JOURNAL FREE ACCESSThe present investigation of e pithelium of the human gallbladder elucidates the following:
1. The epithelium consists of a single layer of columnar cells. The columnar cells are prismatic with 5 to 7 angles and measure 25to 32μ, in height and 3.5 to 7.0μ in width.10 C. Togari and T. Okada
2. The surface of the epithelial c e l l has terminal bars and a cuticular border which shows a clearly visible striation.
3. The epithelial cell contains a single n ucleus which is oval, rarely round and situated somewhat basally. The nucleus has moderate chromatin content with one to three nucleoli. No mitotic figures are seen in them.
4. Most of the mitochondria are rod-shaped or granular, and few filamentous.
5. The Golgi apparatus appears generally as a loose network of fibrils in a supranuclear location. In transverse section this apparatus is made up of a loop in the central zone of the cell body.
6. The epithelium has secretory capacity of mucu s -like substance. This substance is found as vacuoles formed in the Golgi apparatus and discharged from the cuticular border passing through the apical zone.
7. The epithelium has another capacity of absorbing fat. Some fat of bile are absorbed through the cuticular border and develo p to fat droplets in combination with granular mitochondria. These droplets appear often in the apical and basal zones and in the basal intercellular space.
8. G lycogen cannot be found in the epithelium.
9. Among epithelial cells the goblet c ell is not found, but the cask-like and crayon-like cells are seen.
10. The cask-like cells appear scattered singly or in groups among epithelial cells. They are short and thick and show a clear cell body without containing a large amount of vacuoles or fat. These cells seem to be in high absorption of water from bile.
11. The crayon-like cells appear also scatte r ed singly or in groups; they are slender and stain far darkly in both the nucleus and cell body. They seem to be of lowered function resulted from compression by adjacent cells.View full abstractDownload PDF (2431K) -

1) The change of liver ce l l protein of an osseous fish, Oryzias latipes, after starvation of ten days, of twenty days and of thirty days was observed cytochemically with Y a s um a-I c h i k a w a's ninhydrin-Schiff's reagent technique.
2) Protein i n hepatic cells increase gradually when starvation proceeds showing the highest value on the twentieth day, and on the thirtieth day the amount of protein decrease below the control value.
3) The amount of protein in nucleolus and mitochondria does not show any remarkable fluctuation, on the other hand, the surrounding cytoplasm and karyoplasm increases and decreases markedly.View full abstractDownload PDF (1103K) -

JOURNAL FREE ACCESS1. Three groups of indivi d u als of Oryzias latipes were kept for five hours in the water of the temperature 0°C.,31°-32°C. and 18°-20°C. respectively. The activity of alkaline and acid phosphatase in liver cells of these fish was observed.
2. Alkaline phosphatase:
In the low-temperature experiment, the activity is intensified in nucleolus and bile capillary, and is reduced in cytoplasm.
In the high-temperature experiment, the a c tivity is remarkably intensified in nucleus, in blood vessel wall, in portion of cytoplasm in contact with blbod vessel, and in bile capillary. Cytoplasm of hepatic cells contains vacuoles, in which no positive reaction is obse rvable, but around which strong activity is shown.
3. Acid phosphatase:
In the low-temperature experiment, the activity of the, nucleus is increased to some extent, while the reaction in cytoplasm and bil e capillary decreases.
In the high-temperature experiment the activity in nucleus is slightly intensified, but the activity in cytoplasm is diminished. Within cytoplasm, vacuoles exist, which show no positive reaction.View full abstractDownload PDF (617K) -

1. Polysaccharide and pro t ein in liver cells of Oryzias latipes, which were kept in the water of room temperature, of 0°C. and of 31-32°C., were examined.
2. Polysaccha r ide decreases to some extent in the low temperature experiment, and diminishes markedly in the high temperature experi ment.
3. In the low temperature experiment, a change of protein in nucleus is scarcely realized, whereas the amount of protein in cytoplasm decreases.
In the high temperature experiment, the amount of protein increases in nucleus and decreases in cytoplasm.View full abstractDownload PDF (719K) -
