Modified 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 کاملModified toluidine blue O stain for Pneumocystis carinii: further evaluation of some technical factors.
A modified toluidine blue O (TBO) stain for Pneumocystis carinii cysts was evaluated with regard to the influence of (i) the age and extent of use of the sulfation reagent, (ii) the source of TBO, (iii) the TBO content of the staining solution, and (iv) the amount of TBO present in the alcohol wash solutions. All TBOs evaluated, except for a new TBO obtained from Roboz Surgical Instrument Co., ...
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 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 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 ...
