The acute, subacute and chronic toxicity of dl-1- (4-amino-3-chloro-5-trifluoromethyl-phenyl)-2-tert.-butyl-amino-ethanol hydrochloride (mabuterol), a new beta 2-selective adrenoceptor stimulant, was studied in mouse, rat, rabbit and dog. The acute oral LD50 was between 199.9 and 319.3 mg/kg in all four species used and did not differ significantly between the sexes. Intravenous LD50 was between 18.3 and 51.1 mg/kg (four species), i.p. between 60 and 78.3 mg/kg and s.c. between 113 and 125.7 mg/kg (mouse and rat only). In subacute and chronic studies in Wistar rats, mabuterol was dosed by gavage at 0, 10, 20, 40, 80 and 120 mg/kg for 1 month, and 0, 1, 2.5, 10 and 40 mg/kg for 3 (interim) and 6 months or in food at 0, 2.5, 10 and 40 mg/kg for 6 (interim) and 12 months. Beagle dogs were dosed by gelatine capsule with 0, 0.05, 0.5, 5 and 50 (25) mg/kg for 6 (interim) and 24 months. In rats, 1 and 2.5 mg/kg were well tolerated. At 10 mg/kg and above, irritability and hypersalivation were seen dependent on dose. Two males and one female given 120 mg/kg died from the test substance. In dogs, 0.05, 0.5 and 5 mg/kg were well tolerated. 50 mg/kg caused vomiting, diarrhoea, tonic-clonic convulsions and increased salivation. One male had to be killed because of severe convulsions. At term, 3 of 56 female rats of the one-year study had benign mesovarian leiomyomas. No other substance-related changes were discovered but all findings belonged to the spontaneous pathology of rat and dog, respectively.(ABSTRACT TRUNCATED AT 250 WORDS)

College students in Oklahoma completed a self-administered questionnaire to compare the drinking behaviors of culturally active American Indians (N = 34 men and 24 women) an Whites (N = 181 men and 250 women). Significantly more Indians were classified as drinkers, but they had begun drinking at a somewhat later age. Both groups indicated a preference for beer, and they were quite similar in quantity and frequency of beer consumption. White students reported drinking significantly more wine and distilled spirits, and drinking more often in public places, such as bars, pubs, restaurants and parked cars; Indians drank more in their own homes and in the homes of friends. White students tended to cite hedonistic reasons for drinking whereas Indians reported escapist or social reasons and drinking to "get high." Drinking-related problems were reported somewhat more often by Indian students, notably so by Indian women. Indians were more inclined to report the more serious drinking problems of being arrested, blacking out, interference with school or work, an difficulties in human relationships. White students more often cited problems of nausea or vomiting, drinking and driving, doing something that was later regretted and damaging property. It was suggested that the higher Indian arrest rate could be indicative of police bias and that the reports of problem drinking among Indian women be investigated further.

Alcoholic ketoacidosis is a common condition which occurs predominantly in chronic alcoholics. The usual picture is an interval of increased ethanol intake followed by one or more days of abdominal pain, vomiting, dehydration and a marked decrease in caloric intake. Acidosis is frequently as severe as in diabetic ketoacidosis, but the serum Acetest measurement of ketones may be negative or only slightly positive because of the predominance of beta-hydroxybutyrate compared with acetoacetate. Treatment with intravenous glucose and saline are the essentials of management. Insulin, bicarbonate and phosphate are usually not needed. The major cause of morbidity and mortality is not the acidosis but rather failure to adequately treat concurrent medical or surgical conditions.

A total of 70 patients presenting with suspected acute trazodone poisoning were notified to the Poisons Unit (National Poisons Information Service for England) from August 1980 until March 1983. Detailed follow-up information was obtained on 41 patients, 22 of whom were thought to have ingested trazodone alone. In these latter patients drowsiness (11), ataxia (5), nausea/vomiting (4) and dry mouth (2) were the manifestations of toxicity reported most frequently, only 2 patients became unconscious (grade 2 or 3 coma), and all recovered uneventfully with no more than minimal supportive therapy. The presence of trazodone was confirmed in 8 out of 9 patients from whom specimens (blood and urine) were received. The highest plasma trazodone concentrations (15 and 19 mg/l, respectively) were both associated with only drowsiness and ataxia. However, in 2 further patients moderate plasma trazodone concentrations (4.2 and 8.2 mg/l, respectively) were associated with deep (grade 3-4) coma, although 1 of these latter patients had also ingested ethanol (plasma concentration 3.0 g/l). Although acute trazodone poisoning does not appear to be associated with cardiac arrhythmias or convulsions, these results emphasise that drowsiness and ataxia are commonly encountered, while coma may occur in severe cases. The possible contribution of metabolites of trazodone to toxicity and the potentiating effect of co-ingested drugs or alcohol must be remembered.

Physical dependence on ethanol was produced in four rhesus monkeys by IV ethanol administration every 8 h. Ethanol was administered on each occasion until the eyeblink reflex was lost. Evidence of physical dependence development, in the form of tremoring 8 h after an infusion, appeared on day 8 of chronic administration. Abrupt cessation of ethanol administration following 16 days of chronic administration was accompanied by moderate to severe tremoring, retching, vomiting, and one or more convulsions. Peak withdrawal occurred between 12 and 32 h after abrupt discontinuation of ethanol administration, and decreased over a period of 64-204 h. Ethanol dependence was then reinstated. Once every 3-4 days, ethanol was withheld for 16 h. Withdrawal signs were scored for the first 12 h of this period, and then a test dose of ethanol, phenobarbital, or baclofen was administered. Withdrawal or intoxication signs were scored over the next 4 h, at which time ethanol administration was resumed. Both ethanol and phenobarbital suppressed ethanol withdrawal signs in a dose-related manner, and produced dose-related intoxication. Baclofen was largely ineffective in reducing withdrawal-induced tremors, although it was capable of producing sedation of a different type than that produced by phenobarbitol and ethanol.

The purpose of this paper is to review the acid-base abnormalities in patients presenting with metabolic acidosis due to acute ethanol ingestion and to review the theoretical constraints on ethanol metabolism in the liver. Alcohol-induced acidosis is a mixed acid-base disturbance. Metabolic acidosis is due to lactic acidosis, ketoacidosis and acetic acidosis but the degree of each varies from patient to patient. Metabolic alkalosis is frequently present due to ethanol-induced vomiting. However, it could be overlooked because of an indirect loss of sodium bicarbonate (as sodium B-hydroxybutyrate in the urine). Nevertheless, the accompanying reduction in ECF volume may play an important role in the pathogenesis of alcoholic acidosis because it could lead to a relative insulin deficiency. Treatment of alcohol acidosis should include sodium, chloride, potassium, phosphorus, magnesium and thiamine replacements along with attention to concomitant clinical problems. Unless hypoglycemia is present, glucose need not be given immediately. We feel that insulin should be withheld unless life-threatening acidemia is present or expected. Lastly, alcohol need not be detected on admission to make the diagnosis of this metabolic disturbance. However, when present, it could contribute directly to the lactic, acetic and B-hydroxybutyric acidoses. With respect to the theoretical constraints on ethanol metabolism, it appears that "overproduction" of NADH in the liver is best averted by converting ethanol to B-hydroxybutyric acid.

Twenty seven patients, inspected by endoscope, and diagnosed as having the Mallory-Weiss syndrome, have been studied taking into account their age, sex, background, clinic presentation, manifestations, number of lacerations, associated lesions and evolution. Twenty three of them were males and 4 females. The age average was 46.7 years. Only 8 patients had intra-abdominal increased pressure, suffering retching and vomiting 7 of them, while one had a cough access. Out of the 21 patients that we controlled, 9 were chronic alcoholism while 3 had ethanol intoxication previously. Immediate prior ingestion of salicylates had taken place in 6 patients. The clinical presentation of 22 of them was gastrointestinal bleeding, that is, 4.9% of all the upper endoscopies carried out within the bleeding patients. Single laceration was present in 22 cases, double one in 4, and triple in 1. We have frequently found endoscopy lesions associated, the most common one (37%), was hiatal hernia. They all were medically treated except one, who was operated because of gastric perforation was associated. Just one of the Mallory-Weiss syndrome patient died, due to an associated diffused bleeding gastritis.

The clinical use of alcohol to delay premature labor is critically reviewed. The evidence indicates that this procedure is no more effective in arresting preterm labor than placebo, i.e., bed rest. The rational for the clinical use of alcohol in obstetrics is also questionable. Furthermore, increasing evidence indicates that the blood alcohol levels associated with this method often causes nausea, vomiting, and headaches in mothers and can cause deleterious effects in the fetus, including death.

Transcatheter injection of absolute ethanol into the renal artery is an effective method of producing renal ablation. There has been no evidence of inadvertent damage to vessels or tissues remote from the target organ. The "postembolization syndrome" of pain, nausea, vomiting, and fever is minimal when compared with other methods of renal artery occlusion. Multiple mechanisms of action of intraarterial ethanol are proposed, including perivascular tissue toxicity, sludging of erythrocytes in small arteries, small artery spasm, and endothelial damage. Experience with this technique in six patients has resulted in specific recommendations regarding the amount and method of injection of ethanol. Angiographic criteria indicating adequate renal ablation are described.

To evaluate the toxic effect of ethanol on erythropoiesis in alcoholic ketoacidosis (AK), 6 male patients were studied in the acute and remittent phase of AK. Episodes of metabolic acidosis in nondiabetic chronic alcoholics were associated with protracted vomiting and prolonged intestinal symptoms. AK was associated with elevated beta-hydroxybutyrate, acetoacetate and lactate/pyruvate plasma levels. Analysis of plasma lipids showed raised HDL cholesterol, fatty acids and phospholipids resulting in a concomitant disorder of lipid metabolism in red cell ghosts. A red cell metabolic disorder with reduced ATP and glutathione levels was also observed in patients suffering from mild hemolytic anemia. On admission, miscellaneous toxic effects on erythropoiesis were detected when bone marrow was aspirated. This study lends further support to the hypothesis that there is a linkage of different factors producing serious but transient hematologic and oncologic implications of ethanol in patients with AK.
