PURPOSE: Hyperhomocysteinemia has been identified as an independent risk factor in arterial and venous thrombosis. Mutations in genes encoding methylenetetrahydrofolate reductase (MTHFR), involved in the metabolism of homocysteine, may account for reduced enzyme activity and elevated plasma homocysteine levels. In this study, we investigated the interrelation of MTHFR C677T genotype and level of homocysteine in patients with arterial and venous thrombosis. MATERIALS AND METHODS: We retrospectively reviewed the medical records of 146 patients who were diagnosed as having arterial and venous thrombosis. We excluded patients diagnosed with atrial fibrillation. We examined routinely the plasma concentration of total homocysteine level and MTHFR C677T polymorphism for evaluation of thrombotic tendency in all patients. Screening processes of MTHFR C677T polymorphism were performed by real-time polymerase chain reaction. RESULTS: Investigated groups consisted of thrombotic arterial occlusion in 48 patients and venous occlusion in 63 patients. The distribution of the three genotypes was as follows: homozygous normal (CC) genotype in 29 (26.1%), heterozygous (CT) genotype in 57 (51.4%), and homozygous mutant (TT) genotype in 25 (22.5%) patients. There were no significant differences among individuals between each genotype group for baseline characteristics. Plasma concentration of homocysteine in patients with the TT genotype was significantly increased compared to the CC genotype (P<0.05). CONCLUSION: We observed a significant interaction between TT genotypes and homocysteine levels in our results. The results might reflect the complex interaction between candidate genes and external factors responsible for thrombosis.

Journal of the Korean Radiological Society 1995;32(1):145-152
PURPOSE: To evaluate the radiological patterns of vascular invasion in peripheral cholangiocarcinomas. MATERIALS AND METHODS: Hepatic arteriography and portography in 20 cases with cholangiocarcinoma including 12 cases with anglographic CT were retrospectively analized. RESULTS: The arteriography showed no arterioportal shunt, hypertrophy of tumor vessel, or tumor staining extending to central portion of the mass in all cases. However, doughnut shaped peripheral tumor staining was seen until late hepatogram phase in 12 cases and compensatory hyperperfusion around the mass was seen in six cases(eight cases if include arterial CT). Encasement of tumor vessel was seen in 12 cases, and hypertrophy of feeding vessel in nine cases. On portogrphy, the filling defect on segmental portal branch could be demonstrated only in 11 cases. Shape of the portal defect was tapered narrowing in six cases, abrupt narrowing in two cases but intraluminal nodular filling defect was not seen. Remainning three cases were difficult to define the shape. On seven cases of CT during arterial portography, three cases showed mass shaped defect and four showed segmental defect but three of them could demonstrate the partially preserved portal flow in defective portal area. CONCLUSION: Hepatic arteriography in peripheral cholagiocarcinoma showed no evidence of hypertrophy of tumor vessels and tumor stain extending to central portion but peripheral staining on late hepatogram phase and compensatory hyperperfusion could be seen. Portal vein was more commonly involved through perivascular connective tissue invasion rather than by direct extension into the portal lumen.

Journal of Korean Medical Science 2005;20(4):529-534
There have been many epidemiological and clinical researches on chronic fatigue (CF) and chronic fatigue syndrome (CFS) since the 1990s, but such studies have been quite limited in Korea. The aim of this study was to investigate the point prevalence of CF and CFS in patients who visited community-based eight primary care clinics in Korea. The study subjects were 1,648 patients aged 18 yr and over who visited one of eight primary care clinics in Korea between the 7th and 17th of May 2001. The physicians determined the status of the subjects through fatigue-related questionnaires, medical history, physical examination, and laboratory tests. The subjects were categorized into no fatigue, prolonged fatigue, CF and then CF were further classified to medically explained CF (Physical CF and Psychological CF) and medically unexplained CF (CFS and idiopathic chronic fatigue). The point prevalence of CF and CFS were 8.4% (95% CI 7.1-9.7%) and 0.6% (95% CI 0.2-1.0%). Medically explained CF was 80.5% of CF, of which 57.1% had psychological causes. The clinical characteristics of CFS were distinguished from explained CF. CF was common but CFS was rare in community-based primary care settings in Korea.

The bone mineral densities of 60 middle school boys were measured with dual photon absorptiometry to define the influence of Taekwon-Do. They were divided into Taekwon-Do and control group, each comprising 30 boys. The bone mineral densities of the head, trunk, pelvis, both upper and lower extremities, and body total were measured. The results were as follows. 1. The BMD of head was 1.668 ± 0.153 in Taekwon-Do and 1.554 ± 0.153 0.167 in control. It was significantly increased in aekwon-Do(p <0.05). 2. The BMD of trunk was 0.378 ± 0.153 0.044 in Taekwon-Do and 0.353 ± 0.153 0.053 in control. There was no significant difference(p >0.05). 3. The BMD of pelvis was 1.648 ± 0.153 0.112 in Taekwon-Do and 1.444 ± 0.153 0.215 in control. It was significantly increased in Taekwon-Do(p <0.005). 4. The BMD of right and left legs were 1.597 ± 0.153 0.118 and 1.579 ± 0.153 0.125 in Taekwon-Do and 1.425 ± 0.153 0.115 and 1.421 ± 0.153 0.113 in control group respectively. They were significantly increased in Taekwon-Do(p <0.005). 5. The BMD of right and left arms were 1.184 ± 0.153 0.090 and 1.178 ± 0.153 0.115 in Taekwon-Do and 1.056 ± 0.153 0.095 and 1.066 ± 0.153 0.097 in control group respectively. They were significantly increased in Taekwon-Do(p.<0.005). 6. The total body BMD was 0.932 ± 0.153 0.068 in Taekwon-Do and 0.846 ± 0.065 in control. It is significantly increased in Taekwon-Do(p<0.005). In conclusion, Taekwon-Do increases the total bone mineral density and the mineral densities of the head, pelvis and extremities but not that of trunk. It is thought that continued practice of Taekwon-Do throughout adult life might prevent the senile osteoporosis

In children, the supracondylar fractures of the humerus are common in elbow region, and often associated with various complications and problems in treatment (ie,Volkmann's ischemic contracture, cubitus valgus or varus deformity, rotational deformity). The results of reduction can be measured by Baumann's angle, carrying angle, trochlea-capitellum angle, and displacement of distal radial styloid process on radiological study. So we have made experiments on the process which various three dimensional displacements reflected into two dimensional Baumann's angle and humerocapitellar angle. And we investigated the process of rotation, through various radiological studies by means of molded models of humerus. The results were as follows:l. In experiments, AP & lateral X-ray studies showed no change in rotation of proximal segment of fracture with fixed distal segment of fracture. 2. On the other hand, AP & lateral X-ray showed significant change, in rotation of proximal fracture segment with distal segment of fracture. 3. Supracondylar rotation angle(S.R.A.)depicted as the ratio of the length of proximal fracture width minus that of the distal fracture width in lateral view, to the length of distal fracture width in AP view minus that of the distal fracture width in lateral view. 4. According to the modified Mitchell result, S.R.A. to the result of treatment was average 7.6 degree in excellent group, 15.2 degree in good group and 29.3 degree in unsatisfactory group.

Endometriosis is an enigmatic disease of menstruating females affecting the reproductive life. We report herein a case of perineal endometriosis in a 33-year-old woman. The patient presented two rounded, thickened plaques bilaterally on the perineum for about four year. The plaque on the right side was located mainly at the episiotomy scar. Histologic examination showed confirmative feature of glandular structures embedded in the cellular stroma and predecidual changes of late secretory phase of endometrium. Radical operation of total hysterectomy with bilateral oophorectomy and partial excision of perineal lesions were performed. There was complete resolution with no relapse by the 6-month follow-up. This is of a very rare occurrence and three cases have been reported in the Korean literatures up to date.
