Tetrazolium violet is a tetrazolium salt and has been proposed as an antitumor agent. In this study, we reported for the first time that tetrazolium violet not only inhibited human lung cancer A549 cell proliferation but also induced apoptosis and blocked cell cycle progression in the G1 phase. The results showed that tetrazolium violet significantly decreased the viability of A549 cells at 5-1...

Background: A highly efficient genetic transformation system is essential for a successful genetic manipulation of the African violet (Saintpaulia ionantha Wendl.). Objectives: Developing a particle bombardment-based genetic transformation system for the African violet. Materials and Methods: A local cultivar of the African violet from Guilan province was used for transformation experiments. Th...

The recent observation of a sharp selective bactericidal property possessed by gentian violet 1 raised the question as to which part of the gentian violet molecule was responsible for the sensitive affinity. It seemed wise to attack this problem by studying substances closely allied to gentian violet in chemical structure, 2 and the results obtained will be briefly reported in the present commu...

conclusions vo can be presented as a safe, well-tolerated, and effective herbal preparation in patients with chronic insomnia. results improvements in sleep and isi scores were significantly greater in patients after a month receiving vo drop in comparison with before starting treatment (p < 0.05). a few patients reported some complications about vo consumption, most of which were mild and no s...

Several studies have validated the effectiveness of narrow-band imaging (NBI) in estimating invasion depth of early colorectal cancers. However, comparative diagnostic accuracy between NBI and chromoendoscopy remains unclear. Other than crystal violet, use of acetic acid as a new staining method to diagnose deep submucosal invasive (SM-d) carcinomas has not been extensively evaluated. We aimed ...

Bacterial colonization of polymeric medical aids causing so-called nosocomial infections is one of the main problems linked with the extensive use of polymeric devices in clinical applications. In this study, the properties of medical-grade polyvinyl chloride were modified by incorporating crystal violet into its bulk structure. Sodium montmorillonite was used as a carrier for the crystal viole...
