The spinal antinociceptive interaction between the opiate receptor subtype agonists morphine (mu), U69593 (kappa) and [D-Pen2,5]-enkephalin (DPDPE; delta) with clonidine (alpha 2 adrenergic) was examined. Male SD rats received fixed ratios of clonidine to morphine (10:1), U69593 (1:3), or DPDPE (10:1) through catheters terminating at the lumbar cord. Graded(More)
Objective: The pharmacokinetics of orally and intravenously administered valsartan were determined in two studies. In a first pilot study, three i.v. doses of valsartan were given in an ascending manner (5, 10 and 20 mg) to evaluate tolerability and basic pharmacokinetics of the i.v. formulation. In a second study, the absolute bioavailability of 80 mg(More)
The antinociceptive interaction on the tail flick (TF) and hot plate (HP) tests between opioid analgesics and medetomidine after intravenous (iv) or intrathecal administration were examined by isobolographic analysis. Male Sprague-Dawley rats received fixed ratios of medetomidine to morphine, fentanyl, and meperidine of 1:10 and 1:30, 10:1, and 1:3,(More)
The antinociceptive interaction of opiate analgesics with clonidine was examined with the tail-flick and 55 degrees C hot plate tests. Male Sprague-Dawley rats received fixed ratios of clonidine to fentanyl, meperidine or morphine by i.v. and intrathecal injection. Data are expressed as percentage of maximal possible effect and the dose producing 50(More)
OBJECTIVE Valsartan is an oral antagonist of angiotensin II that competes with angiotensin II for the AT1-receptor and is being developed as an antihypertensive agent. This study assessed the ability of 80 mg valsartan to inhibit the pressor effect of exogenous angiotensin II in healthy normotensive men, first after a single dose and then after multiple(More)
Oxcarbazepine (OXC) is an antiepileptic drug. In humans, OXC is metabolized via reduction and conjugation. Monohydroxy derivative of OXC (MHD) is the major pharmacologically active component after OXC ingestion. This study was performed to characterize the disposition of the two enantiomers of MHD after oral and intravenous administration and to estimate(More)
BACKGROUND Allergen-specific T helper 2 (Th2) cells play an important role in the pathogenesis of atopic disorders. To date, no model system exists in humans that would allow the monitoring of a developing de novo Th2 immune response in vivo. OBJECTIVE The aim of the experiment was to establish an immunization protocol inducing a de novo Th2 response in(More)
A new computerized test for visual neglect and extinction was developed and evaluated by testing twenty-five patients with right-hemisphere cerebrovascular accidents. The test consisted of a series of unilateral or bilateral lights on a semicircular array to which the subject responded by pushing a button. A computer controlled the sequence of stimuli and(More)
1. Oxcarbazepine (OXC), the 10-keto analogue of carbamazepine (CBZ), has similar anticonvulsant efficacy and possibly improved patient tolerability. Unlike CBZ, it is metabolised by reduction and may not induce hepatic monooxygenase enzymes. 2. Serum concentrations of OXC and its active metabolite 10-OH-carbazepine (10-OH-CZ) were followed after a single(More)
