Urticaria induced by antihistamines.
H1-antihistamines are commonly used drugs, and probably the most frequently used for allergic diseases. They are pharmacologic inverse agonists of histamine at H1 receptor sites and try to shift the equilibrium of this receptor toward the inactive state, preventing H1 response. A wide variety of adverse effects have been attributed to antihistamines, and they can exceptionally induce skin react...
متن کاملModulation of metabolic activity of phagocytes by antihistamines
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...
متن کاملThe role of complement in the modulation by fluid-phase IgG of the production of reactive oxygen species by polymorphonuclear leukocytes stimulated with IgG immune complexes.
The production of reactive oxygen species (ROS) by polymorphonuclear leukocytes (PMN) can be induced by immune complexes and is an important component of phagocytosis in the killing of microorganisms, but can also be involved in inflammatory reactions when immune complexes are deposited in tissues. We have observed that fluid-phase IgG can inhibit the generation of ROS by rabbit PMN stimulated ...
متن کاملModulation of radiation and cadmium induced biochemical changes in mouse kidney by Emblica officinalis Linn
Background: Protective effect of Emblica against radiation and cadmium induced biochemical changes in mouse kidney has been studied. Materials and Methods: Adult male mice were divided into seven groups: I (shamirradiated), II (cadmium chloride), III (irradiated with 2 Gy gamma rays), IV (radiation and cadmium chloride), V (Cadmium chloride and Emblica), VI (radiation and Emblica), VII...
متن کاملReceptors for Complement on Leukocytes
Sheep red blood cells sensitized by 7S, but not by 19S rabbit anti-Forssman antibodies, adhere and form rosettes on mouse macrophages and on a few monocytes and polymorphonuclear cells (PMN). When, however, C' factors from mouse serum are added to the antigen-19S antibody complex (EAC'), rosettes are formed on most mouse peritoneal macrophages and PMN and on a few monocytes. In addition EAC' al...
