Exacerbation of Thrombotic Responses to Silver Nanoparticles in Hypertensive Mouse Model

Figure 4

In vitro platelet aggregation in whole blood collected from normotensive (NT) or hypertensive (HT) mice after intratracheal (i.t.) instillation of saline or polyethylene glycol silver nanoparticles (PEG-AgNPs). Blood samples obtained from the aforementioned groups were incubated at 37°C with ADP (0.1 μM) for 3 min and stirred for another 3 min, and single platelets were then counted. The degree of platelet aggregation in HT or NT mice exposed to PEG-AgNPs or saline was compared with each other and with that obtained in untreated (without ADP) whole blood obtained from control (unexposed) mice. Data are the (). Statistical analysis by one-way ANOVA followed by Holm-Sidak’s multiple comparison test.
