가열 조건에 따른 단호박 페이스트를 제조하기 위해, 단호박을 15분 간 초벌 증숙한 뒤, 고압가열 처리 0분(A), 10분(B), 20분(C), 40분(D) 실시하여 실험군의 품질특성 을 조사하였다. 그 결과 일반성분의 경우, 대체적으로 고 압가열 처리 유무에 따른 유의적 차이가 관찰되었으며, 고압가열 처리한 B, C, D 실험군의 수분함량, 조단백질, 조섬유가 고압가열 무처리군 A에 비해 감소하였고, 가용성 무질소물은 증가하는 것으로 나타났다. 가열 조건별 단호박 페이스트의 수용성식이섬유는 고압가열 20분 처리군인 C의 측정치가 2.02로 가장 높았으며 무처리군인 A의 1.60 보다 증가하였고, 고압가열 처리 40분의 경우 오히려 감소하는 것으로 나타났다. 색도의 L 값은 고압가열 무처리군인 A가 52.20에서 고압가열 처리 10분, 20분, 40분으로 시간이 증가함에 따라 각각 50.33, 49.46, 48.06으로 감소하였고, a 값과 b 값 또한 유의적인 차이를 보이며 감소하였다. 현미경을 통한 단호박 페이스트의 현탁액 입자를 관찰한 결과 카로티노이드를 포함하는 유세포가 관찰되었으며 고압가열 처리와 그 시간이 증가함에 따라 단호박 유세포의 변형이 뚜렷하게 관찰되었으나, 부유안정성 실험 결과 실험군 A, B, C, D 간 차이가 없었다. 이때, 가열조건의 선택은 수용성 식이섬유의 증가, 환원당 증가, 단맛의 관능특성이 유의적으로 높고, 전반적 기호도가 가장 우수한 것으로 나타난 고압가열 처리 20분인 C 실험군으로 결정하였다. 선택된 조건의 단호박 페이스트에 식품가공 시 널리 사용되는 검류인 xanthan gum, locust bean gum, guar gum을 단호박 페이스트에 종류별로 첨가하여 부유안정성을 확인하였는데, 이 결과 guar gum, locust bean gum, xanthan gum 순으로 부유안정성 효과를 나타냈으며 locust bean gum과 xanathan gum은 비슷한 정도의 효과를 보였다. 또한 관능검사를 통한 기호도 확인 결과 텍스쳐와, 전반적인 기호도가 가장 우수했으므로 locust bean gum(0.2%) 첨가 단호박 라떼의 품질이 가장 적절할 것으로 판단된다. For the production of pumpkin paste with respect to heating conditions, we steamed the pumpkin for roughly 15 min, heated it with high pressure treatment for 0 min (A), 10 min (B), 20 min (C), 40 min (D), and subsequently investigated the quality characteristics. Generally a significant difference was observed between the pumpkin paste treated with and without high-pressure heat. The values of water content, crude protein and crude fiber of the high-pressure heat-treated groups B, C, D were decreased compared with untreated group A. The soluble fiber in experimental group B sweet-pumpkin paste treated with high-pressure heat for 20 min was higher than the control, and the highest value at 2.02. Experimental group D sweet-pumpkin paste treated with high-pressure heat for 40 min was found to have a decreased soluble fiber content relative to the control. The L value for the color of the group A untreated control sweet-pumpkin paste (no high-pressure heating) decreased as the time increased from 10 min to 40 min, with L values of 50.33, 49.46, and 48.06, respectively. The b value for the color of the sweet-pumpkin paste also decreased, showing a significant difference. Taking into account all the results, we chose experimental group B in order to prepare sweet-pumpkin latte. We used 0.2% gum (xanthan gum, locust bean gum, guar gum) as a stabilizer. Sweet-pumpkin latte with xanthan and locust bean gum has a suspension stability effect that lasts 90 min. The L and b values of sweet-pumpkin latte with gums increase and a value decrease compared with the control. In terms of the overall acceptance of the sweet-pumpkin latte, the experimental group with xanthan gum scored the best.

Ginsenoside Rg3 Suppresses Palmitate-Induced Apoptosis in MIN6N8 Pancreatic β-Cells

Kim, Kyong,Park, Min,Young Kim, Hye the Society for Free Radical Research Japan 2010 Journal of clinical biochemistry and nutrition Vol.46 No.1

<P>Chronic exposure to elevated levels of free fatty acids (FFA) causes β-cell dysfunction and may induce β-cell apoptosis in type 2 diabetes. The execution of β-cell apoptosis occurs through activation of mitogen-activated protein kinases (MAPKs). Ginsenoside Rg3 (Rg3), one of the active ingredients of ginseng saponins, has not been known about the effects on β-cell apoptosis mediated with FFA. The aims of this study were to investigate the <I>in vitro</I> protective effects of Rg3 on MIN6N8 mouse insulinoma β-cells against FFA-induced apoptosis, as well as the modulating effects on p44/42 MAPK activation. Our results showed that Rg3 inhibited the palmitate-induced apoptosis through modulating p44/42 MAPK activation. We conclude that Rg3 has the potential role in suppressing the progression of type 2 diabetes by inhibiting FFA-mediated loss of β-cells.</P>

Determination of the optimum porosity for 2‑CEES adsorption by activated carbon fiber from various precursors

Hye‑Min Lee,Byeong‑Hoon Lee,Ju‑Hwan Kim,Kay‑Hyeok An,Soo‑Jin Park,Byung‑Joo Kim 한국탄소학회 2019 Carbon Letters Vol.29 No.6

In this study, we prepared ACFs with a high specific surface area from various precursors (rayon, pitch, and oxidized polyacrylonitrile-based fibers) by a steam-activation technique and investigated the effects of the micropore and mesopore fraction on 2-CEES adsorption behaviors. The activation time was precisely controlled so that the activation yield was in the range of 35–40% to ensure the mechanical properties of the ACFs. The N2 adsorption isotherm characteristics at 77K were confirmed by Brunauer–Emmett–Teller, Barrett–Joyner–Halenda and non-local density functional theory equations. The adsorption capacities of the ACF were measured by breakthrough experiments in the gas phase (750 μg/mL of 2-CEES in N2 flow). The removal efficiency of the ACFs was evaluated and compared with that of AC. From the results, specific surface areas and total pore volume of the ACF were determined to be 1380–1670 m2/g and 0.61–0.82 cm3/g, respectively. It was also observed that various pore characteristics of ACF were found to be dependent on crystallite structure of each precursor. The break through time (C/C0 = 0.10) was in the order of Oxi-Pan-H-9-2 < Saratoga AC < Rayon-H-9-3 < Pitch-H-9-4. This indicates that 2-CEES adsorption capacity could be a function not only of specific surface area or total pore volume, but also of sub-mesopore volume fraction in the range of 1.5–2.5 nm of adsorbents.

Identification and Characterization of a Bacteriocin Produced by an Isolated Bacillus sp. SW1-1 that Exhibits Antibacterial Activity against Fish Pathogens

Kim, Young-Ok,Park, In-Suk,Kim, Dae-Jung,Nam, Bo-Hye,Kim, Dong-Gyun,Jee, Young-Ju,An, Cheul-Min The Korean Society for Applied Biological Chemistr 2014 Applied Biological Chemistry (Appl Biol Chem) Vol.57 No.5

The selected isolate, Bacillus sp. SW1-1 showed antibacterial activity against both Gram-positive and Gram-negative bacteria involved in fish diseases, including Edwardsiella tarda, Streptococcus iniae, S. parauberis, Vibrio anguillarum, and V. harveyi. The Maximum bacteriocin production was observed at $30^{\circ}C$ after 24 h with brain heart infusion medium (pH 7.0). The bacteriocin SW1-1 was purified by 50% ammonium sulfate precipitation, followed by HiPrep diethylaminoethyl 16/10 FF and Sephacryl S-100 High resolution column chromatography. The substance was characterized as a bacteriocin-like inhibitory substance with a molecular mass of 38 kDa. Bacteriocin SW1-1 was sensitive to the proteolytic action of pepsin, trypsin, chymotrypsin, and protease types I and XIV, and relatively heat labile, despite the fact that bacteriocin activity was still detected after heating at $100^{\circ}C$ for 30 min. The activity of bacteriocin SW1-1 was stable in the pH range of 2.0-11.0, and relatively unaffected by organic chemicals. The bacteriocin SW1-1 had a bacteriolytic mechanism, resulting in cell wall degradation of E. tarda. These characteristics indicate that this bacteriocin may be a potential candidate for alternative agent to control important pathogens of fish diseases in aquaculture.

김혜경,이지향,이상곤,반종석,민병우 대한마취과학회 2002 Korean Journal of Anesthesiology Vol.43 No.5

Background: This study was designed to determine the efficacy of a combined use of esmolol and nicardipine for blunting hypertension and tachycardia after tracheal intubation in hypertensive patients. Methods: Forty-five hypertensive patients were randomly divided into three group: group E (esmolol 0.5 mg/kg, n = 15), group N (nicardipine 30㎍/kg, n = 15), group EN (esmolol 0.25 mg/kg, nicardipine 15㎍/kg, n = 15). All patients received midazolam 0.5 mg/kg, and glycopyrrolate 0.2 mg IM for premedication. Fentanyl 1㎍/kg was injected before induction of anesthesia, and then esmolol, nicardipine, or the mixed drugs were administrated as an IV bolus and immediately followed by the induction drugs: thiopental 5 mg/kg, and succinylcholine 1 mg/kg. Endotracheal intubation was performed 90 seconds after injection of the experimental drugs. Thereafter 50% Nitrous Oxide in oxygen and 2 vol % enflurane were inhaled. BP and HR were recorded at the resting state, before fentanyl injection (base {T0}), after injection test drug (T1), after induction (T2), immediately after intubation (T3), 2 min (T4), 3 min (T5), 4 min (T6), and 5 min (T7) after intubation. Results: There was a significant attenuation in SBP, MBP, DBP after tracheal intubation on the nicardipine & mixed groups compared to the esmolol group. HR was significantly lower in the esmolol and mixed groups than in the nicardipine group after tracheal intubation. Conclusions: Combined administration of esmolol (0.25 mg/kg) and nicardipine (15㎍/kg) was effective in attenuating an increase of BP and HR during tracheal intubation in hypertensive patients.
