Evaluation of a lactate dehydrogenase-nitro blue tetrazolium method of detecting unapparent myocardial infarction using a standardised sampling technique

Using a standardised block technique, the microscopic lactate dehydrogenase-nitro blue tetrazolium (LDH-nitro BT) and conventional haematoxylin and eosin staining methods were used to investigate the presence of myocardial infarction in a series of fifty forensic autopsies. The microscopic LDH-nitro BT method was found to be reliable; however, it did not reveal the presence of myocardial infarction in any of the cases where this had not been suspected.     

The determination of glyoxalase I phenotypes in human bloodstains

A method is described for the determination of glyoxalase I phenotypes in liquid blood and dry bloodstains. The frequencies of glyoxalase I phenotypes in various populations of S.E. England are included.     

Property rights and unemployment insurance reserves

Unemployment insurance (UI) laws have recently come under considerable criticism for fostering employment disincentives. Imperfections in the experience rating tax schedule has been the primary causal factor behind most of these allegations. In particular, the insurance subsidies created by the tax schedule have been blamed for distorted labor markets and for increased layoffs.This article proposes that a property rights system be established for UI reserves which would enable a firm with an unemployment insurance reserve surplus to lend voluntarily to a firm in need of reserves. Such a system would allocate reserves more efficiently and eliminate some of the disincentives effects of the current unemployment insurance scheme. A property rights system would be a second best solution to perfecting the present unemployment insurance system and making it actuarially sound. However, assigning rights to UI reserves can be implemented without challenging the special interests of the politically dominant industries that have been responsible for maintaining the imperfections in the UI system for 50 years.     

Battered wives,lawyers, and district attorneys: An examination of law in action

The legal services received by 146 Milwaukee women who had been beaten by their husbands, but had been free of the violence for at least a year, are described and evaluated. Of these women 106 recieved legal help in connection with at least one battering incident. Some women saw more than one member of the legal profession, so the total number of legal contacts among the 106 women was 255. There is evidence that lawyers and district attorneys were most likely to be used by those battered women for whom the use of personal strategies and informal help sources (such as family and friends) were ineffective in combatting the violence. Contrary to the negative image of lawyers and district attorneys found in the literature on wife beating, most legal service contracts were rated as very or fairly successful by the battered women. The more difficult and severe the situation, the higher the success ratings given to lawyers and district attorneys by their clients. Despite the generally positive reactions that most beaten women had to lawyers and district attorneys, there were many negative incidents reported, including district attorneys who refused service or discouraged battered women from filing charges, and lawyers who sided with the aggressors or attempted to meet their personal and professional needs at the expense of their clients. These incidents remind us that it would be useful to educate legal professionals about the nature of family violence, the situation and needs of battered women, and the legal and ethical responsibilities that lawyers and district attorneys have when they are contacted by battered women.     

Hypernatremia due to amniotic fluid embolism during a saline-induced abortion

A case of fatal amniotic fluid embolism leading to hypernatremia during a hypertonic saline-induced abortion is reported. This sequence of events has not, to our knowledge, been previously reported. Hypernatremia as a diagnostic aid for amniotic fluid embolism is discussed.     

Detection of drugs using XAD-2 resin. II:Analysis of liver in medical examiner's cases

Liver tends to concentrate drugs in quantities generally higher than those found in blood or other body compartments. This fact as well as the general availability of liver in postmortem cases makes it an important specimen for comprehensive toxicologic investigation. A scheme for the analysis of liver for drugs with tissue hydrolysis, XAD-2 resin extraction, and TLC has been developed and the parameters affecting recovery have been studied. The hydrolysis of liver specimens at various pH conditions resulted in an improved recovery for morphine by using pH 2 (2N hydrochloric acid). Recoveries of barbiturates, codeine, and meperidine were essentially the same at pH 2 and pH 3. A considerable loss (22 to 55%) was observed for four drugs (pentobarbital, morphine, codeine, and meperidine) as a result of drug binding to the tissue pellets during the process of centrifuging the liver homogenates. This method is recommended as a comprehensive screening procedure for drugs in liver tissue. For quantitative purposes, however, it is necessary to determine a correction factor for all the losses occurring at the various steps of the procedure. This procedure compared favorably with other procedures for liver analysis reported in literature.
