Immunofluorescence and enzyme histochemistry on consecutive sections from glycol-methacrylate-embedded bone marrow, lymph node and kidney specimens.
No full textWe describe an immunohistochemical technique adapted to tissues embedded in glycol-methacrylate (GMA). 1-micron-thick GMA sections from kidney, lymph node and bone marrow biopsies were trypsinized and then incubated with F(ab)2 antisera. GMA sections presented some distinct advantages with respect to compared paraffin and cryostatic sections: (1) reduction of background fluorescence, (2) higher resolution of morphologic details, (3) possibility of studying undecalcified bone marrow specimens and (4) possibility of coupling histochemistry with immunofluorescence on consecutive sections. Moreover, in a case of lymphoplasmacytoid lymphoma specific immunostaining for membrane IgM was obtained on GMA sections

IgA-containing plasma cells in the intestinal mucosa of children with selective IgA deficiency.
No full textIn 8 children with selective IgA deficiency (serum IgA less than 5 mg/dl, secretory IgA less than 0.5 mg/dl in unstimulated saliva) immunofluorescent staining of intestinal biopsy specimens revealed the presence of IgA-containing plasma cells. This finding supports the hypothesis that in the intestinal mucosa of patients with IgA deficiency B lymphocytes undergo "sterile" differentiation into IgA-containing plasma cells probably incapable of secreting the IgA synthesize
Reciprocal translocation involving 3q21 in an unusual myeloproliferative disorder with myelodysplastic features and prominent dysmegakaryopoiesis. Cancer Genet Cytogenet ,1991
No full textA case with an atypical myeloproliferative disorder (MPD) characterized by overt dysmyelopoiesis, mostly represented by abnormal thrombopoiesis and showing a t(3;18)(q21;q21), is described. The unusual hematological findings, which characterized a disease borderline between two distinct entities, namely MPD and myelodysplastic syndromes, are also discussed in relation to the cytogenetic abnormality affecting region 3q21 and possibly dictating the abnormal thrombopoiesis
