|---|---|
| lymphatic plexus | A plexus of lymphatic capillaries, usually without valves, that opens into one or more larger lymphatic vessels. Synonym: plexus lymphaticus. (05 Mar 2000) |
| lymphatic ring of cardiac part of stomach | A group of lymph nodes surrounding the cardia of the stomach. Synonym: annulus lymphaticus cardiae, cardiac lymphatic ring. (05 Mar 2000) |
| lymphatic sarcoma | <tumour> Obsolete term for lymphosarcoma. (05 Mar 2000) |
| lymphatic sinus | The channels in a lymph node crossed by a reticulum of cells and fibres and bounded by littoral cells; there are subcapsular, trabecular, and medullary sinus's. Synonym: lymph sinus. Maier's sinus, an infundibuliform depression on the internal surface of the lacrimal sac which receives the lacrimal canaliculi. Marginal sinuses of placenta, discontinuous venous lakes at the margin of the placenta. (05 Mar 2000) |
| lymphatic stroma | The network of reticular fibres and associated reticular cells of lymphatic tissue. (05 Mar 2000) |
| lymphatic system | <anatomy> The tissues and organs (including the bone marrow, spleen, thymus and lymph nodes) that produce and store cells that fight infection and the network of vessels that carry lymph. (12 May 1997) |
| lymphatic tissue | A structure found within the lymphatic system that consists of lymphocytes within a network of fibres. (09 Oct 1997) |
| lymphatic valvule | One of the delicate semilunar valves found in lymphatic vessels; they are usually paired and similar in structure to venous valves and occur at close intervals along the vessel wall. Synonym: valvula lymphatica. (05 Mar 2000) |
| lymphatic vessel | <anatomy> Vessels that remove cellular waste from the body by filtering through lymph nodes and eventually emptying into the blood system. They are similar to blood vessels but transport lymph fluid. (14 Oct 1997) |
| lymphatic vessels | The vessels that convey the lymph; they anastomose freely with each other. Synonym: vasa lymphatica, absorbent vessels, lymphatic vessels, lymphatics. (05 Mar 2000) |
| lymphatic vessel tumours | Neoplasms composed of lymphoid tissue, a lattice work of reticular tissue the interspaces of which contain lymphocytes. The concept does not refer to neoplasms located in lymphatic vessels. (12 Dec 1998) |
| ambulant oedema | Oedema forming during periods of walking with the legs dependent. (05 Mar 2000) |
| angioneurotic oedema | <neurology> An acute or recurring attack of transient oedema suddenly appearing in areas of the skin or mucous membranes and occasionally of the viscera, often associated with dermatographism, urticaria, erythema, and purpura. It can produce dramatic swelling of the subcutaneous tissues (welts beneath the skin) that typically appears around the eyes and lips. Welts may also involve the hands, feet and throat (compromise the airway). This condition is associated with allergies (for example foods, pollen), but may also be a side effect of some medications (for example ACE inhibitors, salicylates). Emotional stress, exposure to cold, water, sunlight, heat and insect bites all have been know to cause angioneurotic oedema. Treatment is with adrenaline, antihistamines, cimetidine, and/or corticosteroids. (12 Dec 1998) |
| angioneurotic oedema, hereditary | A genetic form of angioedema. (Angioedema is also referred to as Quinke's disease.) Persons with it are born lacking an inhibitor protein (called C1 esterase inhibitor) that normally prevents activation of a cascade of proteins leading to the swelling of angioedema. Patients can develop recurrent attacks of swollen tissues, pain in the abdomen, and swelling of the voice box (larynx) which can compromise breathing. The diagnosis is suspected with a history of recurrent angioedema. It is confirmed by finding abnormally low levels of C1 esterase inhibitor in the blood. Treatment options include antihistamines and male steroids (androgens) that can also prevent the recurrent attacks. Also called hereditary angioedema. (12 Dec 1998) |
