Compared to the lumbar region, it is very rare to encounter far lateral disc herniation in the cervical spine, and because of this, correct diagnosis before surgery is difficult: the condition can, however, be identified through the use of advanced MRI imaging techniques. In this case, far lateral disc herniation at C7-T1 was effectivery removed through posterior laminoforaminotomy, and soon after surgery, the patient's symptoms showed complete remission.

OBJECTIVE: This study was carried out to evaluate the effect of the isolation methods of inner cell mass from mouse blastocyst, types of feeder cells and treatment time of mitomycin C on the formation rate of ICM colony. METHODS: The inner cells were isolated by conventional immunosurgery, partial trophoblast dissection with syringe needles and whole blastocyst co-culture method. Commercially available STO and primary cultured mouse embryonic fibroblast (pMEF) feeder cells were used, and mitomycin C was treated for 1, 2 or 3 hours, respectively. The formation rate of ICM colony was observed after isolation of ICM and culture of ICM on the feeder cells for 7 days. RESULT: The ICM colony formation rate on STO were significantly higher in partial trophoblast dissection group (58%) than that in immunosurgery (12%) or whole blastocyst culture (16%) group (p<0.05). The formation rate on pMEF feeder layer was higher in partial trophoblast dissection (88%) and whole blastocyst culture (82%) group than that in immunosurgery (16%) group (p<0.05). When mitomycin C treated to pMEF for 2 hours, the formation rate of 88% was significantly higher than those of other conditions. CONCLUSIONS: Above results showed that the efficient isolation method of ICM from blastocyst was the partial trophoblast dissection and the appropriate treatment time of mitomycin C was 2 hours. However, the subculture of ICM colony and characterization of stem cells should be carried out to confirm the efficacy of the partial trophoblast dissection method.

In the present studies, changes of the glial fibrillary acidic protein (GFAP) expression in the astrocytes of the rat hippocampal formation were examined in response to the bilateral carotid artery occlusion for 10 minutes along with a decrease of mean arterial blood pressure (MABP) to 50 mmHg. Their relations to neuronal viability were also studied by H&E staining. In early postischemic period, mild increase of the GFAP expression was observed and this was not only confined to the mild-necrotic (CA3 and dentate gyrus) regions but also in the non-necrotic regions (CA1 and subiculum) at postischemic 8 h. This suggest that astrocytosis during early postischemic period may be resulted from nonspecific reaction associated with changes in brain environment. In contrast, in late phase of the postischemia, a marked increase of the GFAP expression was observed at day 4. Moreover, cell bodies were significantly larger and many prominent and numerous processes were observed, suggesting that this may also contribute to the significant increase in the GFAP expression. Importantly, these cellular changes were only confined to the regions of massive necrosis such as subiculum and inner granular cell layer of dentate gyrus and were not observed in the non-necrotic regions (except CA1). In contrast, the GFAP expression in astrocytes were returned to control levels in mildly damaged CA3 region by 4 days. Thus reactive astrocytosis with upregulation of the GFAP in the late postischemic period with structural transformation in the regions of massive necrosis may contribute to the damages in the neighboring neurons.

OBJECTIVE: To examine the effects of coculture with human oviductal cells regarding the development of 1-cell stage ICR mouse embryos and to investigate the effects of duration and start time of coculture. MATERIALS AND METHODS: ICR mice were superovulated with PMSG/hCG and 1-cell stage mouse embryos were recruited. 1-cell mouse embryos were cocultured on human oviductal cells in a CO2 incubator(coculture group) and were cultured on 0.4 % BSA+HTF media(control group)(Experiment 1). 1-cell mouse embryos were cocultured on human oviductal cells for 36, 44, 52, 60 hours after hCG IP respectively, and then were transferred to 0.4 % BSA+HTF media(Experiment 2). In comparison, 1-cell mouse embryos were cultured by using 0.4 % BSA+HTF media, and then were transferred to human oviductal cell coculture system using the same schedule(Experiment 3). Afterward, they were examined regarding the development to 2-cell, 4~8 cell stage mouse embryos, morulas and blastocysts. RESULTS: In experiment 1, the developmental rates to 2-cell embryos of coculture group and control group were 97.3 % and 98.7 %, respectively. After 2-cell embryos, coculture group showed significantly higher developmental rate than control group (p<0.05). In experiment 2, the developmental rates after 2-cell embryos showed the significant differences. The groups with coculture effects removed before post-hCG 60 hours showed significantly lower developmental rates (p<0.05). In experiment 3, the developmental rates after 2-cell embryos were higher when the coculture started at an earlier stage. Furthermore, the groups which were cocultured from post-hCG 52 hours exhibited significant lower developmental rate than the groups which were cocultured continuously (p<0.05). CONCLUSION: The coculture with human oviductal cell could improve the development of the embryos in vitro and might mimic the natural physiological condition better than media environment. The degree of improvement was more pronounced when the coculture started at an earlier stage and the duration of coculture was longer. More importantly, the changes of culture condition at post-hCG 52 hours in which secondary mitosis occurs, have significant detrimental effects on growth and development of mouse embryos.
