Brucellosis is an important public health problem in Bosnia and Herzegovina. The diagnosis of brucellosis in the country without any experiences with this kind of infection may be very difficult. The aim of this study was to evaluate diagnostic methods: Rose Bengal test, blood cultures and ELISA IgM and IgG in the patients with brucellosis. The study included 91 brucellosis patients in the peri...

(I†• tagged) rose bengal uptake-excre tion test for liver function, as described by Taplin et al. (21), has proven to be a valuable test for a quantitative measure of liver function. In rats, I†• rose bengal uptake and excretion are definitively related to parenchymal cell function (21). Mendeloff (10) showed by fluorescence that injected rose bengal is localized only in parenchymal cells o...

We tested synthetic food colorants for their antioxidative potential by the in vitro superoxide generation assay in differentiated HL-60 cells in response to phorbol ester. Among the 12 colorants tested, such fluorescein-type red colorants as rose bengal showed potent inhibitory activity without any cytotoxicity under dark conditions. The intracellular accumulation and superoxide anion scavengi...

Photogeneration of singlet oxygen (1O2) by rose bengal is improved through the use of a porous monolithic polymer (PMP) as a support, as compared to a classic gel-type resin matrix. This type of monolithic polymeric matrix can be made at a multigram scale in quantitative yields enabling the preparation of large amounts of supported photosensitizer at low cost. The singlet oxygen induced oxidati...

The mechanism of the antiviral activity of hypericin was characterized and compared with that of rose bengal. Both compounds inactivate enveloped (but not unenveloped) viruses upon illumination by visible light. Human immunodeficiency and vesicular stomatitis viruses were photodynamically inactivated by both dyes at nanomolar concentrations. Photodynamic inactivation of fusion (hemolysis) by ve...

In this paper, we report the first observation of metal-enhanced fluorescence emission of fluorophores from paper substrates. The fluorescence intensity is z5and z9-fold brighter from Rose Bengal (RB) and Pt(II) octaethylporphine (PtOEP), respectively, on silver colloid-deposited paper as compared to uncoated paper. In addition, a reduced lifetime of RB near to silver particles (0.77 ns) was ob...

Optical properties in terms of the complex-valued dielectric function were determined for spin-coated films of a Rose Bengal derivative using variable angle of incidence spectroscopic ellipsometry in the visible and infrared wavelength regions. In addition, the thickness and roughness of the films were determined and related to the solution concentration of Rose Bengal. Switching between two di...

It has been previously reported that such chemicals as hematoporphyrin are activated by ultrasound energy. In the present study, in vitro ultrasound cell killing effect in the presence of the non-toxic red stain, Rose Bengal, was evaluated. Gastric cancer cells were exposed to ultrasound with or without Rose Bengal. Greater ultrasound cell killing effects were obtained in drug included samples....

OBJECTIVES To determine the performance of different tear and salivary tests applied in Sjögren's syndrome (SS) and to disclose how these tests relate to common serologic tests in SS. DESIGN In addition to the routine ocular and oral tests for diagnosing SS (Schirmer test, rose bengal score, unstimulated whole saliva flow, and parotid sialography), tear breakup time and flow rate of glandular...
