Endplate potentials (EPP's) and miniature endplate potentials (MEPP's) were recorded from neuromuscular junctions of the mouse phrenic nerve-diaphragm preparation, blocked by high Mg++ (12 X 10(-3) mol/l)-Ringer. Superfusion of the preparations with Mg++-Ringer solutions containing thallium acetate (5 X 10(-4)...

The toxic effect of thallium added to the bath solution was studied with intra- and extracellular recordings from mammalian nerve-muscle preparations. To elucidate the target region, 3 different functional parameters were studied: (1) Post-synaptic endplate potentials (EPPs) resulting from evoked...

Thallium acetate is a known neurotoxic agent. In this study, we investigated the mechanisms by which thallium acetate induces cell cycle arrest and cell apoptosis in cultured LC6 glioma cells. Exposure of C6 glioma cells to thallium acetate decreased cell...

Thallium acetate in concentrations of 500 to 1000 mg/l is tolerated in the culture by the most mollicutes of the orders Mycoplasmatales and Acholeplasmatales and by this reason it is added in the culture media as a selective element for...

The potassium (K(+)) analogue thallium (Tl(+)) can be used as a tracer for mapping neuronal activity. However, because of the poor blood-brain barrier (BBB) K(+) -permeability, only minute amounts of Tl(+) enter the brain after systemic injection of Tl(+) -salts...
