inhibition of 7,12-dimethylbenz(a)anthracene-induced tumors in syrian hamsters by prior infection with h-1 parvovirus. | hamsters, given injections s.c. at birth of h-1 parvovirus and 1 month later given a single injection of 7,12-dimethylbenz(a)anthracene, had a 38% tumor incidence compared with a 95% incidence in animals receiving 7,12-dimethylbenz(a)anthracene alone. thus, h-1 which, it has already been shown, invokes a resistance to the incidence of spontaneous and adenovirus-induced neoplasms in hamsters also produces a suppression of a carcinogen-induced tumor in these animals; this suggests that the h-1-ind ... | 1982 | 6805941 |
