[Cytochemical analysis of muscle cell histones of Triturus cristatus limbs a) in normal regeneration, b) in regeneration arrested by r-irradiation, and c) in regeneration restored by implants].
The muscular cells of regenerating limbs and of limbs in which regenerative power is restored, show an important decrease in the amount of cytophotometrically detected histones. This decrease is owing to the arginine rich fraction and to the lysine rich fraction. The muscular cells of irradiated limbs show a decrease in the amount of histones. This decrease is owing only to the arginine rich fraction and continues after the thirieth day of irradiation and amputation.
