초피를 유기용매 및 초임계이산화탄소와 보조용매로서 에탄올로 추출하여 각각의 추출수율을 측정하고, 이들 추출물들의 항균활성을 검색하였다. 유기용매별로 추출하여 각각의 추출수율을 측정한 결과, 증류수인 경우 20%로서 가장 높았고, 나머지 헥산, 에테르, 에탄올인 경우 3%이하로 매우 적었다. 또한 추출 용매로 초임계이산화탄소-에탄올을 병용했을 때 초피의 추출수율과 용해도는 초임계이산화탄소만을 사용했을 때보다 1.4배 이상 높았다. 용매별 추출물들의 항균성을 검색한 결과 모든 추출물들이 B.cereus에 대해 항균성을 나타내었는데, 특히 에탄올, 에테르 추출물들의 항균성이 더 큰 것으로 나타났다. 초임계이산화탄소-에탄올 추출물은 초임계이산화탄소만을 사용한 추출물과 거의 동일한 항균성을 나타내었다. Extraction yields of Zanthoxylum piperitum by organic solvents and supercritical carbon dioxide(SC-CO₂) with and without ethanol as a cosolvent, and antimicrobial activities of the extracts against Bacillus cereus were determined. Extraction yield by distilled water was the highest, 20%, while those by ethanol, ethyl ether and hexane were less than 3%. Extraction yield by SC-CO₂ with ethanol was 1.42 times greater than that by only SC-CO₂ Ethyl ether- and ethanol-extracts had potent antimicrobial activities against B.cereus. Extraction yield by SC-CO₂ with ethanol showed almost the same degree of microbial growth inhibition as that by only SC-CO₂.

Anchovy oil was extracted by supercritical CO_(2). and extraction yield and fatty acid composition were measured in the extract and residual fractions. EPA and DHA were 7.6~13.3% and 16.2~18.3% for the original anchovy oil. The extraction yield of anchovy oil increased as the extraction temperature decreased. Essentially no great differences were noticed in the fatty acid composition of the oil extracted under different extraction temperatures. Anchovy oil mixed with silver nitrate-coated silica gel was extracted by only SC-CO_(2)for 2 hr and by ethyl acetate-modified SC-CO_(2)for 2 hr at 60℃/276 bar. This produced higher extraction yield and higher concentration of EPA and DHA in the residual fraction. Starting with anchovy oil containing 13.3% EPA and 16.2% DHA. the residue fraction containing 23.9% EPA and 31.1% DHA was obtained.

고품질의 고도불포화지방산 제품을 제조할 목적으로, 멸치어유를 초임계 이산화탄소로 추출분획한 후 각 분획들의 추출수율과 지방산 조성을 측정하였다. 멸치어유의 주요 지방산은 palmitic acid. DHA, EPA, palmitoleic acid. myristic acid. oleic acid 였다. 멸치어유의 추출수율은 동일압력에서 추출시간의 증가에 따라 감소하였으며, 40과 50℃에서는 추출온도의 증가에 따라 감소하였으나, 60℃에서는 50℃ 보다 다소 높았다. 동일온도에서 C14와 C16 지방산들은 추출물 분획에 농축되었고, 나머지 지방산들은 추출 잔류물 분획에 농축되었다. EPA는 분획들간에 거의 일정한 경향을 보였으나, DHA는 추출잔류물 분획에 농축되었다. Silver nitrate를 silica gel에 코팅시킨 후 어유와 혼합하여 추출 2시간 동안은 초임계 이산화탄소로만으로 추출하고, 그 후 보조용매로 ethyl acetate를 첨가하여 2시간 동안 추출하였을 때 추출물 분획에서의 저급지방산인 C14:0은 추출잔류물에 비하여 5.0∼6.4배 농축되었고, C16:0은 1.9∼2.0배 농축된 반면, 추출잔류물 분획에서 EPA와 DHA는 23.9와 31.6%로 원료어유의 13.3과 16.2%에 비하여 1.8배와 1.9배 농축되었다. Anchovy oil was extracted by supercritical CO₂, and extraction yield and fatty acid composition were measured in the extract and residual fraction. EPA and DHA were 7.6∼13.3% and 16.2∼18.3% for the original anchovy oil. The extraction yield of anchovy oil increased as the extraction temperature decreased. Essentially no great differences were noticed in the fatty acid composition of the oil extracted under different extraction temperatures. Anchovy oil mixed with silver nitrate-coated silica gel was extracted by only SC-CO₂ for 2 hr and by ethyl acetate-modified SC-CO₂ for 2 hr at 60℃/276 bar.

Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

Bursaphelenchus xylophilus has been recognized as a causal pathogen of pine wilt disease (PWD). In order to identify relevant molecular biomarkers, we selected a variable region of endo-β-1,4-glucanase (β14-gcn) which was cloned from the cDNA of B. xylophilus and B. mucronatus. We then identified three novel β14-gcn isoforms: Bm-β14-gcn and Bm-β14-gcni from B. mucronatus, and Bx-β14-gcn from B. xylophilus. Bm-β14-gcn and Bx-β14-gcn were found to be identical, whereas Bm-β14-gcni was unique to B. mucronatus. These isoforms are Bursaphelenchus-specific and may be employed as molecular markers for the diagnosis of PWD. Our phylogenetic analysis showed that these β14-gcns from Bursaphelenchus species were associated most closely with fungal β14-gcns.

Cereal powder was processed using Jeju specialty grain and legumes such as milled upland glutinous rice, SoRiTae, JwiNunIKong and black sesame. Glutinous rice was soaked in water for 45 min at room temperature, steam-cooked for 10 min, dried for 45 min, roasted, and finally macerated without hull. SoRiTae and JwiNunIKong were roasted and macerated with hull without water-soaking and steam-cooking. The maceration of mixed grain and legumes for 10 min reduced the moisture content by less than 10%. Crude protein content was high in the untreated JwiNunIKong by 39.0%, and was increased slightly with steam-cooking and roasting. Crude ash content was decreased with maceration, and was high in macerated SoRiTae and JwiNunIKong with hull. The brightness was high in steam-cooked and roasted glutinous rice, and low in steam-cooked legumes. Water solubility index was high in steam-cooked glutinous rice, and decreased slightly in steam-cooked and roasted legumes. α-Degree was higher in the steam-cooked than the untreated, and was high in the order of JwiNunIKong, SoRiTae and glutinous rice. Sensory evaluation showed that the dispersion stability of cereal powder increased as the mixing ratio of glutinous rice decreased. Great preference on odor and overall acceptance were shown as the mixing ratio of glutinous rice decreased and that of legumes increased. Taste was correlated with the dispersion stability. The addition of sugar increased the solubility of powder and had no effect on dispersion stability.

Meige 증후군은 안검경련과 구-하악부의 근긴장이상을 특징적으로 보이는 신경학적 임상증후군이다. 발병원인은 아직 불분명하나 아세틸콜린과 도파민의 신경활성과다(excess neuronal activity)가 원인으로 여겨지고 있으며, 치료로는 향도파민성약물과 항콜린성약물, 그리고 보튤리듐독소 주사가 이용되고 있다. 그러나 증상양상이 다양하며 심리적 영향을 받으므로 전환장애 혹은 불안장애 등의 정신과적 문제로 오진되는 경우가 있다. 저자들은 49세 여자로 초기에 전환장애로 진단되었으나 Meige 증후군임이 밝혀져 성공적으로 치료되었던 환자 1례를 경험하여 문헌고찰과 함께 보고한다. A Meige's syndrome is a rare neurological syndrome characterized by blepharospam and oro-mandibular dystonia. Its pathophysiology is not clearly determined yet, but the hypothesis of dopaminergic and cholinergic hyperactivity is most widely accepted. Anticholinergic drugs, antidopaminergic drugs and botulism toxin injection are currently used for the treatment of Meige's syndrome. The Meige's syndrome could be misdiagnosed as a psychiatric disorder such as conversion disorder or anxiety disorder, because clinical features of the Meige's syndrome are very variable and affected by psychological factors. The authors experienced one case of a 49-year-old female patient who was initially misdiagnosed as conversion disorder but confirmed later as Meige's syndrome, and then successfully treated.

Microencapsulation of anchovy oil with different wall materials such as sodium alginate. chitosan and β-cyclodextrin was investigated. Microencapsulation was accomplished by ejecting an oil/water emulsion into a dispersion fluid under high pressure through an orifice. As a dispersion fluid, 0.2% calcium lactate was appropriate for sodium alginate, while 0.18 sodium hydroxide for chitosan in terms of capsule size and distribution, and emulsion stability. β -cyclodextrin formed inclusion complex with anchovy oil. The microcapsules were stored at 22 and 30℃ for 8 days, and their stability was tested. The acid value remained unchanged and the peroxide value was not detected.
