Albumin is most abundant and most studied protein of the circulation. Its biosynthesis is closely dependent on the nutrition, amino acid supply, hormonal millieu, environment, osmotic equilibrium, diseases and some other factors. Albumin is synthetized in the liver on a polyscmes and delivered into the blood streem. Degradation of albumin is practically still unknown and is one of many biological puzzles. Albumin prepared for therapeutic use almost contains dimers, oligomers and polymers which are very important, because they are one of the parameters for evaluation of albumin products quality.

Congenital deficit of Factor VII is a rare deficit perceived within women and men. Clinicaly it is manifested with mild hemoragical diatesa and of laboratory tests: prolonged on stage prothrombin time, reduced activity of Factor VII and normal APTT. In this article we describe the family in which we have found two cases of congenital deficit of Factor VII, biochemical characteristics, differential laboratory diagnosis and correction of deficit in the case of bleeding.

These last few years investigations of the HLA system antigens in children with malignant lymphoreticular diseases have been considered as highly significant. The correlation between the frequency of the HLA system antigens and malignant diseases was studied in order to assess the influence of the immunoregulating and other HLA system genes on inclination toward these diseases, their etiology and epidemiology. The study included 50 children with various forms of lymphoreticular malignant neoplasms treated at the Children's University Hospital in Belgrade.

This paper describes a patient who, after being subjected to repeated blood Transfusions, has developed antibodies to Antigen Cw.

The cases of 91 patients with congenital hemolytic anemia (H.a.) are reported. The causes of congenital H.a. and the laboratory test by which the diagnosis and precise subclassification of the disease were facilitated are indicated. Emphasis is placed on the therapeutic significance of splenectomy in those patients In whom laboratory tests with a radioactive marker [Cr 51]indicated that splenectomy could have a beneficial effect.

The paper describes various forms of shock which arise in pediatric casuistics as well as pathophysiological changes by which these states are accompanied. The main changes take place in microcirculation. The level and the volume of the lesion of cellular tissue structures depend on the athiology, duration and intensity of noxae. The paper gives clinical haemathological and coagulational parameters necessary to a physician for the evaluation of the state of shock of the diseased. It further points out the meaning of intensity of disturbances within circulation, their dependence and repercutions on haemodynamic, haemothological and coagulational findings, especially in early infancy. To enable the application of quick and afficient therapy upon which the result of treatment depends, the papern deals in detail with development of DIC during the Itates of shock, with importance of wound and of quick and precise laborathory detection and differential diagnostics, and with the circumstances which make these phenomena difficult in early infancy. In the treatment of DIC priority is given to intravenous application of AT-III complex human, concentrated and purified, activated in vitro with heparin. Finally there is a description of examinations of pathological-anatomical-hysthological findings of obduced new-borns and infants ill with irreversible shock accompanied by DIC, whose organs show some particular features in relation to adults.

This report presents the case of a 36 year old woman with an inborn haemorrhagic syndrome, who exhibited a lifelong history of spontaneous bruising, nose bleeding, prolonged bleeding after tooth extraction, and menometrorrhagia. The routine tests of haemostasis were consistent with impaired platelet functions. The diagnosis of the "Aspirin-like defect" was made on the basis of the following findings: the bleeding time was prolonged, whereas the platelet count and morphology were normal; platelet retention in glass bead filters was unmeasurable. ADP-induced platelet aggregation was normal, while it was markedly reduced with collagen and epinephrine. The platelet ADP and ATP content, as well as the ATP/ADP ratio were within normal limits. Aggregation of platelets pre-incubated with aspirin was only slightly reduced when induced by ADP, collagen, or epinephrine. These findings suggest that the thrombocytopathy in our patient is due to an impaired ADP release from the platelet granules containing normal quantities of adenine nucleotides. A similar disorder is observed in normal subjects after aspirin ingestion, and therefore the defect described in this paper is referred to as the "Aspirin-like" defect.

A second case of the -D-/-D- blood in this country is described. A woman, belonging to this rare blood group is from the same region, from which is the first our case published 15 years ago.

All previous experiences have shown that the application of blood, blood components and intravenous solutions presents an unreplaceable therapeutical measure in modern surgical-resuscitative management of war injuries. Together with the broad application of the whole blood, there have been also used other blood components (even such as cryoprecipitate and platelet rich plasma). Among intravenous solutions the most frequently mentioned were isotonic saline, Ringer's lactate solution, glucosaline, 5% dextrose solution, dextran solutions and, recently, human albumin solutions. Due to a high risk of transmission of hepatitis virus, the dried pooled human plasma is less frequently used. There is the generally accepted agreement that availability of the sufficient quantity of blood, blood components and intravenous solutions resulted in the decreased mortality of the wounded. The role of intravenous solutions is of particular importance in the initial phase of management of the wounded and in the situations when it is necessary to wait for blood.

The paper presents a girl with cutaneous lymphoma. The onset of the illness was two years ago, and followed by cutaneous lesions, typical Mycosis fungoides and Sêzary's syndrome. After a year, the neoplastic cells penetrated into the peripheral blood, and the development of Sézary's variant of Mycosis fungoidses, was shown. The clinical development of the disease, and the application of hystopathological and laboratory investigations, proved that it was the Sézary's syndrome. When the adequete cytostatic therapy, and radiotherapy, was applied, according to the protocol for curing the malignant non Hodgkin lymphoma, the clinical and haematological remission of disease was performed.
