Investigation of meridian line and acupoints as anatomical entities should be very important, as acupuncture and meridian massage for medical purpose in the hospital or for skin care in beauty shop are each based on the traditional meridian theory. We isolated tubular structures under the skin of rabbits where the traditional meridian lines are located. The characteristics of these tubular structures isolated from the abdominal wall matches those of Bonghan tubes and Bonghan tubules found by Bong Han Kim. The Bonghan theory established by Bong Han Kim suggests that meridian lines consist of Bonghan tubes and Bonghan tubules. We could observe the presence of large cells inside the Bonghan tubule and the presence of small granules referred to as Sanal in Bonghan theory inside the striae consisting of the Bonghan tubules. Present research suggests that there exist a third unique tubular structure where Sanals flow other than Bonghan tube and Bonghan tubules.

Investigation of meridian line and acupoints should be very important, as acupuncture and meridian massage for medical purpose in the hospital or for skin care in beauty shop are all based on traditional meridian theory. Radioactive technetium-99m pertechnetate (^99mTc) injected to a specific acupoint flowed upward along the meridian line as was suggested by traditional meridian theory. Tracing of injected ^99mTc to an acupoint revealed that the meridian is a unique ductal system through which the materials flow.

고일용,서진석,김황민,손준형,예병일,이택진,김동수,Ko, Il Yong,Suh, Jin Suk,Kim, Hwang Min,Sohn, Joon Hyung,Yeh, Byung-Il,Lee, Taek Jin,Kim, Dong Soo 대한소아감염학회 2007 Pediatric Infection and Vaccine Vol.14 No.2

목 적 : EBV 감염은 발생 연령에 따라 혈청학적으로 진단되지 않을 수 있으며, 이 때 실시간 중합효소연쇄반응이 대신할 수 있는 진단 방법이다. 본 연구는 임상적으로 EBV 감염이 의심되는 환자에서 각각 혈청학적 검사 양성인 경우와 실시간 중합효소연쇄반응 양성인 그룹간의 임상양상을 비교하고자 하였다. 방 법 : 2004년 1월부터 2006년 12월까지 EBV 감염이 의심되는 45명의 환자를 대상으로 EBV 실시간 중합효소연쇄반응 검사를 시행하여 EBV 바이러스혈증의 존재 여부를 확인하였다. $102.5copies/{\mu}g$ DNA를 EBV 연관질병의 결정 수준으로 삼았다. 결 과 : EBV 감염이 혈청학적으로 진단된 환자는 4명이었으며 실시간 중합효소연쇄반응으로 EBV 바이러스혈증이 확인된 환자는 15명이었다. EBV 바이러스혈증이 있는 환자군의 나이는 4세 미만이 73%(11/15)였고 남녀비는 1:1.3 이었다. 입원 시의 임상증상은 발열이 73%(11/15), 인두 발적이 67%(10/15)에서 보였으며 동반된 질환으로는 급성 위장관염과 폐렴이 각각 20%(3/15)였다. 비정형 림프구가 15% 이상인 경우는 27%(4/15)에서 보였고 AST, ALT의 증가가 각각 87%(13/15), 80%(12/15)였다. CRP가 2 mg/dL 이하인 경우는 87%(13/15)였다. EBV 바이러스혈증 환자중 1세 미만은 5명으로 이들 중 80%(4/5)에서 발열이 동반되었고 비정형 림프구는 보이지 않았으며 모두 AST, ALT가 증가하였다. 혈청학적으로 진단된 환자군의 나이는 1-6세였고 75%(3/4)에서 간비대와 비장비대가 보였으며 50%(2/4)에서 발열, 인두발적, 경부 림프절 종대가 보였다. 동반된 질환은 없었으며 백혈구가 모두 $20,000/mm^3$ 이상이었고 50%(2/4)에서 비정형 림프구가 증가했으며 AST, ALT가 50 IU/L 이상으로 상승하였다. CRP는 모두 1 mg/dL 이하였다. 결 론 : 혈청학적 검사에서 진단되지 않았더라고 실시간 중합효소연쇄반응에서 EBV 바이러스혈증을 보인 환자는 EBV 감염의 일반적인 임상증상을 보였다. 따라서 EBV 감염이 의심되는 환자, 특히 1세 미만의 환자는 혈청학적 검사가 음성이어도 실시간 중합효소연쇄반응을 통해 바이러스 혈증을 확인하는 것이 EBV 감염의 진단률을 높이는데 의미가 있을 것으로 사료된다. Purpose : We investigated clinical characteristics of real-time PCR proven EBV viremia patients who were not serologically diagnosed but clinically suspected, and compared it to serologically proven EBV infected patients. Methods : The study population consisted of 45 patients, who were suspected acute EBV infection at Wonju Christian Hospital Department of Pediatrics, Yonsei University Wonju College of Medicine from Jan. 2004 to Dec. 2006. real-time PCR of cell free serum was performed to prove EBV viremia. Then we chose $102.5copies/{\mu}g$ DNA as a suitable cutoff level for EBV associated diseases. Results : There are 4 patients diagnosed as EBV infection by serologically and 15 patients diagnosed as EBV viremia by real-time PCR quantitative measurement. The most common presenting symptoms and signs of EBV viremia was fever in 11 cases (73%). Atypical lymphocytosis was found in 4 cases (27%). Increased AST, ALT levels were observed in 13 cases (87%), 12 cases (80%), respectively. We could diagnose 5 cases of EBV viremia younger than one year of age. They revealed clinical symptoms which could be found in EBV infection. The serologically diagnosed patients had hepatomegaly and splenomegaly in 3 cases (75%). All serologically confirmed patients have leukocytosis above $20,000/mm^3$, among them 2 cases (50%) had higher percentage (>15%) of atypical lymphocytes. The AST/ALT level above 50 IU/L were demonstrated in all cases. Conclusion : Serologically unproven real-time PCR EBV viremia patients revealed similar clinical findings with that of serologically proven EBV infected patients. So, it is meaningful to perform EBV real-time PCR for the diagnosis of EBV infection especially for the cases younger than 1 year of age.

김성국 ( Seong Guk Kim ),손준형 ( Joon Hyung Sohn ),장영술 ( Young Sul Jang ),김상윤 ( Sang Yoon Kim ) 한국동물위생학회 2012 韓國家畜衛生學會誌 Vol.35 No.4

Canine brucellosis is the zoonosis in worldwide and Brucella (B.) canis is a facultative intracellular pathogen that has a very limited host. MLVA-16 (Multilocus VNTR analysis) is a efficient method for genotyping of Brucella species. Various methods have been established for genotyping of Brucella species, but most of analytical method is lack reproducibility and limited capability to differentiate them. B. canis isolates (n=73) from 7 farms in Gyeongbuk province in 2003∼2010 were analyzed using 16 VNTR loci. Automatic electro-phoresis system was utilized for more high throughput and rapid simple discrimination. Thirty two genotypes were identified from 73 B. canis isolates. MLVA could contribute to molecular typing for epidemiological evaluation of canine brucellosis.

Cordyceps scarabaeicola KEFC-C252의 균사체 배양에 의한 수용성 색소의 생산과 색소의 항돌연변이 효과

이현우,손준형,최종환,예병일,신운섭,김중배,김현원 한국산업미생물학회 2000 한국미생물·생명공학회지 Vol.28 No.2

Cordyceps scarabaeicola KEFC-C252 균사체의 배양으로 생산되는 천연색소의 생산조건 및 색소의 정제방법을 조사하였으며, 분리된 색소의 항돌연변이 효과를 조사하였다. 색소의 생산에 적합한 배지는 1.5% sucrose, 2.5% yeast extract, 초기 pH5.5였다. C. scarabaeicola KEFC-C252를 26℃에서 108시간 배양한 후에 색소생산이 최대에 달하였으며, 최적조건에서 C. scarabaeicola KEFC-C252는 1.2 g/liter의 색소를 생산하였다. 색소는 ethylacetate 추출, 산침전 및 결정화과정을 거치면서 정제하여 황색의 육각기둥 모양의 결정을 얻었다. 분리된 색소는 용액의 pH변화에 따라 색상이 변하는 특성을 나타내었는데 알칼리성 용액에서 청색, 산성 용액에서 붉은색을 나타내었다. 분리된 색소는 4-NQO로 유도된 돌연변이를 억제하는 항돌연변이원성 물질이었다. 또 분리된 색소는 Salmonella typhimurium TA98과 TA100에서 자발적 돌연변이를 감소시켰다. Cultural conditions for the production of water-soluble pigment from mycelial culture of Cordyceps scarabaeicola KEFC-C252 and antimutagenic activity of the pigment were investigated. To obtain the maximum productivity of the pigment from mycelial culture of C. scarabaeicola KEFC-C252, the optimized medium was made with 1.5% sucrose, 2.5% yeast extract and initial pH 5.5. C. scarabaeicola KEFC-C252 was cultivated to reach the maximum concentration of the pigment at 26℃ for 108 hrs. C. scarabaeicola KEFC-C252 produced about 1.2 g/liter pigment under the optimized condition. The pigment was isolated from the culture filtrate by ethylacetate extraction, acidic precipitation and crystallization. The isolated pigment was scarlet hexagonal column crystal, and the color of the pigment was changed according to pH of the solution. The pigment showed violet in the alkaline water but showed red color in the acidic water. The pigment showed inhibitory activity against mutagenic activity induced by 4-nitroquinoline N-oxide. Furthermore, the pigment showed inhibitory activity against spontaneous mutation on Salmonella typhimurium TA98 and TA100.
