In this study , Copper oxide as a good and inexpensive adsorbent has been introduced and used for the removal of erythrosine and red carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be interpreted by ...

Male rats were treated of with a diet supplemented daily by the synthetic food colour erythrosine (0.08 and 0.4 g/kg diet) for 30 days. Changes in mutagenic activities, as an index for evaluating of possible toxic effects, were monitored by measuring chromosomal aberrations of rat bone marrow, nucleic acids and total protein concentrations of rat liver and brain. The present study found that er...

The present work was designed to test the toxic impacts exerted by the colour additives erythrosine on the histology, ultrastructure and some serum liver function parameters in male albino rats. Erythrosine in a dose level equals 136 mg/kg bw was given orally to male albino rats for 4, 6 and 8 weeks. This caused time-dependent histological alterations in liver such as cytoplasmic vacuolization ...

Photodynamic Therapy (PDT) involves the administration of a tumor localizing photosensitizing agent, which upon activation with light of an appropriate wavelength leads to the destruction of the tumor cells. The aim of the present study was to determine the efficacy of erythrosine as a photosensitizer for the PDT of oral malignancies. The drug uptake kinetics of erythrosine in malignant (H357) ...

In this study Soure orange skin as a good, natural and inexpensive adsorbent has been introduced and used for the removal of Erythrosine and red Carmoisine dyes from several water solutions successfully. The effect of various parameters such as pH, dye concentration, amount of adsorbent, contact time and temperature on removal processing was investigated. Adsorption isothermal data could be int...

Hybrid H3PMo12O40/polymer composites were proposed here for the simple photocatalytic decomposition of erythrosine B and rose Bengal because their unwanted effect on environmental microorganism. Interestingly, composite exhibited efficient activity dyes under both mild near UV irradiation solar irradiation. High final conversions obtained reaching 81% 86% respectively after 120 min [email prote...

OBJECTIVES The purpose of this study was to evaluate the clinical plaque disclosing agent erythrosine as a photosensitizer in the photodynamic killing of the oral bacterium Streptococcus mutans grown as a biofilm. METHODS S. mutans biofilms of 200 microm thickness were grown in a constant-depth film fermenter. In addition to determining localization of the photosensitizer within biofilms usin...

The synthetic food dyes studied were rose bengal (RB), phroxine (PL), amaranth, erythrosine B (ET), allura red, new coccine, acid red (AR), tartrazine, sunset yellow FCF, brilliant blue FCF, and indigo carmine. First, data confirmed that these dyes were not substrates for CYP2A6, UGT1A6, and UGT2B7. ET inhibited UGT1A6 (glucuronidation of p-nitrophenol) and UGT2B7 (glucuronidation of androstero...
