Localization of eosinophil granule major basic protein by immunofluores-cence permits recognition of both eosinophil infiltration and degranulation. Over the past decade and a half, our laboratory has shown that eosinophil infiltration and degranulation occur in many diseased tissues in humans; among normal tissues studied as controls, only the gut showed striking eosinophil infiltration and degranulation. Using an indirect immunofluores-cence procedure for the detection of major basic protein, we extended our analyses of normal human tissues to include tissues from essentially all body organs; a total of 117 biopsy/autopsy specimens were analyzed. To determine whether the method of tissue procurement affected the level of eosinophil degranulation in the normal gastrointestinal tract, normal proximal jejunum from six patients was biopsied using either an endoscopic forceps or a scalpel at the time of elective surgery and examined by immunofluorescence. Spleen, lymph node, and thymus tissues showed eosinophil infiltration with scant evidence of degranulation, but the only organ showing both eosinophil infiltration and remarkable degranulation was the gastrointestinal tract. Eosinophil degranu-lation was significantly increased in specimens obtained by endoscopic forceps compared to those obtained by scalpel (P 0.021). These results indicate that tissue procurement methods affect the degree of eosinophil degranulation in the gut. Thus, among normal human body organs, both eosinophil infiltration and appreciable degranulation consistently occur only in the gut. Anat.
Background: Kangaroo care (KC) has been widely using to improve the care of low birth weight infants. However, very little is known about cerebral hemodynamics responses in low birth weight infants during KC intervention. The objective of this study was to elucidate the response of cerebral hemodynamics during KC in low birth weight infants.
Background: Biological rhythmicity, particularly circadian rhythmicity, is considered to be a key mechanism in the maintenance of physiological function. Very little is known, however, about biological rhythmicity pattern in preterm and term neonates in neonatal intensive care units (NICU). In this study, we investigated whether term and preterm neonates admitted to NICU exhibit biological rhythmicity during the neonatal period.
Summary:Case reportA 4-year-old boy was first noted to have severe anemia at A 4-year-old boy with Diamond-Blackfan anemia and a history of multiple transfusions underwent umbilical 1 month of age. An evaluation showed hemoglobin 50 g/l, white blood cell count 5.5 × 10 9 /l with normal distribution, cord blood transplantation from his HLA-identical female sibling born by vaginal delivery at 38 weeks. The platelet count 385 × 10 9 /l, and 0% reticulocyte. The bone marrow showed marked erythroid hypoplasia with no patient was prepared with busulfan, cyclophosphamide and antilymphocyte globulin. Methotrexate and cycloabnormal cells and a diagnosis of Diamond-Blackfan anemia was confirmed. He was 2680 g at birth, the product sporin A were given for the prophylaxis of GVHD. Regimen-related toxicity was not observed and successful of a full-term, uncomplicated gestation. The parents were healthy and there was no consanguinity or family history engraftment occurred, including the erythroid series. No evidence of acute or chronic GVHD has been of hematological disorders. Several therapeutic approaches including intravenous high-dose methylprednisolone and observed for 14 months after transplantation. This is the first case of successful umbilical cord blood transoral corticosteroids had been tried. However, they had only a transient effect on the progressive anemia, and the patient plantation to a patient with Diamond-Blackfan anemia. Keywords: cord blood transplantation; Diamondbecame steroid-resistant and transfusion-dependent. He received 60 units of filtered and irradiated packed red cells Blackfan anemia; childhood; hemosiderosis before transplantation without any iron-chelating therapy. His HLA-type was A24, 31; B51, 52; DR15(2), 4; DQ1, 4, and not identical to the parents and a sibling (father: Diamond-Blackfan anemia is a disorder of childhood A31, 33; B44, 52; DR15(2), 8; DQ1, mother: A24, 33; B44, characterized by normochromic-macrocytic anemia, reti-51; DR4, 13; DQ1, 4, brother: A31, 33; B44, 52). culocytopenia and a normocellular marrow with a selective At 3 years of age, he displayed signs of iron overload deficiency of erythroid progenitors. Most patients respond including elevations of serum transaminase, iron and ferrito corticosteroids initially. However, about 60% require tin. CT scan showed a marked increase in the density of chronic red cell transfusion and die in the second and third the liver parenchyma, which was consistent with liver decade of life as a result of hemosiderosis. 1 Allogeneic hemosiderosis.
