Mackus M, Stock AK, Garssen J, Scholey A, Verster JC. Alcohol hangover versus dehydration revisited: The effect of drinking water to prevent or alleviate the alcohol hangover. Alcohol 2024; 121:9-18. [PMID: 39069212 DOI: 10.1016/j.alcohol.2024.07.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2024] [Revised: 07/20/2024] [Accepted: 07/23/2024] [Indexed: 07/30/2024]
Abstract
The alcohol hangover is a combination of negative mental and physical symptoms which can be experienced after a single episode of alcohol consumption, starting when blood alcohol concentration (BAC) approaches zero. A popular theory suggests that dehydration is the primary cause of alcohol hangover and that the consumption of water could alleviate hangover symptoms. Here, the current evidence on the relationship between hangover severity, thirst, and water consumption is summarized. The positive correlations of the amount of water consumed with both hangover severity and thirst suggest that both dehydration and the hangover are co-occurring after-effects of alcohol consumption. While hangovers were typically relatively enduring, dehydration effects were usually mild and short-lasting. Survey data revealed that water consumption during or directly after alcohol consumption had only a modest effect in preventing next-day hangover. Also, the amount of water consumed during hangover was not related to changes of hangover severity and thirst. Thus, water consumption was not effective to alleviate the alcohol hangover. Taken together, these data suggests that alcohol hangover and dehydration are two co-occurring but independent consequences of alcohol consumption.

Neurosci Biobehav Rev 2023; 154:105427. [PMID: 37858908 PMCID: PMC10865927 DOI: 10.1016/j.neubiorev.2023.105427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 09/24/2023] [Accepted: 10/13/2023] [Indexed: 10/21/2023]
Abstract
Preclinical and human studies suggest a role of aldosterone and mineralocorticoid receptor (MR) in addiction. This scoping review aimed to summarize (1) the relationship between alcohol and other substance use disorders (ASUDs) and dysfunctions of the aldosterone and MR, and (2) how pharmacological manipulations of MR may affect ASUD-related outcomes. Our search in four databases (MEDLINE, Embase, Web of Science, and Cochrane Library) indicated that most studies focused on the relationship between aldosterone, MR, and alcohol (n = 30), with the rest focused on opioids (n = 5), nicotine (n = 9), and other addictive substances (n = 9). Despite some inconsistencies, the overall results suggest peripheral and central dysregulations of aldosterone and MR in several species and that these dysregulations depended on the pattern of drug exposure and genetic factors. We conclude that MR antagonism may be a promising target in ASUD, yet future studies are warranted.

Antioxidants (Basel) 2023; 12:1813. [PMID: 37891892 PMCID: PMC10604002 DOI: 10.3390/antiox12101813] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 09/23/2023] [Accepted: 09/28/2023] [Indexed: 10/29/2023] Open
Abstract
Consumption of high amounts of ethanol is a risk factor for development of cardiovascular diseases such as arterial hypertension. The hypertensive state induced by ethanol is a complex multi-factorial event, and oxidative stress is a pathophysiological hallmark of vascular dysfunction associated with ethanol consumption. Increasing levels of reactive oxygen species (ROS) in the vasculature trigger important processes underlying vascular injury, including accumulation of intracellular Ca2+ ions, reduced bioavailability of nitric oxide (NO), activation of mitogen-activated protein kinases (MAPKs), endothelial dysfunction, and loss of the anticontractile effect of perivascular adipose tissue (PVAT). The enzyme nicotinamide adenine dinucleotide phosphate (NADPH) oxidase plays a central role in vascular ROS generation in response to ethanol. Activation of the renin-angiotensin-aldosterone system (RAAS) is an upstream mechanism which contributes to NADPH oxidase stimulation, overproduction of ROS, and vascular dysfunction. This review discusses the mechanisms of vascular dysfunction induced by ethanol, detailing the contribution of ROS to these processes. Data examining the association between neuroendocrine changes and vascular oxidative stress induced by ethanol are also reviewed and discussed. These issues are of paramount interest to public health as ethanol contributes to blood pressure elevation in the general population, and it is linked to cardiovascular conditions and diseases.

Abstract
Hangovers are uncomfortable physiological symptoms after alcohol consumption caused by acetaldehyde, a toxic substance in which alcohol is metabolized by alcohol dehydrogenase (ADH). Rapid alcohol and acetaldehyde decomposition are essential to alleviate alcohol handling symptoms. This study investigated the effects of HY_IPA combined with Mesembryanthemum crystallinum, Pueraria lobata flower, and Artemisia indica on alleviating hangovers. A randomized, double-blind, parallel-group, placebo-controlled clinical study was conducted on 80 individuals with hangover symptoms. Alcohol intake was 0.9 g/bw with 40% whiskey, adjusted proportionately to body weight. The Acute Hangover Scale total score was 5.24 ± 5.78 and 18.54 ± 18.50 in the HY_ IPA and placebo groups, respectively (p < 0.0001). All nine indicators of the hangover symptom questionnaire were significantly improved in the HY_IPA group (p < 0.01). Blood alcohol and acetaldehyde concentrations rapidly decreased from 30 min in the HY_IPA group (p < 0.05). ADH and acetaldehyde dehydrogenase (ALDH) activities in the blood of the HY_IPA group were significantly higher than those in the placebo group at 0, 1, and 2 h after alcohol consumption (p < 0.01). The rapid hangover relief was due to increased ADH and ALDH. Therefore, HY_IPA effectively relieves hangover symptoms by decomposing alcohol and acetaldehyde when consumed before alcohol consumption.

Abstract
BACKGROUND Binge drinking is a common atrial fibrillation (AF) trigger, however the mechanisms are poorly understood. OBJECTIVE To investigate the effects of alcohol intoxication and hangover with rhythm monitoring and cardiac MRI. METHODS Patients underwent serial cardiac MRI pre- and post-binge with continuous Holter monitoring. Time periods analyzed: baseline (24 h pre-binge), consumption, hangover (0- 24 h post-consumption) and post-hangover (24-48 h post-consumption). RESULTS 50 patients (age 49 ± 15 years, 40% paroxysmal AF) completed the study (intake 8.4 ± 3.1 standard drinks). Mean heart rate increased from 72 ± 10 to 80 ± 13 beats per minute (bpm) during consumption (p < 0.001). The hangover period was characterised by higher daily atrial ectopic count (50, IQR 10-132 vs baseline 43, IQR 10-113; p = 0.04) and reduced heart rate variability (SDNN 55 ms, IQR 40-65 versus 62 ms, IQR 51-66; p = 0.007). There was evidence of heightened parasympathetic activity post-hangover with heart rate slowing (mean HR 54 ± 6 bpm; p = 0.03) and increased activity in the High frequency band when separating the complex heart rate variability waveform into its component rhythms (291 ms2, 97-538 versus baseline 237 ms2, IQR 104-332; p = 0.04). Three patients developed AF 11, 29 and 34 h post-binge. Cardiac MRI (2.7 ± 0.7 days post-binge) demonstrated a decrease in left atrial (LA) emptying fraction (57.9 ± 8.5 to 53.5 ± 6.7%; p = 0.003) but no change in LA volume, left ventricular ejection fraction or markers of ventricular inflammation. CONCLUSION Binge drinking is associated with sympathetic activation followed by a 'rebound' parasympathetic response and atrial mechanical dysfunction which may explain the propensity and temporal association between binge drinking and AF.

Abstract
Studies have demonstrated significant sex differences in alcohol intoxication effects. In contrast, the majority of studies on the alcohol hangover phase did not investigate sex differences. Therefore, the current study examined possible sex differences in the presence and severity of alcohol hangover symptoms. Data from n = 2446 Dutch students (male = 50.7%, female = 49.3%) were analyzed. They reported the presence and severity of 22 hangover symptoms experienced after their past month heaviest drinking occasion. Subjects were categorized according to their estimated peak blood alcohol concentration (eBAC) and presence and severity of the hangover symptoms were compared between men and women. In the lowest eBAC group (0% ≤ eBAC < 0.08%), no significant sex differences were found. In the subsequent eBAC group (0.08% ≤ eBAC < 0.11%), severity of nausea was significantly higher in women than in men. In the third eBAC group (0.11% ≤ eBAC < 0.2%), women reported higher severity scores on nausea, tiredness, weakness, and dizziness than men. Men reported the presence of confusion significantly more often than women, and women reported the presence of shivering significantly more often than men. In the fourth eBAC group (0.2% ≤ eBAC < 0.3%), women reported higher severity scores on nausea and tiredness than men. In the highest eBAC group (0.3% ≤ eBAC < 0.4%), no significant sex differences were found. In conclusion, across the eBAC groups, severity scores of nausea and tiredness were higher in women than in men. However, albeit statistically significant, the observed sex differences in presence and severity of hangover symptoms were of small magnitude, and therefore, have little clinical relevance.

Abstract
BACKGROUND Alcohol consumption is influenced by heritable factors. The genetic influence on usual high-density drinking, including alcohol intoxication and hangover, is unknown. We aim to estimate the heritability of usual high-density drinking. METHODS A total of 13,511 male twins in this cross-sectional study were included from the National Academy of Sciences-National Research Council (NAS-NRC) Twin Registry. Data on the frequency of alcohol intoxication and alcohol hangover over the past year, that is, usual high-density drinking (phenotypes), were collected through a self-administered questionnaire when twins were middle-aged in 1972. Structural equation modeling was used to estimate the variance components of phenotypes. RESULTS The mean of the frequency of usual high-density drinking in the entire twin population was 0.16 times per month for intoxication and 0.18 times per month for hangover. The heritability of usual alcohol intoxication was 50.7% (95% confidence interval [CI] 46.2 to 55.0) before and 49.9% (95% CI 45.3 to 54.2) after the body mass index (BMI) adjustment. The heritability of usual hangover was 55.4% (95% CI 51.2 to 58.6) before and 54.8% (95% CI 50.6 to 58.8) after adjustment for BMI. Unshared environmental factors between co-twins explained the remaining variance in alcohol intoxication and in hangover. CONCLUSIONS Both genetic and unshared environmental factors have important influences on usual alcohol intoxication and hangover. These findings are important in understanding the occurrence of and developing interventions for usual high-density drinking.

Abstract
In the present study, we investigated the role of angiotensin type I (AT1) receptor in reactive oxygen species (ROS) generation and mitogen-activated protein kinases (MAPK) activation induced by acute ethanol intake in resistance arteries. We also evaluated the effect of ethanol on platelet-derived growth factor receptors (PDGF-R) phosphorylation and the role of this receptor on ROS generation by ethanol. Ethanol (1 g/kg; p.o. gavage) effects were assessed within 30 min in male Wistar rats. Acute ethanol intake did not alter angiotensin I or angiotensin II levels in the rat mesenteric arterial bed (MAB). Ethanol induced vascular oxidative stress, and this response was not prevented by losartan (10 mg/kg; p.o. gavage), a selective AT1 receptor antagonist. MAB from ethanol-treated rats displayed increased SAPK/JNK and PDGF-R phosphorylation, responses that were not prevented by losartan. The phosphorylation levels of protein kinase B (Akt) and eNOS were not affected by acute ethanol intake. MAB nitrate levels and the reactivity of this tissue to acetylcholine, phenylephrine, and sodium nitroprusside were not affected by ethanol intake. Ethanol did not alter plasma antioxidant capacity, the levels of reduced glutathione, or the activities of superoxide dismutase and catalase in the rat MAB. Short-term effects of ethanol (50 mmol/l) were evaluated in vascular smooth muscle cells (VSMC) isolated from rat MAB. Ethanol increased ROS generation, and this response was not affected by AG1296, a PDGF-R inhibitor, or losartan. Finally, ethanol did not alter MAPK or PDGF-R phosphorylation in cultured VSMC. Our study provides novel evidence that acute ethanol intake induces ROS generation, PDGF-R phosphorylation, and MAPK activation through AT(1)-independent mechanisms in resistance arteries in vivo. MAPK and PDGF-R play a role in vascular signaling and cardiovascular diseases and may contribute to the vascular pathobiology of ethanol.

Abstract
Among the first screened 2439 males born in 1926 and 1927, aged 48-49 years at the time of screening and representing 76% of these age cohorts, uncontrolled or partly controlled hypertension was found in 7.5%. Of these individuals, 30% preferred to remain with their physicians, regardless of the degree of control they had achieved. Among those who were referred to the Hypertension Unit (5.2% of the screened population), elevated S-GT levels (greater than or equal to 1.10 mukat/l) were found in 38.3%, against 18.5% in the two cohorts. During 24 months of treatment and follow-up only two men among the entire group of hypertensives referred dropped out, both were heavy drinkers (greater than 80 g alcohol daily). The mean BP after treatment was significantly lower among men with normal than high S-GT values or in those who admitted to heavy drinking. Of the 99 males treated for more than two years, 82 (83%) were responders (supine DBP less than or equal to 95 mmHg). Of the non-responders, 70% were either heavy drinkers or had abnormal S-GT values. The possible role of alcohol in the pathogenesis of essential hypertension in middle-aged males is discussed.

Abstract
The Losartan Intervention For End point reduction in hypertension (LIFE) study showed superiority of losartan over atenolol for reduction of composite risk of cardiovascular death, stroke, and myocardial infarction in hypertensives with left ventricular hypertrophy. We compared hazard ratios (HR) in 4287 and 685 participants who reported intakes of 1-7 and >8 drinks/week at baseline, respectively, with those in 4216 abstainers, adjusting for gender, age, smoking, exercise, and race. Within categories, clinical baseline characteristics, numbers randomized to losartan and atenolol, and blood pressure (BP) lowering were similar on the drug regimens. Overall BP control (<140/90 mmHg) at end of follow-up was similar in the categories. Composite end point rate was lower with 1-7 (24/1000 years; HR 0.87, P<0.05) and >8 drinks/week (26/1000 years; HR 0.80, NS) than in abstainers (27/1000 years). Myocardial infarction risk was reduced in both drinking categories (HR 0.76, P<0.05 and HR 0.29, P<0.001, respectively), while stroke risk tended to increase with >8 drinks/week (HR 1.21, NS). Composite risk was significantly reduced with losartan compared to atenolol only in abstainers (HR 0.81 95% confidence interval, CI (0.68, 0.96), P<0.05), while benefits for stroke risk reduction were similar among participants consuming 1-7 drinks/week (HR 0.73, P<0.05) and abstainers (HR 0.72, P<0.01). Despite different treatment benefits, alcohol-treatment interactions were nonsignificant. In conclusion, moderate alcohol consumption does not change the marked stroke risk reduction with losartan compared to atenolol in high-risk hypertensives. Alcohol reduces the risk of myocardial infarction, while the risk of stroke tends to increase with high intake.

Abstract
It is known that exercise induces modification in blood haemostasis. It is, however, not known whether alcohol consumption post-exercise influences these modifications during recovery. Eleven moderately active young men were studied immediately after a standardised cycle ergometer test and during the 24-hour period of recovery. Alcohol (0. 7 g/kg body mass) was given 1 hour after exercise on one test occasion, while an equal volume of alcohol-free solution was administered on the other. Exercise induced a significant increase in factor VIII activity with a significant shortening of activated partial thromboplastin time. Parallel increases in tissue plasminogen activity and antigen with a concomitant decrease in tissue plasminogen activator inhibitor-1 activity were also observed after exercise. During recovery, while the increase in factor VIII activity post-exercise persisted in both trials, fibrinolytic activity demonstrated a sharp fall. The elevated factor VIII activity was significantly higher at 5 and 22 hours during the alcohol trial compared with the control. Although no demonstrable effect of alcohol on tissue plasminogen activator activity was present from 1 hour after ingestion onward, tissue plasminogen activator antigen and tissue plasminogen activator inhibitor-1 antigen increased significantly 22 hours following alcohol ingestion. Further comparison between trials revealed a higher plasminogen activator inhibitor-1 activity 5 hours after alcohol ingestion. In conclusion, exercise-induced changes to blood haemostasis are balanced during exercise but not during recovery. Alcohol consumption after physical exercise further perturbs blood haemostasis and could constitute a thrombotic risk.

Abstract
Alcohol consumption at rest is associated with disturbed water and salt regulation reflected by changed responses in the hydromineral hormones. This study investigated the effect of alcohol on endocrine systems involved in body fluid and electrolyte regulation under conditions of physical exercise in the heat, a situation in which under normal circumstances, the hydromineral hormones are stimulated in an attempt to preserve physiological homeostasis. Eight healthy male volunteers participated in two trials, which differed only in the presence or absence of alcohol (1.2 g alcohol.kg-1 body mass) in a cocktail drink. After consuming the cocktail, the subjects exercised for 60 min on a cycle ergometer (45% maximal oxygen consumption) at 35 degrees C. Compared to the control situation alcohol consumption (maximal plasma concentrations reaching about 1.08 g.l-1) produced an increase in body fluid loss (P < 0.05), but did not induce significant differences in plasma volume changes. Plasma volume decreased in both sessions during exercise (P < 0.01) and a significant rebound (P < 0.001) occurred during recovery. Osmolality was significantly higher (P < 0.001) during rest, exercise and recovery periods compared to the placebo trials, but no effect of alcohol on plasma Na+ and K+ concentrations was observed. In the alcohol test conditions, the arginine vasopressin (AVP) response to exercise was significantly dampened (P < 0.05). In contrast, alcohol had no effect on aldosterone or atrial natriuretic peptide (ANP). These results demonstrated that alcohol ingestion augmented body fluid losses due to a suppressive effect on AVP during physical exercise conducted in a warm environment. The increase in osmolality due to alcohol did not influence the aldosterone and ANP responses, which would suggest that total osmolality does not play a major role in the regulation of these hormones.

Abstract
Controversial results of fluid and electrolyte derangements in patients with moderate alcohol intoxication have been described. However, no information is available about severe alcohol intoxication. We investigated differences of hormonal disorders between alcohol-habituated and alcohol-naive subjects with severe ethanol intoxication. The hormonal derangements and recommendations on therapy of these patients are discussed. Thirty-three patients [10 alcohol-naive (group A) and 23 alcohol-habituated (group B) subjects] with severe alcohol intoxication (blood ethanol > 200 mg/dl) were selected for the study. Electrolytes and osmolarity of serum and urine, blood ethanol, vasopressin, renin, and aldosterone were determined on admission 2, 4, and 6 hr later. Fluid balance was calculated for each hour. All patients received isotonic saline solution according to urine production. Group A: On admission, serum osmolarity was increased (308 mOsmol/kg). Concomitantly, vasopressin level was elevated on admission (9.12 pg/ml). Increased serum osmolarity was correlated with elevated vasopressin levels (r = 0.8211; p < 0.005). Serum electrolytes, renin, and aldosterone values were within normal ranges. Group B: On admission, vasopressin level was significantly decreased (0.9 pg/ml), despite an elevated serum osmolarity (309 mOsmol/kg). Serum osmolarity remained high despite a sufficient fluid substitution. In addition, vasopressin level remained suppressed over the observation period. Aldosterone level was significantly increased on admission (319 ng/ml). Accordingly, serum sodium was increased from 142 to 148 mM/liter, and serum potassium was decreased from 3.9 to 3.4 mM/liter. Response to hyperosmolarity due to severe alcohol intoxication is different in alcohol-naive and alcohol-habituated subjects.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
This review summarizes emerging evidence that supports the notion of a separate brain renin-angiotensin system (RAS) complete with the necessary precursors and enzymes for the formation and degradation of biologically active forms of angiotensins, and several binding subtypes that may mediate their diverse functions. Of these subtypes the most is known about the AT1 site which preferentially binds angiotensin II (AII) and angiotensin III (AIII). The AT1 site appears to mediate the classic angiotensin responses concerned with body water balance and the maintenance of blood pressure. Less is known about the AT2 site which also binds AII and AIII and may play a role in vascular growth. Recently, an AT3 site was discovered in cultured neoblastoma cells, and an AT4 site which preferentially binds AII(3-8), a fragment of AII now referred to as angiotensin IV (AIV). The AT4 site has been implicated in memory acquisition and retrieval, and the regulation of blood flow. In addition to the more well-studied functions of the brain RAS, we review additional less well investigated responses including regulation of cellular function, the modulation of sensory and motor systems, long term potentiation, and stress related mechanisms. Although the receptor subtypes responsible for mediating these physiologies and behaviors have not been definitively identified research efforts are ongoing. We also suggest potential contributions by the RAS to clinically relevant syndromes such as dysfunctions in the regulation of blood flow and ischemia, changes in cognitive affect and memory in clinical depressed and Alzheimer's patients, and angiotensin's contribution to alcohol consumption.

Abstract
Stimulation of the peripheral renin-angiotensin system has been shown previously to decrease the voluntary intake of ethanol in the rat. The existence of a separate brain renin-angiotensin system, independent from that of the periphery, has been widely demonstrated. The brain renin-angiotensin system plays an important role in the regulation of water and electrolyte balance and neuroendocrine function. However, the role played by this system in the regulation of voluntary alcohol consumption has not yet been studied. The goal of the present work was to assess the feasibility of decreasing the voluntary alcohol intake in a strain of rats (Rapp SS/Jr rats) that have a genetic deficiency responsible for a low activity of the renin-angiotensin system and elevated alcohol intake. Adult Rapp SS/Jr rats received intraventricular transplants of fetal hypothalamic grafts (from normal donors), known to contain angiotensin-immunoreactive cell bodies. Our studies revealed that angiotensin-immunoreactivity in the cell bodies and fibres in the paraventricular, supraoptic and suprachiasmatic nuclei of the hypothalamus in Rapp SS/Jr rats was markedly reduced. Animals that had surviving grafts containing angiotensin-immunoreactive cell bodies in the dorsal third ventricle--but not in the ventral third ventricle, in the lateral ventricles, or sham operated animals--had a 40% decrease of their voluntary alcohol intake, when compared to their intake before surgery, or to the control group. However, water consumption was not reduced in both the sham and transplanted animals.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Using an animal model, we have investigated the effects of chronic ethanol ingestion on the regulation of atrial natriuretic peptide (ANP) synthesis and release. Male Sprague-Dawley rats were maintained for 6 weeks on a liquid diet of ethanol (up to 20% v/v) as part of a 2% solution of calf milk replacer. Weight-matched controls received an equal volume of ethanol-free solution, and normal animals drank ad libitum. All animals received rat chow throughout the experiment. This model produced physiologically relevant levels of blood ethanol, as concentrations at the time of sacrifice were 171.98 +/- 39.26 mg/dl. Plasma renin activity was significantly elevated in response to ethanol treatment, whereas circulating aldosterone concentration was reduced. No alterations in the plasma or atrial tissue levels of ANP were evident, although we did observe a significant increase in the ventricular tissue levels of ANP from 45.1 to 71.8 ng/g as a consequence of ethanol treatment. Levels of both atrial and ventricular ANP mRNA were not different between alcohol-treated and liquid-restricted control animals, although both groups showed significant increases in the amount of transcript in comparison with rats drinking ad libitum. No significant increases in either arterial blood pressure or heart/body weight ratio were observed for ethanol-treated rats. These results suggest that modifications in the renin-aldosterone axis can occur independently of alterations in the regulation of ANP under the influence of chronic ethanol ingestion.

Abstract
Since ethanol ingestion is associated with a disruption of water and electrolyte balance in a variety of species, we sought to evaluate the regulatory control of atrial natriuretic peptide (ANP) in response to acute doses of ethanol. Male Sprague-Dawley rats were administered a 5-g/kg dose of ethanol (40% w/v) via a gastric tube, while control animals received an equivalent volume of water. Expressed as a percentage of control, plasma ANP levels were 39.0%, 28.5%, and 23.6% in the ethanol-treated animals at 30, 60, and 120 min postintubation, respectively. Ethanol-treated animals displayed blood alcohol concentrations of 89.0, 137.6, and 214.1 mg/dl at the same time periods. After 120 min, plasma renin activity was elevated from 8.7 to 20.3 ng/ml/h in conjunction with an increase in the levels of circulating aldosterone from 16.3 to 42.5 ng/dl and an increase in plasma vasopressin from 2.2 to 3.6 pg/ml. Levels of atrial ANP mRNA remained consistent over the time course of the experiment, and no changes in the amount of ventricular ANP transcript were observed. Tissue ANP levels were similar between ethanol-treated and water-loaded control animals. In vitro experiments using cultured cardiac myocytes suggest that ethanol exposure may not directly affect ANP secretion. We propose that acute ethanol treatment may inhibit atrial distension and subsequently modify the control of ANP release under volume loading conditions.

Abstract
The renin-angiotensin system has traditionally been associated with the regulation of fluid and electrolyte balance. In this review we summarize the data which ascribes a completely new function to this system, i.e., the regulation of alcohol consumption. In addition, we suggest a possible mechanism for this effect based on the concept of a satiety or stop process. The approach taken was to examine the effect on alcohol intake of a wide variety of drug, genetic, dietary, surgical and neurosurgical manipulations, each of which has a range of biological effects characteristic of that manipulation, but all of which share the common property of altering activity in the renin-angiotensin system. The effect of these manipulations on alcohol intake was most parsimoniously explained by reference to their ability to raise or lower activity in the renin-angiotensin system. Any intervention which modulates activity in this system, either directly or indirectly, is likely to have consequences for alcohol consumption.

Abstract
The purpose of this study was to investigate the renal handling of sodium and potassium in rats during an acute ethanol (ETOH) administration and to relate any observed changes to alterations in renin-aldosterone secretion. Eight male Wistar rats, 7 to 8 weeks of age, were injected intraperitoneally (IP) with 1.0 g/kg body wt. ETOH (15% v/v, 95% ETOH in saline, pH 6.98, osmolality 284 mOsm/kg). Blood ETOH levels were 159 +/- 16 (Mean +/- SEM) and 120 +/- 12 mg/dl, 10 and 30 min after the ETOH injection respectively (p less than 0.05). Control animals were given either an equal volume (1.77 ml/100 g body wt.) of 0.9% saline (n = 6) or 5% dextrose solution (n = 4) with similar pH and osmolality. Following ETOH administration blood pH, urine pH, plasma bicarbonate (HCO3) concentration declined significantly (p less than 0.01) while glomerular filtration rate (GFR) and hematocrit (Hct) remained unchanged (p = 0.1). Mean fractional sodium excretion (FENa), fractional potassium excretion (FEK), and osmolar clearance (Cosm) fell significantly despite an increase in plasma sodium (p less than 0.01), potassium (p less than 0.05) and osmolality concentrations (p less than 0.05). There was no significant change in plasma aldosterone concentration (PA) or plasma renin activity (PRA) following the ETOH administration. No difference in GFR, FENa, FEK, Cosm, blood pH, urine pH, plasma electrolytes, PA, or PRA was observed following the saline or dextrose injections. In conclusion, acute ETOH administration in rats alters renal sodium and potassium excretion independent of changes in GFR, PA, PRA or plasma volume as reflected by Hct.

Abstract
This review examines some particular approaches that have been used to investigate factors that facilitate or constrain the self-administration of ethanol by rats. A technique for increasing ethanol self-administration in rats, the prandial drinking method, was examined and the effect of body-weight reduction on drug intake was discussed. Emphasis was placed on how ethanol intake may be controlled by processes in addition to the direct pharmacological actions of the drug in the CNS. These processes may be physiological. Evidence was presented for a relationship between activity in the renin-angiotensin system and the self-administration of ethanol. These processes may also be environmental. Using the place-conditioning technique, demonstrations were presented of how the context or situation in which ethanol is experienced may determine whether preference or aversion for the drug develops. Such a diversity in the factors that can potentially control ethanol intake may complicate the identification of the causes of alcohol abuse, but this same diversity also holds out greater hope that manipulations may be found to reduce excessive drinking in humans.

Abstract
Voluntary alcohol intake was examined in two models of renovascular hypertension known to differ in their effects on the renin-angiotensin system. In experiment 1, Two-Kidney, One-Clip (renin-dependent) hypertensive rats (T-K,O-C) or their sham operated controls were offered limited access to alcohol for 1 hr each day. Over a four week period the T-K,O-C rats drank significantly less 3% and 6% (w/v) alcohol solution than the sham operated controls. In experiment 2, One-Kidney, One-Clip (renin-independent) hypertensive rats or their sham operated controls were offered alcohol on a similar limited access basis. Over a four week period, the O-K,O-C rats did not show a reduction in the intake of either a 3% or 6% alcohol solution compared to the sham operated controls. These results provide further documentation for the role of the renin-angiotensin system in modulating alcohol intake. The process by which this system might influence alcohol intake is outlined.

Abstract
The voluntary intake of alcohol has been shown to be attenuated by a variety of manipulations which increase activity in the renin-angiotensin system. In the present study we examined the effects of peripheral injections of the peptide angiotensin II on alcohol drinking. The peptide produced a dose-dependent decrease in alcohol intake with 20 micrograms/kg having little effect, 200 micrograms/kg reducing intake by approximately 50% and 1 mg/kg virtually abolishing all alcohol drinking. This decrease was not due to a peptide induced motor deficit, or state of sickness, and could also not be accounted for by the increased water intake, or by a change in pharmacokinetics and taste function. These data provide direct evidence that angiotensin II can modulate voluntary alcohol drinking. The possibility that the level of angiotensin II serves as a satiety signal in alcohol drinking is discussed.

Abstract
Evidence is presented which supports the hypothesis that the renin-angiotensin (r-a) system regulates alcohol intake. Documented findings suggest that an elevated level of r-a activity represents a satiety signal which stops alcohol intake. The fact that alcohol itself is known to stimulate r-a activity suggests that its intake may in some sense be self-regulating and that levels of r-a activity below those which signal satiety may even be rewarding. The role of the r-a system in hypertension is also considered. The ability of alcohol to elevate r-a activity may be seen as a contributing factor to alcohol-induced hypertension because angiotensin is a potent pressor agent. Furthermore, the notion that lower levels of angiotensin may be rewarding permits the hypothesis that essential hypertension may, in part, be the result of a self-induced increase in endogenous angiotensin. This would explain the otherwise puzzling utility of the angiotensin converting enzyme inhibitors in the treatment of essential hypertension.

Abstract
Chronic alcohol consumption frequently leads to hypertension in humans. While previous reports have implicated the renin-angiotensin system as a potential mediator of this effect, plasma angiotensin II (AII) levels were either not measured or yielded negative results. The present investigation noted significant elevations in circulating AII in rats intubated daily with ethanol (4 g/kg) for 50 days. Animals administered ethanol only once evidenced AII concentrations equivalent with water intubated controls. Radioligand binding assay data indicated no differences in the number or affinity of Sar1,Ile8-AII binding sites in the thalamus, septum-anterior ventral third ventrical region or adrenal gland comparing those groups chronically treated with ethanol to water intubated controls. These results may support a role for the vasoconstrictive hormone AII in the etiology of alcohol-induced hypertension.

Abstract
Altered water-electrolyte status resulting from chronic alcohol dependence has been reported, although the nature of any such derangement is controversial. To illuminate this problem, four groups of rats were exposed chronically to schedule-induced polydipsia conditions with a single fluid available: 5% ethanol, 0.9% NaCl solution of 5% ethanol, 0.9% NaCl solution, or distilled water. An ad lib control group was also used. The water-electrolyte status of these groups was evaluated in two ways. First, the diuretic response to hydrochlorothiazide doses (8-12 mg/kg) was measured after 3.5 months of chronic polydipsia. Second, after approximately two additional months of polydipsia, extracellular fluid volume, as well as plasma volume and electrolytes were measured. Both alcohol-intake groups drank approximately 11.5 g ethanol/kg/day over the course of the experiment. Urinary volume response to the diuretic agent did not reveal that chronic ethanol led to either water retention or dehydration, even when extra NaCl intake was imposed chronically (NaCl-EtoH group). Animals that were overdrinking either water or the 0.9% NaCl solution had extracellular fluid volumes that were greater than the NaCl-EtOH-polydipsic group, but they were not significantly larger than ad lib controls. There were no significant differences with respect to serum electrolyte concentration measures among the groups. In conclusion, animals that drank ethanol chronically in a pattern known to produce physical dependence revealed no altered water-electrolyte status when evaluated by acute responses to a diuretic agent, a chronically-imposed extra NaCl load, or body fluid compartment and electrolyte concentration measures.

Abstract
Alcoholics during detoxification have elevated blood pressures which are related to the severity of their withdrawal symptoms. We studied the effect of a non-selective beta-blocker, timolol on symptoms, blood pressure and plasma levels of cortisol (PC), noradrenaline (NA), vasopressin (AVP) and renin activity (PRA) during alcohol withdrawal. Eighteen alcoholics, admitted for detoxification, were randomly allocated to timolol or placebo in a double blind trial. Alcohol withdrawal symptoms did not differ either before or after timolol or placebo but patients receiving timolol required less sedation with chlormethiazole. Systolic blood pressures (SBP) and pulse both fell significantly during detoxification in both groups, the change being greater with timolol. Plasma levels of cortisol, NA, AVP and PRA fell significantly, though only NA and PC correlated with initial SBP. Timolol had no effect on any of the biochemical parameters observed. The pressor response to alcohol withdrawal is reduced by beta-blockade and the height of the blood pressure is related to plasma NA and PC levels. Alcohol withdrawal hypertension is probably due to increased sympathetic activity.

Abstract
The post-intoxication state, commonly called hangover, has been known since antiquity; yet there has been little systematic research examining the signs and symptoms of hangover among the general population. The frequency and the various symptoms of hangovers, as well as the relationships between hangovers and alcohol consumption, were analyzed using a sample of 1041 adults 18 years and older living in Western New York State. Hangovers were experienced in the previous year by only about 50% of the population of heavier drinkers; the frequency was even less among those with lower alcohol consumption. Factor analysis of the various symptoms revealed significant clusters. The findings suggest that the aversive aspects of alcohol consumption, including the hangover syndrome, may deter excessive consumption; certain individuals in whom aversive reactions as hangover do not occur may be at high risk for excessive alcohol use.

Abstract
The effect of acute moderate ethanol intoxication on renin-aldosterone axis was studied in four healthy humans in normal sodium and water balance. The subjects drank ethanol 1.2 g/kg body weight during 90 minutes. A dissociation between plasma renin activity (PRA) and plasma aldosterone took place; PRA increased (p less than 0.001) and aldosterone showed a decreasing trend, which was not significant. Serum Na+/K+-ratio increased (p less than 0.001). We observed no significant change in serum osmolality, blood pressure nor heart rate. The increase (p less than 0.001). We observed no significant change in serum osmolality, blood pressure nor heart rate. The increase in PRA was probably caused primarily by dehydration due to ethanol diuresis. The dissociation between plasma aldosterone and PRA may be associated with increasing serum Na+/K+-ratio or an inhibitory action of ethanol on aldosterone secretion.

Abstract
The endocrine effects of alcohol are briefly reviewed. Alcohol enhances glucose-induced insulin secretion and may thus cause reactive hypoglycemia. However, inappropriate insulin secretion is not the reason for alcohol-induced hypoglycemia in fasted subjects. The direct effects of alcohol in thyroid function in humans are small, although alcoholics often have low concentrations of thyroid hormones in their plasma because of liver damage. Alcohol increases cortisol secretion from adrenal cortex either by increasing ACTH secretion or, more probably, by directly stimulating the adrenals. Alcohol also increases aldosterone secretion. The production of epinephrine and norepinephrine by the adrenal medulla is increased during alcohol intoxication and withdrawal. Plasma testosterone concentration is decreased during hangover and during alcohol withdrawal. The decrease is due to direct effects of alcohol on the testes, because plasma LH concentration is increased simultaneously. Alcohol has no significant effect on the LRH-induced secretion of LH. Plasma growth hormone concentration is decreased during alcohol intoxication and increased during hangover. TRH-induced secretion of prolactin is increased during alcohol intoxication and inhibited during hangover and withdrawal. The last finding suggests that there is dopaminergic overactivity in hypothalamus during alcohol withdrawal.

Abstract
The effect of ethanol intoxication and hangover on plasma renin activity (PRA), plasma aldosterone (PA) and plasma cortisol (PC) concentrations was studied in 7 healthy supine men in controlled clinical conditions during 18 h beginning at 6 p.m. Large individual variation was observed in the response of PRA, PA and PC to ethanol. Following ethanol, stimulation of PRA was observed at the 14th and the 16th hour (P less than 0.05), of PA at the 4th and the 6th hour (P less than 0.01 and P less than 0.05, respectively) and of PC at the 4th and the 14th hour (P less than 0.01 and P less than 0.05, respectively). Ethanol ingestion suppressed PC during the first hour (P less than 0.02). Water ingestion at 8 a.m. suppressed PA between the 14th and the 16th hour (8-10 a.m.) in control and ethanol experiment (P less than 0.01 and P less than 0.005, respectively). There was a dissociation between PRA and PA, but intra-individually PRA and PA correlated fairly or well. Plasma arginine vasopressin (AVP) and PC were also significantly correlated. The results suggest that changes in PA and PC as well as the dissociation of PRA and PA after ethanol ingestion might be partly related to dehydration and to the increased secretion of hypothalamic and pituitary hormones as well as to sodium and potassium balance. There was a biphasic effect of ethanol, including an inital suppression of PC and a subsequent increase of PC, PRA and PA. Upright posture appears to exaggerate the stimulating effect of ethanol on PRA, PA and PC.

Abstract
The effect of ethanol intoxication and hangover on immunoreactive plasma arginine vasopressin (AVP) concentration was studied in 7 healthy supine men in controlled clinical conditions. In 6 subjects plasma AVP increased above control values at the time of maximal blood ethanol concentration. The highest AVP values were observed in the subjects having nausea and vomiting and the worst hangover symptoms. During hangover plasma AVP values were higher than the controls and the response of plasma AVP to upright posture was exaggerated. The dissociation of plasma AVP concentration and ethanol diuresis suggested that the suppression of AVP release is not the sole determinant of ethanol diuresis. The study may indicate that the toxic effects of ethanol and the severity of hangover symptoms are associated with the state of hydration and individual sensitivity of AVP triggering mechanisms.

Abstract
One hundred and twenty-three patients, sixty-four men and fifty-nine women, with primary hypertension were studied with regard to supine and sitting blood pressure (BP), plasma renin activity (PRA) during basal and stimulated conditions, and urinary sodium and potassium excretions. The patients ranged in age from 20 to 76 (mean 48) years. A control material of 120 normotensive subjects, forty-nine men and seventy-one women, with an age range 22--78 (mean 47) years were studied during the same strictly standardized conditions. The two populations were compared statistically. The mean basal PRA level, measured after 1 h supine rest, was significantly higher in the hypertensive subjects, while the upright PRA, determined after ambulation for 3--4 h, was the same in the two groups. On the contrary, the stimulated mean PRA, measured 3--4 h after intake of 80 mg frusemide orally was significantly lower in the hypertensive subjects. No relationships could be demonstrated between PRA and the 24 h urinary electrolyte excretions. An age dependent decrease of upright and stimulated PRA was demonstrated only in the hypertensive population. Applying our previously published reference ranges for stimulated PRA, 16% of the hypertensive patients were considered to have low renin hypertension.
