necrobiotic disorders/phosphatase

Azo dye methods were used to determine the distribution of acid phosphatase (ACP) and alkaline phosphatase (ALP) in the skin of 25 Beagle dogs. ALP activity was found in dermal papillae of hair follicles regardless of their state of activity, in Huxley's layer of the inner root sheath of anagen

Granuloma annulare is a lymphohistiocytic process of unknown cause characterized by necrobiotic dermal papules. Acetone-fixed frozen sections of eight granuloma annulare lesions were studied for the presence of T-cell subsets, using monoclonal antibodies to T-cell surface antigens. The palisading

Histochemical changes in the heart, liver and kidneys and ultrastructural disorders in cardiomyocytes were studied in 40 white rats with adjuvant disease. Mucoid lesions, hydropyc dystrophy and necribiosis of muscle cells developed in the heart, diffuse extra-intracapillary glomerulonephritis in

Clinically, malignant histiocytosis is a malignant neoplasia with poor prognosis. Diseased are lymphnodes (especially cervical nodes), liver, spleen and bones. Few cases become leukemic. The cells show characteristic pale roundish, often indented nuclei, without large nucleoli and with abundant

The prolonged exposure to formaldehyde induces in the rabbit lung reactional and dystrophic changes involving the intrapulmonary bronchi, the bronchioli and the lung tissue. These changes are represented by bronchial cell hyperplasia with hypermucigenesis, extrusion of bronchial cells, bronchiolar

The present investigation is based on the cytomorphological, histopathological (HE, VG, PAS-Alcian, Safranin 0, Gömöri), histoenzymological (acid phosphatase, chondroitinsulphatase, peroxidase) and immunological (rheumatoid factor (RF), circulating immune complexes (CIC), anticolagen II antibodies

Following necrobiosis of the smooth muscle cells (SMC) of the vessel wall, lysosomes are still able to live for a time in the extracellular space. Here they are known as lysosomal matrix vesicles (MV). Their lysosomal origin can be confirmed by the immunocytochemical demonstration of

The rats were given potassium bichromate (K2Cr2O7) in dose of 2 and 5 mg/kg of body weight and magnesium chloride (MgCl2) in dose of 500 mg/kg for a period of 30 days. The two compounds were also given conjointly (K2Cr2O7-5 mg+MgCl2-500 mg). There were carried out histopathological as well as
