We describe a procedure for treatment of thin-layer chromatographic serum lipid patterns so that they may be stained by dyes for evaluation by densitometry. After development of the chromatogram [Clin. Chem. 18, 384 (1972)] the plates are dried and sprayed with butyryl chloride. This esterifies the free cholesterol. After drying, the plate is treated with iodine monobromide, to add iodline to t...
The objective of this study was to evaluate the effect of photodynamic therapy with erythrosine and rose bengal using a light-emitting diode (LED) on planktonic cultures of S. mutans. Ten S. mutans strains, including nine clinical strains and one reference strain (ATCC 35688), were used. Suspensions containing 10⁶ cells/mL were prepared for each strain and were tested under different experiment...
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, 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 t...

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...
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...
rosine B, Tartrazine, Lissamine Green B, Pyronin G, Acetyl Yellow G, Ponceau 6R, Ponceau SX, Food Orange #2, and Food Yellow #3. The concentration of dye tested was 50 mg/ L of incubation mixture (25 pg/tube) in RIA systems for human lutropin (hLH), its alpha and beta subunits, rat LII, rat corticotropin (rACTH), rat insulin, and human thyroxin (T4) and testosterone. (For T4 we usedthe MAGIC-T4...
The effect of erythrosine- and LED-mediated photodynamic therapy (PDT) on planktonic cultures and biofilms of Candida albicans and Candida dubliniensis was evaluated. Planktonic cultures of standardized suspensions (10(6)cells/mL) of C. albicans and C. dubliniensis were treated with erythrosine concentrations of 0.39-200 μM and LEDs in a 96-well microtiter plate. Biofilms formed by C. albicans ...
