A sensitive analytical method was developed for quantitative analysis of delta(9)-tetrahydrocannabinol (delta(9)-THC), 11-nor-delta(9)-tetrahydrocannabinol-carboxylic acid (delta(9)-THC-COOH), cannabinol (CBN) and cannabidiol (CBD) in human hair. The identification of delta(9)-THC-COOH in hair would document Cannabis use more effectively than the detection of parent drug (delta(9)-THC) which might have come from environmental exposure. Ketamine was added to hair samples as internal standard for CBN and CBD. Ketoprofen was added to hair samples as internal standard for the other compounds. Samples were hydrolyzed with beta-glucuronidase/arylsulfatase for 2h at 40 degrees C. After cooling, samples were extracted with a liquid-liquid extraction procedure (with chloroform/isopropyl alcohol, after alkalinization, and n-hexane/ethyl acetate, after acidification), which was developed in our laboratory. The extracts were analysed before and after derivatization with pentafluoropropionic anhydride (PFPA) and pentafluoropropanol (PFPOH) using a Hewlett Packard gas chromatographer/mass spectrometer detector, in electron impact mode (GC/MS-EI). Derivatized delta(9)-THC-COOH was also analysed using a Hewlett Packard gas chromatographer/mass spectrometer detector, in negative ion chemical ionization mode (GC/MS-NCI) using methane as the reagent gas. Responses were linear ranging from 0.10 to 5.00 ng/mg hair for delta(9)-THC and CBN, 0.10-10.00 ng/mg hair for CBD, 0.01-5.00 ng/mg for delta(9)-THC-COOH (r(2)>0.99). The intra-assay precisions ranged from <0.01 to 12.40%. Extraction recoveries ranged from 80.9 to 104.0% for delta(9)-THC, 85.9-100.0% for delta(9)-THC-COOH, 76.7-95.8% for CBN and 71.0-94.0% for CBD. The analytical method was applied to 87 human hair samples, obtained from individuals who testified in court of having committed drug related crimes. Quantification of delta(9)-THC-COOH using GC/MS-NCI was found to be more convenient than GC/MS-EI. The latter may give rise to false negatives due to the detection limit.  相似文献

Using data from an experimental evaluation of the New Hope project, an anti‐poverty program that increased employment and income, this study examined the effects of New Hope on entry into marriage among never‐married mothers. Among never‐married mothers, New Hope significantly increased rates of marriage. Five years after random assignment, 21 percent of women assigned to the New Hope condition were married, compared to 12 percent of those assigned to the control group. The New Hope impact on marriage was robust to variations in model specification. The program also increased income, wage growth, and goal efficacy among never‐married mothers, and decreased depression. In non‐experimental analyses, income and earnings were associated with higher probability of marriage and material hardship was associated with lower probability of marriage. © 2006 by the Association for Public Policy Analysis and Management  相似文献

In this work, we established a procedure for evaluation of the efficiency of the water supply. This procedure has allowed us to find that the proposed indicators have a discriminating capability in the analysis of the service, and to reject criticisms traditionally assigned to the sensitivity of the data envelopment analysis (DEA) technique in relation to degrees of freedom. The results obtained show that the population density, as a factor that defines one of the particular characteristics of the surroundings of each municipality, has a statistically significant impact on the indexes of efficiency, this affirmation not being extended to the public or private ownership of the service. The scale inefficiency is higher than the technical inefficiency. These typologies of efficiency are, principally, motivated by the supply side of the service, which is specially linked with the necessary infrastructure. The demand of the citizens is satisfied with a behavior close to optimal.  相似文献
