The lowest concentrations of citric acid were measured that caused coughing in 10 normal subjects who inhaled successively higher concentrations. Two subjects did not cough at any concentration. In the remaining eight the threshold concentration was significantly higher when measured in the afternoon than it was in the morning (p less than 0.05). The expected diurnal variation in peak expirator...

After two hours of abstinence from smoking pulmonary functions were assessed in twenty-seven asymptomatic male smokers by spirometry and Wright Peak Flow Meter, recording FVC, FEV1, FEV1%, FEF25-75%, and FEF75-85% of FVC, MVV and PEFR. These tests were repeated immediately after smoking and again after one hr. Only PEFR decreased significantly (P less than 0.01) and returned to nearly basal lev...
