Antioxidant effects in the quinone fraction from Auxemma oncocalyx TAUB

In previous studies in vitro we showed that the quinone fraction (QF) from the heartwood of Auxemma oncocalyx TAUB. presented antiplatelet and antioxidant activities. In the present work, the QF antioxidant property was evaluated in models of CCl(4)-induced hepatotoxicity in rats, and prolongation of pentobarbital-induced sleeping time in mice. Our results showed that levels of plasma glutamate-pyruvate-transaminase (GPT), as well as glutamate-oxalate-transaminase (GOT), were increased by the administration of CCl(4). On the other hand, only GPT levels were reduced by the QF treatment. Pentobarbital sleeping time was prolonged by the administration of CCl(4) and reduced by the QF treatment. Moreover, QF did not alter the pentobarbital-induced sleeping time. In conclusion, we showed that QF, represented mainly by oncocalyxone A, has hepatoprotective activity, and this effect is at least in part due to the antioxidant activity of this quinone.     

Influence of ozone on pentobarbital pharmacokinetics in mice

Previous studies have indicated that acute exposure to ambient concentrations of ozone (O3) as low as 196 micrograms/m3 (0.1 ppm) increases pentobarbital (PEN)-induced sleeping time in female mice. To elucidate potential mechanisms involved, additional studies were performed. A 3 h exposure to 9800 micrograms O3/m3 (5 ppm) did not affect brain concentrations of PEN at time of awakening, even though sleeping time was increased. Exposure for 3 h to 9800 micrograms O3/m3 (5 ppm) did not alter the pattern of brain or plasma metabolites of PEN. Pentobarbital clearance followed first-order kinetics with a one-compartment model. Mice exposed to 9800 micrograms O3/m3 (5 ppm) for 3 h had a 106% increase in the plasma half-life of pentobarbital; at 1960 micrograms O3/m3 (1 ppm) for 3 h, a 71% increase was observed. It therefore appears possible that PEN-induced sleeping time might be increased due to an decrease in hepatic metabolism of PEN.     

Drug interaction on antitumor drugs I. Antitumor activity of cyclophosphamide in mice consecutively administered aminopyrine, chlorpromazine, or morphine (author's transl)

Antitumor activity and lethality of cyclophosphamide alone and in combination with several drugs were investigated in male ddY mice. The antitumor activity was estimated by weighing the solid tumor on the 15th day after Ehrlich ascites cell inoculation. Pentobarbital induced sleeping time for monitoring the activity of hepatic drug-metabolizing enzymes was defined as the time between the loss and the recovery of the righting reflex. Consecutive administration of pentobarbital shortened the pentobarbital sleeping time and increased the antitumor activity after cyclophosphamide. On the contrary, a single administration of SKF 525A or cycloheximide prolonged the pentobarbital sleeping time significantly and decreased the antitumor activity after cyclophosphamide. Consecutive administration of aminopyrine, or chlorpromazine shortened the pentobarbital sleeping time and increased the antitumor activity after cyclophosphamide. These results indicate that aminopyrine and chlorpromazine may increase the levels of the hepatic drug-metabolizing components and may activate cyclophosphamide by conversion to an active form. Effect of a consecutive administration of morphine on the pentobarbital sleeping time and the antitumor activity was uncertain in individual cases.On the other hand, aminopyrine, chlorpromazine, or morphine in consecutive administration increased the lethality of cyclophosphamide.

Rat hepatic mitochondria are more sensitive to allyl alcohol than are those of mice

The hepatotoxic effects of allyl alcohol with particular reference to mitochondrial morphology and function were compared in male CD1 mice and male CD rats 24 h after 0.05 ml/kg i.p. in corn oil. As already noted by others, allyl alcohol-treated rats usually showed histologic evidence of tissue necrosis when hematoxylin-eosin-stained tissue sections were examined whereas mouse tissue sections did not. The serum glutamic pyruvic transaminase (SGPT) activities were significantly elevated in both mice and rats but to a much greater extent in the latter. Pentobarbital sleeping time was significantly increased over that of corn oil control groups in rats but decreased in mice. In rats electron microscopy showed mitochondria which contained flocculent densities. State 4 respiration was not altered by allyl alcohol in rats, but state 3 respiration was significantly depressed indicating an absence of respiratory control and an inability to perform energy coupling. In allyl alcohol-treated mice the isolated mitochondria were found to be primarily in a condensed form. Except for the effect on pentobarbital sleeping time and SGPT, no other findings were different from those in control groups given only corn oil. When the dose of allyl alcohol in mice was increased to 0.15 ml/kg in an attempt to elicit more severe signs of hepatotoxicity, there was a high mortality in the first 24 h period without histologic evidence of liver necrosis. Thus, we confirm that at equivalent doses, male rats are more sensitive to the hepatotoxic effects of allyl alcohol than are male mice, and extend the generalization to the liver mitochondria of the 2 species.
