OBJECTIVE: To evaluate whether the rate of early mouse embryonal development could be enhanced by cumulus cell coculture in vitro. METHODS: Ham's F-10 culture media supplemented with 0.4% bovine serum albumin were used. Two-cell F1 mouse embryos were cultured in media with or without cumulus cells of female ICR mouse embryo for 96 hours, and the rates of embryonal development were observed and compared. RESULTS: The percentage of hatched blastocyst in the coculture group was significantly higher than that in the control group by 87.3% vs 64.8% respectively (p< 0.05). CONCLUSION: This study provides confirmative information that cumulus cell coculture will be useful in enhancing early mouse embryonal development.

Aneurysmal subarachnoid hemorrhage in a pregnant woman is a rare catastrophic situation that places both the mother and fetus at high risk. When this situation arises, numerous relevant issues must be individualized in the effort to reduce hazards threatening both the mother and fetus. A 29 year old woman who was 39 weeks pregnant presented with a subarachnoid hemorrhage, secondary to a ruptured left ophthalmic artery aneurysm. Following initial full recovery, the simultaneous sequence of cesarean section followed by aneurysmal clipping was electively underwent. Successful maternal and perinatal outcome was achieved. The anesthetic management of the case is described and discussed.

Although its high successability in numerous corneal diseases, penetrating keratoplasty in certain conditions, such as chemical burn, ocular pemphigoid, Stevens-Johnson syndrome, severe dry eye, and recurrent graft rejection still has had poor outcomes. So far, many keratoprostheses have been developed, but none of them showed consistent successful results. The authors made two models of keratoprosthesis using expanded polytetrafluoroethylene (PTFE) as a skirt and these models were implanted to 30 and 5 rabbit corneas by intralamellar fixation respectively. Expanded PTFE was well-known for its biocompatibility and porous structure which fibrovascular tissue can grow in. However, both of the models extruded from the cornea in all cases and retention period was 1 month in average. These poor results are thought to be mainly due to previously known enzymatic degradation. To obtain better result, modification of the models and surgical techniques are needed. Several possible modifications are described in this article.
