Influence of Rose Bengal Dimerization on Photosensitization
Photochemistry and Photobiology, 2021AbstractProtein crosslinking photosensitized by rose Bengal (RB2−) has multiple medical applications and understanding the photosensitization mechanism can improve treatment effectiveness. To this end, we investigated the photochemical efficiencies of monomeric RB2− (RBM2−) and dimeric RB2− (RBD2−) and the optimal pH for anaerobic RB2 ...

Excretion of Rose Bengal in Bile
Nature, 1960THE metabolism of rose bengal has been investigated by us in humans as well as in experimental conditions in animals. When we examined the dye by one-dimensional paper chromatography using 25 per cent ethanol and 5 per cent ammonia (1: 1) as a solvent1, we found it contained several components.

PROPERTIES OF ROSE BENGAL: (X) NEW DERIVATIVES OF POLYMER‐ROSE BENGAL
Photochemistry and Photobiology, 1985Abstract— Polymer rose bengal derivatives are converted to their C‐6 ammonium salts. The φ1 O2 derived in CH2C12 is a function of the KB of the neutralizing amine.

I prepared rose bengal biological stain from its powder base to a 1% concentration. It was then impregnated into filter paper and allowed to air dry. The filter paper strips were sterilized and stored for individual use.

What Is Actually Stained by Rose Bengal?
Archives of Ophthalmology, 1992It has been believed that 1% rose bengal does not stain normal, healthy cells but rather stains degenerated or dead cells and mucous strands. In contrast to this conventional knowledge, we discovered that both commercial additive-containing and additive-free rose bengal solutions stained four different types of healthy cultured cells, including rabbit ...

ROSE bengal has been used for chromo-excretion liver tests usually without a more accurate investigation of the composition of the dye. From the results of Stowe et al.1, it appears that only highly halogenated derivatives of fluorescein are selectively excreted by the liver.

Rose Bengal De-iodination in vitro
Nature, 1964ROSE bengal as well as bromsulphalein and indocyanin green are utilized for the study of liver chromo-excretion. Changes of these dyes in the organism were intensively studied and it was ascertained that bromsulphalein is conjugated with glutathione and excreted in the bile. Similar metabolites were not proved for rose bengal and indocyanin green.

The Antiviral Effects of Rose Bengal and Fluorescein
Archives of Ophthalmology, 1987We evaluated the antiviral effects of rose bengal and fluorescein sodium. The direct antiviral activity was determined by an in vitro direct neutralization assay. The 50% inhibitory dose was 16 micrograms/mL for rose bengal and 460 micrograms/mL for fluorescein.

Photosensitized Oxidation of Oxopurines by Rose Bengal
Photochemistry and Photobiology, 1998AbstractPhotosensitized oxidations of oxopurines (OP) as caffeine, theophylline, theobromine and 1,3,7‐trimethyluric acid (TMU) by Rose Bengal were investigated. In all cases photooxidations occur by a type II mechanism. Reactive and nonreactive 1O2 quenching rate constants by OP were determined in different solvents.
