  • This investigation was undertaken to study the effects of oral administration (3 weeks) of Collybia confluens mycelial powder (CCMP) produced by a submerged culture on plasma glucose and other biochemical parameters in streptozotocin (STZ)-induced diabetic rats. Antidiabetic and hypolipidemic effects were proportionally increased with the increasing concentration of the CCMP for oral administration. The CCMP, at the dose of 400 mg/kg BW, substantially reduced the plasma glucose level by as much as 33.1 % as compared to the STZ-induced diabetic rats group. It also lowered the plasma total cholesterol, triglyceride, and low density lipoprotein (LDL) cholesterol by 22.9%, 19.9%, and 37.3%, respectively. The levels of total cholesterol and triglyceride in liver were reduced to the extent of by 13.5% and 18.8%, and the activity of alanine transaminase (ALT) and aspartate transaminase (AST) was decreased by 48.8% and 37.2%, respectively, under the influence of CCMP. The general components of CCMP were found to contain 26.18% carbohydrate, 3.67% crude ash, 4.02% crude fat, 22.55% crude protein, and 43.58% dietary fiber. The amino acid composition of the CCMP was also analyzed in detail.

  • In this study we manufactured mulberry fruit tea(MFT) to be used as an anti-inflammatory agent. Here, MFT was consumed by thirty middle-aged women with symptoms of rheumatoid arthritis for 4 weeks. The anthropometric measurements and serum inflammatory factors were measured before and after consumption of the MFT. For the anthropometric measurements, BMI and body fat decreased after 4 weeks of tea consumption although there were no significant differences. The serum inflammatory factors(uric acid and homocysteine) as well as serum amino transferase activity(aspartate trans-aminase and alanine transaminase) showed a decreasing trend. In addition, serum carbon reactive protein(CRP) decreased significantly decreased after MFT consumption 4 weeks. It's concluded that this MFT is helpful to for rheumatyroid arthritis patients in order to decrease serum inflammatory factors such as CRP.

  • Objective: The goal of this study was to investigate the effects of dietary standard ileal digestible (SID) valine:lysine ratios on performance, intestinal morphology, amino acids of liver and muscle, plasma indices and mRNA expression of branched-chain amino acid (BCAA) metabolism enzymes. Methods: A total of 144 crossbred pigs (Duroc${\times}$Landrace${\times}$Large White) weaned at $28{\pm}4days$ of age ($8.79{\pm}0.02kg$ body weight) were randomly allotted to 1 of 4 diets formulated to provide SID valine:lysine ratios of 50%, 60%, 70%, or 80%. Each diet was fed to 6 pens of pigs with 6 pigs per pen (3 gilts and 3 barrows) for 28 days. Results: Average daily gain increased quadratically (p<0.05), the villous height of the duodenum, jejunum and ileum increased linearly (p<0.05) as the SID valine:lysine ratio increased. The concentrations of plasma ${\alpha}-keto$ isovaleric and valine increased linearly (p<0.05), plasma aspartate, asparagine and cysteine decreased (p<0.05) as the SID valine:lysine ratio increased. An increase in SID lysine:valine levels increased mRNA expression levels of mitochondrial BCAA transaminase and branched-chain ${\alpha}-keto$ acid dehydrogenase in the longissimus dorsi muscle (p<0.05). Conclusion: Using a quadratic model, a SID valine:lysine ratio of 68% was shown to maximize the growth of weaned pigs which is slightly higher than the level recommended by the National Research Council.

  • This study was performed to investigate the protective effects of acupuncture on the liver in the oxidative stress caused by cadmium accumulation. Sprague-Dawley male($150{\pm}30g$) rats were stabilized for a week and divided into 5 groups which is normal, control, $LR_3$ acupuncture, $BL_{23}$ acupuncture and sham acupuncture group. For three days experimental groups were received oral doses of cadmium 2 mg/kg twice a day. Acupuncture was given bilaterally at each point 10 times for two weeks. The depth of stimulation was 1 mm at right angles and torsion of acupuncture was produced 2 times per second for 1 minutes. The liver was shipped off and taken weight at the last day of two weeks, and hepatic functions was confirmed through alanine transaminase(ALT) and aspartate amino-transferase(AST). We measured reactive oxygen species of serum, liver and kidney, and compared expression levels of superoxide dismutase(SOD), catalase, glutathione peroxidase(Gpx), nuclear factor erythroid derived 2-related factor 2(Nrf-2), heme oxygenase-1(HO-1), nuclear factor-${\kappa}B$ (NF-${\kappa}B$), cyclooxygenase-2(COX-2), inducible nitric oxide synthase(iNOS), Bax and Cytochrome c. $BL_{23}$ acupuncture group significantly increased liver weight and decreased ALT compared to control group. For the oxidative stress, $LR_3$ acupuncture group significantly reduced reactive oxygen species, and $BL_{23}$ acupuncture group significantly reduced reactive oxygen species and inflammation-related protein compared to control group. But $LR_3$ acupuncture group and $BL_{23}$ acupuncture group didn't significantly reduce apoptosis-related protein. Therefore $LR_3$ and $BL_{23}$ acupuncture showed the effects of antioxidant and anti-inflammatory, especially $BL_{23}$ acupuncture was more effective than $LR_3$ acupuncture on the protection of liver in the oxidative stress.
