A rapid and efficient procedure is described for the extraction and analysis of oxazepam, the major urinary metabolite of diazepam in greyhounds. Urine was extracted by passing through a bonded silica column (Bond Elut) following enzyme hydrolysis. The adsorbed drug was eluted and then detected and measured by high performance liquid chromatography (HPLC). Recoveries were in excess of 85% at 50 ng/ml concentrations. Detection was possible up to 30 h after a single oral dose of diazepam (5 mg). 相似文献

The 1H nuclear magnetic resonance (NMR) chemical shifts and coupling constants of heroin's D ring H-15 alpha, H-15 beta, and H-16 alpha, and H-16 beta are presented. These assignments were accessible through the introduction of a double bond (delta 15,16) in heroin. The resulting compound, delta 15,16 didehydroheroin, was subjected to deuterium exchange or stereoselective reduction or both. Reduced products d1-16 alpha heroin d2-15 alpha, 15 beta-heroin, and d3-15 alpha, 15 beta, 16 alpha-heroin are presented. Heroin with deuterated acetyls is also presented for 1H NMR spectral clarity in the D ring area. 相似文献

Abstract This is an evaluative study of a juvenile probationary project in which youth are ordered to pay restitution as a term of probation and, to assure them means of compliance, the juvenile court arranges for and supplies their employment. Demographic variables (age and sex) and court-related variables (plea, length of probation, amount of restitution ordered, and amount and proportion actually paid) are examined in relation to one another and, most important, in relation to recidivism as measured by subsequent law violations for which the offender was investigated, and subsequent law violations that resulted in formal charges against the youth. The data demonstrate that recidivism is related to severity of the initial offense, but more important, it is related to the youth's success in achieving the restitution goal. Successful compliance with the restitution order, when success is measured by amount of restitution paid relative to the amount ordered by the court, is significantly related to revocation of probation, time given to pay, amount ordered to be paid, and subsequent offenses charged. Indeed, the proportion of restitution paid is the most important predictor of recidivism. The data reinforce the dominant legislative position that an offender's ability to pay must be taken into account in ordering restitution. 相似文献
