Gentian
Definition:
(n.) Any one of a genus (Gentiana) of herbaceous plants with opposite leaves and a tubular four- or five-lobed corolla, usually blue, but sometimes white, yellow, or red. See Illust. of Capsule.
Example Sentences:

(4) Necrosis after treatment with gentian violet is a rarely seen complication which should be borne in mind.
(5) Gentian violet is a mutagen, a mitotic poison, and a clastogen.
(6) Adding monensin sodium, gentian violet, or ferrous sulfate alone or in combination with copper to the ration did not significantly change the appearance of the ceca.

(13) A photodynamic action of gentian violet has been demonstrated in Trypanosoma cruzi.
(14) The retardation of solute transfer across an oil-water interface caused by the presence of polymer films formed in situ from the monomers has revealed that the methyl derivative forms the more effective barrier to the test solute, gentian violet.
(15) The cytogenetic toxicity of gentian violet in Chinese hamster CHO cells in vitro has been studied by analyzing (1) squash preparations from direct fixation for recording mitotic anomalies and (2) air-dried preparations (with colcemid--hypotonic pretreatments) for recording metaphase chromosome aberrations.

(19) Other pathways of gentian violet metabolism have recently been investigated that involve its oxidative N-demethylation by peroxidases.
(20) A free-radical derivative of gentian violet is also formed by the action of rat liver microsomes, but whether this radical is involved in the cytotoxic effects of gentian violet in mammalian cells remains to be elucidated.
Gentianine
Definition:
(n.) A bitter, crystallizable substance obtained from gentian.
Example Sentences:
