Private gains and public losses: The distributive impact of urban zoning

The zoning process is a distributive process in which benefits are conferred on some and denied to others. Because zoning decisions are not neutral in their consequences, politicians must take responsibility for the patterns of benefits and costs which result from particular zoning policies. Technical expertise and planning principles cannot be regarded as sufficient grounds on which to base inherently distributive policies. This paper analyses the distributional consequences of two rezoning cases in Toronto to illustrate the trade-offs between neighbourhood preservation and housing opportunity.This is a revised version of a paper presented at the Annual Meeting of the Canadian Political Science Association, London, Ontario, May 1978.     

C6-polymorphism of the sixth component of complement: application to paternity cases (author's transl)]

The results of a study of the polymorphism of the sixth component of human complement by means of isoelectric focusing in polyacrylamide gels with subsequent C-dependent lysis in an agarose overlay containing C6 deficient rabbit serum are reported. The allele frequencies obtained (C6A = 0.613, C6B = 0.379, C6R = 0.008) are in good agreement with those previously published. The mode of inheritance in 47 families with 173 offspring as well as 26 mother-child combinations is in agreement with a formal genetical model: "C6A, C6B, C6A1 and C6B1 at an autosomal locus". The inclusion of this system into a blood group expertise in Germany can be recommended.     

The effect of ethanol and antabus-antabus-alcohol-reaction on histamin and mast cell. Contents of the lung (author's transl)]

Alcohol--orally given in concentrations from 1 to 4 g/kg body-weight--leads to a reduction of mast cells in the guinea pig lung. At the same time a minor decrease of histamine concentration was observed. The incompatibility reaction with alcohol after disulfiram intake (DAR) shows an additional degranulation oft mast cells of the lungs and decrease of histamine-content. So far, there seems little difference between the influence of disulfiram alone and the DAR. Besides thrombocytes and basophile leucocytes, the mast cells of the lung are responsible for the release of histamine and serotonine during higher alcohol concentrations and alcohol-disulfiram-reactions. We think that the intolerance phenomena of humans after alcohol--f.e. in form of flush-reaction--is at least partly related to the concomitant influence oft mast cell-substances.     

Metabolite sensitivity in the methaqualone radioimmunoassay.

Recent literature reflects the increased use of RIA as a qualitative and quantitative tool. This study exemplifies the problems that may arise when this technique is used for quantitation. Caution must be exercised, and a physiological and toxicological understanding of each particular drug is essential to provide credible results. It is evident that the sensitivity and ease of the RIA method for methaqualone makes it invaluable as a screening test, but confirmation and quantitation of this drug must remain with those methods that can quantitate each metabolite.
