  • The purpose of the present study was to determine the effect of a chewing gum containing 70% xylitol and 0.23% Curcuma xanthorrhiza extract to remove dental plaque and reduce gingivitis when used as a supplement to daily toothbrushing for 3 weeks. The study group consisted of 75 adults with moderate gingvitis. Participants were divided into 3 groups(contol 1 group - Gum base, contol 2 group - 70% Xylitol, experiment group - 70% xylitol and 0.23% xanthorrhizol) and instructed to chew the study gum for 3 times daily for 3 weeks in addition to regular daily toothbrushing. Chewing xylitol/xanthorrhizol gum significantly reduced plaque index with significant difference by week 3(p<0.01). Gingival index and bleeding on probing were decreased in xy/ Curcuma xanthorrhiza extract group by 35.9% and 31.65% each in the same period. No adverse effects on the oral tissues were observed in any of the participants for the duration of the study. In conclusion, regular use of a chewing gum containing 70% xylitol and 0.23% Curcuma xanthorrhiza extract appears safe and effective for the removal of dental plaque and reduction of gingivitis when used in conjunction with daily toothbrushing.

  • After harvesting the medicinal parts of Curcuma longa, the remaining underground parts were discarded. From the remaining underground parts of Curcuma longa quercetin-3-O-${\beta}$-D-glucopyranoside-7-O-${\alpha}$-L-rhamnopyranoside (Q37) was isolated. The antioxidant activities in vitro and lifespan-extension effect of Q37 were elucidated using the Caenorhabditis elegans. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging effect of Q37 showed similar potent activities in comparison with vitamin C. Q37 also showed potent superoxide quenching activities as measured by the riboflavin- and xanthine-originated superoxide quenching activity tests. Q37 prolonged lifespan of worms under normal culture condition. In terms of protective effect of Q37 on the stress conditions such as thermal and oxidative stresses, Q37-treated worms exhibited enhanced survival rate, as compared to control worms. To know the possible mechanism of Q37-mediated increased lifespan and stress resistance of worms, we examined the activities of Q37on superoxide dismutase (SOD), and invested intracellular reactive oxygen species (ROS) levels. The results revealed that Q37 was able to elevate SOD activity of worms and reduce intracellular ROS accumulation in a dose-dependent manner.

  • 본 연구는 쌀가루 첨가량을 달리하여 울금 쿠키를 제조한 다음 이화학적 및 관능적 품질 특성을 조사하였다. 쿠키 반죽의 밀도는 대조군이 1.32로 가장 높았고 유의적인 차이가 있었다. 쿠키 반죽의 pH는 쌀가루 첨가량이 증가함에 따라 증가하는 경향을 보였다. 쿠키의 수분함량은 쌀가루 첨가량이 증가함에 따라 증가하였다. 쿠키의 퍼짐성 지수는 쌀가루 첨가군이 유의적으로 감소하였다(p<0.001). 쌀가루 첨가 울금 쿠키의 DPPH radical 소거능을 측정한 결과 대조군(58.72%)보다 쌀가루 첨가군(59.26~61.41%)이 유의적으로 높았다(p<0.001). 쿠키의 색도에서 명도 L값은 쌀가루 첨가량이 증가할수록 증가하였으나(p<0.001) 적색도 a값과 황색도 b값은 쌀가루 첨가량이 증가할수록 낮아졌다(p<0.001). 쿠키의 경도(hardness)는 쌀가루 첨가군보다 대조군이 더 높았다(p<0.001). 쿠키의 외관, 향, 맛, 조직감 및 전반적인 기호도에서 관능평가 점수가 쌀가루 50% 첨가군, 75% 첨가군 순으로 높게 나타났다. 이와 같은 결과 울금을 이용한 쌀쿠키 제조에 있어서 쌀가루 첨가비율은 50~75%가 최적의 배합비율로 사료된다.

  • Previous work demonstrated that an ethanol extract (HS0608) of a mixture of three medicinal plants of Curcuma longae radix, Phellinus linteus, and Scutellariae radix markedly inhibits $A{\beta}$ (25-35)-induced neurotoxicity. The present study was performed to further verify the neuroprotective effect of HS0608 on oxidative and ischemic cerebral injury using cultured rat cortical neurons and rats. Exposure of cultured cortical neurons to $100\;{\mu}M$ hydrogen peroxide ($H_2O_2$) induced neuronal apoptotic death. At $10-100{\mu}g/ml$, HS0608 inhibited neuronal death, elevation of intracellular calcium concentration ($[Ca^{2+}]_i$), and generation of reactive oxygen species (ROS) induced by $H_2O_2$ in primary cultures of rat cortical neurons. In vivo, HS0608 prevented cerebral ischemic injury induced by 2-h middle cerebral artery occlusion (MCAO) and 24-h reperfusion. The ischemic infarct and edema were significantly reduced in rats that received HS0608 (200 mg/kg). These results suggest that the anti-oxidative properties of HS0608 may be responsible for its neuroprotective effect against focal cerebral ischemic injury and that HS0608 may have a therapeutic role in neurodegenerative diseases such as stroke.

  • The overproduction of nitric oxide (NO) by inducible nitric oxide synthase (iNOS) is known to be responsible for vasodilation and hypotension observed in septic shock and inflammation. Inhibitors of iNOS, thus, may be useful candidates for the treatment of inflammatory diseases accompanied by overproduction of NO. In the course of screening oriental anti-inflammatory herbs for the inhibitory activity of NO synthesis, a crude methanolic extract of Curcuma zedoaria exhibited significant activity. The activity-guided fractionation and repetitive chromatographic procedures with the EtOAc soluble fraction allowed us to isolate three active compounds. They were identified as 1,7-bis (4-hydroxyphenyl)-1,4,6-heptatrien-3-one (1), procurcumenol (2) and epiprocurcumenol (3) by spectral data analyses. Their concentrations for the 50% inhibition of NO production $(IC_{50})$ in lipopolysaccharide (LPS)-activated macrophages were 8, 75, 77 ${\mu}M$, respectively. Compound 1 showed the most potent inhibitory activity for NO production in LPS-activated macrophages, while the epimeric isomers, compound 2 and 3 showed weak and similar potency. Inhibition of NO synthesis by compound 1 was very weak when activated macrophages were treated with 1 after iNOS induction. In the immunoblot analysis, compound 1 suppressed the expression of iNOS in a dose-dependent manner. In summary, 1,7-bis (4-hydroxyphenyl)-1,4,6-heptatrien-3-one from Curcuma zedoaria inhibited NO production in LPS-activated macrophages through suppression of iNOS expression. These results imply that the traditional use of C. zedoaria rhizome as anti-inflammatory drug may be explained at least in part, by inhibition of NO production.

  • Objectives: This clinical trial is performed to investigate the effect of improving the menopausal symptoms and the safety of extract obtained from Pueraria thunbergiana Bentham and Curcuma longa L. in menopausal women Methods: This study was randomized, double blinded, placebo-controlled clinical trial. 110 women with menopausal symptoms were assigned to treatment group (n=55) and control group (n=55). The results of this study were evaluated through changes in Kupperman Index score, Menopause-specific Quality of Life Questionnaire (MENQOL) score, degree of hot flashes and sweating, Body Mass Index(BMI), laboratory test results including female hormones. Results: In the treatment group compared to before baseline, there was significant difference in the Kupperman Index total score, score of each item in the Kupperman Index, MENQOL total score, hot flush and sweating visual analogue scale (VAS), hot flush score, and hot flush duration at one time. However, there was also a significant change compared to baseline in the control group, there was no significant difference between the treatment group and the control group. There was no significant change in female hormone levels in both group, and there were no adverse events associated with the clinical trial product. Conclusions: This clinical trial showed that extract obtained from Pueraria thunbergiana Bentham and Curcuma longa L. was helpful in improving menopausal symptoms in menopausal women without significant side effects.
