    摘要: A process for determining the concentration of benzodiazepines in a body liquid comprising the steps of contacting freeze-dried brain tissue with tritium labelled flunitrazepam to bond labelled flunitrazepam to receptor sites of the brain tissue, determining the concentration of labelled flunitrazepam of the brain tissue, incubating the brain tissue containing labelled flunitrazepam with a sample of body liquid containing benzodiazepine, the concentration of which is to be determined, to induce displacement of labelled flunitrazepam from said brain tissue, determining the concentration of labelled flunitrazepam bonded to the brain tissue after establishing equilibrium conditions and determining the concentration of benzodiazepine in the body liquid based on the change of concentration of labelled flunitrazepam induced by benzodiazepine contained in the sample.
