A technique is described for the sequential determination of Gm/Km and ABO blood groups from the same piece of bloodstained thread. Experience with applying the technique to ‘casework’ material is discussed.

The thermostability of ABO blood-group antigens in human dental pulp is described. The ability of the enamel and dentine to protect the ABO(H) antigens from thermal damage has also been estimated mathematically.
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 inquires 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.
The normal levels of bromine in human tissue are given and their use in the interpretation of levels found when over-exposure is a possibility is described. Bromine is “normally” distributed in human tissue as are essential trace elements. This allows a bromine (μg) to chlorine (mg) ratio to be established (3.2) above which bromine exposure must be considered. The bromine concentrations in sections of hair can be used to establish the time of administration even when small amounts are ingested, but owing to the long halflife (about 15 days) found in human tissue interpretation after multiple doses may be difficult.
Phosphoglucomutase1 and 6-phosphogluconate dehydrogenase types present in human red cells were also found in human hairbulbs. These phenotypes were detectable up to 2 weeks following extraction of the hair. The results are useful in medicolegal individualization of the human hair.
We confirm the great stability of the A and B antigens in dried blood, and the markedly lesser stability of antigen H.
We demonstrate that it is possible to determine the immunoglobulin groups Gm(1), Gm(10) and Km(1) — formerly Inv(1) — in bloodstains 29 to 33 years old.
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.
