  1. Incubation time of VSMC with various agents, 4 hours. The difference between lyso PtdCho + linoleic acid and lyso PtdCho alone, p = .011, and with linoleic acid alone, p = .012. The difference between lyso PtdChol + oleic acid and lyso PtdCho alone, p = .003, and with oleic acid alone, p = .003.
