[Changes in liver metabolism following a standardized skin burn and intraperitoneal injection of a burn toxin isolated from burned mice skin. Studies on rat liver using isolation perfusion].

Parameters of liver metabolism were studied in the isolated perfused rat liver 5 days after a standard skin burn or an i.p. injection of a specific cutaneous burn toxin. Decreased values of the energy quotient ATP/ADP compared with normal controls were found. The absolute content of adenonucleotides was unchanged. The excretion of glucose and urea was also decreased in both groups and glucose synthesis after a lactate load was only slightly stimulated. The results show a direct influence of a burn toxin on hepatic metabolism suggesting a possible disturbance of oxydative phosphorylation.

The isolation and characterization of some vibrio parahaemolyticus strains isolated from salted herring and roe.

390 food samples (frozen, Kippered herring, Salted roe, fresh carp and salted ham) were investigated for the presence of Vibrio parahaemolyticus. 8 V. parahaemolyticus strains were isolated from herring (6.2%) and roe samples (1.3%). Some biochemical characteristics are discussed. In food borne outbreaks, presence of V. parahaemolyticus must be investigated, especially when the epidemiologically incriminated food is fish or fish products.

Studies on isolated subcellular components of cat pancreas. I. Isolation and enzymatic characterization.

Pancreas of the cat was fractionated into its subcellular components by centrifugation through an exponential ficoll-sucrose density gradient in a zonal rotor. This enables a preparation of four fractions enriched in plasma membranes, endoplasmic reticulum, mitochondria and zymogen granules, respectively. The first fraction, enriched by 9- to 15-fold in the plasma membrane marker enzymes, hormone-stimulated adenylate cyclase, (Na+K+)-ATPase, and 5'-nucleotidase, is contaminated by membranes derived from endoplasmic reticulum but is virtually free from mitochondrial and zymogen-granule contamination. The second fraction from the zonal gradient shows only moderate enrichment of the above marker enzymes but contains a considerable quantity of plasma membrane marker enzymes and represents mostly rough endoplasmic reticulum. The third fraction contains the bulk of mitochondria and the fourth mainly zymogen granules as assessed by electron microscopy and marker enzymes for both mitochondria and zymogen granules, namely succinic dehydrogenase, trypsin and amylase. Further purification of the plasma membrane fractions by differential and sucrose step-gradient centrifugation yields plasma membranes enriched 40-fold in basal and hormone-stimulated adenylate cyclase and (Na+K+)-ATPase.
