The pharmacokinetics of two benzodiazepine hypnotics, flunitrazepam and loprazolam, was determined on two occasions in two groups of eight healthy volunteers. Single 2-mg oral doses of either drug were given in the fasting state at morning on one occasion and after a standard dinner at night on another. Compared with administration of drugs in the fasting(More)
A deficit of nigrostriatal, mesocortical and mesolimbic dopamine systems in Parkinson's disease is well known. We know less about the involvement of tuberoinfundibular dopamine (TID) systems. In untreated (naive or wash-out) men with Parkinson's disease, we studied TID function through basal and stimulated plasma levels of growth hormone, prolactin and(More)
Laminin may alter the biological behavior of gliomas. Therefore, we investigated the expression of two laminin receptors, alpha6 beta1 and alpha6 beta4 integrins in normal brain, astrogliotic brain, and astrocytomas as compared to other central nervous system (CNS) tumors. In most CNS tumors, the expression of these integrins was unchanged in neoplastic as(More)
The imaging of cerebral gliomas with radiolabelled monoclonal antibodies (MoAbs) has been previously reported. However, previous studies have been hampered by the drawback of a low tumour to non-tumour ratio. In order to overcome this problem we have developed a three-step pre-targeting method using the avidin-biotin system. The rationale of this technique(More)
In randomly selected chronic alcoholics hospitalised for the first time for detoxification a high prevalence (68%) of cognitive deficits was found. Peripheral neuronal damage was seen in 74%, autonomic neuronal damage in 24%. Cognitive deficits were not correlated with age, daily ethanol intake, duration of alcohol abuse or severity of liver damage. There(More)
In order to evaluate the usefulness of transcranial Doppler (TCD) in carotid artery surgery, 90 patients who underwent carotid endarterectomy were studied. Transcranial Doppler was performed preoperatively with digital compression of the carotid artery and intraoperatively at the time of cross-clamping, together with routine EEG monitoring. The percentage(More)
Six healthy, fasting volunteers were given single doses of chlordesmethyldiazepam by 1 mg i. v., or as drops or tablets. Chlordesmethyldiazepam and its metabolite, lorazepam, in multiple plasma samples and in urine collected for 120 h after each dose were determined by electron-capture GLC. Mean kinetic variables for intravenous chlordesmethyldiazepam were:(More)
The kinetics of a single 1-mg oral dose of chlordemethyldiazepam (CDDZ, En) was determined on two occasions in 8 healthy volunteers. CDDZ was given in the fasting state on one occasion and following a standard meal on another. Compared with the fasting state, administration of CDDZ with food prolonged the time to reach peak concentration (1.5 vs. 6.8 h(More)
of 3.5-5 months. Historically, radiotherapy alone has been the standard treatment for PCNSL; however, radiotherapy is rarely a curative treatment in PCNSL patients since response is usually short-lived, with a median survival of 12-14 months. 12,13 Moreover, the positive impact of chemotherapy progressively limited the indications for radiotherapy alone.(More)
