Abstract
AIM Our study aim is the evaluation of long-term effects of hematopoietic stem cell transplantation on Italian patients with severe Hunter syndrome. METHODS Four boys, suffering from Hunter syndrome, severe phenotype, received hematopoietic stem cell transplantation between 2 years 6 months and 2 years 11 months of age, from 1992 to 2001. A complete multidisciplinary evaluation of hematopoietic stem cell transplantation long-term effects was performed periodically. RESULTS All patients achieved successful engraftment. Urine glycosaminoglycans excretion was reduced or normalized, and the activity of leukocyte iduronate-2-sulphatase enzyme, absent before hematopoietic stem cell transplantation, remained constant, in all patients. Dysostosis multiplex progressed over time, according to the natural evolution of the disease. Joint stiffness improved in all affected districts. Hepatosplenomegaly decreased until it disappeared. The cardiovascular involvement stayed unchanged, as well as hearing loss. Skin became hyperelastical; face features seemed less coarse if compared to the natural evolution of the disease. Cerebral white matter alterations were constant in time. On the contrary, the hematopoietic stem cell transplantation did not prove to have long-term effectiveness on neurological symptoms of Hunter syndrome. CONCLUSION The hematopoietic stem cell transplantation was successful in slowing the progression of Hunter syndrome, and even the evolution of neurological feature of the disease was slower in the first years after this treatment.

Abstract
The sedative and anxiolytic potential of Leea indica (Burm. f.) Merr., a Bangladeshi tribal medicinal plant was studied for the first time. The crude methanol extract of L. indica leaves was evaluated for its central nervous system (CNS) depressant effect using rodent behavioral models, such as hole cross, open field and thiopental sodium induced sleeping time tests for its sedative properties and an elevated plus-maze (EPM) test for its anxiolytic potential, respectively. The methanol extract of L. indica at doses of 200 mg/kg, p.o. and 400 mg/kg, p.o., displayed a dose dependent suppression of motor activity, exploratory behavior (in hole cross and open field tests) and prolongation of thiopental induced sleeping time in mice; the highest CNS depressant effect was shown at a dose of 400 mg/kg, p.o. In the EPM test, both dose of methanol extract significantly (p < 0.01) increased exploration to and time spent by the treated mice in EPM open arms in a dose dependent manner. These results provide in vivo evidence that leaves of L. indica in general have significant sedative and anxiolytic effects. However, these results may rationalize the scientific basis for use of this plant in traditional medicine for treatment of anxiety and related disorders.

Abstract
The paper describes differential tolerance of two fresh water crustaceans Mesocyclops hyalinus and Allodiaptomus satanus to 60Co gamma radiation. Mesocyclops hyalinus is dominant species at site 1, near a Thermal Power Plant at Kolaghat East Midnapore where fly ash deposition is a regular phenomenon. Allodiaptomus satanus is dominant species at site 2 at Kolkata, Ballygung where anthroponotic activities are more pronounced. M. hyalinus is naturally exposed to more stressful situation than A. satanus as revealed by comparing the hydrological parameters of the two habitats. Experimental exposure to ionizing radiation resulted in differential changes in viability morphology and antioxidant enzyme activities in the two selected species. Survival experiments showed greater tolerance of M. hyalinus compared to A. satanus up to 8Gy (absorbed dose) after which if showed drastic fail in survival. More pronounced morphological changes were observed in A. satanus as compared to that in M. hyalinus. The pattern of changes in antioxidant enzyme activity is distinctly opposite in the two radiation exposed species. While in M. hyalinus stimulation in activity of both CAT (excepting at 10Gy absorbed dose) and SOD was observed A. satanus showed decrease in activity of both the enzymes when compared to their unirradiated counterparts.

Abstract
Formal observation in psychiatric settings is a widely accepted intervention employed by psychiatric nurses to reduce the incidence of adverse patient outcomes such as suicides, self-harm, violence and elopements in the psychiatric population. Formal observation includes general or routine observation, observation every 15 or 30 min, continuous or constant observation, and one-to-one observation. While formal observation consumes nursing resources, the efficacy of formal observation in reducing patient risk and providing therapeutic benefit remains unclear. To date, no randomized controlled studies exist. The existing qualitative research fails to demonstrate a direct correlation between the act of formal observation and the prevention of adverse patient outcomes. Common in the literature is a debate as to whether formal observation or therapeutic engagement is more beneficial. This paper, therefore, identifies gaps in the research and synthesizes relevant research regarding the effectiveness of formal observation in preventing adverse outcomes like suicides, self-harm, violence and elopements.

Abstract
We study the linear stability of an air front pushing on a viscoelastic upper convected Mawxell fluid inside a Hele-Shaw cell. Both theory and experiments involving several viscoelastic fluids prove that a unique dimensionless time parameter lambda[over] controls all elastic effects. For small values of lambda[over], Newtonian behavior dominates, while for higher values of lambda[over] viscoelastic effects appear. We show that the linear growth rate of a small initial perturbation diverges for a critical value lambda[over]=lambda(c)[over] approximately 10. Experiments prove that this divergence is associated to a fracturelike pattern instability of the interface. We conclude that the observed fractures come from the Saffman-Taylor instability and that they directly emerge from the linear regime of it.

Abstract
We discuss the propagation of nonlinear electromagnetic short waves in a magnetically saturated ferromagnetic thick film. The sample is magnetized to saturation by a field perpendicular to both the film plane and the propagation direction. A (2+1) dimensional asymptotic model equation generalizing the sine-Gordon one is derived. Line soliton solutions are exhibited; their stability condition is derived. When unstable, line solitons decay into stable two-dimensional lumps, which are studied both numerically and analytically.

Abstract
We study theoretically the linear Saffman-Taylor instability for non-Newtonian fluids in a Hele-Shaw cell. After introducing the notion of generalized Newtonian fluid we calculate the associated Darcy's law. We derive the relation governing the growth rate of normal modes for a large class of non-Newtonian flows. For shear-thinning fluids at high shear rate our theory provides Darcy's laws free of the nonphysical divergences appearing in the classical approaches. We characterize fluids which develop instabilities faster than Newtonian fluids under the same hydrodynamical conditions. Another primary result that this paper provides is that for some shear-thickening fluids, all normal modes are stable.

Abstract
The propagation of bulk polaritons in ferromagnetic slab is considered through a short-wavelength approximation. Neither the damping nor the demagnetizing field do affect essentially the propagation and stability of the line soliton. The stable line soliton may be destroyed by background instability: the latter is suppressed in a narrow strip. The unstable line soliton decays into lumps, which can be described both numerically and through a variational approach. Lump interactions are mentioned.

Abstract
This paper describes the design and implementation of a Cyber Medical Center (CMC) using web technology. The intention is to overcome the inefficiency of the traditional filing system for patients' medical records, which are considered to be time and space consuming. Another objective is to enhance the interaction between the user - the patient in this case - and the medical center personnel - the doctors and staff. This task is achieved by developing a cyber medical center interfaced with the Internet to provide direct public access. The traditional filing system is replaced by a database system for maintaining the electronic medical records of all patients in the medical center. The doctors or staff can either view the medical records or update them through the Intranet/Internet. This system has been successfully developed, implemented and tested on the Intranet platform. It will be available in a university medical center for practical use.

Abstract
From April 1981 to February 2000, 105 patients with chronic myeloid leukemia (CML) underwent BMT from HLA-identical related donors at a single center. Eighty-eight patients were in chronic phase (CP), 11 patients in accelerated phase and six patients in blast crisis. Ten of these patients received a second BMT (BMT2). Comparison of BMT in CP with chemotherapy and/or alpha-IFN (n=70) was also made. Patients were given cyclophosphamide (CY) and single-dose TBI (CYTBI, n=38) or busulfan (BU) and CY (BUCY, n=67). Overall 54 patients are alive and 52 of them are disease-free with a median follow-up of 11.3 (range 1.1-19.4) years. Ten-year disease-free survival (DFS) in CP patients was better after BUCY, 61% (95% CI, 47-68%) than after CYTBI, 41% (95% CI, 23-61%) (P=0.07). For 88 patients who received a transplant in CP, results were significantly improved when BMT was performed within 1 year after diagnosis (P=0.02) or at an age < or = 25 years old (P=0.01). Ten-year survival in patients who received BMT in CP was better than in patients treated with chemotherapy (56% vs 10%; P=0.0001) or alpha-IFN-based treatment (33%; P=0.09) with survival curves crossing at 4.2 years and at 4 years, respectively. The probability of DFS after BMT2 was 60% (95% CI, 26-87%). CP patients who received BMT after CYTBI had a higher probability of relapse and transplant-related mortality than patients receiving BUCY (53% and 58% vs 9% and 34%; P=0.002 and P=0.08, respectively). All but six patients are currently on no medication and have resumed all activities without any limitation. These long-term results confirm that allogeneic BMT is the only curative approach for CML patients and should be offered to all patients with a suitable donor as soon after diagnosis as possible.

Abstract
A growing body of evidence suggests an important contribution of the cellular actions of thrombin to thrombosis and restenosis following angioplasty. Recently we reported on SCH 79797 (N3-cyclopropyl-7-¿[4-(1-methylethyl)phenyl]methyl¿-7H-pyrrolo[3, 2-f]quinazoline-1,3-diamine) and its analogs as new potent, nonpeptide thrombin receptor antagonists. This study further characterizes the biochemical and pharmacological actions of pyrroloquinazoline inhibitors of protease activated receptor-1 (PAR-1) in human platelets and coronary artery smooth muscle cells (hCASMC). SCH 79797 and its N-methyl analog (SCH 203099) inhibited binding of a high-affinity thrombin receptor-activating peptide ([(3)H]haTRAP, Ala-Phe(p-F)-Arg-ChA-HArg-[(3)H]Tyr-NH(2)) to PAR-1 with IC(50) values of 70 and 45 nM, respectively. SCH 79797 inhibited [(3)H]haTRAP binding in a competitive manner. SCH 79797 and SCH 203099 inhibited alpha-thrombin- and haTRAP-induced aggregation of human platelets, but did not inhibit human platelet aggregation induced by the tethered ligand agonist for protease-activated receptor-4 (PAR-4), gamma-thrombin, ADP, or collagen. SCH 203099 inhibited surface expression of P-selectin induced by haTRAP and thrombin, and it did not increase P-selectin expression or prevent thrombin cleavage of the receptor. Thrombin and TFLLRNPNDK-NH(2) (TK), a PAR-1-selective agonist, produced transient increases in cytosolic free Ca(2+) concentration ([Ca(2+)](i)) in hCASMC. This increase in [Ca(2+)](i) was inhibited effectively by SCH 79797. However, the Ca(2+) transients induced by SLIGKV-NH(2,) a PAR-2-selective agonist, were not inhibited by SCH 79797. Thrombin- and TK-stimulated [(3)H]thymidine incorporation also was inhibited completely by SCH 79797. The results of this study demonstrate that SCH 79797 and SCH 203099 are potent, selective antagonists of PAR-1 in human platelets and hCASMC. These data also suggest that the thrombin stimulation of Ca(2+) transients and mitogenesis in hCASMC is mediated primarily through activation of PAR-1.

Abstract
Twenty-six transplanted thalassemic patients out of 295 analyzed, showed the presence of persistent mixed chimerism, over a period of time varying between 2 and 11 years after BMT. Despite the presence of large numbers of residual host cells, these transplanted thalassemic patients no longer require red blood cell transfusions and have a functional graft, producing sufficient levels of hemoglobin A ranging from 8.3-14.7 g/dl. These ex-thalassemic patients with persistent mixed chimerism, although they did not achieve complete donor engraftment are no longer exposed to the risk of graft rejection. The mechanisms underlying this apparent state of tolerance or education in these patients are at the present time unknown. However, these observations may be useful for physicians involved in defining optimal strategies for clinical gene therapy, in utero hematopoietic stem cell transplantation and adoption of less toxic conditioning regimens in mini-transplantation.

Abstract
Bone marrow transplantation (BMT) from an HLA-identical donor is an established therapy to cure homozygous beta-thalassemia. Approximately 10% of thalassemic patients developed a persistent mixed chimerism (PMC) after BMT characterized by stable coexistence of host and donor cells in all hematopoietic compartments. Interestingly, in the erythrocytic lineage, close to normal levels of hemoglobin can be observed in the absence of complete donor engraftment. In the lymphocytic lineage, the striking feature is the coexistence of immune cells. This implies a state of tolerance or anergy, raising the issue of immunocompetence of the host. To understand the state of the T cells in PMC, repertoire analysis and functional studies were performed on cells from 3 ex-thalassemics. Repertoire analysis showed a profound skewing. This was due to an expansion of some T cells and not to a collapse of the repertoire, because phytohemagglutinin stimulation showed the presence of a complex repertoire. The immunocompetence of the chimeric immune systems was further established by showing responses to alloantigens and recall antigens in vitro. Both host and donor lymphocytes were observed in the cultures. These data suggest that the expanded T cells play a role in specific tolerance while allowing a normal immune status in these patients.

Abstract
A series of pyrroloquinazolines has been discovered that represent novel small molecule inhibitors of the intramolecular ligand of the thrombin receptor. Analogs were prepared to study the structure-activity relationships of substitution at the N 1, N3, and N7 positions of the heterocycle. Compounds 4e and 4f have been identified with IC50's of 56 and 52 nM, respectively.

Abstract
Tetracyclic guanines have been shown to be potent and selective inhibitors of the cGMP-hydrolyzing enzymes PDE1 and PDE5. In general, these compounds are inactive or only weakly active as inhibitors of PDE3, which is a major isozyme involved in cAMP hydrolysis. Structure-activity relationships are developed at N-1, C-2, N-3, and N-5 on the core nucleus. Compound 31, with an IC50 of 70 pM, is the most potent inhibitor of PDE1, while 50, with an IC50 of 4 nM, is the most potent inhibitor of PDE5. Compounds 20, 22, 30, and 50 are potent dual inhibitors with IC50 values below 30 nM for both PDE1 and PDE5. Compounds 12, 20, and 28 reduced blood pressure by more than 45 mmHg when administered orally at 10 mg/kg to the spontaneously hypertensive rat (SHR).

Abstract
BACKGROUND The aim of the study was to give guidelines for the management of a pulmonary rehabilitation program in patients affected by COPD. MATERIALS AND METHODS 52 patients affected by COPD with chronic respiratory failure and hypoxemia have been evaluated. All patients underwent a personalized rehabilitation program joining traditional technics of rehabilitation and an exercise training. The study was divided into three different phases: traditional pulmonary rehabilitation; exercise training by treadmill; home care rehabilitation. In order to follow-up the outcome of the patients, the 12 minutes walking test and the pulmonary function tests were used. RESULTS The study showed clearly an improvement of fitness of the patients after exercise training These results were confirmed after one year follow-up. CONCLUSIONS In conclusion, in the light of these results, the exercise training and, overall, the home care rehabilitation, acquire an important role in the management of patients affected by COPD.

Abstract
Lung cancer is a worldwide problem and in many countires it is the most lethal malignancy. Because relapse is frequent after resection of non small cell lung cancer, an urgent need exists to define prognostic factors which could help in choosing the best therapeutic approach. We performed immunohistochemistry on 60 formalin-fixed paraffin-embedded non small cell lung cancer specimens in order to evaluate the frequency of cyclin D1 overexpression, and to relate it to the degree of malignancy of these tumors and to the overall survival time of the patients. All specimens were positive for cyclin D1 immunostaining. We found cyclin D1 overexpression in 30 (50%) of our specimens, with no significant difference among the different histological types. Cyclin D1 overexpression correlates in a statistical manner with short-term patient survival. Mantel-Cox analysis of these data generated a significant P value = 0.003. The mean survival time and the five-year survival rate also differed statistically. We did not find any statistically significant correlation between cyclin D1 overexpression and histological grading, tumor stage or TNM status. We concluded that cyclin D1 overexpression in 30 patients is a frequent event in non small cell lung cancer pathogenesis and may have prognostic relevance.

Abstract
A DRB1*1503 allele not associated with DRB5 locus has been detected in an African family during routine HLA typing for bone marrow transplantation. PCR/SSOP analysis showed the DR2-associated alleles in all the family members but the DRB5 locus appeared to be absent in the patient and his brother. The samples were then analyzed for the presence of DRB6 pseudogenes and we found that the unusual haplotype was associated with DRB6*0101 allele. This finding strengthen the hypothesis of a recombination hot spot between DRB1 and DRB6 genes.

Abstract
A new methodology for the construction of combinatorial libraries is described. The approach, termed dendrimer-supported combinatorial chemistry (DCC), centers on the use of dendrimers as soluble supports. Salient features of DCC include solution phase chemistry, homogeneous purification, routine characterization of intermediates, and high support loadings. To demonstrate the feasibility of DCC, single compounds and a small combinatorial library were prepared via the Fischer indole synthesis. Excellent product yields and purities were obtained, and dendrimer-protected intermediates could be routinely analyzed by 1H and 13C NMR and by mass spectrometry. The results indicate that DCC is a general and efficient strategy for the generation of combinatorial libraries.

Abstract
Molecular genetic techniques permit sensitive assessment of host hematopoiesis after marrow transplantation for thalassemia. Information on this persistence and the cell lines in which it occurs may permit therapeutic intervention in patients at high risk for rejection and/or relapse. The objective of this study, therefore, was to determine the evolution and cell line distribution of persistent mixed chimerism detected in 55 patients treated for beta thalassemia. Our findings indicated that rejection occurred in 20 patients, the host component disappeared in 20, and mixed chimerism without transfusion need persisted for 1 to 7 years in 15. In three patients with stable mixed chimerism for 4, 5, and 7 years, host hematopoiesis fluctuated between 25% and 75%. Despite this, donor pattern beta-globin chain synthesis maintained hemoglobin levels between 10 and 13.5 g/dL without transfusion. In these three patients, the polymerase chain reaction of the VNTR and the fluorescent in situ hybridization analysis revealed the coexistence of donor and host cells in the different peripheral blood cell subpopulations and precursors studied (CD2+, CD4+, CD8+, and CD19+ granulocytes; glycophorin-A+, erythroid burst-forming units, CD33+, granulocyte-macrophage colony-forming units). We found that rejection and disease recurrence occur in approximately one third of patients with early mixed chimerism. High levels of host type hematopoiesis can be present in patients not requiring transfusion.

Abstract
Thalassemia patients can be categorized as class 1 (minimal liver damage and iron overload), class 3 (extensive liver damage from iron overload), and class 2 (intermediate). These categories are prognostic for treatment outcome after marrow transplantation. Class 3 patients have more transplant-related mortality than other patients. This study examines transplantation outcome for class 3 patients. Records were reviewed of 215 patients in class 3 who received transplants in Pesaro from HLA-identical related donors between May 1, 1984 and May 1, 1994. The influence of pretransplant, peritransplant, and posttransplant variables on survival, relapse, and transplant-related mortality was examined by product-limit and proportional-hazards multivariate analysis. Age and conditioning regimen were influential on survival, and regimens with less than 200 mg/kg cyclosporine (CY) were associated with 5-year survival probabilities of .74 and .63 patients younger than 17 years and older patients, respectively. Transfusion history and regimen were influential on rejection with 5 year probabilities of .53 and .24 in patients who received less than or greater than 100 red blood cell transfusions before transplantation and regimens containing less than 200 mg/kg CY. Results of transplantation for patients with advanced thalassemia treatment have improved with the introduction of conditioning regimens with less CY. This has been associated with an increase in rejection (particularly in patients who have received < 100 red blood cell transfusions before transplant). Efforts at reducing the rejection rate by modifying the conditioning regimen should be concentrated on younger patients who have received a small number of transfusions. Patients with thalassemia who have HLA-identical family members should be transplanted before they are in class 3.

Abstract
In this study, three WHO recommended reference strains of Leishmania donovani (DD8), L. tropica (K27) and L. major (5 ASKH) were compared by isozyme analysis of 9 soluble enzymes using cellulose acetate electrophoresis (CAE). The isozyme profile of the three species showed distinct electrophoretic mobilities of the enzymes studied. This technique was applied to study the enzyme patterns of 8 clinical isolates of visceral leishmaniasis (VL) and two post kala-azar dermal leishmaniasis (PKDL) collected from the present epidemic (1990s to date). They were seen to be similar to the two isolates of the 1970s epidemic. Interspecies differences were observed in different reference Leishmania species whereas no intraspecies difference was observed amongst the clinical isolates (8VL + 2PKDL) and all of these were found to be similar to L. donovani isolates of 1970s epidemic.

Abstract
Seventy-four patients with homozygous beta-thalassemia who underwent allogeneic bone marrow transplantation (BMT) were analysed in order to evaluate the incidence and the significance of mixed chimerism (MC). Using a panel of four single locus specific minisatellite DNA probes, MC was found in 36.5%, 34.7% and 16.7% of the patients at 2, 6 and 12 months respectively after BMT. Moreover we found that different pretransplant conditioning regimens could be responsible for variations in the incidence of MC. The level of residual host cells found 2 months after BMT correlated with the occurrence of rejection.

Abstract
BACKGROUND In this work we investigated whether serologically HLA class II compatible donor-recipient pairs showed differences in restriction fragment length patterns, and whether there is a correlation between the genomic differences observed and the incidence of rejection and acute graft versus host disease (GVHD). METHODS High molecular weight DNA was extracted from thirty-three transplanted thalassemic patients and from their genotypically HLA identical donors. The DNA was digested with TaqI and PstI restriction enzymes, separated by horizontal electrophoresis and transferred onto nylon filters. RESULTS Differences at the molecular level were observed in only one patient, who rejected the transplant respect to his donor when DNA was digested with the TaqI restriction enzyme and hybridized with DPB cDNA probe. CONCLUSIONS Although the molecular analysis revealed a difference between a patient who rejected the transplant and his donor, the RFLP typing confirmed the serological identity of the HLA class II antigens in all the other donor-recipient pairs studied.

Abstract
30 patients with homozygous beta-thalassaemia aged 6 months to 7 years received allogeneic marrow transplants following busulphan (Bu) and cyclophosphamide (Cy). Post-transplant immunosuppression was with methotrexate (MTX) or MTX and Cy. The first 6 patients received 16 mg/kg Bu and 200 mg/kg Cy. 3 died of transplant-related complications and 3 survived without thalassaemia 701-762 days after transplantation. The subsequent 24 patients received 14 mg/kg Bu and 200 mg/kg Cy. 1 died on day 28 without engraftment and 23 survived 64-624 days after transplantation. 19 of the 23 surviving patients are without thalassaemia while 4 patients with initial engraftment became thalassaemic again in 32-46 days and survived 253-624 days after transplantation. The latest death was 50 days after transplantation. The probability of developing grade 2 or greater acute graft versus host disease (GVHD) in patients with sustained engraftment was 23%. 5 patients had chronic GVHD which is still active and causing disability in 3 patients 358, 456, and 477 days after transplantation. The actuarial survival was 86% and the actuarial disease-free survival was 73%.

Abstract
Thirteen patients with homozygous beta thalassemia underwent allogeneic marrow transplantation from sibling donors, 12 of whom were heterozygous for beta thalassemia. Six patients were transplanted in an advanced stage of their disease while seven were transplanted early in their disease course. Donors and recipients were genotypically identical for the HLA-A, -B and -D loci in 11 cases and mismatched for the D locus in two. A variety of preparative regimens was utilized involving high doses of busulphan (Bu) and/or cyclophosphamide (CY) and/or total body irradiation (TBI). Failure of engraftment or autologous hematologic recovery after transient engraftment was seen after intensive preparative regimens including: CY 200 mg/kg and 800 rad of TBI; Bu 8 mg/kg and CY 200 mg/kg; and Bu 8 mg/kg, CY 200 mg/kg, and 300 rad of TBI. A regimen of Bu 16 mg/kg, CY 200 mg/kg, and 400 rad of TBI resulted in deaths from transplant-related causes in the three patients treated with this regimen. Seven of the 13 patients are surviving 363-665 days after transplant. Five of the seven failed to achieve engraftment or had autologous reconstitution after transient engraftment. Five of the six deaths were transplant related, and one patient died of cardiac failure one year after an unsuccessful transplant attempt. Two patients are surviving with engraftment and without thalassemia major 363 and 491 days after transplantation. Both of these patients were transplanted early in their disease course.

Abstract
The CFU-Gm content of liver, spleen and bone marrow of human fetuses was determined from the 8th to 28th week of gestational age. The study of progenitor cells from 43 fetal livers revealed that the CFU-Gm increased from 8 to 12 weeks, was relatively stable through 16 weeks and thereafter declined by 22 to 24 weeks. The total number of liver CFU-Gm rose from 10(4) to greater than 10(6) CFU-Gm by the 16th week of gestation and declined to approximately 4 X 10(5) progenitor cells by 22 to 24 weeks. Peak values of bone marrow CFU-Gm were noted at 10 to 14 weeks of gestation. Generally, the numbers of these progenitor cells declined by 16 to 18 weeks; however, several high values were obtained at later times. Splenic CFU-Gm were relatively constant in number between 12 and 28 weeks of gestation with no correlation with fetal age. Thus, these studies indicate that certain fetal tissues contain substantial numbers of hemopoietic progenitor cells. Based on the quantity of CFU-Gm obtained, it appears feasible to use fetal liver cells as a source of progenitor cells for transplantation.

Abstract
2 patients with acute leukaemia in relapse were transplanted with fetal liver cells following a conditioning regimen of cyclophosphamide (120 mg/kg) and total body irradiation (1000 r). Each patient achieved a remission with haematopoietic recovery that was rapid in one case and delayed in the other. In one case there was evidence of chimerism as demonstrated by the presence of the XYY karyotype of the donor fetus in 20% of marrow metaphases, by the presence of double Y bodies in the peripheral blood, by the appearance of new HLA-antigens, and by red cell isoenzyme phenotypes of donor origin. In the second case there was prompt haematopoietic recovery and the appearance of red cell isoenzyme phenotype of donor origin. Survival was 153 and 30 d, respectively, and both patients died of interstitial pneumonia without evidence of graft versus host disease.

Abstract
This study investigates the effect of fetal liver transplantation in reconstituting hemopoiesis in supralethally irradiated rats. Different cell doses of fetuses at the embryonic age of 15 and 18 days were compared to equivalent cell doses of adult bone marrow cells. Although the frequency of engraftment ranged between 75 and 100% in all the groups of animals studied, the survival rate at 30 days after TBI did not show any significant difference between the fetal liver and the bone marrow treated recipients. The bone marrow transplants performed in littermate rats almost doubled the percentage of survivors at 30 days and showed a cell dose relationship suggesting that, in the closed colony of random-bred rats used, the mortality after bone marrow and fetal liver transplants was mainly due to graft-versus-host-disease. Antibiotic prophylaxis and treatment during the experiment did not modify the results in a separate group of fetal liver and bone marrow transplanted rats. In the rat model system used in this set of experiments fetal liver did not reveal any advantage over bone marrow transplantation.
