After an intraperitoneal injection of diluted yolk in female quails, young chicks or chick embryos (killed with minimal loss of blood), the absorption of a considerable quantity of yolk granules by the ovarian medullary lacunae can be demonstrated. This can be confirmed by the i.p. injection of killed Hela cells. From our investigation it may be concluded that the avian ovary, by the progressive expansion of its medullary lacunae, develops into a contractile sac-like structure with small openings (communicating with the peritoneal cavity) on its dorsal side. The lacunar system seems to function as an expansion room for the enlarging follicles (also the large pediculated follicles) and intervenes in follicle stalk formation. The relatively rapid uptake by means of an ovarian pumping mechanism of particles and fluid from the peritoneal cavity into the lacunae, suggests also that the latter play a role as diffusion chambers in the supply of nutritious substances to and elimination of wastes from the follicles.
在向雌性鹌鹑、雏鸡或鸡胚（以最少失血方式处死）腹腔注射稀释的卵黄后，可以证明卵巢髓质腔隙吸收了大量卵黄颗粒。腹腔注射灭活的海拉细胞可证实这一点。从我们的研究中可以得出结论，鸟类卵巢通过其髓质腔隙的逐渐扩张，发育成一个收缩性的囊状结构，其背侧有小开口（与腹膜腔相通）。腔隙系统似乎起到了为不断增大的卵泡（包括大的有蒂卵泡）提供扩展空间的作用，并参与卵泡柄的形成。通过卵巢泵吸机制，颗粒和液体从腹膜腔相对快速地被吸收进入腔隙，这也表明腔隙在向卵泡供应营养物质和从卵泡清除废物方面起到了扩散室的作用。
