The relative contribution of transfusions of adult blood to the development of retrolental fibroplasia (RLF) in very low-birth-weight infants was examined. Five years of experience with the expanded use of replacement and exchange transfusions in 90 infants with birth weight ≤1,250 gm was reviewed. Twenty percent of the infants developed cicatricial RLF. Exchange transfusion was not related to development of cicatricial RLF. The incidence of RLF in infants receiving ≥130 ml of packed red blood cells per kilogram of birth weight as replacement blood transfusion (RBT) was significantly higher (42.9%) than that in infants receiving 61 to 131 ml of packed red blood cells per kilogram (15.4%) and infants receiving ≤60 ml of packed red blood cells per kilogram (0%), P < .001. The need for RBT, however, was strongly correlated (r = .85, P < .001) with increasing duration of O2 therapy. When O2 therapy was controlled for, the association between RBT and RLF did not achieve statistical significance (P = .07). The association between RBT and RLF remained significant when adjusted for duration of therapy in fractional inspired oxygen (FIO2) >0.4. Further detailed studies of large numbers of susceptible infants are warranted to assess the magnitude of the contribution of transfusions of adult blood to development of RLF.

The aim of the investigation was to study the morphological condition of blood cells in the basins of the ischemic limbs and their dynamics as a result of various types of surgical treatment. Implementation of combined surgical treatment has a more normalizing effect in comparison with isolated reconstructive surgical treatment. The use of lumbar sympathectomy in patients with occlusive lesions of arteries of lower limbs and varying degrees of ischemia reduces endothelial dysfunction and normalizes a number of parameters describing the morphology and functioning of red blood cells and platelets. There was detected the deformation of red blood cells indicating that the restoration of the plasticity of red blood cell membranes significally reduced the degree of agglutination of red blood cells. According to obtained data the influence of sympathectomy depends on the severity of the disease in general the highest efficiency is observed at the II and III degree of ischemia.

Some hematological values, blood total protein, protein fractions, and minerals such as calcium and phosphorus of takhi, which are now being reintroduced in Khustain natural park, were measured. There were 8.3 million red blood cells and 8000 white blood cells in 1 mm3 whole blood of takhi reintroduced in Khustain natural park, and hemoglobin was 179.6±3.2 g/l. As well, total proteins, calcium and phosphorus of takhi were 67± 0.6 g/l, 2.1±0.31 mmol/l, and 1.1±0.2 mmol/l respectively and they were similar to those in Mongolian horses. It has been necessary to investigate further adaptability of takhi in asscoation with both internal and external environments of its body.DOI: http://dx.doi.org/10.5564/mjas.v11i2.206 Mongolian Journal of Agricultural Sciences Vol.11(2) 2013 pp.3-6

e22007 Background: The purpose of the study was to analyze phenotypic characteristics of red blood cells by the AVBO, Rh and Kell systems in children with cancer. Methods: ABO and Rh blood groups were determined and erythrocyte antigens (D, С, с, Сw, Е, е, К, k) were typed (AutoVue Innova, USA) in blood samples of 114 children with solid tumors. Results: ABO blood groups distribution was as follows: A(II) > O(I) > B(III) > AB(IV) with A(II) prevalence. Rh(D)-positive phenotype was observed in 82 (71.9%) patients of 114: 47 (57.3%) boys and 35 (42.6%) girls. 32 (28.1%) patients of 114 were Rh(D)-negative: 15 (46.8%) boys and 17 (53.1%) girls. Only 8 (7%) children were Kell-positive, which was similar to the antigen prevalence in European population. 4 erythrocyte phenotypes were the most frequent in Rh(D)-positive patients: СсDееK− (34.1%), ССDееK− (22.0%), ccDEeK− (13.4%) and СсDЕеK− (11.0%). I.e., more than a half of children with oncopathologies (56.1%) had Kell-negative phenotypes, СсDееK− and ССDееK−. 86.4% of Rh(D)-positive patients had homozygous combinations of Rhesus antigens causing transfusion reactions - СС, сc, ЕЕ and ее. 18 (22.0%) of Rh(D)-positive patients were homozygous for the C antigen and 64 (78.0%), i.e. every third patient, had the c antigen. Children with the C antigen may be sensitized to the c antigen through blood transfusion with subsequent development of hemolytic complications. The K (Cellano) antigen was found in all children, and 93% of them had kk phenotype and 7% - Kk. The Сw (Willis) antigen was revealed only in 5 (6.0%) Rh(D)-positive patients with rare phenotypes - CwCceeK-, CwccEeK-, CwCcEEK-, CwCcEeK-. Matching a donor for patients with one of these phenotypes could pose a problem. Conclusions: Studying phenotypic characteristics of red blood cells is necessary for providing a successful blood transfusion, especially in children Kell-positive for the K antigen, in children homozygous for the C antigen with ССDееК- phenotype and in children with the Сw antigen and СwСсееК-, СwссЕеК-, СwСсЕЕК- and СwСсЕеК- phenotypes.

Blood transfusion is associated with immunosuppression, although the exact etiology of the immunosuppressive effect is not fully understood. The clinical significance of the immunosuppressive effect of blood transfusion has been examined in three situations: (1) studies of renal allograft survival after renal transplantation, (2) outcome studies in patients who have had surgical resection of solid cancer tumors, and (3) studies of infection rates in postoperative patients. In each scenario, the data support the conclusion that transfusion is associated with immunosuppression as manifested by increased renal allograft survival, increased recurrence and mortality rates in patients with cancer, and increased infection rates in postoperative patients who are transfused. Not all studies demonstrate an immunosuppressive effect of transfusion. There are several possible explanations for these discrepancies. First, prognostic variables other than transfusion itself account for the outcome results in these retrospective studies. Second, the extent of immunosuppression may be influenced by the type of blood product transfused, the amount transfused, and the timing of the transfusion; these factors have not been considered in all studies. For example, whole blood has been implicated as having a greater immunosuppressive effect than packed red blood cells, and many studies have shown that more than three units of packed red blood cells are necessary to affect outcome. Controlled animal studies have tested the hypothesis that transfusions increase solid tumor growth or the risk for infection. These studies have yielded conflicting results. Nevertheless, evidence that blood transfusion influences clinical outcome mitigates that a decision to transfuse must consider both risks and benefits of a transfusion; the possible consequences of immunosuppression must be included among the risks. Use of autologous blood, erythropoietin, and, in the future, synthetic hemoglobin may lead to improved outcome in patients with certain disease processes.

A technique for determining the large angle light-scattering patterns of biologic cells has been developed and applied to the measurement of isolated calf oligodendroglia. Preliminary results indicate that light-scattering information can be used to discriminate between oligodendroglia, subcellular debris and red blood cells and also suggest that oligodendroglia can be distinguished from neurons.

Red blood cells are the most required blood transfusion products worldwide. Safety and efficacy of blood transfusion are still relevant issues. Clarification of the causes and mechanisms of post-transfusion complications requires additional research.Aim of the review is to summarize the data of clinical and research studies on transfusion of red blood cell suspension with various storage times.Material. We selected 76 sources from Web of Science, Scopus, and RSCI databases containing pertinent clinical and scientific research data, as well as blood transfusion guidelines.Results. We reviewed the main stages of preparation and storage of filtered red blood cells, described biochemical and structural alterations occurring during blood storage, summarized clinical data on post-transfusion complications, and analyzed clinical consequences and molecular structure abnormalities of red blood cells in relation to their storage time.Conclusion. During long-term storage, red blood cells undergo significant structural and metabolic changes. The clinical use of relatively «old» red blood cells increases the risk of post-transfusion complications. However, the pathophysiological differences between «young» and «old» erythrocytes remain unclear. Large clinical and molecular research studies may add to our understanding of the complex issues related to blood transfusion.
