title: [Chemomorphological data (glycogen, G-6-P-DH, RNA) in the regeneration blastema ofLineus sanguineus rathke (Nemertini)].
abstract: The head regeneration ofLineus sanguineus consists of two periods. During the phase ofproliferation the wounds are covered with epidermis, thereafter immigrating blastocytes build up the blastema. During the phase ofdifferentiation anlagen are discernible, which subsequently become the head organs. Proliferation of epidermis, the building of blastema and the differentiation of the organs (cerebral organs, foregut and proboscis) are histochemically characterized in the same way: in the beginning there is a high glycogen content in the morphogenetic areas, which decreases during further development with increasing G-6-P-DH activity and with growing RNA concentration. These results indicate that in morphogenetic areas the glucose resulting from glycogenolysis is metabolized by the pentose-phosphate-shunt and is utilized for the synthesis of nucleic acids.
