Nucleotide sequence of a Sendai virus genome region covering the entire M gene and the 3' proximal 1013 nucleotides of the F gene.

We determined the sequence of the 2,138 nucleotides in the Sendai virus genome just following the 3' proximal 3,686 nucleotides which we had previously reported (Nucleic Acids Res. 11, 7317-7330, 1983). This covers the entire third gene of 1,173 nucleotides and the 3' proximal 1,013 nucleotides of the fourth gene. Like the NP and P+C genes, both the third and fourth genes start from consensus sequence R1 (3'-UCCCAC(or UA)UUUC) at the 3' end and the third gene terminates with consensus sequence R2 (3'-AUUCUUUUU) at the 5' end. The third gene was identified as M, and the deduced 348 amino acids indicated that the M protein is rich in basic residues and has hydrophobic domains near the C-terminal. The fourth gene, although sequencing is not complete yet, was identified as F, since a large open reading frame found in the gene contains the characteristic sequence of 20 amino acids located at the N-terminal of the F1 protein. Analyses of the amino acid sequence suggested that the structure of the F gene product is NH2-signal peptide-F2-F1-COOH.

A cytochemical study on the salivary gland pleomorphic adenoma (mixed tumor) and the fetal and adult salivary gland.

We studied the pleomorphic adenoma of the salivary gland ultrastructurally and cytochemically [Mg2+-activated adenosine triphosphatase (Mg2+-ATPase)], compared it with normal human fetal and adult salivary glands, and evaluated the histogenesis of this tumor. In the adult salivary gland, reaction products shows Mg2+-ATPase activity were localized in the plasma membranes of myoepithelial cells adjacent to the acinar cells or intercalated duct cells. However, in the salivary gland of the 16-week fetus, they were seen along all adjoining plasma membranes of the cells of terminal buds and duct-like structures. The present case of pleomorphic adenoma comprised two histological components: solid and myxomatous areas. Reaction products were seen along adjoining plasma membranes of both light and dark cells in solid areas.

Early physiotherapy in the treatment of spastic diplegia.

This study reports the effect of early physiotherapy, using Vojta's method, on children with spastic diplegia. Eight children with spastic diplegia (in spite of early treatment which was started before nine months of age) were compared with 21 children with spastic diplegia in which treatment was started between nine months and three years of age. The average age of starting to walk was eight months earlier in the group treated early, although they had more severe complications. They tended to walk steadily with a gait pattern which was quite different from the classical pattern. All of the early treated patients had confirmed organic brain damage with abnormal CT scan or microcephaly. In conclusion, Vojta's method of treatment is one system which improves the prognosis for walking if performed early.

Lymphotropic papovavirus transformation of hamster embryo cells.

Hamster embryo cells were transformed by African green monkey lymphotropic papovavirus (LPV). The transformed cells contained intranuclear T-antigens demonstrable by fluorescent antibody staining with hamster anti-LPV serum. Analysis of uncloned and cloned lines of transformed cells for LPV sequences revealed that the viral DNA was present as free nonintegrated and integrated genomes; there were approximately 10 copies of free DNA and about one to two copies of integrated genomes per cell. The cells were highly tumorigenic when inoculated into hamsters and produced progressively growing tumors in 100% of newborn or 10-day-old hamsters that were inoculated with LPV-transformed cells. The serum from tumor-bearing hamsters reacted with LPV-transformed cells and also showed a weak reaction with simian virus 40-, BK virus-, and JC virus-transformed cells, thereby showing an antigenic relationship with the T-antigens of other primate polyomaviruses. The large T-antigen of LPV was found to be an 84,000-molecular-weight protein which was immunoprecipitated by hamster anti-LPV (antiviral) as well as by tumor serum.

Analysis of T antigen and viral DNA in mouse cells transformed by K virus, a nononcogenic murine papovavirus.

A tumorigenic line of mouse cells transformed by the nononcogenic murine K papovavirus was established and characterized. Tumor-bearing animals produced antibody specific for K virus-transformed cells; the K virus T antiserum did not react with polyomavirus-transformed cells. Immunoprecipitation of the T antigen in the transformed cells revealed large T antigen (molecular weight 84,000). About 10 to 15 copies of K virus DNA were found to be integrated in the cellular DNA.
