The study was carried out to investigate the effects of morphology, reproductive cycle, incubation time and activation of oocytes on in vitro maturation of cat oocytes and development of IVM/IVF embryos. The results were summarized as follows: 1. When recovered from ovaries collected at different stages of the reproductive cycle (inactive, follicular and luteal stage), the developmental rates of oocytes to GV and MI stage were 72.5% and 27.5%, 57.5% and 7.5%, 62.5% and 17.5%, respectively. 2. The developmental rates of oocytes with cumulus cells to GV and MI stage in different conditions of incubation (5% CO₂, 95% O₂ and 10% CO₂, 90% O₂) were 70.0% and 27.5%, 52.5% and 20.0%, 55.0% and 12.5%, respectively. 3. The developmental rates to GV and MI oocytes when cultured at different time of incubation (17∼20, 21∼24, 25∼28 and 29∼32 h) were 67.5% and 20.0%, 67.5% and 30.0%, 62.5% and 22.5%, 65.0% and 15.0%, respectively. 4. The fertilization and cleavage rates of freshly collected oocytes with and without cumulus cells were 72.5% and 25.0%, 37.5% and 7.5%, respectively. The rates were greater in oocytes with cumulus cells than those without cumulus cells. 5. The fertilization and cleavage rates of oocytes recovered from ovaries collected at different stages of the reproductive cycle (inactive, follicular and luteal stage) were 75.0% and 25.0%, 40.0% and 7.5%, 50.0% and 15.0%, respectively.

본 연구는 소형 고양이의 불임 해결과 체외수정란을 생산하기 위한 방안으로서 난자의 형태, 번식주기, 배양시간 및 활성화 처리가 난포란의 체외수정 및 체외발생에 미치는 영향을 조사하였다. 1. 신선 및 salt에 보존한 난소로부터 회수한 난구세포부착 및 나화 난자를 각각 배양했을때 체외수정율 및 분할율은 65.7%와 17.1%, 28.6%와 8.6% 및 57.1%와 13.3%, 23.3%와 3.3%로서 난구세포 부착 신선난자가 나화 난자에 비해 높은 체외

본 연구는 고양이의 불임 해결을 위한 방안의 하나로써 체외수정란을 생산할 목적으로 난자의 형태, 보존 및 번식주기별 난자의 체외발생에 미치는 영향을 조사하였다. 1. 신선 난소로부터 회수한 난구세포부착 및 나화 난자를 각각 배양했을 때 GV 및 MI으로의 체외성숙율은 74.3%와 25.7%와 및 28.6%와 11.4%,로써 난구세포 부착 난자가 나화 난자의 비해 높은 체외성숙율을 나타냈다. 2. 휴지기, 난포기 및 황체기 단계로 구분하여 채취한 난구세포

This paper intends to reveal that Eliot’s life has a good influence on his poems, especially appearing in Old Possum’s Book of Practical Cats which was published in 1939. But a version of it was announced by Faber and Faber, as “Mr. Eliot’s Book of Pollicle Dogs and Jellicle Cats as Recited to him by the Man in White Spats,’ in the spring of 1936. Therefore we need to feel out the period from before and between 1936 to 1939, when Eliot suffered fromdomestic problems ashe tried to divorce his wife Vivienne, and Vivienne herself was confined to the mental hospital Northumberland House in 1938. So this paper deals with his personal experiences (or situations and accidents) happening through his unhappy marriage, especially the emotional conflicts between him and his wife Vivienne in Old Possum’s Book of Practical Cats.

T. S. Eliot has been known as a poet and critic for being so serious and moralistic that he might teach his readers. Yet, he published Old Possum’s Book of Practical Cats in 1939 for children, especially for his friends. In this sense, this poetry is aimedat amusing children with an allegory of a variety of cats. Usually, the style that children like lies in amusement in form and satirical language in use. Eliot knew it; so it is an interesting task to examine the significance of the old possum, his nickname, from the poetry for children, and the poet hidden behind the nickname. The Old Possum poetry appears to take into account what children like: a poetry collection of amusement and seriousness put together for children using lively rhythms and regular rhymes according to the characteristics of practical cats. The poetry shows a variety of each cat’s characters and habits, which, the poet believes, practically reflect various forms of human life. Above all, Eliot tried to associate practical cats in profound meditation with himself as a thoughtful, yet invisible poet and critic just like the wild, yet shy animal: a metaphor of the old possum in poetry.
