During the five-year period 1964-68 96 733 births were registered in the 28 hospitals equipped with maternity facilities in the Uppsala hospital region. Of these babies, 1 636 were born in 818 twin deliveries. Data on gestational age, sex, weight and length at birth, birth order, hospital type, congenital malformations and perinatal mortality are analysed. Altogether 17.3 per 1 000 of the children born during this period were born in multiple births. The perinatal mortality for the twin babies was 64 per 1 000 born, with the mortality higher in the less specialized hospitals than the others. Twin no. 1 suffered perinatal death in 67 cases per 1 000 and twin no. 2 in 60 cases per 1 000. For twins of primiparae the losses were 92 per 1 000 children and for twins born to multiparae 51 per 1 000. Altogether 72 per 1 000 male twins died perinatally compared to 52 per 1 000 female twins. The most heavy losses occurred among the low-weight premature twins and in these cases both twins often suffered perinatal death. 相似文献

Rat liver and kidney slices were incubated at 37 degrees C for 1 h in 1.0 ml of Krebs-HCO3 buffer containing 10mM glucose and one of the following: 5 mM [8-14C]ATP, 5 mM [8-14C]ADP, 5 mM [8-14C]AMP, or 5 mM [8-14C]ation medium and tissue extract were subjected to electrophoretic separation and the radioactivity present in ATP, ADP, AMP, IMP, inosine, adenosine, and hypoxanthine was counted. Extensive degradation of the added nucleotide was observed in the presence of both tissues. The concentrations of 14C-labeled ATP and ADP found in the liver and kidney indicated that these compounds were present within the cells. Evidence is presented which suggests that ATP, and to a lesser extent ADP, entered the liver and kidney as such and were not synthesized within the cell from 14C-labeled adenosine. 相似文献

In the silver female eel (Anguilla anguilla L.) maintained in fresh water, surgical removal of Stannius corpuscles (SC) resulted in: a) A significant increase of wet weight of gill cells and the dry weight of gill filaments expressed as function of body weight. b) A proliferation and a hypertrophy of chloride cells shown by a significant rise of cell volume expressed as a precentage of the epithelial volume. c) An increase of the calcium (Ca) binding protein activity in the total branchial mucosa. These modifications are not observed when eels are maintained in Ca-free water. The results are discussed in relation to the Ca fluxes across gills in eels deprived of SC and gill morphological changes during sea water adaptation. 相似文献

Advanced low-grade lymphomas are usually incurable with conventional-dose chemotherapy. It is uncertain whether cures are possible with high-dose therapy and bone marrow transplant from a human leukocyte antigen (HLA)-identical sibling. We sought to determine the outcome of HLA-identical sibling bone marrow transplants in advanced low-grade lymphoma in an observational study of 113 patients conducted at 50 centers participating in the International Bone Marrow Transplant Registry (IBMTR). The median patient age was 38 years (range, 15 to 61). Eighty percent had stage IV disease at the time of transplantation. The median number of prior chemotherapy regimens was two (range, 0 to 5). Thirty-eight percent had refractory disease and 29% a Karnofsky performance score (KPS) less than 80%. All patients underwent allogeneic bone marrow transplantation from a HLA-identical sibling donor. The conditioning regimen included total-body irradiation (TBI) in 82% of patients; cyclosporine was used for graft-versus-host disease prophylaxis in 74%. Survival, disease-free survival, recurrence rate, treatment-related mortality, and causes of death were determined. Three-year probabilities of recurrence, survival, and disease-free survival were 16% (95% confidence interval [CI], 9% to 27%), 49% (95% CI, 39% to 60%), and 49% (95% CI, 39% to 59%), respectively. Higher survival was associated with pretransplant KPS >/=90%, chemotherapy-sensitive disease, use of a TBI-containing conditioning regimen, and age less than 40 years. We conclude that high-dose therapy followed by transplantation from a HLA-identical sibling leads to prolonged survival in some patients with advanced low-grade lymphoma. Most mortality is treatment-related, and recurrences are rare. 相似文献

The safety profile, tolerability, pharmacodynamics, and pharmacokinetics of four doses of recombinant human granulocyte colony-stimulating factor (filgrastim) were assessed in healthy volunteers in a double-masked, placebo-controlled, parallel-group trial. Healthy subjects received subcutaneous injections of filgrastim 75 microg (n = 8), 150 microg (n = 4), 300 microg (n = 4), 600 microg (n = 8), or placebo (n = 6) daily for 10 consecutive days. Blood samples were drawn daily immediately before the injection and on days 1 and 10 serially throughout the day. Increased absolute neutrophil counts (ANCs) were seen within 90 minutes of drug administration in subjects in all dose groups, peaking approximately 12 hours after administration. This increase was dose related in subjects in the three lower dose groups. The time to peak ANC on day 10 was approximately 9 hours, with a daily ANC profile in all four dose groups that was similar to the profile on day 1. In all dose groups, ANCs were near baseline within 48 hours of discontinuation of filgrastim. Mild, reversible thrombocytopenia was reported in 4 of 10 subjects in the highest dose group. Two subjects in the filgrastim 600-microg group were withdrawn for adverse events. Filgrastim had a good safety profile and caused dose-related increases in ANC when administered to healthy volunteers for up to 10 days. 相似文献
