The proteins from the venom of the scorpion Hadruroides lunatus were separated by ionexchange chromatography on CM-Sephadex C-25 with 0,05M ammonium acetate buffer pH 7, getting six protein peaks in the process. The toxicity tests allowed the identification of three toxins that were denominated Hl1, Hl2 y Hl3; which immobilize, respectively, insects (Grillus sp.), crustaceans (Porcellio laevis) and the inoculated limb of white mice. The three toxins are basic proteins and have no proteolitic or phospholipase activity. In addition, Hl3 increases the plasmatic level of creatine kinase after its inoculation in the gastrocnemius muscle of mice. By PAGE-SDS, Hl3 shows only one protein band of 12,5 KDa, while the other toxins have protein contaminants.

We present an updated list of amphibians occurring in Peru, and for Andean amphibians (those which are found above 1000 m of altitude) IUCN categories, number of endemic species, threats and presence in SINANPE (National System of Protected Areas of Peru) are mentioned. 538 species of amphibian are recognized in Peru at 2010, 110 species were registered since 2003 to 2010, one species per month. Of those 110 species, 77 were Andean species and 64% of them occur outside SINANPE. A total of 235 Andean species are recognized, 80% are endemic to Peru and 58% of these endemic species are outside SINANPE. A total of 91 Andean species are in threatened and Near Threatened categories, and 53% of them occur outside SINANPE. Genera Telmatobius and Atelopus, as well as, families Centrolenidae and Strabomantidae occurring in Peru, show the highest percentage of Andean species categorized as threaten...

Presentamos una lista actualizada de los anfibios presentes en Perú y para las especies andinas (con distribución altitudinal sobre los 1000 m de altitud) se informa sobre su categoría según la UICN, los endémicos de Perú, sus amenazas y su presencia dentro del SINANPE. Hasta el año 2010 se conocen 538 especies de anfibios; 110 especies fueron registradas entre el año 2003 y el 2010; aproximadamente una especie descrita por mes. De las 110 especies descritas desde el 2003, 77 fueron andinas y 64% de éstas se encuentran fuera del SINANPE. En total son reconocidas 235 especies andinas, el 80% son endémicas de Perú y 58% de éstas se encuentran fuera del SINANPE. Noventaiun especies andinas están en categorías de amenaza y en la categoría de Casi Amenazado, y 53% de éstas se encuentran fuera del SINANPE. Los géneros Telmatobius y Atelopus, así como las familias Centrolenida...
