Electro-microscopic observations of liver lesions after intravenous inoculation of mouldy hay extracts.

With the aid of the electron microscope, a number of histopathological changes in the liver of mice caused by mycotoxins from mouldy hay were examined and studied. These changes were observed in the mitochondria, the cell nucleus, and the cell membranes, and included fatty and parenchymal degeneration, plasma granulation, vacuolisation and vesiculation, glycogen secretion, incorporation into RNA, karyolysis and karyolaxis, and space of Disse constriction.
