Abstract :In order to investigate whether or not heparin produces any effect on the tail regeneration in Triturus ensicaudu, a kind of newt, this study was attempted. After amputating the tails of the newt at a point, one third from the end, ten of these animals were put in a glass vessel and raised together at room temperature. The growth of the tail tips was then measured. 1. Normal regeneration in Triturus ensicauda. Four months after amputalion regeneration of the tails was still incomplete, and during this period the growth reached almost the half length of the preamputated condition. Difference of the length of regenerated tails between the adult female and male is not so considerable. Altboulh the regenerated part of the tail in young male is longer than that of the adult one. 2. Effect of heparin injected. Heparin used for this investigation was heparin sodium (l000 heparin units/ml) manufatured by Takeda Chemical Co. Ltd. Several different dilute solutions of heparin sodium injections, such as 50, 25, 12. 5, 0.25 0.025, 0.0025, and 0.00025 heparin unilts/ml, were injected once a day during the experiment. The result of the observations shows that injections of 50 to 0.025 heparin units/ml depress the growth of tail tips. On the other hand, 0.0025 to 0.00025 heparin units /ml did not seem to depress the regernoration in the tails.
