✦ Synopsis


The concentrations of methadone in human hair were measured. The washed hair was cut in l-ram pieces approximately, then incubated overnight at 45Β°C with 0. ] m HC1. The extracts were alcalized by 1 m NaOH and diluted by phosphate buffer, pH 7.4. The methadone concentrations were determined by radioimmunoassay. The method is simple, rapid, and practicable for routine determination. Key word: Methadone, radioimmunologic determination in hair Zusammenfassung. Die Konzentration von Methadon im menschlichen Haar wurde bestimmt. Die gewaschenen Haarproben wurden in ca. 1 mm lange Stficke geschnitten und mit 0.1 m HC1 tiber Nacht bei 45Β°C inkubiert. Die Extrakte wurden mit 1 m NaOH alkalisiert und mit Phosphat-Puffer pH 7.4 verdtinnt. Die Methadonkonzentrationen wurden mittels Radioimmunoassay gemessen. Diese Methode stellt eine einfache und schnelle Routinebestimmung dar.

A simple procedure for the determination of cocaine in human hair was described. After washing hair samples were crushed in 0.1 m HC1 and incubated overnight at 45Β°C. The acid extracts were neutralized with 1 m NaOH. Phosphate buffer (pH 7.4) was added to the extracts. The cocaine concentrations wer
