    Physiological salines and the mechanical properties of trout red blood cells (1986)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Suspensions of rainbow trout erythrocytes in different physiological salines were compared with respect to their haematological and filtration properties.A method is described for the suspension of erythrocytes in Cortland saline which has proved suitable for studies of their mechanical properties over periods of several hours.Significant differences were found between whole blood samples taken during cannulation and after several days recovery, particularly mean cell volume, frequency distribution of red cell volumes and the pore passage time through nucleopore filters. These differences were also found using red cell suspensions of the same bloods. The pore passage time of whole blood sampled during cannulation or its suspensions is less than that of recovery blood although its mean cell volume is greater.

    Inhibitory effect of flavonoids on DNA-dependent DNA and RNA polymerases (1988)
    Springer
    Cellular and molecular life sciences 44 (1988), S. 882-885

    Notes: Summary Flavonoids, (−)-epigallocatechin (1), myricetin (2) and quercetin (3), were investigated for inhibitory effects onE. coli DNA polymerase I and T7 bacteriophage RNA polymerase. In both DNA and RNA synthesis,1 and3 inhibited enzyme reactions by non-competitive and mixed type inhibition respecitively, with regard to template DNAs. Myricetin (2) inhibited DNA and RNA polymerase reactions by mixed type and competitive type inhibition, respectively, with template DNAs. It was suggested that2 interacts with covalently closed/circular DNA.

    Grafted granule and Purkinje cells can migrate into the mature cerebellum of normal adult rats (1988)

    Notes: Summary Cerebellar primordia of different ages (embryonic days of 14 to 20) were transplanted into cerebella of normal syngeneic adult rats (Fischer 344). After 1–12 months (mostly 5–6 months), the host brains were examined by light and electron microscopy. In about 80% of our successful experiments, grafted Purkinje and/or granule cells migrated into the host molecular layer. Some granule cells migrated down along host Bergmann glia, reminiscent of their normal developmental migration route. Other granule cells migrated along astroglial processes that ensheathed capillary walls. Some grafted Purkinje cells were also located ectopically in the host molecular layer. They were identified as graft origins autoradiographically. This migration seemed to be encouraged under conditions where the subjacent host Purkinje cells had been lost. Where the grafted Purkinje cells were located on top of the host molecular layer, their primary dendrites faced vertically downwards into the host molecular layer. However, the position of the apical poles of migrated Purkinje cell bodies in the deeper aspect of the molecular layer varied considerably, suggesting that the orientation of the Purkinje cell dendrites is probably determined by the availability of afferent fibers. Thus, the present study has demonstrated that Purkinje and granule cells can migrate from embryonic cerebellar grafts into the molecular layer of the normal, adult host rat cerebellum.
