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.  相似文献

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.  相似文献
