Golgi fractions from livers of control and ethanol-intoxicated rats. Enzymic and morphologic properties following rapid isolation

J J Bergeron. Biochim Biophys Acta. .

Abstract

Following rapid isolation, it has been found that Golgi apparatus from ethanol-intoxicated animals contain high levels of galactosyltransferase but also detectable glucose-6-phosphatase and microsomal esterase, as well as 5'-nucleotidase activity. In experiments carried out in parallel on littermate animals but without intoxication, similar recoveries and specific activities of the four enzymes were observed. Morphologic analysis of Golgi fractions isolated from control animals demonstrated no striking morphologic difference to those from the ethanol-intoxicated animals. Indeed, using galloyl glucose-lead staining techniques to mark the lipoprotein particles in situ, it was found that all Golgi apparatus of hepatocytes from control animals were marked by very low density lipoprotein particles. It is therefore concluded that within the limits of the present analyses, Golgi fractions isolated from control animals are as valid as those isolated from ethanol-intoxicated rats.
