Eclampsia is a condition occurring in pregnant women that clinically seems closely allied to uremia, although it may be present without any albuminuria. When death takes place the liver will show congestion, capillary thrombosis, anemic and hemorrhagic necroses, and thrombosis. The kidney will present a nephritis ranging from a slight parenchymatous degeneration to an acute, intense nephritis. It is claimed by some that eclampsia is due to a deficient oxidizing capacity on the part of the liver which fails to convert protein derivatives into urea. There are others who believe that the toxic substances are probably derived from the fetus or the placenta.
