A method is described for the determination of delta 9-tetrahydrocannabinol (delta 9-THC) in the saliva by the use of a combination of moving-precolumn injector and glass capillary gas chromatograph with electron capture detector (GC/ECD). There were no interfering peaks due to impurities around the peak of pentafluoropropyl derivative of delta 9-THC (delta(More)
PURPOSE Three products can be used in Japan for the reconstitution of cytotoxic agents: PhaSeal, Chemo CLAVE and Chemo Mini Spike (CMS). The low preparation volume may be affected by residual-related volume in their devices. In this study, the residual-related error in their devices was examined and compared. METHOD The blank of each component of these(More)
PURPOSE Cyclophosphamide (CP) contamination has been detected in Japanese hospitals. In other countries, the surface contamination of CP vials has been reported; however, the manufacturing process of Japanese CP vials is unknown, so the conditions are not necessarily the same as in other countries. This study aimed to establish whether vial surface(More)
1-Methyl-1,2,3,4-tetrahydro-beta-carboline (1-MeTHBC) and 6-methoxy-1-methyl-1,2,3,4-tetrahydro-beta-carboline (6-M-1-MeTHBC) were identified and quantified in the urine of 131 healthy volunteers by gas chromatography/mass spectrometry (GC/MS) with a chemically-bonded glass-capillary column. 1-MeTHBC was present naturally in the human urine, whereas(More)
The cause for discrepancies in results from different methods of the carboxyhemoglobin (HbCO) analysis on the blood from bodies of burn victims was investigated. Blood samples with 0, 50, and 100% carbon monoxide (CO) saturation were heated at various temperatures for some time and then analyzed. Carboxyhemoglobin content was determined by the(More)
