title: [Rhythmic component of twelve hours].
abstract: From observations made on the rhythms in different systems: changes in plasmatic concentrations of 5-fluorouracil administered at a constant rate, proliferative activity of human tissues (bone marrow and oral mucosa), actometry, variations of glutathione levels in the liver and kidney from ice, we show the existence of a 12 hours rhythmic component and we discuss the putative importance of this component.
