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.  相似文献

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.  相似文献

Narcotics "body packing" can be detected in abdominal X-rays by the ring shadow caused by air trapped in the packs. In a series of 82 cases admitted for abdominal X-ray in Helsinki, Finland, in 1982 through 1988, we encountered 9 (11.0%) true positives, 3 (3.6%) false positives, and 1 (1.2%) false negative. The false positives were due to the constipation often associated with the narcotics abuse. The false negative X-ray diagnosis was attributable to an inexperienced radiologist. False negatives may also be associated with packets containing marijuana, packs with few wrappings, aluminum-foil coated packs, and machine-packed narcotics. Searching for trapped air in radiographs, repeated X-raying by an experienced radiologist, use of computed tomography, or combined urinary drug screening may be applied to diminish false findings and to avoid unnecessary arrest for the purpose of fecal screening over several days.  相似文献
