The changes in the size of human oviduct and ovary after immersion in formalin (4%, 10%) were investigated. The results were as follows : 1. After fixation, the length of oviduct was significantly reduced to 93%, but the cross sectional area of oviduct was significantly increased. The length of oviduct showed no significant difference between 4% and 10% formalin. The length of ovarian ligament was also significantly reduced to 84% after fixation. 2. After fixation, the volume of oviduct was increased significantly and showed a difference between the two fixatives. The volume of oviduct in 4% formalin has increased to 107%, as compared to 103% increase in 10% formalin. 3. After fixation, the volume of ovary was increased significantly and showed a difference between the two fixatives. The volume of ovary in 4% formalin has increased to 109%, as compared to 103% increase in 10% formalin.

Torsion of the follopian tube is an infrequent but significant cause of acute lower abdominal pain in females that is difficult to recognize preoperatively, although prompt diagnosis and timely sugical treatment are vital to salvage the oviduct. Unless a high index of suspicion is maintained for torsion of the fallopian tube in a adolescent females, this disorder may not be detected until after tubal destruction.

Torsion of the fallopian tube is an uncommon cause for acute low abdominal pain in female that is difficult to diagnose. Because it has no pathognomonic clinical symptoms or laboratory findings, a high index of suspicion is important when there is history of pelvic pathologic conditions or surgery. The early diagnosis and surgical treatment of the disease are mandatory to preserve oviduct.

OBJECTIVE: The purpose of the study was to determine the effects of co-culture with oviductal epithelial cells and Vero cells on mouse embryo. METHOD: For the control group, mouse embryos were cultured alone in Ham's F-10 with 10% FBS. Subcultured oviductal epithelial cell and Vero cell were cocultured in Ham's F-10 with 10% FBS with the mouse embryo and used as the treatment group. Development of mouse embryos were observed. Result: The development rate and hatching rate of embryos that cocultured with oviductal epithelial cell and Vero cell was significantly higher (p<0.05) than control group. When subcultured oviductal epithelial cells were co-cultured with mouse embryo, there was no significant difference in development rate and hatching rate among subculture step. When oviductal epithelial cells that have been frozen-thawed were co-cultured with mouse embryo, there was no significant difference in development rate and hatching rate among subculture step. No statistical significance was seen in the development rate and hatching rate between subcultured oviductal epithelial cells and frozen-thawed oviductal epithelial cells when cocultured with mouse embryo, Vero cells and frozen-thawed when cocultured with mouse embryo, and Vero cells and oviductal epithelial cells when cocultured with mouse embryo. CONCLUSION: Oviductal epithelial cells and Vero cell may have a stimulatory role in early mouse embryonal development compared to control in vitro. As well, there is no significant difference in development rate and hatching rate among subculture step, when early mouse embryo was cocultured with cells that subcultured and frozen-thawed.

OBJECTIVE: The present study was undertaken to examine the effects of magnesium ion in the culture medium on the development of mouse fertilized oocytes either before or after pronuclear formation, and to investigate whether the effect of magnesium ion is related with the redistributional change of mitochondria. METHODS: Fertilized oocytes obtained from the oviducts of mice at 15 hr after hCG injection before pronuclear formation (pre-PN) or 21 hr after hCG injection after pronuclear formation (post-PN) were used. The embryos were cultured for 3 days with basic T6 medium-magnesium free and various concentrations of magnesium ion, 0.0, 0.5, 1.0, 2.0, 4.0 or 8.0 mM, respectively. After culture, the developmental stages of embryos and the number of nuclei were evaluated. To observe the effects of magnesium ion on the mitochondrial distribution, fertilized oocytes were collected at 21 hr after hCG injection and cultured for 6 hr with various concentration of magnesium ion. As a control, fertilized oocytes with pronuclei at 27 hr after hCG injection were used. RESULTS: The concentration of magnesium ion to accelerate the in vitro development of mouse fertilized oocytes appeared to be at 2.0 mM for the pre-PN and the post-PN stage embryos. In the mitochondrial redistribution patterns, the embryos cultured in 2.0 mM concentration of magnesium ion showed the highest percentage (22.6%) of distinct perinuclear clustering pattern comparing to other experimental group. CONCLUSION: The effect of magnesium ion may be related to the cytoplasmic redistribution of mitochondria. This relationship seems to connect the developmental competence of preimplantation mouse embryos in vitro. These results can suggest that higher concentration of magnesium ion (2.0 mM) than those of conventional culture medium (0.2~1.2 mM) is more suitable for in vitro culture of preimplantation mouse embryos.
