AIM The phenomena of hypergravity and microwave radiation are widespread, which cause more and more concern for the hazards to human health. The aim of this study was to investigate the synergistic effect of microwave radiation and hypergravity on rats and observe the protective effect of Rana sylvatica Le conte oil. METHODS Rats were exposed to microwave radiation and hypergravity, and the r...

SOME ASPECTS OP PTERIDINE BIOSYNTHESIS IN AMPHIBIANS by Hamilton Lee Stackhouse Bright fluorescing unconjugated pteridines have been extracted from amphibians; yet the biological function of these compounds in vertebrates is not completely understood. There is some evidence, indicating that they can act as pigments, co-factors, and growthpromoting substances. Pteridine biosynthesis is unknown b...

Deformed amphibians have been observed in the Kenai National Wildlife Refuge, Alaska. Environmental variables such as contaminants, ultraviolet radiation [UV], or parasites may cause deformities. It is important to identify the environmental cause of deformities in order that effective management strategies can be implemented to enable the recovery of affected populations. To determine whether ...

Phylogenetic relationships among the species of true frogs (Rana) from North, South, and Central America were investigated based on the sequences of approximately 2 kb from the mitochondrial genome, sampled from most of the described species, as well as eight undescribed species. This analysis, combined with previous studies of the phylogeny of New World Rana, served as the basis for a revised ...
