Key result
Medium and high dietary doses of nitrite significantly increased blood iron-nitrosyl-hemoglobin levels and attenuated L-NAME-induced renal injury and proteinuria in hypertensive rats.
Why the study?
Does dietary nitrite improve renal injury and restore NO levels in L-NAME-induced hypertensive rats?
Does dietary nitrite improve renal injury and restore NO levels in L-NAME-induced hypertensive rats?
Dietary nitrite-derived NO generation may serve as a backup system to protect against renal injury when the endogenous nitric oxide synthase system is compromised.
No takes yet. Share an insight, caveat, or question.
May support nitrite-derived NO as backup in NOS-impaired hypertension; hypothesis-generating, requires human trials before any clinical consideration.
Kanematsu et al. (2008) studied L-NAME-induced hypertension and renal damage. Dietary nitrite vs. L-NAME alone was evaluated on Blood NO levels (iron-nitrosyl-hemoglobin) and renal injury. Medium and high dietary doses of nitrite significantly increased blood iron-nitrosyl-hemoglobin levels and attenuated L-NAME-induced renal injury and proteinuria in hypertensive rats.
