JOURNAL FREE ACCESSIn the substantia corneae in the human adult there are seen nerve elements, which are mostly composed of fine vegetative, but partly of thick sensory fibres.
Also in the cornea the termination of the vegetative fibres are repre-sented as the terminalreticulum, as Reiser pointed out. The development of this terminalreticulum is very strong. It distributes widely in the sub-stantia and innervate the corneal cells not only by contact, but also through their protoplasm. Then it might be thought that the lymph stream in the fluid canaliculi will be regulated by this terminalreticulum, as it is so in the blood capillaries.
Against Reiser's report, the terminalreticulum does not enter the epithelium.
The terminations of the sensory nerve fibres in the cornea are not the corpusclar endings described by many authorities. They are seen mostly in the anterior part of the substantia propria especially in its cir-cumference and divided into two kinds of the non-ramified and the rami-fied, which terminate chiefly sharply. Besides, they enter often the epi-thelium and pass into the intraepithelial fibres.
The intraepithelial fibres originate, however, generally in the plexus infraepithelialis, which is formed under the epithelium. They are repre-sented as relatively thick independent fibres, run forward not only between the epithelial cells, but also through their cell bodies and terminate finally with their free sharp end.View full abstractDownload PDF (3967K) -

JOURNAL FREE ACCESSWe arrange a tube focus and rotation axis of two rotation-tables A and B in one plane and make the central X-ray incline to the table of the rotation-table B fifteen degrees. We place the body on the rotation-table A. And on the rotation-table B we place a film-block. Irradiating the X-ray, we rotate the two rotation tables synchron from 0 degree to 360 degrees. Then on the film-block on rotation-table B we get the three dimensional X-ray image similar to the actual body on the rotation table A.
We proved this not only. theoretically, but also experimentally.
We named this method of getting the three dimensional X-ray image “the solidography.”View full abstractDownload PDF (2213K) -

JOURNAL FREE ACCESSThe sensory terminations in clitoris in adult show remarkable develop-ment, compared with those in the embryo of 10th month, but with a exception of the intraepithelial fibres which exist no more even in the common epithelium remained in the radix clitoridis.
Such a special corpusclar termination as having a swelling inner bulb in the embryo seems to beloiig to a Pacinian corpuscle, because it show in adult in its periphery the formation of some of lamellae.
The corpusclar terminations except the Pacinian corpuscles in the external genitals in adult have long included Krause's end bulbs, Krause's genital bodies and Meissner's tactile bodies. But there is no essential difference between both of the formers. And the existence of the latters is denied too. The morphological difference of these bodies consists in the conditions of the arrangement of the sensory nerve fibres and special nuclei in the inner bulb.
These terminal bodies are divided into 3 types. But, as they have morphologically more or less similarities, they should be called collectively the genital nerve bodies.
Each termination of the type 1 and 2 has remarkable inner bulb, which is showed as a synchytium consisting of fine granular substance and special nuclei and considered to be of peripheral glia and of endocrine nature.
The terminal bodies of the type 1 are characteristic with the glornerular arrangement of the nerve fibres extending widely in the whole territorium of the inner bulb, while the type 2 with the nerve distribution mainly in the center part of the inner bulb.
The terminations of the type 3, which have no formation of the inner bulb and could be called the special ramified terminations too, are seen in general in the strong connective tissue, for example in the tunica albuginea of corpora cavernosa clitoridis. The thick medullated fibre loses its myelin just before the terminal formation and divides into many branches, which terminate with the. arrangement as seen in the type 2.View full abstractDownload PDF (5979K) -

JOURNAL FREE ACCESSIn ganglion semilunare and ganglion nodosum exist 2 kinds of sensory terminations originated in the collaterals of the nerve processes of their ganglion cells. Those of the type 1 are found in the neighbourhood or the surroundings of the ganglion cells and plexus- or basket-like in form, while those of the type 2 are seen among the ganglion cells and represented as the glomerular terminations ending in the gathering body of the special cells. Their physiological significance is worth serious consideration.View full abstractDownload PDF (2316K) -

XI. Further Contribution on the Pigment-bearing Cells in Mongolian Spot and Blue NevusMinor Ito1951 Volume 54 Issue 2 Pages 181-187
Published: June 25, 1951
Released on J-STAGE: November 28, 2008
JOURNAL FREE ACCESSI confirm that the pigment-bearing cell of blue nevus corresponds histologically to the endo- or perineurium of mesoderal nature, There-fore I guess that the Mongolian spot cell originates from the same origin of blue nevus and that it is the mesodermal melanoblast which corresponds to Weidenreich's so-called perineurale Pigmenthülle.
And I agree to the polymeric inheritance theory of Mongolian spot according to the physiologic-genetical considerations.
N. B. In my previous report I used the term “chromatophore” but I revise this in present treatise and advocate the “Pigment-bearing cell” in order to avoid the liability of misunderstanding because in the strict sense “chromato-phore” has merely the ability of phagocytosis of pigment,View full abstractDownload PDF (410K) -

JOURNAL FREE ACCESSThe eye was illuminated by white light for 2 seconds, and then the electrical excitability of the eye was measured by applying electrical square pulses of varying frequencies to the eye for 0.5 seconds. Percentage increases in electrical excitability were denoted by ζ and plotted as ordinates against the time after the end of pre-illumination.
1. ζ-time curves thus obtained were compared with those deter-mined by a single pulse of 0.1 second, using colored lights for pre-illumina-tion. It was found that changes in frequency of stimulating currents have the same effect as color changes of pre-illuminating lights upon the shape of ζ-time curves.
2. When red light was used for pre-illumination ζ-time curves showed a maximum at 1 second, irrespective of frequencies of stimulating currents. ζ-frequency curves showed a maximum at 55 cps. Since red light of such extremely long wave-lengths as used in this experiment excites red receptors only and causes the supernormal electrical excitability of this kind of receptor, the ζ-frequency curve having a maximum at 55 cps. represents a resonance curve of the red receptors. Resonance curves for green and blue receptors determined in a similar way showed a maximum at 42 and 36 cps. respectively.
3. Rods were selectively excited by exposing the extreme periphery of the retina or by using very weak light below color-threshold for pre-illumination. The ζ-values thus obtained were plotted against the fre-quencies of stimulating currents. The curve so obtained represents a resonance curve of rods, and shows a definite maximum at 20 cps.
4. The relation between the minima of strength-frequency curves obtained by Motokawa and by Abe and the resonance frequencies deter. mined in the present experiments was discussed.View full abstractDownload PDF (356K) -
