Compared with the SHR + saline group, the TGD 20 g/kg/d, 40 g/kg/d groups had significant differences (P < 0.01), which reduced the expression of vasoconstrictors TXA2 and Ang II (Figures 5(b) and 5(d)), antagonizing the vasoconstriction of SHR caused by hypertension. The gene discussed is AGT; the disease is hypertensive disorder.
