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.

BACKGROUND: The chemiluminescent assay(CLA) is a new in vitro non-radioactive modification of the radioallergosorbent test(RAST). The CLA permits quick, siultaneous detection of total and specific IgE in human serum up to 35 different allergens, as well as their semiquantitative concentrations into classes from 0(negative) to 4(very high). The CLA has shown sensitivity, specificity, and a good correlation with the RAST and also with skin pick testing. OBJECTIVE: The purpose of this study was to find the causatix llergens and to evaluate the clinical significance of CLA comparing the results of tbe CLA wi! h hose of the prick test in patients with chronic urticaria. METHODS: We performed the CLA with 35 allergens(MAST immunosunosystems, Inc., California, America) and the prick test with 51 allergens(Bencard Ltd., Bricantord, England) in 70 patients with chronic urticaria. The CLA detects the allergen-IgE reactic say the use of an enzyme-labeled anti-IgE and a coupled photoreagent mixture. lhe amount of the luminescent energy is measured by exposing a polarcid film and then semiquantitation is a sessed by using a densitometer. RESULTS: Except for those over the age of 60, all age-groups ealed a similar positive reaction to the CLA and prick test, but the positive reaction rate o the prick test(91.4%) was higher than that of the CLA(38.6%). The positive reaction rate oringle allergen and compound allergens was 10.0% and 28.6% in the CLA, but 10.0% and 81.4% in the prick test, respectively. In the CLA, the rate of positive reaction was 17(24.3%) in Dermatophagoides(D.) farinae, 15(21.4% ) in D. pteronyssinus, 5(7.1% ) in house dust, an 13(4.3%) in shrimp in that order. In the prick test, the rate of positive reaction was 39(55.7%) in house dust, 35(50.0%) in D. farinae, 29(41.4%) in D. pteronyssinus, and 21(30.0%) in haydrst(30.0%) in that order. The results of the CLA to 3 comrnon allergens showed a concordance rare of 67.6%, sensitivity of 34.3%, and specificity of 97.3% compared with those of the prick case. The levels of total IgE and eosinophils were elevated in 59(n=70, 843%) and in 5(n=56, 84.3%), respectively. CONCLUSION: The results of this study suggest that the CLA may be used as an alternative method for the diagnosis of chronic urticaria because it is and coiomic, safe, simple procedure with very high specificity and trelative low sensitivity, and is sirnilt. neously capable of testing to multiple allergens.

Ki-1 antigen was found by a monoclonal antibody, made against a Hidgkin' disease-derived cell line (L428) that reacted with Reed-Sternberg cells in Hodgkins disease and a few lymphocytes around lymphoid follicle. In 1985, Stein et al identified a large cell anaplastic lymphoma showing a distinctive pleomorphic appearance, sinus growth pattern, and reactivity to Ki-l. We report a case of Ki-1 positive large cell anaplastic lymphoma, which was presenting as a elevated plaque on the skin of popliteal fossa in a 69-year-old female.

Breast cancer is the second leading cause of cancer death in women. Unfortunately, the frequency of breast cancer and mastectomy are increasing in Korea. The purpose of the study is to analyze the results of breast reconstruction using free transverse rectus abdominis myocutaneous(TRAM) flap and to suggest the operative technique for more satisfactory results. 19 patients underwent immediate breast reconstruction from 1990 to 1998, and we experienced 2 cases of bilateral immediate reconstruction of breasts following mastectomy. We have performed the free TRAM flaps based on the deep inferior epigastric vessels using microvascular technique. TRAM flap included very small portion of rectus sheath and muscle-so called muscle sparing technique. So it reduced markedly donor site morbidity. The postoperative course of these cases was uneventful with minor complication. The free TRAM flap was an excellent method of immediate breast reconstruction using autogenous tissue and provided satisfactory outcome. The goals of the immediate breast reconstruction after mastectomy are to restore body image, to achieve near normal shape of breast, and to reduce the complications. This paper represents our experience of immediate breast reconstruction using free TRAM flap, and technical options to get more satisfactory result and reduce the complications. We think this method could be regarded as the first choice for immediate breast reconstruction.

OBJECTIVE: To assess the association with autoimmune endocrine diseases and detection rate of autoimmune antibodies and its clinical significance in patients with premature ovarian failure. METHODS: Twenty eight patients with primary or secondary amenorrhea manifesting hormonal and clinical features of premature ovarian failure (primary POF: 7, secondary POF: 21) were investigated. We tested them TFT, 75 g OGTT, ACTH and S-cortisol for thyroiditis, IDDM, Addison's disease, and antithyoglobulin antibody, antimicrosomal antibody, antinuclear antibody, rheumatic factor, anti-smooth muscle antibody, anti-acetylcholine receptor antibody for non-organ specific autoimmune disorders. RESULTS: Only one patient was diagnosed as IDDM and no patients had abnormal TFT or adrenal function test. More than one kind of autoantibody was detected in 11 patients of all (39.2%): 5 patients (71.4%) of primary POF group and 6 patients (21.4%) of secondary POF group. Eleven patients (39.3%) had antithyroglobulin antibody, 4 (14.3%) had antimicrosomal antibody, 2 (7.1%) had antinuclear antibody, 2 (7.1%) had rheumatic factor, 1 (3.6%) had anti-smooth muscle antibody, 1 (3.6%) had anti-acetylcholine receptor antibody. CONCLUSIONS: Premature ovarian failure may occur as a component of an autoimmune polyglandular syndrome, so patients should be measured with free thyroxine, thyroid-stimulating hormone, fasting glucose and electrolytes. Measurement of thyroid autoantibodies in POF patients may be important in identifying patients at risk of developing overt hypothyoidism, but other autoantibodies may not be suitable for screening test.

PURPOSE: Penile size has been a focus of interest in the life and the culture throughout human history. It has been a longstanding question whether there is any relation between penile size and the dimensions of body extremities. We measured the standard length of the penis and investigate whether any body extremity is a predictive index of penile size in Korea men. PATIENTS AND METHODS: A series of 655 males above 17 years of age were examined during a 4-month period. Stretched penile length, penile circumference, and length and characteristics of various body parts and features (1st finger, 2nd finger, 3rd finger, 1st toe, 2nd toe, 3rd toe, ear, mouth, nose, height, weight, and baldness) were investigated by one examiner. To see the relation among the penile length and circumference and various body dimensions, univariate and multivariate statistical methods such as correlation analysis and multiple linear regression were applied. RESULTS: The mean values standard deviations were 46.6 +/- 18.4 for age, 10.0 +/- 2.0 cm for the length of the penis, and 8.5 +/- 1.0 cm for the circumference of the penis. In a correlation coefficient analysis, the length of the penis was slightly correlated with penile circumference. Additionally, the circumference of the penis was slightly correlated with penile length, patient height, weight, and 3rd toe and 1st toe length, in decreasing order. In a multivariate analysis, the coefficients of determination from multiple linear regression were 13% and 15% for the length and the circumferences of the penis, respectively. CONCLUSIONS: Human body index including the size or characteristics of body extremities is not enough to predict the penile size.

Clonidine, an 2 agonist, has been shown to be effective as preanesthetic medication in adults. To evaluate the effects of clonidine on the sedation and cardiovascular changes induced by intubation, we administered clonidine (2.0-2.5g/kg, 4.5-5.0g/kg, peros) 90-120min before induction of anesthesia. We measured heart rate, systolic pressure and diastolic pressure before premedication, before induction, after intubation and 5, 10, 15, 20 and 30 min after intubation and evaiuated sedative sction before induction. The results are as follows: 1) Before intubation heart rate decreased significantly in both clonidine groups compared with diazepam group (P<0.05). 2) Before intubation clonidine 4.5-5.0g/kg group produced a significant reduction in systolic pressure compared with diazepam group (P<0.05). 3) After intubation systolic and diastolic blood pressure increased in all group but the increasing rate was significently less then in clonidine 4.5-5.0g/kg group (P<0.05). 4) After intubstion the increase in heart rate in both clonidine groups were significsntly less than in diazepam group (P<0.005). 5) Sedative actions were not significantly different in all groups.

Intracranial dermoid cyst is a rare congenital benign disease, representing less than 0.5% of primary brain tumors. Nevertheless, if ruptured spontaneously or during surgery, it has a poor prognosis due to chemical meningitis. Therefore, it is essential to perform accurate diagnosis and proper treatment. We report an intracranial subdural dermoid cyst that may be misdiagnosed as extracranial or epidural lesion because of extension into the right foramen ovale, and describe the CT and MR imaging findings.
