| Popis: | Objective: In this work, role of the adrenergic nerve system (alpha1 and beta2) in adjustment of the bronchomotor tonus in healthy people was researched. Methods: Parameters of the lung function are determined by Body plethysmography. Raw and ITGV were registered and SRaw was calculated as well. Aerosolization is done with standard aerosolizing machines – Asema. Results: Results gained shows that following the blockade of beta-2 adrenergic receptor with Propranolol (20 mg–aerosol), stimulation of alpha adrenergic receptor with Oxedrine (120 mg-aerosol) and blockage of these receptors with Tolazoline (20 mg-aerosol), does not change significantly the bronchomotor tonus of the tracheobronchial tree (p > 0.1). Meanwhile, stimulation of the beta-2 adrenergic receptor with Hexoprenaline (2 inh x 0.2 mg) is associated with a significant increase of the peripheral resistance of the airways (p < 0.01). Conclusion: This suggests that the activity of the alpha1-adrenergic receptor, unlike the activity of the beta2-adrenergic receptor in the healthy people smooth musculature, is not significant and as such is insufficient to oppose to the tonic activities of the cholinergic system. |
