The effects of dichloromethane (CH$_2$C1$_2$), ethylacetate (EtOAc) or water ($H_2O$) fraction of Korean cabbage kimhi on accumulation of lipids in the heart, kidney and lung of rabbit fed 1% cholesterol diet for 16 weeks were studied. The amount of kimhi fraction added to the 100 g of diet was 8.3 mg of CHaC12.5.6 W of EtOAc, and 221.9 mg of $H_2O$, which are equivalent to 5% of freeze-dried kimhi added to the diet. Each group had 6 rabbits and rabbit was housed individually. Cholesterol and triglyceride concentrations of three organs were noticeably decreased due to these solvent fractions of kimhi but for phospholipid and total lipids, only CH$_2$C1$_2$ fraction group showed decreasing effects. In the heart, compared to the control, cholesterol concentrations for CE$_2$C1$_2$, EtOAc, and H2O fraction group were decreased by 42 (P<0.05),21 (P<0.05), and 8%, respectively, and triglyceride for these groups were decreased by 29 (p<0.05),4, and 11%, respectively. In kidney, cholesterol concentration for CH$_2$C1$_2$, EtOAc, and H2O fraction group were decreased by 23, 12, and 11%, respectively (p<0.05) and triglyceride concentration for CH$_2$Cl$_2$ and H2O fraction groups were significantly decreased by 51 and 21%, respectively (p<0.05). In lung, cholesterol concentrations for CItCIB, EtOAc, and H2O fraction groups were decreased by 37,20, and 22%, respectively (p<0.05) and triglyceride concentration of these groups were significantly decreased by 39, 28, and 28%, respectively (p<0.05). And phospholipid and total lipid of CH$_2$CI$_2$ fraction group were significantly decreased by 33 and 34% respectively (p<0.05). Among three organs the cholesterol content of lung was the highest followed kidney and heart. For triglyceride, heart, kidney and lung is in the order of showing the highest concentration. The phospholipid concentration was not significantly different among three organs. According to these results, we may conclude that CH$_2$C1$_2$, fraction of kimhi might have the most active component, which decreases cholesterol, triglyceride, phospholipid and total lipids concentrations in heart, kidney, and lung of rabbit fed high cholesterol diet.

The effect of water temperature (T) and body weight (W) on oxygen consumption of fasted starry flounder Platichthys stellatus was investigated in order to assess the metabolic response of this species at given conditions. The oxygen consumption rate (OCR) was measured under six different water temperatures (4, 7, 10, 13, 16 and $19^{\circ}C$) and at two different body weights (mean weight of fry group : 1.5 g; fingerling group : 37.4 g) at an interval of 5 minutes for 24 hours using a continuous flow-through respirometer. In each treatment three replicates were set up and a total 540 fish in fry groups and 90 fish in fingerling groups were used. The OCRs increased with increase of water temperature in both groups (p<0.001). Mean OCRs at 4, 7, 10, 13, 16 and $19^{\circ}C$ were 1386.0, 1601.7, 1741.0, 1799.2, 2239.1 and $2520.3mg\;O_2\;kg\;fish^{-1}\;h^{-1}$ in fry groups, and 83.8, 111.4, 126.3, 147.1, 187.7 and $221.3mg\;O_2\;kg\;fish^{-1}\;h^{-1}$ in fingerling groups, respectively. The OCRs decreased with increasing body weights at six different water temperatures (p<0.001). The relationship between water temperature and body weight is described by the following equation : OCR=1520.91+40.85T-49.22W ($r^2=0.95$, p<0.001). The energy loss by metabolic response increased with an increase in water temperature and a decrease in body weight (p<0.001). Mean energy loss rates by oxygen consumption at 4, 7, 10, 13, 16 and $19^{\circ}C$ were 907.9, 1046.5, 1141.6, 1177.0, 1467.3 and $1650.1kJ\;kg\;fish^{-1}\;d^{-1}$ in fry groups and 54.8, 73.0, 82.9, 96.2, 122.9 and $144.6kJ\;kg\;fish^{-1}\;d^{-1}$ in fingerling groups, respectively. The $Q_{10}$ values of fingerling groups were higher than those of fry groups at given temperature ranges. The $Q_{10}$ values at $4{\sim}7^{\circ}C$, $7{\sim}10^{\circ}C$, $10{\sim}13^{\circ}C$, $13{\sim}16^{\circ}C$ and $16{\sim}19^{\circ}C$ were 1.62, 1.32, 1.12, 2.07 and 1.48 in fry groups, and 2.59, 1.52, 1.67, 2.25 and 1.73 in fingerling groups, respectively.

Mean values representing the particle size distribution and some chemical properties for the cultivated soils were obtained from the analysis results of the typical profiles, which were described by the detailed soil maps throughout Korea. Analysis results of 5,215 soil samples (3,075 for paddy and 2,140 for upland) were available for the determination of mean values. The results are under. 1. Paddy topsoil contained 20.4% for clay, 5.8 for pH, 2.6% for organic matter, 10.4me/100g for exchangeable K, and 89ppm for available $P_2O_5$. Upland topsoil did 17.3% for clay, 5.5 for pH, 1.8% for organic matter, 9.lme/100g for CEC, 0.29me/100g for exchangeable K, and 103ppm for availabal $P_2O_5$. 2. Soil properies for paddy were markedly influenced by the reliefs. Topsoil contained 21.4% for clay, 6.0 for pH, 2.2% for organic matter, 10.8me/100g for CEC, 0.39me/100g for exchang-cable K and 57ppm for available $P_2O_5$ on the fluvio-marine plain, 15.3%, 5.7, 2.0%, 8.6me/100g, 0.17me/100g and 76ppm on the alluvial plain, 18.8%, 5.9, 2.7%, 10.4me/100g, 0.19me/100g and 80ppm on the valleys and fans, 25.0%, 5.7, 2.5%, 11.5me/100g, 0.26me/100g, 0.27me/100g and 141ppm on the moutain foot slopes, respectively. 3.

Intervals of one and two standard deviations about mean of an approximately normal distribution were calculated.

Phenothiazine의 직업적 노출기준(TLV-TWA)은 $5mg/m^3$으로 권고되었다. TLV-TWA의 수준은 피부자극과 변색, 각막염 그리고 태양광에 직접 노출되었을 때 나타나는 광감작반응의 가능성을 최소화하기 위해 설정되었다. 고용량의 phenothiazine을 경구 투여하면 간과 신장이 손상되며 용혈성의 빈혈이 발생한다. Phenothiazine의 피부흡수에 의한 전신 독성이 증명되어 피부흡수 "Skin" 경고주석을 권고하였다. 감작제(SEN)와 발암성 경고주석 그리고 TLV-STEL을 설정하기에는 유용한 자료가 부족하다.
