In this research one case of chronic myelogenous eosinophilic leukemia (pbe) transformed into myeloblastic crisis in male patient aged 24, efficiently treated chemotherapy with following performing allogenic bone marrow transplantation was represented. The patients was admitted to the Department of Hematology with the cause of increased leucocytosis (up to 19.9 x 10(9)/l), eosinophilia (up to 15.3 x 10(9)/l), enlarged percentage of eosinophillic granulocytes in bone marrow, splenomegaly, anaemia and thrombocytopenia. Cytogenetic tests did not reveal any chromosomal disturbances, and PCR test did not detect bcr/abl rearanzation. After 7 monthly period of chronic phase of disease there was appeared symptoms of blastic acceleration myelogenous disease i.e. enlargement of splenomegaly, intensification of anaemia and thrombocytopenia, very fast increasing leucocytosis in short time together with presence of myeloblasts in blood and bone marrow smear tests. Blastic acceleration pbe with eosinophils dominant in bone marrow was confirmed by flow cytometry. Induction chemotherapy according to schedule HAR (Hydroxyurea--H, Arabinoside Cytosine--A, Doxorubicin--R), consolidation and irradiation of spleen allowed to receive complete remission. The patients was undergone allogenic bone marrow transplantation (allo-BMT) from related donor (younger brother). The follow-up with the period 18 months after allo-BMT has not revealed the relapse of disease.

[Role of spleen in leukocyte kinetics in dog].

In 9 dogs blood samples were obtained from the splenic vein and artery under general anaesthesia with Eunarcon, the quantitative and qualitative composition of white blood cells was compared and it was found that canine spleen can release or retain granulocytes and mononuclear cells simultaneously or any of these cells separately.

Differences in the composition of leucoyctes in the splenic artery and vein in rabbits, and dogs.

Differences in the composition of leucocytes in the splenic artery and vein in rabbits, and dogs. Acta Physiol. Pol. 1975, 26 (1): 33-39. Blood samples were taken from the splenic artery and splenic vein of 14 rabbits and 9 dogs under general anaesthesia (with hexobarbital sodium in rabbits and Eunarcon in dogs) to compare the quantitative and qualitative composition of white blood cells. It was found that the rabbit spleen releases into the circulation mononuclear cells which do not differ in their size from cells of the blood flowing into the spleen, and that it can retain or release granulocytes, probably due to their intravascular margination. The dog spleen can retain or release granulocytes and mononuclears simultaneously or separately, probably due to the mechanism which includes spontaneous contraction of the spleen.

[Storage of human bone marrow at - 196 degrees C].

The paper contains a description of the method of human bone marrow storage at -196 degrees C using DMSO and glycerol as cryoprotective agents. In the light of determinations of the count of nucleated cells, their viability, myelograms and blastic transformation of lymphocytes it was found that DMSO is a more effective cryoprotective agent than glycerol for storage of human bone marrow at low temperatures.

[Role of human spleen in the release and sequestration of white blood cells].

In 21 patients during operation blood samples were obtained from splenic vein and artery immediately before splenectomy for determination of qualitative and quantitative composition of white blood cells to establish the role of the spleen in their release and sequestration. It was found that the spleen released into circulation mononuclear cells whose number, size of nucleus and glycogen content of the cytoplasm varied individually in various cases. Besides that the spleen releases and sequestrates granulocytes, most probably as a result of intravascular shifts in the marginal and circulating cell pools induced, among others, by contractions of the spleen.
