Abstract:

Thirty-two New Zealand Albino rabbits (1.5-2.0 kg) were dosed on a daily basis with 20 mg/kg nortriptyline (NT) prior to feeding for a period of five days. On the fifth day of dosing, the animals were sacrificed approximately 1.5 h after the final dose. A comparison was made of nortriptyline concentrations in the blood and bone marrow at the time of sacrifice, and between bone marrow collected at the time of sacrifice and bone marrow collected at 2, 4, 6, 12, 24, 36, and 48 h after sacrifice. The results indicate that a linear relationship exists between blood and bone marrow NT concentrations, with an average marrow-to-blood ratio of 29.98 ± 3.91 and a correlation coefficient of 0.956. Additionally, there was no significant difference (p < 0.05) observed between NT concentrations in bone marrow at the time of sacrifice and its concentration up to 24 h after sacrifice. The results indicate that bone marrow may be used to predict blood concentrations of NT up to 24 h after death when a suitable blood sample is not available.

More about this publication?

• The Journal of Analytical Toxicology (JAT), established in 1977 and published 9 times a year, is the international source covering a broad range of clinical, forensic, and industrial laboratory topics regarding the isolation, identification, and quantitation of potentially toxic substances.

  With an emphasis on practical application, JAT articles provide improved and novel techniques for use in clinical, forensic, workplace, sports testing (doping), and other toxicology laboratories. Articles describe newly developed methods in immunoassay testing, gas chromatography, liquid chromatography, mass spectrometry, atomic absorption spectrometry, solid and liquid phase extraction techniques, and other analytical approaches. Worldwide readership includes toxicologists, pathologists, chemists, clinicians, researchers, and educators working in medical examiner and law enforcement laboratories, hospitals, university and independent analytical laboratories, as well as the drug manufacturing industry.

  Each year in October, we publish a special issue from the Society of Forensic Toxicologists.

  JAT, as determined by ISI Citation Index, is one of the two most referenced international journals in forensic science.
