Histomorphometric indices of the pancreas in intoxication with alcohol and narcotics

The results of histomorphometric examinations of the pancreas in drug- and alcohol-addiction as well as in acute intoxications are described. They show that, in chronic alcoholic intoxication as compared with opiomania, there are more pronounced interlobular sclerosis and lipomatosis, which is manifested by an enlarged middle lobe of the stroma (containing fat and connective tissue fibers), by a higher density of islands of Langerhans and by their higher sectional area. Autolysis and edema of the stroma are more severe in an acute intoxication with drugs than in other cases of fatal outcome. A possibility is demonstrated to differentiate between various types of the so-called long-term exogenous intoxication and to discriminate between different types of thanatogenesis typical of various cases of acute intoxications. Data are presented that demonstrate the advantage of the quantitative analysis of histological preparations over the qualitative one.     

Public Opinion on Federalism in Canada, Mexico, and the United States in 2003

This research reports on public opinion surveys on intergovernmentaland federal issues conducted in Canada, Mexico, and the UnitedStates in March and April 2003. In all three countries, respondentsmost often see their federal government as being the least effective,least efficient, and least trustworthy. Respondents from Canadaappear least supportive of their federal government and mostsupportive of their local governments; those from Mexico appearmost supportive of their state governments; respondents fromthe United States appear more "balanced" in their support ofthe various orders of government. Also, far greater regionaldifferences in opinion exist in Canada than in Mexico or theUnited States. Support for more decentralized federalism isfound to be strong in all these federal countries. This researchalso updates long-term trend data for the United States. Comparedwith respondents from previous years, U.S. respondents in 2003showed a measurable uplick in support for the federal government,compared with state and local governments. This support seemsto be a carryover from the terrorist attacks of 11 September2001.     

Pesticide poisoning initially suspected as a natural death

A pesticide poisoning victim suspected initially as having died a natural death was autopsied. The victim was a 47-year-old male. Macroscopically, signs of acute death and, in particular, general erosion in the mucosa of the airways and esophagus were observed. In the gastric contents, which had a pungent smell and a greenish-brown color, 5.00 g/L of propanil, 1.27 g/L of carbaryl, 0.38 g/L of ethylbenzene, and 0.32 g/L of xylene were detected. In the blood (serum), 21.6 mg/L of propanil, 8.1 mg/L of carbaryl, 1.7 mg/L of ethylbenzene, and 4.0 mg/L of xylene were identified. Postmortem methemoglobinemia (45%) was recognized. The cause of death was considered to have been pesticide poisoning; propanil was probably most responsible for his death. The police considered the case to be "death with illness as the suspected cause." By performing an autopsy, however, we were able to clarify that the cause of death was pesticide poisoning.     

Evidence for use of electroshock devices

The authors tested whether use of an electro shock weapon (stun gun) leaves marks on skin which can be found in an exterior examination. On pig skin such marks could not be produced postmortally. An experiment on one of the authors caused reddish skin marks which persisted for about 2 h. Inability to act as promised by the weapons' manufacturers did not occur in our experiments, exactly as previously described by other authors. Use of an air tester which shoots barbed electrodes ought to produce bleedings if the electrodes actually penetrate the skin.     

Determination of drug levels in larvae of Protophormia terraenovae and Calliphora vicina (Diptera: Calliphoridae) reared on rabbit carcasses containing morphine

Two species of blow flies (Diptera: Calliphoridae) were reared on tissues from rabbits administered different dosages of morphine. These species, Protophormia terraenovae and Calliphora vicina are among the first wave of insects colonizing a dead body. Two series of 3 rabbits were given dosages of 10, 20, and 40 mg/h of morphine over a 3 h period via ear artery perfusion. A morphine blood level plateau was attained after 1 h of perfusion. Two other rabbits were used as controls. Samples of tissues collected from rabbits using a coelioscopic technique were determined to have morphine concentrations similar to those encountered in human overdoses and were correlated with dosages of morphine administered. All samples from control rabbits were negative for morphine. Larvae and puparia of both species were regularly collected from each rabbit for toxicological analysis. Concentrations of morphine in larvae reared on rabbit carcasses containing morphine were significantly lower than concentrations found in the tissues. There was a decrease in concentration in morphine observed in transition from feeding 3rd instar larva to puparium. A correlation between larval concentration and tissue concentration was found only in feeding 3rd instar larvae.
