There has been significant utilization of the technique described by Hamelmann et al. (Am J Respir Crit Care Med 156: 766-775, 1997) in which a parameter, enhanced pause (Penh), related to airways responsiveness is noninvasively measured by unrestrained plethysmography (UP). Investigating this technique, we sought to answer these questions: 1). How do(More)
Unrestrained plethysmography and airway responsiveness 2/29 Abstract There has been significant utilization of the technique described by Hamelmann et al. (1997) in which a parameter, Penh, related to airways responsiveness is non-invasively measured using unrestrained plethysmography (UP). We investigated this technique, seeking to answer these questions:(More)
Bronchial hyperresponsiveness is the characteristic feature of bronchial asthma. Inhalation of allergen can cause dual asthmatic response--early and late reaction. Thirteen patients with mild and moderate asthma underwent bronchial allergen challenge. Non-specific bronchial reactivity was measured before, 90 minutes, on the 2nd, 7th, 14th day after(More)
The aim of this study was to evaluate the effect of loratadine on allergen-induced bronchoconstriction. The study was performed in 7 asthmatic patients with sensitivity to Dermatophagoides pteronyssinus, 4 women and 3 men. aged from 19 to 37 years. The allergen inhalatory--challenge test was performed according to Chai et al. Early phase of Dermatophagoides(More)
In the previous few years, there has been a startling escalation in intraoperative and radiologic anaphylactic episodes, some of them lethal, that have been assigned to rubber exposure. Immediate hypersensitivity reactions to natural rubber pose a significant risk to patient with spina bifida and urogenital abnormalities, health care workers, and rubber(More)
The aim of this study was to assess the duration of Loratadine effect on histamine H1 receptor in the airway. Six patients with mild or moderate asthma were examined. Bronchial reactivity to histamine was measured according to Cockcroft. The significant blockade of histamine H1 receptors in airway was observed from the 2nd day when 10 mg of Lo was given(More)
The influence of single and repeated LO (10 mg/day) doses on histamine-induced bronchoconstriction was studied in 11 patients with stabile bronchial asthma. Bronchial reactivity was estimated as histamine content potent to elicit a 20% FEV, fall, i.e. PC20H. A single dose gave a significant (5.5 fold) reduction in bronchial reactivity to inhaled histamine.(More)
The study was performed in 11 patients suffering from stable mild and moderate atopic asthma. Bronchial allergen challenges were performed according to Chai et al method. Airway hyperreactivity-AH (PC20H in mg/ml) was determined in each study day before subthreshold allergen inhalation dose, meaning the dose which did not induce asthmatic responses. Then(More)
Phagocytic index and rosette test E have been determined in 50 patients, including 15 with diffuse peritonitis and the noncomplicated diffuse peritonitis, 20 patients with septic complications, and 15 patients who underwent abdominal surgery. It was found, that phagocytic index is decreased in all patients after abdominal surgery. The most marked decrease(More)
The study was performed in 19 patients with stable mild/moderate asthma aged from 16 to 66. Nonspecific airway hyperresponsiveness (AH) to histamine was measured according to Cockcroft's et al. method and expresses as PC20H in mg/ml. The study was controlled by inhalation of PBS. The histamine or PBS challenges were performed three times at 45 min.(More)
