[Transformation by SV 40 virus sensitizes fibroblasts of human skin to the lytic action of H-1 parvovirus]. / La transformation par le virus SV40 sensibilise les fibroblastes de peau humaine à l'action lytique du parvovirus H-1.

Human skin fibroblasts which are naturally resistant to Parvovirus H-1 can be lysed by this virus after SV40 transformation. This observation raises the possibility that oncosuppression by Parvovirus involves a direct oncolytic effect.

[Reactivation of gamma-ray irradiated parvovirus H-1 in cells of patients with ataxia telangiectasia and Huntington's chorea]. / Réactivation du Parvovirus H-1 irradié aux Rayons gamma dans les cellules de patients atteints d'ataxia telangiectasia et de la chorée de Huntington.

Parvovirus H-1 was used to probe the cellular radiosensitivity of two human degeneration syndromes AT and HC. No difference in the survival of gamma irradiated H-1 was detected between skin fibroblasts from such patients and from a normal individual. However, AT and normal cells were distinguished by the fact that the reactivation of irradiated H-1 could be increased by UV or X-irradiation of the latter but not of the former cells.
