Pathologic changes of mammillary body in clinical and experimental brain hemorrhage.

The histomorphologic changes of the mammillary bodies (MB) in 31 patients and 8 spontaneously hypertensive rats with brain hemorrhage were studied by light and electron microscopy. The results showed that the frequency of the ischemic change neurons in medial nucleus in MB is much higher than that in hippocampal CA1 section and multiplicated double-deck or multistratum basal lamina formed a network or branch pattern, which indicate that MB may be of important function.
