Objectives : This study mean to confirm the antibacterial activity of a garlic extract widely culturing in our region and was to determine the effect of dentifrice containing 0.1% extracts of garlic on dental plaque and gingivitis in a double blind and clinical studies in 50 healthy adults aged from 20 to 22 years who provided a consent for their participation. Methods : The antibacterial activity was evaluated using triple distilled water and the Kirby-Bauer disk diffusion method and the minimal inhibitory concentration(MIC) against various pathogens for periodontal disease, such as P. gingivalis 381(ATCC33277), was estimated. The experimental groups classified according to the concentration of garlic extract used: 10,000ppm(A), 5,000ppm(B), 2,500ppm(C), 1,000ppm(D). Oral examination of subjects was performed through clinical periods and on day of baseline, 6, 12, 19, 25 days plaque index and gingival index were scored by Turesky' modified index and Loe & Silness index. After 12, 19, 25 days use of their respective dentifrices, statistically decreases of plaque index, gingival index were shown in both the experimental and the control group, respectively. Results : There was significant antibacterial activity in the "2,500ppm(C)" group against P. gingivalis 381. Experimental group exhibited significantly the lower plaque levels and the higher levels of gingival health by the use of the dentifrices contained extract of garlic from 6 days compare with control group(p<0.05). The degree of decrease was more significant on gingivitis level of the experimental group than the control group(p<0.05). Conclusions : This findings indicated that the oral products containing a garlic extract is effective in preventing and treating periodontal diseases, and has potential value in inhibiting periopathogens.

BACKGROUND/OBJECTIVES: In this study, the apoptogenic activity and mechanisms of cell death induced by hexane extract of aged black garlic (HEABG) were investigated in human leukemic U937 cells. MATERIALS/METHODS: Cytotoxicity was evaluated by MTT (3-(4, 5-dimethyl-thiazol-2-yl)-2, 5-diphenyl tetrazoliumbromide) assay. Apoptosis was detected using 4,6-diamidino-2-phenyllindile (DAPI) staining, agarose gel electrophoresis and flow cytometry. The protein levels were determined by Western blot analysis. Caspase activity was measured using a colorimetric assay. RESULTS: Exposure to HEABG was found to result in a concentration- and time-dependent growth inhibition by induction of apoptosis, which was associated with an up-regulation of death receptor 4 and Fas legend, and an increase in the ratio of Bax/Bcl-2 protein expression. Apoptosis-inducing concentrations of HEABG induced the activation of caspase-9, an initiator caspase of the mitochodrial mediated intrinsic pathway, and caspase-3, accompanied by proteolytic degradation of poly(ADP-ribose)-polymerase. HEABG also induced apoptosis via a death receptor mediated extrinsic pathway by caspase-8 activation, resulting in the truncation of Bid, and suggesting the existence of cross-talk between the extrinsic and intrinsic pathways. However, pre-treatment of U937 cells with the caspase-3 inhibitor, z-DEVD-fmk, significantly blocked the HEABG-induced apoptosis of these cells, and increased the survival rate of HEABG-treated cells, confirming that HEABG-induced apoptosis is mediated through activation of caspase cascade. CONCLUSIONS: Based on the overall results, we suggest that HEABG reduces leukemic cell growth by inducing caspase-dependent apoptosis through both intrinsic and extrinsic pathways, implying its potential therapeutic value in the treatment of leukemia.

In this study, we investigated the hepatoprotective effects of aged black garlic (ABG) in rodent models of liver injury. ABG inhibited carbon tetrachloride-induced elevation of aspartate transaminase (AST) and alanine transaminase (ALT), which are markers of hepatocellular damage, in SD rats. D-galactosamine-induced hepatocellular damage was also suppressed by ABG treatment. However, ABG does not affect the elevation of alkaline phosphatase (ALP), a marker of hepatobilliary damage, in rats treated with carbon tetrachloride or D-galactosamine. We also examined the effect of ABG on high-fat diet (HFD)-induced fatty liver and subsequent liver damage. ABG had no significant effect on body weight increase and plasma lipid profile in HFD-fed mice. However, HFD-induced increase in AST and ALT, but not ALP, was significantly suppressed by ABG treatment. These results demonstrate that ABG has hepatoprotective effects and suggest that ABG supplementation might be a good adjuvant therapy for the management of liver injury.

본 연구에서는 흑마늘 열수 추출물(ABG)의 암세포 전이억제 효능을 검정하였다. AGS AGS 인체위암세포의 이동성과 침윤성을 억제하였으며, 이는 TER의 증가와 연관성이 있었다. 또한 ABG에 의한 AGS 위암세포의 침윤성 억제는 TIMPs 발현 증가에 의한 MMPs의 발현 및 활성 저하에 의한 것임을 알 수 있었다. 아울러 AGS 위암세포에서 과발현을 나타내는 TJ 단백질인 claudins의 발현 저하 등이 ABG의 항전이 효과에 연관되어 있음을 알 수 있었다. 이상의 결과는 흑마늘 열수 추출물이 단순한 암세포의 증식억제를 통한 암예방 및 항암활성 뿐만 아니라 암세포의 전이 또한 효과적으로 억제할 수 있음을 보여주며, 이와 연관된 보다 구체적인 분자세포생물학적 접근 및 in vivo 연구의 필요성이 요구됨을 의미한다.

BACKGROUND/OBJECTIVES: Irisin, a newly identified hormone, is associated with energy homeostasis. We investigated whether aged garlic extract (AGE) and exercise training intervention could improve body weight, insulin sensitivity, skeletal muscle fibronectin domain containing protein 5 (FNDC-5) levels, and plasma irisin in high-fat diet (HFD). MATERIALS/METHODS: Male Sprague Dawley rats were fed a ND (normal diet, n=5) or HFD (n=28) for 6 weeks. After 6 weeks, all rats were divided into 5 groups for the next 4 weeks: ND, (normal diet, n=5), HFD (high-fat diet, n=7), HFDA (high-fat diet + aged garlic extract, n=7), HFDE (high-fat diet + exercise, n=7), and HFDEA (high-fat diet + exercise + aged garlic extract, n=7). Exercise groups performed treadmill exercises for 15-60 min, 5 days/week, and AGE groups received AGE (2.86 g/kg, orally injected) for 4 weeks. RESULTS: Significant decreases in body weight were observed in the ND, HFDE, and HFDEA groups, as compared with the HFD group. Neither intervention affected the masses of the gastrocnemius muscle or liver. There were no significant differences in glucose levels across the groups. The homeostatic model assessments of insulin resistance were significantly higher in the HFD group, as compared with the ND, HFDA, HFDE, and HFDEA groups. However, skeletal muscle FNDC-5 levels and plasma irisin concentrations were unaffected by AGE or exercise in obese rats. AGE supplementation and exercise training did not affect skeletal muscle FNDC-5 or plasma irisin, which are associated with insulin sensitivity in obese rats. CONCLUSION: Our results suggest that the protection against HFD-induced increases in body fat/weight and insulin resistance that are provided by AGE supplementation and exercise training may not be mediated by the regulation of FNDC-5 or irisin.

Aged garlic extract (AGE) is known to have a protective effect against immune system, endothelial function, oxidative stress and inflammation. We examined the effects of exercise with and without aged garlic extract administration on body weight, lipid profiles, inflammatory cytokines, and oxidative stress marker in high-fat diet (HFD)-induced obese rats. Forty-five Sprague-Dawley rats were fed either a HFD (HFD, n = 40) or a normal diet (ND, n = 5) for 6 weeks and thereafter randomized into ND (n = 5), HFD (n = 10), HFD with AGE (n = 10), HFD with Exercise (n = 10), or HFD with Exercise+AGE (n = 10) for 4 weeks. AGE groups were administered at a dose of 2.86 g/kg body weight, orally. Exercise consisted of running 15-60 min 5 days/week with gradually increasing intensity. AGE (P<0.01), Exercise, and Exercise+AGE (P<0.001) attenuated body weight gain and food efficiency ratio compared to HFD. Visceral fat and liver weight gain were attenuated (P<0.05) with all three interventions with a greater effect on visceral fat in the Exercise+AGE than AGE (P<0.001). In reducing visceral fat (P<0.001), epididymal fat (P<0.01) and liver weight (P<0.001), Exercise+AGE was effective, but exercise showed a stronger suppressive effect than AGE. Exercise+AGE showed further additive effects on reducing visceral fat and liver weight (P<0.001). AGE significantly attenuated the increase in total cholesterol and low-density lipoprotein-cholesterol compared with HFD (P<0.05). Exercise+AGE attenuated the increase in triglycerides compared with HFD (P<0.05). Exercise group significantly decrease in C-reactive protein (P<0.001). These results suggest that AGE supplementation and exercise alone have anti-obesity, cholesterol lowering, and anti-inflammatory effects, but the combined intervention is more effective in reducing weight gain and triglycerides levels than either intervention alone.

자이언트마늘을 자이언트흑마늘로 숙성시킬 시에 새롭게 생성되거나 증강되는 유효성분을 측정하여 기존의 일반마늘 및 이를 숙성시킨 일반흑마늘과 비교 분석하였다. 일반성분 분석 결과 자이언트마늘에서 자이언트흑마늘로 숙성 후 수분은 감소하였으며 회분, 조단백, 조지방은 증가하였고, 일반마늘에서 일반흑마늘로 숙성 후에도 유사한 경향을 보였다. pH는 숙성 후 감소하였고 산도는 증가하는 경향을 보였다. 총당은 숙성 후 증가했지만 자이언트흑마늘과 일반흑마늘 간에 큰 차이가 없었으며 환원당의 경향도 유사하였다. 총 피루브산의 함량은 숙성 후에 증가하는 것을 볼 수 있었으며, 자이언트흑마늘이 일반흑마늘에 비하여 더 높은 값을 나타냈다. 구성 아미노산 측정 결과 자이언트마늘이 자이언트흑마늘로 숙성 후에 histidine, lysine, arginine을 제외한 모든 아미노산이 많게는 2배 이상 증가하였으며, 자이언트흑마늘이 일반흑마늘보다 숙성 후 총 아미노산 함량의 증가비율이 더 높았다. 자이언트흑마늘이 일반흑마늘보다 arginine, cysteine, lysine, phosphoethanolamine, urea를 제외한 유리 아미노산의 함량이 더 높은 값을 나타냈으며 자이언트마늘이 자이언트흑마늘로 숙성 후에 taurine, phosphoethanolamine, ${\beta}$-alanine, ethanolamine이 신규 생성 되었다. 무기질의 측정 결과 자이언트마늘이 자이언트흑마늘로 숙성 후에 구리, 철, 마그네슘, 나트륨이 증가하였다. S-Allyl-L-cysteine의 함량은 자이언트흑마늘이 자이언트마늘에 비해 약 4배 증가했으며 일반흑마늘보다 높은 값을 나타내었다. S-Allylmercaptocysteine도 마찬가지로 숙성시에 함량이 크게 증가하는 것을 확인할 수 있었다. 따라서 본 연구 결과는 자이언트마늘의 가공에 대한 기초자료로써 활용될 수 있을 것으로 사료된다.

The effects of fermented garlic powder on production performance, egg quality, blood profiles and fatty acid composition of egg yolk in laying hens were studied in a 35-d experiment. Two-hundred and forty (ISA brown) layers aged 41 weeks were randomly allocated into the following four treatments: i) CON (basal diet); ii) G1 (CON+fermented garlic powder 1.0%); iii) G2 (CON+fermented garlic powder 2.0%) and iv) G3 (CON+fermented garlic powder 3.0%). There were no differences (p>0.05) among treatments in egg production, egg weight, eggshell breaking strength and eggshell thickness throughout the whole experimental period. However, yolk height was increased significantly (p<0.05) by the addition of fermented garlic powder during the 5th week while yolk color was greater (p<0.05) in G2 and G3 than in CON and G1 in the 5th week. Compared with CON, Haugh unit was increased (p<0.05) in response to fermented garlic powder treatments during the 5th week. No significant effects on total protein, albumin and IgG were observed in response to any of the treatments over the experimental period (p>0.05). There was a significant (p<0.05) reduction in plasma cholesterol concentration when the dietary level of fermented garlic powder was increased from 0.0 to 3.0%. The levels of saturated fatty acids (SFA) were significantly decreased (p<0.05) in response to G2 and G3 while monounsaturated fatty acids (MUFA) were higher (p<0.05) in G2 and G3 treatment groups than in CON and G1. Compared with other treatments, polyunsaturated fatty acids (PUFA) and PUFA:SFA ratio were higher (p<0.05) in G3. In conclusion, this study demonstrated that addition of fermented garlic powder reduced plasma cholesterol concentration and did not cause adverse effects on production performance. Moreover, addition of 3.0% garlic powder decreased SFA but increased PUFA and PUFA:SFA ratio in egg yolk.

본 연구는 흑마늘 숙성기간 중의 흑마늘의 지표물질이라 할 수 있는 S-allylcysteine (SAC)의 함량을 측정한 다음 흑마늘 추출물이 고지방식이로 유발된 흰쥐에 미치는 영향을 조사하였다. 흑마늘을 10일, 15일 및 20일 숙성 중 S-allylcysteine의 함량은 15일 일 때가 가장 높았으며, 관능검사 결과도 숙성 15일째가 좋았다. 고지방 식이만 공급된 동물군을 정상군, 위약군 그리고 고지방식이에 흑마늘 추출물의 첨가 농도에 따라 저농도군, 중농도군 및 고농도군으로 5그룹으로 나누어 6주간 사육하였다. 정상군, 실험군 모두 체중은 지속적으로 증가하였으나 그룹 간의 유의적 차이는 없었고 흑마늘 추출물 첨가 급이군이 정상군에 비하여 체중 및 식이 효율에 유의적 차이는 없었다. 혈중 총지질은 흑마늘 추출물의 첨가 농도에 관계없이 감소하였으며, 총 콜레스테롤 및 중성지방도 흑마늘 추출물의 첨가 농도가 높을수록 유의적으로 감소하였다. 흑마늘 추출물 급이에서도 정상군에 비하여 HDL-콜레스테롤이 유의적으로 증가하였고 LDL-콜레스테롤은 감소하였다. 간의 총지방, 총 콜레스테롤 및 중성 지방의 함량은 정상군에 비하여 흑마늘 추출물을 급이한 저농도, 중농도, 고농도 군에서 모두 감소되는 경향을 나타내었다. 이상의 실험결과를 보면, 6주 동안 고지방식이로 유도된 고 콜레스테롤혈증은 동물 실험에서 흑마늘 추출물 첨가가 저농도, 중농도 및 고농도에서 혈액과 간의 중성 지방과 총콜레스테롤을 감소하는 효과가 있었으므로 체내지질 개선효과를 갖는 식품 소재로서의 가능성이 있음을 확인할 수 있었다.
