감귤류 (자몽, 레몬, 금귤, 밀감 및 오렌지)를 착즙하여 얻은 쥬스를 sep-pak C_18 cartridge를 사용하여 ascorbate 및 phenolic 획분으로 분리한 다음 pH를 달리한 in vitro 반응계에서 아질산염 소거 및 N-nitrosodimenthylamine(NDMA) 생성억제 효과를 분석하였다. 감귤류 쥬스 ascorbate 획분의 아질산염 소거능은 5ml 첨가시 pH 2.5 에서 79.9 ~ 98.6%, pH 4.2에서 48.5 ~ 86.3%였으나, pH6.0에서는 35.2% 이하였다. Phenolic 획분은 ascorbate 획분에 비해 높은 소거능을 보였으며 특히 pH6.0 에서는 ascorbate 획분에 비해 2배 이상의 높은 소거능을 나타내었다. NDMA 생성억제 효과는 phenolic 획분의 첨가시에 월등히 뛰어나 pH 2.5의 반응용액에 금귤, 밀감 및 오렌지쥬스의 phenolic 획분을 첨가했을 때 92.8% 이상이었으나, ascorbate 획분이 첨가된 경우에는 NDMA 생성 억제 효과를 거의 나타내지 못하였다. 따라서 감귤류 쥬스의 NDMA 생성억제와 관련된 주된 인자는 phenol 화합물인 것으로 사료된다. Five citrus juices were separated into a ascorbate and phenolic portion using sep-pak C_18 catridge, respectively, in order to elucidate the nitrite scavenging effect and N-nitrosodimethylamine (NDMA) formation in model system. the nitrite scavenging effect of ascorbate portion from citrus juices, in the different pH, when added with 5ml were 79.9 ~ 98.6% under the condition of pH 2.5, 48.5 ~ 86.3% at pH 4.2 and lower than 35.2% at pH 6.0. The nitrite scavenging effect was excellent phenolic portion rather than ascorbate portion. Particularly, the effect was more 2 times than ascorbate portion under the reaction condition of pH 6.0. When added the phenolic portion in the reaction mixture, NDMA formation was inhibited 92.8% or more in kum quat, mandarin orange and sweet orange juices. But the ascorbate portion was a negative response of the inhibition of NDMA formation. The inhibition on NDMA formation in citrus juice may be due to phenolic compounds were reacted.

This study was designed to observe the effects of the feeding Platycodon grandiflorum A.DC(PG) extract on the improvement of the lipids on serum in ovariectomized rats. To investigate the effects of ethanol extract, Sprague-Dawley female rats were randomly assigned to groups as follows: Sham, OVX-control and ovariectomized rats supplemented with PG at 50㎎/㎏ bw/day. Body weight gain was not significantly different in groups. The levels of total cholestcrol was higher in ovaiectornized control rats than Sham-operated rats, but supplementation of PG ethanol extracts at 50mg/kg bw/day decreased the level of cholesterol in surum. These results might be expected that ethanol extract of PG is believed to be possible protective effects for the fatty serum increasing serum lipid.

연구 배경 : 급성 신부전은 술 후 발생할 수 있는 합병증 중에서 사망률은 큰 영향을 줄 수 있으므로 이 연구를 통해 위험인자를 알아보려고 한다. 재료 및 방법 : 2004년 1월부터 2006년 12월까지 3년간 영남대학교 의과대학 부속병원에서 대장 수술을 받은 570명의 환자들을 대상으로 하였다. 환자들의 성별과 연령, 미국 마취과학회 신체등급, 동반질환, 수술의 종류, 응급수술의 여부, 수술 시간, 재수술의 여부, 술 중의 투약 상황, 술 후에 자가 통증 조절기에 사용한 약제, 술 중에 저혈압의 유무, 수혈 여부, 술 후 기계적 환기를 시행한 경우를 비교하였다. 결과 : 비교 결과에서 성별과 수술의 종류, 응급 수술의 여부, 개복여부 등에는 유의한 차이를 보이지 않았다. 반면 환자의 나이와 수술 시간, 재수술의 여부, 술중에 이뇨제 등을 사용한 경우, 술 중에 저혈압의 유무, 술 후에 기계적 환기를 시행한 경우 등에는 유의한 차이를 보였다. 결론 : 이상의 결과로 급성신부전의 원인은 어느 한 가지라고 하기 보다는 위험인자에 얼마나 노출되어 있는가가 결정하는 것 같고, 그 원인들이 모여서 상승효과를 내는 것 같다. 그러므로 수술 전부터 많은 위험에 노출된 환자는 술 중 더 적극적인 감시를 시행하여 수술 후의 합병증 발생을 줄이는 노력을 기울여야 하겠다. Background : Acute renal failure is one of the leading causes of postoperative morbidity and mortality. The purpose of this study was to determine the risk factors that are associated with acute renal failure after colorectal surgery. Materials and Methods : Five hundred seventy patients who operated colorectal surgery at the Yeungnam University Medical Center over three years from 2004 to 2006 were enrolled in this study. The effects of gender, age, ASA classification, concomitant disease, surgery type and duration, reoperation, urogenital manipulation, medication, hypotension, hypovolemia, transfusion, and postoperative ventilatory care on the occurrence of acute renal failure after colorectal surgery were studied. Results : The major risk factors of acute renal failure after colorectal surgery were age of patients (P=0.003), ASA classification (P<0.001), concomitant disease (P<0.001), duration of the time surgery (P=0.034), reoperation (P=0.001), use of intraoperative diuretics (P=0.005), use of postoperative diuretics (P<0.001), intraoperative hypotension (P=0.018), intraoperative transfusion (P<0.001), postoperative transfusion (P<0.001), and postoperative ventilatory care (P=0.001). Conclusion : Multiple factors cause synergistic effects on the development of acute renal failure after colorectal surgery. Therefore, efforts to reduce the risk factors associated with acute renal failure are needed. In addition, intensive postoperative care should be provided to all patients.

To elucidate the mechanism of cytotoxicity on chromium in cultured human skin melanoma cells (SK-MEL-3), XTT assay was performed for the measurement of cytotoxicity induced by chromium after human skin melanoma cells were cultured for 48 hours in the medium containing various concentrations of chromium trioxide (CrO₃). In this study, chromium trioxide decreased cell viability dose-dependent manner after human skin melanoma cells were cultured in various chromium trioxide concentration of for 48 hours. In cell viability, XTT_(90) and XTT_(50) was determined at 3uM and 30uM chromium trioxide, respectively, so chromium trioxide was highly toxic by toxic criteria of Brenfreund et al. From above the results, it is suggested that chromium trioxide showed cytotoxicity by the decrease of cell viability in cultured human skin melanoma cells.
