Pigs have been used widely in biomedical research owing to their physiologic and anatomic similarities to humans. Analysis of the hematologic and biochemical values in pigs is an important basis for biomedical research and veterinary clinical diagnosis, but research on transgenic pigs has been sparse. This study was conducted to obtain basic data on transgenic pigs and to describe and compare the reference values for hematologic and biochemical parameters in human tissue plasminogen activator (htPA) transgenic pigs vs normal pigs. Blood samples were obtained from 7 normal LY (Landrace-Yorkshire crossbred) pigs and 8 transgenic pigs and 16 hematologic and 15 serum biochemical parameters were tested. Among the hematologic parameters tested, significant differences were observed in the red blood cells (RBC), mean red blood cell hemoglobin (MCH), and lymphocytes (LYM), between the non-transgenic and transgenic pigs. Among the biochemical parameters tested, the blood urea nitrogen (BUN), total protein (TP), cholesterol (CHOL), alanine aminotransferase (ALT), creatinine (CREA), gamma glutamyl transpeptidase (GGT), globin (GOB), and amylase (AMYL) showed significant differences between the two groups. Thus, the values determined in this study can be used as basic reference values for transgenic pigs and will contribute to their use in biomedical research.

엄지발가락이 따끔거리더니 시간이 지날수록 심한 통증이 찾아와 밤에 잠을 잘 수 없는 고통을 겪는 40대가 많다. 한참 사회생활이 활발한 40대의 특성상 술자리가 많고 외근도 잦아 걷는 일이 다반사인데 신발을 신지 못할 정도의 심각한 통증으로 업무에 지장이 생겨 참다못해 병원에 방문하면 혈액검사를 비롯한 검진을 통해 급성 통풍암을 알게 된다.

본문에서는 현재 주로 사용되고 있는 혈청학적 방법을 주로 소개하고자 한다. HIV 감염의 특성상 헌혈 혈액 등과 같이 많은 시료를 신속하게 검사하여야 하고 또한 검사결과가 개인에게 매우 중요한 의미를 지니므로 HIV에 대한 혈청학적 검사는 일차적으로 민감도가 높은 검색용 검사를 우선 시행하고 이차적으로 특이도가 높은 확인용 검사를 실시하여 판정하는 것을 원칙으로 하고 있다.

Purpose : Airway inflammation is considered to be a characteristic feature of asthma, and eosinophils are recognized as the most important inflammatory cells. This study aims to assess the importance of blood eosinophil count and serum eosinophil cationic protein(ECP) levels as a noninvasive marker of bronchial hyperresponsiveness(BHR) in children with suspected asthma. Methods : This study used data from 87 subjects with asthma-like symptoms(6-18 years old). The $FEV_1$ and provocative concentration producing a 20% fall in $FEV_1(PC_{20})$ on methacholin inhalation challenge test were measured. Four groups were classified based on $PC_{20}$[Group I : <2 mg/mL; Group II : 2-8 mg/mL; Group III : 8-18 mg/mL; Group IV : (18 mg/mL], and blood eosinophil count and serum ECP levels were analyzed. In addition, subjects were classified based on the cutoff value of $PC_{20}$(BHR positive group : <18 mg/mL; BHR negative group : (18 mg/mL). Then blood eosinophil count and serum ECP level were compared between these two groups. Results : Likelihood ratio test for trends revealed a significant association between the blood eosinophil count or serum ECP level, and the degree of BHR as measured by methacholine $PC_{20}$. Blood eosinophil count or serum ECP level was significantly higher in the BHR(+) group than in the BHR(-) group. Blood eosinophil count had a positive correlation with serum ECP level. Conclusion : Blood eosinophil count and serum ECP level may be a useful non-invasive clinical marker of BHR in subjects with suspected asthma. This supports the hypothesis that BHR in asthma is a consequence of airway eosinophilic inflammation.

고양이 말초혈액 다형핵백혈구 (PMN)의 유주활성에 있어서 계난백유래물질 (EWD)의 면역증강 효과를 검토하였다. PMN의 유주활성은 EWD 그 자체 및 EWD로 배양한 PMN의 배양상층액에서는 활성이 존재하지 않았다. 그러나 EWD로 배양한 MNC 배양상층액에서는 PMN에 대한 유주활성이 증가되었다. 본 활성은 checkerboard assay를 통해 진성 유주활성으로 밝혀졌다. 이러한 고양이 PMN 유주활성은 human recombinant interleukin-8(hr IL-8)에 의해서도 증가되었다. IL-8의 또 다른 특성인 세포 형태변형 실험에서도 EWD로 배양한 MNC의 배양상층액과 hr IL-8 모두에서 높은 수준의 세포 형태변형효과를 나타내었다. 이와 같이 EWD로 배양한 MNC의 배양상층액과 hr IL-8 모두에서 증가된 PMN의 유주활성 및 세포변형효과는 anti-human IL-8mAb에 의해 농도의존적으로 억제되었다. 이상의 결과로부터 EWD는 고양이 PMN의 유주활성에 있어서 면역증강 효과가 있으며, 이것은 EWD에의해 활성화된 MNC에서 분비되는 IL-8양 유주성 인자에 의해 PMN의 유주활성 증가 및 세포 형태 변형이 일어나는 것으로 사료되었다.

Hemodialysis is essential for patients with end stage renal failure. It is important to improve the patency rate and to minimize occurrence of the stenosis. Also, the blood flow to the artificial kidney can affect the blood flow characteristics through arteriovenous graft. Thus, the delivered dose are important factors for analyzing hemodynamic characteristics during hemodialysis access. In this study, the numerical analysis was performed for the effect of the delivered dose during hemodialysis access on the blood flow through the graft. As a result, The adverse pressure gradient occurred in case of a larger delivered dose through a catheter than standard dose and the flow instability increased. Also the circulation flow appeared largely at anastomotic site of the vein when the delivered dose was exceeded about half blood flow of inlet blood flow.
