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 di-(2-ethylhexyl)-phosphoric acid (D2EHPA)와 carbon nanotubes (CNTs)를 polysulfone (PSf)에 고정화시켜 PSf/D2EHPA/CNTs 비드를 제조하였으며, 제조한 비드에 의한 Sr(II)의 제거특성을 살펴보았다. Scanning electron microscopy (SEM), Fourier transform infrared spectrometer (FTIR) 및 Thermo gravimetric analysis (TGA) 분석을 통하여 PSf/D2EHPA/CNTs 비드의 형태적 특성들을 조사하였다. PSf/D2EHPA/CNTs 비드에 의한 Sr(II)의 제거는 운전시간 60 min 정도에서 평형에 도달하였으며, 속도 실험결과는 유사 2차 속도식에 잘 부합하는 것으로 나타났다. 또한 PSf/D2EHPA/CNTs 비드에 의한 Sr(II)의 제거에서 Langmuir 식으로부터 구한 최대 제거량은 4.75 mg/g이었다. PSf/D2EHPA/CNTs 비드에 의한 Sr(II)의 제거효율은 추출제 D2EHPA 만을 사용하는 경우보다 CNTs를 첨가함으로써 Sr(II)의 제거량이 2.5배 정도 향상되는 결과를 보였다. PSf/D2EHPA/CNTs beads were prepared by immobilizing extractant di-(2-ethylhexyl)- phosphoric acid (D2EHPA) and adsorbent carbon nanotubes (CNTs) on polysulfone (PSf), and the adsorption characteristics of Sr(II) on the beads were studied. The morphological characteristics of the prepared PSf/D2EHPA/CNTs beads were observed by scanning electron microscopy (SEM), thermo gravimetric analysis (TGA), and Fourier transform infrared spectrometer (FTIR). The equilibrium time for the removal of Sr(II) by PSf/D2EHPA/CNTs beads was 60 min. The experimental kinetic data followed pseudo-second-order model more than pseudo-first-order kinetics model. The maximum removal capacity of Sr(II) obtained from Langmuir isotherm was 4.75 mg/g. The removal efficiencies of Sr (II) by PSf/D2EHPA/CNTs beads were improved 2.5 times by adding the adsorbent CNTs more than by using only the extractant D2EHPA.

Yun Ho Jo,Hwan Lee,Myeong Hwan Oh,Gyeong Hee Lee,You Jin Lee,Ji Sun Lee,Min Jung Kim,Won Yong Kim,Jin Seong Kim,Dae Seok Yoo,Sang Won Cho,Seon Woo Cha,Mi Kyung Pyo 한국영양학회 2020 Nutrition Research and Practice Vol.14 No.4

BACKGROUND/OBJECTIVES: This study was designed to investigate the improvement effect of white ginseng extract (GS-KG9) on D-galactosamine (Ga1N)-induced oxidative stress and liver injury. SUBJECTS/METHODS: Sixty Sprague-Dawley rats were divided into 6 groups. Rats were orally administrated with GS-KG9 (300, 500, or 700 mg/kg) or silymarin (25 mg/kg) for 2 weeks. The rats of the GS-KG9- and silymarin-treated groups and a control group were then intraperitoneally injected Ga1N at a concentration of 650 mg/kg for 4 days. To investigate the protective effect of GS-KG9 against GalN-induced liver injury, blood liver function indicators, anti-oxidative stress indicators, and histopathological features were analyzed. RESULTS: Serum biochemical analysis indicated that GS-KG9 ameliorated the elevation of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), and lactate dehydrogenase (LDH) in GalN-treated rats. The hepatoprotective effects of GS-KG9 involved enhancing components of the hepatic antioxidant defense system, including glutathione, glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT). In addition, GS-KG9 treatment inhibited reactive oxygen species (ROS) production induced by GalN treatment in hepatocytes and significantly increased the expression levels of nuclear factor erythroid-2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) proteins, which are antioxidant proteins. In particular, by histological analyses bases on hematoxylin and eosin, Masson"s trichrome, α-smooth muscle actin, and transforming growth factor-β1 staining, we determined that the administration of 500 mg/kg GS-KG9 inhibited hepatic inflammation and fibrosis due to the excessive accumulation of collagen. CONCLUSIONS: These findings demonstrate that GS-KG9 improves GalN-induced liver inflammation, necrosis, and fibrosis by attenuating oxidative stress. Therefore, GS-KG9 may be considered a useful candidate in the development of a natural preventive agent against liver injury.

Objective: To compare laparoscopic surgery with conventional abdominal surgery in patients with early stage endometrial cancer. Methods: A retrospective review of 63 patients with early stage endometrial cancer managed between March 2003 and May 2005. Two groups were defined whether they had been treated by laparoscopy (case group: n=26) or by laparotomy (control group: n=37). We compared age, body mass index (BMI), hemoglobin change, operation time, number of pelvic lymph nodes, hospital stay, case with adjuvant treatment and recurrence between two groups. Results: There was no statistical difference in characteristics (age, BMI, nulliparity, previous abdominal surgery, FIGO stage, histologic grade). between case and control group. In addition, there was no statistical difference in operation data and outcomes between two groups. Hemoglobin changes were 1.1 g/dL (case group) vs 1.7 g/dL (control group) (p=0.072). Operation time was 131 min vs. 115 min. The numbers of lymph nodes obtained were 8.7 vs 7.7 (right) 9.2 vs. 7.6 (left). Hospital stays were 8.4 vs. 9.2 days. Adjuvant treatment cases were 7 vs. 15. Recurrent case was one in each group. Two patients initially evaluated by laparoscopy were converted to laparotomy due to bleeding and adhesion. Conclusion: Laparoscopic surgery for treatment of early endometrial cancer is a safe and effective alternative to laparotomy . However, long-term survival and risk of recurrence have yet to be determined.

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.
