Non-O1 Vibrio cholerae was isolated from rivers, creeks, washes, irrigation canals, and ditches in western Colorado during the summer of 1985. The organism occurred in fresh water (less than or equal to 5 mmol of Na+ per liter) as well as in water of higher salinity (approximately equal to 17 mmol per liter). Sixteen serovars of non-O1 V. cholerae were Sixteen serovars of non-O1 V. cholerae were identified among the environmental isolates. All of the isolates were cytotoxic to Y-1 mouse adrenal cells. 相似文献

The rosette inhibition test was used in the clinical management of organ allografts to estimate the amount of immunosuppressive drugs necessary to prevent rejection. In patients surviving more than three months renal function appeared to be better than in a similar group of patients managed without the test. It is suggested that this was due to a reduction in the number of clinical or subclinical rejection episodes. On the other hand, the test indicates that in many cases the level of immunosuppression should be much higher, and if this advice is followed the patients become increasingly exposed to the risk of infection. In other words, those patients with good renal function remained well, whereas those who might otherwise have rejected their kidney and survived had in fact died of sepsis. 相似文献

Forty-six children with the nephrotic syndrome whose renal biopsy specimens showed minimal changes and whose response to corticosteroid therapy was unsatisfactory were treated with cyclophosphamide. Three patients were completely steroid-resistant from the outset and the remainder were steroid-dependent. In several patients steroids controlled the condition less effectively with time. Most patients showed signs of steroid toxicity, and growth retardation was striking.A moderate leucopenia was induced with cyclophosphamide, and treatment was maintained for three to four months in the majority of cases. Thirty-eight children (83%) have remained in complete remission off all treatment for periods of 3 to 23 months, 33 after one course of cyclophosphamide and five after a second course. Two other patients who remitted but relapsed later are still on treatment. In only six patients was full remission not obtained, and three of these were steroid-resistant from the start. Two died from pneumonia and adrenal failure and four continued to have proteinuria, though in one an impressive reduction occurred.The results indicate that cyclophosphamide therapy is an effective alternative for nephrotic children with normal glomeruli on light microscopy who develop steroid dependence or resistance, and who exhibit toxic effects of steroid therapy. 相似文献

Corticosteroids have the major role in the immunosuppressive treatment of patients who have received renal transplants. Despite their extensive use there is still debate about the appropriate dose that will prevent rejection of the renal allograft with the least morbidity. From March 1979 to November 1981 a randomised controlled trial of high (33 patients) v low oral dose (34 patients) of prednisolone along with azathioprine was conducted in recipients of first cadaveric transplants who had received a blood transfusion within six months of transplantation. The main difference in outcome between the two groups was a high incidence of some infections in the high dose group. Patient mortality, graft survival, transplant function, and number of rejection episodes were indistinguishable in the two groups, but rejection episodes tended to occur later in the high dose group. These findings suggest that the use of lower doses of corticosteroids soon after cadaveric renal transplantation does not jeopardise graft survival and results in lower patient morbidity. 相似文献

Many patients over the age of 55 with end stage renal disease in the United Kingdom are denied dialysis or transplantation. Although the reasons are complex, anticipation of a poor prognosis for these patients might explain why most British renal units impose an arbitrary age limit on the acceptance of patients for treatment. A study was therefore conducted to examine the prognosis and quality of life of 84 patients (mean age 59.6 years, range 55-72) accepted into our renal replacement programme from the beginning of 1975. The five year survival of the patients was 62.0% with 78.1% of the survivors either having successful transplants or caring for themselves using home haemodialysis or continuous ambulatory peritoneal dialysis. The results show that in terms of survival, economics, and rehabilitation it is both feasible and reasonable to treat middle aged and elderly patients with end stage renal disease. These patients should therefore not be denied dialysis or transplantation on the basis of age alone, and the lack of resources and other factors that allow this state to persist in Britain should be rapidly redressed. 相似文献

Many nuclear factors are concentrated within nonmembrane-bound subnuclear bodies. The Cajal body is an example of a conserved nuclear compartment that has been linked to molecular disease. Recent studies have shown Cajal bodies to be surprisingly mobile and offer clues about their function in the cell. 相似文献
