PURPOSE: This is to evaluate the clinical results and radiologic changes of the mandibular condyle fractures following the open reduction and fixation using the Lag-screws introduced by Eckelt and Martin Co. MATERIALS & METHODS: Ten patients who had been treated by the Lag-screw fixation for the unilateral fracture of the mandibular condyle at the high level and followed up for over 6 months(ranged from 24 weeks to 33 weeks). The incisal opening by time elapsed, displacement of the fragments, bone resorption around the Lag-screws, operating time consumed, and untoward complications were evaluated. The data were tested by repeated measure ANOVA and paired t-test. RESULTS: The maximum mouth opening was increased by time as follows ; 20.2+/-2.8mm soon after reduction. 26.3+/-3.9 at the 2nd week, 37.7+/-4.2mm at the 4th week, 44.4+/-4.3mm in PO 2 months(P<0.05). The bone resorption at anterior to lag-screw nut was measured to 1.9+/-1.0mm, while the posterior resorption was 2.6+/-1.9mm on average(P<0.05). Reduction and fixation of the fragments by Lag-screw were done within 80 minutes including the skin closure. The clicking sound of the TMJ(40%), weakness of the marginal branch(60%) were complicated but transient for 4-8weeks. There were no signs of bony displacement, but loosening of screws were observed at the time of removal. CONCLUSION: Open reduction and fixation with condylar Lag-screw(Martin co., Germany) thru the ramus can be a good option to reduce the high level(Kruger's Level III & IV) fracture of the mandibular condyle with anterior or medial displacement. However, this procedure requires 2nd surgery to remove the devices and it may complicate improper reduction for delayed fractures and in case of 's' curved mandibular ramus.

Vibrio parahaemolyticus is a gram-negative halophilic organism commonly associated with outbreaks of acute gastroenteritis which also sometimes causes serious wound infection. It is an uncommon cause of bacteremia. We have experienced a case of bacteremia due to Vibrio parahaemolyticus in a 59-year old man who initially presented with edema and dyspnea. He was diagnosed as liver cirrhosis, gastric cancer, and hepatoma. On hospital day 13, Vibrio parahaemolyticus was isolated from blood culture. The isolate showed typical cultural and biochemical characteristics such as salt tolerance and did not ferment lactose. The isolate was intermediate to ampicillin but susceptible to other agents.

BACKGROUND AND OBJECTIVES: There is little clinical data on the results of using Sirolimus-Eluting Stent (SES) for treating In-Stent Restenosis (ISR). We performed this study to evaluate the clinical outcomes for implanting SES for treating ISR in a real world hospital environment. SUBJECTS AND METHODS: A total of 30 patients with 32 ISRs (males: 73.3%, mean age: 60.2) (focal lesions: 21.9%, diffuse intra-stent lesions: 34.4%, proliferative lesions: 21.9%, total occlusions: 21.9%) were treated with SES after balloon predilation was performed. We evaluated the clinical results and the performed coronary angiography after 6 months. RESULTS: All the procedures were successful. The mean SES diameter and length were 3.0+/-0.3 mm and 27.1+/-5.5 mm, respectively, and the mean acute gain was 2.42+/-0.38 mm. No in-hospital major adverse cardiac events (MACE) were observed. Twenty five patients with 27 lesions (84.4%) underwent coronary angiography at their 6 month follow-up. The late loss and loss index were 0.41+/-0.56 mm and 0.18+/-0.22, respectively. The binary restenosis rate was 7.4% (2/27 lesions). The rate of target lesion revascularization was 3.7% (1/27 lesion). The incidence of MACE at 6 months was 3.3% (1/30 patient). CONCLUSION: Treating ISR with SES is a safe and effective procedure for reducing ISR without the occurrence of acute or sub-acute thrombosis.

6.The Clinical Features of Geriatric Ocular Trauma in a Regional Emergency Medical Center.
Journal of the Korean Geriatrics Society 2013;17(4):192-197
BACKGROUND: The development of the medicine and the rise in the expectation of living has led the Korea into an aging society and the senior population in the Korea continues to grow. The objective of this study is to investigate the clinical features of geriatric ocular trauma in in a regional emergency medical center. METHODS: We retrospectively reviewed the medical records of 163 eyes of 146 patients older than 65 with ocular trauma who visited Emergency Room of Dongguk University Gyeongju Hospital from March 1, 2007 to February 29, 2012. RESULTS: In all patients, the incidence of the geriatric ocular trauma in patients over 65 was 7.3% (146 patients). And it was found to be 2.4 times more common in males (103 patients, 70.5%) than it was in females (43 patients, 29.5%). The mean age of patients was 70.7 years. Geriatric ocular trauma occurred mostly in the summer and the most common place of occurrence was the streets. Traffic accidents were the most common reason (35 patients, 24%) and the most common form of ocular trauma was the corneal erosion (42 patients, 21.1%). CONCLUSION: Through this study we found out the characteristics and the tendency of geriatric ocular trauma. And these results can be helpful in the prevention of geriatric ocular trauma and the improvement on treatment of geriatric ocular trauma.

7.The Effect of Transfer of p21/WAF1 Gene on Kidney and Bladder Cancer Cell Lines.
Korean Journal of Urology 1999;40(2):175-186
PURPOSE: To identify antitumor effect, indication and antitumor mechanism of p21/WAF1 gene therapy in human kidney and bladder cancer. MATERIALS AND METHODS: We cloned cDNA of wild type human p21 gene by reverse transcription-polymerase chain reaction(RT-PCR) technology and constructed a mammalian expression plasmid vector carrying cDNA of wild type human p21 and CMV enhancer/promotor(pCMV-p21). pCMV-p21 was administered in vitro in complex with HDL cationic polyliposome into human kidney cancer cells(CURC-1 and CURC-2), bladder cancer cells(RT4 and T24), and liver cancer cells(Hep3B and HepG2), followed by analysis of viable cell number, cellular morphology, cell cycle distribution and development of apoptosis. RESULTS: The expression of p21 was preserved in p53-wild type cells and markedly decreased or absent in p53-mutant cells. Administration of pCMV-p21:HDL complex induced high level expression of p21 and significant suppression of growth in all of the cancer cells examined, regardless of their genetic status of p21 and p53. Transfer of p21 to cancer cells induced not only decrease of proportion of cells in G2+M/S phase but also apoptosis. CONCLUSIONS: HDL cationic polyliposome-mediated p21 gene transfer may become a promising therapeutic modality for human kidney and bladder cancer and that p21 may have a novel function to induce apoptosis to human bladder and kidney cancer cells. Further studies are necessary on in vivo antitumor effect of p21 gene transfer and molecular mechanism of p21 gene-induced apoptosis.

Serum immunoglobulins from Israeli carp (I. carp) were purified using affinity chromatography. Fish were immunized with purified mouse IgG, and the specific fish antibodies purified from the immune serum on a mouse IgG-immobilized agarose gel. Rabbit anti-carp Ig (Raclg) antibodies were produced following hyperimmunization with mlgG specific I. Carp Ab. SDS-PAGE analysis under reducing condition showed that I. carp Ig (clg) were composed of two u-like heavy chains with about 82 and 50 kD, respectively and one light chain with about 25 kD. On immunoblotting analysis, however, Raclg failed to react with light chain. When both protein A and protein G purified normal clg were compared with mlgG specific clg, no significant structural differences among them were observed. To investigate if there is any homology between other fish Ig molecules, cross-reactivity of Raclg against Ig molecules from 6 different fish sera and mouse control serum was checked on immunoblotting analysis. As a result, Raclg responded to only carp and tilapia Ig molecules, indicating that both tilapia and carp are very closely associated, especially, in the genetic basis of immunoglobulin structure. In flow cytometry study, Raclg appeared to recognize 45.8% of carp Ig+, 14.5% of catfish Ig+ and <5% of tilapia Ig+ cells. The result suggest the heterogeniety between receptor immunoglobulins on B-like lymphocytes and soluble immunoglobulins in serum. It is crucial to obtain pure fish immunoglobulins to produce reagent antibodies as tools for the study of their specific immune response.

We investigated the effects of panretinal photocoagulation (PRP)on macular microcirculation in diabetic retinopathy. PRP using argon blue green laser was performed in 23 eyes of 15 patients with early proliferative diabetic etinopathy and very severe nonproliferative diabetic retinopathy without significant macular edema. The changes in volume, flow, velocity of macular microcirculation were measured before PRP, 1 hour, 1 day, 1 week, and 1 month following PRP, using Heidelberg Retina Flowmeter(HRF). Mean volume, flow, velocity of macular microcirculation decreased to a maximal degree 1 hour following PRP, from 14.87+/-0.40, 387.45 +/-101.40, 1.40+/-0.28(before PRP)to 12.44+/-1.39, 347. 33+/-100.39, 1.27+/-0.34(p<0.05). From 1hour to 1 month after PRP, macular microcirculation gradually increased. However, throughout this period, all parameters of macular microcirculation remained lower than pre-PRP level(p<0.05). Our study suggests that panretinal photocoagulation reduces the macular microcirculation in diabetic retinopathy.
