    Abstract In patients with the carcinoid syndrome flushing provoked by intravenous noradrenaline, adrenaline, and dopamine, and by oral alcohol, was accompanied by a rise in bradykinin concentration in arterial blood. Flushing provoked by the catecholamines was blocked by intravenous phentolamine which simultaneously inhibited the rise in bradykinin concentration. Intravenous phentolamine in high doses also blocked flushing provoked by alcohol. The time sequence of alcohol-induced flushing and the inhibition of this flushing by α-adrenergic blockade suggests that alcohol might release a catecholamine which acts upon the tumour cell to release kallikrein.

    Concentrations of corticosterone in brain areas of TO strain mice were measured by radioimmunoassay. The studies examined the effects of routine laboratory maneuvers, variation during the circadian peak, adrenalectomy, social defeat and acute injections of alcohol on these concentrations. Brief handling of mice increased corticosterone levels in plasma but not in striatum and reduced those in the hippocampus. Single injections of isotonic saline raised the plasma concentrations to a similar extent as the handling, but markedly elevated concentrations in the three brain regions. Five minutes exposure to a novel environment increased hippocampal and cerebral cortical corticosterone levels and striatal concentrations showed a larger rise. However, by 30 min in the novel environment, plasma concentrations rose further while those in striatum and cerebral cortex fell to control levels and hippocampal corticosterone remained elevated. Over the period of the circadian peak the hippocampal and striatal concentrations paralleled the plasma concentrations but cerebral cortical concentrations showed only small changes. Adrenalectomy reduced plasma corticosterone concentrations to below detectable levels after 48 h but corticosterone levels were only partially reduced in the hippocampus and striatum and remained unchanged in the cerebral cortex. Single or repeated social defeat increased both brain and plasma concentrations after 1 h. Acute injections of alcohol raised the regional brain levels in parallel with plasma concentrations. The results show that measurements of plasma concentrations do not necessarily reflect the levels in brain. The data also demonstrate that corticosterone levels can change differentially in specific brain regions. These results, and the residual hormone seen in the brain after adrenalectomy, are suggestive evidence for a local origin of central corticosterone.

    The effect of homeopathically potentiated ethanol (C30 and C200) on ethanol metabolism was studied in alcoholized rats. We measured ethanol concentration in the blood, alcohol dehydrogenase activity in the liver, and contents of biogenic monoamines in the hypothalamus, septum, and whole blood. Potentiated preparations of ethanol were efficient after long-term treatment and delayed ethanol elimination from the blood. Preparation C200 increased alcohol dehydrogenase activity. Potentiated preparations of ethanol (particularly C200) produced a positive effect on catecholaminergic and serotoninergic systems of the brain, i.e. they enhanced protective and adaptive reactions.

    As a preliminary step to evaluating the acute neurobehavioral effects of hydrocarbon solvents and to establish a working model for extrapolating animal test data to humans, joint neurobehavioral/toxicokinetic studies were conducted which involved administering ethanol to rats and volunteers. The specific objectives of the present studies were to evaluate the acute central nervous system (CNS) effects of ethanol in rats and humans and to assess relationships between internal levels of exposure and behavioral effects. A more general objective was to validate a battery of neurobehavioral tests that could be used to carry out comparative studies in both species. Accordingly, a range of tests including standardized observational measures, spontaneous motor activity assessments and learned visual discrimination performance was utilized in rat studies to evaluate acute CNS effects. Groups of rats were given ethanol at levels of approximately 0.5, 1.0 or 2.0g/kg, with blood level measurements to verify internal doses. In a volunteer study, 12 healthy male subjects were given 0.65g/kg ethanol, a level approximating the limit for motor vehicle operation in The Netherlands, and neurobehavioral effects were measured prior to and 1 and 3h after ethanol administration, with a computerized neurobehavioral test battery. Blood and air measurements were made to quantify internal doses. Results of the behavioral tests in rats provided evidence of ethanol-induced changes in neuromuscular, sensori-motor, and activity domains. There were also significant changes in visual discrimination, particularly in the areas of general measures of responding and psychomotor speed. In humans there were small but statistically significant effects on learning and memory, psychomotor skills and attention. However, the effects were subtle and not all parameters within given domains were affected. These studies demonstrated a qualitative similarity in response between rats and humans.

    Previous work demonstrated that the locomotor stimulant actions of amphetamine, cocaine and nicotine were increased when these drugs were given during the abstinence phase after chronic ethanol consumption. These changes were seen at 6 days and at 2 months after cessation of alcohol. The present study examined neuronal alterations which might be related to these changes in behaviour. Markedly reduced spontaneous firing rates of dopaminergic cells in the ventral tegmental area (VTA) in midbrain slices were seen 6 days into the abstinence period after cessation of chronic ethanol consumption, but by 2 months the firing rates had returned to control values. Increased affinity of striatal receptors for the D1-like receptor ligand 3H-SCH23390, but no change in the receptor density, was found both at the 6 day and the 2 month intervals. The binding properties of striatal D2-like receptors, of D1-like and D2-like receptors in the frontal cerebral cortex, and the release of tritiated dopamine from slices of striatum or frontal cerebral cortex, were unchanged at 6 days and 2 months. It is suggested that the decreased neuronal firing leads to a persistent increase in sensitivity of D1-like receptors and that these changes could explain the increased effects of the other drugs of abuse.

    Background: Essential tremor is one of the most common movement disorders in elderly people. The hypothesis of a disregulation ofN‐methyl‐d‐aspartate (NMDA) pathways has been suggested. It was shown experimentally that infusion of NMDA in cerebellar nuclei down‐regulates glutamate release.Methods: We assessed the effects of intranuclear administration of harmaline on the NMDA‐mediated regulation of glutamate in rats using reverse dialysis. We hypothesized that ethanol, which improves essential tremor in the clinic, antagonizes the effect of harmaline upon glutamatergic transmission. We tested the interaction of ethanol and harmaline upon glycerol (a marker of membrane turn‐over), lactate, and pyruvate concentrations.Results: Harmaline increased the concentrations of glutamate and impaired the NMDA‐mediated regulation of glutamate. Ethanol decreased the concentrations of glutamate during NMDA stimulation in case of pre‐administration with harmaline. Concentrations of glycerol rose with harmaline. Glycerol levels markedly decreased during NMDA infusion when inhibitors of nitric oxide synthase, α‐amino‐3‐hydroxy‐5‐methylisoxazole‐4‐propionate antagonists or NMDA antagonists were administered. Harmaline increased lactate/pyruvate ratios during NMDA infusion but these ratios returned to normal values in presence of ethanol.Discussion: We provide a possible mechanism for the beneficial effect of ethanol on essential tremor. The concept of glutamatergic disregulation underlying essential tremor is highlighted. Consequences for our understanding of essential tremor are discussed.

    Background Phase-contrast X-ray computed tomography imaging (PCI) based on crystal X-ray interferometry can detect minute density differences within biological soft tissues without contrast agents. Ethanol fixation yields increased tissue-background density differences due to the dehydrating and delipidifying effects of ethanol. Purpose To obtain high image contrast of cerebral white matter structures in PCI, tissue fixation using ethanol and routinely used formalin have been examined. Material and Methods Ethanol-fixed (EF) (n = 4) and formalin-fixed (FF) (n = 4) rat brains were imaged by crystal X-ray interferometry-based PCI. Tissue staining/microscopy was also performed for histological comparison and myelin density evaluation. Three-dimensional white matter tract images were reconstructed. Results Superior image contrast was obtained in the images of EF brains (EF images) compared to those of formalin-fixed brains (FF images), particularly for white matter structures. Significant density differences between the white matter structures and hippocampus ( P < 0.01)/thalamus ( P < 0.001) were observed in the EF, but not FF, images. Ethanol fixation enhanced the image contrast of white matter tracts by approximately sixfold compared to formalin fixation, and close agreement (r2 = 0.97; P < 0.05) between the density values on the CT images and the myelin density values in histological images was observed for the EF brains. Three-dimensional reconstruction of the white matter tracts was possible from the EF images, but not FF images. Conclusion Ethanol fixation resulted in marked contrast enhancement of cerebral white matter structures in PCI. Thus, high-resolution PCI using ethanol for tissue fixation could be valuable for experimental neurological studies and postmortem neuropathology evaluation.

    The spin-lattice (T1) and spin-spin (T2) relaxation times of liver in 42 normal volunteers (21 male and 21 female) were measured using a calibrated 0.08 T resistive imager capable of accurate and reproducible relaxometry. T1 was determined using an interleaved gradient echo saturation recovery and inversion recovery technique and T2 using a four-echo Carr-Purcell-Meiboom-Gill sequence. The ranges obtained were T1 = 213 +/- 14 ms and T2 = 66 +/- 5 ms. More specific ranges were obtained for each sex and for younger and older subjects. A small variation in T1 was found between older (greater than 40 years) and younger (less than 40 years) subjects, but no such effect was observed in the case of T2. No significant variations were found when female volunteers were imaged at weekly intervals through the menstrual cycle, when a male volunteer was imaged repeatedly over the course of several months or when male volunteers consumed small quantities of alcohol.

    Authors: M.J. Fardy; D.W. Patton;

    A retrospective study was carried out on 82 patients whose symptoms of trigeminal neuralgia were controlled by repeated peripheral alcohol nerve blocks in order to assess the associated complications. Peripheral alcohol nerve blocks were invariably associated with swelling and discomfort lasting several days. Significant complications occurred in 3 out of 413 nerve blocks administered over a 20-year period.
