Differentiating mesenchymal cells and the extracellular matrix that these cells produce constitute the structural basis for developing organs. The splanchnopleuric mesenchyme surrounding the developing gut and respiratory tubes provides connective tissue cells to the lamina propria/submucosa and smooth muscle cells to the muscularis musosae/muscularis externa. In human fetal intestine, the identity of the matrix-producing cell or cells has begun to be elucidated. The smooth muscle cell is one of the sources of collagen fibers in the extracellular matrix in the developing human fetal intestine and collagen production is a significant function of smooth muscle cells during intestinal organogenesis. The aim of the current study was the quantitative investigation of collagen production by human fetal intestinal smooth muscle cells in various stages of development (10 to 23 weeks of gestational age). Identification of the mesenchymal cells/extracellular matrix was confirmed by immunohistochemical techniques using the following monoclonal antibodies: actin, desmin, vimentin, collagen IV and fibronectin. Histochemical stains for the presence of extracellular matrix components were also performed. Immunohistochemical analysis and the results of the histochemistry of the fetal human intestine in various stages of development revealed that the muscle cells of the muscularis externa contribute to the production of collagen in collaboration with the mesenchymal cells. This is more evident between 10 to 14 weeks of gestational age. 相似文献

The most common single genetic disorder and a major public health issue in Greece and other Mediterranean countries is beta-thalassemia. Current therapeutic approaches for homozygous beta-thalassemia entail blood transfusions and iron chelation therapy with deferoxamine or deferiprone for preventing tissue hemosiderosis. Recently, much effort has focused on various inducers of fetal hemoglobin (HbF) such as recombinant human erythropoietin (rHuEPO), especially in beta-thalassemia intermedia. Ten adult patients, 5 with beta-thalassemia major and 5 with beta-thalassemia intermedia, received 150 IU/kg rHuEPO (epoetin-alpha) subcutaneously three times a week. Seven patients were transfused every 14-30 days and 3 with beta-thalassemia intermedia were only occasionally transfused. The minimum duration of treatment was 12 weeks in order to define if there was any response. Transfusion intervals were modified according to the rHuEPO response to maintain stable Hb values. Lower transfusion requirements were observed in 5 patients after rHuEPO treatment (p = 0.028). In the 3 non-transfused patients, Hb values increased, and the patients are still being treated and followed up for a period ranging from 14 weeks to 2 years. Two patients with thalassemia major discontinued treatment after 12 weeks, as they did not achieve any response regarding transfusion requirements or Hb values. Pretreatment serum transferrin receptor levels were higher than in controls (p < 0.001) and significantly increased following rHuEPO treatment (p = 0.027). Patients had higher serum endothelin-3, sICAM-1 and sE-selectin values before rHuEPO treatment compared to controls (p < 0.001, p < 0.001 and p = 0.016, respectively), but these values were not altered during treatment. HbF values presented a slight, non-significant increase. rHuEPO treatment has a beneficial effect in transfusion-dependent beta-thalassemia patients. Although a slight increase in HbF levels was observed, other possible mechanisms are probably involved. None of our patients experienced thrombotic complications and a rise in blood pressure. 相似文献

Peak expiratory flow rate (PEFR) and standing height (Ht) were measured in 522 healthy Greek children aged 7–16 years. The regression equation of PEFR on height in centimetres was PEFR=5.34 Ht-380.8. This demonstrated markedly higher values for PEFR in Greek children compared to previously published data from other countries. A sample of 339 British children was examined similarly. The regression equation of PEFR on height in centimetres was PEFR=5.64 Ht-472.5. This was similar to previously published data. No cause for this discrepancy was found after close examination of population sampling, measurement error or calibration error in the Greek study. It is therefore concluded that Greek children appear to have an unexpectedly high PEFR for height. 相似文献

BACKGROUND: Aim of our study was to evaluate the efficacy of multiagent intensive preoperative chemotherapy in patients with Ewing sarcoma family tumors (ESFT), in order to succeed a better percentage of necrosis before surgical resection. PROCEDURE: Eighteen patients with ESFT were treated with the same multiagent intensive preoperative protocol. 5/18 patients had bone Ewings sarcoma (EWS) and 13/18 had peripheral primitive neuroectodermal tumor (PNET). None had metastases at diagnosis. Chemotherapy consisted of 5 or 6 cycles with vincristine, cisplatin, cyclophosphamide, and Adriamycin, followed by 12 cycles of vincristine, cyclophosphamide, and actinomycin-D. Five patients with EWS underwent total resection after 5-6 cycles of preoperative chemotherapy and prosthetic replacement was performed in two of them. In 3/13 patients with PNET the tumor was resected at diagnosis and in 1/13 after 5 cycles of chemotherapy, while 9/13 patients received chemotherapy only and/or radiotherapy. RESULTS: In patients with EWS, the histologic specimens of the resected tumors showed that tissue necrosis was 100% in four patients and 95% in one patient. The good histologic response reflects the effectiveness of this regimen in all ESFT. No patient had topical recurrence or developed metastatic disease during follow-up period (2-13 years, mean time 7.4 years). All patients had the scheduled cycles without delays or dose reductions. There were no major side effects of chemotherapy. CONCLUSIONS: The intensive chemotherapy schedule, comprising of 5-6 cycles preoperatively, seems to maximize the percentage of tumor necrosis, thus improving outcome. Our study implies that this combined therapy may improve the prognosis of ESFT. 相似文献

PURPOSE: We sought to investigate contrast sensitivity on the fellow eyes of amblyopic and successfully treated amblyopic subjects. METHODS: Contrast sensitivity was tested monocularly on both eyes of 48 amblyopic patients (mean age, 11.51 years) and of 22 successfully treated amblyopic subjects (visual acuity 20/20 in each eye; mean age, 11.22 years). Inclusion criteria were visual acuity in the amblyopic eye 20/40 or better (mild amblyopia) and 20/20 or better in the fellow eye, steady fixation, no signs of congenital, latent or manifest/latent nystagmus on clinical examination. Twenty normal subjects (20 eyes) were used as age-matched controls. RESULTS: Contrast sensitivity functions from the fellow eye of the 48 amblyopic patients, even those who had never been treated with occlusion therapy before, were significantly decreased (P < 0.001) compared with control subjects. Both the previously amblyopic and the fellow eye of the 22 "cured" amblyopic subjects demonstrated significantly lower values (P < 0.001) compared with control patients. CONCLUSIONS: We suggest that the nonamblyopic, "normal" eye of amblyopic patients behaves abnormally when evaluated for contrast sensitivity functions. Neither the previously amblyopic nor the fellow eyes of successfully treated subjects were comparable with controls. Occlusion therapy may not be implicated for depressed contrast sensitivity of the fellow eye in amblyopia. The assessment of contrast sensitivity can provide important information on the visual function and the influence of occlusion therapy in amblyopia. 相似文献

Abstract The seroepidemiology of hepatitis B in children living in Greece 6 years post-implementation of universal infant immunization
(1998) was studied. We collected 90–100 sera/year of age, stratified by geographic region. The prevalence of HbsAg(+) was
0.6% (95% CI 0.3–1.3) whereas 4.5% (95% CI 3.4–5.9%) of children over 12 months of age had evidence of past HBV infection.
A significant decline in the prevalence of past infection between children born before and after 1998 (5.5% vs 2.9%; RR =
1.9, 95% CI 1.03–3.5) was noted. Conversely, the prevalence of past HBV infection did not change significantly among immigrant
children. Reinforcement of early vaccination of immigrant population is necessary. 相似文献
