| mucoenteritis | 1. Inflammation of the intestinal mucous membrane. Synonym: mucomembranous enteritis. (05 Mar 2000) |
|---|---|
| mucoepidermoid | Denoting a mixture of mucus-secreting and epithelial cells, as in mucoepidermoid carcinoma. (05 Mar 2000) |
| mucoepidermoid carcinoma | <tumour> Most commonly a salivary gland carcinoma of low grade malignancy in children, but with variable malignancy in adults; composed of mucous, epidermoid, and intermediate cells, with mucous cells abundant only in low grade carcinoma's; recurrence is frequent, and high grade carcinoma's metastasize to cervical nodes. Synonym: mucoepidermoid tumour. (05 Mar 2000) |
| mucoepidermoid tumour | A malignant epithelial tumour of glandular tissue, especially the salivary glands, characterised by acini with mucus-producing cells and by the presence of malignant squamous elements. most mucoepidermoid tumours are low-grade lesions readily cured by adequate excision. They may appear in any age group. They grow slowly. If high-grade, they behave aggressively, widely infiltrating the salivary gland and producing lymph node and distant metastases. (12 Dec 1998) |
| mucoepithelial dysplasia | An epithelial cell dishesive disease characterised by red, periorificial mucosal lesions of oral, nasal, vaginal, urethral, anal, bladder, and conjunctival mucosa, with cataracts, follicular keratosis, non-scarring alopecia, frequent pulmonary infections, pneumothorax, and sometimes cor pulmonale; autosomal dominant inheritance. (05 Mar 2000) |
| mucoglobulin | A glycoprotein or mucoprotein in which the protein component is a globulin. (05 Mar 2000) |
| mucoid | Resembling mucus. (27 Sep 1997) |
| mucoid adenocarcinoma | <tumour> Sometimes applied to mucinous carcinoma, or adenocarcinoma containing mucin secreting neoplastic cells. (05 Mar 2000) |
| mucoid colony | A colony showing viscous or sticky growth typical of an organism producing large quantities of a carbohydrate capsule. (05 Mar 2000) |
| mucoid degeneration | A conversion of any of the connective tissues into a gelatinous or mucoid substance. Synonym: myxoid degeneration, myxomatous degeneration, myxomatosis. (05 Mar 2000) |
| mucoid impaction of bronchus | Plugging of the lumen of bronchi due to thickened mucus, interfering with ventilation of corresponding lung segments and leading to characteristic clustered linear and grape-like radiologic densities and occasionally atelectasis and pneumonia; characteristically seen in cystic fibrosis but it can occur in a variety of disease states. (05 Mar 2000) |
| mucoid medial degeneration | Loss of elastic and muscle fibres in the aortic media, with accumulation of mucopolysaccharide, sometimes in cystlike spaces between the fibres; a disease of unknown cause, which may be inherited and which predisposes to dissecting aneurysms. Synonym: Erdheim disease, medionecrosis aortae idiopathica cystica, medionecrosis of the aorta, mucoid medial degeneration. (05 Mar 2000) |
| mucolipidosis | <biochemistry> A group of inherited metabolic diseases characterised by the accumulation of excessive amounts of acid mucopolysaccharides, sphingolipids, and/or glycolipids in visceral and mesenchymal cells. Abnormal amounts of sphingolipids or glycolipids are present in neural tissue. Mental retardation and skeletal changes are common. (12 Dec 1998) |
| mucolipidosis I | <biochemistry> Mucolipidosis somewhat like a mild form of Hurler's syndrome with mild dysostosis multiplex, and moderate mental retardation due to neuraminidase deficiency. Inheritance: autosomal recessive. Synonym: lipomucopolysaccharidosis. (05 Mar 2000) |
| mucolipidosis II | <biochemistry> Mucolipidosis of early onset and with severe symptoms like those in Hurler's syndrome but with normal urinary mucopolysaccharides, vacuolated lymphocytes, and inclusion bodies in cultured fibroblasts (I-cells). The lysosomes lack hydrolases but high concentrations of lysosomal enzymes are found in the extracellular fluids such as serum, spinal fluid, and urine. It is associated with a deficiency of N-acetylglucosaminyl-1-phosphotransferase. The gene defect responsible probably prevents the addition of the lysosome recognition marker mannose 6 phosphate) to these enzymes so that they are not directed into the lysosomes but are released. Inheritance: autosomal recessive. Synonym: I-cell disease, inclusion cell disease. (12 Jul 2000) |
