We have previously demonstrated that pressure application of the protein kinase C (PKC) activator phorbol 12-myristate 13-acetate (PMA) onto some neurons in the anterior hypothalamic area of rats increases neural activity in vivo and that this PKC activation-induced increase of neural activity is enhanced in spontaneously hypertensive rats (SHR), an animal(More)
A small number of differentiated tumor cells could be found besides a great number of undifferentiated ones. Abnormal dense granules were found in the nuclei of un-differentiated tumor cells, not in differentiated ones. Non-specific filaments were seen in the cytoplasm of undifferentiated tumor cells. Differentiated tumor cells demonstrated various stages(More)
The effect of certain factors on the early postnatal development of the retina was studied by electron microscopy. Although the retina of developing rats injected with sodium iodate on the 1st and 7th postnatal days showed no retardation of development of photoreceptor outer segment, it began to degenerate about 3 weeks after birth. The retina of developing(More)
