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.

Metallothioneins (MT) are a group of low-molecular weight, cysteine-rich, intracellular proteins that are encoded by a family of genes containing at least 10 functional isoforms in human. The expression and induction of these proteins is associated with protection against DNA damage, oxidative stress, and apoptosis. Many studies have shown increased expression of MT in various human tumors, whereas MT is down-regulated in certain tumors such as hepatocellular carcinoma and liver adenocarcinoma. Hence, the expression of MT is not universal to all human tumors but may depend on the differentiation status and proliferative index of tumors, along with other tissue factors and gene mutations. Using Northern blot analysis, we found that laminin induced expression of MT-1 in HSG and PC12 cells, which can be differentiated by laminin, but had no effect on MB-231, MDA-435, and PC-3 cells, which cannot be differentiated by laminin. In addition, we analyzed the expression level of the MT-1 gene in five prostate cancer cell lines possessing different metastatic potential. The expression of MT-1 in normal and less malignant cells (RWPE-1 and WPE1-NA22) was high and up-regulated by laminin, whereas the expression of MT-1 in WPE1-NB14, WPE1-NB11, and WPE1-NB26 cells (malignant) was extremely low and not elevated by laminin. These results suggest that the MT-1 gene is involved in laminin-mediated differentiation and affects the metastatic potential of tumor cells.

This study was performed to investigate the effects of dietary protein levels(5% and 15% PEP), caffeine or green tea powder on body fat deposition in rats. Male weanling Wistar rats weighting the average of 90g were allotted into 6 experimental groups, each of which was fed two different levels of dietary protein with or without caffeine or green tea powder(5p+0.15% caffeine ; 5p+6.1% green tea powder ; 15p+0.15% caffeine ; 15p+6.1% green tea powder) during 8 weeks of the experimental period. Caffeine and green tea powder were supplemented at the levels of 0.15% and 6.1% of experimental diets. The rats fed 5% PEP diet which had received caffeine or green tea powder showed significantly(p<0.01) reduced gain in body weight. The food efficiency of which rats fed both 5% and 15% PEP diet supplemented with 6.1% green tea powder was significantly low(p<0.05, respectively) compared with the control group. Rats fed diets containing 0.15% caffeine and 6.1% green tea powder showed the significant reduction(p<0.01) of hite adipose tissue weight, triglycerides levels of liver and plasma. The addition of 0.15% caffeine or 6.1% green tea powder to 5% PEP diet resulted in significantly(p<0.01) higher levels of plasma total cholesterol, free cholesterol, cholesterol ester, but HDL-cholesterol levels were significantly(p<0.01, in 5% PEP group) high. The atherogenic index(Tchol-HDLchol/HDLchol) in rats fed 6.1% green tea powder diets decreased especially compared with the control group.

Objectives This study was intended to clarify the anti-inflammation and anti-oxidation effects of gamikyejakjimo-tang herbal acupuncture (GKHA) for osteoarthritis. Methods Osteoarthritis was induced by injection of MIA into right knee joint cavities of rats. Rats were divided into a total of 4 groups (n=8). The 4 groups were normal group, control group, positive comparison group and expeimental group. Indomethacin and GKHA were medicated for a total of 4 weeks. After that, functions of liver and kidney by AST, ALT, creatinine, BUN, DPPH and ABTS free radical scavenging activity, ROS (reactive oxygen species) production, NO (Total Nitric oxide), IL-$1{\beta}$, IL-6, TNF-${\alpha}$ production, weight changes in the hind legs of MIA-induced osteoarthritis rat, serum PGE2, TIMP-1, MMP-2, MMP-9, LTB4, hs-CRP, and white blood cells, neutrophils, lymphocytes, monocytes were measured. The volume of cartilage was observed by micro CT arthrography. H&E and Safranin-O staining were used to examine the injury of synovial tissue. Results 1. In the hind leg weight bearing measurement, level of weight was increased. 2. AST, ALT, BUN, creatinine were decreased. 3. The production of total white blood cell was decreased, and the production of neutrophils, lymphocytes, monocytes were significantly decreased. 4. The production of NO, PGE2, TIMP-1, MMP-2, MMP-9, LTB4 were significantly decreased, and the production of hs-CRP was also decreased but with no significance. 5. The cartilage volume was significantly increased. 6. In H&E staining and Safranin-O staning, the cartilage cell appeared to be proliferated, and proteoglycans appeared to be increased.

This study was carried out to estimate beneficial effects of medicinal plant [Oenanthe javanica (MNR), Coicis lachryma-jobi L. var. (YM), Plantaginis asiatica L. (CJJ)] water extracts on activities of key enzymes such as lipoprotein lipase (LPL), acyl-CoA synthetase (ACS) and carnitine acetyltransferase (CAT) on lipid metabolism. LPL and ACS were extracted from the epididymal adipose tissue and liver of Zucker lean rats (lean) and Zucker fatty rats (fa/fa). MNR or YM water extract treatment significantly reduced the activity of lean and fa/fa LPL. When 10000 ppm of MNR, YM, and CJJ water extracts were tested, they decreased fa/fa LPL activity by 32.5%, 30.1% and 22.8%, respectively. The lean ACS activity was significantly higher in YM water extract treatment compared to the control and the MNR water extract treatment significantly increased the activity of fa/fa ACS, compared to the activity in the control (p<0.05). MNR water extract activated fa/fa ACS activity by 12-fold compared with control at 10000 ppm concentration. CAT activity was significantly higher in 10000 ppm and 20000 ppm CJJ water extract treatment than in the control. Thus, the MNR, YM and CJJ water extracts may have beneficial effects due to activities of enzymes related with fat metabolism in obese humans.

Hepatoma is one of 3 most common malignancies in Korea, the survival rate is not improved since last decades because of delayed diagnosis and limited treatment conditions. Radiation was one of treatment options but the impact on the survival is not remarkable. High dose exposure to target area was suggested for improved effect but low tolerance dose of normal liver tissue is the main limited factor. IMRT is the advanced form of 3DCRT, for focusing high dose on target with minimal dose to surrounding normal tissues. Motion of the tumor by respiration, cardiac pulsation and peristalsis is the main treatment harrier of IMRT for treatment of hepatoma patients. Development of QA technique for acceptable geometrical uncertainties and dose error on target volume is essential for IMRT in clinical treatment but proper QA technique is not yet developed. This study compared the verification film dosimetry with measured dose in phantom and calculated dose in planning computer on exactly same conditions of patient treatments. Within 3% dose differences between 3 groups were confirmed. We suggest that our verification QA technique is easy, economic, iterative and acceptable in clinical application for advanced hepatoma patients.

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.
