PURPOSE: We analyzed the correlation of the Lysholm score, anterior displacement of tibia on stress radiography and muscle strength around the knee with postural control after anterior cruciate ligament reconstruction and also compared them with the normal subjects. MATERIALS AND METHODS: Twenty-five patients after ACL reconstruction were evaluated with Lysholm knee score, anterior displacement on stress radiography with Telos, muscle strength around the knee with Biodex dynamometer and postural control with posturography. RESULTS: The postural control had significant correlation with the Lysholm knee score & anterior displacement on stress radiography(r=0.565, r=0.783, p<0.01), but not with muscle strength around the knee(p>0.05). Patients group with 5mm instability under anterior displacement on stress radiography showed no significance compared with normal control group, while the group with instability more than 6mm showed significant differences in some conditions com- pared with control group. CONCLUSION: Postural control after ACL reconstruction have significant correlation with Lysholm score and we presumed that the acquisition of mechanical stability of the knee after ACL reconstruction may be one of the important factors associated with the recovery of postural control by improvement of the proprioception.

PURPOSE: This research was conducted to examine the relationship of knowledge, health beliefs, and self-efficacy on osteoporosis. METHOD: The design of this study was a correlative design. The subjects were 1,615 Korean adults over the age of 20 registered in a new town and participants were asked to fill in a questionnaire developed by Kim, Horan & Gendler (1991), translated into Korean. RESULTS: 1) The subjects recorded an average score of 11.10 on osteoporosis knowledge. The average scores on the osteoporosis health beliefs was 15.68 for perceived susceptibility and the respondents recorded an average score of 40.40 for osteoporosis self-efficacy. 2) There were statistically significant differences in the degree of osteoporosis knowledge, self-efficacy and health belief according to gender, age, scholastic achievement, marital state, and jobs. 3) There were statistically significant positive correlations between osteoporosis knowledge and self-efficacy. CONCLUSION: According to these results, an osteoporosis education program improving not only knowledge but also self-efficacy and health beliefs should be developed and applied to decrease the perception of barriers to exercise and intake of calcium.

BACKGROUND: Patency of the infarct-related coronary artery may influence LV remodeling, provide a more stable electrophysiologic milieu and improves the outcome of patient with acute myocardioal infarction. The result from clinical trials have confirmed that early reperfusion in humans induced by a thrombolytic agent is associated with limitation of infarct size, preservation of ventricular function, and improved survival. The purpose of this study was evaluate the effect of thrombolytic therapy on the severity of the residual stenosis, antegrade flow of infarct-related coronary artery after acute myocardial infarction, and investigate left ventricular function and regianal wall motion abnormality depending on the thrombolytic therapy. METHODS: A retrosperctive study was performed in 166 patients with acute myocardial infarction with underwent coronary angiography within 8 days after acute attack from Oct. 1990 to Sep. 1994. Patients were grouped as thrombolysis group(n=64) who had undertaken urokinase infusion therapy within 6 hours of symptom onset and conservatively treated group(n=102) who had not received thrombolytic trerapy. At 8+/-7days, cardiac catheterization was performed. Status of the infarct related artery was assessed by resiudal % diameter stenosis, TIMI and collateral trading. Left ventricular function and wall motion were analyzed. RESULTS: 1) The was no statistical differenccs in age, sex and risk factors(diabetes, hypertension, smoking and hypercholesterolemia)between two groups. 2) The peak serum CK level was higher(2719+/-2333 vs 1951+/-2064 IU/L) and time to peak CK enzyme level was shorter(19+/-13 vs 32+/-24 hr) in thrombolysis group than conservatively treated group. 3) There was lower incidence of total occlusion(12.5% vs 30.4%), residual % diameter stenosis of infarct-related artery(67+/-34% vs 80+/-27%) and better antegrade flow(TIMI grade 0-1, 12.5% vs 32.4%) in thrombolysis group than conservatively treated group(p<0.05). 4) There were no statistical differences of ejection fraction(51+/-15 vs 51+/-14%). left ventricular end diastolic pressure(21+/-10 vs 21+/-16mmHg) and regional wall motion score(8.6+/-3.4 vs 9.1+/-3.1) between thrombolysis group and conservatively treated group(p>0.05). CONCLUSION: Thrombolytic therapy in acute myocardial infarction resulted in dquisition of early infarct-related arterial patency, effectiove antegrade flow and reduced incidence of totoal occlusion of infarct-related artery. Left ventricular ejection fraciton, regional wall motion score was not affected by thrombolytioc therapy in inhospital period.

PURPOSE: To determine the risk factors and incidence of cataract formation over a long-term mean follow-up of 7.5 years after type V4 implantable collamer lens (ICL) implantation. METHODS: We analyzed the preoperative, 3-month postoperative, 3-year postoperative, and last follow-up data of 228 eyes (118 patients) with mean preoperative spherical equivalent of -12.7 D and minimum postoperative follow-up of 3 years. Additionally, we determined the risk factors for cataract formation and calculated the 10.3 year cumulative cataract formation rate and 10.3 year cumulative cataract surgery rate using a survival curve. RESULTS: After type V4 ICL implantation with minimum follow-up of 3 years, the calculated 10.3 year cumulative cataract formation rate was 20% and actual cataracts developed in 34 eyes (14.9%). The 10.3 year cumulative cataract surgery rate was 12% based on a survival curve and actual cataract surgery was performed in 12 eyes (5.3%). The risk factors for cataract formation were age (odds ratio [OR] = 1.10, p = 0.00), preoperative spherical equivalent (OR = 0.90, p = 0.00), crystalline lens thickness (OR = 9.54, p = 0.00), axial length (OR = 1.33, p = 0.00), 3 months postoperative vault (OR = 0.50, p = 0.03), and existence of peripheral touch between ICL optic margin and crystalline lens at last follow-up (OR = 7.84, p = 0.00). CONCLUSIONS: We suggest one of the main risk factors for cataract formation after ICL implantation is decreased central vault and peripheral touch between ICL optic margin and crystalline lens.

The nfa1 gene was cloned from a cDNA library of pathogenic Naegleria fowleri by immunoscreening; it consisted of 360 bp and produced a 13.1 kDa recombinant protein (rNfa1) that showed the pseudopodia-specific localization by immunocytochemistry in the previous study. Based on the idea that the pseudopodia-specific Nfa1 protein mentioned above seems to be involved in the pathogenicity of N. fowleri, we observed the effect of an anti-Nfa1 antibody on the proliferation of N. fowleri trophozoites and the cytotoxicity of N. fowleri trophozoites on the target cells. The proliferation of N. fowleri trophozoites was inhibited after being treated with an anti-Nfa1 polyclonal antibody in a dose-dependent manner for 48 hrs. By a light microscope, CHO cells co-cultured with N. fowleri trophozoites (group I) for 48 hrs showed severe morphological destruction. On the contrary, CHO cells co-cultured with N. fowleri trophozoites and anti-Nfa1 polyclonal antibody (1: 100 dilution) (group II) showed less destruction. In the LDH release assay results, group I showed 50.6% cytotoxicity, and group II showed 39.3%. Consequently, addition of an anti-Nfa1 polyclonal antibody produced a decreasing effect of in vitro cytotoxicity of N. fowleri in a dosedependent manner.

PURPOSE: The objective of this work is to determine whether the degree of expression of Human Erythrocyte Glucose Transporter (Glut-1) protein might correlate with survival rate, tumor stage and pathologic findings in renal cell carcinoma (RCC). MATERIALS AND METHODS: 94 patients who underwent radical nephrectomy at our department for RCC were included in this retrospective study. Biologic significance of Glut-1 immunohistochemical staining according to the survival rate, tumor stage and pathologic findings in patients with RCC was evaluated. Immunohistochemical staining was performed using a primary antibody which was polyclonal rabbit anti-human Glut-1. RESULTS: In 67 of 94 patients, Glut-1 staining was demonstrated in the plasma membrane of cancer cells. Positive staining of Glut-1 in clear cell type was significantly higher than chromophobe type and chromophill type (p=0.01, 0.04). Positive staining for Glut-1 did not show any significant difference between localized and metastatic RCC. Positive staining for Glut-1 did not show any significant difference with tumor stage (p=0.09) or nuclear grade (p=0.20) or survival rate in localized RCC. CONCLUSIONS: In summary, Glut-1 protein express not in the normal portion of kidney but in the RCC. Expression of Glut-1 protein does not correlate with tumor stage, nuclear grade, or survival rate. These findings suggest that RCC may have another type of glucose transporter.

PURPOSE: Recently, Geneticin (G418) were known to exert neuroprotective effects in the hypoxic-ischemic (H-I) brain injury, but the mechanism is still unclear. The roles of fibroblast growth factor (FGF) and FGF receptor (FGFR) ware not well known in the H-I brain injury. We investigated the neuroprotective effects of systemically administrated Geneticin through the regulation of FGFR following the H-I brain injury METHODS: The cortical neuron cell culture of Spague-Dawley (SD) rat embryo brain (E18) was done in a hypoxic incubator. The cultured cells were divided three groups: a normoxia group, a hypoxia group, and an Geneticin-treated group. After verifying the desired amount of cellular injury in the hypoxia group, the Geneticin-treated group (after an H-I insult) was further divided into two groups. This produced four final groups: normoxia, hypoxia, and Geneticin-treated groups before H-I insult and a Geneticin-treated group after HI insult. The expression of FGFR-2 and FGFR-3 mRNA was measured using Northern blotting. RESULTS: The expression of FGFR-2 and FGFR-3 mRNA was notably increased in the hypoxic group compared to the normoxic group. In both Geneticin-treated groups before and after a hypoxic insult, the expression of FGFR-2 and FGFR-3 mRNA was decreased. CONCLUSION: It suggests that FGFR has an important role in hypoxic brain injury. Geneticin appears to exert a protective effect through down regulation of the expression of FGFR mRNA. However, more experiments are needed in order to demonstrate the usefulness of Geneticin as a preventative and rescue treatment for H-I brain injuries of neonatal brain.
