중력분을 이용하여 제면한 후 가압가열, microwave 및 가압가열과 microwave 병행 처리한 후, 생면 및 삶은 면의 품질에 미치는 영향에 대하여 알아보았다. 생면의 pH는 microwave 1 min 처리구에서 무처리구와 유의적인 차이를 보이지 않았으며, 수분 함량은 autoclave 50 min 처리구에서 무처리구와 유의적인 차이를 보이지 않았고, 그 외의 처리구에서는 모두 수분 함량이 감소함을 확인하였다. 면의 색도 측정 결과는 명도는 무처리구에 비해 모든 처리구에서 감소하였으며, 적색도는 microwave 1 min 처리구는 감소한 반면, 나머지 처리구는 증가하였다. 황색도는 autoclave 50 min 처리구와 autoclave 50 min/microwave 1 min 병행 처리구에서 증가한 반면, 나머지 물리적 처리구에서는 감소하였다. 삶은 면의 색도에서는 명도, 적색도, 황색도 모두에서 무처리구에 비하여 물리적 처리구에서 증가한 값을 나타내었다. 물성 측정 결과는 경도, 부착성, 응집성, 검성, 복원성에서 무처리구와 비교시 microwave 1 min 처리구는 유의적으로 감소하였으며, 그 외 처리구에서는 유의적으로 증가한 값을 나타내었다. 탄력성과 전단력은 모든 처리구에서 유의적으로 증가하였으며, 인장력은 가압가열 30 min 처리구와 무처리구가 유의적인 차이를 보이지 않았으나, 나머지 물리적 처리구에서는 유의적으로 증가하였다. 관능 평가 결과는 생면의 경우 색 항목에서 물리적 처리구들이 유의적으로 낮은 점수를 받았다. 맛, 질감, 향 항목에서는 무처리구와 물리적 처리구간 유의적 차이를 보이지 않았다. 전체적인 기호도에서는 microwave 1 min 처리구가 가장 높은 점수를 얻었으며, 가압가열(50 min)과 microwave(1 min) 병행 처리구는 무처리구와 비슷한 점수를 얻었다. 따라서 제면 후 가압가열 및 microwave 처리가 생면 및 삶은 면에 있어서 색과 질감 항목을 보완, 개선시킨다면 알러겐성이 저감화된 면을 제품화하는데 적합할 것으로 사료되어진다. This study was conducted to determine the effects of physical treatments for quality of wet noodles. Noodles were being tried with a microwave (for 1 min), an autoclave (for 30 or 50 min), and both autoclave and microwave (for 30/1 min or 50/1 min). The results showed that the pH levels were slightly decreased after treatments of autoclave and autoclave/microwave. The moisture contents were considerably decreased as compared to the control except autoclave (50 min). After all treatments, the lightness was decreased in all samples, but, redness was increased (except microwave) and the yellowness was increased after autoclave (50 min) and autoclave/microwave (50/1 min). Texture was increased as compared to the control except microwave. In the sensory evaluation, the noodles treated with microwave, autoclave (50 min), and autoclave/ microwave (50/1 min) showed a high score in overall preference. From these results, both the autoclave and microwave methods can be applied to the wet noodles without diminishing its quality to a great extent.

본 연구에서는 가압가열 및 microwave 처리가 gliadin의 항원성에 미치는 영향을 살펴보기 위해 강력분에 가압가열과 microwave를 단독 또는 병행으로 처리하여 Ci-ELISA, SDS-PAGE 및 immunoblotting을 실시하였다. 가압가열 처리의 경우 시간이 길어질수록 IgG와의 결합력이 감소하였으며, 특히 50분 처리구에서 약 87%로 가장 낮은 결합력을 보였다. 또한 SDS-PAGE와 immunoblotting 결과에서도 무처리구에서 강하게 보였던 gliadin band가 가압가열처리에 의해 거의 소실되고 항체와 반응하지 않았다. 가압가열 및 microwave를 병행 처리 시도 마찬가지로 gliadin의 결합력이 감소하였으며, 처리구 중 가압가열 50분, microwave 5분 처리구에서 약 93%로 가장 낮은 결합력을 보였다. 반면 microwave를 단독으로 처리한 경우에는 일부 단백질의 변화는 관찰되었으나, 항원성 감소에는 효과가 없음을 확인하여 단백질 변화가 항원성에는 큰 효과를 준 것 같지 않다. 이상의 결과를 통해 가압가열 단독 처리 및 가압가열 및 microwave의 병행처리 시 gliadin의 항원성이 감소함을 확인하였다. This study was conducted to evaluate the effects of physical treatments on the antigenicity of gliadin in strong wheat flour. Strong wheat flour was treated with an autoclave (5, 10, 30, 50 min), a microwave (1, 5, 10 min), or both (10, 30, 50 min/ 5, 10 min), followed by SDS-PAGE, immunoblotting, and Ci-ELISA using anti-gliadin IgG. The results indicated that the binding ability of IgG to gliadin in strong wheat flour slightly decreased after autoclaving or autoclaving/microwaving. In particular, the binding ability was reduced to about 87% after autoclaving for 50 min and to 89% after autoclaving/microwaving (50/5 min). In addition, gliadin bands in the 50 min autoclaved group disappeared in both SDS-PAGE and immunoblotting. On the other hand, the antigenicity of gliadin was unaffected by microwaving alone. In conclusion, the results of this study suggest that autoclaving may reduce the antigenicity of gliadin in strong wheat flour.

Objective : This study was to examine the low frequency EA is associated with NMDAR and phosphorylation of NMDAR NR-2B subunits in the spinal cordMethods : We investigated that only those rats without overt signs of spinal cord or root damage such as paralysis or lameness were used for experimentation. The NMDA antagonist, D-2-amino-5-phosphonopentanoic acid dissolved in sterile saline and injected intrathecally. Two stainless-steel needles were inserted in each hind leg at those acupoints corresponding to Zusanli(S36) and Sanyinjiao(Sp6) in man and wereconnected to an electric stimulator The EA wit 2 ㎐ stimulation started immediately after AP-5 injection for 30 min. Results : EA analgesia was slightly reduced by intrathecal injection of NMDAR antagonist AP-5, but analgesic effects of EA still showed at 60 minutes after termination of stimulation in all EA-treated group. In the Western blot analysis, the levels of NMDAR NR-2B and phospho-NR-2B were slightly induced by EA stimulation in the spinal cord. These expressions were significantly inhibited by spinal blockage of AP-5. As for regional reaction of NMDAR NR-2B and phospho-NR-2B, immunoreactions were observed throughout all laminae of the dorsal horn of spinal cord and weaker ones showed in the neck region. The mean IOD of phospho-NR-2B in the superficial laminae and nucleus proprius of EA-treated rats were significantly increased compared with normal ones, these expressions were decreased in EA-treated with AP-5 groupsConclusion : It is concluded that EA stimulation may be involved NMDAR activation through phosphorylation of spinal NMDAR NR-2B subunit. 목적 : 저주파에 해당하는 2 Hz 전침 자극이 척수 N-methyl-D-aspartate receptor (NMDAR)의 NR-2B subunit의 발현 및 인산화에 미치는 영향을 조사하였다. 방법 : Sprague-Dawley계 흰쥐를 Størkson 등의 방법에 의해 척수막의 지주막하강에 catheter를 삽입하는 수술을 행한 후 마비 등의 척수 손상을 나타내지 않는 개체를 대상으로 하였다. N-methyl-D-aspartate (NMDA) antagonist인 D-2-amino-5- phosphonopentanoic acid (AP-5)를 투여한 후 족삼리와 삼음교에 해당하는 부위에 30분간 전침 자극하였다. 무통각 여부는 hot plate test를 시행하였으며 NMDAR NR-2 subunit 발현과 인산화 여부는 Western blot과 면역조직화학적으로 살펴보았다. 결과 : 전침 무통각은 전침 자극 후 180분 후까지 지속되었으며 NMDA antagonist인 AP-5를 투여하였을 때 전침 무통각이 저하되었으나 유의성은 나타내지 않았다. Western blot 분석으로 보아 NMDAR NR-2B 및 인산화 NR-2B의 발현은 전침자극에 의해 미약한 증가를 보이나 AP-5투여에 의해 현저한 저해를 보였다. 면역조직화학에 의한 척수배각 구역별 발현을 보면 NMDAR NR-2B 및 인산화 NR-2B는 전 배각에 걸쳐 관찰되나 경부 (층판 Ⅴ-Ⅵ)에서 약한 반응을 보였다. 전침 자극에 의한 각 군별 NR-2B 발현은 유의한 차이를 보여 주지 않았으나 인산화 NR-2B는 천층 (층판 Ⅰ-Ⅱ)및 고유핵 (층판 Ⅲ-Ⅳ)에서 유의성 있는 증가를 보였다. 전침 자극시 AP-5 투여는 유의성은 보이지 않았으나 인산화 NR-2B발현을 저해하였다. 결론 : 저주파 2 Hz 전침에 의한 무통각은 NMDA antagonist인 AP-5 투여에 의해 저해될 뿐아니라 NMDAR NR-2B subunit의 인산화를 저해하는 것으로 보아 전침 무통각의 과정에 NMDAR 및 NMDAR NR-2B의 인산화가 관여함을 알 수 있다.

안재철,안진봉,정민수,강병희 동아대학교 건설기술연구소 2000 硏究報告 Vol.24 No.2

This study is to investigate economical efficiency of using ALWOOD Form compared with that of EURO Form. ALWOOD Form is improved in the capacity in the wall-concrete structure in stead of using the existing form which has problems such as, the loss of labor when it is constructed or disjointed, and it's economical efficiency compared with that of EURO Form. The price of ALWOOD Form is more expensive than that of EURO Form due to its main material, aluminum-compound metal, composing frames. In a consequence, the cost of materials per unit area is increased. However, labor cost of ALWOOD Form based on the result of mobilization of manpower in construction field is saved due to the reduction of labor in using ALWOOD Form compared with that of EURO Form. As a result, using ALWOOD Form is more economical than that of EURO Form because saving labor cost which plays a major part in cost saving in formwork is more effective in retrenching total cost than increment of material cost.

Schwann cells(SCs), an important component of the peripheral nervous system, intract with nerous to mutually support growth and replication for the peripheral nerve regentation. Recently, ading SCs to the lumen of guidance channel is widely tried to improve regeneration or to make regeneration possible over otherwise irreparable gaps. however, it is not easy to isolate and multiplicate SCs as much as enough to help the axonal regeneration. For the allogeneic SCs source for tubular nerve guidance, we developed a little bit improved technique of harvesting and multiplicating SCs. by culturing dispersed dorsal root ganglia in specially designed medium with growth factors and serial processing, we repeatedlly generate relatively homogenous SC cultures. Our technique was compared with other methods of literature using immunostaining methods such as GFAP, S100, BDNF and the total SC count assessment at different time interval after primary culture.
