In 1901, Vital Brazil, working at the Instituto Butantan in São Paulo, Brazil, developed the first monovalent and polyvalent antivenoms for Central and South American Crotalus and Bothrops genera,[21] as well as for certain species of venomous spiders, scorpions, and frogs. It does not appear that humans could be naturally immune to animal venom, but some individuals may be more or less susceptible to its effects. [15] In addition, opossums are being studied for antivenom production. 202 The dRVVT uses Russell viper venom in a system containing limiting quantities of diluted rabbit brain phospholipid. Early specific antivenom treatment, 3–6 hours after systemic envenoming, restored the coagulation function in 1–2 days and seemed to be statistically effective in reducing the severity of renal damage compared with the historical and delayed group by the Wilcoxon rank-sum test. • Hawgood BJ (November 1994).
