  • 인체에 투여된 약물의 반응은 개체간에 현저한 차이가 있으며 특히 환자에게 투여된 약물의 효과가 상이하게 나타남으로써 치료의 실패나 흑은 약물의 유해작용으로 나타나기도 한다. 이러한 개체 상호간의 약물반응의 차이는 환경적인 요소, 영양학적인 요소, 연령, 병용한 다른 약물 및 이미 앓고 있는 질병 등에 의해서도 영향을 받으나 특히 유전적으로 결정된 약물대사 능력의 차이에 의해서도 기인된다. 이러한 측면에서 약물 대사의 유전적인 다양성과 비정상적인 반응을 다루는 약물유전학의 중요성은 최근 두드러지게 대두되고 있다. 특히 유전적인 요인으로 개체간의 차이는 효소의 유전적인 결핍과 관련이 있으며 이 결핍은 생체이물질에 대한 반응의 다양성을 설명할 수 있는 약물대사 능력의 다형성에 기인한다. 또한 약물반응의 다양성은 인종간, 특히 동양인과 서양인에서의 약물반응에서도 차이가 있어 각 인종간의 약물반응의 차이에 대한 연구와 이의 원인규명에 대하여 많은 관심이 집중되고 있다. 이와 같은 견지에서 약물용량과 약물반응, 특히 약동학적 변화의 인종간의 차이와 각 개인의 차이 및 이의 원인에 대하여 살펴보고자 한다.

  • Soybean plants inoculated Bradrhizobium japonicum MN 110 were grown in outdoor perlite pots with nitrogen free nutrient solution containing 1.0 mM-P(control) and 0.05 mM-P(stress) and harvested at 28, 35, 42 and 49 days after transplanting (DAT) to examine the effect of phosphorus deficiency on ureide concentration of and distribution to diffrent plant organ in nitrogen fixing soybean plant during the vegetative growth. Total dry mass of control plants increased 8.9 fold and that of phosphorus deficient plant increased 2.7 fold during the experimental period. Phosphorus deficiency reduced total phosphorus and nitrogen accumulation by 80%,40% respectively, at 28 DAT and 93%, 84%, respectively, at 49 DAT. Nitrogen concentration was reduced by phosphorus deficiency in all tissues with leaf and stem tissues affected to a greater degree than nodule and root tissues at every sampling date. Phosphorus deficiency significantly reduced soluble reduced-N and ureide-N concentration in leaf and stem but did not affect those in root. The proportion of soluble reduced-N in leaf was reduced from 60% to 50% but increased from 10% to 20% in the roots. The proportion of ureide-N in leaf of control plants was higher than that in phosphorus deficient plants, whereas, roots of phosphorus deficient plants contained a higher propotion of ureide-N than those of control plants. These indicated that phosphorus deficiency not only inhibit nitrogen fixation of nodules but also restrict the translocation of fixed nitrogen out of the root system into the xylem.(Received April 4, 1997; accepted May 2, 1997)

  • This study examines the effects of choline deficiency and 2-acetylaminofluorene(2-AAF) on the lipid peroxide values, glucose 6-phosphatase(G6Pase) and glutathione S-transferase (GST) activities in rats fed different dietary fats. Weanling Sprague Dawley male rats fed the diets containing 15% beef tallow or 15% corn oil with vitamin fortification mixture or choline free vitamin mixture for 10 weeks. At 3th and 5th week, 2-AAF was injected twice each week intraperitoneally. Total 2-AAF injection was four times. 2-AAF and choline deficiency increased lipid peroxidation in corn oil groups, so the role of 2-AAF and choline deficiency in lipid peroxidation was more important in corn oil groups than beef tallow groups. G6Pase activities tended to be decreased by 2-AAF in choline deficient groups, and in corn oil groups, the enzyme activities were decreased significantly in all subgroups compaired to beef tallow groups. GST activities were increased by 2-AAF in beef tallow groups and choline deficiency in corn oil groups, and might defence against carcinogen metabolism and lipid peroxidation.

  • To evaluate processing suitability of lipoxygenase (LOX)-free genotype soybeans (Jinyang, 05C4 and LS), quality characteristics and antioxidant activities of their Doenjang products were compared to those of Doenjang made from Taekwang soybean (LOX-present) as the control. Moisture and crude protein contents of Doenjang were significantly higher in LS than the control. Crude lipid content was not significantly different and was in the range of 7.92~8.22% in all samples. Carbohydrate content was significantly lower in LS than Taekwang. Content of reducing sugar in Doenjang was significantly higher in Jinyang than Taekwang. Contents of amino-type nitrogen were significantly higher in LOX-free cultivars than Taekwang. Colors of 05C4 and LS Doenjang were not different compared to that of Taekwang, whereas Jinyang Doenjang showed a noticeable color difference. Taekwang Doenjang had a slightly stronger savory taste than another sample. LOX-free cultivars had a strong salty taste. Flavor was the strongest in LS, whereas overall acceptability showed little difference among all samples. The total amino acid content was slightly higher in Jinyang and 05C4 than Taekwang, and content of essential amino acids was higher in Doenjang from LOX-free cultivars than Taekwang. Isoflavon content was significantly higher in Doenjang ($522.16{\sim}684.46{\mu}g/g$) made from LOX-free cultivars than in Taekwang ($374.79{\mu}g/g$). Total phenol content was significantly higher in 05C4 and LS, and flavonoid content was significantly higher in LS than Taekwang. Antioxidant activities were highest in Jinyang based on DPPH radical scavenging and reducing power. ABTS radical scavenging activity was significantly higher in Doenjang made from LOX-free cultivars than Taekwang. These results suggest that Doenjang from LOX-free cultivars could have a suitable genotype for Doenjang processing since it is more effective in terms of amino acids, isoflavone contents, and antioxidant activity.

  • The purposes of this study were to investigate the effect of seleniumc (Se) and vitamin E on activity of enzyme relevant to lipid peroxidation in alcohol administrated rats. Seventy two male rats of Sprague-Dawley strain weighing about 58~62g were divided into 12groups. The dietary Se levels were 0, 0.4 and 10mg and the dietary vitamin E levels were 0 and 150mg per kg diet, respectively. Alcohol-administrated groups received drinking water solution containing 10% of ethanol from the 3-weeks of experimental periods. The obtained experimental results are summarized as follow: The ${\gamma}$-GTP activity in plasma was higher in alcohol administrated groups and high selenium group (HSe) and low selenium group (LSe) than in control groups (CSe). The ${\gamma}$-GOT and GPT activities were higher in alcohol groups. The ${\gamma}$-GTP activity was significantly influenced by alcohol in LSe groups than in other groups. The glutathione peroxidase (GSH-Px) activity of plasma was significantly lower in LSe groups than HSe and CSe groups. The GSH-Px activity of microsomal and cytosolic fraction was slightly lower in alcohol groups and was about a half value lower in HSe and LSe groups than CSe groups. There was negative correlation between plasma Se level and GSH-Px activity of cytosolic fraction in HSe groups (r=- 0.662, p<0.001) and positive correlation in LSe groups (r=0.640, p<0.001). The GSH S-transferase activity in microsomal and cytosolic fraction was slightly higher in alcohol administrated but vitamin E nonadministrated groups, and significantly higher in LSe groups than in other groups. The catalase activity in mitochondria was lower in HSe than CSe groups, but rather higher in LSe groups. The superoxide dismutase (SOD) activity in cytosolic fraction of liver was not found any effect in all groups. The cytochrome P-450 was higher in alcohol groups, but significantly lower in HSe groups. In conclusion, the deficiency of Se and vitamin E develops the hyperoxidation of liver lipid through the increase of activity of enzyme related to the lipid peroxidation and alcohol administration appears to further increase of hyperoxidation of liver lipid.
