본 연구에서는 채소류의 표면에 인위적으로 균을 오염시킨 후 수도수, 마이크로버블수, 전기분해수 및 마이크로버블-전기분해수 세척에 의한 미생물 살균 효과를 알아보았다. 우선 수도수와 마이크로버블수 세척에 의한 살균 효과를 비교한 결과, 수도수와 마이크로 버블수 사이에 살균력 차이는 미세하게 마이크로버블수가 높게 나타났다. 유효 염소 농도별 전기분해수와 마이크로버블-전기분해수 세척에 의한 살균 효과를 비교한 결과, 유효염소 농도가 100 mg/L인 전기분해수는 5분간 세척 후 채소류의 종류에 따라 미생물이 잔존하였지만, 100 mg/L인 마이크로버블-전기분해수는 5분간 세척 후 모든 채소류에서 균이 검출되지 않았고, 200 mg/L인 마이크로버블-전기분해수에서는 1분간 세척 후에 모든 채소류에 미생물이 검출되지 않았다. 따라서 각 유효 염소 농도별 마이크로버블-전기분해수가 전기분해수에 비해 짧은 세척시간에 효과적인 살균이 된 것으로 나타났다. 종합적으로 마이크로버블-전기분해수 세척 기술이 미생물학적 위험은 감소시키면서 표면 살균 효과가 낮은 채소류와 같은 신선편의 식품에 적합한 살균 기술로 생각된다.

Background: The main goal of this study was to evaluate the diagnostic efficacy of reverse transcription-nested polymerase chain reaction (RT-nested PCR) in bronchial washing fluid with MAGE A1-6 common primers for the detection of lung cancers invisible by bronchoscopy. Methods: To determine the expression of MAGE A1-6 gene in 189 lung cancers diagnosed by conventional fluoroscopy-guided lung biopsy and 89 cancer-free controls, RT-nested PCR was performed in bronchial washing specimens. We analyzed MAGE A1-6 RT-nested PCR data according to tumor histology, stage, size, and compared them with cytological data. Results: 189 patients (111 cases in adenocarcinoma, 47 cases in squamous cell carcinoma, 22 cases in small cell lung carcinoma, and 9 cases in other cancers) and 89 benign patients were investigated. The expression of MAGE was performed by nested RT-PCR using common MAGE primer. Among 189 cancer patients, the expression rate of MAGE was 49.2%, and the positive predictive value was 89.4%. However, the expression rate of MAGE in patients with benign lesions was 12.4%. In peripheral lung cancer, the positive rate of MAGE expression was 57.4% in squamous cell carcinoma, 44.1% in adenocarcinoma and 59.1% in small cell lung cancer. Whereas the expression rate of bronchial washing cytology in peripheral lung cancer was 9.0% (p=0.011). Conclusion: MAGE RT-PCR in bronchial washing fluid gave us promising data for the detection of peripheral lung cancer. It could be a useful method for selecting diagnostic tools for peripheral lesions.

A pre-treatment process has been developed for natural dyeing of wool by which the dyed materials have been imparted antimicrobial efficacy against both gram-positive and gram-negative bacteria durable up to 20 washes. In this process, wool fabrics were treated with citric acid under oxidizing condition prior to dyeing. The treated fabrics were then dyed with four different types of natural dye powders obtained from leaves of silver oak, wattle, tanner's senna and flame of forest. All the natural dyes produced yellowish brown colour on wool fabrics. The washing and light fastness properties of the fabrics subjected to pre-treatment were one grade higher compared to those of the dyed fabrics without pre-treatment. The pre-treated wool fabrics showed antimicrobial efficacy against both gram-positive bacteria (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli). The fabrics dyed without pre-treatment showed antimicrobial efficacy against gram-positive bacteria (Staphylococcus aureus) only. The durability of antimicrobial efficacy was higher in pre-treated and dyed wool fabrics compared to the dyed fabrics without pre-treatment.

Purpose: The role of peritoneal washing cytology in determining further treatment strategies after surgery for gastric cancer remains unclear. One reason for this is the fact that optimal procedures to increase the accuracy of predicting peritoneal metastasis have not been established. The aim of this study was to evaluate the efficacy of cytology using samples harvested from two different abdominal cavity sites during gastric cancer surgery. Materials and Methods: We prospectively recruited 108 patients who were clinically diagnosed with locally advanced gastric cancer (higher than cT1 stage disease). Peritoneal washing fluids were collected from the pouch of Douglas and the subphrenic area. Patients were prospectively followed up for 2 years to determine the recurrence and survival rates. Results: Thirty-three patients dropped out of the study for various reasons, so 75 patients were included in the final analysis. Seven patients (9.3%) showed positive cytology findings, of whom, three showed peritoneal recurrence. Tumor size was the only factor associated with positive cytology findings (P=0.037). The accuracy and specificity of cytology for predicting peritoneal recurrence were 90.1% and 94.2%, respectively, whereas the sensitivity was 50.0%. The survival rate did not differ between patients with positive cytology findings and those with negative cytology findings (P=0.081). Conclusions: Peritoneal washing cytology using samples harvested from two different sites in the abdominal cavity was not able to predict peritoneal recurrence or survival in gastric cancer patients. Further studies will be required to determine whether peritoneal washing cytology during gastric cancer surgery is a meaningful procedure.

The objective of this study is to investigate the efficacy of pomegranate hull colorant as a natural hair coloring dye. The extract of pomegranate hull was concentrated and freeze-dried to get colorant powder. Effect of dyeing condition and mordanting on the dye uptake of hair by using Al, Fe, Cu, Cr, Sn compounds, color change and colorfastness were explored. In addition, tensile strength was measured and the surface of the hair was observed. Dye uptake of hair measured by K/S value (400 nm) indicated that ionic bonding seems to be involved in the sorption of pomegranate colorant to hair. Maximum sorption was obtained at pH 3.5 and the concentration of 50% (on the weight of hair, o.w.h.). Acidic dyeing condition (pH $3.5{\sim}5.0$) showed yellow color however alkaline dyeing condition (pH $7{\sim}11$) gave reddish yellow color. Pomegranate hull colorant produced greyish brown color on hair and the hair mordanted with Fe showed dark brown color. Mordants except Fe did not increase dye uptake significantly. Mordants except Cu increased light fastness and mordants except Cr increased washing fastness level slightly. According to SEM observation and the tensile strength retention measurement, the mordant dyed hair gave more damage to hair by ultraviolet light and washing than the hair dyed without mordanting. Experimental results of K/S value and colorfastness(light and washing) supported that pomegranate hull colorant without mordanting can be used as a semi-permanent natural hair coloring dye.

The purpose of this study is to investigate the efficacy of safflower yellow colorant as a natural dye for hair coloring. The dyeing properties of safflower yellow colorant on hair were explored to obtain optimum conditions. Also, the effect of mordant was studied in terms of dye uptake, colorfastness, and hair damage to better understand the characteristics of the colorant. Tensile strength measurement and SEM analysis were carried out for investigating hair damage to light exposure and washing. On the basis of obtained results considering possible hair damage, optimum dyeing conditions were set 100%(o.w.h.) colorant concentration, pH 5, $40^{\circ}C$, and 20min. Dye uptake was improved more effectively by repeated dyeing rather than by increasing concentration. Pre-mordanting method improved dye uptake slightly, irrespective of mordant type. The safflower yellow colorant produced Y colors on hair. Cu and Fe mordants improved washing and light fastness slightly. Better strength retention was obtained with the mordanted-dyed hair than the unmordanted-dyed hair after light irradiation for 40 hours and 10 repeated washing. The hair was more damaged by light exposure than by washing. It was concluded that the safflower yellow colorant can be used as a natural semi-permanent hair dye producing Y color without mordanting.

본 연구는 식중독을 일으키는 병원성 미생물들은 식품시료와 교차오염 원인의 지표가 될 수 있는 도마에 접종한 후 오존수와 일반 수돗물을 이용하여 세척한 후 미생물의 변화와 세척방법에 따른미생물의 변화를 각각 비교 관찰하였다. 실험결과 일반 수돗물보다 오존수가 살균효과가 더 높았고, 같은 세척수로 세척 시에도 접종 방법, 실험시료 및 시료의 표면, 균질화에 따라 살균효과가 다르게 나타나는 것을 확인할 수 있었다. 세척방법으로는 침수보다 주수 에서 살균효과가 더 컸으며 오존수의 농도는 0.2 ppm에서 유의적인 살균효과를 나타내었으며 오존수 농도가 0.4, 0.6, 1.0 ppm으로 증가함에 따라 농도 의존적으로 살균효과 또한 증가하였다. 위의 결과들을 통해 0.2 ppm 이상의 오존수가 부패 미생물 제어에 미치는 영향이 크고 식품의 제조 가공 시 여러 안전성 면에 있어서 오존수를 이용한 세척이 효과적이라고 생각된다.
