In this study, we used a chemiluminescence reaction to investigate the removal effect of pet soil, such as dog blood, urine and feces. The soiled fabrics were washed with a standard laundry course of 30℃ and a washing time of 30 min and a pet care laundry course of 40-60℃ and a washing time of 100 min. The detergency was evaluated by the surface reflectance and chemiluminescence reaction (bloodstain detection by luminol test and urine-stain and feces-stain detection by UV blacklight test) before and after washing. The surface reflectance results did not show any difference in detergency for both courses, whereas the chemiluminescence reaction did. The detergency of the pet care course compared to the standard course was 101% according to the surface reflectance and 120% according to the chemiluminescence reaction. Therefore, residual stains not detected by surface reflectance can be evaluated through chemiluminescence reaction, and it was confirmed that pet stains can be managed more hygienically by washing for a long time at a high temperature.

축산용 항생제는 투여된 양의 일부만이 체내에서 사용되며 나머지는 모화합물 형태나 대사체로서 분뇨를 통하여 배출된다. 이러한 분뇨는 자원화 시설로부터 퇴액비로 생산되어 농경지에 살포됨으로써 농업환경에 유입되어 2차 오염 등을 초래하고 있다. 본 연구는 국내 가축분뇨 자원화 시설의 액비 생산단계별로 6종 축산용 항생제의 잔류 농도를 비교하고 액비 성분 질소 함량과의 상관성을 평가하기 위해 수행되었다. Buffer 및 SPE를 사용한 전처리 방법은 ppb 수준에서 63.4-106.7%의 회수율을 나타냈으며, 정량한계의 범위는 0.009-0.037 ㎍/L이었다. 공동자원화 시설 생산 액비의 생산단계별 잔류 항생제 농도와 규격함량 N 성분 함량과의 상관성 평가를 분석한 결과 액비화 과정 중 부숙 기간이 경과함에 따라 N 성분 및 항생제 잔류 농도가 감소하는 경향을 보여 주었다. 액비 원료, 중기 및 제품 중 SMZ의 평균 잔류 항생제는 40.85, 26.17, 3.54 ㎍/L이었으며 CTC의 경우 2.32에서 1.25 ㎍/L 수준으로 감소하였다. 다른 4종 항생제 역시 생산단계별로 잔류 농도가 감소하는 경향을 보여주었으며 액비 규격성분 N은 생산단계별 함량이 0.21에서 0.096%로 감소하였다. 액비 생산단계별 잔류 항생제 농도와 규격 성분 N 함량과의 상관성 평가는 항생제 저감화 지표 설정의 기초자료로 활용 가능할 것으로 판단된다.

Introduction The purpose of this study was to systematically review previous studies on Sasang type-specific pathophysiological symptoms in urination and defecation. Methods Peer-reviewed articles on type-specific pathophysiological symptoms of urination and defecation published until September 2016 were extracted from domestic and international six databases. Clinical characteristics from thirteen extracted articles were categorized into three urination domains of appearance of urine, capacity of bladder and urinary discomfort, and three defecation domains of irritability of bowel movement, functional constipation and discomfort from irregularity. Results As for the urination, Tae-Eum type showed dark color with foam, however So-Eum type had frequent urination and sensitivity to dysuria but no nocturia and residual urine sense. As for the defecation, So-Yang type showed frequent urgency and constipation, however So-Eum type reported loose stool. So-Yang type showed varied level of health status depending on defecation irregularity. There were disparities with rectal tenesmus among Sasang types. Discussion Six domains of urination and defecation related type-specific pathophysiological clinical symptoms were provided in this study. This study would contribute to the standardized clinical measures of Sasang typology in the near future.

Williams, M K., King, E., and Walford, Joan (1969). Brit. J. industr. Med., 26, 202-216. An investigation of lead absorption in an electric accumulator factory with the use of personal samplers. Thirty-nine lead workers and controls, in stable conditions of exposure, each wore personal lead-in-air samplers daily for two weeks. During the second week samples for blood lead, urinary lead, urinary coproporphyrin, urinary $\gamma$-aminolevulinic acid (ALA), the punctate basophil count, and haemoglobin were taken daily. Duplicate estimations were made on one day. The lead exposures of men doing almost identical jobs differed by ratios of up to four to one. This could be attributed on y to personal differences in working habits. The correlation coefficients and regression equations of the biochemical tests with lead-in-air and with each other were determined. The mean values and $95\%$ confidence limits of single determinations of some of the biochemical tests corresponding to the two commonly accepted TLVs of lead-in-air (0-20 and 0-15 mg./$m^{3}$) were calculated from the regression equations. For each biochemical test the variation due to analytical error, the variation from day to day within subjects and the residual variation about the regression on lead-in-air were calculated. Previous estimates of the latter are not known. Excessive confidence may be placed in an index of exposure due to its low coefficient of variation within subjects unless the coefficient of variation between subjects about regression is taken into account. The correction for specific gravity of estimations of lead and ALA in spot samples of urine was found to reduce slightly the residual variation between subjects about the regression on lead-in-air and to increase the correlations with lead-in-air and with the other biochemical tests, but these changes were not statistically significant. The modified method used for estimating blood lead and urinary lead is described and validated.

The pesticide is raising public interest in the world, because it causes damage to an environmental pollution and the human health remaining agricultural products and an ecosystem, in spite of the advantages. Particularly, each country restricts the residual pesticide and induces observance about the safety and usage standard so that they can control the amount of pesticide used and defend the safety of agricultural products. The habitual practice for the analysis of the residual pesticide depends on GC (gas chromatography), HPLC (high performance liquid chromatography) and GC/MS (gas chromatography/mass spectroscopy), which triturate the fixed quantity of samples, abstract and purify as a suitable organic solvent. These methods have the highly efficient in aspects of sensitivity and accuracy. On the other hand, they need the high cost, time consuming, much effort, expensive equipment and the skillful management. Carbofuran is highly toxic by inhalation and ingestion and moderately toxic by dermal absorption. As with other carbamate compounds, it is metabolized in the liver and eventually excreted in the urine. The half-life of carbofuran on crops is about 4 days when applied to roots, and longer than 4 days if applied to the leaves. This research was conducted to develop immunoassay for detecting carbofuran residue quickly on the basis of surface plasmon resonance and to evaluate the measurement sensitivity. Gold chip used was CM5 spreaded dextran on the surface. An applied antibody to Immunoassay was GST (glutathione-s-transferase). The association and the dissociation time were 176 second and 215 second between GST and carbofuran. The total analysis time using surface plasmon resonance was 13 minutes including regeneration time, on the other hand HPLC and GC/MS was 2 hours usually. The minimum detection limit of a permissible amount for carbofuran in the country is 0.1 ppm. The immunoassay method using surface plasmon resonance was 0.002 ppm.

Age-related changes in bone metabolism are well established by biochemical markers of bone matrix in serum and urine, but analysis of the residual bone matrix, which is still turning over, has not been investigated. In the present study, we measured in vivo rates of bone protein synthesis using a precursor-product method based on the exchange of ²H from ²H₂O into amino acids. Four percent ²H₂O was administered to mice in drinking water after intraperitonial (i.p) bolus injection of 99.9% ²H₂O. Mice were divided into the two groups: growing young mice were administered 4% ²H₂O for 12 weeks after an i.p bolus injection at 5 week of age, whereas weight stable adult mice started drinking 4% ²H₂O 8 weeks later than the growing group and continued 4% ²H₂O drinking for 8 weeks. Mass isotopomer abundance in alanine from bone protein was analyzed by gas chromatography/mass spectrometry. Body ²H₂O enrichments were in the range of 1.88-2.41% over the labeling period. The fractional synthesis rates (ks) of bone protein were 2.000±0.071%/d for growing mice and 0.243±0.014%/d for adult mice. These results demonstrate that the bone protein synthesis rate decreases with age and present direct evidence of age-related changes in bone protein synthesis.

저자들은 전자궁적축술과 요실금 수술후 요도폐색이 발생한 43세의 여자 환자에서 장기간의 간헐적 자가도뇨법과 약물요법으로 치료되지 않아, 외요도구 상방을 통한 요도 박리술을 시행하여 좋은 결과를 볼 수 있었다. 저자들의 견해로는 과거에 부인과 수술과 동반해서 시행하거나 혹은 복측으로 치골후방으로 접근하여 시행한 요실금수술이나 요도하부 슬링수술등의 방법으로 인해 요도 폐색이 발생시 외요도구 상방을 통한 요도박리술이 바람직할 것으로 사료된다.
