N-methylhistamine

05/01/1997 - "Measurement of urinary N-methylhistamine excretion can be used to evaluate the efficacy of agents with antihistaminic action in the treatment of bronchial asthma."
05/01/1997 - "In the patients treated with azelastine, the improvement in clinical symptoms of bronchial asthma correlated significantly with a decrease in urinary N-methylhistamine excretion (r2 = 0.434, P < .001), while no such relationship was noted in patients receiving no antiallergic agent. "
12/01/1998 - "Serum eosinophil cationic protein (ECP), urinary eosinophil protein X (EPX) and urinary N-methylhistamine were investigated in 24 asthmatic children during acute asthma to determine the sequential variation in the parameters. "
12/01/1998 - "[Serum eosinophil cationic protein, urinary eosinophil protein X and urinary N-methylhistamine during acute asthma in children]."

10/01/2003 - "The preponderance of mast cells in the biopsy prompted testing for urine N-methylhistamine levels, which were elevated and confirmed the diagnosis of mastocytosis. "
09/01/2002 - "The likelihood of mastocytosis with mast cell accumulation in the bone marrow biopsy at a given level of N-methylhistamine was calculated. "
09/01/2002 - "Thirty-seven patients with mastocytosis and unexplained elevated levels of urinary N-methylhistamine who were undergoing bone marrow biopsy were studied with respect to the diagnosis of mastocytosis and the manifestations of the disease. "
10/01/1996 - "Value of urinary N-methylhistamine measurements in childhood mastocytosis."
09/01/2005 - "In the present study, we compared results of urinary N-methylhistamine measurements with analysis of total tryptase in serum from patients with suspected mastocytosis. "

09/01/2014 - "Fecal and urinary N-methylhistamine concentrations in dogs with chronic gastrointestinal disease."
09/01/2014 - "The purpose of this study was to measure N-methylhistamine (NMH), a histamine metabolite, in fecal and urine samples from dogs with chronic gastrointestinal disease. "

04/01/2015 - "N-methylhistamine was found to be significantly elevated in gastrointestinal food allergy both during unrestricted diet (7.1, 5.0 - 11.2) and potato-rice diet (5.7, 3.7 - 8.7) compared to controls (p < 0.0001). "
04/01/2003 - "N-methylhistamine in 12-h-urine was significantly increased during both types of diet in patients with collagenous colitis and food allergy when compared with controls (p < 0.001 for all). "
07/01/1994 - "N-methylhistamine (NMH) of the urine histamine metabolite, plasma histamine and eosinophil counts in the blood were determined in fourteen atopic children (aged 5 months-6 years, Mean = 2.8 years, M:F = 7:7) with food hypersensitivities. "

11/01/2000 - "N alpha-Methylhistamine in gastric juice appears therefore to be associated with infection, although this product is not generated directly by the bacterium. "
11/01/2000 - "N alpha-methylhistamine: association with Helicobacter pylori infection in humans and effects on gastric acid secretion."
08/01/1998 - "Inflammatory cytokines, rather than N alpha-methylhistamine, are therefore likely to be responsible for directly inhibiting D-cell function in H pylori infection."
