This study was conducted to evaluate the effects of duck-meat consumption on adult disease risk factors, including body compositions, hematological variables, and serum metabolic and lipid profiles in adult human males. To obtain results, 20 adult males aged 20 to 25 were subjected to a diet of 600 g/day of duck-meat for 4 wk, after which body composition, hematological variables, and serum metabolic and lipid profiles were investigated to determine if there was a relationship between duck-meat consumption and adult disease risk factors. The results revealed that high amounts of duck-meat intake did not negatively alter body indices such as body weight, fat mass, body mass index (BMI), % body fat or waste-to-hip ratio (WHR). Furthermore, there were statistically insignificant changes in the number of blood cells, although this number did increase significantly following intake of duck-meat. Moreover, general decreases in serum metabolic parameters were observed, but none of these changes were significant with the exception of the concentration of blood urea nitrogen (BUN). The serum concentrations of LDL-cholesterol also showed a statistically significant decrease by 5.86%. Therefore, this study suggests that the ingestion of duck-meat not only significantly increased the RBC count but also decreased BUN and LDL-cholesterol concentrations in adult males.

The microdilution assay recommended by NCCLS (National Committee for Clinical Laboratory Standards) is one of the standardized methods of antibiotic susceptibility test. This method has been widely used clinically to obtain MIC values of antibiotics on pathogenic microorganisms. It is more convenient, rapid and simple to test many samples than other test methods such as agar diffusion assay and broth macrodilution assay. The screening of antimicrobial agents from microbial extracts is too laborious in its process. Therefore, a number of screening methods having more simple procedure have been developed. In our laboratory, we applied microdilution assay for screening the antimicrobial agents. This assay showed dose-response results and was more sensitive than disc diffusion assay in our system. We tested 200 samples of microbial extracts originated from 100 microbial strains and selected several samples as potential candidates. In this report, we show that the microdilution assay is more convenient method in screeing of antibiotic susceptibility than those previously reported.

Background : Polymerase-chain reaction (PCR) detection is useful to diagnosis of pertussis at initial stage because the growth rate of Bordetella pertussis (B. pertussis) is relatively slow. Currently, the primer set for the insertion sequence IS481 (BP primer) is used widely for PCR detection of B. pertussis. However, the cross-reactivity of BP primer set with Bordetella holmesii (B. holmesii) was reported recently. Therefore, discrimination of B. pertussis and B. holmesii is needed in PCR step. For this reason, we developed new primer sets based on 16S rDNA sequence for diagnostic use and estimated the efficiency of these new primer sets. Materials and Methods : The specific PCR primers were designed from the aligned sequence matrix of 16S rDNA genes of various Bordetella species. The specificity of designed primers were estimated using clinically important 4 Bordetella species, B. pertussis, B. holmesii, Bordetella parapertussis (B. parapertussis) and Bordetella bronchiseptica (B. bronchiseptica). The sensitivity to B. pertussis of designed primers was also estimated and compared with BP primer set. Results : As the results, the developed new primer set successfully distinguished B. pertussis and other Bordetella species containing B. holmesii. In the sensitivity assay, the detectable limits of 16S-F2/16S-R1 primer set for B. pertussis were revealed as 5 pg of genomic DNA and 10^5 cells/mL of cell suspension, In addition to these, identical results between BP with primer and new primer were obtained in clinical samples. Conclusion : In this study, the specific primer set for B. pertussis was developed based on 16S rDNA sequence and this primer set did not show cross-reactivity to B. holmesii. In addition to these, the applicability of this primer set to the clinical specimens was also confirmed. 목적 : 백일해의 원인균인 B. pertussis는 성장속도가 늦기 때문에 PCR 검출방법은 백일해 진단의 초기단계에서 유용하다. 현재 BP primer가 PCR 검출에 광범위하게 사용되나 BP primer는 최근에 B. holmesii와의 교차반응성이 보고되었다. 따라서 PCR 단계에서 B. pertussis와 B. holmesii이 감별이 필요하다. 이러한 이유로 본 논문에서는 16S rDNA sequence를 기반으로 하는 진단용 primer를 새로 고안하였고, 그 효용성을 측정하였다. 재료 및 방법 : 특이적 PCR primer들은 다양한 Bordetella 속의 16S rDNA 유전자들의 정렬된 서열 집합체로부터 고안되었다. 고안된 primer의 특이도는 임상적으로 중요한 4개 Bordetella 종 (B. pertussis, B. holmesii, B. parapertussis, B. bronchiseptica)을 사용하여 평가하였다. 민감도 또한 평가하였고 그 결과를 BP primer와 비교하였다. 결과 : 결과적으로, 새롭게 개발된 primer는 B. holmesii를 포함하는 다른 Bordetella 종들로부터 B. pertussis를 성공적으로 감별하였다. 민감도분석에서는 B. pertussis에 대한 16S-F2/16S-R1 primer의 검출한계는 5 pg의 genomic DNA와 10^5 cells/mL의 세포부유액까지 였다. 또한 임상검체에 대해서 BP primer set와 동일한 결과가 확인되었다. 결론 : 본 연구에서 오직 B. pertussis에 대해 특이적인 PCR primer를 16S rDNA를 기반으로 하여 개발하였고, 이는 B. holmesii와의 교차반응성을 나타내지 않았다. 또한 본 연구에서 새롭게 개발된 primer의 임상검체에 대한 적용성도 확인되었다.

간문맥 동맥류는 흔치 않은 질환으로 증상 없이 우연히 발견되는 경우가 많다. 정확한 원인은 아직 밝혀지지 않았으며 다양한 모양을 갖고 있다. 기저 간질환이나 문맥압 항진의 증거가 없는 간문맥 동맥류는 비교적 안정적인 경과를 보이는 것으로 알려져 있다. 따라서 조기 진단 후 추적검사를 통해 크기 변화와 합병증 발생 여부에 대한 관찰이 중요하다. 증상이나 합병증이 발생한 경우 중재적 시술이나 수술적치료가 필요하다. 저자들은 비특이적인 복부 불편감을 주소로 내원한 환자에서 CT상 간외 간문맥 동맥류를 발견한 1예를 경험하였기에 문헌고찰과 함께 증례를 보고하고자 한다. Portal venous aneurysm (PVA) is an unusual venous malformation and its etiology is not fully understood. Most PVAs are diagnosed incidentally by non-invasive abdominal imaging techniques; indeed, recently, PVAs have frequently been discovered in this way. Most PVAs remain stable, without complications, in patients with no clinical symptoms of portal hypertension or intrinsic liver disease. However, if PVA is discovered in these patients by chance, close imaging follow-up of portal vein aneurysms is recommended. In the case of aneurysm growth or the development of complications related to the aneurysm, medical or surgical approaches are advised but there is no consensus on the use of prophylactic antiplatelet or anticoagulation medications. We report a case of incidental PVA identification in a patient without underlying liver disease by routine investigation. A review of the literature is also provided. (Korean J Med 2013;85:294-296)
