| spirochetotic | Relating to or marked by spirochetosis. (05 Mar 2000) |
| spirogram | The tracing made by the spirograph. (05 Mar 2000) |
| spirograph | <physiology> An instrument for recording the respiratory movements, as the sphygmograph does those of the pulse. Origin: L. Spirare to breathe + -graph. Source: Websters Dictionary (01 Mar 1998) |
| spirometer | An instrument for measuring the vital capacity of the lungs, or the volume of air which can be expelled from the chest after the deepest possible inspiration. Cf. Pneumatometer. Origin: L. Spirare to breathe. Source: Websters Dictionary (01 Mar 1998) |
| spirometra | A genus of tapeworms of the family diphyllobothriidae, which are parasites of fish-eating cats, dogs, and birds. Infection in man is caused by eating undercooked fish. The larval form is called sparganum. (12 Dec 1998) |
| Spirometra mansoni | A species of pseudophyllid tapeworms of wild and feral cats, the larval form of which (sparganum) may survive in human tissues; it has been commonly found in humans in the Orient, but is also reported from widely scattered areas elsewhere; infection of humans with the sparganum occurs from active migration of the larva from freshly split infected frogs used as a poultice for wounds, sore eyes (as in ocular sparganosis>), bruises, or ulcerations; it is also likely that humans may be infected with sparganum larvae from eating any vertebrate harboring these plerocercoids. Synonym: Diphyllobothrium linguloides, Diphyllobothrium mansoni. (05 Mar 2000) |
| Spirometra mansonoides | A species of pseudophyllid tapeworms from North America, whose larva (sparganum) may be a cause of sparganosis of man in Florida and the Gulf States. Synonym: Diphyllobothrium mansonoides. (05 Mar 2000) |
| spirometry | Measurement of volume of air inhaled or exhaled by the lung. (12 Dec 1998) |
| spironolactone | <drug> Aldosterone antagonist: diuretic, used to treat low renin hypertension and Conn's syndrome (in which there is overproduction of aldesterone). (18 Nov 1997) |
| spironolactone test | Administration of spironolactone (400 mg orally) for 4 consecutive days: an increase in serum potassium during the test, and a decrease afterward, strongly suggest primary aldosteronism. (05 Mar 2000) |
| spiroplasma | Gram-negative organisms isolated from the leaves of citrus plants affected by "stubborn" disease. (12 Dec 1998) |
| spiroplasmataceae | A family of bacteria consisting of helical cells that require sterols for growth. (12 Dec 1998) |
| spiroscope | <instrument, physiology> A wet meter used to determine the breathing capacity of the lungs. Origin: L. Spirare to breathe + -scope. Source: Websters Dictionary (01 Mar 1998) |
