| a volatile, heat-stable anesthetic is not present in the skin of bufo asper (gravenhorst). | a study was made concerning the possible existance of a volatile, heat-stable anesthetic popularly believed by the thai people to be in the skin of bufo asper. the skin together with the paratoid glands of two toads were dried and pyrolyzed. mice and rats inhaling a continuous stream of the smoke or injected with a high dose of the volatile material showed signs of extreme irritation with no loss of consciousness. it is concluded that the skin of this toad does not contain a volatile, heat-stabl ... | 1988 | 3363570 |
| the diversity and evolution of locomotor muscle properties in anurans. | anuran jumping is a model system for linking muscle physiology to organismal performance. however, anuran species display substantial diversity in their locomotion, with some species performing powerful leaps from riverbanks or tree branches, while other species move predominantly via swimming, short hops or even diagonal-sequence gaits. furthermore, many anurans with similar locomotion and morphology are actually convergent (e.g. multiple independent evolutions of 'tree frogs'), while closely r ... | 2016 | 27707867 |
