Skeletal remains of Dr. Eugenio Antonio Berríos Sagredo.

It is often noted that even a well-designed osteological technique may not provide accurate results when applied to single forensic cases. Case studies are ideal to test if this concern is valid, and forensic anthropology is a testing ground for applying a population based standard to individual skeletal remains. Secondly, the increasing role anthropologists have played in forensic sciences has aided the medicolegal disciplines in a number of ways. For example, identification of skeletal remains is now more accurate than ever before. Many of these cases have brought perpetrators to court for justice. The purpose of this paper is to use osteological techniques to analyze skeletal remains and make a positive identification. The victim was found partially buried in the sand near El Pinar, Uruguay in 1995. The analysis indicated that the victim was a 45-year old, white, male who was about 170cm tall. Based on preliminary evidence that the victim might be Dr. Eugenio Antonio Berríos Sagredo, a digital superimposition was made using the victim's photograph and the unknown skull. This examination revealed that the skull corresponded consistently with the individual in the photograph. Results were supported by the fact that personal belongings, such as a medal and wrist watch, also pointed to the same individual. Dental records and radiographs when made available later also indicated the same identity. Dr. Berríos was accused of making nerve gas during the dictatorial regime of former Chilean President General Augusto Pinochet. It was also alleged that he made bombs that killed a Spanish diplomat in his laboratory and a Chilean diplomat in Washington, DC. Many complex techniques are often needed to make a positive identification and such was the case for this study. Because of the nature of anthropology as a holistic discipline, such complexity is an integral part of human biology and behavior and can be used successfully in the forensic sciences and medicolegal investigations.

Some recollections of Porton in World War 1. Commentary.

Chemical weapons now regularly feature in news reports and the threat from them has become widely recognised by the public at large. Terrorist actions such as the Tokyo subway incident in 1995, coupled with the persistent use of agents such as sulphur mustard and Sarin by the Iraqi regime over the last 20 years in the Iran/Iraq war and against the Kurds of Northern Iraq, make it easy to think that chemical weapons are a new phenomenon. This paper reminds us that many chemical agents were developed during WWI; indeed the first use of a chemical agent was the release of chlorine gas--a choking agent--by the Germans over the battlefields of Ypres in 1915. Porton Down remains at the very heart of chemicals and biological weapons research, albeit in a purely defensive capacity; few of the old buildings remain and the idyllic lifestyle in the Officer's Mess at Idmiston Manor has long since disappeared. These recollections provide a fascinating insight into scientific research at the time of World War I.

[The development of neurotoxic agents as chemical weapons during the National Socialist period in Germany]. / Desarrollo de agentes neurotóxicos como herramientas de guerra química durante el período nacionalsocialista alemán.

INTRODUCTION: The discovery and development of the so-called 'nerve agents' (neurotoxic substances to be used as weapons) took place in the Third Reich, largely thanks to the vast amount of progress being made in pharmacology in Germany at that time, both in academic and industrial terms. Furthermore, successive National Socialist governments set up a collaborative network made up of the academia, the chemical industry and military chiefs that also favoured this line of research. DEVELOPMENT: The first neurotoxic substance to be incorporated into the category of 'chemical warfare agent' did so almost wholly by chance. As part of the work being carried out on organophosphate-type pesticides and insecticides, Gerald Schrader, a chemist at the I.G. Farben company, synthesised tabun (ethyl N,N-dimethylphosphoramidocyanidate) and an incident involving accidental contamination of laboratory staff with this substance highlighted its potential toxicity. The same group of researchers later synthesised another substance with the same properties, sarin (isopropyl methylphosphonofluoridate). Both agents were studied for use as chemical weapons by Wolfgang Wirth. At the same time, a group led by Richard Kuhn, who won the Nobel Prize in Chemistry in 1938, synthesised pinacolyl methylphosphonofluoridate, otherwise known as soman. CONCLUSIONS: Pharmacological studies confirmed that the neurotoxic mechanism of action of these substances was the irreversible inhibition of the enzyme acetylcholinesterase, which is responsible for metabolising acetylcholine. Results also showed that an excess of this neurotransmitter led to a continuous over-stimulation of the cholinergic (nicotinic and muscarinic) receptors, which is what triggers the appearance of the wide range of symptoms of poisoning and their swift fatal effect.

The Aum Cult leader Asahara's mental deviation and its social relations.

This paper is a further discussion of the author's previous reports on the crimes committed by the Asahara-Aum Cult. First, the motivations of Asahara-Aum crimes, in particular those of murders, and their abnormality beyond the realm of criminology are ascertained. Second, psychopathology of the leader, Asahara, was considered, and it was assumed that Asahara was affected with the syndrome of pseudologia phantastica which was confirmed by his strange attitude during his trials. Third, the mental status of Asahara after the first trial was investigated, and some evidence was found that his mental status was so severe as to be 'unfit to plead' that psychiatric evaluation and treatment would be necessary. Fourth, the reasons for making people, in particular scientific elites, fascinated with Asahara and the Aum Cult were scrutinized and some clues were described. Finally, the problem that Aum has survived under the name of Aleph, how heavy capital punishment for Leader Asahara is appropriate, and that reparations for victims of Asahara-Aum crimes are urgent from the standpoint of social psychiatry, are discussed.
