ジャーナル フリーGrowth hormone (GH) cells in the adenohypophysis of adult female mice of the C3H/He strain, with a high incidence of mammary tumors, and of the C57BL/6 strain, with a low incidence of such tumors, were compared by stereological morphometry with electron microscopy. There was no significant difference in the population of GH cells between the two strains of mice. The size of GH cells was significantly larger in the C3H/He mice (<0.01). In ultrastructural observations by electron microscopy, GH cells in the C3H/He mice contained more secretory granules and better-developed cell organelles than those in the C57BL/6 mice. The body weight was significantly greater in the C3H/He strain than in the C57BL/6 one (P<0.001). These results suggested that GH cells in the C3H/He mice may have higher GH synthetic activity than those in the C57BL/6 strain.抄録全体を表示PDF形式でダウンロード (4086K) -

ジャーナル フリーThe fiber arrangement of the canine tympanic membrane was examined in 13 dogs by scanning electron microscopy. Especially, in the pars tensa of the tympanic membrane, the connective tissue layer was composed of outer radial and inner circular fibers. It had a most interesting straw rope-like framework of fiber arrangement.抄録全体を表示PDF形式でダウンロード (2386K) -

ジャーナル フリーWe performed histological and histochemical investigations on the so-called cardiac and fundic glands in the swine, to clarify the characteristics of these glands.
1. Glands, distributed in the immediate vicinity of the proventriculus, are regarded as cardiac glands, and are apparently different from the fundic glands.
2 Immature chief cells in the fundic glands lose their PAS-positive substance and differentiate into mature chief cells, which form a well-developed reticulate framework in the supranuclear cytoplasm. However, these changes are not observed in the cardiac glands.
3. Fairly small, claret pepsinogen granules are contained in the fundic gland mucous neck cells and immature chief cells. The same granules in fundic gland mature chief cells are coarse and dark blue.
4. The cardiac glands also contain many small, claret pepsinogen granules.
5. We speculate that the PAS-positive chief cells with no reticulate framework and containing small, claret pepsinogen granules are in the undifferentiated stage.
6. Based on the above facts, the so-called cardiac glands are considered to be undifferentiated fundic glands. That is the cardiac glands do not exist in the swine.
7. Weak and strong acid mucopolysaccharide are found in the upper portion of the cardiac glands and neutral mucopolysaccharide are found throughout the cardiac glands. However, the cardiac glands of the swine are not simple mucous glands; their main function is to secrete pepsin.抄録全体を表示PDF形式でダウンロード (7642K) -

ジャーナル フリーThe present report describes an anomalous case of the risorius arising from the masseter tendon of an 83-year-old Japanese male used for student dissection practice. In this case, the risorius appeared to be almost of the typical type. However, one part of the risorius arose not from the fascia or skin over the masseter but directly from the masseter tendon itself. Such a situation is considered rare, since only one similar case has been reported by Eisler (1912).抄録全体を表示PDF形式でダウンロード (3608K) -

ジャーナル フリーAging based on body weight and longevity was studied in 102 male and 72 female mice. The mean longevity and the last decile survival age were 73.8 and 112.3 weeks in males and 84.7 and 129.2 weeks in females, respectively. Females showed significantly greater values for longevity and also survival frequency in the 50th to 120th week than males. The old age phase after the 60th week seemed to be divided further into two phases, an early and a late phase, around the 100th to the 110th week. In four groups classified by longevity, there are few differences in the pattern and the mean body weight at each age between three of the groups, except for the LO (longest lived) group. The latter group was lighter than the others in the young adult phase (stage VII)抄録全体を表示PDF形式でダウンロード (1353K)
