Abstract
Umbilical cord blood (CB) transplantation is thought to be associated with a reduced risk of severe graft-versus-host-disease (GVHD) compared with bone marrow transplantation (BMT). The cytokine cascade is known to be important in the pathogenesis of GVHD; however, previous studies investigating the cytokine secretion pattern of CB cells have been contradictory because of variations in experimental techniques. In this study, the cytokine profile of cord and adult blood lymphocytes and lymphocyte subsets has been assessed at the single-cell level by flow cytometry, using CD4/CD8 and CD45RA/CD45RO markers. Cord and adult blood mononuclear cells were stimulated with phorbol 12-myristate 13-acetate (PMA) and ionomycin in the presence of monensin. After 4 to 24 hours of incubation, interleukin-2 (IL-2), IL-4, interferon-gamma (IFN-gamma), and tumor necrosis factor-alpha (TNF-alpha) production was measured by three-color flow cytometry. The results show that cord blood lymphocytes (CBL) produce less IL-2, IL-4, IFN-gamma, and TNF-alpha than adult peripheral blood lymphocytes (ABL). Further subset analysis showed that in CBL the majority of cytokine producing cells were CD4(+)CD45RA+, whereas in ABL the cytokine-producing cells were both CD4(+)CD45RO+ and CD8(+)CD45RO+. These results suggest that the reduced incidence of GVHD in CB transplantation may partly due to the altered cytokine profile seen in CBL.

Abstract
Cord blood (CB) contains a sufficient number of haemopoietic progenitor cells and can be used as an alternative to bone marrow transplantation. To date, a number of transplants using cord blood-derived stem cells from HLA-identical siblings and unrelated donors have been successfully performed. However, only approximately 30% of patients have an HLA-identical sibling while the rest are reliant on finding an HLA-compatible unrelated donor. This is particularly difficult for patients from ethnic minorities since the majority of unrelated bone marrow donor volunteers are from Caucasoid ancestry. The London Cord Blood Bank was established to provide an additional source of stem cells for all patients requiring bone marrow transplantation.

Abstract
Released annexin V, an intracellular platelets glycoprotein, was used to determine the cellular injury which occurred during storage of platelet concentrates. Twenty-eight units of leuco-reduced apheresis platelet concentrates, obtained without leucocyte filtration, were analysed. Released annexin V showed a significant correlation with EDTA-induced shape changes of platelet (r = 0.62, P < 0.01) while poor correlation was found between released annexin V and pH or MPV. The combination of released annexin V with dMPV provides excellent markers of the platelet storage lesion for quality monitoring, based on morphological/functional integrities and cellular injury, which are of direct relevance to clinical efficacy of platelet concentrates.

The purpose of this study was to evaluate the impact of a picture archiving and communications system (PACS) on the function and efficiency of a nuclear medicine department at a tertiary care institution. We evaluated 250 consecutive noncardiac nuclear medicine imaging examinations and asked the interpreting physician the following questions: (1) Was PACS used in the interpretation of the study? (2) Did the use of PACS expedite examination completion or aid in study interpretation? And (3) Did the use of PACS permit a definitive diagnosis to be made? PACS was accessed for correlative radiographic images in 155 of the 250 (62%) nuclear medicine examinations. Images available on PACS for review aided in study interpretation in 74% (115 of 155) of cases. The use of PACS was thought to expedite examination completion in 55% (86 of 155) of cases. The system was accessed but not operational in only 1% of cases (2 of 155). PACS provides reliable, rapid access to multimodality correlative radiographic images that aid in the interpretation of nuclear medicine examinations. Such systems also increase the efficiency of a nuclear medicine service by allowing timely and conclusive interpretations to be made.

Abstract
The Haemonetics Multicomponents System (MCS) cell separator allows concurrent donation of red cells in addition to platelets and/or plasma, thus increasing the versatility of apheresis donations. In vivo survival of autologous red cells obtained by MCS was compared with red cells collected conventionally. In this cross-over controlled study, five male volunteers donated one unit of red cells by MCS and one unit of whole blood by the conventional manual method, 3 months apart. After storing donations in SAG-M for 35 days under standard conditions, radioactive (51Cr)-labelled autologous red cells were injected into each donor. The post-transfusion recovery (PTR) of red cells at 24 and 48 h did not show any significant difference between red cells obtained manually and by MCS, indicating that processing differences have no detrimental effects on red cell survival.

Abstract
The severity of hemolytic disease of the fetus or newborn can be assessed with certainty only by measurement of fetal parameters. However, these invasive procedures are not without risk for the fetus. Most erythrocyte antibodies do not cause significant hemolytic disease of the fetus or newborn and various assays are available to assist obstetricians in predicting the likely effect of maternal alloantibodies on fetal erythrocytes. Initially, immunohematologic tests are performed on maternal serum to identify antibodies with a potential for causing hemolytic disease of the fetus or newborn. Antibody concentration is measured by indirect antiglobulin technique titration, or where possible (for anti-D or -c), by quantitation. When used consecutively throughout pregnancy, these tests will reveal a trend that helps to predict the likelihood of hemolytic disease of the fetus or newborn. Functional assays (antibody-dependent cell-mediated cytotoxicity and chemiluminescence) are probably superior to serologic tests for predicting hemolytic disease of the fetus or newborn. Unfortunately, the assays do not reflect accurately the in vivo conditions for a given patient. Knowledge of the immunoglobulin subclass can help to assess the hemolytic potential of maternal antibody, but quantitative measurement of subclasses is still experimental. Diagnostic testing should be approached in a structured manner, commencing with simple serology, followed, in selected cases, by more complex functional assays and indirect fetal tests to identify those fetuses at greatest risk. This approach will enable direct fetal tests to be undertaken only when there is strong suspicion of severe hemolytic disease of the fetus or newborn.

Abstract
A series of already published and unpublished seroepidemiological surveys for toxoplasmosis, carried out in Chile in 1982-1994, is reviewed, expanded and analyzed. The surveys included 76,317 apparently healthy individuals of different ages (0.57% of the country's total population), from 309 urban and rural-periurban localities. Urban groups were integrated by blood donors, delivering mothers and middle grade schoolchildren, while rural-periurban individuals corresponded to unselected family groups. Blood samples were collected in filter paper. The presence of antibodies to Toxoplasma gondii was determined by the indirect hemagglutination test (IHAT), titers > or = 16 were considered positive. The test resulted positive in 28,124 (36.9%) of the surveyed people. Two hundred and six (0.3%) individuals presented IHAT titers > or = 1000, probably corresponding to acute or reactivated infections. A progressive increase of positive IHAT from northern to southern regions of the country was noted, phenomenon probably related to geographical conditions and to a higher production and consumption of different types of meat in the latter regions. It is postulated that ingestion of T gondii cysts by humans is epidemiologically as important as ingestion of oocysts. The result presented stress the epidemiological importance of toxoplasmosis in humans, and warn about eventual implications in immunocompromised patients and in transplacental transmission, organ transplants and transfusions.

Abstract
To establish the incidence and timing of red cell allo-immunisation following transfusion, pretransfusion and serial post-transfusion samples were screened for allo-antibodies in a total of 452 patients who had undergone elective surgery. Antibody screening was performed by 2-stage papain, manual polybrene and indirect antiglobulin techniques (IAT). Red cell allo-antibodies were found in 42 patients and 38 of these (8.4% overall) demonstrated antibodies only after transfusion; 76% of them had Rh specificity. This rate of red cell allo-immunisation is higher than what would be expected if transfused patients were tested only once post-transfusion, as has been the case in several previous studies. For the type of patients studied, this finding may not be of clinical relevance at present because most patients undergoing elective surgery do not require further transfusion in their lifetime. However, this is changing with the longer life expectancy of the population and the increased probability of repeat surgery. Twenty-two (58%) of the antibodies were initially detected by the 2-stage papain and/or polybrene techniques, when the IAT was negative, although later 19 became positive by IAT; this added sensitivity of techniques other than the IAT, to detect early allo-immunisation may be relevant in pretransfusion testing to prevent haemolytic transfusion reactions in patients requiring repeated transfusions.

Abstract
Adrenoleukodystrophy (X-ALD) is a demyelinating disorder characterized by the accumulation of saturated very-long-chain fatty acids (> C22:0) due to the impaired activity of lignoceroyl-CoA ligase. The gene responsible for the disease was found to code for a 84-kDa peroxisomal integral membrane protein. Its amino acid sequence has high homology with the ATP-binding cassette superfamily of transporters and it is predicted to have six membrane-spanning segments and a putative ATP-binding domain. To define the function of ALDP, we studied the topology of its ATP-binding domain by using antibodies (1D6) against a hydrophobic domain (amino acid residues 279 to 482) and antibodies (Abct) against the C-terminal 15-amino-acid hydrophilic domain (amino acid residues 731 to 745) of ALDP. The observation of punctate fluorescence in permeabilized ALD fibroblasts, using Abct antibodies but not with antibodies against catalase, suggests that the C-terminal segment of ALDP is projected toward the cytoplasm from the peroxisomal membrane. Trypsinization of intact peroxisomes under isotonic conditions abolishes the Abct antibody recognition site, whereas the 1D6 antibodies identify a degradation product of 43-kDa protein that has been protected and retained by the membrane. This again suggests that the C-terminal portion of the ALDP protein is located on the outside (cytoplasmic) face of the peroxisomal membrane. Additional support for this conclusion was obtained by purification of the ALDP C-terminal domain, released from purified rat liver peroxisomes incubated with the cytosolic fraction, using blue-Sepharose affinity chromatography. A 47-kDa peptide retained by the column was recognized by Western blot analysis with Abct antibodies against the C-terminal sequence of ALDP and this polypeptide on polyvinylidene difluoride membrane was able to bind [gamma-32P]ATP in vitro in the presence of Mg2+. These results demonstrate that the C-terminal peptide containing the ATP-binding domains of ALDP is on the cytoplasmic surface of the peroxisomal membrane where this domain may function as an ATPase to support the functional role of ALDP in the peroxisomal membrane.

Abstract
BACKGROUND Delayed failure of prosthetic arterial grafts is primarily due to the development of anastomotic intimal hyperplasia. This report follows the proliferation of smooth muscle cells that ensues after prosthetic arterial grafting, using the cyclin-specific antibody MIB-1. METHODS Six-mm expandable polytetrafluoroethylene (ePTFE) grafts were placed end-to-end in the carotid arteries of mongrel dogs. Animals were randomly assigned to sacrifice intervals of 2, 7, 14, and 30 days. Serial coronal sections were cut and immunohistocytochemistry performed using the MIB-1 antibody. RESULTS The control carotid artery had no definable proliferation. Two days after grafting, there was brisk proliferation in the upper one third of the arterial media. By 7 days, proliferation and migration of smooth muscle cells was seen above the internal elastic lamina, in which 50% of the cells were MIB-1 positive. Fourteen days after graft placement, proliferation continued in the neointima; however, the proliferation index was diminished compared with previous time intervals. At 30 days, despite a dramatic increase in lesional increase, there was a marked decrease in the overall proliferation of cells. CONCLUSIONS Following placement of a prosthetic arterial graft, there is initial brisk proliferation of cells in the arterial media, with migration, ongoing proliferation, and resultant development of a localized cellular neointima. Over a 30-day period, the percentage of cells proliferating subsides in contrast to the progressive increase in the size of the neointima. Immunohistocytochemistry with the MIB-1 antibody is a useful tool in defining the cellular kinetics after prosthetic arterial grafting.

Abstract
A sensitive F-cell assay has been used to examine the production of fetal haemoglobin (Hb F) in a group of 77 adult patients with myelodysplastic syndrome (MDS), and a control group composed of 100 normal blood donors. Although the mean F-cell percentage in the MDS group (6.0%) is not statistically different from that in the normal blood donors (3.1%), a higher proportion of myelodysplastic patients have elevated F-cell values and the magnitude of the increases is greater than that observed in blood donors. In order to investigate the association further, the karyotypes of the MDS patients have been examined. 13/21 (61.9%) of the MDS patients with karyotypic abnormalities have F-cell values > 5%, compared to only 6/56 (10.9%) of the MDS patients with a normal karyotype and 11/100 (11%) of the blood donors. The observed difference in the distributions of F cells between the two subgroups of patients with MDS is highly significant (P < 0.0001).
