[Hematologic and surgical problems connected with splenectomy in elderly patients].

The authors carried out a clinical analysis of problems connected with splenectomy in elderly patients treated surgically at the Institute of Haematology in the years 1965-1972. Out of 24 patients aged above 60 years 12 were analysed clinically (8 females and 4 males). Splenectomy was done in these patients from haematological indications (haemolytic anaemia, thrombocytopenia, pancytopenia). In all these cases indications to splenectomy, the course of operation and postoperative period as well as late therapeutic results were assessed. The analysis of these elderly patients showed that the criteria of indications for splenectomy were the same as in other age groups. The choice of surgical method depended in these cases on the clinical and haematological findings, a lack of permanent improvement after conservative treatment, contraindications to immunosuppressive treatment and results of isotope investigations (particularly the values of the spleen-liver index). In most splenectomized patients there were no complications during the operation and in the postoperative period. In 2 cases only acute circulatory failure was observed immediately after the operation. Evaluation of late results showed that the effects of the operation were similar to those in other age groups.

[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.

[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.
