[Hypotensive and edematogenic effects of carrageenan in the irradiated rat].
Iota carrageenan induces the same hypotensive effect in leucopenic and thrombopenic rats as in normal animals. This hypotensive activity depends on kininogen-kinins activation. In the irradiated rats, the inflammatory response to iota carrageenan is reduced. The blood cells are thus responsible of the major part of the late inflammatory effect. There is non parallelism between this hypotensive and the oedematogen activities of iota carrageenan in the rat.
