Lymphadenopathy-associated virus antibodies and T cells in hemophiliacs treated with cryoprecipitate or concentrate 总被引:1,自引:0,他引:1

Evidence for exposure to lymphadenopathy-associated virus (LAV) was investigated in 48 patients with hemophilia, 15 of whom had been treated exclusively with single-donor cryoprecipitate. The prevalence of antibodies to LAV in all patients was 53% in 1983 and 63% in 1984, while in patients treated only with cryoprecipitate, the prevalence was 31% in 1983 and 40% in 1984. Patients treated with any concentrate had a seroprevalence of 65% in 1983 and 77% in 1984. Seropositive patients were more likely to have a significant reduction in the ratio of helper to suppressor T cells, absolute numbers of helper T cells, and T cell function in vitro. Seven of 18 patients who were seronegative in 1983 had seroconverted by 1984. The relative risk of seroconversion for patients using any concentrate since 1981 compared with those using cryoprecipitate only was 3.9 (P = .04). Nevertheless, the rate of conversion in the latter group was 18% per year. 相似文献

Adenocarcinoma of the prostate and rectum are common male pelvic cancers and may present synchronously or metachronously and, due to their anatomic proximity. The treatment of rectal or prostate cancer (in particular surgery and/or radiotherapy) may alter the presentation, incidence and management should a metachronous tumour develop. This review focuses on the interaction between prostatic and rectal cancer diagnosis and management. We have restricted the scope of this large topic to general considerations, management of rectal cancer after prostate cancer treatment and vice versa, management of synchronous disease and cancer follow-up issues. 相似文献

Type 2 diabetes is a polygenic disease characterized by interaction of environmental and genetic factors. The paraoxonase 1 gene (PON1) 55 and 192 polymorphisms have been reported to be associated with type 2 diabetes and its complications. Our aim is to study the PON1 55, 192 gene polymorphisms and enzyme activity in type 2 diabetic Egyptian population with complications. 100 type 2 diabetic patients with complications (34 with cardiac and 66 with microvascular complications (neuropathy, retinopathy and/or nephropathy)). This was in addition to 100 healthy control subjects of matched age and sex were taken. PON1 55 L?M and 192 Q?R gene polymorphisms and PON1 enzyme activity serum levels were detected. The LL genotype of PON1 55 polymorphism and QR and QQ genotypes of PON1 192 polymorphism were more frequent among the patients with diabetic complications. The PON1 enzyme activity levels were lower among the diabetic patients than in control subjects. PON1 55 and 192 polymorphisms and enzyme activity seems to be related to diabetic complications in this population. 相似文献

Introduction Allergic diseases are unfortunately on the increase. This is due to the massive exposure to chemicals and pollutants contained in the air we breathe, in the food we eat and in the water we drink. This is also due both to the stressful life we lead nowadays, which causes energetical unbalances in our immune system, and to the contact with unfamiliar allergens coming from foreign Countries. 相似文献

This study investigated the effect of alcohol consumption and smoking during pregnancy on the fatty acid composition of the infants. A total of 40 very-low-birth-weight (VLBW) infants, weighing between 750 and 1500 g, were enrolled in the study after being hospitalized and ventilated for respiratory distress syndrome (RDS). Maternal and infant demographic information was recorded. Questions regarding maternal smoking (none, < 10 and > or = 10 cigarettes/d) and alcohol consumption (none, occasionally, moderate and severe) were recorded. Erythrocyte membrane (EMB; n = 40) total fatty acid analyses were performed at birth (baseline) and on days 14 and 28 postnatally. During pregnancy, 42% of mothers consumed alcohol and 50% smoked. At birth, infants of mothers who smoked and consumed alcohol during pregnancy, had significantly higher blood docosahexaenoic acid (DHA; p < 0.05) than infants of mothers who abstained from both alcohol and smoking. The consequences of this finding remain unknown. 相似文献

目的:研究金属硫蛋白(MT)对氧自由基损伤线粒体的保护作用以探讨其细胞保护机制。方法:采用FeSO4/抗坏血酸自由基发生系统直接损伤线粒体,测定Ca(2+)-Mg(2+)-ATPase活性和Ca(2+)摄入的变化。结果:MT能够直接拮抗氧自由基对线粒体Ca(2+)-Mg(2+)-ATPase活性和Ca(2+)摄入的抑制作用(P<0.01)。结论:MT对氧自由基损伤线粒体有明显保护作用,MT对细胞器线粒体的保护作用可能是细胞保护机制之一。 相似文献
