    Notes: Abstract Background: This study was designed to explore the effectiveness and tolerability of a weekly regimen of epirubicin and vinorelbine plus granulocyte colony-stimulating factor (G-CSF). Patients and methods: Fifty-two patients with previously untreated advanced breast cancer were treated with epirubicin (25 mg/m2/week) and vinorelbine (25 mg/m2/week) with G-CSF support, for 24 consecutive weeks. Results: The median number of courses per patient was 22 (range 10–24). The administered dose intensity was 23 mg/m2 for both epirubicin and vinorelbine. Ten complete responses (19%) and 30 partial responses (58%) were obtained, for an overall response rate of 77%. None of the patients progressed during treatment. The median response duration and time to progression were both 10 months. A total of 1065 courses were assessed for toxicity. Grade 3 neutropenia was the most common toxic manifestation, (39% of patients), without febrile neutropenia or neutropenic sepsis. Two patients had grade 3 cardiac toxicity, which regressed without sequelae. Median survival was 31 months, with a median follow-up of 24 months (range 9–40). Conclusions: Owing to its effectiveness and tolerability, the weekly regimen of epirubicin and vinorelbine plus G-CSF may represent an acceptable alternative for patients with untreated metastatic breast cancer. It could be tested in the adjuvant and neoadjuvant setting.

    Morphohistochemical changes of the blood cells in the hibernating frog (Rana esculenta L.) (1991)

    Notes: Abstract Some morphological features (degree of nuclear segmentation in neutrophils and eosinophils), histochemical patterns (DHFR, LDH, G6PDH) and, in addition, the nucleic acid distribution (DNA, RNA with acridine orange) in the peripheral blood cells of Rana esculenta, during the hibernation phase were investigated. All the observed parameters varied significantly in the frog during hibernation in comparison with the active period. The most evident changes were an increase in the nuclear segmentation of the neutrophils and a lower activity of the histochemically demonstrable DHFR and LDH, probably due to cell ageing. These findings suggest that, in hibernating frogs, there is an increase in the life span of the peripheral blood cells as a consequence of a reduced metabolic activity and a slowing of haematopoiesis.

    Ultrastructure and cytochemistry of circulating erythrocytes during the annual cycle of Rana esculenta L. (1992)

    Notes: Abstract Morphometrical (image analysis of cell and nuclear shape factor), morphological (electron microscopy) and cytochemical (acridine orange fluoro-chromasia and propidium iodide-DNA flow cytometry) features of circulating red blood cells were investigated during two periods of the annual cycle of Rana esculenta: the active phase (July) and the underground hibernating phase (January). The results showed that the hibernating phase is marked by more homogeneity of the red cells, both at nuclear (strongly condensed chromatin) and cytoplasmic level (loss of intact organelles and acridine orange fluorochromasia). The almost complete disappearance of the ‘immature’ erythrocytes from the circulation, during the hibernating phase, should be related to a decrease of haemopoietic activity and to an increase of life span accompanied by uncommon storage in different organs both at vascular and intracellular level.
