  • This research was performed to investigate the effect of Codonopsis lanceolata water extracted on the levels of lipid in serum and liver of rats fed high fat diet for 6 weeks. Experimental groups were divided into normal group(NF), high fat diet group(HF), high fat diet and Codonopsis lanceolata water extract treated group(HFW). Codonopsis lanceolata water extract was orally administrated at the level of 0.1ml/100g body weight per day. Body weight gain and feed intake were not significantly different in three groups, but feed efficiency ratio was increased in HF and HFW. The weights of liver, kidney, heart were not significantly different among the groups. The level of serum total lipid was higher in HF than NF, but Codonopsis lanceolata water extract decreased the level of the lipid. The levels of serum triglyceride and total cholesterol were significantly increased in HF, but they were significantly decreased by administration of Codonopsis lanceolata water extract. The levels of serum HDL-cholesterol and phospholipid were slightly increased by Codonopsis lanceolata water extract. Codonopsis lanceolata water extract significantly decreased the levels of liver total lipid, triglyceride and total cholesterol which were increased by high fat diet.

  • The effect of various vegetables commonly consumed by Koreans on the induction of glutathione S-trasferase(GST) activity in mice was assessd. The extract of vegetable dissolved in propylene glycol (5ml/kg body wt.) was administered to ICR female mice 6 to 8 weeks old via gavage during 5 days. The changes of body weight and liver weight of all treated groups were not significantly different compared with control group. Hepatic protein contents of trated groups compared with control group were not significantly different except BHT treated group. The induction of GST activity in liver cytosol of mice was the greatest with broccoli, followed by radish, wild green onion, turnip, and green onion. The induction of GST activity in liver cytosol increased up to 1.5 to 1.8-folds at a dose of 24 g fresh vegetable/mouse. The induction of combination between vegetables was the highest with the combination of broccoli and radish (1.83-fold), followed by that of broccoli and green onion (1.72-fold), and that of broccoli and turnip (1.50-fold).

  • Tenebrio molitor, rich in protein, is used as an alternative protein source. Many studies have evaluated Tenebrio molitor larvae (TML) for anti-obesity effects, fatty liver relief, antithrombosis, and antioxidant effects. In this study, we prepared an experimental diet by adding Tenebrio molitor larvae oil (TMLO) to feed and administered it to adult male ICR mice for six weeks. The study assessed the weight gain of mice, prothrombin time (PT), activated partial thromboplastin time (aPTT), blood coagulation time, and the activities of coagulation factor VII and coagulation factor XII. The weight gain of mice was suppressed in the groups fed with TMLO, indicating a potential anti-obesity effect. The blood coagulation time was delayed in the TMLO-fed groups, as evidenced by amplified PT and aPTT values. Furthermore, the activities of coagulation factor VII and coagulation factor XII were diminished in the TMLO-treated groups, indicating a potential thrombosis relieving effect. The concentrations of thromboxane B2 and serotonin declined in the TMLO-fed groups, signifying potential blood circulation effects. Finally, blood triglyceride and LDL-cholesterol concentrations were reduced in the TMLO-fed groups. In summary, TMLO supplementation may have an inhibitory effect on liver damage and blood clot formation caused by obesity.

  • This paper proposed a method to separate a liver into left and right liver lobes for simple and exact volumetry of the river graft at abdominal MDCT(Multi-Detector Computed Tomography) image before the living donor liver transplantation. A medical team can evaluate an accurate river graft with minimized interaction between the team and a system using this algorithm for ensuring donor's and recipient's safe. On the image of segmented liver, 2 points(PMHV: a point in Middle Hepatic Vein and PPV: a point at the beginning of right branch of Portal Vein) are selected to separate a liver into left and right liver lobes. Middle hepatic vein is automatically segmented using PMHV, and the cutting line is decided on the basis of segmented Middle Hepatic Vein. A liver is separated on connecting the cutting line and PPV. The volume and ratio of the river graft are estimated. The volume estimated using 2 points are compared with a manual volume that diagnostic radiologist processed and estimated and the weight measured during surgery to support proof of exact volume. The mean ${\pm}$ standard deviation of the differences between the actual weights and the estimated volumes was $162.38cm^3{\pm}124.39$ in the case of manual segmentation and $107.69cm^3{\pm}97.24$ in the case of 2 points method. The correlation coefficient between the actual weight and the manually estimated volume is 0.79, and the correlation coefficient between the actual weight and the volume estimated using 2 points is 0.87. After selection the 2 points, the time involved in separation a liver into left and right river lobe and volumetry of them is measured for confirmation that the algorithm can be used on real time during surgery. The mean ${\pm}$ standard deviation of the process time is $57.28sec{\pm}32.81$ per 1 data set ($149.17pages{\pm}55.92$).

  • This study was performed to invstigate the effect of dietary protein level and source on cadmium intoxicification in rats. Forty-eight male rats of Sprague-Dawley strain weighing 171$\pm$3g were blocked into 8 groups of 6 animals according to body weigth, and were raised for 30days. Eight experimental diets different with cadmium(0ppm, 400ppm)and protein(15%, 40%) levels and protein source[casien, I.S.P.(isolated soy protein)] were given to animals for 30days. Food intake, weight gain, food efficiency ratio, liver weight, kidney weight and femur weight were lower in cadmium added group, and higher in high protein groups(40% protein) than medium protein groups(15% protein). But, dietary protein source had no influence on them. Cadmium concerntration of liver was higher in rats fed casein than I.S.P. groups, and cadmium concentration in intestine was higher in high protein groups. In femur both high protein and I.S.P.diets increased cadmium concentrations. MT concdentrations in liver, kidney and intestine were higher in cadmium added group, and kidney intestine MT concentration were higher in high protein group. Absorption and retention rates of cadmium were lower in rat fed I.S.P. than animal fed casein among medium protein groups and cadmium concentration in blood and liver of I.S.P groups were lower than casein groups. But absorption and retention rates of cadmium were similar in high casein and I.S.P. groups. Renal damage by cadmium administration was not seen in all groups. Absorption rates of zinc and copper competing with cadmium in absorption process were lower in high protein groups than medium protein groups and lower in rats fed I.S.P. than casein. In conclusion, weight gain, F.E.R, and MT concentraion of high protein groups were higher than those of medium protein groups and absorption and retention rates of cadmium were lower in high protein groups. From these results, it was shown that cadmium toxicity was alleviated by high dietary protein. Meanwhile, the effect of dietary source on the cadmium toxicity was different with protein level. In medium protein groups absorption and retention rates of cadmium were much lower in rats fed I.S.P. than casein. In high protein groups, cadmium toxicity was not influenced by protein source and absorption and retention rates of cadmium were not different between casein and I.S.P. groups.

  • This study was performed to investigate the effect of chongkukjang intake on lipid metabolism and liver function in ethanol consumed rats. Twenty one Sprague-Dawley male rats aging 4 weeks old were used as experimental animals, which were divided into three dietary groups; casein diet(CA), soybean diet(SB) and chongkukjang diet(CJ). Alcohol was consumed with water as 25%(v/v) ethanol solution. After 4 weeks of experimental period, rats were sacrificed to get blood and liver samples for analysis of lipids, lipid peroxides, antioxidative enzymes and biochemical indices of liver function. The mean body weight, food intake and liver index were not significantly different among three groups. Serum level of total lipid, triglyceride and total cholesterol of chongkukjang diet group was the lowest among three groups although the difference was not significant. HDL-cholesterol level was significantly(p<0.05) higher in chongkukjang diet group than that of casein diet group. LDL-cholesterol level of chongkukjang and soybean diet group was significantly(p<0.05) lower than that of casein diet group respectively. Liver TBARS of chongkukjang and soybean diet group was significantly(p<0.05) lower than that of casein diet group respectively. The superoxide dismutase activity of chongkukjang diet group was significantly(p<0.05) higher than that of casein diet group. Catalase activity was not significantly different among three groups. As indices of liver function, glutamic oxaloacetic transminase(GOT), glutamic pyruvic transminase(GPT), $\gamma$-glutamyl transpeptidase($\gamma$-GTP) and lactate dehydrogenase(LDH) were not significantly different among three groups. Serum alcohol concentration and activities of alcohol dehydrogenase(ADH) and aldehyde dehydrogenase(ALDH) were not significantly different among three groups. The chongkukjang diet seems to give a beneficial effect for improving lipid metabolism by increasing HDL-cholesterol level and SOD activity while reducing liver TBARS level. However, effect on liver function has to be investigated further.

  • We demonstrated that Acanthopanax senticosus fermentation products (FM-5111 and FM-5131) administered to rats functionally protect against DL-ethionine-induced and ethanol-induced fatty liver models. In DL-ethionine-induced fatty liver models, the serum concentrations of aspartate aminotransferase (AST), as well as liver concentrations of triglyceride and total lipid against the control decreased in FM-5111 and FM-5131 treated rats. In ethanol-induced fatty liver models, FM-5111 and FM-5131 treated rats showed a decrease in the liver concentrations of triglyceride and total lipid in ethanol-induced fatty liver models. There were no significant differences in the serum concentrations of AST and alanine aminotransferase in FM-5111 and FM-5131 treated rats. Additionally, FM-5111-, or FM-5131-treated rats showed no significant differences in the body weight gain between the control. These results indicate that Acanthopanax senticosus fermentation products might have protective effects against DL-ethionine-induced and ethanol-induced fatty liver models.

  • Hepatic fibrosis refers to the scarring of liver tissue, often resulting from chronic liver injury or inflammation. It is characterized by excessive deposition of extracellular matrix proteins, impairing liver function and potentially progressing to cirrhosis if left untreated. To improve the liver functions, Cordyceps militaris, a species of parasitic fungus known for its medicinal properties, is used in the form of extract. It has been traditionally used in Chinese medicine to boost energy, improve stamina, and support overall health. In this study, we investigated the hepatoprotective effects of Cordyceps militaris extract powder in a liver injury model induced by hepatic fibrosis. Sprague-Dawley (SD) rats were administered Dimethylnitrosamine (DMN) to induce liver injury, and the hepatoprotective effects of Cordyceps militaris extract powder intake were assessed by comparing changes in liver enzyme levels and histological observations. Rats injected with DMN were orally administered Cordyceps militaris extract powder at doses of 0, 125, 250, and 500 mg·kg-1·day-1 for three weeks. After three weeks of treatment, no significant differences were observed in hematological, clinical chemical, organ weight, gross examination, or microscopic examination between the DMN-alone group and the Cordyceps militaris extract powder-treated group. In conclusion, hepatoprotective effects against DMN-induced liver injury in SD rats treated with Cordyceps militaris extract powder were not observed under this study condition.

  • These studies were conducted to investigate the effect of dietary supplemental lincomycin at different food waste supplements on performance and blood components of broiler chicks. Diets were based corn, soybean meal and contained 3,100㎉/kg ME, 21% CP for the rest two weeks. Three levels of dietary lincomycin(LM ; 0, 2.2, 4.4 mg/kg) and food waste(FW : 0, 7.5, 15%) were added for both experiments. Weight gain, feed intake and feed conversion ratio(FCR) were measured for five weeks. Blood components, liver weight and abdominal fat ratio to body weight were examined at the end of experiment. Metabolizable energy of food waste used in formulating diet prior to feeding trials were measured 2,504(Expt 1) and 2,734㎉/kg(Expt 2), respectively. In Expt 1, weight gain of birds fed 4.4mg/kg LM was significantly higher than that of no LM treatment(P〈0.05). It also tended to increase in 7.5% food waste treatment compared to that of control but was not significantly different. FCR of chicks fed 2.2mg/kg LM supplement was significantly improved compared to that of other treatments. However, chicks fed food waste supplements had higher FCR than control as a dietary FW level increased(P〈0.05). There were no significance in blood components of all treatments. Liver to body weight ratio of birds fed 7.5% FW supplements decreased significantly(P〈0.05), but was no consistency in LM treatments. In Expt 2, weight gain of chicks fed 15% FW was not significantly different from the control and 7.5% FW. It tended to increase as dietary supplemental LM increased. It also increased in no LM treatment with 15% FW compared to that of control. However, the birds fed 2.2mg/kg LM with 15% FW exhibited higher weight gain than dther treatments. As FW supplement increased, the feed intake increased significantly(P〈0.05). There were no significance in blood components except serum calcium. Weights of liver were not affected by dietary FW or LM. The results of these experiments indicated that chicks fed 4.4mg/kg LM supplements maximized growth rate of all treatments and improved FCR in 2.2mg/kg LM.
