Adenohypophysis and growth in tadpoles of Rana temporaria

General and Comparative Endocrinology, 1978
Growth of the Rana temporaria tadpole was investigated after (1) adenohypophysectomy, (2) autografting the adenohypophysis to the tail, and (3) homografting an extra adenohypophysis into the tail of the otherwise normal tadpole. All operations were performed using the early tail-bud embryo.

Tooth replacement in the frog Rana temporaria

Journal of Morphology, 1966
AbstractThe development and replacement of teeth in the frog Rana temporaria is analyzed by dividing the life cycle of the tooth into a number of stages. These stages are identified by the examination of alizarin whole mounts. The dentition in this species is fairly complete and the percentage of functional loci is approximately 74.

Action of Insulin on the Frog (Rana temporaria)

Nature, 1953
EARLIER investigations of the action of insulin on cold-blooded vertebrates have shown that, although large doses usually lead to the appearance of typical convulsions, there is often a long latent period (1–2 days at room temperature) during which there are no visible symptoms1–3. In experiments performed in March and May 1952 the action of insulin on

DNA synthesis during the development of Rana temporaria

Experimental Cell Research, 1966
Abstract For the first time a curve is published exhibiting all the four phases of DNA synthesis obtained during amphibian embryogenesis, and including so many determinations that each point, and therefore the phases, are established with satisfactory statistical significance.

Caryotypes de Rana temporaria (L.) et de Rana dalmatina (Bonaparte)

Chromosoma, 1967
The karyotype of Rana temporaria is analysed from preparations of squashed tadpole epidermis, the karyotype of Rana dalmatina from preparations of squashed larval epidermis and adult tissues. For each of these two species, the 26 chromosomes of the karyotype have been divided in two groups according to their length.

Lipidkugeln im Plexusepithel von Rana temporaria L.

Zeitschrift f�r Zellforschung und Mikroskopische Anatomie, 1970
Das Plexusepithel von Rana temporaria L. enthalt zwei verschiedene Typen von Lipidkugeln, die einen Durchmesser bis zu 8 μ erreichen konnen. Diese Einschlusse haben keine Zytomembran. Die Struktur der Einschluskorper wird mit Hinweisen auf die Fixierung und den Stoffwechsel diskutiert.
