Fine Structure of Autonomic Ganglion in the Chicken Pancreas

Electron Microscopic Study on the Testicular Interstitial Cells in the Mouse

“…This distribution agreed with that in the perikaryon of neurons (KUDO, 1971;ONA, 1974;YAMAMOTO, 1977) and might probably be caused by an extensive network formation of Golgi elements in the cytoplasm. Although several authors have described a paranuclear location of the Golgi complex (CHRISTENSEN and FAWCETT, 1961;LEESON, 1963;YAMA-DA, 1965;DE KRETSER, 1967a) they might have incidentally observed one of the several Golgi areas which was juxtanuclearly located as pointed out by SINHA and SEAL (1969), CHRISTENSEN (1975) and USUI (1976).…”

An Electron Microscopic Study of the Olfactory Mucosa in the Bat and Rabbit

“…Nissl substance confined to perikaryons of bat and rabbit olfactory neurons shows characteristic fine structural features as observed in ordinary neurons (AKIYAMA, 1960;EKHOLM and HYDEN, 1965;KUDO, 1971;ONA, 1974); it consists of as is widely known, flattened cisternae of rough endoplasmic reticulum and free ribosomes (polysomes), but the amount of ribosomes attached to membranes of endoplasmic reticulum is relatively small in contrast to the large amount of free ribosomes distributed among the flattened cisternae of rough endoplasmic reticulum, which frequently show the so-called lamellar patterns.…”

“…Recently KUDO (1971) reported the large dense cored vesicles in his electron microscopic study on the autonomic ganglion in the chicken pancreas and attempted a detailed discussion on this subject. Dendrites, however, are free of the vesicles in question.…”

The terminal autonomie nervous system in the pancreas of newts. Electron microscopic investigations using acetylcholinesterase and zinc iodide-osmium tetroxide reactions

“…In this sense the la& of Cajal interstitial cells or of ganglionary ones, frequently met with in the avian and mammalian pancreas (Coupland, 1958;Cornline et al, 1963;Kudo, 1971;Trandaburu, 1972 a;a.o. ), seems to represent, perhaps except for several species of fishes (Watari, 1972) and anurans (Lawzewitscb, 1970;Trandaburu, 1972 b), a common feature of poikilothermic vertebrates.…”

“…Among the numerous ultrastructural studies dealing with interneuronal synapses in various organs, there are comparatively few which describe axo-axonaI synapses (Colborn and Adarno, 1969;Ehinger et al, 1970). Synapses of this type without specialized structures at their level were detected in the pancreas of frogs (Trandaburu, 1972 b) and suggested in that of chicken (Kudo, 1971). As regards the axolemma specializations, according to Ehinger et al (1970), they are not prerequisite, at least in peripheral tissue, for the nervous impulse transmission.…”
