Antiplatelet and Antithrombotic Activities of <i>Lespedeza cuneata</i> via Pharmacological Inhibition of Integrin <i>α</i>IIb<i>β</i>3, MAPK, and PI3K/AKT Pathways and FeCl3-Induced Murine Thrombosis

<div>Effects of <i>L. cuneata</i> on agonist-induced platelet aggregation and changes in the platelet shape. (a) Agonists, such as collagen, ADP, and thrombin, were preincubated with washed platelets for 1 min in a light transmission aggregometer in the presence of 1 mM calcium chloride (CaCl<sub>2</sub>). This has been followed by stimulation for 5 min with constant stirring at 37°C using various agonists. <span class="nowrap"><svg height="13.532pt" id="M11" style="vertical-align:-3.4295pt"
