  • 목적 ; 본 연구는 가스분석검사기의 일종인 Oral $Chroma^{(R)}$(CHM-1, Osaka, Japen)를 이용하여 건강검진센터에 내원하는 환자를 대상으로 전신질환 판정검사에서 이상소견을 가진 환자에서 구취를 일으키는 휘발성 황화합물을 측정 비교하여 전신질환이 구취에 미치는 영향을 알아보고자 하였다. 방법 ; 수집된 자료는 통계분석 프로그램인 Statistical Package for the Social Science12.0(SPSS Inc, Chicago, IL, USA)을 이용하여 구강검사(CPI index, 탐침 시 출혈 유무, 설태의 유무) 결과 및 각 검사별 전신질환의 유무에 따른 황화수소, 메틸 머캅탄, 황화 디메틸의 농도를 교차분석으로 분석하였다. 결과 ; 휘발성 황화합물과 관계있는 질환은 간질환과 담낭질환이라는 사실을 확인할 수 있었으며 그 외 골밀도와 혈압, 지질검사 등에서의 관련성도 관찰되어 추후 연구가 더 필요할 것으로 생각된다.

  • Purpose: Salivation is considered to be an important factor in the control of halitosis, and the amount of salivation has been shown to be closely related to the level of hydration. The purpose of our study was to evaluate the relationship between dehydration and halitosis. Methods: Twenty healthy young females with no dental problems were recruited. All participants were induced to become dehydrated and then over-hydrated. After inducing each hydration state, the severity of hydration and halitosis factor (organoleptic scores, amounts of resting and functional saliva, gas examinations, and tongue coatings) were measured. Hydration statuses were graded as dehydration, normal, or over-hydration according to urine osmolality. This was a cross sectional study with a cross over design. Results: The dehydrated status was associated with higher organoleptic scores than the normal or over-hydrated status (1.75±0.75 vs. 0.87±0.63, and 0.65±0.53, respectively. p<0.05). Mean values of CH3SH, (CH3)2S in portable gas chromatography for the dehydrated, normal, and over-hydrated status were 11.70±37.00, 6.75±13.50, and 2.80±5.87 nmol/mol, 10.50±15.59, 7.25±10.87, and 1.50±2.55 nmol/mol, respectively. p>0.05). (CH3)2S (r=0.410, p=0.009) showed a moderate positive correlation with dehydration status. The resting salivation rates were relatively lower for the dehydrated status than for the normal or overhydrated status (p>0.05), and tongue coating results were also higher for the dehydrated status (p>0.05). Conclusions: Dehydration status appears to be positively correlated with a low resting salivation rate and high portable gas chromatography results. This shows that dehydration might be an etiologic factor of halitosis.

  • 신경계 질환은 산화적 스트레스에 의한 신경세포 손상에 의해 발생하는 것이 하나의 기전으로 알려져 있다. 본 연구는 $H_2O_2$에 의해 유도된 산화적 스트레스에 대항하여 곤드레(Cirsium setidens, CS), 누룩치(Pleurospermum kamtschaticumin, PK) 그리고 산마늘(Allium victorials, AV)의 뇌신경 보호 효과 및 그 기전에 대한 것이다. CS와 AV 처리는 대조군과 비교하여 $400{\mu}g/mL$까지 인간의 신경세포주인 SK-N-SH 세포에 대해 세포독성이 없었다. 산화적 유도자인 $H_2O_2$를 SK-N-SH 세포에 처리하였을 때 세포사멸 및 활성산소종(ROS) 생산이 현저하게 증가하였으나 CS 또는 AV 처리에 의해 산화적 스트레스에 의해 증가된 세포사멸과 ROS 생산이 현저하게 감소하였다. 실험한 산채 중에 CS와 PK가 AV보다 더 강한 DPPH 라디칼 소거 작용이 있었으나 PK는 대조군과 비교하여 SK-N-SH 세포를 사멸시키는 강한 세포독성을 가지고 있었다. CS는 AV보다 산화적 스트레스에 대항하여 세포사멸 및 ROS 생성에 더 높은 저해적 영향력을 보여주었다. 따라서 계속되는 실험에는 CS를 사용하였다. CS의 순차적 용매 분획물들인 헥산, 클로로포름, 에틸아세테이트, 부탄올 및 물 분획물들(CS-HE, CS-CH, CS-EA, CS-BU, CS-AQ)은 산화적 스트레스에 대항하여 SK-N-SH 세포사멸 및 세포내 ROS 생성을 억제하였다. CS-EA는 5개의 분획물들 중 가장 강한 DPPH 라디칼 소거작용 및 세포내 ROS 소거 활성을 가지고 있었고, 가장 강한 뇌신경세포 보호 효과를 가지고 있었다. CS-EA는 산화적 스트레스에 의해 증가된 세포자멸사(apoptosis)의 신호전달 경로에 관여하는 p38의 인산화를 저해함으로써 활성화되는 것을 약화시켰다. 이 결과들은 CS-EA가 뇌신경세포에서 항산화 효과 및 p38 인산화 억제에 의한 뇌신경 보호 효과를 나타낼 것이라 제안하였다.

  • The supported bimetallic Co-containing catalysts promoted by the different amount of noble metal (Pd) have been studied in the dry reforming of methane. The activity, selectivity, stability and resistance to the carbon deposition of Co-Pd/$Al_2O_3$ catalysts depend on both the catalyst composition and process conditions. It has been observed that the Co-Pd/$Al_2O_3$ catalysts produce the various oxygenates from $CO_2$ + $CH_4$ at moderate pressures.

  • This paper studies women's clothing and textiles recorded in the『the Odes』, and refers research materials on the old commentaries about the『the Odes』and the various kinds of records and remains. The results regarding women's clothing in『the Odes』are follow: 1. Ti-i, Chin-i are the women's ceremonial dresses. Ti-i is a kind of the court dress and the shape is a long dress embroidered with pheasant. Chan-i belongs to the lower grade compared with the six ritual dresses worn by the queen and is made of Hu that is a kind of the white soft-wrinkled fabrics. 2. A women's I-Shang is composed of a blouse and a skirt. It is the classic style before the Sh n-I appears in China. Also we find that they use the standard colours for a blouse and the intermediate colours for a skirt in Chou period. 3. Chiung-I, Chiung-Shang and Hsieh-Pen are a kind of the robe put over the former garment made of Chin not to display to elegance. 4. Fu, Ch n-Fa, Pei and T'i are a kind of women's wig. Ti and the six-Chia are women's hair ornaments. Ch'i-Chin and Ju-L are a kind of the working women's turbun. 5. The women's belt ornaments are classified into the practical things and the decorational things like those for men. The results regarding fabrics in the『the Odes』are as follow: 1. The silk fabrics; There are Chin, Hu, Chou, Tz , Su, Hsiu. 2. The woolen fabrics; There is Ho. 3. The linen fabrics; There are the hemp and the ramie in the remains of Chou period. Also there are Ch'ih and Hsi categorized in Ko fabrics.

  • Objective: The aim of this prospective, case-controlled study was to assess the difference of the amount of tongue coating between halitosis and non-halitosis patients using a digital tongue diagnosis system (DTDS). Methods: Sixty-five patients complaining of oral malodor were recruited for the study. The level of volatile sulfur compounds (VSC) in the oral cavity of the patients was measured by a portable gas chromatography. All patients were then divided into two groups, the halitosis group ($H_2S{\geq}1.5ng$/10ml, or $CH_3SH{\geq}0.5ng$/10ml) and the non-halitosis group ($H_2S$<1.5ng/10ml and $CH_3SH$<0.5ng/10ml), according to the VSC level criteria published by Tonzetich. Tongue images of the two groups were acquired and analyzed by DTDS, followed by the analysis of the tongue coating scores. Results: The tongue coating scores of the halitosis group were significantly higher than of the non-halitosis group (P=0.033). Furthermore, the difference of the posterior tongue coating between the two groups was more significant (P=0.000). Conclusions: Halitosis patients were shown to have a thicker tongue coating than those in the non-halitosis group. Moreover, the posterior dorsum of the tongue should be observed more cautiously when dealing with halitosis patients. Also, the progress and state of the patient's symptom of halitosis as diagnosed objectively by the portable gas chromatography could also possibly be analyzed instead by the DTDS tongue coating score.

  • 본 연구는 을지대학교 치위생학과에 방문한 스케일링 환자 155명을 대상으로 구취와 구강건조감, 스트레스의 관련성을 파악하여 효율적인 구취관리를 위한 기초자료로 제공하고자 실시하였다. 분석은 PASW Statistics 18.0을 이용하였으며, 다음과 같은 결론을 얻었다. 일반적 특성에 따른 구취 측정 결과는 $H_2S$의 경우 연령에 따라 유의한 차이가 있었으며, 20대가 355.61로 가장 높았고, 다음 50대가 227.85였다(p<0.001). $CH_3SH$가 축농증, 비염이 있는 경우 높게 나타났다(p=0.034). 구취성분 간의 상관관계는 $H_2S$$(CH_3)_2S$가 관련성을 보였으며(r=0.492, p<0.01), 구취에 영향을 미치는 요인으로는 스트레스가 증가할수록 $(CH_3)_2S$가 증가하는 것으로 나타났다. 이상의 결과 구취를 호소하는 환자 진단 시 스트레스와 같은 정서적 요인 조사에 좀 더 관심을 가지고 고려해야 할 필요가 있다고 생각되며, 체계적이고 표준화된 진단 도구 개발에 노력해야 할 것이다.

  • The preparations of deodorizing fibers using medal-phthalocyanines have been investigated. The five metal-phthalocyanine derivatives(M-taPc, M=Fe, Co, Ni, Zn, Cu) were prepared in modest to good yields. The metal-phthalocyanine derivative as a deodorant material was introduced to fibers by a dyeing method. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. In comparison with untreated fibers, these deodorizing fibers was remarkably effective against $NH_3$ and CH3SH. More than 99% of ammonia can be removed within 20 min. The D.A.(%) of fiber adsorbed M-taPc was more than 80% after 90min.
