3.The Analgesic Effect of Intraarticular Bupivacaine and Morphine after Arthroscopic Knee Surgery.
Journal of the Korean Knee Society 1998;10(1):114-118
Many authors have studies to relieve the pain after arthniscopic knee surgery. We undertook a randomized, double-blind trial to compare the efficacy of intraarticular morphme and bupivacaine between arthroscopic meniscus surgery group and cruciate ligament reconstruction group. As an results, intraarticular injection of morphine-bupivacaine combination is effective to control pain after minor athroscopic surgery such as menisectomy and meniscal repair ancf intraarticu]ar injection of mor- phine-bupivacaine combination is not effective to relieve pain after major arthroscopic surgery including cru- ciate ligament reconstruction. So, more potent analgesics should be adminishated.

PURPOSE: DNA mismatch repair gene is responsible for hereditary nonpolyposis colorectal cancer. But it is not well known its role in sporadic colorectal cancer patients. We analysed normal hMSH2, hMLH1 protein expression in colorectal adenocarcinoma tissues and corresponding normal tissues to find out the role of mismatch repair gene in sporadic colorectal cancer by Western blotting. METHODS: Normal hMSH2 and hMLH1 protein expression was studied on 25 colorectal cancer and corresponding normal tissue by Western blot with hMSH2 and hMLH1 monoclonal antibody. Normal protein band was expressed on 100 kD in hMSH2 and 87 kD in hMLH1. SW480 and LoVo cell line was used as positive and negative control for hMSH2 and LoVo and SW480 as positive and negative for hMLH1. And we analysed the relation between the hMSH2, hMLH1 protein expression and clinicopathological parameters. RESULTS: It was 2 cases (8%) that both hMSH2 and hMLH1 protein expression was not observed. Three cases (12%) were negative for hMSH2 and 2 cases (8%) for hMLH1. One or both hMSH2, hMLH1 protein expression was not observed in 7 cases (28%) in total. There was no correlation for proximal occurrence (25% vs 35%), young age (37.5% vs 23.5%) and lymph node metastasis (50% vs 47%). But poorly and mucinous differentiation was regarded as having relation with negative expression of hMSH2 and hMLH1 (50% vs 17.6%) but not significant statistically. CONCLUSION: Sporadic colorectal cancer with negative expression of normal hMSH2 and hMLH1 protein showed no relation to younger age, proximal site preference and lymph node metastasis. But it was suggested that mismatch repair gene protein was involved in cancer cell differentiation in sporadic colorectal cancer.

The evaluation of urinary calculi was done in 84 patients of paraplegia and quadriplegia due to traumatic spinal cord injury. These patients were diagnosed by KUB and intravenous urography at National Veterans Hospital during 6 years from Jan. 1975 to Dec. 1980. The results were as follows; 1. Overall incidence of urinary calculi was 38.1 %; Incidence of renal calculi was 8.3%, ureteral calculi 4.8%, and urinary bladder claculi 32.1%. 2.Relation of neurological level and incidence of urinary calculi were as follows; Cervical injury in 34.8% upper thoracic injury in 40.0%, lower thoracic injury in 45.0%, and lumbar injury in 36.5%. 3. Laterality was not toplay a role information of urinary claculi. 4. The urinary calculi were developed 62.5% during the first 36 months following spinal cord injury. 5. The recurrence of urinary calculi was 40.6%; True recurrence was 15.6% and pseudo recurrence was 25.05.

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%).

8.A Case of Extensive Spinal Cysticercosis Involving the Whole Spinal Canal in a Patient with a History of Cerebral Cysticercosis.
Yonsei Medical Journal 2009;50(4):582-584
Although cysticercosis is the most common parasitic disease affecting the central nervous system, spinal cysticercosis is rare. A rare form of spinal cysticercosis involving the whole spinal canal is presented. A 45-year-old Korean male had a history of intracranial cysticercosis and showed progressive paraparesis. Spinal magnetic resonance scan showed multiple cysts compressing the spinal cord from C1 to L1. Three different levels (C1-2, T1-3, and T11-L1) required operation. Histopathological examination confirmed cysticercosis. The patient improved markedly after surgery.

Mutation in the p53 suppressor gene is the most common genetic alteration found in human cancers including primary brain tumors. Ki-67 labeling index(LI) is known to be a marker of proliferating activity. The purpose of this study was to verify whether an immunohistochemical expression of p53 antibody and Ki-67 LI could be related to different clinicopathologic parameters including histologic grade, size, invasiveness and recurrence of the brain tumors. Materials were based on the 147 surgically resected brain tumors during the last two years. Of the 147 brain tumors, there were 35 astrocytic tumors, 35 meningiomas, 10 oligodendrogliomas, 7 craniopharyngiomas, 5 dysembryoplastic neuroepithelial tumors, 4 medulloblastomas, 5 ependymomas, 23 pituitary adenomas, 9 schwannomas, and 14 other brain tumors. The p53 expression and Ki-67 LI were higher in malignant brain tumors including astrocytic tumors, medulloblastoma, PNET and gliosarcoma. The p53 positivity was correlated with histologic grades and tumor recurrence. The brain tumors with a high Ki-67 LI(>6%) also showed a close relationship to a higher histologic grading, radiological invasiveness and recurrence. There was no evident correlation with the age and tumor size with p53 expression and Ki-67 LI. These results suggest that p53 overexpression and high proliferation potential of the tumor cells are associated with the higher histologic grade and aggressive clinical course in the central nervous system tumors.

Journal of Korean Society of Medical Informatics 2007;13(4):393-401
OBJECTIVE: As the rapid progress of aged society, there must be solutions of preparation against unpredicted accidents for aged solitary people. The most important thing that we must consider is the unconstraint of daily life. So, we are to develop a system and algorithm which meet our objectives. METHODS: We have monitored the degree of activity of the aged solitary person. The CCD camera was used not to disturb the daily activity and we evaluated the degree of activity using image processing on personal computer. The activity monitoring during night was assumed by sleeping on the bed, so the major method was breath monitoring during sleeping. On the other hand, daily activity was monitored by wide viewing camera in the living room. To prevent the privacy trouble, the acquired image was converted to binary form and the degree of breath and moving factor was estimated. RESULTS: In this paper we propose a new processing algorithm to accurately measure breathing characteristics in sleep apnea sufferers. We improved the conventional center-of-mass method and further applied the projection-profile method. As a result, we have improved breath measurement accuracy. In a comparison with conventional polysomnography, our method was 92% effective in detecting apnea cases. CONCLUSION: As a result of this study, we can monitor sleep apnea more simply and with no sleep interference. In measuring the activity of daily life, these improved algorithms were applied. So, we established a monitoring method of no-constrained, quantitative measurement for the aged solitary people during the whole day.
