Representative histological cross sections of coronary arteries 4 weeks after balloon injury (Verhoeff-van Gieson elastin stain, ×50). A: Control; B: Probucol; C: LXS; D: HXS. Disruption of the internal elastic lamina (←) was similar at the site of intimal reaction in all groups. Significant reduction of intimal hyperplasia was observed in groups treated with drugs, especially in HXS, compared with control.
