To evaluate the use of topical cyclosporine A (CsA) 1% emulsion in the treatment of chronic ocular surface inflammation (OSI).We conducted a retrospective chart review of patients with various forms of OSI treated with topical CsA 1% from 2001 to 2012.Twenty-...

Histamine suppresses regulatory T cells mediated by TGF-β in murine chronic allergic contact dermatitis.

Exp. Dermatol. 24(4) , 280-4, (2015)

Regulatory T cells (Tregs) suppress effector T cells and ameliorate contact hypersensitivity (CH); however, the role of Tregs in chronic allergic contact dermatitis (CACD) has not been assessed. Repeated elicitation of CH has been used to produce CACD models ...

The purpose of this study was to develop and validate an ultra-performance liquid chromatography method for simultaneous analysis of 20 antihistamines (illegal additives) in dietary supplements. The limits of detection and quantitation of the method ranged fr...

Expression of Mas-related gene X2 on mast cells is upregulated in the skin of patients with severe chronic urticaria.

J. Allergy Clin. Immunol. 134(3) , 622-633.e9, (2014)

Wheal reactions to intradermally injected neuropeptides, such as substance P (SP) and vasoactive intestinal peptide, are significantly larger and longer lasting in patients with chronic urticaria (CU) than in nonatopic control (NC) subjects. Mas-related gene ...

The effect of antihistamines on seizures induced by increasing-current electroshocks: ketotifen, but not olopatadine, promotes the seizures in infant rats.

Biol. Pharm. Bull. 35(5) , 693-7, (2012)

Clinical reports have shown that some antihistamines, such as ketotifen, occasionally produced seizures, especially in pre-school age children or young patients with epilepsy. The purpose of this study was to investigate whether olopatadine, one of the most e...
