Identification of flurazepam (Dalmane) and a primary metabolite in urine by thin-layer chromatography.

A relatively simple, routine method has been described for the qualitative identification of flurazepam and its primary metabolite 7-chloro-1-(2-hydroxyethyl)-5-(2-fluorophenyl)-1,3-dihydro-2H-1,4-benzodiazepin-2-one in urine. We have described two extractions and several identification procedures by which flurazepam and its primary urinary metabolite can be identified by TLC.     

HOMICIDE TRENDS IN ATLANTA

In recent years in Atlanta, homicide has been the most common cause of death in males 20–40 years of age. To study homicide trends in this city we analyzed data for 591 resident victims of criminal homicide in two time perid. 1961–1962 and 1971–1972. Large increases occurred in the homicide rates for both black and white residents. In both races, these rate increases could be accounted for almost entirely by homicides involving firearms Homicide rates for black and whites in 1971–1972 were highest in census tracts with low indices of socioeconomic status; this association was found only for homicides in which the victim and assailant were relatives or acquaintances. There was little geographic overlap between areas with high rates of homicide in the home and high numbers of homicides in public. Using population-based rates facilitates comparisons of homicide occurrence between time periods and/or places.     

The Unauthorized Practice of law: Do Good Fences Really Make Good Neighbors—or Even Good Sense?1

While the legal profession's efforts to suppress the practice of law by non-lawyers go back to colonial times, the modern unauthorized practice movement began in the late 1800s and early 1900s. Its greatest success, however, took place during the 40 years from 1920 to 1960. Recent years have seen the reversal of some of the prior successes in the field, and current challenges to unauthorized practice restrictions raise serious questions about their present validity. Do the benefits to the public from the enforcement of rules against the unauthorized practice of law justify continuation of the effort?
