  • Streptococcus mutans, Streptococcus sobrinus 등과 같은 구강 세균에 의해 생산되는 효소인 glucosyltransferase(GTase; sucrose 6-glucosyltransferase, EC 2.4.1.5) 는 충치 발생에 중요한 역할을 하는 것으로 알려져 있으며 Gtase-I, GTase-SI, GTase-S 등 최소 3종의 isozyme이 알려져 있다.$^{7-10)}$ GTase는 sucrose로부터 점착성이 있는 불용성의 glucan을 형성하고 이 glucan에서 구강 미생물이 증식하며 그 결과로 생성된 유기산에 의하여 치아표면의 에나벨 층이 부식되므로써 충치가 유발되게 된다.$^{11)}$ 따라서 불용성 glucan의 생성을 유도하는 GTase의 활성을 조절하는 것은 충치 발생 억제에 중요한 역할을 하는 것으로 판단된다. 본 연구자 등은 GTase를 효율적으로 저해하여 충치를 예방할 물질을 탐색하기 위한 연구의 일환으로 약 420종 식물체의 ethanol 추출물로부터 GTase 저해 활성을 검색하여 보고한 바 있다. 수종의 식물체 ethanol 추출물은 S. mutans에 대한 정균활성과 GTase 저해 활성을 동시에 나타내었으며 물질의 분리${\cdot}$정제로부터 oleic acid를 주성분으로 히는 불포화 지방산임이 밝혀진바 있다.$^{12)}$ 본 연구에서는 약 420종 식물체의 열수추출물을 대상으로 GTase 저해 활성을 검색하였다. 그 중 13종의 열수 추출물에서 비교적 높은 GTase 저해활성이 분포 되고 있음을 확인하였으며 활성이 높은 회향을 대상 식물체로 하였다. 회향의 열수 추출물은 S. mutans의 생육에는 영향을 미치지 않고 GTase 활성을 저해하는 특정을 가지고 있다(data not shown). 특히 사람을 대상으로 한 회향 열수 추출물에 의한 치면 세균막 억제 임상 실험 결과 plaque index의 저하를 가져오는 것으로 나타나 회향 열수 추출물은 GTase 활성을 저해하여 충치 예방 목적으로 적용 할 수 있음을 알 수 있다. 회향은 한국을 비롯한 아시아권에서 식품의 향신료 및 민간요법에 널리 사용되는 식물이고 식품의 원료로 사용할 수 있는 소재이다. 회향의 열수 추출물은 열에 대해 높은 안정성을 나타내는 가공 특성을 가지고 있으므로 천연물 기원의 충치예방 기능성 식품으로서의 산업적 이용가치가 기대된다.

  • Boiled-water extract (BWE) of Hizikia fusiformis has antioxidant effects. To investigate antioxidant effects of BWE, 1,1-dephenyl-2-picrylhydrazyl (DPPH) and thiobarbituric acid (TBA) methods were used. BWE exhibited strong radical-scavenging activity (87.3% at final conc. $2000\;{\mu}g$ BWE/ml in an assay mixture) on DPPH and good inhibitory activity (64% at final conc. $1000\;{\mu}g$ BWE/ml in an assay mixture) on lipid peroxidation. Raw 264.7 cells treated with lipopolysaccharide (LPS) showed 26.7-fold increase in nitric oxide (NO) ($48.9\;{\mu}M$) compared with control group ($1.83\;{\mu}M$). When treated with BWE and LPS, NO production was inhibited by BWE dose-dependently.

  • In the year of 1998 the heads of dog raised in Korea were 1,846,411 and the number of the households raising dogs is 819,112 which means that the heads of pet dog and edible dos were 819,112 and 1,027,299, respectively, because each house raised about one pet dog and one edible dog breeder raised hundreds of dog. in 1998 the number of exported dogs came to 28 heads and that of imported dogs was 296 heads. But edible dog that was slaughtered or processed has not been reported to be exported or imported. It is known that at the Shenyang Xingshan Food Ltd in Shenyang, Chinese, 300,000 heads of dogs were rais-ed slaughtered and processed of dog meat per year, and 20% of them were exported. In Korea the cook of dog meat is a special food culture with a long history. During the Chosun dynasty dog meat had been eaten to be cooked diversely such as Gaejangkuk(a soup) Suyuk(a boiled meat) Sundae(a sausage) Kui(a roasted meat) Gaezim(a steamed meat) Nurumi(a meat roasted or fried to which lot of spice paste are added) Gaesoju(an extract) Musulju(a wine) Musuldang(a sweet cane) Now it is cooked as Bosintang(a soup) Suyuk (a boiled meat) Jeongol (boiled meat mixed with spices vegetables and water on the pot) Duruchigi(boiled meat added spice vegatasble and slightly roasted) Muchim(boiled meat added by spice and mixed) Gaesoju(an extract) with the number of recipes lessened compared with those of the old times. The reason is due to the intervention and criticism from foreign countries. But foreigner's blame for the dog meat is absurd and excessive action because Korea raises exceptional dogs which are edible.

  • This study was conducted to evaluate the antioxidative and anti-inflammatory effects of boiled pork powder (BPP) and hot water extract powder (HWEP) from 4 cuts of meat from Landrace × Yorkshire × Duroc (LYD). The highest DPPH radical scavenging activities determined were from BPP of Boston butt (13.65 M TE) and HWEP of loin (19.40 M TE) and ham (21.45 M TE). The 2,2-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activities of BPP from shoulder ham (39.28 M TE) and ham (39.43 M TE) were higher than those of other meat cuts, while HWEP of ham exhibited the highest ABTS radical scavenging activity. A higher oxygen radical absorbance capacity was determined for BPP from ham (198.35 M TE) and in HWEP from loin (204.07 M TE), Boston butt (192.85 M TE), and ham (201.36 M TE). Carnosine content of BPP and HWEP from loin and were determined to be 106.68 and 117.77 mg/g on a dry basis, respectively. The anserine content of BPP (5.26 mg/g, dry basis) and HWEP (6.79 mg/g, dry basis) of shoulder ham exhibited the highest value as compared to the extracts from the other meat cuts. The viability of RAW 264.7 cells was increased with increasing HWEP from loin and ham treatment. In addition, the expression of IL-6 and TNF-α was significantly reduced by HWEP from loin and ham, in a dose dependent manner. These results suggested that boiled pork and hot water extract of pork have antioxidative and cytokine inhibitory effects.

『소아약증직결(小兒藥證直訣)』에 기재된 처방 복용법 중 금은화박하탕하(金銀花薄荷湯下) 구절에 대한 고찰 (A study on the Jinyinbohetangxia verse of the medication instructions in the Xioaeryaozhengzhijue)

  • Objectives : This study aims to clarify the interpretation of the verse "jinyinhuabohetangxia(金銀花薄荷湯下)" in Zhouxuehai(周學海)'s corrective commentary in the Xiaoeryaozhenzhijue(小兒藥證直訣), by examining traditional pediatric texts in relation to the verse. Methods : For each of the three possible interpretations of the instructive phrase for taking herbal formulas-Lonicera flower with peppermint(金銀花+薄荷), gold and silver with peppermint(金銀+薄荷), and gold coin peppermint(金錢薄荷)-applications of these herbs in the various pediatric books were analyzed to determine the most appropriate interpretation. Results & Conclusions : The formulary composition of Liangjingwan(凉驚丸) and Wusewan(五色丸) seems to sufficiently target the pathology of pediatric convulsion(驚癎) and heart malnutrition(心疳). Furthermore, it seems unnecessary to add Lonicera flower(金銀花) to the gastrointestinal fragility(脾胃虛弱) of the malnourished(疳). Some of the herbal formulas in the pediatrics chapter of the Zhengzhizhunsheng(證治准繩) include Lonicera flower(金銀花) to treat only carbuncles(癰腫, 腫毒), while other books do not include it in their formulas. On the other hand, instructions to take water boiled with gold and silver appear in many texts, including the Xiaoeryaozhenzhijue(小兒藥證直訣), and sometimes include gold leaf(金箔) directly in the formula. Descriptions of gold and silver pots with instructions on how to make herbal formulas were found as well, which supports what Zhouxuehai(周學海) commented on the Xiaoeryaozhenzhijue(小兒藥證直訣). Although gold coin peppermint(金錢薄荷) is currently used as Lianqiancao(連錢草) in China, it was difficult to verify its identity as Jinqianbohe(金錢薄荷), which seems to have been recognized as a type of mint in the past. No reported anticonvulsant studies of Lonicera flower(金銀花), gold and silver(金銀), and Lianqiancao(連錢草) were found. Peppermint(薄荷) was ubiquitous in instructions for taking herbal formulas treating pediatric convulsions. Therefore, the instruction to take water boiled with gold and silver, or to take the herbal medicine in water boiled in a gold and silver pot, rather than using Lonicera flower(金銀花), could be considered as an interpretation closer to the original author's intent.

  • Among all the ingredients usedin mandu, the following types were used:, 13 types of grains were used (12.38%), 30 types of vegetables, fruits, bulbs,and nuts were used (28.57%), 32 types of marine products, birds, meats, fishes, and shellfishes were used (30.48%), 10 types of functional ingredients were used (9.52%) and. For spices, 20 types of spices were used (19.05%). 2. Cooking Methods offor Mandu. The mMandu eaten at in the early Joseon era had was primarily made ofusedbuckwheat that contained boiled tofu or egg uiijuk in the kneaded dough for the most part and while kneading with buckwheat, the tofu or egg uiijuk has been boiled down to knead the dough, and and starch powder, bean powder, or rice powder, etc were mixed to make the mandu coating. Buckwheat powder was mixed toadded to the flourwer or was used by itself, while meat, vegetables, tofu, and shiitake mushroom, etc were also addedincluded. From the 18th century, the host plant, or cabbage kimchi, were prepared and combined had been sliced to be used as filling together while red pepper powder was mixed combined withto spices or vinegar soy sauce to be used together. Also, Radishes had beenwere also used as filling, but shown as not being used fromafter the start of the 1900's. For the shape of mMandu, it was madeinto different shapes such as as triangle, rectangle, date plum, gwebul, half moon, or pomegranate shapes, and then shapes to be boiled in simmering water, baked, or cooked as soup in clear broth for soup., In the 17th to 18th century, boilingthen in a steamer gradually became a cooking style, assumed the style of boiling in a steamer in $17th{\sim}18th$ century while in the 16th century,the an essay ofn fermenting flour in ‘Food Dimibang’ in 16th century had indicated it was cooked as the style ofby steaming in a rice steamer. Also, Mandu may have also contained the following: the thin-cut and boiled fish was cut out thin to put into the filling and boiled down, made by putting in added pine nuts after making bbeef jerky or boiled- down meat, fish, or shellfish itself to extractsand mold mandu only the ingredients combined withto put on starch powder, and then boiled down and put on pine nut powder finally, after it or cooled it wasdown to be eaten by dipping in vinegar soy sauce. In conclusion, many different types of mandu were made during the Joseon era using a variety ofwhile the ones using such various ingredients. are also one type of mandu.

  • This study was carried out in order to estimate the residual amount of mercury in soy-bean sprouts in each steps of cooking. Samples were taken at markets and also cultured at home without applying the mercury containing pesticides as control. Mercury was determined by dithizone method. It was disclosed that soy-bean sprouts purchased at markets contained $1.32{\pm}0.274ppm$, 13 times as high as the maximal allowable concentration of mercury in food recommeded by Ministry of Health and Social Affairs. Mercury contents, however, dropped off steadily by steps of cooking: rinsed with distilled water and boiled in distilled water showing concentrations of $0.11{\pm}0.025ppm$ in boiled sprouts and $0.03{\pm}0.022ppm$ in sprout-soup. These values were not statistically different from those in control samples, and not exceeded the maximal allowabled levels of mercury in food. It can be concluded that the use of mercury containing pesticides in the cultivation of soy-bean sprouts is not so serious problem as it has been suspected in respect of food contamination, but careful attention must be paid to indiscriminate use of mercury containing pesticides as they may contaminate air, water and soil and secondarily bring harm to human health through food chains.

  • The purpose of this study was to examine the effect of heat generated by rotating bur on the dental hard tissue in vitro. Freshly extracted molar teeth with normal appearance from early 20's male were collected and experimental teeth were divided into 4 groups and the teeth in each group were prepared class I cavity with different clinical procedures as follows. The four methods were. I. 20,000rpm without coolant II. 20,000rpm with coolant III. 500,000rpm without coolant IV. 500,000rpm with coolant Five teeth were reserved intact as a control group. These teeth were longitudinally split into two parts by means of chisel after class I cavity preparation. In a control group 5 parts were boiled in water for 20 minutes and the other 5 specimens were not boiled. All specimens were immersed in 2% methylene blue dye solution and the image of dye penetration was examined and photographed under stereomicroscope. Followings were the results obtained through the study. 1. In control group, dye penetration of the unboiled specimens was increased than with the boiled group. 2. The specimens prepared cavity without coolant showed decreased dye penetration than with the coolant group. 3. 20,000rpm without coolant group showed the least dye penetration. 4. 500,000rpm with coolant group showed similar level of dye penetration to the unboiled specimens from the control group.
