| The primary clinical symptom of Paralytic Shellfish Poisoning is acute paralytic illness produced by paralyzing toxins. Paralytic shellfish poison is formed by a mixture of phycotoxins and their toxicity is due to its reversible binding to a receptor site on the voltage-gated sodium channel on excitable cells, thus blocking neuronal transmission. We studied the effect of the gonyautoxin 2/3 epimers by local infiltration in the anal internal sphincter of healthy voluntary adults in order to reduce anal tone. The toxin was injected after prior clinical evaluation, anoscopy and anorectal manometry. Post injection clinical examination, electromyography and anorectal manometry were performed. Resting and voluntary contraction pressures were measured and the... |

| Los estudios relacionados con la composición dietaria de los anuros presentes en Chile son un campo escasamente explorado y que permiten aportar con conocimiento sobre la biología de las especies. Alsodes coppingeri habita los arroyos de montaña de los bosques templados de Nothofagus de la Patagonia chilena. Estos anuros han sido encontrados bajo troncos en los márgenes de arroyos. Para este estudio se analizaron 44 especímenes de A. coppingeri provenientes de Laguna Caiquenes, Caleta Tortel y Villa O’Higgins (Región de Aysén, Chile). Los ítems presa fueron clasificados a nivel ordinal y se estimó la frecuencia de ocurrencia, de abundancia e índice de importancia relativa (IRI). Se determinó un 70,5% de frecuencia de ocurrencia, donde la dieta de... |
