A method is described whereby lignocaine can be measured in small samples of canine myocardium. A proteolytic enzyme is used to digest the tissue, and the drug, together with an internal standard, is subsequently extracted into an organic solvent and measured by gas-liquid chromatography. The method is reproducible using tissue samples as small as 50 mg and appears to be suitable for the measurement of a number of drugs in small samples of tissue.
本文描述了一种可在犬心肌小样本中测量利多卡因的方法。使用一种蛋白水解酶消化组织,随后将药物与内标物一起萃取到有机溶剂中,并通过气液色谱法进行测量。该方法使用低至50毫克的组织样本即可重现,似乎适用于测量小组织样本中的多种药物。
