It has been shown that none of the small cell lung carcinoma (SCLC) cell lines possess epidermal growth factor (EGF) binding activity on their surface. We have examined several SCLC cell lines for the possibility that they may have EGF receptors but that the receptors are masked by an EGF-like protein factor(s), which may be produced by an autocrine(More)
Starting from the group II RNA phage GA which has an amber mutation in the maturation protein cistron, a spontaneous mutant of group II phage GA, whose serological and electrophoretic properties became similar to those of group I phage MS2, was isolated and analyzed. The mutant has now become sensitive to anti-MS2 serum and resistant to anti-GA serum.(More)
We investigated the effect of number of nitroglycerin (TNG) as patches, containing 5 mg of TNG per sheet, on hemodynamics in 29 adult patients undergoing elective surgery. Patients were randomly allocated to four groups according to the number of the sheets applied (0, 2, 5 and 10 sheets). Hemodynamics as well as plasma TNG concentration were measured at 4(More)
In order to clarify the taxonomic status of an RNA coliphage, MX1 (a serological intermediate between groups III and IV), we examined (i) read-through protein synthesis in a cell-free protein-synthesizing system, (ii) the peptide map of the coat protein and (iii) the RNA sequence in the 3'-terminal region of MX1 RNA. We found that the characteristics of MX1(More)
