The feeding behavior of the heliozoon Actinophrys sol was investigated using the ciliate Colpidium colpoda as food. The ciliate is caught by adhesion to the arms of the heliozoon. Within 20 min the prey is enclosed by a funnel-shaped pseudopodium which progresses over the prey by the action of its differentiated leading edge. Independent Actinophrys cells(More)
The electronic modal lymphocyte volumes of 151 patients with chronic lymphocytic leukemia (CLL) and 305 normal controls were determined by the hydrodynamically focused multi-channel Coulter TF analyser. The mean volumes of the normally distributed groups were 166±19.3 (range 126–216) fl in patients with CLL and 206±14.4 (range 126±246) fl in normal(More)
Die intestinale59Fe-Resorption wurde als Indikator eines prälatenten oder latenten Eisenmangelzustandes bei insgesamt 85 im 4. bis 9. Schwangerschaftsmonat befindlichen Frauen mit dem59Fe-Resorptions-Gesamtkörperretentions-Test gemessen. Die59Fe-Resorption stieg von 31,7±8,1% bei gesunden menstruierenden Frauen über 74,6±17% im 6. Monat, 84±13% im 7. Monat(More)
In order to judge differentiation of cells in soft agar colonies, cytological and cytochemical classification of single cells within these colonies is necessary. In this study, 1,026 colonies from 15 normal and 95 leukemic bone marrows have been evaluated using cytological, cytochemical, and immunocytochemical techniques. In 180 colonies from 15 normal(More)
l hour after i. v. infusion of colloidal iron in iron deficient subjects uniform phagosomal iron granules were observed in macrophages and endothelial cells of several organs. 7 to 10 days later transformation into ferritin could be visualized in macrophages only. Now, these cells showed diffuse iron staining of the cytoplasm due to dispersed ferritin(More)
