In order to evaluate the effects of a topical application of homologous fibronectin on the healing of skin wounds, we made 2 excisional wounds on the back skin of each rat, applied ointment with or without fibronectin purified from citrated homologous plasma, and evaluated the effect according to wound size and microscopic findings. Excised lesions treated with carrier alone, but the difference was significant only in the early phase of wound healing, 2 and 3 days, according to wound size and microscopic changes. A significant decrease in wound size could be found in both groups, treated with ointment containing and not containing fibronectin, between day 4 and 9 when wound contraction was a major contributor to wound closure. Therefore it can be concluded that topical application of fibronectin has a beneficial effect on wound healing during its early phase, but no significant influence on wound contraction.

BACKGROUND: Tumor markers have been used in diagnosis, predicting the extent of disease, monitering recurrence after therapy and prediction of prognosis. But the utility of markers in lung cancer has been limited by low sensitivity and specificity. TPA-M is recently developed marker using combined monoclonal antibody of Cytokeratin 8, 18, and 19. This study was conducted to evaluate the efficacy of new tumor marker, TPA-M by comparing the estabilished markers 8CC, CEA, Cyfra2 I - I in hmg cancer. METHODS: An immunoradiometric assay of serum CEA, SCC, Cyfra2l-I, and TPA-M was performed in 49 pathologically confirmed lung cancer patients who visited Keimyung University Hospital from April 1996 to August 1996, and 29 benign lung diseases. Commercially available kits, Ab bead CM (Eiken) to CEA, SCC RIA BEAD (DAINABOT) to SCC, CA21-1 (TEE) to Cyfra21-1, arid TPA-M (DAIICHI) to TPA-M were used for this study. RESULTS: The mean serum values of lung cancer group and control group were 10.05 +/- 38.39 micro/L, l.59+/-0.94 micro/L in CEA, 3.04+/-5.79 micro/L, 1.58+/-2.85 micro/L in SCC, 8.27+/-11.96 micro/L, 1.77+/-2.72 micro/L in Cyfra21-1, and 132.02+/-209.35 U/L, 45.86+/-75.86 U/t in TPA-M respectively. Serum values of Cyfra21-1 and TPA-M in lung cancer group were higher than control group (p<0.05). Using cutoff value recommended by the manufactures, that is 2.5 micro/L, in CEA, 3.0 micro/L in Cyfra21-1, 70.0 U/L in TPA-M, arid 2.0 micro/L in SCC, sensitivity and specificity of lung cancer were 33.3%, 786% in CEA, 50.0%, 89.7% in Cyfra2l-l, 52.3%, 89.7% in TPA-M, 23.8%, 89.3% in SCC. Sensitivity and specificity of nonsmall cell lung cancer were 36.1%, 78.1% in CIA, 50.1%, 89.7% in Cyfra2l-1, 53.1%, 89.7% in TPA-M, 33.8%, 89.3% in SCC. Sensitivity and specificity of small cell king cancer were 25.0%, 78.5% in CEA, 50.0%, 89.6% in Cyfra2l-1, 50.0%, 89.6% in TPA-M, 0%, 89.2% in SCC. Cutoff value according to ROC(Receiver operating characteristics) curve was l.25 micro/L in CEA, 1.5 micro/L in Cyfra2l-1, 35 U/L in TPA-M, 0.6 micro/L in SCC. With this cutoff value, sensitivity, specificity, accuracy and kappa index of Cyfra21-1 and TPA-M were Letter than CEA and SCC. SCC only was related with statistic significance to TNM stages, dividing to operable stages(TNM stage I to IIIA) and inoperable stages (IIIB and IV) (p<0.05). But no tumor markers showed any correlation with significance with tumor size(p>0.05). CONCLUSION: Serum TPA-M and Cyfra21-1 shows higher sensitivity and specificity than CEA and SCC in overall lung cancer and nonsmall cell lung cancer those were confirmed pathologically. SCC has higher specificity in nonsmall cell lung cancer. And the level of serum SCC are significantly related with TNM staging.

OBJECTIVES: People at ultra-high risk for psychosis have heterogenous character and different long-term outcomes. We divided ultra-high risk subjects into two subgroups by presence of familial history and tried to find different pattern of functional connectivity of the default mode network (DMN) between the two groups in order to examine the effects familial loading. METHODS: Eleven subjects at clinical-high risk (CHR) group with familial history of psychiatric illness and nineteen subjects of CHR group without familial history were recruited. All the subjects were scanned using resting-state functional magnetic resonance imaging. A posterior cingulate cortex was the seed region of the analysis, and the DMN of the both high risk group were analyzed with voxel-wise two sample T test. RESULTS: The CHR group with familial history showed greater functional connectivity in the precuneus area in contrast with the other high risk subjects (peak-level t=5.49, p<0.001). There were no significant differences in total score on the Positive and Negative Syndrome Scale and Scales of Psychosis-risk Syndrome between the two groups. CONCLUSION: The study suggests that the abnormalities of functional connectivity between precuneus and posterior cingulate area may be associated with the genetic vulnerability of high risk trait.

Bovine parainfluenza virus type 5 (bPIV5) was isolated from cattle with downer cow syndrome in 2012, and included both respiratory and neurotropic pathogens from a variety of animals. In the current study, we conducted serosurveillance using sera obtained from seven Korean farms and optimized a reverse transcription-polymerase chain reaction (RT-PCR) assay to detect bPIV5. The overall seropositive rate for Korean cattle was 21.4% (163/760). A farm located near the city of Milyang in Gyeoungnam province had a markedly elevated seropositive rate for bPIV5 compared to that of the other six farms. The regional seropositive rates were 4.2% (8/192) for Haman, 19.5% (18/55) for Hwasung, 73.9% (65/88) for Milyang, 26.0% (50/192) for Namwon, 1.0% (1/96) for Uljin, 13.5% (13/96) for Yeongju, and 32.7% (8/41) for Yongin. The sensitivity and specificity of three RT-PCR primer sets used to amplify the conserved fusion gene of bPIV5 were also evaluated. An RT-PCR assay using the bPIVFR3 primer set was 10-fold more sensitive than the assays using the two other primer sets and did not result in non-specific amplification. These results demonstrated that the bPIFR3 primer set can be used to detect bPIV5.

PURPOSE: To determine the changes of location of intraocular lens (IOL) and refractive errors in the cases of vitrectomized eyes and non-vitrectomized eyes, we evaluated the anterior chamber depth and refractive errors after phacoemulsification and posterior chamber IOL implantation. METHODS: In 21 vitrectomized eyes of 21 patients (group 1) and 22 non-vitrecomized eyes of 22 patients (group 2), the anterior chamber depth was measured with Orbscan II (Bausch and Lomb Surgical, Germany) for the evaluation of changes of anterior chamber depth preoperatively, at 1 month and 3 months postoperatively. We compared the desired refraction by preoperative data, and postoperative manifest refraction of postoperative 1 month and 3 months. RESULTS: In group 1, the anterior chamber was deeper than that of group 2 postoperative 1 month but the result was not statistically significant. After 3 months the chamber depth was significantly deeper in group 1 than group 2, (P=0.047), and refractive errors were significantly more hyperopic in group 1 than group 2. CONCLUSIONS: The vitreous influenced the location of IOL after phacoemulsification and posterior chamber IOL implantation, so in the cases of vitrectomized eyes IOL was more posteriorly located, and thus hyperopic shift was noted.

PURPOSE: As the Korean population ages, an increasing number of elderly patients with gastric cancer are undergoing surgical resection. The aim of this study was to analyze the surgical outcomes and prognostic factors after gastric cancer surgery for patients 80 years of age or older.METHODS: We analyzed the medical records of 720 patients with gastric cancer who underwent gastrectomy from March 2010 to December 2014 retrospectively. Patients were divided into two groups: octogenarians (age ≥80 years, n=46) and non-octogenarians (age <80 years, n=674). We evaluated clinicopathologic data including postoperative morbidity, mortality, and 5-year survival rate.RESULTS: The rate of curative resection was not different between the two groups. The American Society of Anesthesiology score was significantly higher in the octogenarians (P<0.05). Octogenarians exhibited poorer performance scale scores, higher comorbidities, and more advanced TNM stages than non-octogenarians. There was no difference in surgical resection margins between the two groups. In addition, octogenarians suffered from more postoperative morbidity and mortality than non-octogenarians. In the analysis of risk factors of survival after gastrectomy for octogenarians, advanced TNM stage and dose of transfusion were independent risk factors. Overall survival was significantly lower in octogenarians than non-octogenarians. There was no difference in the disease-specific survival for each stage of cancer after adjustment for tumor stage.CONCLUSION: Octogenarians had more preoperative risk factors and postoperative morbidity and mortality, but cancer-specific survival was comparable with non-octogenarians. Careful preoperative evaluation, thorough resection, and attentive postoperative care can improve the overall survival of octogenarians with gastric cancer.

Surgical resection is the most effective treatment in operable lung cancers. However, less invasive local treatments are being applicated to the patients having high surgical risk due to their poor general condition. Cryosurgery is known to be highly effective and safe in the treatment of liver and prostate cancers and it is also being applicated in the treatment of lung cancers, especially with the excision of tracheal mass and lung parenchymal cancers. In our hospital, we have tried a less invasive method, the cryotherapy, to a patient who had a newly developed lung cancer at his right lower lobe after he had been treated with right upper lobe resection and left upper lobe resection due to bilateral lung cancers. After the treatment, he is being followed up at our out patient department for 2 years. Here, we present the method and result that have been applicated in this case.

OBJECTIVE: The purpose of this study was to evaluate the fistulographic features of malfunctioning axillary loop-configured arteriovenous grafts and the efficacy of percutaneous interventions in failed axillary loop-configured arteriovenous grafts. MATERIALS AND METHODS: Ten patients with axillary loop-configured arteriovenous grafts were referred for evaluation of graft patency or upper arm swelling. Fistulography and percutaneous intervention, including thrombolysis, percutaneous transluminal angioplasty and stent placement, were performed. Statistical analysis of the procedure success rate and the primary and secondary patency rates was done. RESULTS: Four patients had graft related and subclavian venous stenosis, two patients had graft related stenosis and another four patients had subclavian venous stenosis only. Sixteen sessions of interventional procedures were performed in eight patients (average: 2 sessions / patient) until the end of follow-up. An interventional procedure was not done in two patients with central venous stenosis. The overall procedure success rate was 69% (11 of 16 sessions). The post-intervention primary and secondary patency rates were 50% and 63% at three months, 38% and 63% at six months and 25% and 63% at one year, respectively. CONCLUSION: Dysfunctional axillary loop-configured arteriovenous grafts almost always had subclavian venous and graft-related stenosis. Interventional treatments are helpful to overcome this and these treatments are expected to play a major role in restoring and maintaining the axillary loop-configured arteriovenous loop grafts.

OBJECTIVE: We evaluated the clinical characteristics and prognoses of patients with septic shock who transferred to the emergency department (ED) in a tertiary referral center. METHODS: This study was performed using a prospective, multi-center registry of septic shock, with the participation of 11 tertiary referral centers in the Korean Shock Society between October 2015 and February 2017. We classified the patients as a transferred group who transferred from other hospitals after meeting the inclusion criteria upon ED arrival and a non-transferred group who presented directly to the ED. Primary outcome was hospital mortality. We conducted multiple logistic regression analysis to assess variables related to in-hospital mortality. RESULTS: A total of 2,098 patients were included, and we assigned 717 patients to the transferred group and 1,381 patients to the non-transferred group. The initial Sequential Organ Failure Assessment score was higher in the transferred group than the non-transferred group (6; interquartile range [IQR], 4–9 vs. 6; IQR, 4–8; P < 0.001). Mechanical ventilator (29% vs. 21%, P < 0.001) and renal replacement therapy (12% vs. 9%, P=0.034) within 24 hours after ED arrival were more frequently applied in the transferred group than the non-transferred group. Overall hospital mortality was 22% and there was no significant difference between transferred and non-transferred groups (23% vs. 22%, P=0.820). Multivariable analysis showed an odds ratio for in-hospital mortality of 1.00 (95% confidence interval, 0.78–1.28; P=0.999) for the transferred group compared with the non-transferred group. CONCLUSION: The transferred group showed higher severity and needed more organ support procedures than the nontransferred group. However, inter-hospital transfer did not affect in-hospital mortality.

Isolated noncompaction of ventricular myocardium, sometimes referred to as spongy myocardium, is a rare congenital cardiomyopathy. Spongy myocardium results from an arrest in normal endomyocardial embryogenesis. The clinical symptoms and electrocardiographic findings of this disorder can be showed variously. The diagnosis is usually made by echocardiography. We report a case of isolated noncompaction of the ventricular myocardium in a 20-year-old male patient initially presented with syncope caused by ventricular tachycardia, who was diagnosed with echocardiography, cardiac MRI and endomyocardial biopsy.
