Fig 1: Effect of S30+LGA1 on vascular metabolism marker levels in the serum of OVX rats. (A) Endothelin-1 (ET-1) is measured as a serum marker of vasoconstriction. (B) Endothelial nitric oxide synthase (eNOS) is measured as a serum marker of vasodilation. Data are presented as the mean ± standard deviation (SD). **** p < 0.0001 compared with the OVX group. OVX, ovariectomized; E2, 17β-Estradiol; S30, soybean germ extract; LGA1, Lactobacillus gasseri.
