background: rose bengal is a common test for serologic diagnosis of brucellosis. the aim of this study was to evaluate the agreement rate between modified rose bengal, rose bengal and rapid wright tests for detection of antibody positive serum samples.  methods: c ross section study was designed. 941 serum sample of patients referred to the central medical laboratory of kermanshah, were evaluat...

PURPOSE In vivo, the ophthalmic dye rose bengal displays profound antiviral effects against herpes simplex virus (HSV)-1, thus limiting its utility in diagnosis of epithelial keratitis when used before viral culture is performed. In contrast, lissamine green B does not possess significant antiviral activity in vivo. To determine whether polymerase chain reaction (PCR) could successfully detect ...

introduction: the treatment of cutaneous leishmaniasis (cl) is based primarily on the use of pentavalent antimonials, which may lead to many side effects limiting their use. photodynamic therapy (pdt) is an alternative for the treatment of cl, and some xanthene dyes have the potential for use in pdt. methods: the xanthenes rose bengal b (rb) and its derivatives rose bengal methyl ester (rbmet),...

The stopped-flow mixing technique was used to develop a very fast, sensitive and accurate method for determining total proteins. The method is based on the lower fluorescence of Rose Bengal caused by binding of the dye to the proteins. The decrease in the fluorescence intensity, measured at 572 nm with excitation 555 nm, was linearly related to protein concentration from 1.3 to 24.5 micrograms ...

Rose bengal dye is thought to highlight corneal lesions induced by herpes simplex virus type 1 (HSV-1) by virtue of its binding to dead or dying HSV-1-infected epithelial cells. However, whether rose bengal binds specifically to damaged versus normal corneal epithelial cells is unclear. To determine the binding properties of rose bengal, the authors compared binding of the dye to HSV-1-infected...

One hundred and forty two patients (62 with definite Sjögren's syndrome, 24 with probable Sjögren's syndrome, and 56 in whom Sjögren's syndrome was finally ruled out) were studied. Schirmer's test and rose bengal staining for the diagnosis of keratoconjunctivitis sicca and salivary scintigraphy and a labial biopsy sample for the diagnosis of xerostomaia were studied in all patients. Rose bengal...

The liver is an organ, which defies investigation in several ways. It is hidden in the right upper quadrant of the abdomen and away from other viscera in a "secret cave". Being a large organ, it presents problems in the localisation of lesions, particularly in the depth of the lobe. Further, its several functions are not affected to the same extent in disease. It also has a large reserve capaci...
