Using an improved static and dynamic light-scattering technique, we have observed multiscale relaxation of the pretransitional fluctuations in the isotropic phase of a cromolyn aqueous solution, a lyotropic liquid crystal where rods are formed by aggregates of disklike molecules. We have detected the onset of cromolyn aggregation about 12 degrees C above the transition temperature. The onset is...

We have investigated whether the inspiratory flow at which sodium cromoglycate (SCG) is inhaled influences the efficacy of SCG. Seven atopic asthmatic subjects (age 25 +/- 2 yrs) inhaled dry powder SCG from a Spinhaler on separate occasions at three flow rates, maximum (V1), 100 l.min-1 (V2), and 50 l.min-1 (V3), or placebo, according to a double-blind structured study. Thirty minutes after adm...

The causes of asthma remain unknown although it is now clear that the underlying pathology of the disease, even in its mildest forms, is one of chronic persistent inflammation. This fact is recognised in many national, and more recently, international guidelines, which recommend that treatment in all but the most mild episodic asthma should be aimed at the underlying pathology rather than at su...

PURPOSE We report the efficacy of an alternative method of treatment for vernal keratoconjunctivitis (VKC) that consists of excision of the palpebral conjunctiva followed by supratarsal injection of corticosteroid and five times daily topical application of 0.05% cyclosporine A (CsA) and cromolyn sodium. METHODS We evaluated 10 patients with severe treat-resistant VKC with corneal complicatio...
