다국어 초록 (Multilingual Abstract)

This study deals with the transplantation of fertilized ova in the rabbits. Eighty four adult Japanese White rabbits(female 74 and male 10), weighing about 2.0㎏, were fed previously for a month and used in these studies. They were treated with P.M.S.(200-250 I.U.), H.C.G.(200-250 I.U.), Estrogen(2,000 I.U.) and Progestrone(10㎎ per day). And I observed and operated them. The results were as follows. 1. The rabbits treated with 1st method; Fifty four ova(at the 16- and 32-cell stages) were transplanted to three recipients at 30 min. after recovery. All of them were pregnant, but they were absorbed. 2. The rabbits treated with 2nd method; Fifty one ova(at the 16- and 32-cell stages) were transplanted, at 30 minutes after recovery, to four recipients. All of them were not pregnant. 3. The rabbits treated with the 3rd method; Twenty three ova(at the 16-and 32-cell stages) were transplanted into three recipients. All of them were not pergnant. 4. The rabbits treated with the 4th method; Thirty five ova(at the 8-, 16- and 32-cellstages) were transplanted into four recipients. All of them were not pregnant. 5. The rabbits treated with the 5th method; Three hundreds and sixty nine ova(at the 16-and 32-cell stages and morula) were transplanted into thirteen recipients. Seven rabbits resulted in successful production of 38 normal descendants. 6. The rabbits treated with the 6th method; Nighty eight ova(at the 8- and 16-cell stages) were transplanted into seven recipients. Two rabbits out of them were pregnancy, but they were absorbed early. 7. The rabbits treated with 7th method; Twenty eight ova(at 8-, 16-and 32-cell stages and morula) were transplanted into three recipients. One rabbit out of them was pregnant, but it was absorbed. The best treatment in this experiment was the 5th method.
