Photosensitization 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 کاملIsolation of Serratia marcescens on deoxyribonuclease-toluidine blue-cephalothin agar.
Serratia marcescens was isolated on a new medium-commercial deoxyribonuclease agar with the addition of cephalothin (1,000 mug/ml) and Toluidine Blue (1,000 mug/ml). It was detected in water samples even though it comprised only 0.1 to 0.0001% of the total bacterial population.
متن کاملToluidine blue: A review of its chemistry and clinical utility
Toluidine blue is a basic thiazine metachromatic dye with high affinity for acidic tissue components, thereby staining tissues rich in DNA and RNA. It has found wide applications both as vital staining in living tissues and as a special stain owing to its metachromatic property. Toluidine blue has been used in vivo to identify dysplasia and carcinoma of the oral cavity. Use of toluidine blue in...
متن کاملModified Toluidine Blue: an Alternative Stain for Helicobacter pylori
Helicobacter pylori infection is associated with many gastroduodenal diseases such as peptic ulcer disease and gastric cancer (Uemura et al., 2001). The organism is the major cause of chronic active gastritis resulting in chronic atrophic gastritis and its end stage, gastric atrophy, which is believed to be a precancerous lesion (Pandey et al., 2010). Intestinal metaplasia, usually associated w...
متن کاملToluidine 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 ...
