A prospective study of vitamin B6, B12, folate, and homocysteine levels was carried out in 7 kidney transplant(KT) recipients. The first sample for the basal level was drawn on the morning of the KT day before the start of cyclosporine injection. Thereafter, serial blood samples were taken every day until the serum creatinine level decreased below 1.5 mg/dl and then every 2 or 3days until discharge. The serum creatinine level decreased to below 1.5 mg/dl within 3days except for cases 4 and 6. The homocysteine levels decreased markedly in synchronisation with serum creatinine levels increased during the first 7days and then declined together with serum creatinine levels but went up again after a few days. The levels of B6, and vitamin B12 do not continue to decrease after the levels of serum creatinine have decreased to 1.5mg/dl, while homocysteine levels go up progressively. In conclusion, contrary to our expectation, the level of homocysteine rebounds a few days after KT following a transient decline. A deficiency of folic acid, vitamin B6 and vitamin B12 does not seem to cause hyperhomocysteinemia in KT recipients. It is necessary to pay attention to hyperhomocysteinemia in KT recipients, especially when the recipients have an atherosclerosis-related complication.

The effect of IDU and cryocautery in the treatment of Herpes Simplex Keratitis was presented. The cryoapplicator was a model of Krwawlcz probe (2 mm in diameter) which was refrigerated in a mixture of dry ice and methyl alcohol. The applicator was appJied on the lesions 7 seconds each and antibiotics and atropine solutions were instilled. A good result was experienced in the treatment of several cases of dendritic kenititis by freezing the corneal lesions by means of cryoappJicator, which had not been responded to IDU therapy speedy. The deep neovascularization of the cornea in a case of stromal keratitis was disappeared after cryocautery for the treatment of the superficial corneal ulcers.

Recently, the frequency of meniscal injury of knee has been increasing due to increase of sports activities. It has been known that bucket handle tear is the most common type of the entire injuries of the meniscus. We found 127 cases of meniscal tears and experienced 42 cases of bucket handle tears in the arthroscopic findings from Jan. 1991 to April 1994 in our hospital. We analysed 31 cases which were followed up for at least 1 year. The purpose of this study is to analyse the locking history and frequency, to discuss the several types of bucket handle tear in arthroscopic view, to introduce three portal techniques using posteormedial or posterolateral portal to resect the meniscus, and to analyse our clinical results. So we concluded as follows. 1. Among the 31 cases, 23 cases(74%) had an episode of locking. 2. We found many different types of bucket handle tears in arthroscopic view and the most common type was complete tear in a classic type(11 cases). 3. We were able to resect the meniscal fragment very easily using posteromedial or posterolateral portal. 4. We obtained satisfactory results in 24 cases(77%).

Kainic acid[KA], a glutamic acid analogue, has been widely used as a excitotoxin in the study of neurotoxicity due to its ability to induce strong excitation and to increase intracellular calcium concentration of the mature central nervous system[CNS] neurons. However, it is not well known whether KA is also strongly cytotoxic to the neurons of the postnatal brain. We have injected KA into rats at different developmental stages and have investigated the changes in the expression of c-fos[transcriptional factor and a marker of neuronal activity], heat shock proetin 72[hsp 72, a neuronal injury marker], and glial fibrillary acidic protein[GFAP, a neuronal injury marker] mRNAs, which are known to be increased in KA-induced neurotoxicity, and glyceraldehyde 3-phosphate dehydrogenase [GAPDH, a house keeping gene] mRNAs with in situ hybridization histochemistry using specific riboprobes. The expression of c-fos mRNA was first identified in the CA3 area of hippocampus from 6hr after KA treatment in P7 rats. The c-fos mRNA-expressing area and the level of expression was gradually increased from P7 to adult. Hsp 72 mRNA was first expressed in the dentate gyrus and hippocampus from 6hr after KA treatment in P2l rats. In the adult rats, hsp 72 mRNA was broadly expressed in the brain at 2hr after KA treatment. The increase of GFAP mRNA expression was first identified in Pl4 rat brain from 6hrs after KA treatment, and by the development of brain it tends to appear earlier. The expression of GAPDH mRNA, however, did not show changes after KA treatment except for the adult rats showing a slight decrease at 12hr after KA treatment. These results suggest that KA may offer different level of cytotoxicity to the developing neurons by their developmental status and the difference may be correlated with the completion of synaptogenesis and increase of KA receptor.

STUDY DESIGN: A retrospective study. OBJECTIVES: To assess the efficiency of undercorrection and transpedicular screw fixation through a posterior approach in osteoporotic spine fractures with a thoracolumbar kyphotic deformity. SUMMARY OF LITERATURE REVIEW: The surgical treatment of osteoporotic spine fractures with a thoracolumbar kyphotic deformity requires extensive surgical procedures to obtain complete restoration of the sagittal alignment, but it has a few technical limitations due to insufficient mechanical stability at the bone-screw interface. A special strategy is essential for transpedicular screw fixation for osteoporotic spine fractures with a thoracolumbar kyphotic deformity. MATERIALS AND METHODS: We reviewed 14 osteoporotic spine fracture cases, with a thoracolumbar kyphotic deformity, which had undergone undercorrection and transpedicular screw fixation through a posterior approach, between March 2000 and June 2003, with an average follow-up period of 15. 2 months. According to the Jikei grade of the osteoporosis, 9 and 5 cases were grades 2 and 3, respectively. As a radiographic assessment, we measured the kyphotic angles of the fused segments on the preoperative, postoperative and last follow up thoracolumbar lateral views on standing using Cobb's method, and also assessed the kyphotic angle correction (KAC). The clinical results were evaluated at the last follow-up. RESULTS: The kyphotic angles at the preoperative, postoperative and last follow-up were 33.5 degrees +/- 9.3, 22.4 degrees +/- 6.9 and 24.7 degrees +/- 6.8, respectively. We obtained a mean KAC gain of 11.1 degrees postoperatively (p<0.05), but a loss of 2.3 degrees at the last follow-up (p>0.05). The clinical results were analyzed as good, fair and poor in 8, 5 and 1 case, respectively. Fusions were achieved in all cases. CONCLUSIONS: Undercorrection and transpedicular screw fixation for a thoracolumbar kyphotic deformity in osteoporotic spine fractures can be one of the alternatives to avoid fixation failure and an extensive surgical procedure.

PURPOSE: This study was performed to evaluate the results of surgical treatment of Nirschl procedure for intractable lateral epicondylitis of the elbow. MATERIALS AND METHODS: We retrospectively reviewed the functional records of surgically treated 21 cases from the 196 cases of lateral epicondylitis, which had been followed up at least 12 months from March 2000 to May 2003. Surgery was generally considered to be indicated if six months of conservative treatments since the first diagnosis had led to no improvement of the symptoms. The patients were evaluated by assessing of Pain Analog Scales (PAS) score. The objective outcomes of all patient after surgery were investigated according to the criteria by Roles and Maudsley. RESULTS: The mean PAS score followed up for 12 months postoperatively, had indicated significant improvements (p<0.001): 0.31 points (range, 0-2) at rest, 1.22 points (range, 0-3) at daily activities, and 2.25 points (range, 0-5) at sports and occupational activities. According to the Roles and Maudsley scores, there were 12 excellent, 7 good, 2 fair from the total of 21 cases; therefore, 19 (90%) cases showed the satisfactory results. CONCLUSION: The surgical treatment using the Nirschl procedure for intractable lateral epicondylitis of the elbow is considered as one of recommendable methods for the cases of no response at the conservative treatment.
