Identification of biologically active fractions in the dermal secretions of the genus Bombina (Amphibia: Anura: Bombinatoridae)
Amphibian skin secretions have long been considered a convenient and useful natural source of bioactive compounds, but a comprehensive study of the effects of their dermal secretions on diverse parameters of the hemostasis system has not yet been carried out. This study aimed at identifying biologic...

Amphibian skin secretions have long been considered a convenient and useful natural source of bioactive compounds, but a comprehensive study of the effects of their dermal secretions on diverse parameters of the hemostasis system has not yet been carried out.

For the skin secretion analysis, we performed ion-exchange chromatography, electrophoresis, and zymography assays. Plasma coagulation tests, chromogenic assays, and platelet aggregation assays were also conducted in vitro.
