Abstract
The effect of HR-6 solution containing adenosine triphosphate 10 mg/ml on the impaired nasal mucocililary function in 13 patients was studied. The nasal mucociliary function measured with the radioisotopic method using 99Tc-labelled human serum albumin as a tracer substance was markedly impaired in all patients. The patients had had symptoms of upper and/or lower respiratory tract infections for 8 1/2 years, on the average. The nasal mucociliary function ranged from 0 to 5.0 mm/minute, mean 2.0 mm/minute. In this single dose study the test drug improved nasal mucociliary function by at least 1.4 mm/minute in 77% of the patients and by at least 2.8 mm/minute in 54% of the patients. This preliminary study indicates the need for further examinations with the HR-6 in patients with impaired mucociliary function. Key words: Mucociliary function, immotile cilia syndrome.
