title: [Chronotoxicity of cyclophosphane under different lighting conditions].
abstract: Study of the chronotoxicity of cyclophosphamide injected to mice at 18, 24, 6 and 12 o'clock has shown that animals kept under the conditions of natural changes of day and night showed the circadian rhythm of the drug toxicity with the maximal survival of the animals after injection at 24 and 6 o'clock and with the minimal survival after injection at 18 o'clock. In animals maintained under the conditions of artificial constant light the toxicity rhythm was perversed within the first hours after injection and improved on subsequent observation. Moreover the earlier death was marked in these animals.
