| ulceromembranous gingivitis | An acute or recurrent gingivitis of young and middle-aged adults characterised clinically by gingival erythema and pain, fetid odour, and necrosis and sloughing of interdental papillae and marginal gingiva which gives rise to a gray pseudomembrane; fever, regional lymphadenopathy, and other systemic manifestations also may be present. A fusiform bacillus and Treponema vincentii can be isolated from the gingival tissues in large numbers and are felt to play a significant but poorly defined role in the pathogenesis. Synonym: fusospirochetal gingivitis, trench mouth, ulceromembranous gingivitis, Vincent's disease, Vincent's infection. (05 Mar 2000) |

| leukaemic hyperplastic gingivitis | Enlarged gingiva due to infiltration of leukaemic cells and infection from local factors in the face of diminshed host response. (05 Mar 2000) |
| glomerulonephritis, membranous | A disease of the glomerulus manifested clinically by proteinuria, and sometimes by other features of the nephrotic syndrome. It is histologically characterised by deposits in the glomerular capillary wall between the epithelial cell and the basement membrane and a thickening of the membrane. Also characteristic are outward projections of the membrane between the epithelial deposits in the form of "spikes". There is some agreement that the deposits are antigen-antibody complexes.

| membranous | Having a thin, soft, pliable texture. (09 Oct 1997) |
| membranous ampulla | A nearly spherical enlargement of one end of each of the three saemicircular ducts, anterior, posterior, and lateral, where they connect with the utricle. Each contains a neuroepithelial crista ampullaris. Synonym: ampulla membranacea, membranous ampulla. (05 Mar 2000) |
| membranous cataract | A secondary cataract composed of the remains of the thickened capsule and degenerated lens fibres. (05 Mar 2000) |
| membranous cochlea | Spiral tube in the bony canal of the cochlea, lying on its outer wall between the scala vestibuli and scala tympani. (12 Dec 1998) |
| membranous conjunctivitis | A severe conjunctival inflammation caused by Corynebacterium diphtheriae and characterised by an infiltrating membrane which on removal leaves a raw surface. Synonym: membranous conjunctivitis. (05 Mar 2000) |
| membranous dysmenorrhoea | Dysmenorrhoea accompanied by an exfoliation of the menstrual decidua. (05 Mar 2000) |
| membranous glomerulonephritis | <pathology> A kidney disease that occurs due to inflammation of the kidney glomerulus and its basement membrane. The exact cause is unknown but it appears to be related to the deposition of immune complexes in the basement membrane leading to thickening of the capillary walls. This disorder is a common cause of nephrotic syndrome an is usually how the disease manifests. Risk factors include primary renal disease, malaria, hepatitis B, lupus, syphilis, cancers and non-Hodgkin's lymphomas. Risks also include exposure to some medications such as gold compounds and penicillamine. Mercury, trimethadione and some skin-lightening creams have also been implicated. Treatment includes systemic corticosteroids and immunosuppressive agents. (26 Mar 1998) |
| membranous labyrinth | A complex arrangement of communicating membranous canaliculi and sacs, filled with endolymph and surrounded by perilymph, suspended within the cavity of the bony labyrinth; its chief divisions are the cochlear labyrinth and the vestibular labyrinth. Synonym: labyrinthus membranaceus. (05 Mar 2000) |
| membranous lamina of cartilaginous auditory tube | The connective tissue membrane that, with the lateral lamina, completes the lateral and inferior walls of the cartilaginous part of the auditory tube. Synonym: lamina membranacea cartilaginis tubae auditivae, membranous layer. (05 Mar 2000) |
| membranous laryngitis | A form in which there is a pseudomembranous exudate on the vocal cords. (05 Mar 2000) |
| membranous layer | The connective tissue membrane that, with the lateral lamina, completes the lateral and inferior walls of the cartilaginous part of the auditory tube. Synonym: lamina membranacea cartilaginis tubae auditivae, membranous layer. (05 Mar 2000) |
