinamide, nicotinic acid, isonicotinic acid and isonicotinic acid hydrazide, which are known to be inhibitors of diphosphopyridine nucleotidases. On the other hand these compounds potentiated histamine release and mast cell damage by compound 48/80 in guinea-pigs although inhibiting the same phenomena in rats. The relationship of these findings with the mechanism of histamine liberation in anaphylaxis is discussed.
已知吡啶、烟酰胺、二乙烟酰胺、烟酸、异烟酸和异烟肼是二磷酸吡啶核苷酸酶的抑制剂,它们可抑制大鼠和豚鼠过敏反应中的肥大细胞损伤和组胺释放。另一方面,这些化合物增强了豚鼠因化合物48/80引起的组胺释放和肥大细胞损伤,尽管在大鼠中抑制了相同的现象。本文讨论了这些发现与过敏反应中组胺释放机制的关系。
