산림의 인산 영양진단에 적용했던 P-32 bioassay법을 영양특성이 다른 감귤나무에 직접 이용이 곤란하므로 궁천조생과 흥진조생 감귤나무를 공시 재료로 하여 사경과 토경재배 그리고 포장실험을 통해서 P-32 bioassay법과 관련된 기초 연구를 수행하였다. 1. 사경과 토경으로 재배된 2년생 감귤나무(궁천, 흥진조생)로 부터 뿌리를 채취하여 P-32 bioassay를 실시한 결과 인산 공급량과 인흡수능간에 고도의 지수적인 역상관을 보였다. 2. 한편, 야외포장실험의 경우 5월에는 인흡수능과 시비량간에 일정한 경향을 보이지 않았으나 7월과 9월에는 시비량이 증가함에 따라 인 흡수능은 감소하는 경향을 보였다. 이는 감귤나무가 인산에 대한 시비반응이 느리다는 사실을 암시한다. 또한, 인흡수능을 계절별로 봤을 때, 7월과 9월보다는 5월에 가장 컸으며 수령이나 표고보다는 토양의 비옥도에 의해 영향을 받고 있었다. 3. 인흡수능-유효인산-엽중인농도간의 상관을 비교할때 인흡수능-유효인산과 인흡수능-엽중인농도간의 상관이 유효인산-엽중인농도보다 컸음을 감안할때 P-32 bioassay법이 감귤의 인산영양진단에 효율적인 방법이 되리라고 생각한다. 4. P-32 bioassay를 실시하기 위해 채취된 뿌리는 저온보다는 실온에 저장하는것이 근활성을 유지하는데 효과적이었다. 5. 감귤나무의 근활성은 수관밑의 0∼5㎝ 표층에서 가장 높았으며 이는 다년간 표층시비에 기인되어 양분흡수에 관여하는 세근이 표층에 분포되었음을 시사하는 것이다. P-32 bioassay technique which were developed for determining forest tree's P-deficiency was introduced in order to provide an effective diagnosis method of phosphorus status in citrus tree. Some modification of the methods should be done because the physiological characteristics of forest trees and citrus trees are quite different, even though the basic principle is same. Thus, the fundamental steps needed to conduct the phosphorus diagnosis were investigated in the sand culture, pot culture and field experiment using two cultivars “Kung-Chun” and “Hung-Jin” of citrus trees. 1) The exponential relationships were obtained both in Kung-Chun and Hung-Jin from the sand culture experiment and the pot experiment. 2) No correlation between fertilizer levels and bioassay P-uptake was found from the field experiment in May, but in July and September there was a tendancy that highter fertilization reduced bioassay P-uptake, even though that was not statistically significant. Seasonal changes bioassay P-uptake were observed from all the fields. Soil fertility was more closely related with bioassay P-uptake than tree ages and plantation altitudes. 3) The degree of correlation of bioassaay P-uptake and soil available phosphorus or P-contents in leaves was higher than that of soil available phosphorus and P-contents in leaves, indicating that P-32 bioassay method is more sensitive than the conventional ones(soil and plant analyses) to make the P-status diagnosis. 4) The kept ar room temperature had higher P-32 absorption activity than those at 4℃ 5) The active fine roots were distributed mostly at the upper layer(0∼5㎝) of soil and around at the distance of canopy edge.

This study was designed to evaluate prevalence of allergen-specific antibodies in healthy adults. During Mar. ~ Aug. 2001, 1,925 subjects visited for medical check-up, were inquired to fill out a standardized questionnaire. Among them, 200 subjects who had no current and past allergic disorders were randomly selected for rhe current study and examined for allergen-specific antibodies using Korean inhalant panel of MAST-CLA allergen-specific IgE assay. Among them, 170 persons (85.0%) did not have any positive allergen-specific antibody. Each positive rate of 35 allergen specific antibodies was usually less than 3%, except Cockroach Mix (3.5%), Dermatophagoides farinae(8.5%), Dermatophagoides pteronyssinus(6.0%). Among 30 positive subjects, 19(63.3%) showed one or two allergen-specific antibodies. Although atopic subjects in non-allergic population were not common, few of them showed allergen-specific antibodies in Korean inhalant panel of MAST-CLA. Our results suggested that the standardized questionnaire and MAST-CLA could be an useful tool of a screening test for allergy, showing high specificity and sensitivity.

The main purpose of these studies were to clarify difference in Cheju-scoria and other solid media on growth and development of cherry tomatoes and on shift of component of the nutrient solution, seasonal change of content in tomato plant and to use practically Cheju-scoria as an excellent solid culture medium. The results obtained were summarized as follows; 1. Among scoria plots, the rares of dry weight, fruits and their sugar-acid ratio were higher in the plot was drained well with deep flow for one hour once a day. 2. Fresh fruits weights were lighter in rock wood and deep flow technique, but larger in scoria, Hyugashi (artificial gravel, Φ10∼12mm) and perlite in moving to higher flower cluster. 3. The results of analysis on macroelement among solution components showed decrease of concentrations of P and K in the period of growth and development. 4. Yeilds and brix of cherry tomato showed a tendency to increase in rock wool and Hyugashi than anothers. 5. The concentration of fertilizer base was increased in general solution culture. Transpiration and absorption were similar in Scoria plot and other media. 6. Nitrogen content in cherry tomato leaf showed a tendency to decrease at the latter half of the growth and development than the first half, and yet calcium and magnensium content were in the latter half. In the case of phosphorus and potassium showed no change the change in the growing period. 7. More studies of the Cheju-scoria development is required in order to use it as a soild medium for solution culture.

This study was performed to develop a standardized recipe for yuza pyun made of citron juice that is by-product of citron tea, to increase the utilization of citron. The effects of mungbean starch(15%, 18%) and dilution ratio of yuza extract(100%, 75%, 50%) on the quality characteristics were evaluated. The quality characteristics of the samples were estimated in terms of sweetness, color difference, texture profile analysis and sensory evaluation. Sweetness of the 18% mungbean groups were higher than 15% groups(p<0.001). The values of Hunter color system indicated that higher content of yuza extract tended to increase yellowness significantly(p<0.001). Texture profiles of hardness, adhesiveness, springiness, cohesiveness, gumminess of yuzapyun showed no significant differences among samples. For sensory evaluation, color and sourness were decreased as yuza extract was diluted, whereas elasticity and sweetness were increased. Yuza pyun containing 18% of mungbean starch with 50% diluted extract was the most preferred in overall acceptability. According to multiple regression analysis, color, sweetness, elasticity and sourness(in order) were important control factors in overall acceptability.

Cardiovascular disease is one of the most common cause of death in postmenopausal women. After the onset of menopause, the risk of cardiovascular disease is increased. Several risk factors of cardiovascular disease are well known to us. Among the risk factors, the changes of lipid profiles are roles for cardiovascular disease. Estrogen appears to protect the development of cardiovascular disease, by several mechanism. Especially the protective effect is believed to be mediated by the changes of lipid profiles. Decreased high-density lipoprotein (HDL)-cholesterol and increased low density lipoprotein (LDL)-cholesterol are important factors for development of cardiovascular disease. The purpose of this study was to evaluate the effect of hormone replacement therapy on the lipid profiles to include total cholesterol (TC), high density lipoprotein(HDL)-cholesterol, low density lipoprotein(LDL)-cholesterol, and triglycerides. We measured lipid profiles in 31 postmenopausal women and gave each conjugated equine estrogen (CEE, 0.625mg, day 1-30) plus medroxyprogesterone acetate (MPA, 5mg, day 1-12) for 12months. The levels of serum TC, LDL-cholesterol, and triglycerides were decreased significantly (p<0.05) and HDL-cholesterol was increased significantly (p<0.05) after 12months of hormone replacement therapy. These data suggest that hormone replacement therapy appears to protect agianst the development of cardiovascular disease by the changes of lipid profiles.
