    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.

    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.

    Notes: Abstract Morphocytochemical correlation between proliferation (BrdU uptake) of the haemopoietic liver subcapsular tissue and peripheral blood cell characteristics was performed during active (summer) and hibernating (winter) periods in two Urodele species: Triturus carnifex and Triturus alpestris. The significant decrease of the haemopoietic cell proliferation during the hibernation was accompanied by some modifications both at erythrocyte and leucocyte level. This situation was primarily characterised by a hypofunctionality and ageing of these cells with the disappearance of immature elements from the circulation and cell loss by apoptotic mechanisms. The results indicate that the condition of low metabolism during the winter period in these Urodeles involved deep changes in the physiology of haemopoietic tissue and blood circulating cells.
