    Notes: Abstract Based on the hypothesis of a relationship between the concentration of trace amines like tetrahydroisoquinolines (TIQ's) and β-carbolines (BC's) in the brain and an increased voluntary ingestion of ethanol, the concentrations of ethanol, acetaldehyde and harman (a β-carboline) were examined in a group of 20 alcoholics. The patients excreted a higher amount of harman into the urine than non-alcoholics on the day of admission (harman-1) as well as at the end of the detoxication period, 14 days later (harman-14). Certain factors were related to the increased excretion of harman by alcoholics: The younger the patient when he/she consumed ethanol for the first time, the higher the concentration of acetaldehyde in the blood and the amount of harman (harman-14) excreted in the urine. Furthermore, the younger the patient when he/she was intoxicated with ethanol for the first time the higher the amount of harman (harman-14) in the urine. Patients with first grade relatives who were alcoholics excreted more harman (harman-14) than those without such relatives. The following variables were not related to harman-14: The average amount of ethanol consumed daily during the 6 months prior to admission, the presence of signs of intoxication and symptoms of withdrawal at admission to hospital, and the consumption of other psychotropic substances. A negative correlation was found between the state of the liver, as assessed by liver histology and γ-glutamate transferase (γ-GT) levels, and the concentration of harman in the urine. Thus, some events in the patient's history as well as the state of the liver are important for the increased excretion of harman into urine of alcoholics.

    Notes: A technique for the preparation of entire intestinal mucosal sheets is described that renders the population of crypts accessible for two-dimensional study. We have applied the technique to demonstrate the mosaic crypt populations in the intestinal epithelium of mouse aggregation chimeras, using the lectin Dolichos biflorus agglutinin (DBA) as a strain-specific histochemical marker.

    Notes: This essay summarizes recent advances made in the analysis of mosaic patches in chimaeric epithelia of the mouse. The conclusions drawn from the observed patterns are relevant to the behaviour of expanding cell populations during tissue growth and homeostasis. References are made to clonal analysis of Drosophila.

    Notes: Clonal studies of adult chimaeric mouse epithelium have demonstrated the monoclonal composition of crypts of Lieberkühn(1). In neonatal life, however, polyclonal crypts have been found, indicating that crypts are of polyclonal origin(2). We here relate these findings to studies of mosaic tissues which have addressed the question whether solid tumours are of monoclonal or polyclonal origin (ref. 3 for review, 4). The issues has so far remained unresolved because the expected frequencies of polyclonal tumours, given polyclonal origins, have not previously been estimated. A general approach for the calculation of such expected values is suggested. The consistent reports of tumours with polyclonal components suggest that autocrine or paracrine mechanisms play an important role during tumorigenesis.
