ABSTRACT
A rare case of suicide in which the victim had been lying along the railway track in a supine position and with extended extremities is described. The wheels of a train caused longitudinal hemisection with complete evisceration. Epidemiological data on train suicides are given and the relationship between this method of suicide and mental illnesses and consumption of alcohol are discussed.

The results of a study of Inter-Alpha-Trypsin Inhibitor (ITI) polymorphism in 281 blood samples are reported in this paper. These samples were taken from healthy individuals of both sexes, unrelated and resident in the Province of Cadiz. The frequency of ITI*1 was 0.617 and of ITI*2 was 0.383. The probability of exclusion in paternity testing was 0.18.

Part I. Cocaine-Lidocaine Mixtures A rapid procedure based on second-derivative UV spectrophotometry is proposed for the simultaneous determination of cocaine and lidocaine. The optimum magnitudes are chosen in terms of response linearity, sensitivity, relative percent error, relative recovery data, and reproducibility. Part II. Cocaine-Procaine Mixtures A derivative spectrophotometric method based on second-derivative ultraviolet absorption spectra has been developed for the simultaneous determination of cocaine and procaine. Several derivative magnitudes have been investigated. A statistical analysis of the results is reported. Part III. Cocaine-Tetracaine Mixtures A simple method has been developed for the simultaneous determination of cocaine and tetracaine by measuring the amplitudes of the positive peak at 286.6 nm and the negative peak at 313.9 nm with respect to zero baseline. Part IV. Cocaine-Benzocaine Mixtures Derivative ultraviolet spectrophotometry has been used for the simultaneous determination of cocaine and benzocaine. Both cocaine and benzocaine can be assayed by measurement of, respectively, the peak-to-peak amplitude D261.4,277.4 and the peak-to-zero amplitude D299.4. The method is applied to simulated street samples of cocaine.

A rapid second-derivative procedure for distinguishing cocaine and other local anesthetics is described. This technique appeared to be particularly useful in the detection of cocaine in binary mixtures. It is of great value in forensic toxicology, resolving cocaine-lidocaine, cocaine-procaine, cocaine-tetracaine, and cocaine-benzocaine mixtures, for which zero-order UV spectroscopy fails.
