Abstract
Increase and decrease of BP could be induced respectively by icv of AII (20#mu#g) and ST-AII (20#mu#g), to a greater entent in SIH than in the normotensive group. Icv AII also increased the ENG of MHb cardiovascular neurons in both the groups, but the increase was significantly greater in SIH group than in the nomotensive one. Iontophoretic application of AII increased the ENG of Hb cardiovascular neurons in both the groups and the increase was also significantly greater in SIH than in the normotensive group. On the other hand, iontophoretic application of ST-AII inhibited the ENG of Hb cardiovascular neurons in the two groups and the inhibition was markedly greater in SIH than in the normotensive rats.
