3주 동안 매일 200 mL의 녹용추출물 보충이 제2형 당뇨환자의 혈당수치, 혈장 지질 수준 및 항산화 영양상태 등에 미치는 영향을 알아보기 위하여, 당뇨환자군(10명)에게 중재연구를 수행하였다 3주 동안의 녹용추출물 섭취 후의 지질 수준을 섭취 전과 비교해 보면 당뇨환자군에게서 총 콜레스테롤, LDL-콜레스테롤 및 HDL-콜레스테롤 수준은 녹용추출물 섭취 전후에 변화가 나타나지 않았으나 혈장 중성지방의 평균수준은 녹용섭 취 후에 다소 낮아지는 경 향을 보였다. 혈장 내 LDL의 산화정도에 영향을 미치는 혈장 평균 CD수준은 녹용 추출물 섭취 전 53.78kl.75 UmoyL에서 섭취 후 51.03$\pm$1.30 $\mu$mol/L로 약 5% 정도의 유의적인 감소를 보였다. 녹용추출물 섭취 후 대상자에게서 혈장 항산화 비타민농도, 총항산화능인 TRAP 수준 및 항산화 효소 활성도의 변화가 나타나지 않았다. 녹용추출물 섭취 전과 후에 환자군의 혈장 GOT와 GPT 수준은 변화가 없었다. 본 연구결과 녹용 섭취 후 당뇨환자의 혈장 CD값이 감소하였으므로 이런 결과가 당뇨환자의 항산화 상태의 개선과 관련이 있을 것으로 기대하였으나 항산화 상태의 향상이 나타나지 않은 것으로 보아 당뇨환자에게서 녹용추출물 섭취 후에 나타났던 CD 감소효과는 항산화와는 다른 기전이 관련되어 있는 것으로 보여진다. 최근 우리나라에도 당뇨병 환자가 증가하는 것과 더불어 건강기능식품에 대한 관심이 증대하고 있으므로 앞으로 당뇨환자의 LDL 산화 정도를 개선하는 영양중재 연구 및 건강기능식품에 관한 연구가 보다 폭 넓고 다양하게 이루어져야 하리라고 생각된다.

A bacterial strain, designated B301^T and isolated from raw chicken meat obtained from a local market in Korea, was characterized and identified using a polyphasic taxonomic approach. Cells were gram-negative, non-motile, obligate-aerobic coccobacilli that were catalase-positive and oxidase-negative. The optimum growth conditions were 30℃, pH 7.0, and 0% NaCl in tryptic soy broth. Colonies were round, convex, smooth, and cream-colored on tryptic soy agar. Strain B301^T has a genome size of 3,102,684 bp, with 2,840 protein-coding genes and 102 RNA genes. The 16S rRNA gene analysis revealed that strain B301^T belongs to the genus Acinetobacter and shares highest sequence similarity (97.12%) with A. celticus ANC 4603^T and A. sichuanensis WCHAc060041^T. The average nucleotide identity and digital DNA-DNA hybridization values for closely related species were below the cutoff values for species delineation (95-96% and 70%, respectively). The DNA G+C content of strain B301^T was 37.0%. The major respiratory quinone was Q-9, and the cellular fatty acids were primarily summed feature 3 (C_16:1 ω6c/C_16:1 ω7c), C_16:0, and C_18:1 ω9c. The major polar lipids were phosphatidylethanolamine, diphosphatidyl-glycerol, phosphatidylglycerol, and phosphatidyl-serine. The antimicrobial resistance profile of strain B301^T revealed the absence of antibiotic-resistance genes. Susceptibility to a wide range of antimicrobials, including imipenem, minocycline, ampicillin, and tetracycline, was also observed. The results of the phenotypic, chemotaxonomic, and phylogenetic analyses indicate that strain B301^T represents a novel species of the genus Acinetobacter, for which the name Acinetobacter pullorum sp. nov. is proposed. The type strain is B301^T (=KACC 21653^T = JCM 33942^T).

식이 셀레늄(Se)의 수준과 식이지방산의 조성이 조직(혈장,동맥,간)의 지질과산화 상태와 조직의 지방산 조성에 미치는 영향에 대해 연구하였다. Sprague Dawley종 수컷쥐들을 식이 Se 수준(0.005mg/kg diet, 0.5mg/kg diet)과 식이 지방산의 주요 급원(옥수수유, 어유)에 따라 4군으로 나누어 8주간 실험하였다. 식이에 함유된 vitamin E의 함량은 117IU정도이다. Se 영양상태의 지표인 glutathione peroxidase 활성도와 Se 수준은 Se이 결핍된 식이를 공급시키면 식이지방 종류에는 상관없이 낮게 나왔다. 어유공급은 간과 동맥의 MDA를 증가시키나 Se을 공급시킨 쥐의 간 MDA수준은 감소되었다. 어유를 공급시키면 혈장 총치질, 동맥 과 간의 인지질에서 20:5(n-3), 22:5(n-3), 22:6(n-3), 20:3(n-6) 수준은 증가하였으며 20:4(n-6)수준은 감소되었다. 비록 Se공급이 n-3 지방산 수준 [22:6(n-3)]을 증가시키나 어유공급 효과에 비하면 그 효과가 적었다. 본 실험결과에 의하면 vitamin E가 현재 권장되는 양보다 충분히 많게 공급되어도 Se이 지질과산화를 방지하는데 중요한 역활을 하고 있으므로 적절한 Se공급이 바람직하다.

BACKGROUND/OBJECTIVES: Type 2 Diabetes mellitus (T2DM) is a hereditary disease that is also strongly dependent on environmental factors, lifestyles, and dietary habits. This study explored the relationship between lifestyle habits and glycosylated hemoglobin management in T2DM patients to provide empirical outcomes to improve T2DM management and patient health literacy. SUBJECTS/METHODS: This study enrolled 349 diabetic patients with more than 5 care visits to a Diabetes Mellitus care network under the Health Management Plan led by Taiwan Department of Health (DOH). Based on relevant literature, an Outpatient Record Form of Diabetes Mellitus Care was designed and lipid profile tests were conducted for data collection and analysis. RESULTS: When modeling the data, the results showed that the odds for HbA1c > 7.5% in T2DM patients duration over 10 years was 3.785 (P = 0.002) times that in patients with disease duration of fewer than 3 years. The odds of HbA1c > 7.5% in illiterate patients was 3.128 (P = 0.039) times that in patients with senior high school education or above. The odds of HbA1c > 7.5% in patients with other chronic illness was 2.207 (P = 0.019) times that in participants without chronic illness. Among 5 beneficial lifestyle habits, the odds of HbA1c > 7.5% in patients with 2 or 3 good habits were 3.243 (P = 0.003) and 3.424 (P = 0.001) times that in patients with more than 3 good habits, respectively. CONCLUSION: This empirical outcome shows that maintaining a good lifestyle improves T2DM management and patients' knowledge, motivation, and ability to use health information. Patients with longer disease duration, education, or good lifestyle habits had optimal HbA1c management than those in patients who did not. Thus, effective selfmanagement and precaution in daily life and improved health literacy of diabetic patients are necessary to increase the quality of T2DM care.

Objective: We investigated the efficacy of a 12-week supplementation of soy isoflavone with L-carnitine on the development of obesity in high fat-induced obese C57BL/6J mice, which are known as a good model of diet-induced obesity. Methods: We measured body weights, adipose tissue mass, serum/liver lipid profiles and fat cell size/number in C57BL/6J mice fed diets containing either low fat (4%) or high fat (35%), or high fat supplemented with soy isoflavone powder containing 10% isoflavone and L-camitine for 12 weeks. Results: Body weight gain, abdominal adipose tissue and liver weight were lower by 31% 78% and 31.4% respectively, in mice on high fat diet containing soy isoflavone+L-carnitine (SC mixture) compared with high fat diet group. Also, SC mixture improved serum lipid profiles such as total cholesterol (TC), triglycerides (TG), and liver lipid profiles such as total lipids and TG. As subsequent results, this SC mixture prevented high-fat diet from accumulating TG in the liver. The size of fat cell was also significantly decreased in SC mixture fed mice. At the end point of this experiment, our results showed that feeding with soy isoflavone for 12 weeks finally increased camitine palmitoyltransferase 1 (CPT 1) activity through elevating the level of CPT1 expression. Conclusions: This study suggests that long-tenn supplementation with dietary soy isoflavone and L-carnitine is more synergistically beneficial for the suppression of high-fat diet induced obesity by inhibiting liver TG accumulation and the gain in abdominal adipose tissue weight than that with soy isoflavone. The antiobesity effects of SC mixture might be attributed, at least in part, to the induction of fatty acid catabolism by soy isoflavone, genistein.

This study investigated the effects of dietary supplementation of cheese byproduct on performance, egg quality and fatty acid profile of egg yolk lipids from laying hens. One hundred five 30-wk-old White leghorn laying hens were randomly distributed into five groups of twenty one hens each and maintained in individual laying cages for 4 weeks. The hens were assigned to five treatments that consisted of corn-soybean meal based diets containing 0, 1, 3, 5 or 10% of cheese byproduct. Feed intake and rate of egg production of hens were not significantly different across the treatments during the whole experiment (p>0.05). Similarly, egg yolk cholesterol level, egg weight, Haugh's unit, eggshell thickness, color, and strength were not significantly different across the treatments (p>0.05). The amount of C16:0 in egg yolk was not significantly different across the treatments, but that of C18:0 decreased with increased cheese byproduct (p<0.01). Monounsaturated fatty acid (C16:1 and C18:1) content in egg yolk was similar across the treatments. Total CLA and cis-9, trans-11 CLA content increased linearly with increased cheese byproduct (p<0.001), while trans-10, cis-12 CLA amount was not significantly different across the treatments (p>0.05). Total saturated fatty acid (SFA) in the egg yolk was decreased as the level of cheese byproduct including CLA increased (p<0.01). However, the amount of unsaturated fatty acids (UFA) such as monounsaturated fatty acids (MUFA), n-3 polyunsaturated fatty acids (PUFA), n-6 PUFA, and total PUFAs in the egg yolk were not significantly different across the treatments (p>0.05). Therefore, the present results showed that cheese byproduct beneficially improved the fatty acid composition of concern to human health in the egg yolk without adverse effects on egg quality.

In this study, we designed to confirm the dietary effect of anti-obesity of fermented soybean curd residue (FSCR; SCR-Meju; Biji-meju) by A. oryzae, which is well known as a Korean traditional meju microbe. We observed that body weight gain, serum and hepatic lipid profile, as well as the activity of ROS generating enzyme and ROS scavenging enzyme in high-fat diet induced obese mice fed experimental diet (SCR and SCR-meju). Body weight gain and epididymal fat weight of HC (high-fat diet control) was markedly higher than that of NC (Normal control). Conversely, body weight gain and epididymal fat weight of the SCR (Biji) and SCR-meju (Biji-meju) group was significantly lower than that of HC; these of the SCR-meju group was lower than that of the SCR group. Furthermore, serum TG and total-cholesterol and LDL-cholesterol contents of SCR and SCR-meju groups were lower than that of HC, and HDL-cholesterol level of the SCR-meju group was significantly higher than that of HC. In conclusion, although precise mechanisms of the antiobese effects of SCR-meju in this study are unknown, the present study provides an experimental evidence that SCR-meju may prevent obesity and obesity related metabolic syndromes, such as hyperlipidemia, hypertension and diabetes, and liver disease by high-fat diet. Nevertheless, further study in this filed will be needed.

Chitosan-ascorbate (CA)를 표면처리한 후 $40{\sim}60^{\circ}C$에서 감압건조한 과메기(VD-과메기)의 품질특성과 고지방식이 흰쥐의 혈청지질과 항산화계 효소활성에 미치는 영향을 조사하였다. VD-과메기의 제조기간은 $4.5{\sim}8.3시간, 자연건조과메기(ND-과메기)의 제조기간 $360{\sim}480$시간이었다. 총 균수는 VD-과메기에서는 $0.2{\sim}0.5$ log CFU/g, ND-과메기에서는 8.2 log CFU/g였다. 아미노태질소 함량은 $128.3{\sim}135.0$mg%로 ND-과메기와 VD-과메기의 뚜렷한 차이가 없었다. VD-과메기는 ND-과메기에 비하여 산가와 과산화물가가 현저하게 낮으며 비린내가 적고 조직감, 색상 및 종합적기 호도가 높았으며 종합적으로는 $40^{\circ}C$에서 제조한 VD-40-과메기가 가장 우수하였다. 고지방식이 흰쥐에 감압건조한 VD-40-과메기를 10% 혼합하여 4주간 급여한 군 (HVK)은 ND-과메기에 비하여 증체량이 낮고, 혈청 HDL-cholesterol 함량은 높은 반면 total cholesterol과 LDL-cholesterol함량이 낮았으며, glutathione 함량은 뚜렷한 차이가 없으나 lipid peroxide 함량은 현저하게 낮았다. 또한 고지방식이로 증가된 간의 xanthine oxidase total 및 O type 활성도 및 O/T(%)를 유의적으로 감소시켰다. 이상의 결과, 과메기 제조시 CA를 처리한 후 $40^{\circ}C$서 감압건조하는 방법은 제조기간을 크게 단축시킬 뿐만 아니라 과메기의 위생성과 영양성을 높일 수 있는 방법으로 산업적 활용이 기대된다.

This study was conducted to evaluate the effect of high-oleate and normal-oleate peanut consumption on adipose mass and serum lipids in obese-induced C57BL/6J mice. After four weeks of the high-fat diet, mice were randomly divided into six groups: normal control (NC) diet, high-fat control (HFC) diet, high-oleate peanut-seed (HOPS) diet, normal-oleate peanut-seed (NOPS) diet, high-oleate peanut-oil (HOPO) diet, and olive-oil (OO) diet. After four weeks, all four experimental diet groups showed significantly lower body weight and epididymal fat weight than HFC group. In four experimental diet groups, serum triglycerides (TG), total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) were significantly lower, and high-density lipoprotein cholesterol (HDL-C) was significantly higher than HFC group. TG was significantly decreased in HOPS group (92.1±1.2 mg/dL) than NOPS group (101.7±5.3 mg/dL, p<0.05). Similarly, LDL-C was significantly lower in HOPS group (66.1±2.8 mg/dL) than NOPS (76.9±1.5 mg/dL, p<0.05), on the other hand, HDL-C indicated a significant elevation in HOPS (50.5±2.1 mg/dL) than NOPS group (45.2±1.6 mg/dL, p<0.05). This result suggests that the consumption of high-oleate peanut has a favorable effect on the plasma lipid profile.
