摘要：同腹のWistar系ラット16例を用い, 骨格筋線維の発達におよぼす性ホルモンの影響を組織学的に検討し, つぎのことが明らかになった. (1)体重の増加する割合は, 雄の去勢群では, 雄の対照群に比べて低下し, 雄の去勢+Ovahormon投与群では, その傾向は著明であった. (2)下肢筋の各筋重量の増加する割合は, 雄の去勢群では, 雄の対照群に比べて低下し, 雄の去勢+Ovahormon投与群では, その傾向は著るしかった. (3)M. tibialis ant. の全横断面積は, 雄の去勢群では雄の対照群に比べて, 赤筋線維5.1%, 中間筋線維8.8%, 白筋線維3.6%の低下を示し, 雄の去勢+Ovahormon投与群では, それぞれ20.3%, 25.0%, 29.0%の低下を示した. (4)M. tibialis ant. の筋線維一本あたりの平均横断面積は, 雄の去勢群, 雄の去勢+Ovahormon投与群とも, 赤筋線維, 中間筋線維および白筋線維において, 全横断面積の場合と同じ傾向を示した.
其他摘要：The purpose of this study was to inquire histologically the effect of sexual hormones on the development of skeletal muscle fibers making a distinction among red muscle fibers, medium muscle fibers and white muscle fibers. The experimental animals, Wistar-strain rats of the same venter, were divided into the following four groups on 21 days after birth: (1) Control group of males (2) Castration group of males (3) Injection group of Ovahormon (Benzoate Suspension 1000 Unit) into the male castration (4) Control group of female. The 0.2 ml of Ovahormon was injected into the third group on every other day. M. tibialis ant. of each group was removed on 70 days after birth and the histological method, using Sudan black B, was adopted in this experiment. The results obtained were as follows: (1) Rate of increasing of rats' body weight in the castration group of males was smaller than that in the control group of males and the tendency of that in the injection group of Ovahormon into the male castration was smallest among the four groups. (2) Rate of increase in muscle weight of rats' lower limbs (M. tibialis ant., M. gastrocnemius, M. soleus, M. plantalis and M. ext. digi. longus) showed the same tendency as that of body weight. (3) The decreasing rate of the entire cross sectional area of M. tibialis ant. in the castration group of male was 5.1% in red muscle fibers, 8.8% in medium muscle fibers and 3.6% in white muscle fibers. In the injection group of Ovahormon into the male castration each respective value of those was 20.3%, 25.8% and 29.0%. (4) The decreasing rate of the average cross sectional area per fiber in the castration group of males and the injection group of Ovahormon into the male castration showed the same tendency as that of the entire cross sectional area in red, medium and white muscle fibers.
