BACKGROUND AND OBJECTIVES In vivo stains are prompt resources, which have emerged, in the recent years, to aid as clinical diagnostic tools in detecting early premalignant and malignant lesions. The aim of the study was to determine the diagnostic efficiency of toluidine blue with Lugol's iodine in oral premalignancies and malignancies and to evaluate the reliability of in vivo staining with to...
BACKGROUND Ocular rhinosporidiosis is a chronic granulomatous infection caused by a newly classified organism that is neither a fungus nor bacterium. It often presents as a benign conjunctival tumour but may mimic other ocular conditions. It is most often described in India. In Africa cases have been reported from South Africa, Kenya, Tanzania, Malawi, Uganda, Congo and Ivory Coast. CASE PRES...
Staining of mast cells (MCs), including porcine ones, is critically dependent upon the fixation and staining technique. In the pig, mucosal and submucosal MCs do not stain or stain only faintly after formalin fixation. Some fixation methods are particularly recommended for MC staining, for example the fixation with Carnoy or lead salts. Zinc salt fixation (ZSF) has been reported to work excelle...
Purpose: The objects of this study were to compare biological properties of a native articular cartilage extracellular matrix (ACECM)-derived oriented scaffold and the Chondro-Gide bilayered scaffold. Methods: The ACECM oriented scaffold (No. 4131) and the Chondro-Gide scaffold (No. 4132) compared form (I) The physical properties (II) FDA/Pl staining, and frozen sections were stained with tolui...
the present study was carried out for evaluation of calcoflour white staining (cws) as a rapid method for detection of pneumocystis carinii in respiratory specimens of rats as an animal model for human infection. a total of 35 spraque – dawley rats were divided into two groups. group1 (20 rats) received increasing doses of dexamethasone subcutaneously, and group 2(15 rats)as control group that ...
The object of this study was to find a suitable staining method for P.carinii. This parasite is not easily stained and clinical signs are not specific for the diagnosis of P.carinii pneumonia and therefore optimal laboratory methods for observing the organism are extremely valuable. In all 17 new conventional and modified staining techniques were used on lung impression smears and tissue sectio...
Cultured fibroblasts from the genetic mucopolysaccharidoses store higher than normal amounts of the polyanionic glycosaminoglycans (mucopolysaccharides); histochemical staining with the cationic dyes toluidine blue O and Alcian blue detects such intracellular accumulation. With these stains as phenotypic markers, correction of the cellular abnormality by fibroblasts derived from different patie...
