Purpose: To evaluate the clinical and radiographic results of primary bipolar arthroplasty during average 9.8-year period, using a non-cemented Multilock femoral stem and a biarticular acetabular cup. Materials and Methods: This study included 24 patients (29 hips) who underwent primary bipolar hemiarthroplasties with Multilock femoral stems and biarticular cups and who could be followed for more than seven years. Clinically, we evaluated the Harris Hip scores and patient complaints of thigh and inguinal pain. We also evaluated the radiographic measurements around the femoral stems and the bipolar cups. Results: The average Harris Hip score improved from 57.4 points to 91.6 points; and 3 (10.3%) hips were associated with thigh pain and 4 (13.8%) hips with inguinal pain. Around the femoral stem there was a non-progressive radiolucent line less than 1 mm in length in 4 (13.8%) hips and osteolysis was present in 6 (20.6%) hips. With respect to the stability of the fixations, there was osseous ingrowth in 26 (89.7%) hips and fibrous ingrowth in 3 (10.3%) hips. Around the acetabulum there was osteolysis in 5 (17.2%) hips, proximal migration of the cup in 2 (6.9%) hips, and erosion of the acetabular cartilage in 10 (34.5%) hips. There were 3 (10.3%) biarticular cups, which were converted to total hip arthroplasties, but no femoral stems were revised. The overall failure rate of the primary operations was 10.3%. Conclusion: The current study demonstrated favorable results after bipolar hemiarthroplasties with Multilock femoral stems. However, the osteolysis that occurred around the femoral stems and the acetabula emerged as a problem after the total hip arthroplasties. In particular, it is expected that the osteolysis would increase over time and become the main cause for the need for surgical revision.

In order to investigate the efficacy and safety of oral fosinopril, a new phosphorus containing angiotensin converting enzyme inhibitor, a single dose of 10 to 20mg was administered in 23 hypertensive patients with diastotic blood pressure above 95mmHg and all other anti-hypertensive agents were not administered during 4 weeks of study. Blood pressure and heart rate were measured on the 2nd and 4th week of therapy. The complete blood count with platelet count, blood chemistry by SMA-12 and serum electrolytes were performed at the begining and 4th week of therapy. The urinalysis and electrocardiography were performed at the beginning and 4th week of therapy. Any kinds of side effects were actively questioned by the examining physicians. The following results were obtained : 1) At the beginning and 4th weeks of therapy, the average systolic and diastolic pressure were 170.0+/-17.6/101.6+/-6.1mmHg, 142.7+/-15.1/87.3+/-6.7mmHg respectively. The systolic and diastolic blood pressure were declined statistically significantly(p<0.05) throughout the period of treatment and diastolic blood pressure of all subjects except 3 patients(86%) was maintained below 90mmHg after 4th week of treatment. 2) There was no significant change in the pulse rate before and after therapy. 3) There were no significant changes in blood chemistry, serum electrolytes, hematologic findings, urinalysis and electrocardiographic findigns. 4) side effect were developed in 5 patients(23%) with dry cough, 3 patients(13%) with headache and 2 patients with facial edema but side effects were mostly mild in nature without potenitally serious episodes. These results suggested that antihypertensive therapy with onec-daily fosinopril was effective and well tolerated in essential hypertensive patients.

PURPOSE: We measured serum lycopene concentration and compared it in normal subjects, normal tension glaucoma (NTG), primary open angle glaucoma (POAG) patients. METHODS: We investigated serum lycopene concentration on 226 subjects, which were divided into 3 groups : group 1 with 136 normal subjects, group 2 with 24 NTG patients, group 3 with 66 POAG patients. Serum concentration of lycopene was measured by high performance liquid chromatography (HPLC). RESULTS: Mean age was 64.1+/-9.2 years old in group 1, 56.4+/-1.2 years old in group 2, 53.8+/-5.3 years old in group 3. Sex ratio (male:female) was 1:1 in group 1, 1.18:1 in group 2, 0.94:1 in group 3 respectively. Serum lycopene concentration was 6.44+/-0.34 microgram/dl in group 1, 2.55+/-0.44 microgram /dl in group 2, 2.17+/-0.27 microgram /dl in group 3 respectively. CONCLUSIONS: Serum lycopene concentration was significantly lower in NTG, POAG patients than normal subjects (P<.05). Further nutritional survey is necessary for new modality of treatment of glaucoma.

Granular cell tumor is characterized by large eosinophilic cells with granular appearances. These are mostly benign. Approximately 1~2% are malignant, and establishment of reliable criteria for diagnosing malignant granular cell tumor has been difficult to establish because of the rarity. Reports on the cytologic features of this neoplasm are hardly found in Korea. We report a case of rarely-occurring granular cell tumor in the lower leg of a 40-year-old male, diagnosed on fine needle aspiration cytology, together with a review of the literature regarding significant adverse histology and prognostic factors. The aspirates revealed cellular smears of isolated cells, syncytial clusters, and occasionally stripped nuclei in a fine, bluish-purple, granular background. Tumor cells were polygonal, rounded, or slightly spindled, and showed ill-defined granular cytoplasm. Nuclei were small and round or oval, with inconspicuous or small, prominent nucleoli. The nuclei showed rare intranuclear cytoplasmic invagination. Occasionally, there were mild to moderate nuclear pleomorphisms with vesicular nuclei, with large, prominent nucleoi, but no mitosis. The immunocytochemical stain for S-100 was strongly positive in the cytoplasm of tumor cells with occasional nuclei.

In order to study the implantation mechanism various methods for culture of endometrial cells in vitro have been attempted. However, a disadvantage is that primary cultures of stromal and epithelial cells do not have the ability to differentiate, and therefore cannot be reproduced in the same manner as in vivo endometrium. The object of this study is to establish a three dimensional culture of endometrial cells which are both morphologically and functionally identical to in vivo endometrium. Endometrial tissues obtained after hysterectomies were cut into thin slices and treated with collagenase and trypsin-EDTA. The stromal cells and the epithelial cells were separated by centrifugation and cultured for 24 hours in DMEM media containing 10% FCS, 100 nM progesterone, and 1 nM estradiol. The cultured stromal cells were mixed with collagen gel and solidified, after which it was covered with matrigel. Epithelial cells were inoculated on the top and then cultured for 3 days. The three dimensionally cultured endometrial cells were stained for integrin alphal, alpha4, beta3, and cyclooxygenase-1, -2 by immunohistochemistry, which all showed strong expression. The cultured epithelial cells showed the formation of microvilli, tight junctions and pinopodes by electron microscopy. Studies are currently under way utilizing this three dimensional culture model to ascertain the interaction between the embryo and human endometrial cells at the time of implantation, and it is thought that further studied into a new culture environment which would allow longer periods of culture will be necessary.

PURPOSE: To determine the levels of antioxidant minerals in serum of normal subjects and patients with cataract. METHODS: Concentrations of antioxidant minerals such as selenium, manganese, copper, zinc were measured with atomic absorption spectrophotometer (AAS) 4110ZL in serum of 45 normal subjects (group 1) and 34 patients (group 2) with cataract, and Cu/Zn ratio was calculated. RESULTS: Serum concentrations of copper were 108.9 +/- 5.48 (male) and 106.9 +/- 5.25 microgram/dl (female) in group 1, 100.9 +/- 5.87 (male), 105.6 +/- 3.68 microgram/dl (female) in group 2, respectively. For zinc they were 105.8 +/- 7.33 (male) and 103.7 +/- 4.24 microgram/dl (female) in group 1, 80.0 +/- 5.78 (male) and 95.1 +/- 6.18 microgram/dl (female) in group 2, respectively. Zn/Cu ratio were 0.98 +/- 0.02 (male) and 1.05 +/- 0.08 (female) in group 1, 1.58 +/- 0.29 (male) and 1.19 +/- 0.09 (female) in group 2, respectively. CONCLUSIONS: Serum zinc concentration in male was significantly lower in cataract patients than in normal subjects (p<0.01). Cu/Zn ratio was lower in cataract patients than in normal subjects in male, but not in female. Further nutrional survey is necessary to determine the relationship between level of antioxidant minerals and development and progression of cataract.

Background/Aims: Biliary strictures remain one of the most challenging aspects after living donor liver transplantation (LDLT). The aim of this study was to assess long-term outcome of endoscopic treatment of biliary strictures occurring after LDLT and to identify risk factors of recurrent biliary strictures following endoscopic retrograde biliary drainage (ERBD) in LDLT. Methods: A total of 1,106 patients underwent LDLT from May 1995 to May 2014. We compared the risk factors between patients with and without recurrent biliary strictures. Results: Biliary strictures developed in 24.0% of patients. Technical success rate of ERBD for biliary stricture after LDLT was 66.2% (145/219). Among 145 patients managed by endoscopic drainage, stricture resolution occurred in 69 with median duration of stent indwelling of 13.6 months (range, 0.5 to 67.3 months), and stricture recurrence was seen in 20 (21.3%) out of 94. The median recurrence-free duration after final endoscopic success was 13.1 months (range, 0.5 to 67.3 months). Older donor age (hazard ratio [HR], 1.10; 95% confidence interval [CI], 1.03 to 1.17; p=0.004) and non-B, non-C liver cirrhosis (HR, 5.10; 95% CI, 1.10 to 25.00; p=0.043) were associated with higher recurrence of biliary stricture. Conclusions Long-term stricture resolution rate after ERBD insertion for biliary stricture occurring after LDLT was 73.4%. Clinicians should pay careful attention during following-up to decide when to remove ERBD in patients who have factors associated with recurrent biliary strictures.
