Gold-induced reduction in reactivity to histamine in isolated guinea pig tracheal rings. 1983

S Suzuki, and N Yamauchi, and T Miyamoto, and M Muranaka

Direct effects of gold preparations on the smooth muscle were investigated on isolated guinea pig tracheal rings. Pretreatment of the tracheal rings for 150 min with 100 microM of gold sodium thiomalate [Au(I)] significantly reduced the contraction heights induced by 4.5 microM histamine from 0.24 +/- 0.02 to 0.14 +/- 0.01 g (p less than 0.01). Gold chloride [Au(III)] was far more potent in its inhibitory effects than gold sodium thiomalate. With 15 min preincubation, gold chloride significantly suppressed the histamine-induced contraction (p less than 0.05) at such a low concentration as 10 microM (3.4 micrograms/ml). Gold chloride as well as gold sodium thiomalate did not interfere with the ciliary motion of the tracheal epithelium, whereas colchicine, having no effect on the histamine-induced contraction, did interfere with ciliary motion. These results reveal that gold itself inhibits noncaustically the guinea pig tracheal contraction induced by histamine.

D009119	Muscle Contraction	A process leading to shortening and/or development of tension in muscle tissue. Muscle contraction occurs by a sliding filament mechanism whereby actin filaments slide inward among the myosin filaments.

D009130	Muscle, Smooth	Unstriated and unstriped muscle, one of the muscles of the internal organs, blood vessels, hair follicles, etc. Contractile elements are elongated, usually spindle-shaped cells with centrally located nuclei. Smooth muscle fibers are bound together into sheets or bundles by reticular fibers and frequently elastic nets are also abundant.

D002923	Cilia	Populations of thin, motile processes found covering the surface of ciliates (CILIOPHORA) or the free surface of the cells making up ciliated EPITHELIUM. Each cilium arises from a basic granule in the superficial layer of CYTOPLASM. The movement of cilia propels ciliates through the liquid in which they live. The movement of cilia on a ciliated epithelium serves to propel a surface layer of mucus or fluid.

D006046	Gold	A yellow metallic element with the atomic symbol Au, atomic number 79, and atomic weight 197. It is used in jewelry, goldplating of other metals, as currency, and in dental restoration. Many of its clinical applications, such as ANTIRHEUMATIC AGENTS, are in the form of its salts.
D006052	Gold Sodium Thiomalate	A variable mixture of the mono- and disodium salts of gold thiomalic acid used mainly for its anti-inflammatory action in the treatment of rheumatoid arthritis. It is most effective in active progressive rheumatoid arthritis and of little or no value in the presence of extensive deformities or in the treatment of other forms of arthritis.

D006632	Histamine	An amine derived by enzymatic decarboxylation of HISTIDINE. It is a powerful stimulant of gastric secretion, a constrictor of bronchial smooth muscle, a vasodilator, and also a centrally acting neurotransmitter.	Ceplene,Histamine Dihydrochloride,Histamine Hydrochloride,Peremin
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement.
