Toluidine Blue O-Gelatin Gel Dosimeter for Radiation Processing
In this study the spectrophotometric response of the Toluidine Blue O (TBO)-gelatin gel dosimeter irradiated with gamma rays was characterized. Preparation of dyed-gelatin gel takes place in neutral medium; to give eventually gel dosimeter has a sharp absorbance peak at 635 nm that bleaches quantitatively upon irradiation and the colour change can be measured with UV-VIS spectrophotometer. The ...
متن کاملToluidine blue staining identifies high-risk primary oral premalignant lesions with poor outcome.
There is a pressing need for the development of visual aids that will facilitate the detection of oral premalignant lesions (OPLs) with a high-risk of progression. Preliminary data suggest that toluidine blue stain may be preferentially retained by OPLs with high-risk molecular clones. In this study, we monitored OPLs from 100 patients without any history of oral cancer for an average of 44 mon...
متن کاملHistopathologic evaluation of mast cells in reticular and erosive oral lichen planus using toluidine blue staining
Introduction: Oral Lichen Planus (OLP) is one of the most common mucocutaneous lesion, and its etiologic factors have not been elucidated yet. OLP has two different clinical forms including reticular and erosive. Mast cells function in non-specific immunology is an etiologic factor involved in the formation of lichen planus. This study aimed at determining the pattern of mast cells presence in ...
متن کاملPhotosensitization of T2 coliphage with toluidine blue.
The photodynamic action of dyes upon biological systems has been reviewed by Blum (1941). Inactivation of bacteriophage by this process has been studied by Clifton (1931), Perdrau and Todd (1933), Burnet (1933), Morales (1941), and Pacheco and Morales (1941). More recently, Welsh and Adams (1954) and Yamamoto (1956, 1958) investigated the kinetics of photodynamic inactivation of coliphage. In t...
متن کاملIn vitro lethal photosensitization of S. mutans using methylene blue and toluidine blue O as photosensitizers.
The purpose of this in vitro study was to evaluate the antimicrobial effect of photodynamic therapy on Streptococcus mutans (A TCC 25175) suspensions, using a red laser for one minute in combination with toluidine blue O (TBO) or methylene blue (MB). Both photosensitizers were used in three concentrations (25, 10 and 5 mg/L). The activity ofphotosensitizers and laser irradiation were tested sep...
