Clonidine 106-115 angiotensinogen Rattus norvegicus 17-22 10974488-9 2000 Previous treatment with clonidine attenuated the action of ANGII in reducing the sodium, potassium and urinary volume, whereas previous treatment with yohimbine attenuated the effects of ANGII but with less intensity than that caused by clonidine. Clonidine 24-33 angiotensinogen Rattus norvegicus 59-64 10974488-11 2000 The injection of yohimbine and prazosin, which was done before the injection of clonidine, attenuated the effect of clonidine on the ANGII mechanism. Clonidine 80-89 angiotensinogen Rattus norvegicus 133-138 10974488-11 2000 The injection of yohimbine and prazosin, which was done before the injection of clonidine, attenuated the effect of clonidine on the ANGII mechanism. Clonidine 116-125 angiotensinogen Rattus norvegicus 133-138 10974488-12 2000 The results of this study led us to postulate that when alpha-2-adrenergic receptors are blocked, the clonidine may act on the imidazoline receptors to produce its effects on the ANGII mechanism.
