SERPINH1 and hydrops fetalis: In the AngII model for HF, both 82–89 and 88–95 were effective in suppressing the deleterious effects of AngII on HW/BW ratio, ventricular function (IVRT, EF, FS), fibrosis (Col I and HSP47 levels), and microvascular leakage although in some cases 88–95 is somewhat more active.
