title: [Effect of intravascular pressure changes on the induction of bone neoplasms in rats].
abstract: The development of bone tumours induced by 3,4-benzpyrene in rats with arterial hypotension and venous congestion was studied. Six months after, osteogenous sarcomas were detected in 36% of animals with normal pressure, in 10%--with arterial hypotension and in 58%--with venous congestion. The differences in the antitumor tissue resistance under chemical blastomogenesis, as well as in cases of transplanted tumours, are supposed to depend on the character of compensatory rearrangements in the microcirculatory bed in response to the intravascular pressure change.
