abstract
鳥類卵の卵外皮形成機構を明らかにする目的で,ウズラ卵管の峡部,峡子宮部,子宮部,および脱灰したウズラ卵卵外皮の組織学研究を行なった.

1. 峡子宮部には固有の粘液細胞が存在する.本細胞には脂蛋白が濃密に存在する.
2. ウズラ卵卵外皮はニワトリのそれと類似の層形成ならびに各層の構造を有する.卵殻乳頭は中心核と周辺部とに分けられる.
3. 中性粘液多糖類が卵殼膜,卵殼乳頭中心核,クチクラに,酸性粘液多糖類が卵殼乳頭,卵殼乳頭,卵殼基質にみとめられる.
4. 卵殼乳頭中心核には脂蛋白も豊富である.
5. 既報および本論文の成績に基づいて,卵管の分必物と卵外皮構成物質との相互関係を検討した.
abstract
To clarify the formation of egg-coverings in birds, the isthmus, isthmouterine region and uterus of quail oviducts and their egg-coverings were investigated histologically. The obtained results are as follows.

1. Mucous cells proper to the isthmouterine region are termed as isthmouterine mucous cells. Their features are different from the isthmal and uterine mucous cells. The isthmouterine mucous cells are characterized by high stainability for lipoprotein reaction.
2. Stratification of decalcified quail egg-coverings and structures of each layer of them are similar to those of hen's eggs. The mammilla is divided into central core and superficial portion.
3. Neutral mucopolysaccharides are present in the shell membranes, central core of the mammilla and cuticle; acid mucopolysaccharides in the superficial portion of the mammilla and shell matrix.
4. The central core contains a certain amount of concentrated lipoprotein.
5. The author discussed the interelationship between the oviducal secretions and the constituents of the egg-coverings, on the basis of findings reported in previous and present papers.
