VCAM1 and hematocrit: Figure 7A–D illustrates that endothelin, P-selectin, VCAM-1, and ICAM-1 concentrations in heart homogenates of HT mice treated with PEG–AgNPs were significantly higher when compared with saline-treated HT group (p < 0.05) or PEG–AgNPs-treated normotensive group (p < 0.01–p < 0.05).
