 Whilst bacteria and fungi are the main groups involved in decomposition processes, the larger insects additionally provide an important physical disruption of body tissues, which aids the penetration of micro- organisms and speeds the collapse of the body structure.

 Thermal analysis methods have been introduced into forensic sciences only in recent times. Though thermoanalytical instruments have been available commercially for some decades it was not until the beginning of the seventies that forensic scientists became interested in them. At that time some state forensic science laboratories in the Federal Republic of Germany made use of differential thermal analysis for forensic soil investigations. The forensic science section of the city police of ZUrich, Switzerland, applied an instrument (differential thermal analysis and thermogravimetry) for various purposes. Investigations of fibers by means of differential scanning calorimetry were reported by the Centre of Forensic Sciences at Toronto, Canada, and on the characterization of candle-waxes by differential thermal analysis by the Metropolitan Police Forensic Science Laboratory, London, England. Later on some other insti tutions like the Bundeskriminalamt at Wiesbaden, Germany, or the Home Office Central Research Establishment at Aldermaston, England, purchased instruments for one or more of the following thermal analysis methods: differential thermal analysis or differential scanning calorimetry, thermogravimetry, and thermomechanical analysis. . But even now thermoanalytical instruments are not widespread in forensic science institutes and knowledge of their forensic potential seems to be limited. In the following chapters we will give a survey of the most important thermal analysis methods mentioned above, and on current forensic applications and/or fields of actual research efforts.

 Competitive binding techniques such as radioimmunoassay (RIA) are widely used to measure an enormous variety of compounds in biological fluids. Current methods have 1 2 arisen from the pioneering work ofYalow and Berson in the U. S. A. and Ekins in the u. K. Much of the early development was concerned with the analysis of protein hormones, and nearly a decade passed before attention focussed also on small molecules such as steroids and drugs. The potential of immunoassay methods for drug monitoring in clinical and forensic laboratories and in addict treatment programmes resulted in the commercial production of immunoassays for various therapeutic and abused drugs, making the technique available to laboratories lacking the facilities to raise their own antisera and synthesise labelled compounds. However, commercial assays are not only expensive but are restricted in range, and so it is advantageous for a forensic laboratory to have the capability to devise "in-house" immunoassays suited to its particular requirements. This chapter describes the theory and practice of RIA in forensic drug analysis. Much of the theory and some of the practice are applicable to immunoassays in which non isotopic labels are used, but such assays are not described in detail since, to date, the versatility and sensitivity of RIA have made it the immunoassay technique of choice in forensic toxicology. The particular advantages of RIA are its sensitivity and the fact that samples such as haemolysed blood can be assayed with little or no prior preparation.

 Methamphetamine is one of the most widely abused stimulants and together with amphetamine has led to serious social problems. Numerous papers in the fields of medicine, toxicology, pharmacology, sociology, etc. have appeared. In Japan for example about 20,000 to 22,000 persons have been arrested in recent years on suspicion of abuse, smuggling or illegal manufacture of drugs. In other countries, stimulant drugs also present social problems and efforts have been directed toward prevention. Although marked development of analytical techniques in the field of forensic sciences has been achieved, there is a need for a continuous review of recent advances. A review of studies on methamphetamine has therefore been made from the standpoint of forensic toxicology and legal medicine. Attention has been directed to biological samples because analyses and interpretation for the purpose of t.oxicological and As a detailed survey on abuse drugs involving clinical practice are important. 1 methamphetamine and amphetamine has been made by Fishbein and covered the time before 1980, we refer only to data and events appearing after 1980.
