ABSTRACT
A total of 59 people with chronic epilepsy recalled autobiographical episodes and personal facts (such as the names of friends or teachers) from various lifetime periods. Also tested was their verbal fluency and their fluency in generating items from semantic categories (animals, vegetables, US presidents, and British prime ministers). Results of a cluster analysis and a common factor analysis confirmed a dissociation between the retrieval of autobiographical information and that of nonpersonal semantic information. There was a similar dissociation between the recall of personal episodes and the recall of the personal information, but the corresponding factors were highly correlated with one another. Finally, verbal fluency performance was significantly correlated with the retrieval of personal information, personal episodes, and common objects, but not with that of public figures. The constituent structure of autobiographical fluency is extremely robust across different populations.

The proposal that Kaposi's sarcoma undergoes cellular transformation from early to late stages was studied with argyrophilic nucleolar organizer regions, proliferating cell nuclear antigen/cyclin, and immunoperoxidase staining for factor VIII-related antigen. Staining of argyrophilic nucleolar organizer regions was significantly increased in the plaque/nodular stage compared to the patch stage. The endothelial-selective marker factor VIII-related antigen stained more intensely in patch stage lesions. This was inversely correlated with staining of argyrophilic nucleolar organizer regions. Proliferating cell nuclear antigen/cyclin staining did not correlate with tumor stage or with factor VIII-related antigen. The changes in argyrophilic nucleolar organizer regions and factor VIII-related antigen staining are evidence for cellular transformation in Kaposi's sarcoma.
