title: [Analysis of substances issuing from Zajdela ascitic hepatoma cells after exposure to UV radiation of different wave-lengths. I. Relationship to dose].
abstract: The release of substances from the Zaidela ascitic hepatoma cells after irradiation with physiological doses of short-wave (254 nm) and long-wave (300-380 nm) UV light (far and near UV light) has been studied spectrophotometrically. Within the range of 200-520 nm, the absorption spectra of releasing substances show maxima at 215 and 260 nm and are identical to spectra of non-irradiated cells. The amount of substances increases with dose making up, at the maximal alteration, 180-220%, of the amount releasing from non-irradiated cells. Irradiation with far UV light exceeds by one order that with near UV light. The effect of minimum doses is opposite to the action of high doses: the release of substances from irradiated cells is much less.
