A preliminary study on the distribution of morphine and its glucuronides in the subcompartments of blood.
[Abstract ] The distribution of morphine, morphine-3-glucuronide (M3G), and morphine-6-glucuronide (M6G) in whole blood, plasma, and packed erythrocytes was studied. Parameters investigated were the hematocrit values (10, 42, 44, and 71%) and the water content of the samples. The blood-to-plasma ratio of morphine concentrations was unaffected by variations in hematocrit and water content, whereas the corresponding ratios for M3G and M6G were strongly influenced. Ratios were 0.53 to 0.65 and 0.52 to 0.62 in specimens with average hematocrit values (42 and 44%, respectively), and the ratios were 0.81 or 0.89 (hematocrit 10%) and 0.27 or 0.28 (hemalocrit 71%) in blood samples with different he…
Experimental Investigations on Hair Fibers as Diffusion Bridges and Opiates as Solutes in Solution
Diffusion experiments were performed using clipped hair fibers as diffusion bridges and aqueous solutions of morphine, codeine and dihydrocodeine. Natural as well as predamaged hair fibers were investigated. The test series were conducted at ambient temperature and at high humidity. After 312 or 372 hours the middle segments of the strands were clipped, washed and analyzed by GC/MS. Only when virgin hair samples were used the solutes passed along the fiber at full length resulting in a positive immunological finding at the end of the diffusion bridge. Most of the washing fluids were positive for opiates. All centerpieces had a high opiate content. The opiate concentration in damaged hair wa…
