Vasculitis
|
|
Vasculitis Inflammation throughout the body of the blood vessels.
RELATED TERMS--------------------------------------
Inflammation
A reaction to an injury to the body - by infection, chemicals or physical agents. The symptoms can be - depending on the location of the injury- redness, swelling, heat and pain. The purpose of the inflammation is to dilute and destroy the agent causing the inflammation. To do this, the immune system starts a cascade of actions that causes active cells to gather at the affected location. It is these cells and fluids that cause the redness, swelling, heat and pain.
Blood
The life-maintaining fluid which is made up of plasma, red blood cells (erythrocytes), white blood cells (leukocytes), and platelets; blood circulates through the body's heart, arteries, veins, and capillaries; it carries away waste matter and carbon dioxide, and brings nourishment, electrolytes, hormones, vitamins, antibodies, heat, and oxygen to the tissues.
SIMILAR TERMS--------------------------------------
Vascor
Vascor is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): bepridil hydrochloride.
Vascoray
Vascoray is a prescription or over-the-counter drug which is (or once was) approved in the United States and possibly in other countries. Active ingredient(s): iothalamate meglumine; iothalamate sodium.
Vascular
Pertaining to blood vessels.
Vascularity
The blood supply of a tumor.
PREVIOUS AND NEXT TERMS--------------------------------------
Ventromedial Nucleus (VMN)
The part of the hypothalamus sensitive to excess glucose.
Virus
Ultramicroscopic infectious agent that replicates itself only within cells of living hosts; many are pathogenic; a piece of nucleic acid (DNA or RNA) wrapped in a thin coat of protein.
Varicella
Also known as chickenpox is a mild, highly contagious disease characterised by fever and itchy blisters all over the body. It is caused by the varicella zoster virus. It is very common in children but can affect people of all ages.
Valdecoxib
Valdecoxib is a prescription drug used in the treatment of osteoarthritis, rheumatoid arthritis, and painful menstruation and menstrual symptoms. It is classified as a nonsteroidal anti-inflammatory drug, or NSAID, and should not be taken by anyone allergic to these types of medications.
Venlafaxine hydrochloride
An inhibitor of serotonin and norepinephrine reuptake, unrelated chemically to any other antidepressants, that potentiates neurotransmitter activity in the central nervous system, used as an antidepressant.
Vasculitis
Vitiligo
An autoimmune skin disorder caused by attack of the immune system on the pigment-producing cells within the skin. The loss of the cells responsible for skin color result in milky white patches on the skin surface.
Varicose Veins
Varicose veins -swollen, purple veins- are common in the legs and around the vaginal opening during late pregnancy. In most cases, varicose veins are caused by the increased pressure on the legs and the pelvic veins, and by the increased blood volume.
Vasopressin
Hormone secreted by the posterior pituitary gland (trade name Pitressin) and also by nerve endings in the hypothalamus; affects blood pressure by stimulating capillary muscles and reduces urine flow by affecting reabsorption of water by kidney tubules.
Vasoconstriction
A reduction in the diameter of small arteries (arterioles) which is caused by constriction of the smooth muscle fibres in the wall of the arteriole. Vasoconstriction is an important method of increasing the blood pressure. In local areas of damage it prevents blood loss by haemostasis. Local vasoconstriction can be caused by nerve impulses to the smooth muscle from the sympathetic nervous system, by locally released prostaglandins, serotonin and Epinephrine.
