The study carried out to investigate the effect of noise levels on the production of layers indicated that the 83.67% and 79.17% egg production of layers affected with the 75 db and 100 db noise levels, respectively, were reduced upto 1.6 and 6.4 respectively, compared with the 84.56% egg production of layser treated with no noise. Egg weight was lowest in layers treated with 100 db noise levels. egg production (80.30%) and egg wight (60.87g) of layer group treated with Anti sound were higher than egg production (79.40%) and egg weight (59.95g) of layer group treated with general noise.

This study investigated the immunostimulatory effect of enzymatic porcine placental hydrolyzate (EPPH) in cyclophosphamide (Cy)-treated rats. This effect of EPPH prevented Cy-induced decreases in body, spleen, and thymus weights and natural killer (NK) cell activity. The numbers of immune cells, such as white blood cells, granulocytes, and lymphocytes, and mid-range absolute counts were significantly higher compared to the control group. The levels of tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, IL-2, IL-12, and immunoglobulin G (IgG) were notably reduced by Cy, while EPPH prevented these effects. Histopathological analysis of spleen samples revealed the protective effect of EPPH against Cy-induced immunosuppression. The findings demonstrate that EPPH can alleviate immunosuppression by cell viability, tissue damage, and regulation of the levels of cytokines. EPPH may have value as a component of immunostimulatory agents or an ingredient in functional foods.

To observe antibody changes after praziquantel treatment in paragonimiasis, a total of 46 serum samples from 13 serologically diagnosed patients was collected for 4~28 months. The specific antibody (IgG) levels were measured by enzyme- linked immunosorbent assay (ELISA). All but one patient who needed retreatment became symptom-free within a week. Antibody levels were dropped near to or below a cut-off absorbance (abs.) of 0.25 in varying intervals from 4 to 18 months. Of 9 patients who were retested within 3 months, 5 revealed temporary elevation of antibody level. After the elevation, the levels be낙an to decline slowly to negative ranges. If treated earlier after symptoms developed, the temporary elevation did not occur and intervals to negative conversion were shorter. By sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) /immunoblot, antigen-antibody reactions in individual patient faded gradually without significant changes in reacting antigen bands.

Severe cytomegalovirus (CMV) infection involving multiorgan is very rare except in very low-birth weight infants, or in immunocompromised pediatric patients. We report an unusual case of severe CMV infection involving multiple organs including the central nervous system, liver, lung, and gastrointestinal tract in a late-preterm infant at 2 months of age.

The number of immunocompromised patients has increased over the past decades due to HIV infection, solid and stem cell transplantation, intensified chemotherapy and treatment of autoimmune disease. Pneumonia is a major cause of both morbidity and mortality in immunocompromised patients. Clinical management of pneumonia is difficult, since differential diagnosis in this setting is broad and includes both infectious and noninfectious processes. Because the development of pneumonia in immunocompromised patients is frequently life threatening, early therapeutic and diagnostic intervention is essential to obtain better outcomes.

생체내 기능조절에 중요한 역할을 하는 prostaglandins(PGs)는 신경계 세포, 순환기계세포, 거삭세포, 섬유아세포 및 암세포 등 여러 부위에 널리 분포되어 있다. 본 연구에서는 PGs생체내 전구체인 arachidonic acid와 구조유사체인 eicosapentaenoic acid(EPA) 및 docosahexaenoic acid(DHA)에 의한 순환기계효과를 TXA$_2$ 생합성과 관련하여 규명하고져 하였다. 또한 여러 가지 면역요법 중 암세포 살해능이 있는 lymphokine activated killer(LAK) 세포의 생성력과 생체내 면역세포 중 암세포의 일차적인 방어작용을 하는 것으로 알려진 natural killer(NK) 세포의 활성도를 PGs생성과 연관시켜 검토하므로써 암환자에 저하되어 있을 면역기구와 PGs와의 상관관계를 규명하고자 하였다.

This study aimed to identify the effect of chronic mind-body function decline on health-related activities of daily living. Data collection was surveyed using interview and questionnaires by 148 subjects in a general hospital located in Seoul from June 8 to July 13, 2011. The results were as follows: First, based on exercise habit, patient group who do exercise regularly showed in male(26.7%) and female(22.7%), respectively. The risk ratio of it was 0.25 times. On the other hand, control group who do exercise regularly showed in male(42.2%) and female(31.8%), respectively. The risk ratio of it was 0.61 times. Secondly, the risk ratio of social factor in male was 45.18 times(p=.04) while the risk ratio of physical factor in female was 237.1 times(p=.001). In conclusion, to prevent declining of chronic mind-body function, it is necessary to solve stress through sound life rhythm maintenance, immunity enhancing food intake and continuous exercise.

해마다 설 연휴 즈음 급증하는 수인성 전염병. 해외 여행객 증가, 국내 유동인구 증가, 피곤으로 인한 면역력 저하, 오염된 음식물 공동 섭취 등이 주요 원인으로 꼽힌다. 주변에서 쉽게 감염될 수 있는 수인성 전염병을 알아보고 수시로 손을 씻는 등의 개인위생수칙을 잘 지켜나가는 것이 예방의 지름길.

무더운 여름 날씨가 끝나면 낮과 밤의 일교차가 큰 환절기인 가을철을 맞이하게 된다. 특히 면역능력과 체력이 낮은 어린 가축들은 환경(온도, 풍속, 습도 등)의 변화에 의한 대사불균형 스트레스를 받기 때문에 각별한 관리를 통해 생산성 저하와 질병을 예방해야 한다. 아침 저녁으로 바깥의 찬 공기에 노출되지 않도록 차단하며, 낮에는 충분히 환기를 해주고, 밤에는 보온이 되도록 한다.

유난스러웠던 꽃샘추위 때문에 힘들었던 시간이 지나고 햇살이 따스한 것이 어느새 봄은 한 걸음 더 우리에게 다가와 있다. 덕분에 움츠러들었던 몸도 풀리고 기분도 상쾌해지고 있지만, 기온 변화와 공기의 상태에 민감한 우리 호흡기는 제 리듬을 찾지 못하고 힘겨워하기 일쑤다. 노인들의 경우에는 면역력이 저하되고 있고, 호흡기 자체에도 노화가 오기 때문에 계절이 바뀌는 요즘 같은 환절기에는 특히 건강을 잘 챙겨야 한다.
