Neutralização da toxina tetânica pela clorofila hidrossolúvel

Revista da Faculdade de Medicina Veterinária, Universidade de São Paulo, 1950
Confirming the studies of F onseca R ibeiro and Guimaraes, the authors showed besides that with a contact for 15 minutes, 0.5 ml. of hydro-soluble chlorophyll at 1% neutralizes 500 M.L.D. of tetanic toxine; that 100 ml. of tetanic toxine (concentration of 1 ml. = 15,000 M.L.D. guinea pigs) in contact with 1,0 g.

Hurricane‐induced changes in mayfly assemblage structure, production and emergence in a tropical island stream Cambios inducidos por los huracanes en la estructura, producción, y emergencia del ensamblaje de Ephemeroptera de una quebrada de isla tropical

Ecological Entomology, Volume 50, Issue 1, Page 201-213, February 2025.
Hurricanes create major disturbances to stream ecosystems by producing large floods and removing riparian vegetation. Understanding their impacts is a priority, as hurricane intensity will increase with global climate change. Hurricane disturbance shifts mayfly assemblages from dominance by Leptophlebiidae before to Baetidae after.
