    In the epithelial cells of the proximal convolution of the striped snake kidney, the endoplasmic reticulum showing unusual arrangements was observed, which was so far found only in materials sacrificed during hibernation. In the plane of sections two types of profiles are observed; one is the quinque-petalous patterns, considered to be a cross section, and the other is the parallel lamellated structures, a longitudinal section. This endoplasmic reticulum has a close relationship with the small electron dense granules which are considered to be essential to its function, the chemical nature of which is unknown. Functional signigicane of this endoplasmic reticulum is indistinct at present, but it is easily supposed that this structure may represent the unusual cell activity during hibernation.

    Cilium-like fibers with internal tubular structures were found in the glandular and in the intercalary duct lumina of the toad pancreas. In the present study it was revealed that they are extraordinary long cilia originating from the basal corpuscle found in the apical cytoplasm of the centroacinar and the intercalary duct cells. However, the ultrastructural pattern and the number of inner tubuli contained in the matrix of the fibers were not completely clarified in the present study.

    1. The distribution and termination of nerve fibers in the mammalian and avian adrenal cortices was histologically investigated in sections treated with a modification of the Bielschowsky silver-impregnation method.
    2. Juxtacapsular ganglia were found in the monkey and dog. In the capsule of the adrenal gland, nerve cells were observed singly or in small groups. Scattered nerve cells were occasionally found in the zona fasiculata and the zona reticularis, too.
    3. In the capsule, many terminal formations of afferent nerve fibers were observed in the dog.
    4. Fine strands of the autonomic endformation made plexuses around the nests of cortical cells in all the cortical zones.
    5. Probably afferent nerve fibers were recognized to terminate in the cortical zones.
    6. The blood vessels in the cortex were innervated by probably afferent as well as efferent nerve fibers.
    7. In the adrenal gland of the fowl, fine nerve fibers were recognized to be distributed to the nests of cortical cells as well as to the blood vessels. Larger blood vessels were probably supplied with afferent fibers. Besides, complicated receptor formations were observed among the cortical cells.

    Histochemical observations on NADP-dependent dehydrogenases, glucose-6-phosphate and isocitrate dehydrogenases, in steroid producing tissues under physiological and pathological conditions were carried out. The enzymatic activities were confined to the internal thecal cell and corpus luteum in ovaries, adrenal cortex and chorionic villi of placentas. In tumors originated from these organs, the enzymatic activities were variable in tumor cells irrespective of endocrinological features. The localization patterns and stainabilities among NADP-dependent dehydrogenases and 3β-ol dehydrogenase, generally showed parallel relations except for a few exception.

    The fingerprint-like granules in the prostatic cancer tissue were observed elec-tronmicroscopically. The granules containing membranous structure were round in shape and measured 0.25-0.7μ in diameter. The granules are supposed to correspond to the lysosomal bodies of macrophage.

    In connection with a study of the aging process in thymolymphatic tissues (AWAYA and ODA 1965), it became disirable to have knowledge of the age changes in the human palatine tonsils. The purpose of the present study is to examine this subject.
    Eighty palatine tonsils with relatively slight or without any noteworthy lesions in the histopathological features, chosen from 165 patients performed on tonsillectomy under the diagnosis of the enlarged tonsil or chronic tonsillitis clinically, were used as material. They were divided into 8 groups by age: 4 to 5, 6 to 10, 11 to 15, 16 to 20, 21 to 25, 26 to 30, 31 to 40, and 41 to 49 years. Serial cross-sectional cuts, 6μ in thickness, were made from these tonsils after fixing in Zenker-formol and embedding in paraffin. The sections were stained with Meyer's acid hemalum and eosin.
    In this study, special attention was directed to the changes in the number and the percentage of the area of the secondary nodules in the organ. After measuring the area of the sections, the number of secondary nodules of different types occurring per 1cm2 of section was determined. As the author was able to confirm that in one extensively studied case the secondary nodules are distributed with great uniformity throughout the tonsil, the counting of the number of the secondary nodules was made of only 1 or 2 sections from each case. This method also provides for obtaining the percentage of the area of the secondary nodules. The secondary nodules of the Flemming types were classified into 3 types according to the cellular component consisting of the pale staining-center: (1) active, (2) half-active, and (3) inactive mature secondary nodules. If the pale centers are almost entirely composed of densely packed, medium-sized lymphocytes with many mitotic figures, they are termed “active”; otherwise they are called either “half-active” or “inactive”. The center of “inactive” type is composed mainly of reticular cells and devoid of mitotic figures of lymphocytes (Figs. 4-9).
    The main findings are shown in Tables 1 and 2, and Figures 1 to 3.
    The number of secondary nodules per unit area reached a maximum in the 16-20 age group, but the maximum numbers of the active and half-active forms, characterized by the active proliferations of lymphocytes, were attained in the 6 to 10 age group. The percentage of the area of the secondary nodules also reached in a maximum in the 4 to 10 age groups. As seen in Figures 1 and 2, the curve of the numbers of active and half-active forms then dropped sharply in the 11 to 1.5 age group and kept on at a low level during the succeeding periods studied. On the other hand, the curve of the number of the total secondary nodules including the non-active form and the percentage of their area showed a temporary fall in the 11 to 15 age group, the values again rising close to the maximum level in the 16 to 20 age group: thereafter the curves fell off markedly with increasing age.
    In addition, the amount of the lymphatic tissues other than the secondary nodules in this organ was observed to be largest in the 4 to 10 age groups and the number of lymphocytes appearing in the epithelium of the tonsils also largest in this period. These show that there is found some parallelism between the postnatal development and involution of the total tonsillar tissues and the aging process of the secondary nodules herein.
    Thus, the human palatine tonsils reach their maximal growth in the 4 to 10 age groups and thereafter undergo a slight involution which continues till about 20 years of age; beyond this age, this is followed by a more advanced involution. It is suggested that 11 and 21 years of age are the two critical times in the aging process of human palatine tonsils.

    The morphogenesis of the neuromuscular junction in the chick skeletal muscle was followed by the improved histochemical AChE method (KARNOVSKY and ROOTS, 1964; KARNOVSKY, 1964) and the silver impregnation method (SCHEFTHALER and MAYET, 1958). Specimens used were chick embryos from 5 to 21 days in ovo (the proximal portion of the lower limb), chicks 1 to 2 days ex ovo (M. sartorius) and adult fowls (M. sartorius and M. pectoralis major). A majority of the work was carried out by the light microscope, but a part of the enzymatic study was done with an electron microscope.
    Under the light microscope, the configuration of the enzymatically active structure became gradually more complicated in appearance and larger in size as the neuromuscular junction reaches maturity. The earliest appearance of the junctional AChE activity in the skeletal muscle was seen in embryos of as early as 7 days of incubation (stage 30) in the form of a single curved line, and afterwards the subsequent differentiation of the formed junction takes place. The morphogenesis of the neuromuscular junction in the chick skeletal muscle, studied enzymatically, could be divided into three main stages; the stage of initial formation (7 to 13 days in ovo), the stage of subsequent development (13 to 18 days in ovo) and the stage of nearly maturation which occurs at around 20 days of incubation.
    When observed under the electron microscope, the localization of the final product (copper ferrocyanide) of the AChE reaction was mainly in the synaptic cleft and the interspace between the axolemma and the plama membrane of the Schwann cell.
