Efficiency of hypertonic and isotonic seawater solutions in chronic rhinosinusitis.

Background: To compare the efficiency of isotonic and hypertonic seawater solutions used for nasal lavage and quality of life of the patients with chronic rhinosinusitis.

Methods: A random and controlled clinical study was performed. The study included 60 patients with history of chronic rhinosinusitis.

Influence of nasal fontanel receptors on the regulation of tracheobronchal vagal tone.

Aim: To test the hypothesis according that the receptors located in the nasal fontanels influence the regulation of the tracheobronchial tree vagus tone.

Methods: Changes in respiratory parameters (forced expiratory volume in the first second- FEV1 and total resistance- Rt) occurring consequentially to light mechanical nasal stimulation were determined in healthy volunteer, non-smokers using spirometric and body plethysmographic measurements. The parameters were measured before and at 15 and 60 min after mechanical stimulation with cotton pledge.
