From 1960 through 1965, 39 cases with epileptic seizure caused by the Cystricercus cellulosae were experienced at Kaejong Mental Hospital, Okku-Gun, Chollapukdo province. The present study was carried on at the area of Chollapukdo province where Cysticercus cellulosae cases were frequently reported. Thrity-nine Cystricercus cellulosae cases(35 male and 4 female) with epileptic seizure visited Kaejong Mental Hospital . Okku-Gun, Chollapukdo during the years of 1960-1965 from various Gun(county): Okku-Gun 13, Kimje-Gun 7, and Soonchang-Gun 6. The high incidence was found at the age group of 20-49 years and the distribution of 214 subcutaneous nodules were as follows: Trunk 56.6 percent, upper extremities 26.6 percent, head and neck 9.3 percent, lower extremities 7.5 percent. According to the address of above 39 cases, taenia infestation of the inhabitants in the area was examined by questionaire form. Plain rural area (Maryong-Ri, Okku-Gun); Among 803 persons interviewed, 4.0 percent or 32 complained the output of Taenia segments. The male group showed higher incidence (6.4 percent) than the female(1.5 percent) . The highest incidence was observed at the age group of 30-39 years. Most of the inhabitants of the area had the eating habit of raw beef and pork. Mountainous rural area(Bok-Heung-Myun, Soonchang-Gun); Among 542 persons interviewed, 33 or 6.1 percent complained Taenia infection. The higher incidence was observed in the male group(8.7 percent) than in the female group(3.1 percent) , and also at the age group of 20-49 years. They had eating habit of raw beef and pork. The species of adult worm were identified by morphological examination. Totally 36 adult worms(Taenia saginata 21, T. solium 15) were obtained from 26 cases, and it was experienced that 5 T. solium were eliminated from one person.

This study was performed to assess the accuracy of 31P magnetic resonance spectroscopy(MRS) in the evaluation of myocardial ischemia in cats. Twelve cats underwent myocardial ischemia and reperfusion induced by 90 minutes ligation followed by 90 minutes recirculation of the left anterior descending coronary artery (LAD). MRS was performed using a 4.7T Biospec MRS/MRI system (Bruker, Switzerland). An inner diameter 1.5cm-sized doubly tuned surface coli was used for the collection of the MR signal. The coli was implanted to the epicardial surface at the expected area of infarction. 31P MRS was acquired before and during the periods of ischemia and reperfusion with 5-minute to 30-minute of intervals. After completion of the 31P MRS study, animals were sacrificed and the hearts were excised for 2,3,5-triphenyl tetrazolium chloride (TTG0 histochemical staining. The area of infarct was measured on the photographs of TTG stained heart slices using a computer programmed planimetry and the results were compared with those of the 31P MRS study. The level of phosphocreatine (PCr) was decreased to 28.2±6.9% of the baseline level 90 minutes after occlusion and recovered to 43.8±4.8% of the baseline level at the end of the reperfusion. A 50% depletion of PCr was reached 5 minutes after the LAD occlusion. The ATP was decreased to a 26.6±3.6% of the baseline level 90 minutes after occlusion and recovered to a 35.9±6.0 of the baseline level 90 minutes after reperfusion. The decreasing rate of ATP was slower than that of PCr showing a 50% of depletion 15 minutes after occlusion. The PCr/ATP ratio was 1.16±0.09 at the baseline, decreased to 0.88±0.07 at 30 minutes of occlusion, and then progressively increased during the late ischemic and reperfused periods. The ratio of the infarcted area to the effective signal area of the surface coli was inversely correlated to the ATP (r=0.68) and PCr (r=0.40) levels obtained at the end of reperfusion. In conclusion, 31P MRS reflects the changes in myocardial high energy phosphorous metabolism during the actue ischemia and reperfusion. If on adequate localization technique is feasible, 31P MRS can be used clinically in the diagnosis and monitoring of the patients with acute myocardial infarction.

OBJECTIVE: We applied chest radiographs to scoliosis screening for conscription. Prevalence, types of scoliosis, and insight of examinees with scoliosis were investigated. METHODS: In this study, chest radiographs of 2417 males, who had been given an examination for conscription at the Seoul Regional Military Manpower Administration from April 2009 to May 2009, were analyzed. The prevalence of scoliosis more than a 10 degrees Cobb angle was calculated. The insight of scoliosis was investigated in every examinee and thoracolumbar radiographs were checked in those examinees with more than a 20 degree Cobb angle. RESULTS: Among 1904 males, 477 (19.7%) exhibited scoliosis involving more than a 5 degrees Cobb angle were and 131 (5.4%) exhibitedmore than a 10 degree Cobb angle. In those 131 cases, 18 (13.7%) had a known history of problems with scoliosis. Among the group measuring less than a 10 degree Cobb angle, 1.7% of them misunderstood scoliosis. Insight of scoliosis increased according to the severity of spinal curvature; however, nearly half of the cases with a 20 degree or greater Cobb angle had no insight with respect to their scoliosis. CONCLUSION: In male adolescents, the prevalence of scoliosis with a greater than 10 degree Cobb angle was 5.4% and there was a low insight with respect to scoliosis.

OBJECTIVE: The goal of this retrospective study was to assess clinical and radiographic outcomes of posterior surgical decompression with stabilization followed by image-guided robot Cyberknife radiosurgery for encircling malignant tumors of the spine. METHODS: From August 2008 to December 2009, 14 consecutive patients with a malignant spinal metastatic lesion with cord compression were treated at the author's institute. Patients underwent on a decompressive surgery by the posterior approach, and latent unstable spines were stabilized with instrumentation. After recovery, radiosurgery was administered at doses ranging from 16 to 26 Gy (mean 20.1Gy) prescribed to the 75-85% isodose line that encompassed at least 95% of tumor volumes. Visual Analogue Scale, American spine injury association grades, and MRI with gadolinium enhancement were used to monitor pain, neurology, and radiological outcomes, respectively, after the radiosurgery. RESULTS: No acute radiation-induced toxicity or new neurological deficit occurred during the follow-up period (mean 4.5 months). Axial pain improved in 10 out of the 14 patients. No hardware failure was encountered. At 3-6 months after the Cyberknife radiosurgery, local control and effective therapeutic rates were both 80%(8/10) and no lesion enhancement on vertebral bodies or pedicles was visualized by MRI. CONCLUSION: Posterior decompression with stabilization followed by radiosurgery of residual tumor in the anterolateral region is useful in cases where an anterior approach or a circumferential approach is not an option due to medical condition. Longer term follow-up is required to evaluate survival and late toxicities.

Purpose:
To evaluate the intraocular pressure (IOP) reduction, success rate and prognostic factors after trabecular micro-bypassstent implantation in patients with open-angle glaucoma.
Methods:
We retrospectively reviewed 33 eyes of 33 patients with open-angle glaucoma who were followed-up for more than6 months after trabecular micro-bypass stent implantation. The success of surgery was defined as an IOP ≤ 21 mmHg and anIOP reduction ≥ 20% from baseline, regardless of whether glaucoma medication was used.
Results:
During the follow-up at 6 months after trabecular micro-bypass stent implantation, the IOP was significantly decreasedfrom 23.70 ± 6.26 mmHg before surgery to 18.03 ± 4.64 mmHg after 6 months, and the glaucoma medication was significantlydecreased from 3.73 ± 0.67 before surgery to 3.43 ± 0.67 after 6 months (p < 0.001 and p = 0.027, respectively). The successrate at 6 months was 33.7 ± 5.5% in patients with only trabecular micro-bypass stent implantation. Using multiple regressionanalyses of the risk factors, age was associated with success rate (odds ratio, 1.076; 95% confidence interval, 0.996-1.164;p = 0.045).
Conclusions
In patients in the Republic of Korea, trabecular micro-bypass stent implantation was an effective surgery for IOPreduction, and showed a better surgical success rate in younger patients.
