The most remarkable aspect in the hormesis law is that dose of harmful agents can produce effect that are diametrically opposite to the effect found with high doses of the same agent. Minute quantities of a harmful agent bring about very small change in the organism and control mechanisms appear to subjugate normal processes to place the organism in a state of albert and repair. The stimulated organism in more responsive to changes in environmental factors than it did before being alerted. Routine functions, including repair and defense, have priority for available energy and matetial. The alerted organism utilizes nutrients more efficiently, grows faster, shows improved defense, and lives longer. Accelerated germination, sprouting, growth, development, blooming and ripening, and increased crop yield and resistance to disease are found in plants. Another concept supported by the data in that low doses of ionizing radiation provide increased resistance to subsequent high doses of radiation. The hormesis varies with subject plant, variety, state of seed, environmental and cultural conditions, physiologic function measured, dose rate and total exposure. The results of hormesis are less consistently found, probably due to the great number of uncontrolled variables in the experiments. The general dosage for radiation homlesis in about 100 (10 to 1,000) times ambient or 100 (10 to 1,000) times less than a definitely harmful dose, but these must be modified to the occasion. Although little is known about most mechanisms of homzesis reaction, overcompensation of repair mechanism is offered as one mechanism.

The purpose of this study was to investigate conception of children's hospitalization stress and to make clear concepts, and to use Walker & Avant's concept analysis method. Children's hospitalization stress attributes were derived from physiological changes, individual-environmental interactions, cognitive and psychosocial developmental stage responses, and intrinsic and outward changes due to coping styles. The prerequisites for hospitalization stress of children were disease severity, biological factors, and support system, and the results were hospitalization adaptation, disease and health recovery, improvement of child development, and acquisition of coping skills. In order to solve the prerequisites for Hospitalization stress of children, it is necessary to be aware of the disease and to establish a support system of parent-family. Afterwards, we suggest more qualitative research on the hospitalization stress of children, the development of tools that reflect the characteristics of the hospitalization stress of children, and the development of programs to solve the Hospitalization stress.

Chronic kidney disease can be treated if it is detected early, but as the disease progresses, it becomes impossible to recover. Finally, renal replacement therapy such as transplantation or dialysis should be used. Ultrasonography is used to diagnose kidney cancer, inflammatory disease, nodular disease, and chronic kidney disease. It is used to identify information about degree of inflammation using information such as kidney size, internal echo characteristics. Currently, the degree of disease in the clinic uses the value of glomerular filtration rate. However, even in ultrasound, changes in the degree of inflammation and disease can be observed. In this study, we used ultrasound images to quantify the changes in brightness, size, cortex, and subclinical changes of the kidney with progression of the disease, and compared them with the glomerular filtration rate used in clinical practice. In 105 cases, we performed 35 cases of normal kidney, 35 cases of early kidney disease, and 35 cases of terminal kidney. The brightness of the cortex of the image was obtained and the difference in brightness between the cortex and the proximal portion was obtained by the slope. The graph of the portion which was not smooth due to the ultrasonic characteristics was used as the function regrass. The size reduction was obtained from the original data. The results were as follows: It was proportional to the glomerular filtration rate. It is considered that the algorithm can be applied to the disease if the algorithm study continues.

This study estimated the degree of uterine inflammation and resumption of ovarian cyclicity in postpartum dairy cows. In addition, the prevalence of health problems during calving and the postpartum period was investigated. A total of 224 Holstein dairy cows from four dairy farms in Chungcheong Province were used for the study. Uterine discharge was scored on a 0 to 5 rank scale (metricheck score) using a metricheck instrument from 1 to 8 weeks postpartum and uterine cytology (neutrophil level) was examined at 4, 6 and 8 weeks postpartum to evaluate uterine inflammation. Resumption of ovarian cyclicity was evaluated based on progesterone analysis (${\geq}1ng/mL$) at 4, 6 and 8 weeks postpartum. Postpartum disorders were diagnosed by veterinarians in the research team. The metricheck score decreased linearly (p < 0.0001) from weeks 1 ($3.4{\pm}0.1$) to 4 ($2.0{\pm}0.1$) postpartum, and then remained at that level through week 8 postpartum ($1.6{\pm}0.1$, p > 0.05). The neutrophil levels determined by uterine cytology assays also decreased (p < 0.0001) from week 4 ($22.3{\pm}1.8%$) to 6 ($12.1{\pm}1.4%$) postpartum, and then remained at that level through week 8 postpartum ($9.2{\pm}1.4%$, p > 0.05). The proportion of cows exhibiting the ovarian cyclicity increased linearly (p < 0.0001) from weeks 2 (12.1%) to 8 (74.3%) postpartum. The prevalence of dystocia and retained placenta were 20.5% and 30.4%, respectively. The prevalence of ketosis, milk fever, abomasal displacement, septicemic metritis, endometritis, subclinical endometritis, pyometra, and ovarian cysts were 18.8%, 3.6%, 4.0%, 36.2%, 29.5%, 17.0%, 4.5%, and 14.7%, respectively. The prevalence of digestive problems and mastitis were 5.4% and 9.6%, respectively. The prevalence of culling and death were 4.0% and 3.6%, respectively. The prevalence of dystocia, retained placenta, septicemic metritis, endometritis, ovarian cysts, digestive problems, mastitis, and culling differed among farms (p < 0.05 to 0.01). In conclusion, proper examinations for uterine inflammation and ovarian cyclicity during 4 to 8 weeks postpartum are useful clinical tools to maintain herd reproductive health. Dystocia, retained placenta, septicemic metritis, and endometritis were predominant disorders in dairy cows of the survey area.

GABA(감마-아미노부티르산)는 최근 식품업계에서 특히 주목되고 있는 기능성 성분의 하나이다. 제42회 일본 인간건강진단학회(2001년 8월 30일 개최)에서 발표된2000년도의 인간건강진단 전국집계를 살펴보면 약 85%에 어떤 이상이 인지되었고, 그중에서 특히 식생활 습관과 깊은 관계가 있는 간기능이상, 고콜레스테롤, 비만, 고중성지방, 고혈압의 예비군이 일제히 높아지고 있음을 알 수 있다. 더구나 이 현상은 매년 증가 경향에 있어 확실히 염려해야 하므로 이대로 방치해서는 안 된다. 통상 인간의 체내에 존재하고 있는 물질이 어떤 원인으로 결핍되어 적어도 위에서 언급한 바와 같은 질병을 일으키는 원인이 된다면 그 성분을 보급하는 것이 가장 중요하다. GABA를 함유한 식품이 특히 각종 (식)생활습관병의 예방.회복에 위력을 발휘한다는 것이 차차 밝혀지게 되어 뜨거운 기대가 모아지고 있으며, 각 방면에서 GABA를 증강시킨 기능성식품의 개발이 진행되고 있다. 여기서는 지금까지 GABA의 판명된 효능과, 그리고GABA함유 제품을 살펴보고 아울러 이에 대한 장래의 전망도 고찰해 본다.

골관절염은 관절연골의 퇴행성 변화로 연골기질의 분해로 인하여 연골 강도와 cushion으로서의 능력이 감소되는 질환이다. 골관절염의 대부분 약물치료는 통증과 염증을 감소시키는 목적으로 사용되며, 근본적인 치료효과를 주는 약물은 현재까지 개발되어 있지 않다. 영양약학 제품에 대한 질병의 예방적, 치료 보조적 차원에서 인체에 대한 기초적인 생리활성의 중요성을 인식하게 됨으로써 그 역할이 중요하게 인식되고 있다. 특히, 골관절염 치료에 쓰이는 glucosamine은 proteoglycan (PG)와 glucosaminoglycans(GAGs)의 합성의 전구물질로서 연골세포 생성을 자극하며, 통증, 염증의 경감 및 진행과정을 억제시키고, 관절기능 회복을 촉진하는 것으로 알려져 있다. 그러나 glucosamine이 어떤 기전에 의해 관절연골세포에 직접적인 영향을 주는지 밝혀져 있지 않다. 본 연구에서는 glucosamine sulfate가 연골세포에 미치는 영향을 규명하고자 하였다.

21세기 양돈산업의 전망은 환경문제, 사료생산, 동물복지 등 다양한 생산제한 요인에 의하여 국제적으로 돈육수급이 불안정할 것으로 예상되지만, 세계적으로 돼지고기 소비는 아시아 지역의 경기회복 등으로 증가추세에 있어 우리의 노력 여하에 따라서는 내수 소비확대 및 수출재개 등 경쟁력 있는 양돈산업으로 발전될 수 있다고 생각합니다. 또한 미래의 양돈산업 전개방향은 소비자 중심의 산업으로 변화되어 돈육의 건강개념과 영양적 가치 증진 및 식품의 안전성에 중점을 둘 것이며, 특히 소비자의 의식변화는 미래 양돈산업을 지배하는 결정적인 요인이 될 것입니다. 한편 유통경영 측면에서는 수직협력 시스템(Vertical co-ordination)과 효율적인 물류유통관리(MSCM) 시스템 도입이 가속화 될 것입니다. 즉, 소비자가$\codt$저마진에 의한 다량판매, 대규모 사육, 생산비 절감 기술개발에 주력할 것이라고 생각됩니다. 이에 따라 우리나라 양돈산업의 국제경쟁력 제고를 위하여 보다 시급히 해결되어야 할 질병$\codt$방역관리, 유통구조 개선, 고품질 돈육생산 및 위생$\codt$품질향상 분야에 있어서 중점 추진되어야 할 내용을 소개하고자 합니다.
