Ventilation distribution during histamine provocation.
We investigated ventilation inhomogeneity during provocation with inhaled histamine in 20 asymptomatic nonsmoking subjects. We used N2 multiple-breath washout (MBW) to derive parameters Scond and Sacin as a measurement of ventilation inhomogeneity in conductive and acinar zones of the lungs, respectively. A 20% decrease of forced expiratory volume in 1 s (FEV1) was used to distinguish responder...
متن کاملRelationship between histamine and physiological changes during the early response to nasal antigen provocation.
To investigate the temporal relationships of mediator release and physiological changes during the early response to allergen, we challenged allergic individuals intranasally with antigen and followed their responses. This was done by using small filter paper disks to challenge one nostril and collect secretions from both the challenged and the contralateral nostril, thus enabling us to evaluat...
متن کاملHistamine intolerance-like symptoms in healthy volunteers after oral provocation with liquid histamine.
Histamine in food at non-toxic doses has been proposed to be a major cause of food intolerance causing symptoms like diarrhea, hypotension, headache, pruritus and flush ("histamine intolerance"). Histamine-rich foods such as cheese, sausages, sauerkraut, tuna, tomatoes, and alcoholic beverages may contain histamine up to 500 mg/kg. We conducted a randomized, double-blind, placebo-controlled cro...
متن کاملShunt and ventilation-perfusion distribution during partial liquid ventilation in healthy piglets.
Replacing gas in the lung with perfluorocarbon fluids (PFC) and periodically ventilating with a gas [partial liquid ventilation (PLV)] has been shown to improve oxygenation in models of respiratory distress syndrome. We hypothesized that the addition of PFC to healthy lungs would result in shunt, diffusion impairment, and increased ventilation-perfusion (VA/Q) heterogeneity. Previously, Mates e...
متن کاملFacial flushing during provocation in women.
Facial flushing was studied in 38 young women who scored high or low on trait anger. To induce anger in the subjects, their task was to solve a difficult puzzle, with or without harassment from a female research assistant. Facial blood flow increased in response to provocation, together with increases in cardiovascular and electrodermal activity. Flushing was associated with large increases in ...
