To evaluate usefulness of application of MAST-CLA to indetify allergens, authors conducted MAST-CLA allergen-specific IgE assay and collected allergy related symptoms in 118 allergic patients diagnosed at Soonchunhyang University Chunan Hospital during October 1998 through January 2000. The results were as followings; 1. The mean (SD) age was 23.1 (±12.17) years old and teenagers accounted for 33.1% of patients. 2. The frequent allergic symptoms were sneezing (59.3%), rhinorrhea (53.4%), nasal stiffness (44.1%), itching sensation (24.6%), cough or sputum (16.1%), and eye symptom (8.5%) in order. 3. Among these subjects, 62.7% of patients revealed at least more than one specific allergen and 70.3% showed elevated total IgE levels by MAST-CLA. The three most frequent specific allergens were Dermatophagoides farinae (47.5%), Dermatophagoides pteronyssinus (45.8%), and house dust (30.5%). 4. While age was not significantly related to positive of both specific allergens and total IgE (P>0.05), sneezing and nasal stiffness were significantly associated with positive of specific allergen and total IgE, respectively (both P<0.05). 5. Total IgE increased with the number of specific allergens, but both specific allergen and total IgE were not significantly related to increases of allergic symptoms (P>0.05). In conclusion, our data suggest that MAST-CLA allergen-specific IgE assay is useful measure for identification of causative allergens in allergic patients, however, it is recommended that more specific allergic antigens should be determined and replaced or added to Korean inhalent panel of MAST-CLA.

청국장의 구수한 맛과 생리적 기능성을 증대시키기 위한 적정발효기간을 설정하기 위하여 이 연구를 수행하였다. 전체 Isoflavone의 함량은 24시간 발효하였을 때 5.847%로서 가장 높게 나타난 반면, 48시간 발효하였을 때 1.178%로서 가장 낮게 나타났다. 전체 유리아미노산의 함량은 24, 48, 72시간 발효하였을 때에 각각 3.414, 20.678, 27.411%로서 발효기간이 길어질수록 증가하였으나, 96시간 발효하였을 때에는 22.891%로서 오히려 감소하였다. 또한 고혈압의 예방효과가 있는 것으로 알려진 γ-amino butyric acid(GABA)를 비롯한 27종의 유리아미노산이 72시간 발효하였을 때에 가장 많이 생성되었으며, 24시간 발효하였을 때에는 ethanolamine만이, 48시간 발효하였을 때에는 asparagine을 비롯한 3종, 96시간 발효하였을 때에는 taurine을 비롯한 5종의 아미노산이 가장 많이 생성되었다.(이 논문은 2005년도 기성회 연구비 지원에 의하여 연구되었음) This research was performed to investigate optimum fermentation period for the better taste and physiological function of chungkukjang. Total isoflavone content was the highest at 24 hours of 5.847%, but it was the lowest of 1.178% at 48hours of fermentation period. When fermented for 24, 48, and 72 hours, total free amino acid(FAA) contents were increased by 3.414, 20.686, and 27.411%, respectively. But it was decreased as 22.891% at 96 hours of fermentation period. Twenty seven free amino acids, including the γ-amino butyric acid(GABA), which is well known for its effect against hypertension, produced the highest amount of its contents at 72 hours of fermentation period. When fermented for 24 hours, only ethanolamine produced the highest amount of its content, while three free amino acids including asparagine produced the most amount at 48 hours. And 5 free amino acids including taurine produced the highest amount when fermented for 96 hours.

방사능 동위원소(P-32)를 이용한 감귤나무의 인산 영양 진단법의 개발

현해남,송성준,한해룡,유장걸,김형옥 제주대학교 방사능이용연구소 1989 연구보고 Vol.4 No.-

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.
