OBJECTIVE To investigate the dynamics of the synchronization between heart rate variability and sleep electroencephalogram power spectra and the effect of sleep apnea-hypopnea syndrome. METHODS Heart rate and sleep electroencephalogram signals were recorded in controls and patients with sleep apnea-hypopnea syndrome that were matched for age, gender,(More)
The purpose of this placebo-controlled, double-blind, randomized study was to assess the effect of nebulized morphine on dyspnoea perceived at rest by patients with advanced disease. Seventeen hospital in-patients with disabling dyspnoea received isotonic saline or morphine via nebulization for 10 min through a mouthpiece, combined with oxygen via nasal(More)
BACKGROUND Continuous positive airway pressure (CPAP) treatment improves the risk of cardiovascular events in patients suffering from severe sleep apnea-hypopnea syndrome (SAHS) but its effect on the link between delta power band that is related to deep sleep and the relative cardiac vagal component of heart rate variability, HF(nu) of HRV, is unknown.(More)
Ether lipid analogues of platelet-activating factor (1-octadecyl-2-acetyl-sn-glycero-3-phosphocholine) possess a wide range of biological activities, including inhibition of neoplastic cell growth in vitro and in vivo. This activity is believed to be membrane mediated. Three different ether lipid analogues, 1-octadecyl-2-methyl-rac-glycero-3-phosphocholine,(More)
The purpose of this study, in patients with chronic obstructive pulmonary disease (COPD), was to examine the relationship of dyspnoea, rated on a visual analogue scale (VAS), to 1) tidal ventilatory variables measured on exercise and 2) pre-exercise lung function. Twenty one patients (forced expiratory volume in one second (FEV1) mean (SD) 1.19 (0.32) l)(More)
The purpose of this study was to assess the perception of bronchodilation, as a change in shortness of breath on a bipolar visual analogue scale (VAS), in 16 asthmatics and 20 subjects with COPD. Bronchodilation was gradually induced by five consecutive terbutaline inhalations (cumulated dose 800 micrograms). The subjects were categorized into high and low(More)
It is accepted today that all patients with acute asthma should be treated with a sympathomimetic, irrespective of previous therapy. This short review addresses the question of the optimal mode of administration of these drugs in acute severe asthma. Inhaled sympathomimetics are as effective as subcutaneous adrenaline, or intravenous salbutamol or(More)
The rote of prostaglandin endoperoxide synthetase in thÃïn vìvo activation of benzo(a)py rene to reactive metabolites capable of interacting irreversibly with cellular macromolecules was stud ied in guinea pig liver, lung, kidney, spleen, small intestine, colon, and brain. DNA and protein covalent binding experiments were made after systemic administration(More)
