A previous study suggested the usefulness of pericardial fluid (PCF) and bone marrow aspirate (BMA) for the postmortem analysis of ethanol. The present study reviewed forensic autopsy cases (n = 2,983), which included 683 cases with the following positive toxicological findings, to reassess ethanol distribution and to investigate other gaseous and volatile substances in blood, PCF and BMA. Toxicological analyses detected ethanol (>10 mg/dL, n = 345), acetone (>0.01 mg/dL, n = 402), cyanide (n = 282), toluene (n = 47), liquefied petroleum gas (LPG, n = 1), cresol (n = 1), trichloroethylene (TCE, n = 1) and hydrogen sulfide (H2S, n = 5) in 683 cases. Ethanol and acetone levels showed good correlations among right heart/peripheral blood, PCF and BMA with a few exceptions. Inhaled cyanide in a fire fatality and H2S in suicidal inhalation were substantially lower in PCF than in blood and BMA; however, ingested cyanide showed a higher level in PCF. Distribution of inhaled toluene largely varied by case; however, BMA levels were about twice as high as blood levels in abusers (n = 7). Inhaled LPG and TCE were also higher in BMA than in blood, whereas ingested cresol showed similar distributions in blood and PCF. These observations suggest the usefulness of PCF and BMA as alternatives to blood for postmortem toxicological analysis. The inclusion of these materials in routine analysis may be also useful to investigate pharmacokinetics and toxicokinetics in the death process and the influence of postmortem redistribution/diffusion.
The article considers the status of interlibrary co‐operation in Japan in terms of its historical development and future needs. The number of libraries has doubled in the last twenty years. The identification and location of bibliographic information is seen as a particular problem: available tools are discussed and future developments considered. Statistical and background information is provided for a variety of library types: university, public, special, and the major library networks. Special attention is paid to the National Diet Library where a Library Co‐operation Department is seen as addressing some of the major problems. The view of the library in Japan as being an isolated unit with services available to a select group of patrons, is changing, the slow development of interlibrary co‐operation giving way to a growing awareness of the need for increased diffusion and availability of information.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
