Photodynamic effect of toluidine blue on MM virus. 1976

D Smelt, and R Repanovici, and A Pascaru, and R Portocală

The photodynamic effect of toluidine blue (TB) was studied on MM virus cultivated in L cells and on the RNA extracted form MM virus inoculated to mice by intracerebral route. MM virus infectivity is completely inhibited by the photodynamic action of TB, due to lesions at the molecular level of the viral RNA.

UI MeSH Term Description Entries
D008027 Light That portion of the electromagnetic spectrum in the visible, ultraviolet, and infrared range. Light, Visible,Photoradiation,Radiation, Visible,Visible Radiation,Photoradiations,Radiations, Visible,Visible Light,Visible Radiations
D010948 Viral Plaque Assay Method for measuring viral infectivity and multiplication in CULTURED CELLS. Clear lysed areas or plaques develop as the VIRAL PARTICLES are released from the infected cells during incubation. With some VIRUSES, the cells are killed by a cytopathic effect; with others, the infected cells are not killed but can be detected by their hemadsorptive ability. Sometimes the plaque cells contain VIRAL ANTIGENS which can be measured by IMMUNOFLUORESCENCE. Bacteriophage Plaque Assay,Assay, Bacteriophage Plaque,Assay, Viral Plaque,Assays, Bacteriophage Plaque,Assays, Viral Plaque,Bacteriophage Plaque Assays,Plaque Assay, Bacteriophage,Plaque Assay, Viral,Plaque Assays, Bacteriophage,Plaque Assays, Viral,Viral Plaque Assays
D004686 Encephalomyocarditis virus The type species of CARDIOVIRUS causing encephalomyelitis and myocarditis in rodents, pigs, and monkeys. Infection in man has been reported with CNS involvement but without myocarditis. EMCV

D014052 Toluidines Any of three isomeric compounds (ortho-, meta-, and para-) containing a benzene ring with a methyl and amino group attached to it. They are suspected CARCINOGENS. Aminotoluene
