NEW INDEX, “BASIC AMOUNT” OF WEIGHT, WATER AND COMPOSITION OF THE BODY AND SIMPLE CALCULATION OF STANDARD WEIGHT FOR HEIGHTSEIICHI ASANO, SHUN MATSUKI, EIICHI KATO, KIKUO MARUMO, SHOKICHI YAMAZ ...1962 Volume 11 Issue 4 Pages 211-221

JOURNAL FREE ACCESSThe expressions of body weight, body water and composition of the body which serve as the bases in study of metabolism and treatment of diseases have been discussed and we came to the following conclusions.
(1) The factors that give influences on body weight were discussed and it was emphasized that in the comparison of nutrition and hydration the factor of height should be excluded. The weight per unit height was still inadequate.
(2) In order to solve the difficulties, a new index, “basic amount” of body weight which was free from the factor of height was presented. As it varies with changes of nutrition and hydration, it would be able to compare nutrition or hydration by this index and an equation has been presented to cal-culate easily the standard body weight from the height.
(3) It was also pointed out that the expression of absolute value and per-cent body weight of water and composition of the body are sometimes irrational. In order to correct these points, a new index, “basic amount” of water and com-position of the body is adequate. With this index, it became possible to compare body water or body composition in subjects with different heights and weights.
The outline of this study was reported at the 57th annual meeting of the Japanese Society of Internal Medicine on April, 1960.View full abstractDownload PDF (545K) -

II. STUDIES ON TRICHOMONAS MURISMAKOTO OSADA1962 Volume 11 Issue 4 Pages 227-252
Published: 1962
Released on J-STAGE: March 27, 2009
JOURNAL FREE ACCESSUltrastructures of organellae of Trichomonas muris elucidate by the current studies were as follows:
1) Axostyle. This is a roll made of a membrane having transverse stria-tions. This roll has a logitudinal seam where the brims of the membrane are overlapped at the posterior part of the axostyle. This membrane or the wall of the axostyle is unrolled gradually as it approches to the nucleus at which level, it is completely opened to make a concavity like a spoon. It extends further upwards to the anterior proximity of the cell making another shallower concavity anterior to the nucleus. It is curved spirally a little and anticlockwise when seen from the top. The posterior part of the axostyle curves opposite to the costa.
2) Costa. The costa has a comb-like structure with transvers striations of clear and dark zones. It looks like to be fairly stiff and may serve as a supporting structure of the body. The undulating membrane is connected with this organelle by minute fibrils. These aspects also suggest the possibility of the costa to support the fixation of the undulating membrane.
3) Undulating membrane. This is consisted of posterior flagellum, un-dulating membrane proper and a membrane enveloping these structures. The undulating membrane proper is composed of lamellae arranged transversely to the long axis of the membrane. These lamellae are tightly contact each other and connected to the costa with minute fibrils as stated above.
4) The parabasal body. This is a structure similar to Golgi apparatus and is connected to the base of the costa with a ribbon-like structure, the parabasal filament.
5) Cabbage-like bodies. These are found in the protoplasm. Their nature and function were not elucidated.
6) Ultrastructures of flagella are the quite same with those of other animals. It may be characteristic that at the base of flagellum there are several electron-dense minute granules.
7) Hook-shaped bodies, six in number, are seen near the anterior end of the body, having one leg putting on the inner surface of the axostyle. These bodies may be connecting flagella and costa to the axostyle.
8) Nuclear cloud around the nucleus and chromatic rings arround the axostyle have the same structure and are actually the endoplasmic reticulum.View full abstractDownload PDF (30097K) -
PATHOLOGICAL STUDIES ON THE PROSTATE GLANDS OF JAPANESE, WITH SPECIAL REFERENCE TO LATENT MALIGNANCYHIROSHI TAZAKI1962 Volume 11 Issue 4 Pages 253-278

JOURNAL FREE ACCESSTwo hundred fifty four prostate glands in Japanese over 30 years of age were pathologically studied in unselected autopsy cases.
The following results were obtained:
1) After a screening of the large number of sections of the glands, 125 foci recognized as the characteristic lesions were histologically analyzed in details by two dimensions, that is, epithelial pattern and stromal invasion. These foci revealed a wide range from a low to a high degree of atypism and were divided into three groups.
2) Age incidence, size, number localization and histological patterns of the foci were described respectively on each groups.
3) Group 1 included four cases of primary prostatic carcinoma (true latent carcinoma). They were found with an incidence of 2.4 per cent out of 170 cases of men over 50 years of age.
4) The foci divided into Group 2 revealed an incidence of 13.5 per cent out of men over 50 years of age. They showed varied degrees of cellular atypism and invasion. Although some of them showed atypism similar to that in Group 1, they were interpreted as a transitional stage to the latent prostatic carcinoma and also might be called “precancer” in microscopical analysis of the present series.
5) In group 2 the “elastosis” was recognized in the surrounding tissues of proliferating glands, especially with the close relation to epithelial cells. The significance of the elastosis is briefly discussed with the concept of “tissue induction.”
6) Group 3 consisted of glands with senile atrophic changes, atypical pro-liferation in nodular hyperplasia and inflammatory process. There were neither malignant growths nor the possibility of misinterpreting foci.
