At post mortems performed in cases of cot death, the cause of death has been established as due to a variety of pathological changes. In connection with the anamnesis data, inflammation in the region of the respiratory system, especially of the lungs, infections of the gastrointestinal tract, otitis media and electrolyte shifts can in many cases be traced back to a common origin, if we assume a bacterioenterotoxin poisoning (which takes a different course in infants than in older children or adults).

Extensive inquiries prior to the post mortem, autopsies performed always by the same method, as well as all the ensuing examinations, are indispensable in order to explain the cause of the sudden death and to make sure that the results of the post mortem are not influenced by the importance the pathologist attributes to a certain method of examination.

Bei der Obduktion plötzlich verstorbener Säuglinge wird eine Vielfalt krankhafter Veränderungen als Ursache des Todes festgestellt. Entzündungen im Bereich der Atemwege, insbesondere der Lungen, Infekte des Magen-Darmtraktes, Otitis media, Elektrolytverschiebungen, in letzter Zeit auch sogenanntes gelbes Fett u.a. können in Zusammenwirken mit den Angaben zur Vorgeschichte in vielen Fällen durch die Annahme einer Bakterien-Enterotoxinvergiftung, die im Säuglingsalter anders verläuft als beim grösseren Kind oder Erwachsenen, auf einen gemeinsamen Ursprung zurückgeführt werden.

Ausführliche Ermittlungen vor der Obduktion, die in gleicher Art und Weise durchgeführte Leichenöffnung sowie der sich daran anschliessender Untersuchungen sind für die Klärung der Ursache des plötzlichen Todes unabdingbare Voraussetzunge, schon damit die Ergebnisse nicht der Bedeutung, die der Obduzent einer bestimmten Untersuchungsmethode beimisst, entsprechen.

The authors describe a Polish family (three generations) with a silent gene P^o of human red cell acid phosphatase. The phosphatase levels of 4 family members were about half the normal value.

Analysis of Cannabis sativa L. grown 1300 meters above sea level shows that the amount of propyl cannabinoids is higher than the respective pentyl homologues. High percentages of pentyl and propyl cannabichromenes were produced under these growing conditions.

The enzyme-multiplied immunoassay technique (EMIT) was compared with the gas-liquid chromatographic (GLC) method in the analysis of 130 urine samples from subjects receiving methadone treatment and non-methadone controls. The GC method allowed the quantitation of 2-ethylidene-1,5-dimethyl-3,3-diphenylpyrrolidine, the major metabolite of methadone. A good correlation was found between the two methods. The advantages of using the EMIT system are discussed.

During the last decade there has been philosophical acceptance of the concept that the state of brain death is equivalent to total patient death. The application of this concept to clinical medicine has been associated with major problems in both the diagnosis of brain death and the medical management of the brain dead patient. In our experience with 176 consecutive cases of suspected brain death over a seven-year period, we have found that a standardized protocol applied by experienced clinicians will minimize these problems.

An unequivocal determination of heroin in simulated street samples is deseribed. Heroin is separated from the active excipients and contaminants by reverse-phase high-performance liquid chromatography. An infrared spectrum is obtained using semimicro-sampling techniques on the heroin fraction collected. The total analysis time is 50 minutes.

Two cases of chloroquine intoxication are reported. Chloroquine concentrations in blood and in various tissues, determined by spectrophotometry and thin-layer chromatography, are discussed in the light of existing literature.
