Using voltage-clamp technique, the involvement of epoxygenases in immunomodulatory drug glutoxim regulation of Na+ transport in frog skin was investigated. We have shown for the first time that preincubation of the frog skin with epoxygenase inhibitors econazole or proadifen almost completely inhibits the stimulatory effect of glutoxim on Na+ transport. The data suggest the involvement of the enzymes and/or products of epoxygenase oxidation pathway of arachidonic acid metabolism in glutoxim effect on Na+ transport in frog skin epithelium.

UI	MeSH Term	Description	Entries
D009842	Oligopeptides	Peptides composed of between two and twelve amino acids.	Oligopeptide
D010088	Oxidoreductases	The class of all enzymes catalyzing oxidoreduction reactions. The substrate that is oxidized is regarded as a hydrogen donor. The systematic name is based on donor:acceptor oxidoreductase. The recommended name will be dehydrogenase, wherever this is possible; as an alternative, reductase can be used. Oxidase is only used in cases where O2 is the acceptor. (Enzyme Nomenclature, 1992, p9)	Dehydrogenases,Oxidases,Oxidoreductase,Reductases,Dehydrogenase,Oxidase,Reductase

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D017136	Ion Transport	The movement of ions across energy-transducing cell membranes. Transport can be active, passive or facilitated. Ions may travel by themselves (uniport), or as a group of two or more ions in the same (symport) or opposite (antiport) directions.
