As the seriousness of hypertension in adults is increasingly recognized, attention is being focussed on its control through continuous health supervisions. Complications arising from high blood pressure exceed those of many other adult health problems and affect the nursing needs of these patients. In order to contribute to effective nursing care planning and improved health supervision, 248 medical records of hypertensive patients admitted to Internal Medicine at Ewha Medical Center from January 1971 to August 1976 were examined. Results were as fellows: 1. The sample group averaged 5.0% of the total number of patients admitted to internal medicine during the period studied. The proportion increased slightly with each successive year. 2. Patients with hypertension averaged 31.4% of all patients with cardiovascular discease. This proportion was stable over the period. 3. Hypertensive patients were primarily in their 40s. The average age was 55.1 years. 4. Women were most frequently affected in their 60s and men in their 40s. 5. The bloo pressure of these in their 30s was not well controlled on discharge. Rates for those in their 30s averaged 151.5/107mmhg, for those in their 40s 161.5/110mphg, and for those in their 60s 169/100mmhg. 6. Complications increased with each age range from the 40s to the 60s for both men and women. 7. Complications related to systolic hypertension occurred most frequently when the rate exceeded 200mmhg. Cerebral vascular accident was the primary complication, presenting implications for nursing intervention. 8. Complications related to diastolic hypertension occurred most frequently when the rate was in the $110{\sim}129mmhg$ range. C.V.A. again was the primary complication needing nursing care planning. 9. Diets ordered for patients were low salt 79.%, salt free 4.19%, diabetic 6.1%, and protein free ('no protein') 2.0%. Caloric, salt end protein levels were not defined. Recommendations based on the findings were directed to diet and other therapies.

This is an analysis of the dietary behavior, nutrient intake status and INQ(Index of nutritional quality) of 129 college women according to their residences in the Daegu area. The average height and weight were 160.0 cm and 54.5 kg respectively. Diet intake data were obtained by using the 24-hour recall method to evaluate the usual diet of the subjects. The energy intake of the group, living alone was higher than that of living a roommate and living at home. Ca, Fe, Zn and folate intakes were low in all the groups. The composition rate of carbohydrate, protein and fat for energy intake was 58.9 : 15.5 : 25.6 in living alone, 59.9 : 15.1 : 25.0 in living with a roommate and 61.2 : 15.5 : 23.3 in living at home, compared with the preferred of 65 : 15 : 20. The group living alone showed significantly better mean adequacy ratio(MAR, 0.7) than the other groups (p<0.05). The group living with a roommate showed significantly better INQ in vitamin $B_6$ (p<0.01) and Fe (p<0.05) than the other groups did In conclusion, this study indicates that nutrient intake in college women in Daegu is considerably lower than the RDA values. Furthermore the group living alone showed better dietary behavior and nutrient intake status than the other groups. A nutrition education program for college women is necessary.

Eight male cattle of the Local Yellow breed with an average live weight of 121 kg and an average age of 18 months were used to evaluate the effects of different levels of sun-dried cassava (Manihot esculenta) foliage supplementation on mineral metabolism in growing cattle fed rice straw and para grass as basal diet. Rice straw ad libitum and para grass (Brachiaria mutica) at 1% DM of BW comprised the basal diet. The study was arranged as a $4{\times}4$ double Latin square design, with cassava foliage contributing 0, 0.8, 1.6 or 2.4 g CP/kg BW. The cassava foliage intake was lower than the planned levels. DM consumption was significantly affected by cassava foliage supplementation, with the largest intake observed at the two highest levels of cassava foliage supplementation. Rice straw intake showed the opposite pattern, with lower intake at higher cassava foliage supplementation. No refusals occurred for para grass in any of the treatments. Ca, P, Mg, K, S and Mn intake increased significantly with increasing intake of cassava foliage, but Na intake was not affected by treatment. Faecal excretion of Ca, Mg, S and Mn increased significantly with increasing cassava foliage intake. There were no differences between P, K and Na excretion in faeces. There was a significant diet effect on Mg, S and Mn digestibility. Mg and Mn digestibility increased with increasing cassava foliage supplementation, while S digestibility decreased. Ca, P, K and Na digestibility was not affected by diet. There was a significant effect of treatment on P retention, with the highest value observed for supplementation with 1.6 g CP/kg BW cassava foliage. Ca and Mg showed similar trends, with the highest retention again for supplementation with 1.6 g CP/kg BW cassava foliage. There were weak but significant positive correlations between nitrogen retention and the macro minerals Ca, P and Mg. Furthermore, retention of all these minerals was positively correlated. Mineral losses in urine were not affected by dietary treatment with the exception of P excretion, which was affected by treatment. In conclusion, cassava foliage is a good Ca source which compensates for the low Ca content in rice straw and para grass, but P deficiency appears to be exaggerated in cattle with higher cassava intake. The results suggest that under these conditions growing cattle on a high cassava intake would benefit from P and S supplementation.

This study was conducted to evaluate the dietary supplementation of citrus byproduct (CBP) on the growth performance, feed utilization, and innate immune responses of juvenile olive flounder Paralichthys olivaceus under low water temperatures (11-15℃). Dietary L-ascorbyl-2-polyphosphate was replaced with graded CBP levels at 0 (Con), 25 (CBP25), 50 (CBP50), 75 (CBP75), and 100% (CBP100). Triplicate groups of juvenile olive flounder were handfed with one of the diets twice a day for 42 days. The growth performance and feed utilization of fish fed with diet containing levels of CBP75 or CBP100 increased significantly compared to those of fish with fed Con. Dietary CBP supplementation increased the protein efficiency ratio in fish. There was no significant differences in innate immune responses between groups, even though CBP supplementation tended to increase. These findings indicate that CBP could be used as a vitamin C source and improve the growth performance of juvenile olive flounder under low water temperatures.

On a urea-molasses-straw (3:15:82; UMS) based diet effect of graded levels of cottonseed cake (CSC) supplementation on the performance of native (Bos indicus) bulls has been studied for 167 days. Eighteen growing bulls of $129{\pm}13.4kg$ weight and about 14 months old were randomly allocated to three dietary treatments designed in a completely randomized design, having six animals in each treatment. Three dietary treatments were 0, 0.5 and 1.0 kg CSC per head/d. In addition, each animal also received ad lib. UMS, 4 kg Napier (Pennisetum purpureum) grass, 500 g of each of rice and wheat bran and 60 g mineral mix daily. For unit increase in CSC, total DM intake was increased by $1g/kg\;W^{0.75}/d$ but the straw DM intake decreased by $0.54g/kg\;W^{0.75}/d$. Whole gut digestibility of DM and OM was not effected but N and ADF digestibility increased with incremental increase in dietary CSC. For unit (1kg) increase in dietary CSC intake N and ADF digestibility increased by 10 (${\pm}1.155$) and 3 (${\pm}1.732$) unit respectively. Microbial N yield for the 0, 0.5 and 1.0 kg CSC were 5.63, 5.28 and 5.16 g/kg OM apparently fermented in the rumen respectively. For each gram increase in CSC, N intake and N balance increased by 0.626 (${\pm}0.015$) and 0.625 (${\pm}0.0814$) mg/kg $W^{0.75}/d$. High apparent N balance was contrasted with low live weight gain, e.g., for 1 kg increase in CSC supplementation, live weight gain increased by only 0.077 (${\pm}0.00288$) kg/d ($r^{2}=0.99$; p<0.01). The conversion efficiency was 12.98 kg CSC per kg of live weight gain. It was concluded that unless the protein is being protected from the rumen degradation, addition of CSC to UMS diet would have little nutritional or economic advantages.

As a one of unsaturated fatty acid, polyunsaturated fatty acids (PUFAs) have multiple actions: as precursor of prostaglandins (PGs), steroid hormone synthesis and energy production in animal reproduction. PUFAs, which include omega-3 (n-3) and omega-6 (n-6), are derived from the diet and changed by diet, species, breed and season. The plasma membrane of spermatozoa in mammals contain various PUFAs. These composition of PUFAs regulate the membrane fluidity and cause lipid peroxidation via generation of reactive oxygen species (ROS). Induced lipid peroxidation by ROS decreased viability and motility of spermatozoa, and it is reduced by addition of antioxidant and low concentration of PUFAs. Because oocytes of animal have a high lipid components, process of oocyte maturation and embryo development are influenced by PUFAs. In in vitro study, oocyte maturation, embryo development, intracellular cAMP and MAPK activity were increased by treatment of n-3 ${\alpha}$-linolenic acid (ALA) during maturation, whereas n-6 linoleic acid (LA) negatively influenced. Also, inhibition of fatty acid metabolism in oocyte influenced blastocyst formation of cattle. PGs are synthesized from PUFAs and various PUFAs influence PGs via regulation of PG-endoperoxide synthase (PTGS). Steroid hormone synthesis from cholesterol is regulated by expression of steroid acute regulator (StAR) protein and mRNA. Exogenous n-3 and n-6 PUFAs altered sex hormone in animal through stimulate or inhibit StAR activity. Because PUFAs altered PG and steroid hormone synthesis, follicular development was influenced by PUFAs. This effect of unsaturated fatty acid could provide information for improvement of reproductive ability in animals.

Objectives : Phyllostachys pubescens and Scutellaria baicalensis are considered to be effective in promoting blood circulation in traditional medicine. In this study, we examined whether a mixture of P. pubescens leaves and S. baicalensis root (BS21) had any anti-obesity, anti-hyperlipidemia, or anti-hyperuricemia effects and the possible mechanisms of action. Methods : We examined the effects of BS21 in high-fat diet (HFD)-induced obese mice. Mice were fed HFD with BS21 (75, 150, or 300 mg/kg) or Garcinia cambogia extracts (245 mg/kg) as a positive control for 8 weeks. At the end of 8 weeks, body weight, liver and adipose weight, adipocyte size, plasma lipid profiles, adipokine and uric acid levels, and adipose tissue expression levels in obesity and uric acid production-related genes were examined. Results : BS21 decreased body weight gain, white adipose tissue, liver weight, adipocyte size, and liver triglyceride accumulation. It also reduced levels of plasma glucose, triglycerides, non-esterified fatty acids, total cholesterol, low-density lipoprotein cholesterol, alanine transaminase, leptin, and uric acid. In contrast, BS21 increased adiponectin levels. Furthermore, BS21 decreased the expression levels of adipogenesis-related genes, such as peroxisome proliferator-activated receptor γ, sterol regulatory element binding protein-1c, and fatty acid synthase, as well as xanthine oxidoreductase, which is involved in uric acid production. Conclusions : These results suggest that BS21 may exert anti-obesity, anti-hyperlipidemia, and anti-hyperuricemia effects in HFD-induced obese mice by regulating the expression of xanthine oxidoreductase and adipogenesis-related genes.

In balance experiments with rats either 25 or 50% of the casein protein in the control diet was replaced with one of the following eight sun-dried tropical biomass products: water spinach plants (WS) (Ipomoea aquatica Forsk), leucaena leaves (LL) (Leuceana leucocephala), duckweed plants (DW) (Lemma minor L.), groundnut foliage (OF) (Arachis hypogaea L.), trichantera leaves (Tric) (Trichantera gigantea), indicago leaves (Ind) (Indigofera hirsuta), mungbean foliage (Mb) (Phaseolus aureus), and cassava leaves (CL) (Manihot esculenta Crantz). The experiment included 102 rats with six individuals per treatment group. In three of the 16 biomass treatment groups, feed intake and weight gain of the rats were unacceptably low, and therefore they were excluded from the statistical evaluation, The crude protein (CP) content of the biomass products varied between 20.9% (Tric) and 33.2% (DW), whereas the content of NDF varied between 18.5% (Ind) and 32.2% (DW) of dry matter (DM). The total content of essential amino acids (g/16 g N) was comparable with that of alfalfa meal, except for GF and Tric, which were inferior. Between plant species, differences in dietary digestibility of organic matter (dOM) and CP (dCP) were observed (p<0.001). Also, the replacement level negatively influenced dOM and dCP (p<0.001). The lowest values for dOM (p<0.001) were observed for diets including biomass products with the highest content of NDF (OF, Tric, Mb, LL). Digestibility of CP was negatively affected by level of protein replacement. Significant (p<0.001) differences were found in N-retention and biological value among diets with different biomass products. The most favourable overall results were obtained for DW, WS and CL. The main factors affecting the nutritive value of the diets tested were their NDF content, dCP and AA profile of the biomass. Also antinutritive component(s) may have influenced the process of digestion and metabolism of some of the biomass products.

DE와 GE의 급여가 어린 병아리의 골격발달에 미치는 영향을 알아보기 위해 1일령된 Hy-Line Brown 수평아리 4처리$\times$4반복$\times$5수/반복 100마리에게 3주간 대조군으로 IF 함량이 매우 낮은 SPC를 급여했다. 실험군은 DE와 GE를 1. 0, 2.0mM 두 수준으로 첨가 급여하였다. 이때 사료의 Ca 수준은 골격발달에 좀더 민감한 반응을 나타낼 수 있도록 요구량의 50% 수준으로 했으며, Phosphate는 정상수준으로 급여하였다. 식이섭취량과 체중증가량은 군간에 차이를 보이지 않았고, ALP activity는 GE군과 대조군에 비해 DE군에서 유의하게 감소하였으나(p〈0.05) 첨가수준간에는 차이가 없었다. 경골의 회분 %는 대조군에 비해 DE, GE군에서 유의하게 증가하였으나(P〈0.05), 두 IF간 및 첨가수준 간에는 차이가 없었다. 경골의 파괴강도는 모든 처리군에서 유의차를 보이지 않았다. 즉 DE의 급여가 GE에 비해 ALP를 유의적으로 감소시켰지만, 경골의 회분 %와 경골 파괴강도에 있어서는 DE와 GE군 간에 급여수준에 따른 차이를 보이지 않아 이에 대한 연구가 더 필요할 것으로 사료된다.

세계적으로 축산 폐수로 인한 환경오염 문제는 매우 심각하게 거론되어져 왔으며 특히 네덜란드, 덴마크, 영국 등과 같은 축산 선진 국가에서의 연구는 매우 심도 있게 이루어져 왔다. 우리 나라의 경우도 최근 들어 축산업이 대규모 전업화 혹은 기업화 되면서 가축이 배설하는 분뇨가 심각한 수질 및 토양 오염원이 됨에 따라, 정부는 이들 축산 폐수를 억제하기 위한 일환으로 환경 시행법을 법률화하고 있다. 또한 농림수산부는 시설 개선과 축산 폐수의 처리를 위한 시설 지원에 많은 노력을 기울이고 있다. 특히 환경청이나 환경 관련 단체의 활동이 강화되면서 일반 국민의 수질오염에 대한 관심이 고조되고 있는 가운데 이에 부응하는 축산인들의 자체 노력이 가세하여 축산 폐기물로부터 발생하는 수질오염에 대한 경각심은 초미의 관심사로 대두되고 있다. 동물의 품종의 개량과 함께 생산성을 저해하는 각종 질병의 예방, 치료 약제, 성장 촉진 및 사료 효율을 개선할 수 있는 물질이 사료첨가제로 개발되어 사용되었다. 동물의 성장 능력을 향상시키고 사료 효율을 개선하기 위하여 사용되는 물질로서는 항생제(Thrasher, 1968), 효소제(권 등, 2003), 호르몬제(Chung, 1990) 등이 있으며, 최근에는 축산악취저감 및 사료 효율개선 등을 위한 생균제에 관한 연구(박 등, 2001; 길 등, 2004)가 진행되고 있다. 하지만, 양돈 산업에 있어 생산성 향상뿐만 아니라 환경 친화적인 축산을 위하여 양돈을 하면서 발생하는 오염 물질을 감소시키는 것이 가장 시급한 문제로 대두됨에 따라 질소의 배설량을 줄이기 위해서는 저단백질 사료를 급여하거나 단백질 소화율을 개선시킬 수 있는 소화효소제나 미생물제제, 효모제, 생균제 등을 이용하여 배설량 및 질소의 배출량을 감소시킨다는 연구들이 있었으며(민 등, 1992; Park 등, 1994), Sutton 등(1999)과 Shriver 등(2003)은 사료내 단백질 수준을 낮추고, 합성아미노산을 급여함으로써 질소 배설량을 감소시켰다고 보고하였다. 따라서 본 연구에서 친환경적인 사료 개발은 사료 효율 및 영양소 소화율의 개선, 분뇨내 질소 배출량 및 악취 발생량을 감소시킬 수 있는 저공해 사료 개발에 대하여 연구하고자 하였다. 저공해 사료 개발에 대한 시험에서는 육성돈의 사료에서 대사에너지 함량을 낮추고, α-1, 6-galactosidase와 β-1,4-mannanase를 포함한 복합 효소제를 첨가하여 성장 능력 및 소화율에 미치는 영향을 알아보고자 시험을 실시하였다. 사료내 낮은 CP의 함량과 복합 생균제를 첨가 급여 성장능력, 질소배설량 및 악취발생량에 미치는 영향을 조사하기 위하여 실시하였다.
