Abstract
Chronic lymphocytic leukaemia (CLL) is the most common adult leukaemia characterised by the accumulation of monoclonal CD5 + B-lymphocytes. The pathogenesis and the biology of CLL is complex and many details are still unknown. Several molecular biological methods have been used in the investigation of CLL, among them the study of apoptosis appears to be one of the most important. Initial experiences obtained by the spontaneous and fludarabine induced apoptosis, multidrug resistance (MDR)-test and fluorescent in situ hybridization (FISH) are reported by the authors. Apoptosis of CLL cells could be induced by fludarabine, while more studies should be performed to determine the exact role of MDR-test and FISH.

Abstract
Chronic myelogenous leukaemia is a clonal myeloproliferative stem cell disease. Its cytogenetical hallmark is the Philadelphia chromosome (Ph) or the BCR/ABL fusion gene. Their identification is important both in the diagnosis and the follow-up of the disease. In our department we have investigated the BCR/ABL gene arrangement in 21 patients with fluorescence in situ hybridization. The aim of the analysis in freshly suspected patients without any previous therapy was to confirm diagnosis and mapping the ratio of Philadelphia positive cells. In contrast to the 95-100% Ph-positivity of mononuclear cells by classical cytogenetical examinations we found BCR/ABL gene arrangement only in various but always lower proportions. Therefore the latter examination gives a better representation of residual normal hemopoesis. Out of 9 patients who had received interferon treatment for at least 6 months, 4 gave a major, 4 a minor cytogenetical answer and in 1 case there was no cytogenetical response. Seven patients reached a complete and 2 a partial hematological remission. Among 5 other patients receiving interferon treatment, in 2 cases with double Ph-positivity we found a rapid progression. The data of 3 patients had to be excluded from the evaluation due to the so far short following time.

Abstract
Hairy cell leukaemia (HCL) is a rare, clinically and haematologically well characterised entity. The prognosis of patients with hairy cell leukaemia has significantly improved due to the new therapeutic approaches. Development of diagnostic and therapeutic methods, together with the analysis of their own hairy cell leukaemia patients, is reviewed by the authors. Between 1977 and 1998 twenty five patients (16 male, 9 female) were treated. The malignant cells were usually analysed by morphological and cytochemical methods and recently flow cytometric analysis could be performed in eight patients. Splenectomy with lethal outcome in six patients was performed in 21 cases. Approximately one third of patients received interferon, while 2-chlorodeoxyadenosine was given only to three patients. Favourable experiences obtained by splenectomy and efficacy of interferon treatment are emphasised, but according to the literature and their own results administration of purine analogues can be highly recommended in the future.

Abstract
Because platelets interact with fibrinolysis in a complex manner, it can be expected that with abnormal platelet numbers and quality this interference can be even more profound. The aim of this work was to study the lysis-resistance of platelet-rich clots in diseases with high platelet counts: polycythemia vera (PV), essential thrombocythemia (ET) and to make comparison with polyglobulia (PG). Platelet-rich plasma (PRP) and platelet-poor plasma (PPP) were analyzed by an in vitro clot lysis test. Plasminogen activator inhibitor-1 (PAI-1) activity was measured in plasma and in the supernatants of the washed and gel-filtered platelets after activation by thrombin. The lysis showed decreased speed of PPP-clots in PV and ET. This phenomenon was even more marked in PRP-clots from PV and ET, but further increased lysis resistance after retraction was not observed in PV and ET, most likely due to abnormal platelet functions. Our results suggest that the fibrinolytic activity is reduced in PV and ET, and may play a role both in the increased aptitude for venous thrombosis and in the arterial complications. These are partly caused by higher plasmatic PAI-1 activity as well as by more active platelet PAI-1. The PAI-1 activity was significantly higher in the supernatants of the washed and gel-filtered platelets of PV after activation by thrombin compared with controls. Other factors might have influenced the reduced fibrinolysis.

Abstract
Pure red cell aplasia (PRCA) is a rare disorder, which is characterized by severe anaemia associated with reticulocytopenia and absence of erythroid precursor cell from the bone marrow. Mostly immunological mechanisms have a role in its pathogenesis. Primarily the acquired, idiopathic type occurs in adults, however, it is rarely associated with other disorders (autoimmune-, and lymphoproliferative diseases, etc.). The authors present a patient with B-cell chronic lymphocytic leukemia associated with PRCA, which was successfully treated with cyclosporine. The pathogenesis and the therapy of the PRCA is also summarized.

Abstract
A case of a familial porphyria cutanea tarda (PCT-II) is reported in which the clinically overt form of PCT was provoked by factors relating to chronic lymphoid leukemia (CLL). Typical lesions of PCT developed on a 55-year-old woman after several blood transfusions and chlorambucil treatment. Besides these provoking factors, cytomegalovirus (CMV) infection was diagnosed. Erythrocyte uroporphyrinogen decarboxylase activity was about 50% of normal in the patient and in her two children. This case supports the suggestion that development of PCT in patients with hematological disorders is more than coincidental but may in fact be provoked by exogenous factors relating to the treatment of leukemia.

Abstract
Results obtained by a simple in vitro clot lysis test in polycythemia vera, polyglobulia, essential thrombocythemia and chronic immun thrombocytopenic purpura are reported. Increased lysis resistance of the platelet-rich clots was demonstrated in polycythemia and essential thrombocythemia, ostensibly caused by the high plasma level of plasminogen activator inhibitor-1. Following retraction of platelet-rich clots no further increase of lysis-resistance occurred in polycythemia and essential thrombocythemia. This phenomenon is most likely due to abnormal platelet function. The well known thromboembolic complications may at least partly result from the impaired fibrinolysis in diseases with high platelet counts.

Abstract
Eosinophil leukaemia is a rare and poorly defined entity characterized by neoplastic proliferation of eosinophil cell line. This form of the hypereosinophilic state is considered to be a variant form of CML, although as a diseases entity is not generally accepted. A history of a patients is reported, whose clinical course is thought to fulfill the requirements of eosinophil leukaemia. On the basis of the initial results (pathological lymphogram, eosinophilia, Ph-negativity) lymphogranulomatosis was suspected and explorative laparotomy was performed. However, only marked eosinophilic infiltration of the spleen was detected. After splenectomy his disease was stable without treatment for six months when his leukocytosis and eosinophilia increased. Despite the administration of hydroxyurea the leukocyte count exceeded 100 x 10(9)/l (eosinophil cells 70%), and the bone marrow revealed massive (80%) eosinophilic infiltration. Neither Ph-chromosome, nor cabl and bcr gen rearrangement were demonstrated, but the expression and amplification of c-myc oncogene indicated disease progression. Interferon therapy produced long-term clinical and haematological improvement, but blastic transformation was developed in the second year of his disease. Autopsy showed multiple organ involvement characteristic of CML, but no marked eosinophilic infiltration was found. The feature of this case suggest that eosinophil leukaemia might represent an uncommon form of Ph-negative CML.

Abstract
Two secondary acute leukaemias out of 166 patients with Hodgkin's disease were detected. At a young female patient treated only with chemotherapy the acute leukaemia developed 39 months following the diagnosis of Hodgkin's disease. Phenotype of leukaemic blast cells could not be determined exactly. After a short complete remission (1,5 month) the patient died because of the progression of her leukaemic process. The other young male patient treated with radio- and chemotherapy had six years disease free interval between the diagnosis of two malignant diseases. The combined cytostatic treatment of his acute lymphoblastic leukaemia resulted complete remission that lasted for one year but later the progression of leukaemia caused death. In connection with these cases the authors reviewed the current questions of treatment related acute leukaemias in Hodgkin's disease.

Abstract
Clinical experiences on seven patients suffering from hairy cell leukaemia are presented. The disease was most often identified at age above 50 and was more frequent in men. Splenomegaly and infiltration of bone marrow or spleen with tartrat resistant acid phosphatase positive lymphoid cells were detected in all cases. Splenectomy resulted complete clinical remission in six and partial remission in one patient. Two patients have died. The mean survival time is five years. The surviving patients are in good clinical remission.

Abstract
Diacetyldianhydrogalactitol (DADAG), a new alkylating sugar alcohol derivative, was administered as single, 30-min infusions in doses ranging from 390 to 1200 mg/m2. The dose-limiting toxicity was myelosuppression. The median times to WBC nadir and regeneration were 16 and 21 days, and to platelet nadir and recovery 20 and 27, respectively. Nausea and vomiting occurred frequently and were of moderate severity. For phase II studies 900 mg/m2 DADAG given every 4-6 weeks is recommended. The area under the plasma concentration time curve (AUC) for DADAG did not increase in proportion with dose escalation; it changed only from 235.5 +/- 70.7 to 262.4 +/- 71.5 micrograms h ml-1 between doses of 690 and 1050 mg/m2. No correlations between the dose administered and the nadir values for haemoglobin concentration, WBC and platelet counts, or the number of episodes of vomiting were demonstrable in this dose range. Such an association was revealed, however, when the above biological variables were related to the individual AUC for DADAG.
