Nonspecific Bronchoprovocation Test
Bronchial asthma is a disease characterized by the condition of airway hyper-responsiveness, which serves to produce narrowing of the airway secondary to airway inflammation and/or various spasm-inducing stimulus. Nonspecific bronchoprovocation testing is an important method implemented for the purpose of diagnosing asthma; this test measures the actual degree of airway hyper-responsiveness and...
متن کاملReversible volume changes of trapped gas in nonspecific bronchoprovocation tests.
Thirty patients with a history of asthma and ten patients with suspected bronchial hyperreactivity underwent nonspecific provocation testing. The control group consisted of ten normal volunteers without a history of lung disease. The patients' baseline FEV1 (percent predicted) revealed mild obstructive disease (72.9 +/- 8.9 percent and 74.6 +/- 7.7 percent) compared with controls (87.2 +/- 8.5 ...
متن کاملSputum RNA signature in allergic asthmatics following allergen bronchoprovocation test
BACKGROUND Inhaled allergen challenge is a validated disease model of allergic asthma offering useful pharmacodynamic assessment of pharmacotherapeutic effects in a limited number of subjects. OBJECTIVES To evaluate whether an RNA signature can be identified from induced sputum following an inhaled allergen challenge, whether a RNA signature could be modulated by limited doses of inhaled flut...
متن کاملWhite side test: A simple and rapid test for evaluation of nonspecific bacterial genital infections of repeat breeding cattle

For this purpose, a total of 100 crossbred Jersey cows comprising of 80 repeat breeding animals presented for treatment and 20 normal cyclic (control group) animals presented for artificial insemination at thei...
متن کاملEffect of caffeine on histamine bronchoprovocation in asthma.
It was recently reported that caffeine may reduce the clinical symptoms of asthma and may prevent the clinical manifestations of this disease. The effect of caffeine on histamine responsiveness is unknown. The effect of caffeine (5 mg/kg) and placebo on histamine responsiveness (the provocation concentration causing a 20% fall in FEV1, PC20) was studied in 10 subjects with mild asthma (prechall...
