    Notes: Summary 1. At high concentrations phospholipase A of cobra venom has a direct haemolytic action on washed guinea-pig red cells. The concentration necessary for this effect is one hundred times higher than that required for haemolysis in the presence of the direct lytic factor (DLF). 2. Like guinea-pig red cells, rat erythrocytes are lysed by DLF, but are much less sensitive. A potentiation of haemolysis by the combined action of Phospholipase A and DLF is also seen in rat erythrocytes. Concentrations of DLF 50 times higher and of Phospholipase A 100 times higher than used for guinea-pig red cells are necessary to obtain comparable degrees of haemolysis with rat erythrocytes. 3. The degree of potentiated haemolysis depends on both, the concentration of DLF and the concentration of Phospholipase A. The different susceptibility of red cells from different species to haemolysis by cobra venom thus does not depend on a different sensitivity to one of the two haemolysins alone.

    Identification of the triploid genome by the C-banding method (1976)

    Notes: Abstract We report on cytogenetic studies of a malformed fetus, whose clinical symptoms indicated the diagnosis of triploidy. This was confirmed by chromosome analysis of peripheral lymphocytes of cord blood. Using the C-banding method it was possible to identify the origin of the extra haploid set: marker chromosomes indicate, that nonreduction of the first meiotic division in the father's spermiogenesis most probably leads, to triploidy. However, in our case fertilization of the zygote by two sperms cannot be excluded.
