| vinblastine | <drug, oncology> Alkaloid (818D) isolated from Vinca (periwinkle): binds to tubulin heterodimer and induces formation of paracrystals rather than tubules. Net result is that microtubules disappear as they disassemble and are not replaced. Used in tumour chemotherapy. (18 Nov 1997) |
| vinblastine sulfate | A dimeric alkaloid obtained from Vinca rosea. It arrests mitosis in metaphase (although vincristine is more active in this respect) and exhibits greater antimetabolic activity than does vincristine; used in the treatment of Hodgkin's disease, choriocarcinoma, acute and chronic leukaemias, and other neoplastic diseases; blocks microtubule assembly. Synonym: vincaleucoblastine. (05 Mar 2000) |
| vinca alkaloid | <drug, oncology> Anti-cancer drugs originally derived from the common periwinkle Catharantus roseus. Drugs of this type include vincristine, vinblastine. (14 Oct 1997) |
| vinca alkaloids | <chemical> A class of alkaloids from the genus of apocyanaceous woody herbs including periwinkles. They are some of the most useful antineoplastic agent. Pharmacological action: antineoplastic agent, phytogenic, vasodilator agents. (12 Dec 1998) |
| Vinca rosea | A species of myrtle (family Myrtaceae) used in various parts of the world as a home remedy; two active dimeric alkaloids obtained from this plant are vinblastine and vincristine. Synonym: periwinkle. (05 Mar 2000) |
| vincaleucoblastine | A dimeric alkaloid obtained from Vinca rosea. It arrests mitosis in metaphase (although vincristine is more active in this respect) and exhibits greater antimetabolic activity than does vincristine; used in the treatment of Hodgkin's disease, choriocarcinoma, acute and chronic leukaemias, and other neoplastic diseases; blocks microtubule assembly. Synonym: vincaleucoblastine. (05 Mar 2000) |
| vincamine | <chemical> A major alkaloid of vinca minor l., apocynaceae. It has been used therapeutically as a vasodilator and antihypertensive agent, particularly in cerebrovascular disorders. Pharmacological action: antihypertensive agents, vasodilator agents. Chemical name: Eburnamenine-14-carboxylic acid, 14,15-dihydro-14-hydroxy-, methyl ester, (3alpha,14beta,16alpha)- (12 Dec 1998) |
| Vincent's angina | An ulcerative infection of the oral soft tissues including the tonsils and pharynx caused by fusiform and spirochetal organisms; it is usually associated with necrotizing ulcerative gingivitis and may progress to noma. Death from suffocation or sepsis may occur. (05 Mar 2000) |
| Vincent's bacillus | Probably Fusobacterium nucleatum. (05 Mar 2000) |
| Vincent's disease | <disease> An acute or recurrent form of gingivitis of young to middle-aged adults characterised by red and painful gums, fetid breath and gum destruction. Other features may include fever and enlargement of the regional lymph nodes. Pathogenesis of this condition is thought to be secondary to a fusiform bacillus and spirochetal (Treponema vincentii) microorganisms. (14 Oct 1997) |
| Vincent's infection | 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) |
| Vincent's spirillum | The spirillum or spirochete found in association with Vincent's bacillus. Fusobacterium nucleatum is frequently the only bacillus isolated. (05 Mar 2000) |
