Chronic alcoholization by alcohol inhalation was used to studythe properties of magnesium, a non-competitive NMDA receptorantagonist, and CGP 39551, a competitive NMDA receptor antagonist,on behavioural dependence as estimated by the free-choice paradigm[alcohol 10% (v/v) vs. water], on the hypermotility after alcoholwithdrawal, and finally on the cortical vascularization. Thefirst experimental group received the drugs per os during thewhole alcoholization period. Magnesium (20 mg/kg/day) decreasedthe alcohol dependence while CGP 39551 (5 and 10 mg/kg/day)increased, in a dose-dependent manner, the dependence to alcohol.A second group of animals received the same drugs at the samedosages, not simultaneously during chronic alcoholization, butimmediately after alcoholization in one shot i.p. injection.In this case, rats receiving 5 mg/kg CGP 39551 never showedany dependence towards alcohol, while 10 mg/kg CGP 39551 or20 mg/kg magnesium prolonged the number of days of alcohol dependence.These results thus indicate the close interaction between NMDAreceptor function and dependence for alcohol. Magnesium hadno effects on hypermotility, while CGP 39551-treated animalspresented a decrease in the hypermotility observed after alcoholwithdrawal. Neither drug affected the hypervasculanzation accompanyingthe chronic alcoholization. 相似文献

To determine whether patients with a HLA-identical sibling donor have a better outcome than patients without a donor, an analysis on the basis of intention-to-treat principles was performed within the framework of the EORTC-GIMEMA randomized phase III AML 8A trial. Patients in complete remission (CR) received one intensive consolidation course. Patients with a histocompatible sibling donor were then allocated allogeneic bone marrow transplantation (alloBMT), the patients without a donor were randomized between autologous BMT (ABMT) and a second intensive consolidation (IC2). 831 patients <46 years old and alive >8 weeks from diagnosis were included. HLA typing was performed in 672 patients. AlloBMT was performed during CR1 in 180 (61%) out of 295 patients with a donor. Another 38 patients were allografted: five in resistant disease, 14 during relapse and 19 in CR2. ABMT was performed in 130 (34%) out of 377 patients without a donor in CR1, in six (2%) patients during relapse and in 38 (10%) patients during CR2. The disease-free survival (DFS) from CR for patients with a donor was significantly longer than for patients without a donor (46% v 33% at 6 years; P = 0.01, RR 0.78, 95% confidence interval 0.63–0.96). The overall survival from diagnosis for patients with a donor was longer, but not statistically significant, than for patients without a donor (48% v 40% at 6 years; logrank P = 0.24). When patients were stratified according to prognostic risk groups, the same trend in favour of patients with a donor was seen for survival duration and the DFS remained significantly longer for this group of patients. 相似文献

Non-invasive Analysis of Simulated Pacemaker Failure Available in Multiprogrammable Pulse Generators
Non-invasive analysis of muscle fascicuhtion using selected sensitivity settings is described This case report demonstrates trouble-shooting methods afforded by the multi-parameter programmable pulse generator while avoiding invasive generator and lead analysis Multiple pacing modes and sensitivities allow simulation of apparent generator malfunctioning as well as variable programming modes best suited to pacing needs 相似文献

With improved pacemaker lead design and materials, complications caused by lead problems have decreased.4,5 There have been isolated reports of leads severed by suture material but they have been rare. Presented is a case of suture-induced "pseudo-fracture" in a urethane-insulated ventricular lined endocardial lead (Medtronic Model #6971-58). No loss of capture or sensing function has been encountered eight months following initial implantation. It is felt that the softer, stronger urethane permitted compression and resulted in a radiographic suggestion of a fractured lead, but lead integrity does not seem to have compromised. Although (his may be an inconsequential radiographic finding, it could lead to an inappropriate lead removal unless it is properly interpreted. (PACE, Vol. 4, November-December, 1981) 相似文献
