| stomach cell types | <radiology> Parietal (oxyntic), in fundus and body, may lead to HCl (acid) and intrinsic factor, chief, in fundus and body, may lead to pepsinogen, G-cells, in antrum, mucus? (12 Dec 1998) |
| oesophageal carcinoma: types | <radiology> Histologic types: squamous cell carcinoma (95%), adenocarcinoma (4%), 70% from Barrett oesophagus, carcinosarcoma = pseudosarcoma = spindle cell squamous cell carcinoma, usually middle 1/3 of oesophagus, large, polypoid, smooth, intramural mass; may be pedunculated, mucoepidermoid carcinoma, adenoid cystic carcinoma radiologic types: polypoid/fungating form (most common), sessile/pedunculated tumour with lobulated surface, applecore lesion, ulcerating form, infiltrating form, gradual narrowing with smooth transition (Differential diagnosis: benign stricture), varicoid form: superficial spreading carcinoma, thickened nodular tortuous longitudinal folds (Differential diagnosis: varices) (12 Dec 1998) |
| test types | Letters of various sizes used to test visual acuity. (05 Mar 2000) |
| Jaeger's test types | Type of different sizes used for testing the acuity of near vision. (05 Mar 2000) |
| antitoxin | <protein> A purified antiserum from animals (usually horses) immunised by injections of a toxin or toxoid, administered as a passive immunising agent to neutralise a specific bacterial toxin, for example, botulinus, tetanus or diphtheria. (18 Nov 1997) |
| antitoxin rash | A cutaneous manifestation of serum sickness. Astacoid rash, a massive exfoliation, sometimes occurring in malignant smallpox, the colour of which resembles that of a boiled lobster. Black currant rash, the cutaneous eruption of lentigines seen in xeroderma pigmentosum. (05 Mar 2000) |
| antitoxin unit | A unit expressing the strength or activity of an antitoxin; in general, determined with reference to a preserved standard preparation of antitoxin. See: L doses. (05 Mar 2000) |
| bivalent gas gangrene antitoxin | Antitoxin specific for the toxins of Clostridium perfringens and C. Septicum. (05 Mar 2000) |
