Abstract:
0.05).The concentration of urinary KYNA,metabolite of the KYN,was significantly lower in SHRs compared to WKYs(7.8?1.8 vs 19.9?3.5 ?mol/24 h P=0.013).Both KAT activity in renal cortex and KYNA content in urine were negatively correlated to blood pressure(r=-0.418,P=0.023;r=-0.723,P=0.001).Conclusion The declined activity of KAT in renal cortex and the deficiency of KYNA concentration in urinary may affect blood pressure regulation in SHR by renal metabolite of the KYN.
