Catamnesis of patients with Kanner's early infantile autism syndrome

By means of a follow-up study the author studied 28 patients who at the age of 3-6 years were diagnosed as suffering from early infantile autism. In 6 cases the mental state of patients was characterized by traits of dissociated oligophrenic-like defect with preserved autistic forms of contacts, residual disorders of the syndrome of Kanners early autism, simbiotical dependency from the parents. In 15 cases there was a personality distortion, with traits of autism, emotional poorness, motor insufficiency, indifferent negativistic forms of contacts, mental retardation of the pseudooligophrenic type. In 7 cases there was a formation of a psychopathic state of a schizoid type.

Poly (A)-rich ribonucleoprotein complexes from HeLa cell messenger RNA

Polyribosomal messenger RNA from HeLa cells contain 3'-OH-terminal polyadenylate sequences approximately 133 nucleotides in length (weight average). When analyzed at the ribonucleoprotein level of organization these poly(A)-rich sequences are found to contain tightly bound proteins. These proteins remain associated with the poly(A)-rich RNA during affinity chromatography of RNase A and T1-digested polyribosomes on poly(U)-Sepharose in 0.5 M NaCl, and co-elute from the column with the RNA at 50% formamide. Controls establish that the co-purification of the proteins with poly(A) on poly(U)-Sepharose requires the molecular integrity of the poly(A). Polyacrylamide gel electrophoresis resolves the poly(A)-specific proteins into two components of 74,000 and 62,000 molecular weight. The larger protein is the same size as that previously reported to be associated with poly(A)-rich sequences in HeLa heterogeneous nuclear RNA (Kish, V.M., and Pederson, T. (1975), J. Mol. Biol. 95, 227-238). It is concluded that both HeLa nuclear and polyribosomal poly(A) sequences have a protein (62,000 molecular weight) associated with poly(A) appears to be confined only to messenger RNA.
