Vasoconstrictor Agents
|
D014662 |
[Drugs used to cause constriction of the blood vessels.

|
Vasodilation
|
D014664 |
[The physiological widening of BLOOD VESSELS by relaxing the underlying VASCULAR SMOOTH MUSCLE.
, VASODILATION that is mediated via the ENDOTHELIUM-DEPENDENT RELAXING FACTORS or their processes.

|
Vasodilator Agents
|
D014665 |
[Drugs used to cause dilation of the blood vessels.
] |
|
Vasomotor System
|
D014666 |
[The neural systems which act on VASCULAR SMOOTH MUSCLE to control blood vessel diameter. The major neural control is through the sympathetic nervous system.

|
Vasopeptidase Inhibitors
|
D000075563 |
[A class of cardiovascular drugs indicated for hypertension and congestive heart failure that simultaneously inhibit both NEUTRAL ENDOPEPTIDASE and ANGIOTENSIN CONVERTING ENZYME. They increase the availability of NATRIURETIC PEPTIDES and BRADYKININ and inhibit production of ANGIOTENSIN II.

|
Vasoplegia
|
D056987 |
[Condition of low SYSTEMIC VASCULAR RESISTANCE that develops secondary to other conditions such as ANAPHYLAXIS; SEPSIS; SURGICAL SHOCK; and SEPTIC SHOCK. Vasoplegia that develops during or post surgery (e.g., CARDIOPULMONARY BYPASS) is called postoperative vasoplegic syndrome or vasoplegic syndrome.

|
Vasopressins
|
D014667 |
[Antidiuretic hormones released by the NEUROHYPOPHYSIS of all vertebrates (structure varies with species) to regulate water balance and OSMOLARITY. In general, vasopressin is a nonapeptide consisting of a six-amino-acid ring with a cysteine 1 to cysteine 6 disulfide bridge or an octapeptide containing a CYSTINE. All mammals have arginine vasopressin except the pig with a lysine at position 8. Vasopressin, a vasoconstrictor, acts on the KIDNEY COLLECTING DUCTS to increase water reabsorption, increase blood volume and blood pressure.
, A pharmaceutical preparation containing a mixture of arg-vasopressin and lys-vasopressin. It is prepared by synthesis or obtained from neurohypophyseal extract of domestic animals. Its vasopressor activity is not less than 300 USP vasopressin units per mg.

|
Vasospasm, Intracranial
|
D020301 |
[Constriction of arteries in the SKULL due to sudden, sharp, and often persistent smooth muscle contraction in blood vessels. Intracranial vasospasm results in reduced vessel lumen caliber, restricted blood flow to the brain, and BRAIN ISCHEMIA that may lead to hypoxic-ischemic brain injury (HYPOXIA-ISCHEMIA, BRAIN).

|
Vasotocin
|
D014668 |
[A nonapeptide that contains the ring of OXYTOCIN and the side chain of ARG-VASOPRESSIN with the latter determining the specific recognition of hormone receptors. Vasotocin is the non-mammalian vasopressin-like hormone or antidiuretic hormone regulating water and salt metabolism.

Vasovasostomy
|
D014669 |
[Surgical anastomosis or fistulization of the spermatic ducts to restore fertility in a previously vasectomized male.
] |
|
Vatican City
|
D014671 |
[Enclave of Rome.

|
Vault Ribonucleoprotein Particles
|
D020394 |
[Large cytoplasmic ribonucleoprotein particles that have an eight-fold symmetry with a central pore and petal-like structure giving the appearance of an octagonal dome. (The Dictionary of Cell Biology, Lackie and Dow, 2nd ed.)

Vector Borne Diseases
|
D000079426 |
[Infectious diseases transmitted by DISEASE VECTORS.
] |
|
Vectorcardiography
|
D014672 |
[Recording of the moment-to-moment electromotive forces of the heart on a plane of the body surface delineated as a vector function of time.
] |
|
Vecuronium Bromide
|
D014673 |
[Monoquaternary homolog of PANCURONIUM. A non-depolarizing neuromuscular blocking agent with shorter duration of action than pancuronium. Its lack of significant cardiovascular effects and lack of dependence on good kidney function for elimination as well as its short duration of action and easy reversibility provide advantages over, or alternatives to, other established neuromuscular blocking agents.

|
Vegans
|
D000066989 |
[Persons who avoid consuming animal products or animal-derived substances, such as MEAT; EGGS; or HONEY. Some vegans also refrain from using animals or animal products in any form or for any purpose, such as in CLOTHING or household goods.

|
D000067075 |
[Food that is manufactured from various parts of vegetables.

Vegetables
|
D014675 |
[A food group comprised of EDIBLE PLANTS or their parts.

|
Vegetarians
|
D000066988 |
[Persons who adopt a VEGETARIAN DIET that includes both EGGS and DAIRY PRODUCTS, but no MEAT.
, Persons who do not eat MEAT.

Vehicle Emissions
|
D001335 |
[Gases, fumes, vapors, and ODORANTS escaping from the cylinders of a gasoline or diesel internal-combustion engine. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed & Random House Unabridged Dictionary, 2d ed)
