The spleens were homogenized and suspended in physiological saline. The suspensions were studied for eosinophil count and the percentage of radioactively labelled eosinophils. The corresponding values for the spleens were calculated. At the same time the eosinophil cells and the labelling index in the peripheral blood were studied. \u0000 \u0000 \u0000 \u0000The germ-free rats showed considerably lower counts in the blood and spleen than did the others. In all groups there was parallelism between eosinophils in the blood and in the spleen. \u0000 \u0000 \u0000 \u0000All spleens exhibited eosinopoiesis and some parallelism between this activity and the circulating eosinophils. \u0000 \u0000 \u0000 \u0000Splenectomy in control rats did not give rise to measurable changes in the number of circulating eosinophils. \u0000 \u0000 \u0000 \u0000It is concluded that apart from being formed by local eosinopoiesis, the eosinophilic cells of the spleen have been transported by the blood and stored in the spleen. The function of the spleen as a depot of eosinophilic cells probably plays no major role. Splenic eosinopoiesis is not, and cannot be expected to be, of importance to the number of circulating eosinophils.","PeriodicalId":21489,"journal":{"name":"Scandinavian journal of haematology","volume":"46 1","pages":"8-17"},"PeriodicalIF":0.0,"publicationDate":"2009-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78439112","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the recent reports are almost entirely concerned with the pathological and functional aspects of the disease. In the present retrospective study the clinical features and laboratory data of 12 patients were analyzed together with a series of 123 adequately clinically documented cases from the literature. The Hb level and the sex of the patient proved to be the only parameters having some prognostic value for the survival time after diagnosis. The effect of splenectomy was assessed in two comparable groups of 24 splenectomized and 51 non-splenectomized patients. The operation seemed to be beneficial, but after 2 years the difference was not significant(.05 less than P less than .10). Analysis of subgroups showed that splenectomy was definitely beneficial in women, in patients with a Hb level over 8.0 g/dl or a platelet level above 50 X 10(9)/1, in patients with leucocytes below 3 X 10(9/1, , and also in patients with hepatomegaly (P less than .05 in all cases). These findings suggest that splenectomy is beneficial in cases where anaemia and thrombocytopenia are not very severe; in severe cytopenia the operation does not increase the life expectancy.","PeriodicalId":21489,"journal":{"name":"Scandinavian journal of haematology","volume":"99 1","pages":"60-71"},"PeriodicalIF":0.0,"publicationDate":"2009-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83380333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The abnormal bleeding responded to fibrinogen therapy and epsilon-aminocaproic acid was not used. The patient's plasma contained little fibrinogen capable of clotting without protamine and it inhibited the thrombin clotting time of normal plasma. Increased fibrinolysis was not observed. Serum obtained from the plasma after addition of protamine and concentrated thrombin contained a substance which reacted with an anti-fibrin serum when tested by an immunoelectrophoretic technique. The results confirmed that ‘altered’ incoagulable fibrinogen determinants were present in the patient's blood which may have interfered with the thrombin-fibrinogen reaction. It is suggested that these changes may be due to intravascular coagulation and not only to fibrinogenolysis. Similar but less severe coagulation changes were observed in the infant's cord blood.","PeriodicalId":21489,"journal":{"name":"Scandinavian journal of haematology","volume":"21 1","pages":"26-34"},"PeriodicalIF":0.0,"publicationDate":"2009-04-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87320665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examination of PBN C3b receptors from 154 cases of various haematological disorders revealed a significant proportion of cases with increased numbers of C3b receptor-negative neutrophils.
