Oxytetracycline has been widely used in the cattle industry to control pneumonia, shipping fever, foot rot, bacterial enteritis, and uterine infections. Extensive use of antibiotics in veterinary clinics has resulted in residues in tissue and bacterial resistance to antibiotics. To prevent unwanted drug residues from entering the human food chain, extensive control measures have been established by both government authorities and industries. The demands for reliable, simple, sensitive, rapid and low-cost methods for residue analysis of foods are increasing. In this study, we established a rapid test for tissue residues of oxytetracycline in cattle. The recommended therapeutic dose of oxytetracycline (withdrawal time, 14 days) was administered to 10 cattle. Blood samples were collected from each cow before drug administration and during the withdrawal period. The concentration of oxytetracycline in plasma, determined by a semi-quantitative ELISA, was compared to that of the internal standard, 10 ppb. The absorbance ratio of internal standard to sample (B/Bs) was employed as an index to determine whether the residues in cattle tissues were negative or positive. That is, a B/Bs ratio less than 1 was considered as residue positive and that greater than 1 as negative. Based on this criterion, all plasma samples from cattle were negative to oxytetracycline at pre-treatment. Oxytetracycline could be detected in the plasma treated cattle until day 14 post-treatment. The present study showed that the semi-quantitative ELISA could be easily adapted in predicting tissue residues for oxytetracycline in live cattle.
Objectives and Backgrounds : After parotidectomy, some of patients complain gustatory sweating, facial flushing and discomfort in the same area. A series of these symptoms are supposed to be caused by the aberrant regeneration of the secretory parasympathetic fibers to sweat glands and blood vessels of the skin following parotidectomy. In this study, we want to compare the efficacy of thermography to the Minor's starch-iodine test for determining the presence of Frey's syndrome. Materials and Methods : 48 patients who underwent total or superficial parotidectomy from March 2002 to December 2004 were selected for this study. A subjective clinical questionnaire and the objective Minor's starchiodine test were performed to evaluate the incidence of this syndrome. Total 21 patients were confirmed as positive Frey's syndrome and infrared thermography was performed for them. Result : Frey's syndrome occurred in 21 patients(43.8%). The average temperature of parotidectomy site and normal opposite area were $27.65^{\circ}C\;and\;26.41^{\circ}C$ respectively. Thermography showed temperature difference in 20 patient(95.2%) and the difference of temperature was statistically significant above $1.0^{\circ}C$(p<0.001). The severity of symptoms were related with the difference of temperature(p<0.05). Conclusion : Thermography is useful, non-invasive, simple and quantifying method to diagnose Frey's syndrome. Additionally, this geographic diagnosis is available to show the accurate area for botulinum toxin injection.

Purpose: The aim of this study was to evaluate inflammation parameters and assess the utility of the neutrophil-lymphocyte ratio (NLR) as a simple and readily available predictor for clinical disease activity in patients with nenign prostate hyperplasia BPH. We also aimed to investigate the relationship between inflammatory parameters with ${\alpha}$-blocker therapy response, and evaluate the potential association between NLR and the progression of benign prostatic hyperplasia (BPH). Materials and Methods: We examined 320 consecutive patients (July 2013-December 2013) admitted to our outpatient clinic with symptoms of the lower urinary tract at Bozok University. The mean age was 60 (range, 51-75) years. Complete blood count (CBC), prostate-specific antigen (PSA), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) were assessed. Correlations between PSA, CRP, ESR, prostate volume, International Prostate Symptom Score (IPPS), maximum urinary flow rate (Qmax), and NLR were assessed statistically. Patients were divided into two groups: high and low risk of progression. Results: NLR was positively correlated with IPSS (p=0.001, r=0.265), PSA (p=0.001, r=0.194), and negatively correlated with Qmax (p<0.001, r=-0.236). High-risk patients a had a higher NLR compared with low-risk patients, based on IPSS (p<0.001), PSA (p=0.013), and Qmax (p<0.001); however, there were no significant differences between the groups in terms of age (p>0.05), and prostate volume (p>0.05). Conclusions: NLR can predict BPH progression. We propose that increased inflammation is negatively associated with clinical status in BPH patients and suggest that NLR can give information along with LUTS severity which may be used as a readikly accessible marker for patient follow-up.
Objectives : The prescription of Semyung-Gangji-tang, designed for the treatment of hyperlipidemia and atherosclerosis, consists of herbs good for treating blood stasis and phlegm stagnancy. It invigorates the liver, kidneys and spleen. Its medical nature is not too cold or too hot and increases human vital energy. The purpose of this study is to examine the curative effects of Semyung-Gangji-tang on atherosclerosis in hyperlipidemic rabbits. Methods : Twenty-four male NZW rabbits, around 2kg of body weight, were divided into 4 groups. Group I served as the normal group. Group II served as the atherogenic model group, fed a 1 % cholesterol diet for 8 weeks and sacrificed. Group III served as the atherogenic control group, fed with a 1 % cholesterol diet for 8 weeks and with a normal diet for the next 4 weeks. Group IV served as the treatment group treated the same as the control group and medicated with Semyung-Gangji-tang for the last 4 weeks. Three animals of group I and six animals of group n were sacrificed at 8 weeks. Five animals of group I , five animals of group III and IV were sacrificed at 12 weeks. Pathological examinations and image analysis were performed on the collected tissue samples. Results : The percentage of lipid deposition area of thoracic aortas of group IV($41.74{\pm}8.93%$) at 12 weeks was decreased compared with the group III ($71.30{\pm}12.74%$) at 12 weeks, but a statistical difference was not observed. The percentage of group IV at 12 weeks was significantly decreased (P<0.05) compared with the group n ($76.41{\pm}7.43%$) at 8 weeks. Histopathologically, advanced atheromas with calcification of aortic arches were observed in all animals of the control group at 12 weeks, but were observed in 2 animals of the treatment group at 12 weeks. Histopathologically, atheromas with calcification of thoracic aortas were observed with major atherogenic lesions in control group at 12 weeks, but simple fibro-fatty streaks were observed major atherogenic lesions in treatment group at 12 weeks. Conclusions : These results indicate that Semyung-Gangji-tang has antiatherogenic effects on experimentally induced atherosclerosis in rabbits.
Using the hematofluiorometer normal values of the erythrocyte zinc protoporphyrin(ZPP) and ZPP/Heme ratio were measured in 312 males and 163 females aged from 6 month to 73 years old and compared with those of anemic persons. The mean$\pm$SD values of ZPP of normal Koreans were 28.5$\pm$6.4($\mu\textrm{g}$/dl) in males and 3.18$\pm$7.7 in females. the mean$\pm$SD of ZPP/Heme ratio were 49.5$\pm$12.3($\mu$mol/mol heme) in males and 62.0$\pm$15.8 in females. The difference in the mean ZPP and ZPP/Heme ratio values between male and female subjects were statistically signficant(p<0.0001) In male subjects the mean ZPP and ZPP/Heme ratio of the age groups less than 15 years old were higher than adult groups and the difference between age groups was significant(p<0.005 and p<0.0001 respecti-vely) The normal upper limit of the mean$\pm$2SD in normal male and female subjects were 41.3 and 47.2 for ZPP and 74.1 and 93.6 for ZPP/Heme ratio respectively. The mean values of ZPP and ZPP/Heme ratio measured in the anemic persons were higher than those of normal subjects and did not show any significant difference by the sex and age groups except in 6-14 years male groups. The test specificity(positivity) analyzed in the anemic persons by the cut-off values calculated from the normal data were 50.6% for ZPP and 73.0% for ZPP/Heme ratio. The correlation analysis between blood hemoglobin and erythrocyte ZPP or ZPP/Heme ratio in the total 801 normal and anemic subjects showed that there are very high logarithmic correlation between the hemoglobin levels and ZPP/Heme ratio (r=-0.8339) and high correla-tion between the hemoglobin levels and ZPP concentrations(r=-0.6372) These results suggested that the measurement of the erythrocyte ZPP and ZPP/Heme ratio with the hematofluorometer can be a usuful screening method for iron deficiency anermin because they provide a reliable immediate results with a small amount of sample and are relatively simple and inexpensive.
Objective : Carotid endarterectomy (CEA) is an effective surgical procedure for treating symptomatic or asymptomatic patients with carotid stenosis. Many neurosurgeons use a shunt to reduce perioperative ischemic complications. However, the use of shunting is still controversial, and the shunt procedure can cause several complications. In our institution, we used two types of modified arteriotomy suture techniques instead of using a shunt. Methods : In technique 1, to prevent ischemic complications, we sutured a third of the arteriotomy site from both ends after removing the plaque. Afterward, the unsutured middle third was isolated from the arterial lumen by placing a curved Satinsky clamp. And then, we opened all the clamped carotid arteries before finishing the suture. In technique 2, we sutured the arteriotomy site at the common carotid artery (CCA). We then placed a curved Satinsky clamp crossing from the sutured site to the carotid bifurcation, isolating the unsutured site at the internal carotid artery (ICA). After placing the Satinsky clamp, the CCA and external carotid artery (ECA) were opened to allow blood flow from CCA to ECA. By opening the ECA, ECA collateral flow via ECA-ICA anastomoses could help to reduce cerebral ischemia. Results : The modified suture methods can reduce the cerebral ischemia directly (technique 1) or via using collaterals (technique 2). The modified arteriotomy suture techniques are simple, safe, and applicable to almost all cases of CEA. Conclusion : Two modified arteriotomy suture techniques could reduce perioperative ischemic complications by reducing the cerebral ischemic time.
Purpose: Microvascular free tissue transfer has become a reliable technique for the reconstruction of complex wounds. Occasionally, unexpected intraoperative thrombosis and/or spasm of recipient artery might be annoying problems even for the technically competent microvascular surgeons. If such problems are not treated properly, they will inevitably cause to flap failure. Methods: From January 2006 to February 2007, soft tissue reconstructions by free tissue transfers were performed on 21 patients having complex defects in the lower extremity. Although segmental revision and various pharmacologic agents were repeatedly applied, arterial occlusions were not managed in 6 cases. For removal of thrombi and release of spasm, Fogarty No. 2 or No. 3 catheters were inserted into the lumen to the proximal recipient artery. Its balloon was then inflated after passing through a resistant area. Next, the catheter was gently withdrawn backward. Results: After the Fogarty catheter was inserted two or three times, the pulsatile arterial flow was restored. When the catheter was inserted into the lumen, a feeling of resistance existed in a 5-10cm more proximal portion that could not be easily accessed from the vascular end. After the reestablishment of blood flow, successful anastomoses were achieved and immediate rethrombosis or spasm did not occur. No long-term sequelae associated with balloon trauma to the arterial wall were observed. Conclusion: The use of the Fogarty catheter can be an effective method in treating pedicle thrombosis and spasm. This is a very simple and rapid technique that offers microvascular surgeons another option to increase the success rate of microvascular anastomosis in free tissue transfers.
Purpose: The coverage of distal soft tissue defects and bony exposure of the lower extremity has long been recognized to be difficult clinical problem. Covering with a local skin flap is usually impractical because of the extensive and deep crush, hence free flap has been used commonly for the coverage of the wound. Although it can provide good results, it has many disadvantages. Designing an adipofascial flap raised on perforating vessels of the posterior tibia artery is a reliable and simple method to perform, and it can solve these problems. Methods: From May 2005 to May 2006, 8 patients underwent reconstruction of lower leg defects utilizing various type of the posterior tibial artery perforator adipofascial flaps. The flap provided a durable and thin coverage for the defect, as well as a well vascularized bed for skin grafting. Results: The flap size ranged $15-80cm^2$, and skin graft was done for the recipient site. The flap were successfully used for the lower extremity reconstruction in most cases. Minor complications occurred in 4 cases. There was no functional disability of the donor site with esthetically pleasing results. Furthermore, these flaps were both easy to raise and insured sufficient arterial blood supply. Conclusion: We believe there are many advantages to this posterior tibial artery perforator adipofascial flap and that it can be highly competitive to the free flaps in the lower extremity reconstruction.
Purpose: Non-alcoholic fatty liver disease (NAFLD) ranges in severity from simple steatosis to steatohepatitis. Early detection of NAFLD is important for preventing the disease from progressing to become an irreversible end-stage liver disease. We developed a nomogram that allows for non-invasive screening for NAFLD in obese children. Methods: Anthropometric and laboratory data of 180 patients from our pediatric obesity clinic were collected. Diagnoses of NAFLD were based on abdominal ultrasonographic findings. The nomogram was constructed using predictors from a multivariate analysis of NAFLD risk factors. Results: The subjects were divided into non-NAFLD (n=67) and NAFLD groups (n=113). Factors, including sex, body mass index, abdominal circumference, blood pressure, insulin resistance, and levels of aspartate aminotransferase, alanine aminotransferase (ALT), γ-glutamyl transpeptidase (γGT), uric acid, triglycerides, and insulin, were significantly different between the two groups (all p<0.05) as determined using homeostatis model assessment of insulin resistance (HOMA-IR). In our multivariate logistic regression analysis, elevated serum ALT, γGT, and triglyceride levels were significantly related to NAFLD development. The nomogram was established using γGT, uric acid, triglycerides, HOMA-IR, and ALT as predictors of NAFLD probability. Conclusion: The newly developed nomogram may help predict NAFLD risk in obese children. The nomogram may also allow for early NAFLD diagnosis without the need for invasive liver biopsy or expensive liver imaging, and may also allow clinicians to intervene early to prevent the progression of NAFLD to become a more advanced liver disease.

Among clincal isolates, most strains of Serratia marcescens were belonged to nonpigmented form, and several attempts were undertaken for the rapid and simple identification of these strains. Prodigiosin production of non-pigmented strains was uniformly negative in many kinds of solid media as well as in nutrient agar added with various amino acids and thiamine. On blood agar, colonies of S. marcescens turned gradually to grey or dark color by the lapse of incubation period and this characteristic seems to be able to utilize as an indicator for a primary isolation, and also generally paralleled with the results of dehydration of Tween 80 and lipase activity in soy bean oil medium although these reactions were by no means specific to S. marcescens. In order to rule out these non-specific reactions, other tests such as oxidase and sucrose fermentation are required for the final confirmation of this species.
