The giant anteater (Myrmecophaga tridactyla) is a vulnerable species from Central and South America, considered possibly extinct in Belize, Guatemala, El Salvador, Uruguay. Due to the species’ conservation reproductive importance, this research aimed characterize morphology, histochemical, immunohistochemical, ultrastructural feature of prostate gland. For this, we collected 11 glands performed...

AIMS To develop and immunohistochemical staining method for cryostat and paraffin wax sections so that two different antigens in the same section of tissues could be detected by combining immunoenzyme and immunofluorescence techniques. METHODS This double immunohistochemical staining method combines alkaline phosphatase-anti-alkaline phosphatase (APAAP) using New Fuchsin as a chromogen and in...

Desmoplastic melanoma(DM) is a subtype of malignant melanoma, and there are very few reports on the occurrence this disease in oral region. Since DM mainly composed achromatic spindleshaped tumor cells, its clinical histopathological diagnoses difficult. However, immunohistochemical staining useful for diagnosis DM.

the study was undertaken to answer the question that how many patients with pigmentation of back and arms actually have amyloid deposits in pathology. 44 patients presenting with diffuse pigmentation of back and arms (dpoba) were selected. skin biopsies were performed in all cases from the affected sites. on all formalin fixed and paraffin embedded specimens, the following histochemical stains ...

AIMS To investigate (1) whether adequate immunohistochemical staining can be achieved on sections cut from plastic embedded bone marrow trephine biopsy specimens after microwave heating in citrate buffer; and (2) whether this immunohistochemical staining is comparable with that achieved on routine sections cut from paraffin wax embedded trephine biopsy specimens after decalcification procedures...
