    With aid of the immunohistoc h emical technique, enzyme protein of alkaline phosphatase was recognized in the cytoplasm of the goblet cell, in the material within the lumen which was supposed to be secreted from the goblet cells, and along the surface of the mucous epithelial cells. The distribution pattern of the enzyme protein was quite different from that of the enzymatic activity. The goblet cells, which are negative to the alkaline phosphatase reaction by the conventional histochemical method, may contain the inactive alkaline phosphatase or the presumptive precursor which may be turned into the active enzyme as soon as it is excreted into the intestinal lumen and comes into contact with some activator contained in the intestinal juice.
    Since the localization of the enzyme protein of alkaline phosphatase is unknown in the kidney, bone marrow and in the other tissues which have the positive enzyme, reaction, it is impossible to find the difference of the distribution pattern between the results obtained by histochemical and immunohistological methods. Therefore, the origin of the supply of alkaline phosphatase in the kidney and other tissues remains still unknown except the intestine as these tissues do not have the goblet cells.

    1. The M. transversus thoracis in both man and monkey arises from the rib in the area extending from the lateral tip of the costal cartilage to the bony rib, that is, from the rib or costal cartilage near costochondral joint, and inserts into the lateral edge of the sternum or xiphoid process.
    In man, however, there were instances in which this muscle arose from the intercostal space, that in which it inserted into the sternocostal joint, etc., so that depending upon the relation between the origin and insertion a classification into four types was possible. A further subdivision was possible according to whether the origin or insertion is by a single muscle or separated into two parts.
    2. The rib of origin in monkey ranges from the first to seventh rib, but the origin from the first rib was frequently absent. In man it was more limited both above and below, usually being from the second to sixth rib.
    3. This muscle in monkey was well developed so that at the insertion the muscular digitation united each other to form a triangular muscular sheet with the tip being the site of origin at the rib and the base being that of insertion into the sternum. In man, however, fusion at the i n sertion and thus the formation of a muscular sheet was found only for those muscles arising from the lower ribs.
    4. This muscle in man and monkey mostly crossed over one rib to occupy two intercostal spaces.
    5. The location of this muscle corresponds to the area in which the M. intercostalis internus is absent so that it appears to compensate the region where the M. intercostalis internus is absent.

    (1) In the early developm ental stage of the tooth germ, specific spindle cells and small globular substances appear in the enamel knot. In the human fetus it is only in the early cap stage that the spindle cells were observed in the vicinity of the enamel knot, while in the mouse embryo they are present not only in the early cap stage but also in the free end of the bud-shaped epithelial ingrowth.
    (2) The nuclei of the spindle cells were stained darkly with hematoxylin, while the nuclear shrinkage was hardly observable. The nuclei of the spindle cells were stained green or leek green or lacked the staining affinity with Mallory Heidenhain and Masson Goldner stains. With regard to Feulgen reaction and methyl-green pyronin stain, no specific features were recognized.
    (3) In the dental papilla some of irregular shaped mesenchymal cells had nuclei which showed almost the same hue as that of the spindle cells with the above stain methods.
    (4) In the early cap stage small globular substances were also observed in the enamel knot. They were stained brownish black or yellowish brown with hematoxylin and eosin stain, homogenously umber or drab darkly with Masson Goldner stain, and red brown or drab with Mallory. Heidenhain stain. They showed a positive Feulgen reaction. Therefore, they are not red blood cells, but probably represent product of cell death.

    Upon intraperitoneal injection of 4% EDTA solution to the rabbit, the author measured changes in serum calcium concentration after 30 minutes,1 hour,3 hours,6 hours,12 hours,24 hours and 48 hours respectively, and at the same time observed ultrastructural changes in the parathyroid gland with an electron microscope, thus obtained the following results.
    1) Serum calcium concentration was rapidly lowered immediately after administration of EDTA, reaching the lowest value in 30 minutes after injection, then gradually rose to the normal value in 6 to 12 hours after administration.
    2) In 30 minutes and 1 hour after administration of EDTA an aspect of secretory granules accumulated to the plasma membrane was observed.
    3) Accumulation of secretory granules to the plasma membrane means an aspect indicating release of secretion. There were granules of low electron density and vacuoles both with almost the same size as secretory granules together with the mature secretory granules. It can be considered as an aspect indicating diacrine secretion.
    4) An aspect of emiocytosis shown in the parathyroid gland of the normal rabbit could not be seen.
    5) In 6 hours to 24 hours after administration of EDTA an increase of well-developed granular endoplasmic reticula, ribosomes and mitochondria was indicating that protein synthesis was actively functioning, however, in the Golgi apparatus no active formation of secretory granule was seen.
