Ultrastructure and Cytokinetics of Leukemic Myeloblasts Containing Giant Granules1
Leukemic myeloblasts containing abnormal granules were studied with ultrastructural, cytochemical, and thymidine label ing techniques to evaluate defects in granulogenesis and pro liferation. Giant granules (1 to 3 /im in diameter) and Auer rods were observed in leukemic cells from two patients, and only rarely were both abnormal granule types observed in the same cell. The lysosomal origin of ...
متن کاملSusceptibility of lactase to luminal proteases in developing rat intestine.
BACKGROUND Postnatal development of rat intestine is associated with a decline in brush-border lactase activity. This phenomenon is similar to the adulthood hypolactasia in humans. However, the mechanism underlying this process is not understood. METHODS The effect of luminal proteases from adult rat intestine on the intestinal lactase activity in animals aged 7, 14, 21 and 30 days was studie...
متن کاملImmediate early genes of glucocorticoid action on the developing intestine.
Prior studies have demonstrated that glucocorticoid hormones elicit functional maturation of the small intestine as evidenced by their ability to induce increases in the expression of various digestive hydrolases, such as sucrase-isomaltase and trehalase. However, these increases have a lag time of approximately 24 h, suggesting that they are secondary effects of hormone action. To identify can...
متن کاملUltrastructure and cytokinetics of leukemic myeloblasts containing giant granules.
Leukemic myeloblasts containing abnormal granules were studied with ultrastructural, cytochemical, and thymidine labeling techniques to evaluate defects in granulogenesis and proliferation. Giant granules (1 to 3 micron in diameter) and Auer rods were observed in leukemic cells from two patients, and only rarely were both abnormal granule types observed in the same cell. The lysosomal origin of...
متن کاملDNA ploidy patterns and cytokinetics of non-Hodgkin's lymphoma.
Flow cytometry studies for cellular DNA analysis were performed in 115 cases of non-Hodgkin's lymphoma, 53 of which had not received any prior chemotherapy or radiotherapy. DNA content was measured in ethanol fixed cells stained with chromomycin A3. According to the criteria of the International Working Formulation there were 43 low grade, 58 intermediate grade, and eight high grade lymphomas; ...
