Effects of Acanthopanax senticosus extract (AS) on blood sugar content and serum lipid profiles of streptozotocin-induced diabetic rats were investigated. Experimental groups were classified into four groups, that is, normal control (NC) group, diabetic mellitus (DM) group, AS-fed group and DMAS-fed group. The AS group showed lower feed efficiency than the NC group, but the efficiency of DMAS group was higher than DM group. DMAS group showed the decreased water intake and urine by $45.5\%$ and $23.7\%$ respectively, compared with DM group. Compared with DM group, DMAS group decreased blood sugar by $46.9\%$ and triglyceride by $17.8\%$, total cholesterol by $10.0\%$ and LDL cholesterol by $22.0\%$ in serum, but increased serum HDL cholesterol by $14.4\%$ The relative percentage of liver or kidney per body weight, and the serum ALT activity in DMAS group were lower than those of DM group. There were no significant differences in hepatic glutathione(GSH) contents and total xanthine oxidase(XOD) activities among experimental groups. The hepatic lipid peroxide(LPO) content in DMAS group decreased by $54.6\%$ compared with that in DM group. The XOD (O type) and the ratio of O type to total type of both STZ-treated groups (DM and DMAS) were higher than those of NC group, but less conversion of D to O type was observed in DMAS group than in DM group. There was no significant difference in GST activity between NC and AS, but STZ-treated groups showed lower glutathione S-transferase(GST) activity than NC. In conclusion, it seems that AS reduces blood sugar by inhibiting the activity of xanthine oxidase type O as an oxygen-free radical generating system which induces the tissue damage. Antidiabetic effect of AS may regulate diabetes-induced high lipid profiles in blood.

Objectives: The effects of peroxisome proliferator-activated receptor ${\gamma}2\;(PPAR{\gamma}2)$ Pro12Ala (P12A) polymorphism on body mass index (BMI) and type 2 diabetes are well documented; however, until now, only a few studies have evaluated the effects of this polymorphism on body fat distribution. This study was conducted to elucidate the effects of this polymorphism on computed tomography (CT)-measured body fat distribution and other obesity-related parameters in Korean female subjects. Methods & Results: The frequencies of $PPAR{\gamma}2$ genotypes were: PP type, 93.0%; PA type, 6.8%; and AA type, 0.2%. The frequency of the A allele was 0.035. Body weight (P .012), BMI (P .012), and waist-to-hip ratio (WHR) (P .001) were significantly higher in subjects with PA/AA compared with subjects with PP. When body composition was analyzed by bioimpedance analysis, lean body mass and body water content were similar between the 2 groups. However, body fat mass (P .003) and body fat percent (P .025) were significantly higher in subjects with PA/AA compared with subjects with PP. Among overweight subjects with BMI of greater than 25, PA/AA was associated with significantly higher abdominal subcutaneous fat (P .000), abdominal visceral fat (P .031), and subcutaneous upper and lower thigh adipose tissue (P .010 and .013). However, among lean subjects with BMI of less than 25, no significant differences associated with $PPAR{\gamma}2$ genotype were found, suggesting that the fat-accumulating effects of the PA/AA genotype were evident only among overweight subjects, but not among lean subjects. When serum lipid profiles, glucose, and liver function indicators were compared among overweight subjects, no significant difference associated with $PPAR{\gamma}2$ genotype was found. Changes in body weight, BMI, WHR, and body fat mass were measured among overweight subjects who finished a 1-month weight lose program of a hypocaloric diet and exercise; no significant differences associated with $PPAR{\gamma}2$ genotype were found. Conclusions: The results of this study suggest that the $PPAR{\gamma}2$ PA/AA genotype is associated with increased subcutaneous and visceral fat areas in overweight Korean female subjects, but does not significantly affect serum biochemical parameters and outcomes of weight loss programs.

본 연구는 미나리(Oenanthe javanica, MNR), 율무(Coicis lachryma-jobi L. var., YM) 및 차전자(Plantaginis asiatica L, CJJ) 물 추출물이 지질 대사 관련 효소들인 lipoprotein lipase(LPL), acyl-CoA synthetase(ACS) 그리고 carnitine acetyltransferase(CAT) 활성에 유익한 영향력을 미치는지 알아보았다. LPL와 ACS는 비만 모델군 Zucker fatty 흰쥐(fa/fa)와 대조군인 Zucker lean 흰쥐(lean)의 부고환 지질과 간에서 각각 분리하였다. MNR이나 YM 물 추출물 처리는 일반(lean) 및 비만(fa/fa) 흰쥐로부터 분리한 LPL 활성을 현저하게 감소시켰다. MNR, YM 그리고 CJJ 물 추출물 10000 ppm을 처리했을 때 fa/fa LPL 활성이 각각 32.5%, 30.1% 그리고 22.8% 증가하였다. Lean ACS 활성이 대조군과 비교하여 YM 물 추출물에서 현저히 증가하였고 MNR 물 추출물 처리는 대조군과 비교하여 fa/fa ACS 활성을 현저하게 증가시켰다(p<0.05). 10000 ppm MNR 물 추출물은 대조군과 비교하여 fa/fa ACS 활성을 12배까지 증가시켰다. CAT 활성이 대조군보다 10000 ppm과 2000 ppm CJJ 물 추출물 군에서 현저히 높았다. 따라서 MNR, YM 그리고 CJJ 물 추출물은 비만한 사람에게 지질 대사와 관련된 효소 활성에 기인하여 유익한 효과가 있을 것으로 추정된다.

암은 한국인의 사망원인 중 1위이며, 간암은 위암, 폐암과 함께 한국인의 3대 암의 하나로 발생 빈도가 높은 암이나, 대부분의 환자가 자각증상이 없어 수술이 가능한 시기를 지난 후에 진단되어 다양한 치료에도 불구하고 생존율이 낮다. 간암은 진단 시 종양의 크기가 비교적 크며, 주위 정상 간 조직의 견딤선량이 낮아 통상적인 방사선치료로는 간암세포의 치사량을 조사할 수 없어 표적장기에는 다량의 방사선을 조사하면서 주위정상조직에는 조사량을 최소로 할 수 있는 세기조절 방사선치료의 필요성은 매우 크다. 그러나 간암이나 폐암에서는 호흡이나 심박동, 장의 연동운동 등으로 상, 하, 좌, 우, 전, 후 방향으로 종양이 움직임으로 계획된 치료선량이 정확한 부위에 전달되는지에 대한 QA 기법이 개발되어 있지 않아 세기조절 방사선치료의 이론적인 많은 이점에도 불구하고 실제 임상에서의 치료는 활발하지 못하다. 본 연구에서는 35예의 간암환자를 대상으로 하여 복잡한 술기가 필요하지 않아 환자가 불편하지 않고 환자의 치료시간도 지연시키지 않으면서, 임상적용이 용이한 QA 방법을 고안하여 간암환자의 임상적용가능성을 입증하고자 하였다. 모든 환자에서 호흡으로 인한 종양의 이동폭이 가장 크다고 보고되고 있는 상하의 margin은 횡격막의 상하 이동을 5회 측정하여 평균값으로 정하고, 이 평균값만큼 상하 자동으로 반복 이동하도록 특수 제작한 장치 위에 팬텀을 고정하여 환자에서와 같은 조건으로 방사선을 조사한 후 방사선조사 선량을 TLD와 전리함으로 측정하고 컴퓨터 계산치와도 비교하여 3% 이내의 오차를 확인하였다. 환자의 첫 번째 치료에서 만든 확인 필름과 인체모형 팬텀에서 같은 방법으로 방사선을 조사하여 만든 확인 필름을 필름 스캐너로 선량을 측정한 후 90% 등선량 곡선을 비교하여도 큰 차이를 발견할 수 없어 임상에서 적용 가능한 QA 기법으로 제안하고자 한다.

Distribution of rhEGF in the skin, plasma and several organ tissues following topical application of $^{125}I-rhEGF$ (0.4${\mu}$Ci) solution in 25% Pluronic F-127 on 154$mm^2$ normal and damaged (burned and stripped) skins of hairless mice was examined. The radioactivity in the stripped skin tissues increased as a function of time, and was 10-20 times higher than that in the normal and burned skins. The fractions of intact drug in the skin tissues were 40-60% for the normal and burned skins, and 60-80% for the stripped skin. It indicates that the stratum corneum layer behaves as a barrier for the dermal penetration of the drug. The radioactivity in the plasma was much higher for the stripped skin than for the normal and burned skins. However, the concentration of intact drug in the stripped skin was comparable to those in the normal and burned skins indicating most severe degradation (or metabolism) of the drug in the stripped skin. As a result, the fraction of intact drug in the plasma was lowest for the stripped skin (<10%). Body organ distribution of the drug was much higher for the stripped skin. The concentration in the stomach. Both in total radioactivity and intact drug, showed more than 10-times higher value than in the other organs (liver, kidney and spleen). The fraction of intact drug in each organ tissue was below 10-20%. And generally lowest for the stripped skin. The lowest fraction of the drug for the stripped skin could not be explained by the activity of the aminopeptidases in the skin since it was lower for the stripped skin than for the normal skin. Thereover, the fraction of intact drug appears to be determined by the balance between dermal uptake and systemic elimination of the drug, for example. The mechanism of dermal uptake of rhEGF was examined by topical applying 200${\mu}$l of 25% Pluronic F-127 solution containing 0.4 ${\mu}$Ci of $^{125}I-rhEGF$ and 0.14${\mu}$Ci of $^{14}C$-inulin (a marker of passive diffusion). The radioactivity of $^{125}I-rhEGF$ at each sampling time point (0.5, 1, 2, 4 and 8hr) was correlated (p<0.05) with the corresponding radioactivity of $^{14}C$-inulin. It appears to indicate the rhEGF may be uptaken into the skins mainly by the passive diffusion. This hypothesis was supported by the constant specific binding of EGF to the skin homogenates regardless of the skin models. Receptor mediated endocytosis (RME) appears to contribute negligibly, if any, to the overall uptake process.

The distribution, metabolism and excretion of CKD-602{20(S)-7-[2-(N-Isopropylamino)ethyl]camptothecin HCI), a new camptothecin derivative, were investigated in rats after a sing le administration of CKD-602. 1. The tissue levels of CKD-602 given to mice by the intravenous route at a dose of 20mg/kg were the highest in intestine, followed in descending order by kidney, liver, stomach,lung, heart, spleen and plasma. The concentrations of CKD-602 after 24hrs decreased to less than 2% of the peak level in most tissues except the skin. The urinary and fecal excretion of CKD-602 were 47.6% and 44.4% of the administered dose, respectively, with 0.7% remaining in the rinse. 2. After administration of CKD-602 at 10mg/kg in rats, metabolism of this compound was examined in plasma, urine, and feces. The plasma samples were collected for 24hr, urinary and fecal samples for 72hr. While any peak of CKD-602 in HPLC chromatograms was not detected from plasma and urine it was detected in feces (peaks, 9.8 min). However, additional peak area was about 0.5% of the peak area of parent CKD-602. Therefore, CKD-602 may be eliminated with the parent form and rarely metabolized in the body. 4. After I.v. administration of CKD-602 at 10mg/kg in rats, urinary and fecal excretions were examined for 72hrs post dose period. 87% of total urinary excretion of CKD-602 was excreted within 8hr after administration, 53%, and 32% of total fecal excreted amounts were determined in 0-24 hr and 24-48hr periods, respectively. The total excretion amounts of CKD-602 into urine and feces were 94% of the administered dose.
