Induction of alcohol withdrawal symptoms by nalorphine in chronic alcoholic patients.

The effect of nalorphine on eliciting symptoms of either alcohol or narcotic withdrawal was studied. Five male alcoholics were challenged with nalorphine and saline, both while sober and during alcohol ingestion. After nalorphine, pulse rate decreased in patients when sober, but increased when they were ingesting alcohol. Nalorphine administration resulted, during alcohol ingestion, but not in the sober state, in lacrimation, a symptom of narcotic withdrawal, in one patient, and in the following symptoms of alcohol or narcotic withdrawal in one or more patients: weakness, anorexia, insomnia, disorientation, and tremor. These findings suggest that morphine-like alkaloids play a role in the mediation of alcohol withdrawal symptoms.

Alcoholic hepatitis. Cell-mediated immunological response to alcoholic hyalin.

Immunological reactivity in alcoholic hepatitis has bben attributed to alcoholic hyalin, the histological hallmark of this disease. A purified isolate of alcoholic hyalin with electron microscopic, biochemical, and serological characteristics documented previously was added to lymphocytes from healthy subjects and patients with alcoholic hepatitis or other hepatic disorders. Production of migration inhibition factor (MIF) in response to this material was used as an index to lymphocyte reactivity. MIF was significantly increased in lymphocytes obtained from patients with alcoholic hepatis, as compared to the healthy controls (P less than 0.001), and persons with other liver diseases (P less than 0.005). These observations indicate that immunological hyperreactivity to alcoholic hyalin occurs in patients with alcoholic hepatitis; such activity may be of key importance in the pathogenesis or sequelae (or both) of this disease.

The effect of cues of quantity visible and preference on drinking by alcoholic and non-alcoholic subjects.

When a glass (150 ml) of a preferred/non-preferred orange drink was visible alcoholic subjects drank less than non-alcoholics. When a glass+jug (900 ml) was visible the alcoholics drank significantly more than the non-alcoholics. The cues of quantity visible and preference had an additive effect on the alcoholics' consumption. The experiment was modelled on a study by Nisbett (1968 a) concerned with cues controlling food intake in obese and non-obese subjects. An analogy was drawn between overeating by the obese and overdrinking by alcoholics.

Alcoholism and depression in adopted-out daughters of alcoholics.

Forty-nine daughters of alcoholics were compared to 47 daughters of nonalcholics; both groups of women (average age, 35 years) had been adopted by nonrelatives early in life. Two women in each group were alcoholic or problem drinkers. Although this is above the expected rate of alcoholism among women, the numbers are too small to draw definite conclusions. Almost all were light drinkers. Daughters of alcoholics had no more depression than controls, indicating that alcoholism in the biological parents did not increase the risk of depression in daughters raised by foster parents. Environmental factors may be important in both alcoholism and depression in women, since both tended to be correlated with psychopathology in the foster parents.

Kinetics and reaction mechanism of yeast alcohol dehydrogenase with long-chain primary alcohols.

Kinetic studies of yeast alcohol dehydrogenase with NAD+ and ethanol, hexanol or decanol as substrates invariably result in non-linear Lineweaver-Burk plots if the alcohol is the variable substrate. The kinetic coefficients determined from secondary plots are consistent with an 'equilibrium random-order' mechanism for extremely low alcohol concentrations and for all alcohols, the transformation of the ternary complexes being the rate-limiting step of the reaction. This mechanism also applies to long-chain substrates at high concentrations, whereas the rate of the ethanol-NAD+ reaction at high ethanol concentrations is determined by the dissociation of the enzyme-NADH complex. The dissociation constants for the enzyme-NAD+ complex and for the enzyme-alcohol complexes obtained from the kinetic quotients satisfactorily correspond to the dissociation constants obtained by use of other techniques. It is suggested that the non-linear curves may be attributed to a structural change in the enzyme itself, caused by the alcohol.

Alcoholic hepatitis with and without alcoholic hyaline.

Sixteen cases of alcoholic hepatitis with alcoholic hyaline (Group I) and 13 cases without alcoholic hyaline (Group II) have been collected since 1970. These were most frequently found in the fifth decade in both groups. One female was found in Group I. Cases of about two-thirds of both groups were comsumers of 110 g or more of alcohol per day. No significant differences except fever and erythrocyte sedimentation rate were found in clinical and laboratory changes between both groups. Fatty change in liver biopsy specimens were more frequently seen in Group I than in Group II. The wedged hepatic venous pressure was markedly elevated in alcoholic hepatitis with cirrhosis and moderately elevated in alcoholic hepatitis without cirrhosis. Wedged hepatic venography showed the main portal trunk and extrahepatic collaterals, namely, reversal of the portal flow or such tendency in 2 out of 5 patients of Group I.

Continuities in the olfactory deficits of chronic alcoholics and alcoholics with the Korsakoff syndrome.

Olfactory dysfunction, a finding prevalent among alcoholic Korsakoff patients, was investigated in long-term alcoholics with Korsakoff's Syndrome. The results demonstrate that alcoholics are impaired on odor quality discrimination but performed normally on complex hue discriminations. These findings support the hypothesis that chronic alcoholics and alcoholic Korsakoff patients represent two points on a single continuum of cognitive deterioration associated with alcohol abuse.

Auditory brain stem potentials in chronic alcohol intoxication and alcohol withdrawal.

Auditory brain stem evoked responses were in unrestrained rats during periods of acute and chronic alcohol intoxication, alcohol withdrawal, and recovery. Acute alcohol administration altered the auditory brain stem potentials by a prolongation of both peak latency and central conduction time, beginning with early peaks. Similar but lesser effects affecting only the latter peaks were observed during chronic alcohol intoxication. By contrast, alcohol withdrawal resulted in a decrease in the peak latencies of auditory brain stem potentials and a facilitation of central conduction time. Recovery of the auditory brain stem potentials to the normal form required at least three to four weeks. The present study provides the first quantitative data, to our knowledge, on manifestations of alcohol tolerance and withdrawal.

Difference of hepatic circulation between alcoholic and non-alcoholic hepatic cirrhosis.

Comparisons were made of hepatic circulation between alcoholic and non-alcoholic cirrhosis. The wedged hepatic venous pressure and per cent intrahepatic shunt measured by the method of continuous infusion of D-galactose-1-14C were similarly markedly increased. On the other hand, the wedged hepatic venography showed the main portal trunk and extrahepatic collaterals, namely, the tendency of reverse or stagnant portal flow, more frequently in alcoholic cirrhosis than in non-alcoholic cirrhosis. The nodules shown by slow low-pressure hepatic sinusoidography were larger in non-alcoholic cirrhosis than in alcoholic cirrhosis.

Use of Michigan Alcoholism Screening Test with hospitalized alcoholics, psychiatric patients, drinking drivers, and social drinkers in New Zealand.

The Michigan Alcoholism Screening Test (MAST) has been validated on a wide range of American drinkers. In this study the MAST was administered to four groups of New Zealand males: 100 hospitalized alcoholics, 100 psychiatric inpatients, 70 convicted drinking drivers, and 55 social drinkers. All the diagnosed alcoholics scored in the test's alcoholic range, as did 83% of the drinking drivers. Seventy-six percent of psychiatric patients and 89% of social drinkers scored below 5. The MAST appears to be a valid instrument for use under New Zealand conditions, but the ability to discriminate between alcoholics and problem drinkers would be an added advantage.

Alcoholics Anonymous, alcoholism counseling, and social work treatment.

The authors suggest that the misunderstanding by many social workers of the particular values of Alcoholics Anonymous and the skills of alcoholism counselors can involve alcoholic patients themselves in the stress of reconciling different approaches to treatment. They call upon all who treat alcoholics to build mutual trust and cooperation on two assumptions basic to all forms of treatment-that alcoholism is a disease and abstinence is essential to recovery.

Alcoholism and ethnicity: a comparative study of alcohol use patterns across ethnic groups.

Sociological and alcohol use patterns were studied in American Indian, Black, Hispano, and White Anglo groups of alcoholism patients. Sociological variables indicated all groups appeared to be experiencing significant disruption in social and vocational areas, with the American Indian group showing the greatest disruption across the four groups in the socioeconomic areas. The four groups did not differ as to use of alcohol to enhance self, manage anxiety and depression, or as to sustained or periodic use. American Indians and Hispanos have a greater tendency to drink gregariously, to drink more, and to have more disruption in social role functioning. The general trend was that the American Indian group revealed greater social and alcohol symptom disruption than the other three groups, thus supporting a more specialized treatment approach for American Indian alcoholism patients.

[Significance of several factors for actualization of the pathologic drive to alcohol in chronic alcoholism].

On the basis of literary data and clinical experience, a list of 27 factors was compiled, which could have a significance for actualizing pathological drives to alcohol in chronic alcoholism. The factors were marked under such headings as "individual", "family-environmental" and "connected with the environment at work". In order to establish the connection of each factor with the actualization of a pathological drive to alcohol, 200 inpatients treated for chronic alcoholism were examined. A comparative analysis was performed for eliminating the significance of factors for groups of patients with different stages of the disease and premorbid personality types. The possibility of using these data in clinical practice and preventing relapses in the treatment of chronic alcoholism is assessed.

[Primary alcoholic cardiac disease and alcoholic liver disease. Anatomopathological study].

In order to find out if there is an association between alcoholic heart disease and alcoholic liver disease, and to discover the prevalence and characteristics of anatomical findings in the heart at alcoholic subjects, a prospective study was realized during the autopsies of patients younger than 60 years old, who had died with alcoholic liver disease not associated with an obvious heart disease. A second group of subjects containing similar characteristics of the first group, only without a past history of alcoholism nor liver disease, were used as controls. The comparison between the two groups in respect to: age, nutritional status, macroscopic and microscopic findings of the heart, frequency and degree of atherosclerosis revealed no statistical difference. In conclusion, we submit that the subjects who had died from liver disease also presented myocardial alterations, but that these did not differe from those observed in the control subjects.

Alcohol dehydrogenase (ADH) in yeasts. II. NAD+-and NADP+-dependent alcohol dehydrogenases in Saccharomycopsis lipolytica.

In Sm. lipolytica one NAD+-dependent and three NADP+-dependent alcohol dehydrogenases are detectable by polyacrylamide gelelectrophoresis. The NAD+-dependent ADH (ADH I), with a molecular weight of 240,000 daltons, reacts more intensively with long-chain alcohols (octanol) than with short-chain alcohols (methanol, ethanol). The ADH I is not or only minimally subject to glucose repression. Besides the ADH I band no additional inducible NAD+-dependent ADH band is gel-electrophoretically detectable during growth of yeast cells in medium containing ethanol or paraffin. The ADH I band is very probably formed by two ADH enzymes with the same electrophoretic mobility. The NADP+-dependent alcohol dehydrogenases (ADH II--IV) react with methanol, ethanol and octanol with different intensity. In polyacrylamide gradients two bands of NADP+-dependent ADH are detectable: one with a molecular weight of 70,000 daltons and the other with 120,000 daltons. The occurrence of the three NADP+-dependent alcohol dehydrogenases is regulated by the carbon source of the medium. Sm. lipolytica shows a high tolerance against allylalcohol. Resistant mutants can be isolated only at concentrations of 1 M allylalcohol in the medium. All isolates of allylalcohol-resistant mutants show identical growth in medium containing ethanol as the wild type strain.

An inborn alcohol tolerance in alcohol-preferring rats. The lack of relationship between tolerance to ethanol and the brain microsomal (Na+K+) ATPase activity.

Alcohol tolerance, measured as performance on the tilting plane after ethanol injection (2.5 g/kg body weight i.p.), was examined in the AA strain of rats which voluntarily drink large amounts of alcohol, in the ANA strain which drink very little alcohol, and in ordinary albino rats which consume intermediary amounts of alcohol. The AAs showed the highest innate ethanol tolerance; the ANAs had the lowest innate tolerance. After chronic alcohol administration, both AA and ANA strains increased their tolerance, but the AAs remained superior to the ANAs. The chronic ethanol treatment did not significantly change the (Na+K+) ATPase activity of the crude microsomal fraction of the brains of the strains.

Identiy of brain alcohol dehydrogenase with liver alcohol dehydrogenase.

A method for obtaining electrophoretically homogeneous rat liver alcohol dehydrogenase (EC 1.1.1.1) at a specific activity of 2-2.5 mumol/min per mg of protein is presented. Anti-sera prepared against the purified enzyme inhibit alcohol dehydrogenase by up to 75% and cause precipitation of virtually all the enzyme. The antisera were shown by immunoelectrophoresis of a partially purified liver homogenate to be specifically directed against alcohol dehydrogenase and were used to demonstrate that the alcohol dehydrogenases of rat brain and liver share common antigens. The total activity of alcohol dehydrogenase in rat brain homogenates is normally quite low, with as much as 10% of the total activity attributable to the activity in the blood contained within the brain; in cases of severe liver damage (induced experimentally with carbon tetrachloride) this contribution may rise to as much as 60%.

Alcohol dehydrogenase mutants of Chinese hamster somatic cells resistant to allyl alcohol.

Alcohol dehydrogenase (alcohol: NAD oxidoreductase, E.C. 1.1.1.1.) mutants of Chinese hamster somatic cells were isolated as resistant to allyl alcohol (ALLR). The ALLR phenotypes of the mutant clones were reproducible with high fidelity and stable over long intervals of growth in the absence of the selecting drug. Several mutants, Adh-1, Adh-2, Adh-9 and Adh-13, resistant to allyl alcohol were characterized. They have between 15 and 40% of the alcohol dehydrogenase activity of the wild-type cell lines. This phenotype is therefore a useful marker to analyze gene segregation of somatic cell mutations and to study the expression of the genes involved in the metabolism of ethanol in mammalian cells.
