| potassium thiocyanate | Formerly used in the treatment of essential hypertension and as a reagent in the detection of copper, iron, and silver. Synonym: potassium rhodanate, potassium sulfocyanate. (05 Mar 2000) |
|---|---|
| hydrogen-potassium-exchanging atpase | <enzyme> An enzyme isolated from the gastric mucosa that catalyses the hydrolysis of ATP coupled with the exchange of hydrogen and potassium ions across the cell wall. Chemical name: ATP phosphohydrolase (H+/K+-transporting) Registry number: EC 3.6.1.36 (12 Dec 1998) |
| sodium potassium ATPase | <enzyme> A major transport protein of the plasma membrane. A multi unit enzyme, it moves 3 sodium ions out of the cell and 2 potassium ions in, for each ATP hydrolysed. The sodium gradient established is used for several purposes (see facilitated diffusion, action potential), while the potassium gradient is dissipated through the potassium leak channel. Must not be confused with a sodium channel. (18 Nov 1997) |
| sodium-potassium-exchanging atpase | <enzyme> An enzyme that catalyses the active transport system of sodium and potassium ions across the cell wall. Sodium and potassium ions are closely coupled with membrane atpase which undergoes phosphorylation and dephosphorylation, thereby providing energy for transport of these ions against concentration gradients. Chemical name: ATP phosphohydrolase (sodium-potassium-transporting) Registry number: EC 3.6.1.37 (12 Dec 1998) |
| sodium-potassium pump | A membrane-bound transporter that maintains the high potassium and low sodium intracellular concentrations relative to the extracellular medium. This exchange is accomplished at the expense of cellular energy in the form of ATP. (05 Mar 2000) |
| sodium potassium tartrate | KNaC4H4O6;a mild saline cathartic, used as an ingredient in compound effervescent powders. Synonym: Rochelle salt, Seignette's salt, sodium potassium tartrate. (05 Mar 2000) |
| effervescent potassium citrate | A mixture of potassium citrate, citric acid, sodium bicarbonate, and tartaric acid; used as a gastric antacid and urinary alkaliser. (05 Mar 2000) |
| Luft's potassium permanganate fixative | A fixative useful in electron microscopy for cytologic preservation of lipoprotein complexes in membranes and myelin, because of its oxidative properties. (05 Mar 2000) |
| administration, oral | The giving of drugs, chemicals, or other substances by mouth. (12 Dec 1998) |
| cancer, oral | Cancer of the mouth area. A sore in the mouth that does not heal can be a warning sign of oral cancer. A biopsy is the only to know whether as abnormal area in the oral cavity is cancer. Oral cancer is caused by tobacco (smoking and chewing) and alcohol use. Surgery to remove the tumour in the mouth is the usual treatment for patients with oral cancer. (12 Dec 1998) |
| candidiasis, oral | Infection of the mucous membranes of the mouth by a fungus of the genus candida. (12 Dec 1998) |
| canine oral papilloma | Warts affecting mucous membranes of young dogs; caused by a papillomavirus. (05 Mar 2000) |
| magnesia and alumina oral suspension | A mixture of magnesium hydroxide and variable amounts of aluminum oxide; used as an antacid. (05 Mar 2000) |
| pathology, oral | A dental specialty concerned with pathology of the oral cavity. (12 Dec 1998) |
| pharyngo-oral | Relating to the pharynx and the mouth; oropharyngeal. Origin: pharyngo-+ L. Os (or-), mouth (05 Mar 2000) |
