    Description / Table of Contents: Zusammenfassung An weißen Mäusen wurde der Einfluß einer einmaligen (4 Std) und einer 7wöchigen, intermittierenden (35mal 9+1 mal 4 Std) Vergiftung mit Kohlenmonoxyd (0,1 Vol.- % in Luft) auf den Gehalt des Gehirns an Glykogen, Pyruvat, Lactat, ATP und Kreatinphosphat sowie den Blutzucker untersucht. Im akuten Versuch war bei einem CO-Hämoglobingehalt des Blutes von 35% der Pyruvatgehalt des Gehirns erhöht und der Blutzuckerspiegel erniedrigt. Nach 7 Wochen fanden sich bei gleichem CO-Hämoglobingehalt zusätzlich noch ein Anstieg des Lactat- und ein Abfall des Kreatinphosphatgehaltes. Die Veränderungen waren innerhalb von 15 Std Aufenthalt in CO-freier Atmosphäre nur z. T. reversibel.
    Notes: Abstract The influence of single (4 hours) or repeated (35 times, 9 hours plus once for 4 hours within a period of 7 weeks) exposure to 0.1% (v/v) carbon monoxide in air on the glycogen, pyruvate, lactate, ATP and phosphocreatine content of the brain and on the blood glucose level was investigated in mice. By a carbon-monoxyhemoglobin concentration of 35% after a single exposure to carbonmonoxide, the pyruvate content of the brain was found to be increased and the blood glucose level decreased. After 7 weeks of repeated exposure, additional changes found by the same CO-Hgb content included an increase in the lactate and a decrease in the phosphocreatine content of the brain. The changes produced by repeated carbon monoxide poisoning were found to be only partly reversibel after the animals were subsequently allowed to breathe normal air for 15 hours.

    Notes: Summary The effect of pretreatment with 340 μg/g pyrazole i.p., an inhibitor of alcohol dehydrogenase, on the changes in the carbohydrate metabolism of the liver, as produced by 4 mg/g ethanol i.v., was investigated in mice. Pyrazole completely prevented the ethanol-induced rise of the glycerol-1-phosphate content and of the glycerol-1-phosphate/dihydroxyacetone phosphate and lactate/pyruvate ratios and diminished the decrease of the hepatic pyruvate and lactate contents. This suggests, that these changes are mediated by shifts in the hepatic NADH/NAD ratio occurring during alcohol oxidation. The glycogen depleting effect of ethanol was not abolished by pyrazole showing that this effect is brought about—at least in part—by ethanol itself.
