For the demonstration of glycogen, eggs and embryos were treated with the periodic acid-Schiff with or without a preceding salivary test. The activity of α-GDH was demonstrated by the method of BARKA and ANDERSON. The amount of glycogen granules was abundant in 1-cell eggs at the germinal vesicle, unfertilized and sperm-penetrated stages, and in embryos from the 2-cell to expanded blastocyst stages, but less in hatched blastocysts. The activity ofα-GDH was moderate in eggs and embryos at the stages from 1-cell to expanded blastocyst, but weak in hatched blastocysts.}, pages = {37--42}, title = {培養したウシの卵子と初期胚におけるグリコゲン穎粒の組織化学的観察}, volume = {48}, year = {1996} }
