OBJECTIVES We evaluated the effect of external nasal dilator strips and local decongestants used either alone or in combination on the nasal airway. SUBJECTS AND METHODS The study included 23 volunteer males (mean age 24.3 years; range 21 to 36 years) with no complaints of nasal obstruction. Nasal airway dimensions were measured by acoustic rhinometry after the following applications: (i) no ...

Hypertension has been linked to an impaired dilator function of the coronary microvascular endothelium in vivo. However, the profile and mechanism of this dysfunction remain obscure. Thus, this study compared diameter responses to acetylcholine (ACH), bradykinin (BKN), and substance P (SP) between coronary microvessels (i.d.=106+/-4 microm) dissected from left ventricles of normotensive and hyp...

The innervation of the extrinsic uterine arterial supply of the guinea pig has been studied using an isolated perfused preparation. The preparation was normally at minimal tone and responded to periarterial stimulation by a vasoconstriction which was mimicked by norepinephrine and abolished by bretylium. Constrictor responses both to stimulation and to norepinephrine were similar in both pregna...

Background: The ineffectiveness of hemodialysis fistulas causes high costs and increases mortality and morbidity rates. The efficacy of drug-coated balloon and nondrug-coated balloon in dysfunctional arteriovenous Fistula was evaluated over six month period. Methods: In this randomized clinical trial, a total of a total of 50 hemodialysis patients who referred to Imam Reza Hospital in Kermansh...
