Correlation between plasma and bone marrow tricyclic antidepressants has not been studied before. Two groups of rabbits were given 10 and 20 mg of desipramine/kg body weight, respectively. Desipramine was administered to the animals once daily by mouth for 5 days. On the fifth day the animals were sacrificed and blood and bone marrow samples were collected and analyzed using a high performance liquid chromatographic (HPLC) method. Data showed that a correlation exists between bone marrow and blood desipramine. The bone marrow desipramine concentration increased as its blood levels increased. The average ratio of bone marrow to blood desipramine +/- S.D. (standard deviation) in both dosage groups was 37.2 +/- 4.46 with a range of 30.99-44.82. This investigation is promising and shows that bone marrow could be used as an alternative tissue in the absence of a suitable blood sample.  相似文献

This article examines voluntary mediation and provides suggested criteria for attorneys in deciding whether or not to use mediation.

In motorcycle accidents involving two riders, medicolegal identification of the driver is necessary when one or both riders die. It is particularly important in the latter case, because the survivor almost always insists that he or she was not driving. One characteristic injury that distinguishes the driver from the passenger is inguinal contusion-laceration (accompanied internally by pelvic fracture). This injury, caused by collision of the pelvis with the fuel tank, identifies the driver.  相似文献

Kindergarten policy varies widely both across and within states. Over the past decade, a number of states have instituted a full‐day kindergarten requirement and others are considering it as a way to increase educational achievement. Many parents also support full‐day kindergarten as a source of child care. This paper uses the Early Child Longitudinal Study–Kindergarten Class of 1998–1999 to evaluate the efficacy of this policy. In ordinary least squares, probit, county fixed effects, and instrumental variables models, we find that there are initial benefits for students and the mothers of students who attend full‐day kindergarten, but that these differences largely evaporate by third grade. Contrary to claims by some advocates, attending full‐day kindergarten is found to have no additional benefit for students in families with income below the poverty threshold. © 2006 by the Association for Public Policy Analysis and Management  相似文献

This study probes the interconnections among distrust of government, the historical context, and public support for the death penalty in the United States with survey data for area-identified samples of white and black respondents. Multilevel statistical analyses indicate contrary effects of government distrust on support for the death penalty for blacks and whites, fostering death penalty support among whites and diminishing it among blacks. In addition, we find that the presence of a "vigilante tradition," as indicated by a history of lynching, promotes death penalty support among whites but not blacks. Finally, contrary to Zimring's argument in The Contradictions of Capital Punishment , we find no evidence that vigilantism moderates the influence of government distrust on support for the death penalty, for either whites or blacks. Our analyses highlight the continuing influence of historical context as well as contemporary conditions in the formation of public attitudes toward criminal punishment, and they underscore the importance of attending to racial differences in the analysis of punitive attitudes.  相似文献
