第3編 ローゼンミユラー氏窩の組織学的研究

抄録

Comparative histological observations were carried out on lymphoid tissue of Rosenmüller's fossa in the order of ages, and also the relationship between the thickening of the capsule of lymphoid tissue in R. Fossa and the hypertrophy of lymphoid tissues was studied.
The maximum development of lymphoid tissues is reached at the age of four, and the size and number of lymph follicles are also greatest at four, and both the size and number decrease progressively in the order of 2 years and six months, 14 years old, 26 years, and one full year old. In older children and adults some show large retention cysts and multiple cysts; and certain ones clearly indicate that these malformations are caused by the dilatation of the excretory duct of lymphatic glands. Moreover, there are some revealing big adhesions bridging across the anterior and posterior walls of R. fossa.
It is believed that the hypertrophy of lymphoid tissues in R. Fossa, big adhesions and formation of cysts as observed in adults impede the backward and upward movement of Torus tubaris and these constitute the cause of tubal stenosis.
