    Notes: Summary HCMV infection diagnosed by the highly sensitive polymerase chain reaction (PCR) technology in blood, urine and skin biopsies of patients after bone marrow transplantation (BMT) correlated with the reconstitution of peripheral blood lymphocytes and dermal immunohistological alterations to evaluate the interaction of viral infection with the recovery of the immune system, as well as with the induction or aggravation of graftversus-host disease (GVHD). In a prospective study 73% of 63 patients showed viremia at a median time of 25 days after BMT. Only 44% of these cases that also presented with a higher frequency of acute GVHD symptoms developed HCMB disease later on. In the skin, similar immunohistological alternations, as well as frequent primary local HCMV infection before the development of cutaneous signs of GVHD, was found, suggesting the direct involvement of anti-HCMV immune responses in the induction of GVHD-associated organ lesions.

    Response ofScolytus multistriatus (Coleoptera: Scolytidae) to α- and δ-multistriatin in Switzerland (1982)

    Notes: Abstract Laboratory bioassays and field tests demonstrated that a Swiss population ofS. multistriatus responded much more strongly to α- than to δ-miltistriatin in combination with 4-methyl-3-heptanol and α-cubebene. High concentrations of brevicomin appeared to replace α-multistriatin in evoking a response byScolytus species, but this effect can be explained by the fact that the brevicomin was contiminated with small amounts of α-multistriatin. Frontalin, another bicyclic ketal, showed no biological activity. Field tests indicated thatS. pygmaeus aggregates to the same attractant mixture asS. multistriatus. S. scolytus also responded preferentially to this mixture, but the relative amounts of α-multistriatin to 4-methyl-3-heptanol do not appear to be as important as forS. multistriatus.
