Q: Question: Is nitric oxide-dependent renal vasodilatation altered in rat with rHuEpo-induced hypertension?
Answer: The analysis of our results seems to indicate that the endogenous NO system activity was enhanced in rHuEpo-induced hypertension in rats with normal renal function and a resistance to NO was not developed in renal circulation. Further studies seem to be necessary to better clarify the exact mechanisms underlying the development of rHuEpo-induced hypertension.

A:
no
