매운맛 성분(capsaicin, CAP)이 암발생에 미치는 영향에 대한 분자적인 수준에서의 기초 정보를 확보하기 위해, 식이 CAP의 투여가 동물 조직 중 proto-oncogene 의 발현에 미치는 영향을 조사하였다. ICR mouse를 4 group으로 분류하여 각각 식이CAP 농도가 0, 5, 20, 100ppm이 되도록 조제한 먹이로 4주 동안 사육하였다. 사육기간 종료 후 동물들의 중요장기를 적출하여 total RNA를 분리하고, proto-oncogene(c-jun, c-myc, H-ras, erbB, p53)의 발현 수준을 slot blot hybridization assay를 통해 살펴 보았다. 이때, control probe로는 18SrRNA를 사용하였다. 그 결과, c-jun proto-oncogene의 발현은 각 주요 장기조직에 따라 다른 양상을 나타내었는데, 식이CAP 투여량이 증가함에 따라 간과 신장에서 그 발현이 증가하며, 위에서는 CAP 20ppm까지는 c-jun의 발현이 증가하다. 100ppm 투여시에는 감소하는 것으로 나타났으며, 비장에서는 식이CAP 투여량이 증가함에 따라 감소하는 경향을 보였다. 한편, tumor suppressor gene인 p53의 경우, 간에서만 CAP 20, 100ppm 처리시 약하게 발현되었다. 이들 결과로 보아, 식이 CAP에 의한 proto-oncogene의 발현은 CAP 투여량에 따라 그 정도를 달리하며, 그 발현 정도는 조직 특이성을 나타내는 것으로 평가된다.

This study examined the physiological and psychological effects of wearing a winter cap at rest in a cold environment. Seven older males participated in two separate trials: wearing a winter cap (CAP) and non-wearing a winter cap (CON). The experiment was conducted for 60 min in a climatic chamber (air temperature $7.8{\pm}0.3^{\circ}C$ with $43{\pm}2%RH$) with sedentary posture. Microclimate temperature at the vertex of the head was $6.88^{\circ}C$ higher in CAP compared to CON (p<.01). Microclimate humidity at the vertex was lower in CAP than in CON only during the last 5 min (p<.01). Skin temperature at the forehead in CAP was higher than in CON (p<.01). During the last 5 min, rectal temperature was higher in CAP than that in CON (p<.05). Unlike CAP, the heart rate in CON during the last 5 min decreased significantly compared to the initial 5 min (p<.05). Subjects also felt less cold on the head/face in CAP than that in CON (p<.01). The results indicate that wearing a cap for elderly males positively affected body temperature regulation and cardiovascular response in cold environments. The importance of wearing warm hats for elderly males in winter should be emphasized.

Objective: To assess the potency of calcium propionate (CAP) used as silage additive, an experiment was carried out to evaluate the effect of CAP on the nitrogen transformation, fermentation quality and aerobic stability of alfalfa silages. Methods: Alfalfa was ensiled with four levels of CAP (5, 10, 15, and 20 g/kg of fresh weight [FW]) in laboratory silos for 30 days. After opening, the silages were analyzed for the chemical and microbiological characteristics, and subjected to an aerobic stability test. Results: The increasing proportion of CAP did not affect pH, lactic acid (LA) concentrations and yeast counts, while linearly decreased counts of enterobacteria (p = 0.029), molds (p<0.001) and clostridia (p<0.001), and concentrations of acetic acid (p<0.001), propionic acid (p<0.001), butyric acid (p<0.001), and ethanol (p = 0.007), and quadratically (p = 0.001) increased lactic acid bacteria counts. With increasing the proportion of CAP, the dry matter (DM) loss (p<0.001), free amino acid N (p<0.001), ammonia N (p = 0.004), and non-protein N (p<0.001) contents were linearly reduced, whereas DM (p = 0.048), water soluble carbohydrate (p<0.001) and peptide N (p<0.001) contents were linearly increased. The highest Flieg's point was found in CAP10 (75.9), represented the best fermentation quality. All silages treated with CAP improved aerobic stability as indicated by increased stable hours compared with control. Conclusion: The addition of CAP can suppress the undesirable microorganisms during ensiling and exposure to air, thereby improving the fermentation quality and aerobic stability as well as retarding the proteolysis of alfalfa silage. It is suggested that CAP used as an additive is recommended at a level of 10 g/kg FW.

The monoclonal antibody to chloramphenicol(CAP) was produced to develop an enzyme-linked immunosorbent assay(ELISA) for residual CAP. An immunogen(CAP-BSA) was prepared by immunogen, antibody titer was measured by indirect ELISA. Spleen cells form the immunized mouse were fused with SP2/OAg14 myeloma cells. Among hybridomas selected in HAT media, 6 clones shown high antibody titer to CAP were subjected to cloning by limit dilution, and all of the monoclonal antibodies(MCA1, 2, 3, 4, 5, 7 and 9) produced by each clone were identified as IgG1 by ELISA isotyping analysis. Competitive ELISA condition was established by using the purified monoclonal antibody MCA1 as primary antibody and CAP-HSA conjugate as coating antigen. Standard curve of CAP(n=28) showed that the lowest detection limit of CAP is 20ng/ml level. The cross-reactivities of the 6 monoclonal antibodies showed that CAP sodium succinate. CAP base, P-nitrophenol, and p-nitrobenzyl alcohol were 89∼178, 0.050∼2.237, 0.056∼0.794 and 0.013∼7.939%, respectively. No cross-reactivities were observed with phenylalanine, tyrosine, glutamine, thiamphenicol, neomycin, streptomycin, gentamicin, sulfamethazine, sulfathiazole, chlortetracycline and p-aminobenzoic acid.

New Si pin photodiodes with $p^+-cap$ region have been designed and fabricated for the application in a PDIC of the optical pick-up system. The fabricated devices were designed with the incident optical window of $120\mu\textrm{m}$ and were classified into three structures according to <$p^+-cap$ dimensions. As the result of experiments, the devices with the $p^+$-cap dimension of $0\mu\textrm{m}$(no cap), $65\mu\textrm{m}$, and $120\mu\textrm{m}$ showed the sensitivity of 1.0 A/W, 0.86 A/W, and 0.6 A/W, respectively.

The factors to influence the travelling distance of sprayed particles for the medium range nozzle may by the groove depth of swirl plate, the cap slope, the diameter of cap hole, and pressure. 1. This study was conducted to examine Interaction effects among four factors to the travelling distance. The results of this study are summarized as followa; a) Interaction effects among four factors the groove depth(G), cap slope(C), diameter of cap hole(D), and pressure (P), were significant to influence the travelling distance except for $G{\times}P,\;C{\times}D{\times}P\;and\;G{\times}C{\times}D{\times}P$. b) Interaction effects with the pressure were very smaller than interaction effects among the other factors. c) Effect of change of the groove depth of swirl plate on the travelling distance of sprayed particles was generally a linear, the increasing rate of the change was about 0.345, which was very significant. d) Effect of change of cap slope on the travelling distance was generally a linear or a dull quadratic, the increasing rate was very small. e) Main effect of change of cap slope in the medium range nozzle was very smaller than that of the close range nozzle on the travelling distance, which was estimated by the changing of turning radius of flowing course in nozzle. f) Interaction effect between two factors in the medium range nozzle was more significant than that of the close range nozzle on the travelling distance.

본보는 분뇨처리장에서 잉여 슬러지로 발생하는 유기성 슬러지를 지렁이 먹이로 활용하여 처리하는 폐기물 자원화 기술의 하나인 Vermicomposting 방법을 효율적으로 운영관리하기 위한 온도, pH, 사육밀도의 적정사육조건과 Vermicomposting 의 부산물인 분변토의 비료성분과 안전성을 조사하였는데 지렁이 생존율은 온도 $10-15^{\circ}C$ 에서 98.3%, pH 5.8-7.5에서 75% 및 밀도 $1/79.8cm^3$에서 100%였다. 지렁이 생체량 변화는 온도 $10-15^{\circ}C$에서 266%, pH 5.8-7.5에서 227% 및 밀도 $1/79.8cm^3$에서 325% 로 많이 증가하였으며, 지렁이 분변토 발생량은 온도 $20-25^{\circ}C$에서 0.06 g/cap./day, pH 5.8-7.5에서 0.065 g/cap./day 및 밀도 $1/79.8cm^3$에서 0.1 g/cap./day로 많이 발생하는 것으로 나타났다. 또한, 지렁이 난포 생산은 온도 $10-15^{\circ}C$에서 3.8 ea./cap./6weeks, pH 5.8-7.5에서 2.95 ea./cap./6weeks 및 밀도 $1/79.8cm^3$에서 3.16 ea./cap./6weeks로 많이 생산되었으며, 지렁이의 먹이로 공급된 슬러지와 먹고 배설한 분변토의 pH는 6.2에서 5.7로 낮아지며 휘발성 고형물질은 2.9% 감소되는 것으로 나타났다. 또한 $NH_3-N$는 $6.984{\mu}g/g$에서 $0.991{\mu}g/g$으로 감소한 반면, $NO_3-N$는 $3.213{\mu}g/g$에서 $7.706{\mu}g/g$으로 증가되는 것으로 나타났다. 그리고 지렁이 분변토 중의 분원성 대장균은 슬러지에서 보다 88.6-99.1% (평균 95.7%) 정도 감소되는 것으로 조사되었으며 병원성 장내세균인 Salmonella, Shigella, Vibrio 등은 검출되지 않았다. 이와 같은 결과로 미루어 볼 때 Vermicomposting 기술은 유기성 슬러지를 재이용함과 동시에 폐기물을 처리하는 효과가 있으며 앞으로 이를 보급함으로써 폐기물 처리에 중요 분야가 될 수 있을 것으로 판단되었다.

The effect of dietary capsaicin (8-methyl-N-vanillyl-6-nonenamide, CAP) on drug-metabolizing enzyme activities was investigated in mice. Male ICR mice were divided into 4 groups and fed diets containing 0, 5, 20, 100 ppm CAP for 4 seeks. Hepatic drug-metabolizing enzyme activities and serum alanine aminotransferase and aspartate transaminease activities were measured. There was no difference in hepatic alanine aminotransferse and aspartate transaminase activities among the groups. Hepatic microsomal cytochrome P450 in CAP fed groups, but p-nitrophenol hydroxylase and the cytosolic acitivity of glutathione S-transferase activities were decreased in the dietary CAP supplemetned groups compared to the control. These results suggest that the dietary CAP at a low dose differentially modulates drug-metabolizing enzyme acitvities without causing hepatic toxicity.
