| vasomotor neurosis | A group of trophic disorders in which pathological changes occur in blood vessels, often due to autonomic nervous system dysfunction; includes Raynaud's disease, acrocyanosis, erythromelalgia, Buerger's disease, causalgia, and trench foot; archaic concept. Synonym: angioneurosis, vasoneurosis. (05 Mar 2000) |

| vasomotor paralysis | A mild degree of vasoparalysis. Synonym: angioparesis, vasomotor paralysis. Origin: vaso-+ G. Paresis, weakness (05 Mar 2000) |
| vasomotor rhinitis | Congestion of nasal mucosa without infection or allergy. (05 Mar 2000) |
| vasomotor spasm | Spasmodic contraction of the smaller arteries. (05 Mar 2000) |
| vasomotor system | The neural systems which act on vascular smooth muscle to control blood vessel diameter. The major neural control is through the sympathetic nervous system. (12 Dec 1998) |
| vasoneuropathy | Any disease involving both the nerves and blood vessels. Origin: vaso-+ G. Neuron, nerve, + pathos, suffering (05 Mar 2000) |
| vasoneurosis | A group of trophic disorders in which pathological changes occur in blood vessels, often due to autonomic nervous system dysfunction; includes Raynaud's disease, acrocyanosis, erythromelalgia, Buerger's disease, causalgia, and trench foot; archaic concept. Synonym: angioneurosis, vasoneurosis. (05 Mar 2000) |
| vasoparalysis | Paralysis, atonia, or hypotonia of blood vessels. Synonym: angiohypotonia, angioparalysis. (05 Mar 2000) |
| vasoparesis | A mild degree of vasoparalysis. Synonym: angioparesis, vasomotor paralysis. Origin: vaso-+ G. Paresis, weakness (05 Mar 2000) |
| vasopressin | <protein> A peptide hormone released from the posterior pituitary lobe but synthesised in the hypothalamus. There are 2 forms, differing only in the amino acid at position 8: arginine vasopressin is widespread, while lysine vasopressin is found in pigs. Has antidiuretic and vasopressor actions. Used in the treatment of diabetes insipidus. (18 Nov 1997) |
| vasopressin level | This test measures the amount of ADH in the serum. It is used to detect disorders that may affect the level of ADH in the serum. Normal values are: 0 to 4.7 pg/ml. Elevated ADH levels can indicate a CNS infection, fluid imbalance, CNS tumour, SIADH or acute porphyria. Low levels can indicate: diabetes insipidus or damage to the pituitary gland. (27 Sep 1997) |
| vasopressin-converting aminopeptidase | <enzyme> Activity found in brain which converts vasopressin into centrally active metabolites Registry number: EC 3.4.11.- Synonym: vp-c aminopeptidase (26 Jun 1999) |
| vasopressin-resistant diabetes | Diabetes insipidus due to inability of the kidney tubules to respond to antidiuretic hormone; X-linked inheritance, with full expression in males and partial defect in heterozygous females. Synonym: vasopressin-resistant diabetes. (05 Mar 2000) |
| vasopressins | <chemical> Octapeptide antidiuretic hormones released by the neurohypophysis of all vertebrates (chemical composition varies with species). They control water metabolism and balance by regulating lung, gill, kidney, etc., and water loss, and also contract smooth muscle. They may also be neurotransmitters. Also included are synthetic vasopressin derivatives. Vasopressins are used pharmacologically as renal agents, vasoconstrictor agents, and haemostatics. Pharmacological action: haemostatics, renal agents, vasoconstrictor agents. (12 Dec 1998) |
| vasopressor | 1. Stimulating contraction of the muscular tissue of the capillaries and arteries. 2. An agent that stimulates contraction of the muscular tissue of the capillaries and arteries. (18 Nov 1997) |
| vasectomy |
a usually permanent method of sterilization in which the tubes carrying sperm from the testicles (the vas deferens) are cut and tied off; as a result, the semen will no longer contain sperm

| vasovagal syncope |
A usually transitory condition that is marked by anxiety, nausea, respiratory distress and fainting, and that is believed to be due to joint vasomotor and vagal disturbances.
