ABSTRACT
With the aim to determine if the tremorgenic toxin of Ipomoea asarifolia is eliminated in milk, three groups of Swiss female mice received, immediately after giving birth until weaning, a ration containing 20% or 30% of dry I. asarifolia. All the offspring of the females that received 20% or 30% I. asarifolia showed tremors 2-4 days after birth. The offspring of the females that received 20% I. asarifolia recovered 4-7 days after weaning. The offspring of the females that received 30% of the plant in the ration died while showing tremors before weaning or up to two days after weaning. It is concluded that the tremorgenic compound of I. asarifolia or its toxic metabolites are eliminated in milk, and that lactating mice may be used as a model for the determination of the toxic compound(s) in this plant.(AU)
RESUMO
Com o objetivo de determinar se a toxina tremorgênica da Ipomoea asarifolia é eliminada pelo leite, três grupos de camundongos fêmeas da linhagem Swiss receberam, imediatamente após o parto até o desmame, ração contendo 20% ou 30% de folhas secas de I. asarifolia. Todos os filhotes das fêmeas que receberam 20% ou 30% de I. asarifolia apresentaram tremores 2-4 dias após o nascimento. Os filhotes das fêmeas que receberam 20% de I. asarifolia se recuperam 4-7 dias após o desmame. Os filhotes das fêmeas que receberam 30% da planta na ração morreram antes do desmame ou até dois dias após o desmame, ainda apresentando tremores. Conclui-se que o componente tremorgênico de I. asarifolia ou seus metabólitos são eliminados no leite, e que camundongos fêmeas em lactação podem ser usados como um modelo para a determinação do(s) composto(s) tóxico(s) desta planta.(AU)
