Effect of cyclodextrin on allergic action of the PiCl-induced in NC/Nga mice

Itching dermatitis, which is very similar to human atopic dermatitis, arises spontaneously in NC/Nga mice. Changes in lesional skin and the plasma concentration of IgE during the development of atopic dermatitis-like disease up to 8 weeks after the start of picryl chloride (PiCl) in NC/Nga mice were examined. In the mice which atopic dermatitis had been induced, 28-day administration of α cyclodextrin (α CD) significantly inhibited aggravation of detmatitis without having effects on body weight. Clinical signs and symptoms seen in PiCl treated NC/Nga mice began with erythema and haemorrhage, following oedema, superficial erosion, deep excoriation, scaling and dryness of the skin. An increase was observed in the number of mast cells and eosinophil infiltration in the lesional skin. Almost human patients with nasal inflammation or bronchial asthmatics symptoms disappeared by oral administration of α CD (5 mg/day) for 2 month. These results suggest that α CD is useful for treatment of human atopic dermatitis.     

Isolated points and essential components of composition operators on

We consider the topological space of all composition operators on the Banach algebra of bounded analytic functions on the unit disk. We obtain a function theoretic characterization of isolated points and show that each isolated composition operator is essentially isolated.

     

Observing quantum correlation of photons in Laguerre-Gauss modes using the Gouy phase

The effect of the Gouy phase, which is one of the geometrical phases of photons, is observed through quantum correlation in Laguerre-Gaussian (LG) modes. In an experiment, the relative phase of two different LG modes of measurement basis states is manipulated via the Gouy phase, and the observed coincidence count rates agree well with theoretical predictions. This result suggests that the Gouy phase can be used as a new tool to manipulate multidimensional photonic quantum states.
