Patients were randomly allocated to one of two groups; intravenous or epidural analgesia, with twenty patients in each group. General anesthesia was induced with thiopentone 5-6 mgkg-1 and maintained with 0.8-1.0% isoflurane and 66% nitrous oxide in 33% O2. The trachea was intubated after administration of vecuronium 0.1 mgkg-1. Patients in the epidural analgesia groups then received, by random...

Lichens are widely used to assess the atmospheric pollution by heavy metals and radionuclides. However, few studies are available in publications on using lichens to qualitatively assess the atmospheric pollution levels. The paper presents research results applying epiphytic lichens as bio-monitors of quantitative atmospheric contamination with uranium. The observations were conducted during 2....

Antagonism of the discriminative stimulus properties of 10 mglkg cocaine was studied in rats by use of the dopamine Dl antagonist SCH 23390 and the Dl antagonist haloperidol. Whereas SCH 23390 and haloperidol were by themselves unable to antagonize the cueing properties of cocaine, the combination of both dopamine antagonists resulted in a complete blockade of the cocaine cue. In the presence o...
