This investigation was aimed at the study of the antidiabetic activity and effect on hepatic glutathione metabolism of polysaccharide from Trichosanthes kirilowii in hyperglycemic rats with aboxan (175 mg/Kg, i.p.). As the results, the polysaccharide inhibited the increase of blood glucose, triglyceride level and lactate dehydrogenase activity, but cholesterol not changed. And it increased protein bound-SH, nonprotein bound-SH, glutathione level and inhibited the decrease of glutathione S-transferase.

The responses of whole body protein and glucose kinetics and of nitrogen (N) metabolism to non-protein energy intake (NPEI) were determined using an isotope dilution approach and measurement of N balance in three adult male goats. The diets containing 1.0, 1.5 and 2.0 times ME maintenance requirement, with fixed intake of CP (1.5 times maintenance) and percentage of hay (33%), were fed twice daily for each 21 d experimental period. After an adaptation period of 11 d, N balance was determined over 3 d. On day 17, whole body protein synthesis (WBPS) and glucose irreversible loss rate (ILR) were determined during the absorptive state by a primed-continuous infusion of [$^2H_5$]phenylalanine, [$^2H_2$]tyrosine, [$^2H_4$]tyrosine and [$^{13}C_6$]glucose, with simultaneous measurements of plasma concentrations of metabolites and insulin. Ruminal characteristics were also measured at 6 h after feeding over 3 d. Nitrogen retention tended to increase (p<0.10) with increasing NPEI, although digestible N decreased linearly (p<0.05). Increasing NPEI decreased (p<0.01) ammonia N concentration, but increased acetate (p<0.05) and propionate (p<0.05) concentrations in the rumen. Despite decreased plasma urea N concentration (p<0.01), increased plasma tyrosine concentration (p<0.05), and trends toward increased plasma total amino N (p<0.10) and phenylalanine concentrations (p<0.10) were found in response to increasing NPEI. Increasing NPEI increased ILR of both glucose (p<0.01) and phenylalanine (p<0.05), but did not affect ($p{\geq}0.10$) that of tyrosine. Whole body protein synthesis increased (p<0.05) in response to increasing NPEI, resulting from increased utilization rate for protein synthesis (p<0.05) and unchanged hydroxylation rate of phenylalanine ($p{\geq}0.10$). These results suggest that increasing NPEI may enhance WBPS and glucose turnover at the absorptive state and improve the efficiency of digestible N retention in goats, with possibly decreased ammonia and increased amino acid absorption. In addition, simultaneous increases in WBPS and glucose ILR suggest stimulatory effect of glucose availability on WBPS, especially when sufficient amino acid is supplied.

사람의 섬유아세포인 GM10을 사용하여 glucose의 배양조건에 다른 물질대사 및 IGFBP-3 발현을 살펴본 결과, glucose 농도에 따른 glucose 소비와 triglyceride 축적 수준은 고농도 glucose 배양 조건에서 증가한 반면, 총 단백질 함량은 고농도 glucose배양 조건에서 시간의 경과에 따라 감소하였다. 또한 고농도 glucose 배양 조건에서 5일 동안 배양한 세포 배양액내의 유리아미노산 함량은 저농도보다 고농도 glucose 배양 조건에서 높게 나타났다. IGFBP-3 단백질 수준과 mRNA수준은 저농도 glucose배양 조건에서 증가하였으나, IGFBP-3 단백질 분해효소에 따른 영향은 없었다. 이상의 결과에서 glucose 배양조건에 따른 물질대사는 부분적으로 세포를 이용한 당뇨병 모델 실험에서 in vivo와 같은 결과를 얻지 못하였지만, IGFs와 같은 세포 성장인자에 대한 연구를 통해 세포수준의 당뇨병 모델화가 가능하다고 여겨진다.

Effects of newly developed functional rice grains Goami (high-amylose rice) and Nokwon (green-kerneled rice) on the glucose metabolism and antioxidative defense system in C57BL/6N mice under high fat diet condition were investigated. Animals were randomly divided into five groups (n = 8) and given experimental diets for eight weeks: normal control diet (NC), high fat diet (HF), and high fat diet supplemented with white rice (HF-WR), Goami rice (HF-GR), and Nokwon rice (HF-NR). At the end of the experimental period, the HF group exhibited markedly higher blood glucose level, insulin concentration, plasma lipid peroxidation and lower hepatic glycogen concentration than that exhibited by NC group. However, diet supplementation of Goami and Nokwon suppressed the high fat diet-induced hyperglycemia and oxidative stress through inhibition of the glucose-regulating enzymes and enhancement of the antioxidant enzymes activities. The results illustrate that the new functional rice Goami and Nokwon may be useful in the development of functional foods with preventive effect against high fat diet-induced hyperglycemia and oxidative stress.

The purpose of this study was to investigate the effect of dietary zinc on the carbohydrate metabolism and the serum content of magnesium and chromium in rats fed normal diet. Animals were divided into three groups by different dietary zinc levels which were low(15ppm), normal(30ppm) or high(60ppm). Serum glucose and Insulin concentrations were assessed by the glucose method and the radio immuno assay respectively. Serum zinc. magnesium and chromium contents were measured by Indectively Coupled Plasma(ICP). Results of the study were as follows : 1. Feed intake in a zinc deficiency group was significantly higher than that in other group, but the weight gain in high zinc diet group was significantly lower than in other groups. 2. There were no significant differences in liver, kidney and spleen weight. 3. Serum glucose, insulin and zinc concentrations were not significantly different among different dietary zinc groups, However serum magnesium and chromium concentrations were significantly decreased as the level of dietary zinc was increased.

Objectives : This study was performed to investigate the effects of Rhizoma Arisaematis water extract on lipid and glucose metabolism and histochemical change of obese rats. Methods and materials : 10 rats were divided into normal, control and RA (Rhizoma Arisaematis) groups. We fed the control group a high-fat diet and administered normal saline for 8 weeks. We fed the experimental group of rats a high-fat diet and administered an extract of Rhizoma Arisaematis for 8 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. The groups were examined for effects on blood serum lipids, blood sugar, blood insulin concentration and epididymal fat cells. Results : 1. Serum total cholesterol, triglyceride, HDL-cholesterol and glucose of the RA group decreased compared with those of the control group. These decreased rates were significant(P<0.05). 2. Serum LDL-cholesterol, total lipid, free fatty acid and the average size of epididymal fat cells of the RA group decreased compared with those of the control group. These decreased rates were significant(p<0.01). Conclusions : These results suggest that RA may be used to prevent or cure the obesity iniduced by a high-fat diet.

1. In the tortoise, Amyda japonica, a cold-blooded animal readily available in this country, the role of catecholamines in the regulation of free fatty acids(FFA) metabolism was investigated in both in vivo and in vitro studies. 2. Norepinephrine elevated both FFA and glucose levels in plasma. 3. When $50{\mu}g/kg$ of Epinephrine, Norepinephrine and Isopropylarterenol were administered intravenously, the relative effectiveness of mobilizing FFA was in the descending order of potency-Epinephrine, Norepinephrine and Isopropylarterenol. 4. In order to exclude the 'tonic influence of the endogenous catecholamines', reserpine was given to some animals. Two days after the reserpine-treatment, glucose showed a significant increase over the solely vehicle treated controls, FFA but an insignificant one. Excised auricles from those animals showed a diminished response to tyramine. Seven days after the treatment, however, when the depletion of catecholamines from the tissue stores seemed to be complete, judged from the absence of the response of isolated auricles to tyramine, both FFA and glucose levels were definitely lowered. 5. In in vitro experiments Epinephrine enhanced the FFA-release from the adipose tissue. The effect increased proportionately with the concentration until a maximal effect was attained at a concentration of 1x $10^5$ g/ml. 6. The order of potency in releasing FFA from adipose tissue in vitro was the same as in vitro, i.e., Epinephrine, Norepinephrine and Isopropylarterenol, but the differences were much less marked. 7. Ergotamine exerted no lipolytic action, but inhibited the lipolytic effect ef Epinephrine significantly. 8. Nethalide showed a slight lipolytic effect per se but inhibited the Epinephrine-induced lipolysis significantly. 9. Catecholamines play an important role in regulating FFA metabolism in the cold-blooded animal, just as in the warm-blooded animals, and the tortoise, Amyda japonica, may be used in the studies of fat metabolism as well as the rat.

Objective: This study investigated the relationship of anthropometric and metabolic risk factors with seminal and sex steroidal hormone parameters in a screened population of healthy males. Methods: The participants were healthy young men without chronic or congenital diseases. The body composition parameters that we investigated were measured weight, height, and waist circumference (WC), as well as bioelectrical impedance analysis. Semen samples were analyzed for semen volume, sperm concentration, sperm motility and morphology, seminal pH, and liquefaction time. Biochemistry analysis, including glucose and lipid metabolism parameters, was conducted on fasting blood samples. Testicular volume was calculated separately for each testis using ultrasonography. Results: Body mass index exhibited an inverse association with total sperm count. WC showed negative correlations with numerous seminal parameters, including sperm concentration, total sperm count, sperm morphology, and follicle-stimulating hormone levels. The basal metabolic rate was associated with seminal pH, liquefaction time, and sperm motility. WC, fat mass percentage, and triglyceride levels exhibited negative correlations with sex hormone binding globulin. The measures of glucose metabolism were associated with a greater number of seminal parameters than the measures of cholesterol metabolism. C-reactive protein levels were inversely associated with sperm concentration and total sperm count. Conclusion: Anthropometric and metabolic risk factors were found to predict semen quality and alterations in sex steroidal hormone levels.

Metabolism lies at the heart of cell biology. The metabolism of cancer cells is significantly different from that of their normal counterparts during tumorigenesis and progression. Elevated glucose metabolism is one of the hallmarks of cancer cells, even under aerobic conditions. The Warburg effect not only allows cancer cells to meet their high energy demands and supply biological materials for anabolic processes including nucleotide and lipid synthesis, but it also minimizes reactive oxygen species production in mitochondria, thereby providing a growth advantage for tumors. Indeed, the mitochondria also play a more essential role in tumor development. As information about the numorous microRNAs has emerged, the importance of metabolic phenotypes mediated by microRNAs in cancer is being increasingly emphasized. However, the consequences of dysregulation of Warburg effect and mitochondrial metabolism modulated by microRNAs in tumor initiation and progression are still largely unclear.
