Quantitative comparison of maternal ethanol and maternal tertiary butanal diet on postnatal development

Authors: Daniel, MA; Evans, MA (1982) Journal of Pharmacology and Experimental Therapeutics 222:294-300. HERO ID: 11705

[Less] The mechanism by which developmental anomalies associated with the fetal alcohol syndrome are produced . . . [More] The mechanism by which developmental anomalies associated with the fetal alcohol syndrome are produced is not understood. Current hypotheses include altered maternal function and direct action of ethanol or its metabolic product, acetaldehyde, on embryonic tissue. Pregnant mice were fed liquid diets containing either ethanol (3.6%, w/v) or tertiary butanol in concentrations of 0.50, 0.75 and 1.00% (w/v) from day 6 to day 20 of gestation. Untreated surrogate maternal animals were substituted in half of the original litters to gain insight into the role played by maternal nutritional and behavioral factors. Quantitatively, t-butanol was approximately 5 times more potent than ethanol in producing a developmental delay in post-parturition physiological and psychomotor performance scores. The existence at significant postnatal maternal nutritional and behavioral factors affecting lactation and/or nesting behavior were also evident at the higher concentrations of alcohol. The results from this study are consistent with the hypothesis that ethanol per se and not acetaldehyde is primarily responsible for the fetal alcohol syndrome.

Circadian patterning of feeding, drinking and activity during diurnal food access in rats

[More] Using an "ecologically" relevant approach, the present study investigated (1) the association between feeding and drinking patterns and their circadian organization and (2) changes in general activity (or life-style), during ad lib conditions (fa:LD) and in a situation where access to food was restricted to the light phase (fa:L). Rats were housed in large outcages with nest boxes. Feeding, drinking, activity, outcage and nest occupation were recorded automatically throughout the day-night cycle. Access to food was restricted by a sliding door situated in front of the food hopper. Under ad lib conditions rats were mainly nocturnal, eating 94% and drinking 95% of their daily intakes at night. The patterns of food and water intake were similar, showing a bimodal distribution over the dark phase. During fa:L rats showed an initial large peak in feeding with lights on, followed by a long pause. Thereafter, feeding activity was variable but remained at a low level. The nocturnal drinking pattern persisted. However, 17.5% of daily water intake was meal-associated, compared with 71% during ad lib. Diurnal activity was associated with feeding and nocturnal activity with drinking. Nocturnal outcage and nest occupation patterns were not shifted to the light phase. The experiment demonstrates that rats on an fa:L schedule reduce food and water intake, and body weight, while still retaining circadian characteristics in the temporal distribution of drinking, activity, outcage and nest occupation. Further, although feeding and drinking may be causally related they need not occur in close temporal association. The rapidity of re-establishment of the normal feeding pattern, on return to free-feeding, and the close association with drinking under normal conditions, suggest the existence of a single or two coupled oscillators controlling feeding and drinking.

Oxidative demethylation of t-butyl alcohol by rat liver microsomes

Authors: Cederbaum, AI; Cohen, G (1980) Biochemical and Biophysical Research Communications 97:730-736. HERO ID: 85713

[Less] HEEP COPYRIGHT: BIOL ABS. tert-Butyl alcohol was used experimentally as a non-metabolizable alcohol. . . . [More] HEEP COPYRIGHT: BIOL ABS. tert-Butyl alcohol was used experimentally as a non-metabolizable alcohol. It served as a substrate for rat liver microsomes and was oxidatively demethylated to yield formaldehyde. Apparent Km (methylation constant) for t-butanol was 30 mM while Vmax was about 5.5 nmol/min per mg microsomal protein. Formaldehyde production was stimulated by azide, which prevented destruction of H2O2 by catalase. Hydroxyl radical scavenging agents, such as benzoate, mannitol and 2-keto-4-thiomethylbutyrate suppressed formaldehyde production. Microsomal reaction pathway involved interaction of t-butanol with hydroxyl radicals generated from H2O2 by microsomes. Formaldehyde was produced when t-butanol was incubated with model hydroxyl radical-generating systems such as Fe-EDTA-stimulated oxidation of xanthine by xanthine oxidase or Fe-EDTA-catalyzed autoxidation of ascorbate. t-Butanol apparently cannot be used to distinguish metabolically-linked from non-metabolically-linked actions of ethanol.

Quantitative comparison of physical dependence on tertiary butanol and ethanol in mice: Correlation with lipid solubility

Authors: McComb, JA; Goldstein, DB (1979) Journal of Pharmacology and Experimental Therapeutics 208:113-117. HERO ID: 699330

[More] Mice were made physically dependent on t-butanol and the withdrawal reaction was compared quantitatively with that produced by ethanol. The mice inhaled t-butanol vapor (50-140 mumol/1 of air) continuously for 1, 3, 6 or 9 days. Daily t-butanol blood levels were determined by gas chromatography, using ethanol as internal standard. After t-butanol exposure the mice were removed from the vapor chamber and the withdrawal reaction was quantitated by hourly scoring of convulsions elicited by handling. The peak of the withdrawal reaction occurred 3 to 5 hr after the mice were removed from the t-butanol vapor. The intensity of the withdrawal reaction increased with the duration of inhalation, and with the t-butanol blood levels maintained during the intoxication period. The withdrawal syndrome was qualitatively similar to that produced by ethanol. Quantitatively, t-butanol was 4 to 5 times more potent than ethanol in producing physical dependence. Since t-butanol is about 4 to 5 times more lipid soluble than ethanol, the data are consistent with a cell membrane site for alcohols in producing physical dependence.

Adult Syrian hamsters (Cricetus auratus) are relatively insusceptible to the lethal affect of the ETBE virus after peripheral inoculation. After subcutaneous infection with 10(3) i. cer. mouse LD50 of the virus they manifest 25 per cent mortality. 2) In subcutaneously infected hamsters the virus is demonstrable in the CNS of only 20 per cent of the animals. CF- and VN-antibodies can be found in the blood from the 10th day; CF--antibodies culminate on the 20th-30th day receding relatively quickly, whereas VN-antibodies peak after the 28th day, dropping only partly and persisting. 3) The dynamics of CF- and VN-antibodies and a high number of clinically inapparent hamster infections resemble the situation in humans infected with ETBE under natural conditions.

Inapparent infection was called forth in M. rhesus monkeys by means of subcutaneous inoculation of ETBE virus. 2. Viremia was found in 18 (86 per cent) of 21 monkeys. In all the 18 monkeys, specific virus-neutralizing antibodies were found; in 17 of them complement-fixing antibodies developed in addition. 3. Neutralizing antibodies (N greater than or equal to 1.7 log10) were first recorded on 10th day with a peak on 32nd day, retaining, after a small decrease, a relatively high level in all reacting animals. 4. Complement-fixing antibodies were first found on 18th day, showing a peak on 22nd day whereafter they dropped considerably or even disappeared so that on 150th day they were present in a low titre in only 35 per cent of the originally reacting monkeys. 5. The findings were compared with the situation in naturally infected humans and in hamsters infected inapparently (experimentally) with ETBE virus.

[More] The reactions of human hemoglobin A with methyl, ethyl, n-propyl, n-butyl, iso-butyl, sec-butyl, and tert-butyl isocyanide were examined in the presence and absence of inositol hexaphosphate. As the size and bulk of the aliphatic side-chain increases, the relative association rates and affinities of the beta-chains for isonitriles increase compared to those of the alpha chains. This result indicates that the beta heme pocket within hemoglobin is more open and accessible to ligand molecules than the alpha heme pocket.
