Natural killer (NK) cells have been obtained from mouse spleens and grown in vitro. These cells: retained cytotoxicity against YAC targets; and were homogeneous as judged by morphology and surface markers. The alpha-naphthol acetate esterases (ANAE) and diisopropyl-fluorophosphate (DFP)-binding proteins of NK cells, YAC cells and NK-YAC conjugates have been(More)
1. The uptake of 3H-(+/-)metaraminol (MA) by tissue slices or pieces was studied in vitro in several peripheral rat organs of varying density of sympathetic innervation (the tissue level of endogenous noradrenaline ranging from 1.7-99.1 nmoles/g). In each individual tissue preparation amine uptake was corrected for entry into the 14C-D-sorbitol space. 2.(More)
PAPP-A is a macromolecular glycoprotein associated with human pregnancy. In vitro, PAPP-A is produced by explant cultures of trophoblast and decidua. The present work was undertaken to see if the presence of decidua had any effect on the disappearance rate of PAPP-A after removal of the placenta either by surgery or by spontaneous delivery. PAPP-A was(More)
Cytochemical investigations have associated acid inorganic trimetaphosphatase (TMPase) activity with the lysosomes of certain cell types. We have used the modified staining technique of Berg to show that this enzyme activity is present in normal mononuclear phagocytes and macrophage cell lines. We have found this enzyme activity to be present in murine(More)
Autoclaved oats were inoculated with a strain of Fusarium sporotrichioides or Fusarium poae. Moisture content of oats after inoculation was at 38%, incubation took place in standing culture at 28 °C. The A-type trichothecenes, 4,15-diacetoxyscirpenol (4,15-DAS), 15-monoacetoxyscirpenol (15-MAS), and scirpentriol (SCIRP) were analyzed by GC/MS. For each(More)
