- Executive summary:
Die Substanz Remazol-Goldgelb RNL (Charge Nr. CM 68344) lag als orangefarbenes Pulver vor. Zur akuten Behandlung wurde eine 25 %ige Suspension in E-Wasser (25 g/ad 100 mL) hergestellt und in der Dosierung von 5 000 mg/kg Körpergewicht einmalig mit der Schlundsonde weiblichen Wistar-Ratten (Stamm: Hoe WISKf(SPF71); Eigenzucht) im Gewicht von 175 bis 188 g (x = 181,1 g, s = 4,91 g, n = 10) verabreicht. Den Tieren wurde während 16 Stunden vor und 2 Stunden nach der Behandlung das Futter entzogen. Während der Nachbeobachtungszeit von 14 Tagen nach der Applikation erhielten die Tiere als Futter die Haltungsdiät ALTROMIN 1324 (Altromin GmbH, Lage/Lippe) und Leitungswasser ad libitum. Die Haltung der Tiere erfolgte in Gruppen in Kunststoffkäfigen auf Weichholzgranulat.
Nach Behandlung wurden die Vergiftungssymptome registriert. In der Nachbeobachtungszeit wurden die Tiere wöchentlich gewogen. Die überlebenden Versuchstiere wurden nach Ende der Nachbeobachtungszeit durch CO2-Gas getötet, seziert und makroskopisch untersucht.
Bei Verabreichung von 5000 mg/kg Körpergewicht starb kein Tier. Es wurden 2 Stunden p. a. Hyperreflexie sowie orange verfärbter Stuhl und Harn festgestellt. 48 Stunden nach der Applikation konnten keine Symptome mehr festgestellt werden.
Das Verhalten und die Körpergewichtsentwicklung war ab 48 Stunden post applicationem bis zum Versuchsende normal. Die Sektion nach Versuchsende ergab makroskopisch keine Besonderheiten.
Aufgrund der vorliegenden Versuchsanordnung war eine genaue Bestimmung der LD 50 nicht möglich. Die akute orale LD 50 für weibliche Ratten liegt jedoch mit Sicherheit über 5000 mg/kg Körpergewicht..
