| liver diseases, parasitic | Infections of the liver with a parasite. They are caused most commonly by trematodes (flukes). (12 Dec 1998) |
|---|---|
| liver enzyme | <biochemistry> Special proteins found in the cells of the liver that are responsible for catalysing specific metabolic reactions. They may become elevated in the bloodstream in conditions of hepatitis or liver cancer. See: liver function tests. (27 Sep 1997) |
| liver extracts | <chemical> Extracts of liver tissue containing uncharacterised specific factors with specific activities; a soluble thermostable fraction of mammalian liver is used in the treatment of pernicious anaemia. Pharmacological action: haematinics. (12 Dec 1998) |
| liver failure | A condition of severe end-stage liver dysfunction that is accompanied by a decline in mental status that may range from confusion (hepatic encephalopathy) to unresponsiveness (hepatic coma). Other features include a mousy odour to the breath, difficulty with balance and walking, tremor and impaired speech. (27 Sep 1997) |
| liver failure, acute | A form of liver failure with rapid onset. It is often induced by the toxic effect of drugs and various toxic substances in experimental studies in animals and in clinical states in humans. If coma ensues, the constellation of neurological symptoms is referred to as hepatic encephalopathy. (12 Dec 1998) |
| liver filtrate factor | Former term for pantothenic acid. (05 Mar 2000) |
| liver flap | <clinical sign, neurology> Abnormal muscle tremor consisting of involuntary jerking of the hands. May be seen in liver disease. (27 Sep 1997) |
| liver function test | <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 glycogen | Glycogen stored in the liver. (12 Dec 1998) |
| 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) |
