The purpose of the study was to investigate the effects of H(1)-antihistamines of the 1(st) generation (antazoline, bromadryl, brompheniramine, dithiaden, cyclizine, chlorcyclizine, chlorpheniramine, clemastine) and the 2(nd) generation (acrivastine, ketotifen, and loratadine) on the respiratory burst of phagocytes. Reactive oxygen species generation in neutrophils isolated from rat blood was m...
We investigated the role of mast cells in granuloma-associated angiogenesis in rat by using: (i) a mast cell membrane stabilizer, ketotifen; (ii) a mast cell depleting agent, compound 48/80. Moreover, we focused on the role of chymases, which exhibit proinflammatory and pro-angiogenic properties by using: (i) chymostatin, an inhibitor of chymase activity; (ii) a specific antisense oligonucleoti...
Passive cutaneous anaphylaxis (PCA) reaction elicited in ears of male ddY mice was studied by means of assessing dye leakage. In the ear, PCA reaction was more sensitive and reproducible than that in the dorsal skin. The reaction was significantly suppressed by ketotifen, one of antianaphylactic agents.

Vertebrate eyes are known to contain circadian clocks, but their regulatory mechanisms remain largely unknown. To address this, we used a cell line from human retinal pigment epithelium (hRPE-YC) with stable coexpression of reporters for molecular clock oscillations (Bmal1-luciferase) and intracellular Ca2+ concentrations (YC3.6). We observed concentration-dependent increases in cytosolic Ca2+ ...
The antiallergic activity of betotastine besilate was evaluated in comparison to that of other compounds in various rat models of allergy. Betotastine besilate inhibited histamine release from rat peritoneal mast cells and inhibited LTB4 and 5-HETE production in peritoneal cells at high concentrations (1 mM). Following oral administration at doses ranging from 0.1-30 mg/kg p.o., betotastine inh...
