Social play between two rhesus monkey (Macaca mulatta) infants takes place mainly when they are both not in body contact with their mothers. This suggests that social play and mother-infant body contact are potential competitors in the infants' time budgets. We investigated whether the presence of a playmate changed the duration of mother-infant...

The subacute inhalation toxicity of ??-ethylacrolein was examined in rats by repeated exposure of 4 groups of 10 males and 10 females each to ??-ethylacrolein vapour at concentrations of 0, 2.0, 9.8 or 48.4 ppm, respectively, (6 h/day, 5 days/week) for a period of 13 weeks. The effects at 48.4 ppm were found to include growth retardation, focal...

The effects of etiracetam, a structural analogue or piracetam, were investigated in rats on Y-maze discrimination acquisition, on open field behavior, on one-trial passive avoidance learning and on shuttlebox acquisition and extinction. The results indicate that this drug significantly enhances acquisition and may improve retention without...

Immunohistochemically, coagulation F-VIII-R:AG in vascular endothelial cells can be demonstrated with antihuman F-VIII-R:AG antisera after fixation with 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide, using both peroxidase and fluorescence techniques. The generally used aldehyde containing fixatives, result in a loss of immunoreactivity....

Flow cytometry was used to measure the uptake of adriamycin (AM) and daunomycin (DM) by various cell types of the haemopoietic organs and by acute myeloid leukemia (AML) cells. For this purpose, the spontaneous fluorescence of the drugs upon excitation with laser light at 488 nm was measured. The difference in the uptake of these two drugs...

The clearance of five radioactively labeled test substances - polyvinylpyrrolidone, colloidal albumin, antimony sulfur colloid, endotoxin, and heparin - by the reticuloendothelial system was studied after i.v. injection of these substances into rats. The participation of parenchymal, Kupffer, and endothelial liver cells could be determined after...
