イトマキヒトデ体こうへの数種のステロイド投与と卵巣たんぱく質量との関係

Abstract

The relation between injection of various steroids into the coelom and ovarian protein amounts was examined by using growing ovaries in the starfish Asterina pectinifera. Steroids were injected daily for 16 days, with the concentration of 10-10 mol/g body weight. Significant increase of ovarian protein/g wet wt against control occurred only by injection of estrone (p<0.001). Total protein amounts of ovaries, when body weights of all animals were converted into 100g, increased significantly in estrone (p<0.001) and androstenedione (p<0.01). On the other hand, injection of progesterone appeared to depress the growth of ovary.
