Leukocyte (white blood cell)
|
|
Leukocyte (white blood cell)Cells in the blood that seeks and destroys disease-causing microorganisms.
RELATED TERMS--------------------------------------
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--------------------------------------
Leukemia
Cancer of white blood cells. Acute leukemias are characterized by the presence of "blasts," which are immature white blood cells. Large quantities of blasts generally overgrow the bone marrow, leaving very little space for normal bone marrow cells. This type generally requires immediate treatment. Chronic leukemias are those characterized by a large and uncontrolled growth of more mature white blood cells. These types of leukemias tend not to progress as rapidly, and treatment is often milder than that of acute leukemias.
Leukemoid
Like leukemia.
Leukeran
Leukeran 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): chlorambucil.
Leukine
Leukine 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): sargramostim.
Leukocyte
White blood cell.
Leukocyte infiltration
Leukocyte infiltration refers to the process of moving or infiltrating of the leukocytes into the injured tissue to begin the repair process.
Leukocytes
White blood cells, the blood cells responsible for fighting infection.
Leukoencephalitis
Inflammation of the white matter of the brain.
Leukopenia
Reduction in the number of leukocytes in the blood.
Leukoplakia
Thick, white patches in the mouth that may become malignant.
Leukorrhea
White discharge.

LASERS
Recently high intensity light (lasers) has been developed for use in the dental field. Dental lasers allow for an easier and cleaner way to cut soft tissue and recently have been improved to enable the dentist to cut hard tissue (enamel) as well. The lasers used in dentistry come in three different variations. The greatest difference is in the laser beam and the depth of cut and temperature at the surface of the cut being made by the laser. The two most common types of soft tissue lasers are the CO2 laser and the YAG laser. The CO2 cuts more on the surface and does not raise the temperature very high on the surface to be treated which allows the tissue a better response to healing. The YAG laser will cut deeper and at a higher temperature so it can overheat some of the underlying structures below the tissue surface. The third type of laser is the newly developed laser for cutting hard tissue (enamel) called the erbium laser. An attribute of the erbium laser is that it does not overheat the tooth so that the tooth pulp (nerve) will not die. The erbium laser is currently being utilized in a small number of dental practices in the United States but may be more generally available in the near future.
Lead Extraction
A lead is a special wire that delivers energy from a pacemaker or implantable cardioverter defibrillator (ICD) to the heart muscle.A lead extraction is the removal of one or more leads from inside the heart. Leads that are placed outside the heart during open heart surgery cannot be removed during this type of procedure.
Leaflets
Thin pieces of tissue or flaps that make up a valve.
Left Ventricular Assist Device (LVAD)
In patients with end-stage heart disease whose hearts do not pump a sufficient amount of blood to keep the body healthy, it is possible to place a mechanical device that aids in the pumping function of the blood. This device is known as a left ventricular assist device. There are many devices available for implantation.
Legal Guardian
A person charged (usually by court appointment) with the power and duty of taking care of and managing the property and rights of another person who is unable to take care of their own affairs.
Leukocyte (white blood cell)
Life-Sustaining Treatment
A medical treatment given to a patient that prolongs life and delays death.
Linolenic Acid (Omega 3)
An essential fatty acid. Omega3, which is found in fish and certain plants, may reduce the risk of cardiovascular disease and myocardial infarction by lowering triglyceride levels and blood pressure and preventing the formation of life-threatening thrombi.
Living Will
A written advance directive in which an individual states which health care decisions should be made if the individual becomes unable to make these decisions.
Long QT Syndrome (LQTS)
LQTS is a disorder of the heart’s electrical system. LQTS is a defect in the ion channels, causing a delay in the time it takes for the electrical system to recharge after each heartbeat. When the QT interval is longer than normal, it increases the risk for torsade de pointes, a life-threatening form of ventricular tachycardia.
Low Density Lipoprotein (LDL)
A lipoprotein particle in the blood responsible for depositing cholesterol into the lining of the artery. Known as "bad" cholesterol because high LDL is linked to coronary artery disease.
