Loop-mediated isothermal amplification (LAMP), a PCR-based diagnostic method, is based on autocycling strand displacement DNA synthesis in the presence of exonuclease-negative Bst DNA polymerase under isothermal conditions. With the help of four specific primers that recognize six different sequences of a target DNA, LAMP has high specificity in pathogenic identification in a short time. Hence, in the present study, LAMP is used as a diagnostic tool in the identification of the most dreadful aquatic pathogenic species, Vibrio alginolyticus, and to develop species-specific LAMP primers and optimization of LAMP reaction conditions such as annealing temperature, elongation time, and other PCR chemical concentrations, including MgSO4, dNTPs, Betaine, and Bst polymerase. The optimized LAMP primers were also checked for specificity with other Vibrio species, which showed that the designed primers were very specific to V. alginolyticus After the first introduction of a species name like this one, the first part (“Vibrio” in this case) should be abbreviated to only the first letter.only. These are usually the most harmful pathogens of the Vibrio species that appear in shrimp and crabs. The results also revealed that the LAMP assay could be 10-fold more sensitive than conventional PCR in detecting V. alginolyticus. This could be the first report on using a rapid and highly sensitive technique, the LAMP assay, in the effective diagnosis of the pathogenic bacteria V. alginolyticus, which could help in the early detection of diseases, particularly in aquaculture.
Recently, in each local self-governments Japan, the importation of universal design policy is actively being expanded as a plan to maximize living satisfaction of.citizens within the region. This research investigates the background on how the local self-governments ended up importing the universal design administrative policy, investigates the policies which each self governing bodies have been promoting and presents necessary stipulations following those policies. When we sum up the necessity of promoting universal design by local self-governments, although the we carry various problems in the promoting process in the settlement of provincial era and promoting substantiality of it, we can point out the low birth rate phenomenon, progression of aged people's society, diversification of values as a result of social and economic maturity, etc. as social and economic background. For people's values, as they escape from the economic they attach great importance to economic supremacy, they respect culture, environment, etc. with higher level than economic aspect and the improvement of life's quality is becoming important. Meanwhile, the universal design which is known to many users as a usable design concept as reach to a point where it is getting attention as a basic concept of 21st century design. Today, each of local self-governments in Japan are making various efforts for unperturbed importation and application of universal design to local communities through homepage, universal design guideline or report, various workshops, etc. Especially, there are universal design policies of public areas, facilities, manufacture of other products and information for the contents of the policy. The enforcement of universal design policy puts importance in 1) the process of planning, alteration, policy scheme and decision making 2) the process of policy's enforcement 3) the probation process of all processes and I could find out that equal participation of roles by local citizens, citizen's organizations, companies with the administration hasn't been adopted for each of these processes.

Pulmonary arterial hypertension (PAH) is a common complication of Congenital heart defects (CHD) with left-to-right shunts, and PAH with increased pulmonary vascular resistance (PVR) is associated with considerable morbidity and mortality. General anesthesia (GA) can be life-threatening in patients with PAH, because the positive pressure ventilation during GA increases pulmonary arterial pressure and decreases pulmonary blood flow. This may also lead to hypoxia. Therefore, spontaneous ventilation may be safer than positive pressure ventilation in patients with PAH. A five-year-old male child, weighing 11 kg, with medical history showing a total correction of Tetralogy of Fallot (TOF) in 2009 and ongoing treatment with hypertension (HTN) medicine since 2007, visited the Dankook University Dental Hospital. He had multiple dental caries, and the treatment was completed under sevoflurane insufflation sedation via nasal cannula. The patient remained sedated throughout the operation while maintaining normal vital signs and spontaneous respiration. In conclusion, sevoflurane insufflation sedation may be a safer alternative to GA for the dental treatment of patients with PAH.
A 7-year-old castrated, domestic shorthair cat was presented with a 2-year history of chronic nasal discharge and sneezing. Upon presentation, bilateral mucopurulent nasal discharge and stertorous respiration were marked. Physical examination revealed a tachypnea. Oral examination was unremarkable and chest radiology was normal. Findings of nasal cytology and skull radiology were not specific and further imaging technique, endoscopic examination and histopathology was performed for a definite diagnosis. Fluid, and/or soft tissue opacity was found in bilateral nasal cavity, nasopharyngeal regions and right side tympanic bulla through the CT scan. No evidence of neoplasia was revealed. A rigid rhinoscopy, flexible bronchoscopy and otoscopy was used for the visualization of the lesions and tissue biopsy biopsy was performed for histopathology. On histopathological examination, the nasal mass consisted mainly of large numbers of plasma cells and lymphocytes. And the final diagnosis was lymphoplasmacytic rhinitis based on histopathologic examination. Long term management with oral cyclosporine (5 mg/kg, BID) was safe and successful in this cat. This is the first case report described clinical and diagnostic characteristic features of feline lymphoplasmacytic rhinitis and its clinical outcome using oral cyclosporine in Korea.
A 14-year-old neutered female Chihuahua was presented because of seizure episodes and circling to the left side. Based on neurological examination, the lesion was localized on left forebrain. The mass in the left nasal cavity and breaching of the nasal septum were seen magnetic resonance images. And there was a presence of contrast enhanced mass involving the rostral left brain. Based on diagnostic image analysis, this lesion strongly suggested secondary brain tumor infiltrated by nasal cavity. The patient's symptoms were well controlled by a combination therapy of prednisolone and lomustine (CCNU), and survived for two months after diagnosis. This case was definitively diagnosed as a nasal neuroendocrine carcinoma based on histopathological findings. This report describes the clinical findings, imaging characteristics, and pathologic features of secondary brain tumor which caused by infiltration of nasal neuroendocrine carcinoma in a dog.
Objective: This study aimed to report the level of extremely low frequency-magnetic field (ELF-MF) emitted by portable hand-held fans (HHF) and to discuss the methodologies for determining the health risk of ELF-MF for HHF products. Method: ELF-MF was monitored at eight locations by distances in the vicinity of HHFs. A total of 13 HHF brands on the market were randomly selected. A portable ELF-MF monitor MDEX II was used to measure the ELF-MF level in the range of 40-800 Hz with a resolution of $0.01{\mu}T$. This study also examined the frequency results of a total of 45 HHF products investigated by the Korean Ministry of Science and ICT (KMSICT). Results: ELF-MF higher than $0.3{\mu}T$ was found to be emitted at a distance of less than 20 cm from 12 HHF. ELF-MF emitted from four products was found to exceed the reference level ($83.3{\mu}T$ based on 60 Hz) recommended by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). KMSIT reported that the principle frequency emitted from the HHFs ranged from 54 Hz to 284 kHz, without the level of LEF-MF. Unscientifically, the KMSICT used the reference level by ICNIRP as the chronic level and concluded that all HHFs are safe with a basis of 1.2-36.0% less than the reference level. Conclusion: The HHF emitted much higher levels of ELF-MF than $0.3-0.4{\mu}T$, which is regarded as the reference level for childhood leukemia. The risk of HHF should be examined in terms of whether they can be used by the general public, including children and pregnant woman.

Hepatic duct confluence injury, which is developed by blunt abdominal trauma, is rare. Conventionally, bile duct injury was treated by surgical intervention. In recent decades, however, there had been an increase in radiologic or endoscopic intervention to treat bile duct injury. In a hemodynamically stable patient, endoscopic intervention is considered as the first-line treatment for bile duct injury. A 40 year-old man was transferred to the emergency department of ${\bigcirc}{\bigcirc}$ trauma center after multiple blunt injuries. Contrast-enhanced abdominal computed tomography performed in another hospital showed a liver laceration with active arterial bleeding, fracture of the sacrum and left inferior pubic ramus, and intraperitoneal bladder rupture. The patient presented with hemorrhagic shock because of intra-peritoneal hemorrhage. After resuscitation, angiographic intervention was performed. After angiographic embolization of the liver laceration, emergency laparotomy was performed to repair the bladder injury. However, there was no evidence of bile duct injury on initial laparotomy. On post-trauma day (PTD) 4, the color of intra-abdominal drainage of the patient changed to a greenish hue; bile leakage was revealed on magnetic resonance cholangiopancreatography and endoscopic retrograde cholangiopancreatography (ERCP). Bile leakage was detected near the hepatic duct confluence; therefore, a biliary stent was placed into the left hepatic duct. On PTD 37, contrast leakage was still detected but both hepatic ducts were delineated on the second ERCP. Stents were placed into the right and left hepatic ducts. On PTD 71, a third ERCP revealed no contrast leakage; therefore, all stents were removed after 2 weeks (PTD 85). ERCP and biliary stenting could be effective treatment options for hemodynamically stable patients after blunt trauma.
Further elucidation of the mechanism of halothane's negative inotropic action has resulted from a study of the effect of various substrates on halothane-depressed rat atria. Approximately 6 mg% halothane was required to maintain a 50% depression of the contractility of rat atria suspended in a modified Krebs-Ringer bicarbonate glucose medium, pH 7.4, $30^{\circ}C$ for 2hr. Both lactate and acetate were found to restore partially the contractility of halothane-depressed atria. The maximally effective concentration of lactate was 5 mM; for acetate it was 2.5mM. Neither 5 nor 20 mM of additional glucose was effective in restoring the force of contraction of halothane-depressed atria. The results are consistent with the hypothesis that halothane exerts at least a part of its negative inotropic effect on rat atria by inhibiting either the uptake or utilization of glucose by the myocardium. The site of blockade must be prior to the conversion of pyruvate to acetyl CoA. In our previous report dealing with the mechanism of cardiac depressant action of inhalation anesthetic halothane, it has been demonstrated that: 1) approximately 6 mg/100 ml halothane is required to maintain 50% depression of the force of contraction of isolated rat atria in Krebs-Ringer bicarbonate glucose medium; 2) pyruvate partially restores the contractility of halothane-depressed atria, but has no effect on normal atria; the partial recovery of depressed atria by the addition of sodium pyruvate is due to the effect of the pyruvate ion itself, not to the sodium ion; 4) addition of pyruvate, to atria depressed with hypertonic medium, produced only further depression. From these findings we concluded that the cardiac depressant action of halothane on rat atria is a manifestation of inhibition of glucose uptake or utilization. The present studies were undertaken to observe the effect of other substrates on halothane-depressed atria in order to substantiate our conclusion. As with the case of pyruvate, lactate and acetate also partially restored the force of contraction of halothane-depressed atria. These data are consistent with the hypothesis that halothane inhibits glucose uptake or utilization in the glycolytic cycle of the myocardium.

Background and Objective : Soft palate plays a great role in function of speech and swallowing. Ablation of tonsil cancer results in multi-demensional defect including soft palate in most cases and restoration of the postoperative oral cavity function is a continuing surgical challenge. Although a variety of techniques are available, radial forearm free flap has been known as an effective method for these defect, which offers a thin, pliable, and relatively hairless skin, and a long vascular pedicle. The aim of the present study is to report the speech and swallowing function test results of our 5 consecutive radial forearm free flaps used for tonsil cancers. Materials and Methods : We reviewed the medical records of 5 patients who were offered intraoral reconstruction with a radial forearm free flap after ablative surgery for tonsil cancers, from Dec. 1997 to Oct. 1998, and analyzed the surgical methods, complications, and speech and swallowing function test results. We have examined with modified barium swallow to evaluate postoperative wallowing function and articulation and resonance test for speech. Results : The tumor sizes by TNM stage(AJCC, 1997) were T1(1), T2(2), and T4(3). The paddles of flaps were tailored in multilobed designs from oval shape to pentalobed design and in variable size from 24$cm^2$ to 108$cm^2$(average size = 78.4$cm^2$), according to the defect after ablation. This procedures resulted in satisfactory flap success and functional results all but 1 case of flap contracture in 2 postoperative week, achieved early oral diet until 16-57 postoperative day(average, 28 days) and social speech. The oropharyngeal defect including soft palate reconstruction with radial forearm free flap might be an excellent method for the maximal functional results, after ablative surgery of tonsil cancer that results in multidimensional defect.
Bypass surgery is performed for insuring continuity of a blood supply that is restricted due to obstruction of the native blood supply. Two types of surgery are commonly carried out: one is anatomic bypass and the other is extraanatomic bypass. Especially, extraanatomic bypass surgery is performed in patients who are a high risk for performing anatomical bypass surgery. The risk factors for anatomical bypass surgery are old age, infection, previous surgery and trauma. A 96-year-old patient underwent extraanatomic bypass surgery from the right femoral artery to the left femoral artery due to total occlusion of the left iliac artery, and 7 years after that operation, a pseudoaneurysm abruptly and spontaneously appeared from the bypass suture site without any predisposing factor. The lesion was revealed to be an organizing thrombus.
