This study examined the partial replacement of the fish meal with meat meal in practical diets for juvenile rock-fish. Five isonitrogenous (48% CP) diets were prepared to contain meat meal at 0% (control), 10%, 20%, 30% and 40% with substituting the mackerel meal in the control diet. Three replicate groups of fish (initial average weight, 4.1g) were hand-fed to visual satiety two times daily for 8 weeks. Survival (>93%) and daily feed intake were not significantly different (P>0.05) among treatments. The best weight gain, feed efficiency and protein efficiency ratio were obtained from fish fed the diets containing 0% and 10% meat meal, and were not significantly different (P>0.05) to those of fish 134 diet containing 20% meat meal. Condition factor, visceralsomatic index and hepatosomatic index were not influenced by dietary meat meal levels. The contents of crude protein and ash of whole body were not significantly affected (P>0.05) by dietary meat meal levels, whereas crude lipid content of fish fed the diets containing 30% and 40% was lower than that of fish fed the control diet. Proximate composition of liver was not influenced by dietary meat meal level (P>0.05). The data obtained in this study indicate that a diet containing $10{\sim}20%$ meat meal could be used for least-cost formulation in juvenile rockfish diet.

A total of twenty-four multiparous sows (Landrace × Yorkshire) and their litters were used in this 21-day experimental trial. Based on their body weight, sows were randomly allocated into one of three treatments with eight replicates. The dietary betaine supplementation contained three levels: (i) CON (Basal diet + 0% Bet), (ii) Bet 0.05% (CON + 0.05% Betaine), and (iii) Bet 0.15% (CON + 0.15% Betaine). The supplementation of betaine had no effect (p > 0.05) on body weight and feed intake of lactating sow. Moreover, no significant response was observed on backfat thickness, body condition score, and weaning of the estrus interval with the dietary supplementation of betaine. In addition, the litter weaning weight, litter weight gain, average litter daily gain, and survivability rate at birth showed no significant difference with the dietary betaine supplementation of the sow diet. Fecal scores of the lactating sows and suckling piglets were not affected (p > 0.05) with the dietary betaine supplementation compared with the control diet during the experimental periods. The findings of this study showed that betaine supplementation does not boost growth performance, feed intake, body conditions, and fecal score in lactating sows and suckling piglets fed a corn-soybean meal-based diet.

This study was conducted to effect of extruded pellets (EPs) and moist pellet (MP) diet on growth and fish health parameters in farm cultured olive flounder Paralichthys olivaceus. Two replicate groups of 2,600 fish per each tank (initial weight of $30.1{\pm}0.2$ g) were fed one of the three EPs (EP1, EP2 and CEP) and one MP for 13 months. In field feeding experiment conducted in commercial flounder farm, survival, growth (30-600 g) and condition factor of fish fed experimental EP1 and EP2 were comparable to those of fish fed MP, but considerably higher feed efficiency and protein efficiency ratio were observed in fish fed experimental EPs. Viable cell counts from diet and water from MP diet were considerably higher than those from EP diet, and lysozyme activity from EP diet was higher than that from MP diet. GOT and GPT of fish fed the EP diet were considerably lower than those from MP group, but total protein and glucose concentration of fish fed the EP groups were not significantly different from that of fish fed the MP. Therefore, these results strongly suggest that EP diets could be developed to replace MP diet without adverse effects on growth performance and to enhance the immunity and protective ability of olive flounder against fish disease such as Vibro, Edwardsiella and Strptococcus.

Monocyte chemotactic protein-3 (MCP-3), a chemokine that is in a superfamily of structurally related small chemotactic cytokines involved in leukocyte trafficking, is regarded as a key factor in atherogenesis. In this study, we examined the changes in atherogenic parameters including hepatic lipid accumulation and oxidative balance in MCP- 3-overexpressing transgenic mice (MCP-3 mice) under atherogenic conditions. To induce an extreme atherogenic condition, mice were fed a high-fat, high-cholesterol (HFHC) diet for 12 weeks. The body weight and food intake were not changed by MCP-3 overexpression in the aorta. On a HFHC diet, the MCP-3 mice had higher plasma levels of total cholesterol and a higher atherogenic index compared with wild-type mice, although there were no differences in the plasma HDL-cholesterol and triglyceride levels. Furthermore, an increase in lipid accumulation was observed in the aortas as well as the livers of the HFHC diet-fed MCP-3 mice compared with wild-type mice. The activities of antioxidant enzymes increased in the livers of the HFHC diet-fed MCP-3 mice, whereas supplementation with antioxidants, naringin and hesperidin, reversed the activities of the hepatic antioxidant enzymes in HFHC diet-fed MCP-3 mice, indicating that there might be more oxidative damage to the tissues in the HFHC diet-fed MCP-3 mice leading to progression towards atherosclerosis and hepatic steatosis. Microarray analyses of the aorta revealed atherosclerosis-, PPARs-, lipoprotein receptor, and apolipoprotein-related genes that were affected by the HFHC diet in MCP-3 mice. These findings suggest that aortic MCP-3 overexpression may contribute to the development of atherosclerosis and hepatic steatosis under atherogenic conditions.

In present study possible hypolipidemic effects of garlic were investigated in an experimental model which consisted of 4 groups of Wistar rats(three weeks old): CO group received a basal diet(as a standard diet) contained 6.3% of corn oil. LO group was taken the experimental diet in which only 6.3% corn oil in basal diet was substituted by 12.6% of lard oil. So the experimental diet was somewhat high saturated fat diet. LG1 group was treated orally with garlic juice as 1% of raw garlic in the diet together with the same diet as the diet for LO group. LG2 group was taken 2% of garlic under the same dietary condition as that of LG1 group. The rat body weights prior and posterior to the experimental period were measured and the amount of the experimental dietary intake was determined at every 3 day interval. After the experimental dietary period of 30 days the blood obtained from all the sacrificed rats were analyzed for the biochemical parameters. Over the one month period of experiment there was no abnormality or apparent change in appearance and activity or diet consumption in all experimental rat groups. LO group fed a diet rich in lard showed significantly increased body weight gain rate by 30% and also elevated levels of triglyceride, total cholesterol and LDL cholesterol by 29.9%, 27.4% and 62.3% respectively and no significant difference in the levels of HDL cholesterol, GOT, GPT, blood glucose and blood urea nitrogen as compared to those of control group. So it seemed that the high calorie diet in LO group mainly contributed to the significant increase in body weight gain rate and other biochemical parameters. In spite of 1% garlic treatment LG1 group had significantly increased body weight gain rate by 25.2%, levels of triglyceride, total choesterol and LDL cholesterol by 25.2%, 24.6% and 50.5% respectively as compared to control and LO group, and no increase in the levels of HDL cholesterol, blood glucose and blood urea nitrogen. At garlic 1% diet there was no hypolipidemic efficacy in rat serum. Under the treatment with garlic 2% in diet LG2 group showed significantly increased body weight gain rate by 19.7% as compared to control and elevated levels of GOT, GPT and BUN by 85.8~96.4%, 127~148% and 88% respectively as compared to control, but LG2 group had significantly reduced levels of triglyceride, total cholesterol and LDL cholesterol as compared to LOand LG1 group. In present study there were no significant change in HDL cholesterol and blood glucose value. In LG2 group GOT, GPT and blood urea nitrogen values were slightly increased presumably due to the inhibiting effects of garlic on the hepatic or renal function of rats. Nevertheless in this study garlic may have some demonstrable hypolipidemic effects in rat.

곡식의 혼합비율은 백미에 보리쌀과 밀쌀을 각각 15%, 30%, 45%의 비례로 혼합하였고 비교군으로써 순백미군과 20% sugar casein diet를 두어서 총 8 group 으로 나누었다. 흰쥐 생후 $45{\pm}5$ 일(日) 된 albino rat로써 initial body weight 가 male이 $58{\pm}2\;g$, female이 $62{\pm}2\;g$ 이 되는 80 마리의 쥐를 8 군으로 하여서 한 군에(female 5, male 5)씩 나누어서 총 14주일 사육하였다. 성장율, 식이섭취량, F.E.R. P.E.R. 를 비교하여 보면 순백미 또는 백미에 보리를 혼합한 군보다 백미에 밀쌀을 섞은 군이 더 좋은 성장율과 F.E.R. 및 P.E.R. 을 나타내 주었다. 이와 같은 경향은 male군인 경우 female군보다 더 현저하나 nitrogen retention 에 역시 밀쌀 혼합군이 백미군이나 백미에 보리쌀을 혼합한 군보다 현저히 우수함을 볼 수 있으며 몸무게 증가와 밀접한 관계를 지니고 있음을 볼 수 있다. 곡류 diet 에서 배설된 nitrogen 중 $10{\sim}20%$가 변으로 배설되는 반면 표준군인 경우 nitrogen 이 거의 urine 으로 배설됨을 볼 수 있다. 이와 같은 결과는 곡류식인 경우는 함유된 단백질이 동물성 단백질식이에 비해 소화흡수되는 율이 저조하다. 혈청내 glucose 는 몸무게 증가와 밀접한 관계가 있었다. cholesterol 은 표준군이 곡류 diet 보다 total cholesterol 함량이 감소했으나 esterified cholesterol 과 free cholesterol 의 비에서 보면 곡류식이군이 표준군보다 높았다. 본 연구에서는 nitrogen 의 배설 상태 및 몸무게증가현상으로 미루어 밀쌀 혼합군이 보리쌀 혼합군보다는 우수하다는 결론을 지을 수 있다.

Cyclosporine A(CsA) is a widely used immunosuppressant for transplant patients and is also used for the treatment of a wide variety of systemic diseases with immunologic disorders. However, its use is frequently limited because of complications such as nephrotoxicity or gingival hyperplasia. Although several hypotheses have been postulated for CsA-induced gingival hyperplasia, i.e. various cytokine effects of inflammatory cells, existence of plaque or CsA itself, but its pathogenesis is still unclear. For experimental chronic CsA toxicity, salt depletion has been shown to increased susceptibility of rodents to the effects of CsA, and this maneuver facilitates production of arteriolopathy and interstitial fibrosis in kidney that mimic the changes found in human. The purpose of this study was to evaluate pathogenesis of CsA-induced gingival hyperplasia by comparing changes between CsA administration groups of normal standard diet and those of low salt diet group. Specific pathogen-free, 20 to 25 days old(120 to 150 g), male Fisher-344 rats(KIST, Korea), 120 to 150g of body weight, were assigned to four groups of six animals each after one week of adaptation period for powder food. Group 1 received olive oil($300{\mu}l/g\;of\;diet$) with normal standard diet(0.4% of sodium)(NSD). Group 2 received CsA(Cypol-N, Jonggundang, Korea; $300{\mu}g/g\;of\;diet$) with normal standard diet(NSD+CsA). Group 3 received same amount of olive oil with low salt diet(0.05 % of sodium, Teklad Premier, U.S.A.)(LSD). Group 4 received same dose of CsA with low salt diet(LSD+CsA). Rats were pair fed and were sacrificed after six weeks. Renal histologic lesions associated with CsA, consisted of cortical interstitial fibrosis, tubular atrophy and hyalinization of arterioles and the impairment of renal function including increase of serum creatinine and decrease of glomerular filtration rate was more severe in low salt diet group. These were proved as the results of activated of renin-angiotensin system in the kidney by low salt condition. Meanwhile the degree of gingival hyperplasia at incisor and molar tooth was less severe in low salt diet group compared with normal sodium diet group. Hyperplastic gingiva showed mild epithelial hyperplasia and expanded underlyng stroma which consisted of matrix increasement, capillary proliferation and dilatation. While the number and the activation of fibroblasts were increased, inflammatory cells were rare in the stroma. The immunohistochemistry for TGF-${\beta}_1$ in the kidney and gingiva revealed stronger positive in LSD+CsA in kidney but in gingiva of NSD+CsA. These results suggested followings; Gingival hyperplasia can be developed without inflammatory cells infiltration and seemed not induced by CsA by itself. The major role for gingival hyperplasia by CsA would be the secondary effect of TGF-${\beta}$, which maybe upregulated by CsA administration. Low salt diet can attenuate this hyperplasia perhaps by decreasing the activation of $TGF-{\beta}$.

As the elderly population has increased in recent years in Korea chronic degenerative diseases prevalent in the aged have garnered attention in relation to food behavior. In general, dietary intakes of elderly Koreans were inadequate in quality as well as in quantity. Especially, intakes of Ca, vitamin A, and riboflavin along with total energy were insufficient. They tended to consume high carbohydrate and low fat energy rates which may be resulted from long standing vegetable-based flood patterns. Relationships between dietary intakes and indices of cardiovascular diseases revealed that blood pressures and serum lipids patterns tended to be poor in individuals having high abdominal fat accumulations which seemed to be related with dietary consumption of high carbohydrate and insufficient intake of many nutrients. These results suggested that a nutritionally balanced diet including animal sources floods is needed in order to prevent an abdominal obesity and cardiovascular diseases. The bone health status of the Korean elderly appeared poor. It was more serious in women recording a higher prevalence rate of osteopenia and osteoporosis than in men. There were strong associations between dietary factors and bone health status. Bone mineral density was found to be higher with higher intakes of protein energy rate, the total amount of feeds, and many nutrients including Ca and p, indicating that a good quality diet is essential in maintaining healthy bone status in later life. mental health condition of the elderly as measured by cognitive function and the degree of depression was also inadequate and had strong association with dietary consumption. The positive results were obtained in individuals having an adequate dict. Therefore, it could be summarized that the physical as well as mental health in elderly Koreans are highly related with their dietary patterns. Thus, the older adults need te consume nutritionally well balanced diet in sufficient amount, which contains various flood items including significant amounts of animal source floods in a daily diet in order to maintain healthy condition.

This study was designed to evaluate the degree of the anxiety and discomfort experienced by first-time donors in platelet donation. The subject of this study was 309 first-time platelet donors visiting apheresis unit of St. Mary hospital in Seoul. The data was collected from Questionnaire during period of 28 April to 10 September 1999. The statistical methods used were t-test. ANOVA and stepwise multiple regression. The results were as follows. 1. The most common group were 21-30 years of age and soldier of job. 2. The mean scores of the platelet donor's anxiety was $1.60\pm0.32$. 3. The mean scores of platelet donor's discomfort was $1.72\pm0.44$. 4. The variables influencing anxiety were the physical condition. the level of education and donation experience. 5. The variables influencing discomfort were the job. diet before donation and physical condition. As the result above. the student group of the first time platelet donor experienced highest anxiety. It is important to assess the physical condition and diet before donation for more comfortable platelet donation. Furthermore. the developments of nursing interventions are required to reduce anxiety and discomfort of platelet donors.
