DHHS human subjects protection: the new regulations revisited

In January of 1981 DHHS released its revised regulations for the protection of human subjects. These new regulations established five categories of federally funded research--primarily in the educational, social and behavioral sciences--which, at local Institutional Review Board (IRB) US ISSN (0193-7758) 1168 option, could be made exempt from mandated peer review. A survey of the 562 member IRB system was conducted to determine, among other things, what policies individual review boards had established with regard to these optionally exempted categories. 341 (61%) of the IRBs responded to the survey. Results indicate that the IRBs have overwhelmingly opted to maintain review procedures at some level in each of the "exempted" categories and that these procedures, as well as the other DHHS standards, are being applied almost universally to all research regardless of funding source. This article presents data on IRBs and their implications for the educational, social and behavioral sciences.     

Application of forensic toxicology to the problem of domestic violence.

The role of the forensic toxicologist in helping to determine causes of death or in aiding in the resolution of "driving under the influence" or similar cases is well known and clearly understood. Less clearly defined is the position of the forensic toxicologist vis-à-vis other socially significant problems. However, as the 21st century approaches, it is worth considering how forensic toxicology can help in unraveling some of these problems. The problem of violence between intimates--that is, domestic violence--is a social problem in which it has been long felt that alcohol has played a part. Until now, though, no carefully controlled toxicological studies have been conducted to substantiate this or to determine whether other drug use is associated with domestic violence. At the San Francisco Medical Examiner's Office, toxicological data from both the victim and the suspect in 20 cases of domestic violence that ended in homicide have been gathered. It was found that alcohol or other drugs or a combination of these factors was invariably present in the suspect, the victim, or both. The implications of these results and how they can be used to develop a toxicological strategy to help reduce the most serious consequences of domestic violence are presented.     

Genetic markers in human bone: I. Deoxyribonucleic acid (DNA) analysis.

Deoxyribonucleic acid (DNA) was isolated from a number of spongy and compact human bone tissue specimens, and the yield was estimated on a "per milligram of starting tissue" basis. DNA was, in addition, isolated from a number of corresponding blood and bone tissue specimens. Spectrophotofluorometry and ethidium bromide visualization on minigels were used to estimate the quantity and degree of degradation of DNA. The DNA from several blood-bone pairs is shown to give concordant restriction fragment length polymorphism (RFLP) typing results by two different typing protocols with five different single-locus probes. DNA from several additional blood-bone pairs is shown to give concordant results for human leucocyte antigen (HLA)-DQ alpha phenotypes following polymerase chain reaction (PCR) amplification and hybridization to specific allele-specific oligonucleotide (ASO) probes, and for the variable numbers of tandem repeats (VNTR) length polymorphisms 3' to the human apolipoprotein B (APOB) gene following PCR amplification with specific primers and analysis of the products by electrophoresis and ethidium bromide visualization.
