Estudos toxinológicos do ouriço-do-mar Echinometra lucunter / Toxinologic studies about Echinometra lucunter sea urchin

RESUMO

Echinometra lucunter (Linnaeus, 1758) e o ourico do mar mais conhecido da costa brasileira, responsavel por cerca de 50% dos acidentes com animais marinhos. A injuria inicial causada pelos ouricos e a penetracao dos espinhos na pele, seguida da retencao de seus fragmentos. Esses fragmentos causam reacoes inflamatorias, dor local, e ocasionalmente doenca sistemica,sintomas que eram atribuidos somente ao trauma mecanico. Acidentes apos a ingestao de ovas tambem ja foram descritos. O objetivo deste trabalho foi verificar a presenca de toxinas nos espinhos e no liquido celomico perivisceral do ourico do mar E. lucunter do litoral de São Paulo, isolar e caracterizar essas moleculas e avaliar a correlacao histologica entre as toxinas presentes e uma possivel estrutura sectora... .

ABSTRACT

Echinometra lucunter (Linnaeus, 1758) is the most spread the sea urchin of the Brazilian shore line and its responsible for circa 50% of all marine animals acidents. Initial sea urchin injury is caused by the spine penetration, followed by its fragmentation under the skin. This fragments can cause local pain and inflammatory reactions, initially atributed to the mechanical trauma of the spines penetration, and ocasionally systemic disorders. Few accidents were reported after the ingestion of raw sea urchin. The aim of this work was to asses the presence of toxins in the spines and perivisceral celomic fluid of E. lucunter sea urchun from São Paulo shore line, through the biological driven isolation and biochemical characterization of the toxins... .
