Objective : Thoracic ossification of the ligamentum flavum (OLF) is a relatively rare disease. Because of ambiguous clinical symptom, it is difficult for early diagnosis of OLF and subsequent treatment can be delayed or missed. Therefore, the purpose of this study is to comprehensively assess the prevalence and distribution of thoracic OLF by magnetic resonance imaging (MRI) and coexisting spinal disease in Korean patients with back pain or leg pain. Methods : The sample included 2134 Korean patients who underwent MRI evaluation for back pain. The prevalence and distribution of thoracic OLF were assessed using lumbar MRI with whole spine sagittal images. Additionally, we examined the presence of coexisting lumbar and cervical diseases. The presence of thoracic OLF as well as clinical parameters such as age, sex, and surgery were retrospectively reviewed. Results : The prevalence of thoracic OLF in total patients was 16.9% (360/2134). The prevalence tended to increase with aging and was higher in women than in men. The lower thoracic segment of T10-11 was the most frequently affected segment. Of the 360 patients with OLF, 31.9% had coexisting herniated thoracic discs at the same level. Approximately 74% of the patients with OLF had coexisting lumbar and cervical disease. Nine (2.5%) of 360 OLF patients underwent surgery for thoracic lesion. Conclusion : The prevalenceof thoracic OLF was relatively higher than those of previous reports. And coexisting lumbar and cervical disease were very frequent. Therefore, we should check coexisting spinal diseases and the exact diagnostic localization of ossification besides lumbar disease.

Objectives : Ossification of the ligamentum flavum (OLF) is a rare cause of thoracic myelopathy. The aim of this study was to identify factors associated with the surgical outcome on the basis of preoperative clinical and radiological findings. Methods : Data obtained in 26 patients whot underwent posterior decompression for thoracic myelopathy, caused by thoracic OLF, were analyzed retrospectively. Patient age, duration of symptoms, OLF type, preoperative and postoperative neurological status using the Japanese Orthopedic Association (JOA) scoring system, surgical outcome, and other factors were reviewed. We compared the various factors and postoperative prognosis. All patients had undergone decompressive laminectomy and excision of the OLF. Results : Using the JOA score, the functional improvement was excellent in 8 patients, good in 14, fair in 2, and unchanged in 2. A mean preoperative JOA score of 6.65 improved to 8.17 after an average of 27.3 months. According to our analysis, age, gender, duration of symptoms, the involved spinal level, coexisting spinal disorders, associated trauma, intramedullary signal change, and dural adhesions were not related to the surgical outcome. However, the preoperative JOA score and type of OLF were the most important predictors of the surgical outcome. Conclusion : Early diagnosis and sufficient surgical decompression could improve the functional prognosis for thoracic OLF. The postoperative results were found to be significantly associated with the preoperative severity of myelopathy and type of OLF.

Ossification of the ligamentum flavum(OLF) is not infrequent in the cervical and lumbar regions but is very rare in the thoracic spine. We reported a 62-year-old women with left thoracic intercostal neuralgia due to an OLF. Physical and neurological examination were normal. MRI showed an OLF with compression of the thecal sac in the posterolateral aspect of the T9-T10 level. Laminectomy and removal of the ligament resulted in marked clinical improvement. OLF is known to cause thoracic radiculomyelopathy, but presentation with intercostal neuralgia only is very rare.

Objective : Ossification of ligaments within spinal canal, i.e., OPLL and OLF, is uncommon clinical entity as a cause of the progressive compression myelopathy or radiculopathy. More and more cases being reported in the field of occidental medicine, but very few cases have been reported in the field of oriental medicine. The purpose of this study is to report on oriental medical approaches to OPLL and OLF. Methods : Subjects of this study are 3 cases of OPLL and 3 cases of OLF who visited Won-kwang oriental medical hospital(Dept. of acupuncture and Moxibustion) from May, 2002 to October, 2003. These patients undergo oriental medical treatment such as acupuncture, cupping, Bee-Venom therapy and herbal medication and so on. We made a comparison JOA scores between before treatment and after treatment and we evaluated results of treatment. Results : The results of treatment in these six cases are as follows ; One case was evaluated 'Excellent', one case was evaluated 'Good', two cases were evaluated 'Fair' and two cases were evaluated 'Failure'. One of these cases had a surgical operation after discharge from this hospital. Conclusions : After oriental medical care for these cases, there are some improvements such as decrease of pains, relief of myelopathy etc. But, it had little effect on some cases, therefore we considered that more special study to find various and effective methods of oriental medical treatment for these diseases should be made.

This study was tried to evaluate possibilities for discriminating the mixture degree of wheat flour from buckwheat products. Buckwheat was milled into four grades of powder, i.e. whole grain flour (WGF), inner layer flour(ILF), middle layer flour(MLF) and outer layer flour(OLF)), and these powders were mixed with wheat flour(WF) to make mixed samples. Ash, protein and fat contents of the buckwheat flours were high in the order of OLF=WGF>MLF>ILF. On the other hand, WF showed a similar content to OLF in ash and protein, and to ILF in fats. Potassium and magnesium contents were higher in all the buckwheat powder than in the wheat flour. Flavonoid contents were higher in order of OLF>WGF=MLF> ILF, but it was not in wheat flour. Although the reliable correlation between mix ratio and components, i.e. mag nesium or ash analyzed were found, it did not seem to reflect sufficiently the expected variations of contents of original material components. Also, compositions of commercial buckwheat products were analyzed to evaluate the mixed ratio of buckwheat flour and wheat flour. The results suggest that the components analyzed in this study as putative marker were not good in determining whether or how much buckwheat products contained wheat flour.

In this Paper, we proposed a new voltage stability analysis algorithm. Using $ $ calculated by the optimal load How method(OLF), it rapidly and correctly calculates a PV curve with voltage collapse point in the stable region. OLF can calculates voltage collapse point as well as the operating point in the stable region. Specially, $ $ indicates the relative distance between voltage collapse point and the solution in the unstable region. In the study of a sample system, we verified the superiority of proposed algorithm.

Ossification of ligamentum flavum(OLF) is a type of ectopic bone formation developed within the spinal ligament. Thoracic myelopathy is common symptom of OLF but radiculopathy is uncommon. We present 3 operated cases of OLF. Two showed myelopathy and one radiculomyelopathy. Main symptoms were motor weakness, sensory disturbance, incoordination of both legs, and back pain. One patient complained of left girdle pain in T4 dermatome. Deep tendon reflex(DTR) was increased in all cases. The diagnosis was made from myelogram, CT and MRI. Sufficient posterior decompressive laminectomy and medial facetectomy were performed. Postoperative diagnosis was comfirmed by histopathological examination. One patient could return to work 3 months after operation and two patients showed satisfactory improvement 2-3 months after operation. Early diagnosis and appropriate surgical treatment were prerequisite of good outcome.
