AIM To evaluate the efficacy of trypan blue for enhancing visualisation during phacoemulsification and foldable lens implantation in cases of cataract with corneal opacities. METHODS 11 eyes of 11 patients with nebulomacular corneal opacities involving the visual axis with partially and visually debilitating cataract underwent trypan blue assisted phacoemulsification with foldable intraocular...

BACKGROUND Incarvillea compacta Maxim. has been used to treat stomach disease in Tibet for many years. The objectives of this study were to explore the anti-cancer ability of trichloromethane fraction of I. compacta Maxim. roots (IC-TCL, R2) in EBV positive AGS cancer cells and its effects on cell cycle arrest, apoptosis and lytic induction. METHODS MTT and trypan blue assays were to detect t...

Dye exclusion tests are used to determine the number of live and dead cells. These assays are based on the principle that intact plasma membranes in live cells exclude specific dyes, whereas dead cells do not. Although widely used, the trypan blue (TB) exclusion assay has limitations. The dye can be incorporated by live cells after a short exposure time, and personal reliability, related to the...

Materials and methods: Th e eff ects of HBO on Leishmania tropica promastigote and amastigote forms were studied at a pressure of 2.5 atmosphere absolute (ata). We examined the cytotoxic eff ect of HBO on promastigotes using the trypan blue exclusion test and the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) dye-reduction assay. To investigate the eff ects of HBO treatment ...

A viable cell count is essential to evaluate the kinetics of cell growth. Since the hemocytometer was first used for counting blood cells, several variants of the methodology have been developed towards reducing the time of analysis and improving accuracy through automation of both sample preparation and counting. The successful implementation of automated techniques relies in the adjustment of...

Aim: Acute myeloid leukemia (AML) is a disease characterized by relapse and treatment resistance in most patients. Therefore, there need for targeted therapies AML. Photodynamic therapy (PDT) promising alternative the of malignant tumors. Also, PDT has potential to be used individually or complementally leukemia. In this study, it was aimed investigate possible effect malachite green (MG)-based...

The thermostable direct hemolysin produced by Vibrio parahaemolyticus showed cytotoxic activity on FL cells derived from human amniotic membrane. Scanning electron micrographs of the whole cells showed that the microvilli on the cell surface decreased in number and changed in shape on treatment with the hemolysin. Most of the microvilli disappeared before death of the cells, as judged from the ...
