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.

A soft ruptured thoracic disc herniation is very rare. We have experienced a ruptured T5-6 disc herniation which was migrated into spinal canal and compressed spinal cord posteriorly. It was difficult to differentiate it from cord tumor. Posterior laminectomy offers a better chance of removal than does the anterolateral or posterolateral approach this case.
