Histamine 103-112 histidine decarboxylase Rattus norvegicus 53-56 1729265-5 1992 These increases in HDC activity, and mucosal and lymph histamine levels were suppressed by pretreatment of alpha-fluoromethylhistidine (alpha-FMH), a suicide inhibitor of HDC. Histamine 55-64 histidine decarboxylase Rattus norvegicus 171-174 1414511-5 1992 As demonstrated in experiments with an inhibitor of histidine decarboxylase--semicarbazide, this effect comprised 15% inhibition evoked by the histamine precursor--histidine, whereas the remaining 60% inhibition could be ascribed to the effect of newly synthesized histamine. Histamine 143-152 histidine decarboxylase Rattus norvegicus 52-75 1414511-5 1992 As demonstrated in experiments with an inhibitor of histidine decarboxylase--semicarbazide, this effect comprised 15% inhibition evoked by the histamine precursor--histidine, whereas the remaining 60% inhibition could be ascribed to the effect of newly synthesized histamine.

Histamine 173-182 histidine decarboxylase Rattus norvegicus 27-50 2377078-5 1990 The elevation in HDC activity in these tissues probably accounts for the increase in tissue and plasma concentrations of histamine in diabetic animals, since there is no change in histamine catabolism.

Histamine 111-120 histidine decarboxylase Rattus norvegicus 195-218 894608-4 1977 Kinetic analysis of enzyme-catalysed histidine decarboxylation in extracts from untreated vagotomized and from histamine-treated vagotomized rats showed that the histamine-induced suppression of histidine decarboxylase activity probably reflects a reduced enzyme concentration. Histamine 162-171 histidine decarboxylase Rattus norvegicus 195-218 894608-6 1977 These observations suggest that administration of histamine not only inhibits enzyme synthesis but also causes an accelerated rate of elimination of histidine decarboxylase.3. Histamine 50-59 histidine decarboxylase Rattus norvegicus 149-172 856608-6 1977 Results suggest that the increased level of serum histamine is the consequence of the increased activity of histidine decarboxylase in the tissues and a rapid elimination of the newly formed histamine into the blood.

Histamine 93-102 histidine decarboxylase Rattus norvegicus 4-27 185510-3 1976 It has been found that pentagastrin induces histidine decarboxylase in gastric mucosa, ensuring local accumulation of histamine. Histamine 118-127 histidine decarboxylase Rattus norvegicus 44-67 185510-8 1976 The findings raise the possibility that histamine and 3",5"-AMP, mediating gastrin action, form together with enzymes (histidine decarboxylase, adenylate cyclase, protein kinase, carbonic anhydrase) a caascade of amplifiers. Histamine 40-49 histidine decarboxylase Rattus norvegicus 119-142 5573952-1 1971 Histamine content of rat brain was lowered quickly by inhibitors of histidine decarboxylase, suggesting that a portion of brain histamine turns over rapidly.
