Spirochetes were isolated from the midgut of Ixodes persulcatus ticks captured at Chungju, Korea and identified as Borrelia afzelii strains by polymerase chain reaction. To determine the pathogenicity of the B. afzelii strains isolated in Korea, the microbiological and pathological features of Lyme disease were observed in C3H/He mice after intraperitoneal inoculation of the fresh isolate of B. afzelii strain. The results are summarized as follows 1) The Borrelia were detected in the tissues of heart, spleen, kidney, urinary bladder and knee joint within 7 days after inoculation of infection by dark field microscopic examination. The isolation rate from heart, urinary bladder and joint was significantly higher than the rate from spleen, kidney, and blood samples. 2) The Borrelia was detected in heart muscle by indirect immunofluorescent antibody test. 3) Antibody to the Borrelia was detected as early as one week after inoculation. 4) The marked tropism of the Borrelia was observed in myocardial, urinary tract and joint tissue. The main pathological features are inflammation in tissues of heart, kidney, joint and urinary bladder. From these results, the Borrelia afzelii strain isolated in Korea were determined as pathogenic strain.

A Cocker spaniel (7-year-old, female) was presented with one week of anorexia, halitosis, oral ulcer, intermittent vomiting, acute weight loss and 3-day history of oliguria. The patient was diagnosed with acute on chronic kidney disease and pancreatitis. Hemodialysis was continued three times a week (total 7 sessions) with improved clinical signs and kidney panel, but presented with another episode of abdominal distention, respiratory distress, and large bowel diarrhea. Echocardiography revealed nearly totally occlusive thrombus in the cranial vena cava, as well as a right atrial mass of approximately $2cm{\times}1cm$. The patient was treated with catheter removal, thrombolysis and anticoagulation therapy with recombinant tissue plasminogen activator. During anticoagulation therapy, size of atrial thrombus was not changed and heart function was not improved after treatment. Since clinical signs were deteriorated, the patient was euthanized by owner's request. Catheter-related giant thrombus in right atrium is a rare complication and treatment guideline for atrial thrombus does not exist. This case is first report of hemodialysis catheter-induced thrombus in Korea.

Using a semi-circled blunt body model, the geometrical effects of injection hole on the turbine blade leading edge film cooling are investigated. The film cooling characteristics of two shaped holes (laterally- and streamwise-diffused holes) and three cylindrical holes with different lateral injection angles, 30°, 45°, 60°, respectively, are compared with those of cylindrical hole with no lateral injection angle experimentally and numerically. Kidney vortices, which decrease the adiabatic film cooling effectiveness, appear on downstream of the cylindrical hole with no lateral injection angle. At downstream of the two shaped holes have better film cooling characteristics than the cylindrical one. Instead of kidney vortices, single vortex appears on downstream of injection holes with lateral injection angle. The adiabatic film cooling effectiveness is symmetrically distributed along the lateral direction downstream of the cylindrical hole with no lateral injection angle. But, at downstream of the cylindrical holes with lateral injection angle, the distribution of adiabatic film cooling effectiveness in the lateral direction shows asymmetric nature and high adiabatic film cooling effectiveness regions are more widely distributed than those of the cylindrical hole with no lateral injection angle. As the blowing ratio increases, also, the effects of hole shapes and injection angles increase.

Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelve meridians(WSBTM) will be representative of measurements of the twelve meridians, to measure the electric potentials of 16 patients with Lumbago due to the kidney deficiency(腎虛腰痛, LKD), to find out the characteristic of meridian system in patients with LKD. Methods : Electric potentials of welt and sea points in the meridians in twenty one patients with the pain in the lion diagnosed as LKD were repeatedly measured by physiograph(PowerLab). Measurements of those electrical potentials were analyzed by factor analysis. Results : The electric potentials of WSBTM at the left side were divided into five factors. On the other hand those at the right side Were divided into t1vee factors. Conclusions : In conclusion, their electrical potentials at the left and right side were four different factors search side. Thus electrical potentials of welt and sea points might be the representative meridian to show their characteristics.

In the literatual studies on the causes and treatments of the melasma, the results were as follows. 1. Melasma is the blackish patch on the face, is belong to the cartegory of the 'Myunjin(面塵)', 'Myunganzung(면간증)', 'Jakban(雀斑)' etc. in Oriental medicine 2. Melasma is deeply associated with Yangming channel in Meridian, with the spleen, stomach, heart and kidney in Viscera. 3. The pathogenic factors of Melasma is divided five parts. One is insufficient of Yangming's energy in Neijing(內經). Two is incoordination between vital energy and blood caused by wind-evil and phlegm-retention syndrome. Three is anxiety impairing the spleen. Four is kidney-asthenia and fire-hyperactivity. Five is heat-evil. 4. In the treatments of Melasma, Sthenia-syndrome was used cooling blood and activating blood circulation, or dispelling wind-evil and promoting meridian, or expelling fire-evil and removing toxic material etc. Asthenia-syndrome was used invigorating the liver and kidney, or nourishing yin and keeping fire downwards etc. 5. Melasma is concerned with sun-light, is mostly seen in female. 6. In the prescription of Melasma, it was used Jujesamultang(酒製四物湯加減), Okyong -san(玉容散), Chunghwasungitang(沖和順氣湯), Okyongseosisan(玉容西施散), Yukmiji-hwanghwan(六味地黃丸) etc.

The disease-causing koi herpes virus (KHV), also known as cyprinid herpesvirus-3 (CyHV3), causes mass mortality of koi and carp. Koi (Cyprinus carpio) is a host for KHV, one of 12 virus species in the Alloherpesviridae family. We examined the effects of KHV disease koi (KK), and on koi×red common carp (KR) and red common carp×koi (RK) cross, using a virus challenge test. The infected fish had clinical signs that included gill necrosis and skin lesions. The RK and KR were highly more resistant (cumulative mortality: RK; 6% and KR; 8%) to KHV infection than KK fish (cumulative mortality: 28%). KHV DNA was confirmed in the tissues of all dead fish in groups by use of polymerase chain reaction (PCR), and the presence of the KHV protein in kidney was confirmed by immunohistochemistry. Histological analysis showed severe gill lesions and fusion of the lamellae in KK fish, but less severe damage in RK fish. In immunohistochemistry analysis, the KHV protein localized in the cytoplasm of infected kidney cells of KK, but the cross groups had lower levels of KHV antigen. Our data indicate that the cross groups had increased resistance to KHV disease.

Purpose: To determine the prevalence, clinical manifestations, and outcomes of renal involvements in pediatric Alagille syndrome (ALGS). Methods: A total of 21 patients diagnosed with ALGS at age under 18 years who visited Samsung Medical Center from March 1999 to March 2022 were enrolled. ALGS was diagnosed either by clinical manifestations, targeted JAG1 sequencing, and/or liver biopsy. Medical records including sex, age, renal manifestations, urinalysis, serum creatinine, JAG1 sequencing, and ultrasonography were retrospectively reviewed. Results: The male to female ratio was 9:12. The mean age of patients at confirmative diagnosis of ALGS was 18.4 months. Sanger sequencing was performed for 17 patients. Sixteen of 21 patients (76.1%) showed JAG1 mutations. Renal involvement was found in 10 patients (47.6%). The most common type of anomaly was renal dysplasia (40%). One patient having renal dysplasia was pathologically confirmed with glomerular lipid deposition. Two patients (20%) manifested nephrocalcinosis/nephrolithiasis. Among eight renal-involved patients who survived, four (50%) progressed to chronic kidney disease stage 3. Two of these chronic kidney disease patients were diagnosed with hepatorenal syndrome. The other four patients had renal functions preserved, including two without any interventions and two who underwent urological interventions. Conclusions: The current study revealed a high prevalence of renal involvement in Korean pediatric ALGS with diverse phenotypes.
