| Mallory bodies | Large, poorly defined accumulations of eosinophilic material in the cytoplasm of damaged hepatic cells in certain forms of cirrhosis and marked fatty change especially due to alcoholism. Synonym: alcoholic hyalin, alcoholic hyaline bodies. (05 Mar 2000) |
|---|---|
| Mallory's aniline blue stain | <technique> A method especially suitable for studying connective tissue; sections are stained in acid fuchsin, aniline blue-orange G solution, and phosphotungstic acid; fibrils of collagen are blue, fibroglia, neuroglia, and muscle fibres are red, and fibrils of elastin are pink or yellow. Synonym: Mallory's aniline blue stain, Mallory's triple stain. (05 Mar 2000) |
| Mallory's collagen stain | <technique> One of a number of staining methods using phosphomolybdic or phosphotungstic acid with an acid stain, such as aniline blue, or with haematoxylin for connective tissue staining. (05 Mar 2000) |
| Mallory's iodine stain | <technique> Amyloid appears red-brown after Gram's iodine, then violet and blue after flooding with dilute sulfuric acid. (05 Mar 2000) |
| Mallory's phloxine stain | <technique> A technique based on retention of phloxine by hyaline after overstaining and then decolorizing with lithium carbonate, used in combination with alum haematoxylin to give nuclear staining; hyaline appears red, older hyaline is pink to colourless, amyloid is pale pink, and nuclei are blue-black. (05 Mar 2000) |
| Mallory's phosphotungstic acid haematoxylin stain | A stain with broad application in cytology and histology; nuclei, mitochrondria, fibrin, neuroglial fibrils, and cross-striations of skeletal and cardiac muscle stain blue; cartilage ground substance, bone reticulum, and elastin appear in shades of yellow-orange and brownish red; also useful for demonstrating abnormal or diseased astrocytes, often in combination with periodic acid-Schiff stain and Luxol fast blue. Synonym: Mallory's phosphotungstic acid haematoxylin stain. (05 Mar 2000) |
| Mallory's stain | <technique> For actinomyces, a stain using alum haematoxylin, followed by eosin; immersion in Ehrlich's aniline crystal violet stain, and Weigert's iodine solution; mycelia stain blue and clubs stain red. For haemofuchsin, sections are stained sequentially in alum haematoxylin and basic fuchsin; the lipofuchsin-like pigment and ceroid stain bright red, nuclei stain blue, while melanin and haemosiderin appear unstained in their natural browns.

| Mallory's trichrome stain | <technique> A method especially suitable for studying connective tissue; sections are stained in acid fuchsin, aniline blue-orange G solution, and phosphotungstic acid; fibrils of collagen are blue, fibroglia, neuroglia, and muscle fibres are red, and fibrils of elastin are pink or yellow. Synonym: Mallory's aniline blue stain, Mallory's triple stain. (05 Mar 2000) |

| Mallory-Weiss lesion | Laceration of the gastric cardia, as seen in the Mallory-Weiss syndrome. Synonym: Mallory-Weiss tear. (05 Mar 2000) |
| mallory-weiss syndrome | <syndrome> Mucosal gastric tear, only 10% are purely oesophageal: most are at GE junction or proximal stomach, M greater than F, associated with retching, EtOH, massive haematemesis, abdominal pain, Diagnosis: endoscopy, Treatment: IA vasopressin see: oesophageal trauma (12 Dec 1998) |
| mallory-weiss tear | Lacerations in the oesophageal mucosa that occur close to ot at the junction of the oesophagus and the stomach. Mallory-Weiss tears occur as the result of forceful vomiting or coughing. Symptoms include vomiting blood. (27 Sep 1997) |
