The role of epoxyeicosatrienoic acids in blood pressure and renal function regulation in the experimental models of hypertension
 Honetschlägerová, Zuzana ; Čertíková-Chábová, Věra (advisor) ; Zicha, Josef (referee) ; Maxová, Hana (referee)
Introduction: Epoxyeicosatrienoic acids (EETs) are converted by the enzyme soluble epoxid hydrolase (sEH) to the biologically inactive dihydroxyeicosatrienoic acids (DHETs). EETs are significantly involved in the control of blood pressure, they influence vascular tone and renal transport mechanism. sEH inhibitor reduce blood pressure by increasing the bioavailability of EETs in many models of hypertension. Aim of the study: To determine that sEH inhibitor decreases blood pressure and improves the renal function during the development of malignant hypertension in transgenic rats after the induction of the mouse renin gene. Methods: Hypertension in Cyp1a1-Ren-2 transgenic rats was induced through a dietary administration of the natural xenobiotic indole-3-carbinol (I3C, 0.3 %) for 3 and 11 days. I3C activates the renin gene. At the same time, during a three-day induction of hypertension, the inhibitor of nitric oxide synthase L-NAME (600 mg/l) was administered in drinking water. The sEH inhibitor c-AUCB was given in drinking water at a dose of 13 or 26 mg/l, starting 48 hours before the initiation of I3C and L-NAME administration. Radiotelemetric measurement of blood pressure was performed and renal excretory parameters were monitored in the conscious animals. The effects on renal hemodynamics and...
