A comparative study of art expression of schizophrenic, unipolar depressive, and bipolar manic-depressive patients. | The literature on art productions from psychiatric patients consistently suggests that specific graphic characteristics distinguish among various major diagnostic groups. These hypothesized differences are summarized. Systematic collection of art productions as part of separate research programs studying affective psyc... | 772,171 | [

A critique of the evidence for active host defence against cancer, based on personal studies of 27 murine tumours of spontaneous origin. | Extensive experience with isotransplants of 27 different tumours (leukaemias, sarcomata, carcinomata), all of strictly spontaneous origin in laboratory bred mice of low cancer strains CBA/Ht and WHT/Ht, has revealed no evidence of tumour immunogenicity. Of approximately 20,000 maintenance transplants, none failed and n... | 773,395 | [
