Titlesort descending Definition
T Lymphocytes / T Cell A type of lymphocyte that matures in the thymus gland and contributes to the cell-mediated immune response. These cells circulate between the blood and lymph nodes. There are three types of T cells: cytotoxic (killer), helper, and suppressor.
Tetanus An acute, often fatal, disease that is characterized by the spasmodic contraction of voluntary muscles, especially those of the neck and jaw. It is caused by the toxin of the bacillus <em>Clostridium tetani</em> which typically infects the body through a deep wound. It is also called lockjaw.
Tetanus Immune Globulin Immune globulin from human blood for use in treating persons not previously immunized against tetanus whose wound would indicate the need for tetanus prophylaxis. Human Tetanus Immune Globulin will produce fewer side effects than will tetanus antitoxin produced from horse serum.
Thrombin An enzyme that participates in blood clotting by converting fibrinogen to fibrin.
Thrombocytopenia A decreased number of blood platelets, cells that are important for clotting.
Thromboplastin Blood coagulation Factor III. This blood protein accelerates the clotting of blood by converting prothrombin into thrombin (in the presence of calcium ions). It is also called platelet tissue factor and thrombokinase.
Titer The concentration of a substance in solution, used as a measure of strength. More specifically, it refers to the concentration of antibodies against a specific antigen in the blood.
Total Parenteral Nutrition (TPN) Nutrition maintained entirely by the administration of a nutritionally adequate solution through a catheter into a vena cava or by some other non gastrointestinal route. Used in cases of long-term comas or burns, or severe gastrointestinal syndromes.
