electron microscopic examination of the effect of linoleic acid hydroperoxide on cultured smooth muscle cells from human umbilical artery revealed that incubation of the cells with 5.0 nmol/ml ( in terms of malondialdehyde ) of the hydroperoxide for 3 h caused a decrease in the electron density of the mitochondrial matrix and that dilatation of the rough-surfaced endoplasmic reticulum occurred when the cells were incubated with 10 nmol/ml of the hydroperoxide .
