| IPRL | isolated perfused rat liver or lung |
| KLS | kidneys, liver, and spleen; Kreuzbein lipomatous syndrome |
| LADH | lactic acid dehydrogenase; liver alcohol dehydrogenase |
| liver haemangioendothelioma | <radiology> Females (67%), infants (90% before 6 m/o), symptoms: mass (hepatomegaly), cutaneous haemangiomas (45%), mildly increased aFP (occasionally), with or without congestive heart failure secondary to shunting (only 4%), usually diffuse, precludes surgery, most involute spontaneously or with steroids Differential diagnosis: mesenchymal hamartoma, cavernous haemangioma, hepatoma, hepatoblastoma (increased aFP), metastatic neuroblastoma (increased serum VMA) (12 Dec 1998) |
|---|---|
| liver kidney syndrome | <syndrome> Severe loss of both liver and kidney function, seen in a variety of diseases, often with fatal outcome. Seen particularly in late-stage liver failure due to cirrhosis or hepatitis, and in several viral infections. (05 Mar 2000) |
| liver Lactobacillus casei factor | <biochemistry> Pteridine derivative that is abundant in liver and green plants and is a growth factor for some bacteria. The biochemically active form is tetrahydrofolate (see folate). (12 Nov 1997) |
| liver metastases | <oncology> The spread of cancerous tumours from a distant organ to the liver. Due to the livers tremendous blood and lymphatic supply it is a frequent site for metastatic cancer. Cancers which commonly metastasize to the liver include colon cancer, breast cancer, neuroblastoma, lung cancer and Hodgkin's disease. (14 Oct 1997) |
| liver metastases: ultrasound imaging | <radiology> Echogenic (25%), colonic carcinoma, hepatocellular carcinoma, treated breast carcinoma mixed echogenicity (37.5%), breast carcinoma, rectal carcinoma, lung carcinoma, stomach carcinoma, anaplastic cancer, cervical carcinoma, carcinoid hypoechoic (37.5%), lymphoma, pancreatic carcinoma, cervical carcinoma, lung carcinoma (adenocarcinoma), nasopharyngeal carcinoma see: liver metastases (12 Dec 1998) |
| liver neoplasms, experimental | Experimentally induced tumours of the liver. (12 Dec 1998) |
| liver of sulfur | A mixture composed chiefly of potassium polysulfides and potassium thiosulfate; used externally in scabies, acne, and psoriasis; used in the manufacture of "white lotion". Synonym: liver of sulfur. (05 Mar 2000) |
| liver profile | <investigation> A test that measures the blood serum level of several enzymes produced by the liver. An elevated liver function test is a sign of possible liver damage. Examples include: prothrombin time, PTT, serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, gamma glutamyl transpeptidase, alkaline phosphatase and serum albumin. (14 Oct 1997) |
| liver regeneration | Repair or renewal of hepatic tissue. (12 Dec 1998) |
| liver scan | <investigation> A way of visualising the liver by injecting into the bloodstream a trace dose of a radioactive substance which helps visualize the organ during X-ray. (09 Oct 1997) |
| liver-shod clamp | A clamp with jaws covered by cloth to prevent injury to structures such as bowel when clamp is closed. (05 Mar 2000) |
| liver-spleen scan | <radiology> Tc-99m sulfur colloid or albumin colloid, particles less than 1 m, dose = 4-8 mCi Distribution, liver 85%, spleen 10%, bone marrow 5% Findings, liver: hot / cold, spleen: hot / cold (12 Dec 1998) |
| liver spot | A variably pigmented lentigo occurring on exposed skin of older Caucasians. Synonym: liver spot, solar lentigo. (05 Mar 2000) |
| liver spots | A skin disorder seen with aging (or sun exposure) where there are flat patches of increased pigmentation on the skin. They are nonserious, benign and generally more important cosmetically. The most commonly appear on sun exposed areas such as the forehead and the back of the hands. Avoidance of the sun and the use of a sunscreen (SPF of 15) can reduce the incidence of these lesions. Creams and lotions are available which bleach the skin. Cryotherapy can be used in some cases. (27 Sep 1997) |
| liver starch | <biochemistry> Branched polymer of D glucose (mostly _(1-4) linked, but some _(1-6) at branch points). Size range very variable, up to 10exp5 glucose units. Major short term storage polymer of animal cells and is particularly abundant in the liver and to a lesser extent in muscle. In the electron microscope glycogen has a characteristic asterisk or star appearance. (18 Nov 1997) |
