Acetylcholine metabolism and choline uptake in cortical slices

The uptake of [14C]choline was studied in cortical slices from rat brain after their incubation in a Krebs-Henseleit medium containing either 4.7 mM-KCl (low K), 25 mM-KCl (high K) or 25 mM-KCl without calcium (Ca free, high K). With 0.84 μM-[14C]choline in the medium the uptake per gram of tissue was 0.62 nmol after incubation in low K medium,...

Radiosensitization of mammalian cells by diamide

The effect of diamide on the radiosensitivity of T cells was investigated under oxic and anoxic conditions. The compound was found to sensitize the cells under both conditions. Under oxic conditions, exposure for 10 min before and during irradiation to 0.1, 0.5 and 1.0 mM diamide produced dose modifying factors of 0.81, 0.60 and 0.55,...
