  • This study was performed to investigate the anti-obesity effect of Eisenia bicyclis in mice fed a high-fat diet (HFD). Male C57BL/6J mice were divided into three groups that were fed a normal diet, an HFD, or an HFD supplemented with a 5% powder of Eisenia bicyclis (PEB) for 8 weeks. The PEB group showed lower body weight gains than the HFD group. The PEB group also exhibited reduced body fat mass and adipose cell size in epididymal adipose tissue. The concentrations of serum cholesterol, leptin, and insulin in the PEB group were significantly lower than those in the HFD group. Liver triglyceride content was significantly decreased by PEB supplementation. Furthermore, hematoxylin and eosin staining revealed that PEB supplementation reduced lipid droplet formation in the liver induced by HFD. These results suggest that PEB supplementation reduces body weight gain and fat accumulation in HFD-induced obese mice.

  • Obesity is caused by unbalance of energy intake and expenditure, which results in extra accumulation of adipose tissue. Obesity is directly related to metabolic diseases such as diabetes, hyperlipidemia, fatty liver and so on. To investigate the anti-obesity effects of Scutellariae Radix, 70% EtOH extract and water extract of it were tested by in vitro and in vivo studies of fat accumulation. 3T3-L1 preadipocyte cell line was used in a in vitro study of fat accumulation. After 3T3-L1 cells were induced to differentiate into adipocytes, S. radix extract were added and fat accumulation was measured by oil red O staining. In vivo study showed that weight and epididymal/ retro-peritoneal adipose tissues were significantly reduced in mice fed Scutellariae Radix extract compared with control group. Especially, mice fed Scutellariae Radix extract showed reduced serum triglyceride and glucose levels. When adipose tissues were analyzed by microscope, mean adipocyte size was significantly reduced in Scutellariae Radix extract-fed mice. Therefore, this study showed inhibitory effects of Scutellariae Radix on in vitro and in vivo fat accumulation.

  • 본원에서 신종양으로 근치적 신절제술을 시행하여 신세포암으로 확진된 42예를 대상으로 하였다. CT소견의 분석에 있어 종양의 크기와 종양변연의 분엽성 여부 및 신주위강으로의 신전여부를 중심으로 관찰하였다. 병리학적 소견상 전신병기와는 관계없이 종양병기 I기가 33예(78.5%)였고, 신주위공간으로 신전된 II기가 9예(21.5%) 였다. 대상환자들의 연령분포는 14세에서 72세로 평균 51.9세였고 남자 25명, 여자 17명이었으며 우측 신장암이 22예이고 좌측 신장암이 20예였다. 종양의 크기는 2-15 cm으로 평균 7.4 cm이었고 병기 I기인 경우 2-15 cm으로 평균 6.6 cm이었고 II기는 6-15cm으로 평균 10.3cm이었고 II기 종양이 I기에 비해 상대적으로 크기가 크게 나타났으며 이는 통계적으로 유의하였다(P=0.0031). I기 33예 중 25예는 종양의 경계가 매끈하게 관찰되었고(76%) 분엽성의 경계를 보인 것이 8예(24%), Gerota막의 비후를 보인 것이 7예(21%), 신주위 지방층에 줄음영이 관찰된 것이 14예(42%)였다. 그러나 17예는 매끈한 종양경계를 가지며 Geroat 막의 비후나 신주위 지방층의 줄음영 등의 소견을 보이지 않았다. I기 종양중 Gerota 막의 비후만을 보인 예는 8예, 신주위 지방층의 줄음영만을 보인 예는 14예이고 이 두 가지 소견을 모두 보인 예는 7예(21%)였다. 종양병기 II기 9예 중 매끈한 종양 경계를 보인 것이 3예(34%)이고 분엽성 경계를 보인 것이 6예(66%)였으며 Gerota 막의 비후를 보인 것이 5예(55%)이고, 신주위 지방층의 줄음영은 9예(100%) 전 예에서 관찰되었다. 특히 신주위 지방층의 줄음영은 종양병기 II기가 종양 I기에 비해 통계적으로 유의하게 많았다(P=0.0010). II기 종양 중 Gerota 막의 비후만을 보인 예는 5예, 신주위 지방층의 줄음영만을 보인 예는 9예이고 이 두 가지 소견을 모두 보인 예는 5예(55%)였다. 병기에 따른 종양변연의 분엽성 여부, Gerota 막의 비후 및 신주위 지방층의 줄음영의 세 가지 소견의 중복성도 I기 종양은 한 가지 소견만을 보인 것이 7예(21%)이며 두 가지 소견을 보인 것이 6예(18%), 세 가지 소견을 모두 보인 것은 3예(9%)이고 세 가지 소견이 전혀 관찰되지 않은 경우는 17예(51%)였다. II기 종양 9예 중 한 가지 소견만을 보인 것이 2예(22%)이며 두 가지 소견을 보인 것이 3예(33%), 세 가지 소견을 모두 보인 것이 4예(44%)였고 세 가지 소견 중 한 가지 소견도 보이지 않은 경우는 없었다. 이 중 세 가지 소견을 모두 보인 경우는 종양 I기보다 II기종양이 통계적으로 더 많았다. 종양의 크기, 분엽성 종양경계, Gerota 막의 비후, 신주위 지방층의 줄음영 중 한 가지 소견만으로는 신주위공간으로의 신전을 진단하는 것은 어려우나 여러 가지 소견이 함께 관찰되는 경우 올바른 진단에 도움이 될 것으로 생각한다.

  • Effects of alchohol and fat content in a balanced diet on chemical composition and morphology of liver were investigated in growing rats. Fourth eight male rats of Sprague-Dawley strain weighing about 160g were divided into 4 groups ; high fat diet group, alcohol-administered high fat diet group, low fat diet group and alcohol-administered high fat diet group, low fat diet group and alcohol-administered low fat diet group. High and low fat diets supplied 30% and 12%, respectively, of total calorie intake from fat, and alcohol was given by adding ethanol in drinking waster at 10%. Diets contained adequate amounts of all nutrients required for rats, including lipotrpoic agents(choline and methionine) to minimize effects of factors other than alcohol on liver damage. Ratios of liver weight to body weight were statistically different among groups. Liver/dody weight ratios alcohol-administered rats were significantly higher than those of non-alcohol groups after 6 weeks treatment. Although total lipid and triglyceride per gram liver were increased in alcohol-administered rats, especially low fat diet fed rats, the values were not significantly different. Opticmicroscopical observation revealed increase in cell size and no change in morphology of liver. Examination of hepatocytes by electron microscopy showed that fat droplets were observed in all groups but enlarged in the alcohol-administered low fat diet fed rat. Contents of protein, cholesterol and phospholipid were not affected by alcohol consumption. The level of lipid peroxide was significantly lower in the livers of alcohol-administered rats than in the livers of non-alcohol groups. The results of this study indicate that even moderate alcohol drinking and dietary fat content did not affect any significant change in composition and morphology of liver until 6 week treatment but that even moderate alcohol drinking caused some signs of steatosis of liver.

  • In order to investigate the anti-obesity effects of Gambibang-2(here in after referred to GBB2) on the obese gene and obese inhibitory, C57BL/6 mice were induced by high fat diet. C57BL/6 mice were divided into four groups(normal, high fat diet with control, high fat diet with Reductil(here in after referred to RDT), high fat diet with GBB2 extract) and fed for 8 weeks. And observed that, body weight change, the weight change of the adipocytes in body and liver, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, glucose, leptin change in the serum, the expression of ${\beta}3AR$ and leptin gene in 3T3 cell and primary adipocyte cell, histological analysis of adipose tissue and liver tissue. GBB2 and RDT group showed that the revelation of ${\beta}3AR$ in primary adipose cell and 3T3 cell were increased considerably, and that the revelation of leptin in primary adipose cell and 3T3-L1 cell were decreased considerably. GBB2 and RDT group showed that the body weight were decreased considerably after 7-8 weeks. GBB2 and RDT group showed that the weight of adipocyte and liver were decreased. GBB2 and RDT group showed that the amount of HDL-Cholesterol were increased, the amount of glucose, LDL-Cholesterol and Triglyceride were decreased considerably. GBB2 group showed that the amount of leptin in the serum were decreased. GBB2 and RDT group showed that the size of adipocyte in adipocytes tissue and the adipose vacuoles in liver tissue were decreased. Taking all these observations into account, GBB2 considered to be effective in treating on the obese gene and obese inhibitory. Therefore we have to survey continuously in looking for the effective substance and mechanism in the future.

  • Objectives: The purpose of this study was to investigate the anti-obesity effects of the aqueous extract of Schizandra chinensis (SC) in menopausal mice. Methods: To induce menopausal obesity, female mice were ovariectomized (OVX) and fed a high-fat diet (HFD; 60% fat, 28% carbohydrates, 14% protein) for 12 weeks. The mice were divided into 6 groups (n = 8): NOR (sham-operated and vehicle-treated), HFD+OVX (vehicle-treated), E2 (17-beta estradiol 50 ㎍/kg-treated), SC1 (1 mg/kg SC-treated), SC10 (10 mg/kg SC-treated), and SC100 (100 mg/kg SC-treated). Samples were orally administered for 6 weeks, after which all experimental mice were sacrificed. Body weight, feeding efficiency, white adipose tissue weight, adipocyte diameter, and fat vacuoles in liver were analyzed. Results: By treating with SC extract, the body weight and feeding efficiency of mice were significantly decreased. The weight of visceral fat tissues was decreased in the SC10 and SC100 groups. Histopathology showed that fat cell diameters of white adipose tissue were also decreased in the SC10 and SC100 groups. Additionally, SC extract regenerated the hepatocyte damage and decreased the size and number of follicular adipocytes Conclusion: In summary, these results suggest that SC has inhibitory effects against menopausal obesity. Schizandra chinensis may be a potential alternative for obesity among female menopausal diseases.

  • Effects of kimchi on lipid metabolism and immune function were studied in experiments using 63mals SD rats fed 6 inds of Baechu-kimchi containing diet during 4 weeks. Three kinds of freeze dried kimchi differ in fermentation period (not fermented, 3-, 6-week-fermented at 4$^{\circ}C$) were added at 5%, 10% of the diet containing 15% lard. The levels of serum total lipid and triglyceride and the content of liver total lipid and triglyceride of all kimchi groups were lower than those of a control group. But the levels of serum and liver cholesterol is not affected by kimchi intake. The triglyceride concentration of epididymal fat pad and feces of kimchi groups were higher than those of a control group. The food efficiency ratio, epididymal fat pad weight of 3-, 6-week-fermented kimchi 10% groups were significantly lower than control and not-fermented kimchi groups. Especially 6-week-fermented kimchi groups showed adipocytes, less in number and larger in size than those of other groups. The blastogenesis of spleen lymphocytes to LPS was higher in rats fed fermented kimchi diets than rats fed control and not-fermented kimchi diet. These results suggest that kimchi stimulates lipid mobilization to epididymal fat pad and lipid excretion via feces, so lower serum and liver triglyceride concentration. The fermented kimchi stimulate the proliferation of B cell and lower the lipid accumulation in epididymal fat pad, especially kimchi fermented for 6 weeks at 4$^{\circ}C$ lower the adipose cell number.

  • The aims of this investigation was to examine the anti-obesity effects of oral administration with Mulberry leaves extraction in the high-fat diet induced obesity rats. We investigated the anti-obesity effects of the extract from Mulberry leaves on the progress of high fat diet for 8 weeks. Experimental rats were divided into 5 different experimental groups including an normal group (normal dieat; n=10), control group (high fat diet; n=10), I (Mulberry leaves extraction 100 mg/kg oral administration induced obesity; n=10), II (Mulberry leaves extraction 300 mg/kg oral administration; n=10), and III (Mulberry leaves extraction 500 mg/kg oral administration; n=10). It is to analysis changes in body weight, epididymal fat weight, blood lipid profiles, and fat histological findings. Body weights were significantly increase in control group than normal groups(p<0.05). The level of total cholesterol, LDL-C and TG were significantly lower in experimental groups than control group (p<0.05). In histopathologic finding of fat-tissue around testicle experimental group I and II were more decreased than high fat diet-induced control group in fat cell size. These results suggested that the Mulberry leaves extraction oral administration made the increase of anti-obesity effect in high-fat diet induced obesity rats.

  • The present study was conducted to develop a milk filtering system for decreasing somatic cell count (SCC) in bulk tank milk. The pore sizes of the filter were 0.1, 0.3, 0.4, 0.5 and $0.8{\mu}m$. The rate of SCC reduction of $1^{st}$ grade milk on $0.1{\mu}m$ filter was 76% and significantly higher than other treatments. The rates of SCC reduction for 0.3, 0.4, 0.5 and $0.8{\mu}m$ were 35, 32, 18 and 6.4%, respectively. The effects of the milk filtering system on bacterial count and milk fat content were minimal. The milk flow rates per minute between the filter sizes were similar. But discharge pressures were increased as the pore size of the filter decreased. In conclusion, Considering the rate of SCC reduction, discharge pressure and cost, $0.4{\mu}m$ filter could be recommended.
