    1) The amplitude of the b-wave of the ERG in rabbits was found to increase following optic nerve section orr compression.
    2) After section of the optic nerve, either intracranial or intraorbital, the b-wave amplitude rose rapidly, up to the peak of 300-330% of the original amplitude, but hence decreased to 200-250% in 12 hours after the lesion of the optic nerve.
    3) After compression of the optic nerve, the rise of the b-wave amplitudc was slower. The peak value did not exceed the range of 180-250%, the subsequent drop being also less marked.
    4) The results showed no obvious difference whether the site of lesion orr the optic nerve was intracranial or intraorbital.
    5) The results of the present experiments are in line with those by Jacobsor et al., but not enough to justify their hypothesis.

    1) A subject who received all vitamins except a vitamin showed a delayed dark adaptation and after supplementation of the named vitamin he was able to bring his threshold value to normal.
    2) The difference of the visual threshold value before and after the vitamin supplementation can be seen as a measure of relative saturation of the body store as to the vitamin.

    In this paper, routine measuring methods of plasmin system and some limitations of these methods were described, and the importance of proteolytic activity of the euglobulin fraction without any activating procedure (latent activity) was emphasized as a tool of this enzyme study.

  • Histopathological Studies on Functional Zonation and Venous System of the Adrenals

    The adrenal glands of 141 cases with various liver diseases were histologically investigated with particular attention to the zona glomerulosa adulta (Sasano) and the adrenal venous system.
    Hyperplasia of the outer cortex, particularly of the adult glomerulosa was observed in chronic liver disease, mainly in liver cirrhosis, and. was prominent in the left adrenals. The findings are regarded as an expression of secondary aldosteronism. Dilatation and proliferation of capsular veins with dilatation of the cortical veins were also confirmed in chronic hepatitis, liver cirrhosis and hepatoma. Again, the findings were prominent on the left side. Medullary veins smaller than 0.4 mm in diameter had hypertrophied muscular walls. These suggest that the adrenal glands are involved in the collateral circulation in portal hypertension.
    The fasciculata was the main site of acute cortical injuries, which was prominent on the right side. The lesions are regarded to be induced not only indirectly by nonspecific stimulation via the pituitary gland, but also directly by local noxious influences from the diseased liver. In the anterior pituitary swelling and degranulation of S cells were found corresponding to acute injuries in the adrenal cortex. In chronic liver disease S cells were relatively well preserved and R cells were slightly increased in number. No pathognomonic lesions due to liver disease were found in the pituitary.

    With the aim of dynamically studying the water and electrolyte metabolism in vital body, heavy water, radiosodium and radiopotassium were used as tracers, chiefly in clinical tests. By use of such isotopes in combination with the current means of measurement, we enabled to measure the total body water, the extra- and the intracellular spaces, the total exchangeable sodium and potassium, the total sodium and potassium contents in the extra- and intracellular spaces and the sodium and the potassium concentrations in the extra- and intracellular fluids, and to draw inferences on the movement of these electrolytes in the body from a dynamic point of view. But since we found many points in our study awaiting further elucidation, we hope we can make another report on the subject in near future.

    Spectral response behavior of single units was investigated in the visual cortex of the unanesthetized macaque monkeys with test stimuli of 0.5° in visual angle.
    1. Cortical and optic radiation units were distinguished by the configuration of spikes and spontaneous discharge rate.
    2. “On” units responding to a narrow-band of the spectrum were designated as “chromatic” or C type units. Their response maxima were found in three selected regions of the spectrum, orange-red (600-640 mμ), green (520-540 mμ) and blue (460 mμ) respectively. Most units showed one or two submaxima besides the dominant peak in their spectral response curves.
    3. Some units responded to a certain limited region of the spectrum with “on” or “off”, but to another with “off” or “on”, thus changing discharge type depending on the wavelengths. These units were designated as “opponent” or O type units.
    4. Some units responded to the whole parts of the spectrum, but showed no clear-cut response maxima anywhere in the visible parts of the spectrum.
    5. Some “on-off” units and pure “off” units showed two response maxima towards both ends of the spectrum.
    6. Two kinds of units, A and B, relating to rod receptors were distinguished. The common feature of these units was that the sensitivity maximum was found at about 500 mμ The unit A had a large receptive field and gave “on-off” discharges. Its photosensitivity is low compared with that of B. The unit B was always linked with photopic units and worked in a range of low intensities in which the linked photopic unit was almost inactive. Its receptive field was very small as compared with that of A.
