Rhodanese (thiosulfate:cyanide sulfurtransferase) from frog Rana temporaria
Journal of Chromatography B: Biomedical Sciences and Applications, 2000The molecular mass of rhodanese from the mitochondrial fraction of frog Rana temporaria liver, equaling 8.7 kDa, was determined by high-performance size exclusion chromatography (HP-SEC). The considerable difference in molecular weight and the lack of common antigenic determinants between frog liver rhodanese and bovine rhodanese suggest the occurrence

Retinoscopic and neurophysiological refractometry in rana temporaria
Pfl�gers Archiv European Journal of Physiology, 1972If frogs are measured by objective refractometry one finds a hyperopia of 6 D to 9 D. Therefore we investigated the neurophysiological state of refraction of the immobilized rana temporaria using the technique of extracellular recording. In the superficial neuropil the neural activity of 32 recorded neurons showed no dependence on the state of ...

Journal of Genetics, 1949
White frog spawn gave rise to black-eyed white tadpoles, which later darkened, and developed into normal frogs. The latter produced normal tadpoles, some of which developed into albino adults. The facts can be explained if albinism is recessive, but the dominant allelomorphic gene found in normal frogs produces enough pigment in the eggs of ...

The Common Frog Rana temporaria
1991The oocytes, embryos, and larvae of Rana temporaria have long been traditional subjects of diverse experimental embryological studies. Experimental embryologists have often used the embryos of R. temporaria for studies concerning the mechanisms of development. In the first half of this century experiments were carried out on eggs collected from natural

MHC zygosity in the frog, Rana temporaria
Immunogenetics, 1984The major histocompatibility complex (MHC) zygosity of the field-collected frogs, Rana temporaria, was detected by progeny testing. Groups of sibling tadpoles were grafted with intrafamilial tail-tip allografts and the ratio of rapidly rejected allografts to slowly rejected ones was estimated.

Behavioural adaptations of Rana temporaria to cold climates
Journal of Thermal Biology, 2015Environmental conditions at the edge of a species' ecological optimum can exert great ecological or evolutionary pressure at local populations. For ectotherms like amphibians temperature is one of the most important abiotic factors of their environment as it influences directly their metabolism and sets limits to their distribution.

Isolation of Neurohypophysial Hormones of Rana temporaria
Nature New Biology, 1972THE neurohypophysial hormones of several vertebrates have been identified1–3, but the nature of the neurohypophysial principles of amphibians is in doubt. Vasotocin (8 Arg-oxytocin) is known to be present, but the oxytocic component could be either oxytocin, mesotocin (8 Ileu-oxytocin) or both1–7. Since the neutral peptides are difficult to distinguish

NAG infection in tadpoles of Rana temporaria
Bulletin of Experimental Biology and Medicine, 1976In a series of experiments 2250 tadpoles were infected with three strains of NAG vibrios. It can be concluded from the results of bacteriological and pathomorphological electron-microscopic and light-optical investigations that during the first 2 days the animals develop and recover from an acute infection, but the vibrios later persist for a long time
