The purpose of this study was to investigate antioxidative and nitrite scavenging abilities of extracts of medicinal plants. Three kinds of medicinal plants, Angelica acutiloba Kitagawa (AA), Akebia quinate Decaisne (AQ), and Caragana chamlagu (CC), were extracted with water and $70\%$ ethanol. The yields of water extracts were increased in the order of Akebia quinate Decaisne ($35.63\%$, Caragana chamlagu ($31.36\%$ and Angelica acutiloba ($8.98\%$). Those of ethanol extracts were Akebia quinate Decaisne ($31.82\%$, Angelica acutiloba Kitagawa ($14.15\%$, and Caragana chamlagu ($5.20\%$). The highest electron donating ability (EDA) at 300-1,000 ppm of water extract was Angelica acutiloba Kitagawa, ranged from $62\%$ to $88\%$ and that of ethanol extract was Akebia quinate Decaisne, ranged from $72\%$ to $87\%$. Nitrite scavenging ability (NSA) of extracts measured at various pH (1.2, 3.0, 4.2, 6.0) showed highest ability in all extracts at pH 1.2 and decreased with increasing pH. The highest NSA of water extracts of 1,000 ppm at pH 1.2 showed $35-40\%$, in Caragana chamlagu and that of ethanol extract was $33-42\%$, in Akebia quinate Decaisne. From these results, Akebia quinate Decaisne was found as a potential raw material baring functionality in the respects of extract yield, EDA and NSA.

Background: this study examined the Chiropractic therpy's influences on range of motions and pains with patients who have neck pain. Methods: In an experimental study with a two-group(chronic neck pain vs acute neck pain) design, 16 participants were enrolled for 2 weeks, 4 times, from march to april, 2013, with 8 acute neck pain patients and 8 chronic neck pain patients in chiropractic threrapy. Results: after the chiropractic threrapy, range of motions improved and pains were reduced significantly in both acute and chronic neck pain patients(P<.05). Conclusion: the chiropractic threrapy was effective in improving range of motions and reducing pains in persons who have acute and chronic neck pain. Thus, the chiropractic threrapy could be a resource for continuing study and adaptations to enhance the quality of life and well-being of neck pain patients.

This paper describes experimental results on the utilization of some Korean oak woods for whisky aging barrel. Some anatomical characteristics as vessel diameter, ray spacing, ray height, existence of tyloses, water absorption and color change of alcohol during immersing of wood samples were examined. The oak woods used in this study were ring-porous. The type of ray was a compound ray consisted of uniseriate ray and broad ray. The ray parenchyma cells were almost procumbent, tyloses were presented in white oak(Quercus aliena, Quercus variabilis, Quercus dentata, Quercus mongolica), but absented in red oak(Quercus rubura). Density of wood samples decreased during immersing in alcohol. Alcohol color in Quercus dentata and Quercus aliena presented more darker than other samples. Water absorption of sapwoods was higher than that of heartwoods. Especially, red oak showed more higher water absorption than white oak. Consequently, Korean white oak woods can be used as the whisky aging barrel.

Treatment for heart failure is directed to reduce atrial volume overload by diuretic agents, to lessen ventricular pressure overload by vasodilatory agents and to increase myocardial performance through inotropic agents. Of those cardiac therapeutics, diuretic agents are the most important to control heart failure in dogs, although long-term use often causes detrimental side-effects such as acute renal failure and electrolyte abnormalities. Thus, this study was designed to find a new diuretic agent from medicinal herbs which has better diuretic effect and less unfavorable complications in dogs. In a preliminary study performed with 5 normal healthy dogs, the extract from Akebia quinata Decaisne showed mild to moderate diuretic effect (0.3-0.5 potency of furosemide 2 mg/kg) and minimal changes in serum chemistry and electrolyte. Although the study population was not large enough and study period was not sufficient enough, this study found a good alternative diuretic agent which can replace or reduce the use of furosemide in dogs with heart failure.

Aristolochic acid has been known to be a carcinogenic compound and to cause Chinese herbs nephrophathy(CHN). To determine the content of aristolochic acid in various medicinal herbs marketed domestically, samples of Aristolochia fangchi, Aristolochia fructus, Aristolochia radix, Asiasari radix, Saussureae radix, and Akebia caulis were analyzed using TLC and HPLC. The optimal conditions for TLC and HPLC using $C_{18}$ column were established for the quantitative analysis of aristolochic acid. This study showed that Aristolochia fangchi and Aristolochia fructus examined in this study contain aristolochic acid of 3.9 and 2.3 mg/g sample, respectively. In contrast, aristolochic acid was not detected in the other samples.

약용식물의 추출물을 식품 제조시에 첨가제로 사용할 목적으로 4종류의 약용식물을 추출하여 각 식물의 기능성을 조사하였다. 골담초, 당귀, 목통, 초피의 나무 줄기를 물과 70% 에탄올로서 추출하여 동결 건조한 후 항균작용, 항산화작용 및 아질산염소거능을 조사하였다. 각 시료의 물과 에탄올추출물의 식중독세균에 대한 항균작용은 그람음성균인 Escherichia coli, Salmonella typhimurium, Shigella sonnei에 대하여 억제 작용을 나타내지 않았다. 그러나 골담초와 당귀의 에탄을 추출물은 2％ 이상의 농도에서 그람양성균인 Listeria monocytogenes와 Staphylococcus aureus의 증식을 억제하였다. 각 시료 물추출물의 전자공여능은 500ppm이상의 농도에서 모두 60% 이상의 전자공여능을 나타내었다. 각 시료의 에탄을 추출물은 목통과 초피가 300ppm에서 70% 이상의 전자공여능으로 물추출물보다 우수하였고 골담초는 물추출물과 비슷한 수준이었으며 당귀는 물추출물보다 낮은 전자공여능을 나타내었다. 각 시료 추출물의 아질산염소거능은 물추출 1,000ppm, pH 1.2에서 당귀 38%, 골담초 40%, 목통35%의 소거능을 나타내었으며 초피가 50%로서 가장 우수한 아질산염소거능을 나타내었다. 각 시료에탄을 추출물의 아질산염소거능은 당귀와 골담초가 물추출물보다 약간 낮은 소거능을 나타낸 반면에 목통과 초피는 물추출물보다 높은 아질산염소거능을 나타내었는데, 특히 초피는 1,000ppm pH 1.2에서 66%의 우수한 아질산염소거능을 나타내었다.

We investigated the effects of heat treatment and extraction method on the antioxidant activities of five medicinal plants: Cyperus rotundus, Eucommia ulmoides, Bupleurum falcatum, Achyranthes japonica Nakai, and Akebia quinata. Extraction was performed with only ultrasound, ultrasound after heating at $130^{\circ}C$ for 2 hours, and reflux extraction with distilled water. The phenolic contents of reflux extraction and ultrasound extraction after heating were higher than only ultrasound extraction, and ultrasound extraction after heating samples was higher than reflux extraction except for Eucommia ulmoides and Cyperus rotundus. Total flavonoid content was higher in reflux and ultrasound extraction after heating samples than only ultrasound extraction, except for Cyperus rotundus. ABTS radical scavenging activity was higher in reflux extraction and ultrasound extraction after heating a sample, than only ultrasound extraction. DPPH radical scavenging activity was higher in reflux extraction except for Achyranthes japonica Nakai and Akebia quinata. The reducing power of ultrasound extraction after heating was higher with Achyranthes japonica Nakai. From the results of this study, we can expect to increase the antioxidant activity of medicinal plant extracts by applying suitable extraction and pretreatment conditions on the type of medicinal plant.

Antimicrobal effects of Akebia quinata DECAISNE were studied. Their Stems and Fruits were extracted with ethanol and water. The ethanol extracts, boiling ethanol extracts, boiling water extracts were not showed the inhibitory effects. But water extracts of stems and fruits were showed inhibitory effects on the 2species.(Bacillus subtills KCTC 1021, Bacillus cereus KCTC 1012)
