OBJECTIVE This prospective study was carried out to assess the diagnostic value of in situ Polymerase Chain Reaction in leprosy, particularly in enhancing the histopathological diagnosis. METHOD Clinical examination of 20 patients (< 16 yr) was done and skin smear for AFB was prepared. Biopsy of lesion site was taken for histopathological examination and in situ PCR testing. RESULTS The his...
Three-dimensional (3D) reconstruction and examination of tissue at microscopic resolution have significant potential to enhance the study of both normal and disease processes, particularly those involving structural changes or those in which the spatial relationship of disease features is important. Although other methods exist for studying tissue in 3D, using conventional histopathological fea...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
Background and Objective: Smoking can be associated with the decreasing gingival blood flow and epithelial changes. The aim of this study was to evaluate the histopathological changes of gingival epithelium and connective tissue in smokers. Methods: The study was case-control. Sixty male patients (28 smokers and 32 nonsmokers) suffering chronic periodontitis were participated...

It is a congenital lesion that can be easily misdiagnosed as malignant tumor, leading to exposing the patient to unnecessarily overtreatment. case report: this is a rare case of congenital colobomatous cyst in an infant girl. the cyst was associated with a microphthalmic glo...
BACKGROUND Dissection of the lymphatic structures in the neck is an integral part of the management of many head and neck cancers. We describe a technique of surgical dissection, preparing the tissue for more precise histological analysis while also reducing operative time and complexity. METHODS When dissected, each level is excised between lymph nodes groups and put into a separate pot of f...
