  • This study was carried out for the evaluation on the sociomedical characteristics of 1,580 cases who had recieved vasectomy and laparoscopic sterilization at the Busan Family Planning Clinic from January 1975 to December 1973. The results obtained were as follows: 1. In age distribution, the most predominant age group consited of 30.34 years as 44.7%. In regional distribution, the most predominant region was Youngdo Ku in the vasectomy group and Dong Ku in the laparoscopic sterilization group. 2. The educational level showed that the high school graduates(49.2%) in the vasectomy group and the primary school graduates(47.0%) in the laparoscopic sterilization group were the highest each other. 3. The most predominant experienced contraceptive method before accepted permanant sterilization operation was oral pills and non-experienced contraceptive method group was 54.1% of the total. 4. By the span of marital life before accepted permanant sterilization operation, the 5-9 years group was the highest. 5. The average number of living children per family was 2.54 in the vasectomy group and 3.0 in the laparoscopic sterilization group. 6. The average frequency of pregnancy per case was 2 in the vasectomy group and 3 in the laparoscopic sterilization group and the most predominant frequency of induces abortion was 1 per case. 7. The most predominant motive of accepting the sterilization operation were family planning education at the reserve forces training in the vasectomy group and at the mother's club in the laparoscopic sterilization group. 8. By the residing status of the cases, rented room was the highest as 69.4%.

  • This experiment was carried out to evaluate the effect of mouse early embryonic development in vitro by co-culture with bovine and porcine oviductal epithelial cells(BOEC and POEC). The 2-cell embryos were collected from the oviducts of the superovulated and mated does with D-PBS/15% FCS at 48 hours after hCG injection. The in vitro developmental rate of blastocyst formation and the number of nuclei in the embryos were examined. For a comparative study of in vi패 and in vitro development, the fresh blastocyst which developed in vivo for 120 hours after hCG injection was collected from the uterus, and their numbers of nuclei were also counted. The higher developmental rates of blastocyst formation was a, pp.ared from 91% to 97% when the embryos were co-cultured with a monolayer of bovine or porcine oviductal epithelial cells in TCM 199 or Ham's F-10 and MediCult IVF media. No significant difference in developmental rates was shown between bovine and porcine oviductal eptithelial cells. The number of nuclei in the embryos cultured for 72 hours under each conditions was significantly reduced it than blastocyst in vitro conditions. The number of nuclei in embryos cultured in TCM 199, Ham's F-10 and Medicult IVF medium were counted 68.1$\pm$6.00, 67.3$\pm$4.49, 66.4$\pm$5.64, and 94.3$\pm$8.61, 92.5$\pm$7.60, 92.1$\pm$6.10 with BOEC and 93.3$\pm$5.80, 92.9$\pm$6.53, 92.3$\pm$7.35 with POEC coculture, respectively. These numbers were lowered than 107.2$\pm$7.43 in vivo conditions. In conclusions, the coculture between the mouse early embryos, and oviductal epithelial cells of BOEC and POEC give to improve the developmental and hatching rates of blastocyst but in vivo culture systems for the growth of nuclei were ineligible than in vitro conditions.
