Acute atherosis and diffuse lipid infiltration of the placental bed: A review of historical lipid studies.

abstract：:Use of cocaine during pregnancy is known to have harmful effects on the mother and her fetus. Currently available models describing the pathogenesis of these effects focus on the involvement of cocaine target systems, primarily the noradrenaline transporter, in the mother and the fetus. The placenta which lies between...
