This study was performed to investigate the effects of vegetable sprout powder on serum and adipose tissue lipid metabolism in rats fed high-fat diet for 4 weeks for induction hyperlipidemic model rat. Weight-matched male Sprague-Dawley rats were assigned to five groups according to dietary fat level (10% or 20% of diet wt.) and mixture of vegetable sprout powder levels (5% or 10% 10% or 20% of diet wt.). Vegetable sprout powder was the mixture of same amounts of dried barley, broccoli, rapeseed, alfalfa, radish, mustard, buckwheat and brussels sprouts. Experimental groups were normal fat diet with 5% cellulose (NF-C), high fat diet without fiber (HF-N), high fat diet with 5% cellulose (HF-C), HF-C diet with 5% vegetable sprout powder (HF-CSL), and HF-C diet with 10% vegetable sprout powder (HF-CSH). The body weight of HF-N group increased 16% compared with the NF-C group, while it was decreased by 15% and 22% for HF-CSL group and HF-CSH group, respectively. Fat mass and fat cell size of adipose tissue were lower in HF-CSL group and HF-CSH group compared with HF-C group, and lower in HF-CSH group compared with HF-CSL group. Serum triglyceride, total cholesterol and LDL-cholesterol contents were markedly decreased by vegetable sprout powder containing diet, while the serum HDL-cholesterol and phospholipid contents were higher in vegetable sprout powder containing diet in a dose-dependent manner. Leptin and insulin levels in serum showed a decrease in HF-CSH group. Significantly increased contents of triglyceride, total cholesterol, LDL-cholesterol, leptin and insulin in the serum of HF-N group were returned to normal or even below normal levels by feeding 10% vegetable sprout powder diet. The increased activities of NADP-malate dehydrogenase (ME), glucose-6-phosphate dehydrogenase (G6PDH) and 6-phosphogluconate dehydrogenase (6PGDH) and lipoprotein lipase (LPL) in adiposetissue by HF-N group were decreased to the activity of normal fat group by feeding vegetable sprout powder in a dose-dependant manner. These results indicate that lipid metabolism in rats fed high-fat diet was suppressed by feeding vegetable sprout powder.

The purpose of this research is to seek SPAIR's reversal time (TI) which satisfies two conditions ; maintaining the suppression ability of fat tissue and simultaneously minimizing the inhomogeneity of fat tissue in T2 high-speed spin echo 3.0T magnetic resonance image (MRI) of the brain, and to compare SPAIR with STIR which is fat-suppression technique. The reversal times (TI) of SPAIR protocol are set to 1/2, 1/3, 1/6 and 1/12 of SPAIR TR (420 msec), namely 210 msec (8 people), 140 msec (26 people), 70 msec (26 people) and 35 msec (18 people) and STIR TI is set with 250 msec (26 people). With these parameter sets, we acquired the axis direction 104 images of the brain. In ROI ($50\;mm^2$) of output image, signal intensities of the fatty tissue, the muscular tissue, and the background were measured and the CNRs of fatty tissue and the muscular tissue were calculated. The inhomogeneity of the fatty tissue is SD/mean, where SD is the standard deviation and 'mean' is a average fatty tissue signal. Consequently, SPAIR TI is determined on either 1/3 or 1/6 of TR (420 ms) ; 140 ms or 70 ms. Because the difference of statistics in fat-suppression ability and inhomogeneity of fatty tissue is very small (p < 0.001), Selecting 140 ms seems to be better choice for the image quality. Meanwhile, Comparing SPAIR (TI : 140 ms) with STIR, the fat-suppression is not able to be considered statistically (p < 0.252), but the image quality is able to be considered statistically (p < 0.01). In conclusion, SPAIR is better than STIR in the image quality.

Purpose : To compare Multi Echo Data Image Combination (MEDIC) and fast SE T2-weighted images with fat saturation (T2FS) to suggest more accurate evaluation of the histologic components of soft-tissue tumors. Materials and Methods : The experimental group included 25 histologic tissues (5 vascular, 4 neural, 4 fibrous, 4 hypercellular, 2 hemorrhagic necroses, 2 cystic, 2 lipoid, 1 myxoid stroma, and 1 thrombus) in 10 patients who had pathologically confirmed schwannoma (n = 3), hemangioma (n = 2), lipoma (n = 1), angiokeratoma (n = 1), synovial sarcoma (n = 1), liposarcoma (n = 1), and malignant fibrous histiocytoma (n = 1). The inhomogeneity values were measured using the standard deviation value (SD) divided by the mean value as SD presents an error amount similar to that of imaging heterogeneity. Results : The inhomogeneity values of 25 histologic components were lower on MEDIC than those on T2FS (p < .001). Conclusion : We conclude that MEDIC is more accurate than T2FS for evaluating the tissue components of soft-tissue tumors using digitalized data because MEDIC images have far lower inhomogeneity.

Enzymatically modified isoquercitrin (EMIQ) is a mixture of quercetin glycodsides consisting of isoquercitrin and its ${\alpha}-glucosylated$ derivatives containing one to seven additional linear glucose moieties. The aim of this study was to assess whether or not EMIQ attenuates high-fat diet (HFD)-induced body weight gain and changes in plasma indices of obesity in mice. Male C57BL/6N mice were fed chow diet, HFD, and HFD containing 1.2% EMIQ for 10 weeks. EMIQ significantly (P<0.05) reduced body weight gain (-21%), total visceral fat-pad weights (-31%), and plasma levels of triglycerides (-17%), total cholesterol (-19%), and free fatty acids (-26%) in HFD-fed mice. EMIQ significantly increased protein kinase A (PKA) expression in the epididymal adipose tissue of HFD-fed mice. Expression of adipogenesis-related genes significantly decreased, whereas expression of fatty acid oxidation-related and thermogenesis-related genes increased in epididymal adipose tissue of EMIQ-fed mice compared with HFD-fed mice. These results suggest that the protective effects of EMIQ against HFD-induced adiposity in mice appear to be associated with PKA-mediated signaling cascades involved in adipogenesis, fatty acid oxidation, and thermogenesis in adipose tissue.

This study was carried out to investigate the effects of Peucedanum japonicum Thunb. (PJT) powder on lipid metabolism and antioxidative activity in rats fed a high-fat/high-cholesterol diet for 4 weeks. Male Sprague-Dawley rats were assigned to four groups: normal diet group (N), high-fat/high-cholesterol group (HFC), high-fat/highcholesterol with 5% PJT powder (HFC-PBL), and high-fat/high-cholesterol with 10% PJT powder (HFC-PBH). Body weight gain and food efficiency ratio (FER) increased in the HFC group, whereas they gradually decreased in the PJT powder-fed groups. Food intake was not significantly different between the experimental groups. Liver and adipose tissue weights of the HFC group were heavier than that of the N group, whereas the groups fed PJT powder showed gradual reduction of tissue weights. Serum alkaline phosphatase (ALP) activity significantly decreased after PJT powder administration. Serum triglyceride level significantly decreased in groups fed PJT powder compared to the HFC group. The serum low density lipoprotein cholesterol (LDL-cholesterol) level of the HFC group increased by 73.70% than that of the N group, whereas serum high density lipoprotein (HDL-cholesterol) tended to decrease in groups fed PJT powder compared to the HFC group. Levels of triglycerides in epididymal and mesenteric adipose tissues, as well as cholesterol levels in liver and adipose tissues were lower in the groups fed 10% PJT powder compared to the HFC group. The liver glutathione (GSH) level increased in the groups fed PJT powder compare to the HFC group. The liver thiobarbituric acid reactive substances (TBARS) content significantly decreased in the groups fed PJT powder compared to the HFC group. These results suggest that PJT powder may improve lipid metabolism in the serum, liver, and adipose tissue and prevent oxidative stress by stimulating antioxidative systems in rats fed a high fat-high cholesterol diet.

To investigate the molecular events of controlling intramuscular fat (or marbling), which is an important factor in the evaluation of beef quality, we performed cDNA microarray analyses using the longissimus dorsi muscle and back fat tissues. For this study, we constructed normalized cDNA libraries: fat tissues in native Korean cattle (displaying 1,211 specific genes), and muscle tissues in native Korean cattle (displaying 1,346 specific genes). A bovine cDNA chip was constructed with 1,680 specific genes, consisting of 760 genes from muscle tissues and 920 genes from fat tissues. The microarray analysis in this experiment showed a number of differentially expressed genes, which compared the longissimus dorsi muscle (Cy5) with back fat tissue (Cy3). Among many specific differentially expressed genes, 12-lipoxygenase (oxidizing esterified fatty acids) and prostaglandin D synthase (differentiation of fibroblasts to adipocytes) are the key candidate enzymes that should be involved in controlling the accumulation of intramuscular fat. In this study, differentially and commonly expressed genes in the muscle and fat tissues of native Korean cattle were found in large numbers, using the hybridization assay. The expression levels of the selected genes were confirmed by semi-quantitative RT-PCR, and the results were similar to those of the cDNA microarray.

배추흰나비의 조직과 발생시기에 따른 발생 특이 큐티클단백질의 질적 분포를 조사하기 위해 전기영동법, western blotting 및 autoradiography 법을 사용하였다. SDS-PAGE에서 유충기에는 4개, 용기에는 3개의 단백질이 발생 특이 큐티클단백질로 확인되었다. 전기영동적 이동도로 보아 유충기의 62 Kd 큐티클단백질은 지방체 표피, 혈림프에 모두 분포하며. 22 Kd, 16 Kd 단백질은 지방체와 표피, 그리고 19 Kd 단백질은 지방체에서 확인되고 있으며, 용기의 37 Kd 단백질은 표피에서. 28 Kd, 27 Kd 단백질은 표피와 지방체에 분포하는 양상을 보이고 있다 면역학적 방법으로 발생 특이 큐티클단백질의 동질성을 조사한 결과 용기의 27 Kd 단백질은 표피와 지방체에서 반응을 나타내며, 유충기의 22 Kd 단백질은 단지 표피에서만 미약하게 이의 동질성을 보여주고 있다 즉, 27 Kd 단백질은 지방체 22 Kd 단백질은 표피에서 기원하고 있어 발생 특이 큐티클단백질의 합성부위는 한 조직에서 기원하는 것이 아니라 각기 상이한 조직으로 부터 생성되는 것으로 사료된다.

The present study was conducted to evaluate inhibition effect of oxidation and discoloration in yellow sea bream, treated with some antioxidants, dried and stored for one month. The effect was observed microscopically from the aspects of distribution and movement of fat, and changes of muscular system. On the initial stage of drying, a part of hypodermic fat was penetrated into intermuscular fissile passing through connective tissue and myocommata, but the rest part was exuded to the out side of surface. The tissues from which the hypodermic fat was removed seemed to be hardned with the gathering of adjacent muscle fibers. The inhibition effect of antioxidants was better in order of Tenon-11, BHA, NDGA from the point of retention of fat and preservation of the muscular tissue.
