The purpose of the present study was to find out if the differences in disappearance rates of T-1824, trypan blue, niagara sky blue and niagara sky blue 6B depend upon the binding of these dyes by the plasma proteins (Gregersen and Rawson, 1943). The affinity of the various dyes for the plasma proteins was investigated: 1, with the electrophoresis method of Tiselius (1937) ; 2, by the ultracent...

Thirteen-week subchronic toxicity studies of direct blue 6, direct black 38, and direct brown 95 dyes were conducted by administering the test chemicals in feed to Fischer 344 rats and B6C3F1 mice. Groups of 10 rats and 10 mice of each sex were administered one of the three dyes at one of five concentrations for 13 weeks and then necropsied, beginning the second day after the end of the dosing ...

BACKGROUND To evaluate the efficacy of trypan blue (0.06%) in posterior capsulorhexis with optic capture in pediatric cataracts. METHODS In this prospective randomized controlled study, trypan blue dye assisted posterior capsulorhexis with optic capture was performed in 18 eyes (group 1) and no dye was used for posterior capsulorhexis (group 2) in 17 eyes. RESULTS The mean size of the poste...

Recently while experimenting with solutions of various dye stuffs on kala-azar serum, we observed that when solutions of methylene blue were left in contact with kala-azar serum, the dye gradually decolourised. We have tried out various strengths of methylene blue solutions varying from 1 in 2,000 to 1 in 80,000 and obtained the most satisfactory results when working with a solution of 1 in 40,...

White rot fungus Marasmius sp. BBKAV79 (GenBank accession number-KP455496, KP455497) exhibited decolourization and degradation of Navy blue HER dye (concentration 50 mg l-l) within 24 h under shaking condition. In the present study, various investigated parameters like initial dye concentration, pH, temperature, carbon and nitrogen sources were optimized to develop a faster decolourization proc...

in the present study, comparison of  photocatalytic activity of nanostructures semiconductor zinc oxide (zno) was prepared using the different methods on the degradation of organic dye such as methylene blue that was investigated. previous studies have proved that such semiconductors can degrade most kinds of persistent organic pollutants, such as detergents, dyes, pesticides and volatile organ...

In order to test photoelectric recording of dye curves, simultaneous determinations of cardiac output were made in 48 patients with heart disease with the Fick and dye-dilution technics. The dye curves were recorded with a Colson densitometer following either intrathoracic or antecubital injection of dye. Both Evans blue and indoeyanine green dyes were employed. Satisfactory agreement was noted...

In dentistry, methylene blue dye (injection USP 1%; American Quinine Co., Inc. Shirley, NY) is mainly used for laboratory research. In endodontics, it is used most often in marginal leakage studies to stain and locate those areas of the root canal system not sealed by the obturating material (1). It is also used to treat methemoglobenemia due to prilocaine toxicity (2, 3). Methyleneblue dye is ...

sawdust which is the main waste from wood industry has been used as a raw material forremoval of brilliant cresyl blue toxic dye. the effects of various parameters such as ph,electrolyte concentration, adsorbent dose, contact time and agitation rate were studied for theremoval of the dye in a concentration of 50 mg l-1. the optimum condition for the studiedparameters was applied for various con...
