This study was performed to investigate the changes of the hematological and hepatic function in the mouse after the adminstration of Bambusae Caulis in Liquamen extracted by a different refining process during 30 days. The experimental groups divided seven. Control group was administered mice with 0.9％ saline(4mL/kg). The experimental groups were divided 10％ bamboo extract(B1, C1 and D1 experimental groups) and 30％ bamboo extract(B2, C2, D2 experimental groups)administered groups(4mL/kg). Hematological results: RBC(P<0.05) and Hct(P<0.05) were significantly decreased in the D2 group. The activity of transaminase(P<0.05) of D2 group was significantly increased, but the activities of SOD(P<0.05) and catalase(P<0.01) were significantly decreased, in the D group. Histopathological observation: Ballooned hepatocytes were occurred periportal vein in the D1 and D2 groups, and necrosis of hepatic nuclei in the D2 group were observed. The results indicated that hematological and histopathological toxicity were occurred in the administered group of bamboo extract D refined by 2 times distilling at $108{\circ}C$.

The rising concentration of atmospheric carbon dioxide is causing ocean acidification and global warming. The seahorse is an important species in marine ecosystems and fishery markets, however, their populations have recently decreased due to ocean acidification. As a result, we examined changes in the physiological responses of the spotted seahorse Hippocampus kuda when it was exposed to acidic sea water (pH 6.0, 6.5, and 7.0) and normal seawater (pH 8.0 as the control) over a period of 15 days. As the pH decreased, the seahorses' body weight and length also decreased. Components in body of ash, the crude lipids and crude proteins also differed significantly with changes in pH, due to stress caused by the seahorses' exposure to the acidic water conditions. The superoxide dismutase levels were significantly lower in the pH 6.0 and 6.5 groups than they were in the pH 7.0 and pH 8.0 groups. However, the catalase and glutathione levels were significantly higher in the acidic sea water groups. We suggest that decreasing the pH level of rearing water induces a stress response in H. kuda, damaging their ability to maintain their homeostasis and energy metabolism. Antioxidant enzymes are generally sensitive to acidic stress; in this study, the antioxidant activity was significantly affected by the pH level of the rearing water. These results indicate that physiological stress, induced by exposure to acidification, induces an antioxidant reaction, which can reduce general components in the body and the growth of H. kuda.

최근 초지중심 사양형태의 증가와 초지면적의 확대에 따라 단순한 사료로서가 아니라 영양가치가 높고 기호성이 높은 목초생산이 요구되고 있다. 그러나, 고위생산을 위해 다량으로 사용된 질소질비료에 의하여 질산태 중독 등의 문제가 야기되고 있어 목초의 생리 및 영양에 관한 연구가 필요하게 되었다. 사료성분 혹은 영양가치에 대한 연구는 이미 일찍부터 다루어져 왔으나, 주로 야초류, 청예작물 및 농가부산물 등의 일반성분 특히, 조단백질과 조섬유함량의 연구가 주가 되었고 다년생 목초류에 대한 연구는 1975년경부터 본격화 되기 시작하였다. 그동안 한국초지학회지와 축산학회지($1972\sim1991$)에 게재된 총 151편의 생리 및 영양에 관한 연구 중에서 다년생 목초류를 취급한 것은 불과 63편에 머물고 있다. 이 분야의 연구는 각종 목초 사료작물에 대한 재배조건과 생육단계에 따른 생리생태학적 연구와 사료성분, 소화율 및 가소화양분 함량의 일반적인 변화, 경향을 검토하여 사료 가치 평가를 위한 기준으로 삼았다. 그러나 다년생 목초류는 물론 사료 작물에 있어서 육종 생리분야의 연구는 매우 미흡한 상태로써 단지 발아, 생육, 저장탄수화물 및 유독성분 등 단편적인 연구만이 행해지고 있을 뿐이다. 또한 사료 성분이 가축의 기호성에 미치는 영향을 구명하기 위한 연구는 거의 이루어지고 있지 않으므로 금후 탄수화물과 미량 요소에 대한 자세한 연구 검토가 필요하다고 생각된다. 특히 목초와 사료작물의 화학적인 조성과 가축의 생리에 관련한 여러가지 문제들도 앞으로 보다 깊이 연구되어야 할 과제라고 생각된다.권을 잡기 위해 10년지기였던 IBM과 MS사는 각각 OS/2와 윈도즈를 내세우고 양보할 수 없는 힘겨루기에 들어갔다. 또 이들 양사는 펜컴퓨터,멀티미디어등 차세대제품의 운영체제 시장을 둘러싸고 일찍부터 격전에 들어갔으며 IBM과 MS사의 혼전을 틈타 썬마이크로시스템을 필두로한 워크스테이션 업체 및 유닉스진영까지 고성능 PC시장을 겨냥한 OS를 속속 개발, 90년대의 OS 전쟁은 한치 앞을 내다볼 수 없는 안개국면으로 접어들고 있다.

In order to investigate the immune response induced by supplementation of herb medical stuff in diet on the nile tilapia. Oreochromis niloticus, experiments were performed with feeding of four different experimental diets supplemented with 2% ginseng. Panax ginseng, 3% Kugija. Lycium chinense, 3% Hasuo, Polygonum multiflorum, 2% Omija, Schizandra chinensis, respectively, for 84 days. The non-specific immune responses changed during the feeding period were investigated at 2, 4, 6, 8, 10, 12 weeks in each group. Average body weight of the nile tilapia with supplemented diets was heavier than control group. The fish fed on diet supplemented with 3% Kugija showed the better growth than the other tested groups. Complement activity such as complete hemolytic activity ($CH_{50}$) and bactericidal activity against Escherichia coli tended to be increased by the supplementation of herb medical stuff. The lysozyme activity of serum and adherent phagocyte activity showed higher in the fish fec on diet supplemented with 3% kugija than the other tested groups. In respect to the RPS against experimental Edwardsiella tarda infection, all of the group fed on the herb medical stuff in diet appeared higher response compared with control group. From these results, herb medical stuff (Panax ginseng, Lycium chinense. Polygonum multiflorum, Schizandra chinensis) might be used a additives of diet for the increasing of non-specific immune response or resistance against bacterial fish diseases.

Purpose: We have evaluated changes of body composition for patients that underwent a radical gastrectomy for stomach cancer by the use of available bioelectrical impedance analysis during the first year following surgery. We plan to utilize these findings in nutritional and physiological studies. Materials and Methods: We evaluated clinical changes in body composition in patients using the bioelectrical impedance method (Inbody 4.0, Biospace, Korea), between November 2003 to November 2004. A total of 98 patients agreed to enroll in this study among all of the patients that underwent a radical gastrectomy. Results: The average weight decreased by 6.7%, and 9.4%, within the first and 6 months after surgery, respectively (P<0.01). The fat free mass (FFM) dropped by 4.9% within the first month and there were no more changes after this period (P<0.01). The fat mass (FM) and visceral fat area (VFA) decreased 24.3% and 14.1% within the first 6 months (P<0.01), respectively. The reduction effects for female patients were greater than for male patients for weight, FFM and VFA (P<0.05). The edema index was higher in patients with stage III-IV disease than in patients with stage I-II disease (P<0.05). There were significant differences for Billroth I and Billrothl II patients as compared to patients that underwent an esophagojejunostomy for a reduction of the FM, as measured in the in the 12th month after surgery (27.6%, 22.1%, and 41.2%, respectively; P<0.05). Conclusion: Since nutritional supplementation and an improvement in body weight loss after a radical gastrectomy is significantly related with quality of life, nutritional and physiological studies should be greatly considered. In this study, bioelectrical impedance analysis was very useful in analyzing the diminution of body composition and we hope this study on the nutritional and physiological aspects related to a radical gastrectomy will be useful for later studies.

Many cellular phone volunteer studies have been conducted since such a social issue is raised that the long time usage of cellular phone by teenagers may increase health risk. While there were various adult volunteer studies using GSM cellular phone on heart rate and blood pressure, very few teenager studies using CDMA phone were conducted. In this study, two volunteer groups of 21 teenagers and 21 adults were exposed to 300 mW CDMA wave for half an hour, and the physiological parameters such as blood pressure, heart rate, respiration rate, and skin impedance were investigated. All the parameters fur both groups were unaffected during exposure except the skin impedance of teenager group.

Pain is subjective and greatly influenced by prior experiences, but it is real. Pain associated with an organic(objective) pathology is more easily explained and treated. However, atypical or unexplainable pain is usually a source of greater confusion and frustration. Pain may be divided into four general diagnostic categories. 1) pain with anatomic features and objective findings 2) pain with anatomic features and without objective findings 3) pain with non-anatomic features associated with stress and somatization 4) pain with non-anatomic features associated with perceived physical injury. There is a well-established relationship between emotional, physical and/or sexual abuse history and development of chronic pain. It has been suggested that the link between somatization and abuse involves a paradoxical pattern of hiding feelings and reality, while seeking acknowledgment of suffering. History of abuse may physiologically and developmentally increase a person's susceptability to pain and organic changes can be associated with psychogenic disease. Patients with chronic pain should be treated with multidisciplinary approaches including exercise, meditation, cognitive therapy, medications, and biofeedback. Cognitive therapy alters patient's cognition and management of pain and alleviates pain, especially associated with stress. Antidepressants are the most commonly used medications and pain control effects have no relation with mood changes. Biofeedback with relaxation training, exercise and meditation may also be effective in pain control.
