  • IGF-I is involved in the regulation of growth and differentiation in mammals, but its role as a modulator of growth and metabolism in poultry is poorly understood. And, no studies have so far been reported for the comparison between serum IGF-I concentration and body growth in the egg type or the dual purposes (meat and egg type) chicken including the Korean Native Ogol Chicken (KNOC). Therefore, in order to improve the body growth and meat production of the KNOC, this study was conducted for the identification of the polymorphism of IGF-I gene and for its possible association with both body weight and IGF-I concentration. The RFLP patterns for IGF-I gene were identified by the PstI restriction enzyme. The frequencies of +/+, +/-, and -/- genotype were 16.9%, 51.7%, and 31.4%, respectively. Any statistical significance was not observed in all variations except for sex variation (p<0.01) by covariate quadratic model. The significant effect of the IGF-I genotype on body weight by sex indicates that there are different physiological characteristics in gender. Although the body weights of male KNOCs in most ages were not significant, there was a tendency of KNOCs with +/+ IGF-I genotype to be heavier than those with any other genotypes. But all IGF-I genotypes in female did not influence on body weight. The ANOYA revealed no significant effects of IGF-I genotypes on serum IGF-I concentration but sex effect was highly significant on the IGF-I concentration at 20 and 40 weeks (p<0.01). Although the +/+ genotype, in gender, tended to express a higher IGF-I concentration than the other genotypes at all ages in males, a statistical difference among the genotypes was not found except for 60 weeks (p<0.05). Furthermore, since body weight and IGF-I genotypes are associated, it is possible to improve KNOC to a meat type breed if a continuous selection can be made for the body weight and/or IGF-I traits.

  • Alloxan administration in rats is used as a model for non-insulin dependent diabetes mellitus (NIDDM). NIDDM is a multifactorial disease, characterized by hyperglycemia and lipoprotein abnormalities. In this study, we evaluated the antihyperglycemic and antihyperlipidemic effects of fermented Rhynchosia nulubilis (FRN) through the regulation of glucose uptake in alloxan-induced rats. Fermented R. nulubilis was administered orally for 28 d at 500 mg/kg of body weight. Body weight and food intake were monitored every day. Biochemical parameters were quantified after 4 week. In the diabetic + FRN group, body weight increased significantly and blood glucose concentrations decreased when compared to those of the diabetic group. After 2 hr of administration, the oral glucose tolerance test (OGTT) indicated a significant reduction in the diabetic + FRN group compared to diabetic group. The diabetic + FRN group experienced a significant reduction in total cholesterol, triglycerides, low density lipoprotein, coronary risk factors, and malondialdehyde concentrations, with significantly increased high density lipoprotein compared to those of diabetic group. These results demonstrate that fermented R. nulubilis possesses potent antihyperglycemic and antihyperlipidemic activity in alloxan-induced diabetic rats.

  • The peroxisome proliferator-activated receptor ${\alpha}$ ($PPAR{\alpha}$) is a nuclear transcription factor that plays a central role in lipid and lipoprotein metabolism. To investigate whether swim training improves obesity and lipid metabolism through $PPAR{\alpha}$ activation in female sham-operated (Sham) and ovariectomized (OVX) mice, we measured body weight, visceral adipose tissue mass, serum free fatty acid at 6 weeks as well as the expression of hepatic $PPAR{\alpha}$ target genes involved in fatty acid oxidation. Swim-trained mice had decreased body weight, visceral adipose tissue mass and serum free fatty acid levels compared to high fat diet fed control mice in both female Sham and OVX mice. These reductions were more prominent in OVX than in Sham mice. Swim training significantly increased hepatic mRNA levels of $PPAR{\alpha}$ target genes responsible for mitochondrial fatty acid ${\beta}$-oxidation, such as carnitine palmitoyltransgerase-1 (CPT-1), very long chain acyl-CoA dehydrogenase (VLCAD), and medium chain acyl-CoA dehydrogenase (MCAD) in OVX mice. However, swim trained female Sham mice did not increase hepatic mRNA levels of $PPAR{\alpha}$ target genes responsible for mitochondrial fatty acid ${\beta}$-oxidation compared to Sham control mice. These results indicate that swim training differentially regulates body weight and adipose tissue mass between OVX and Sham mice, at least in part due to differences in liver $PPAR{\alpha}$ activation.

  • Background: Recently, Obesity has become a social problem in all over the world including Korea. Dietary regulation, exercise and behavior modification therapy are used in the treatment of obesity, but until now, there have been many difficulties in treating it. Objectives: To examine in obese pre-menopausal Korean females the short-term efficacy for weight loss of an herbal formula (Slim-diet). Design: A 6-week longituidinal evaluation of a herbal formula (Slim-diet) in 35 pre-menopausal females (baseline age $31.6\;{\pm}\;6.1$) with body mass index > $25kg/m^2$. Body composition was measured using bioimpedence analysis (BIA) and dual energy X-ray absorptiometry (DXA). Anthropometry was done by same observer. Total cholesterol, total lipid, triglyceride, and LDL-cholesterol were measured. Results: Herbal formula (Slim-diet) treatment produced significant loss of weight (P < 0.001), percent of body fat (P < 0.001, both BIA and DXA) and waist circumference (P < 0.001). It also produced significant reduction of total cholesterol and total lipid levels (P < 0.05).

  • Ovariectomy induced hyperphagia was reported in various animal models. It was postulated that hyperphagia resulted in interstinal hypertrophy and hyperplasia. Therefore, this study was performed to compare the food intake and intestinal changes between ovariectomized rats(OVX) and sham operated rats(Sham). Results of this study showed that the food intake and body weight of OVX animal was significantly higher than those of Sham animal. This results confirmed the effect of ovarian hormone on the food intake regulation. Hyperphagia induced by ovariectomy influence the intestinal cell growth and showed hyperplasia determined by protein/DNA ratio. Maltase and alkaline phosphatase activity suggested that the intestinal cell was fully matured in body groups. There were no difference in weight of other organs, such as liver, heart and kindney between two groups.

  • Mice were fed semi-purified diets containing 0, 2, 10 and 25 ppm(mg/kg) deoxynivalenol over 8 weeks and were assessed for effects on bodyweight gain, serum immunolglobulin levels and surface immunoglobulin bearing lymphocyte ratio. 1. The rate of body-weight gain was significantly reduced (p<0.05) at the 10 and 25 ppm of DON, whereas the mice ingesting the diet containing 2 ppm DON was not. 2. IgA in serum immunolglobulin was significantly increased (P<0.05) at the 10 and 25 ppm of DON, but IgG, IgM were decreased, whereas exposure to 2 ppm DON was not change. 3. Concentration of IgA from Peyer's patch of mice fed DON exhibited increased at 10, 25 ppm. 4. Lymphocytes surface marker studies revealed that IgA, IgG and IgM were 2.2%, 0.4% and 1.5% respectively. These results suggest that dietary exposure to DON alters regulation of IgA production

  • Background: The present study investigated the effect of ginseng berry hot water extract (GBx) on blood flow via the regulation of lipid metabolites and blood coagulation in rats fed a high-fat diet (HFD). Methods: Sixty rats were divided into five groups in descending order of body weight. Except for the control group, the other four groups were fed a HFD containing 45% kcal from fat for 11 wk without GBx. GBx groups were then additionally treated by gastric gavage with GBx dissolved in distilled water at 50 (GBx 50) mg/kg, 100 (GBx 100) mg/kg, or 150 (GBx 150) mg/kg body weight for 6 wk along with the HFD. To investigate the effects of GBx on rats fed a HFD, biochemical metabolite, blood coagulation assay, and histological analysis were performed. Results: In the experiments to measure the serum levels of leptin and apolipoprotein B/A, GBx treatment attenuated the HFD-induced increases in these metabolites (p < 0.05). Adiponectin and apolipoprotein E levels in GBx-treated groups were significantly higher than the HFD group. Prothrombin time and activated partial thromboplastin time were increased in all GBx-treated groups. In the GBx-treated groups, the serum levels of thromboxane $A_2$ and serotonin were decreased and concentrations of serum fibrinogen degradation products were increased (p < 0.05). Moreover, histomorphometric dyslipidemia-related atherosclerotic changes were significantly improved by treatment with GBx. Conclusion: These results suggest the possibility that GBx can ameliorate blood flow by decreasing intima-media thickness via the regulation of blood coagulation factors related to lipid metabolites in rats fed a HFD.

  • Euryhaline teleost have extraordinary ability to deal with a wide range of salinity changes. To study the seawater adaptability of rainbow trout Oncorhynchus mykiss (body weight 638±54 g, length 38.6±2 cm) to salinity increase fish were transferred from freshwater to 7, 14, 21, 28 and 32 psu and checked for mortality over 5 days. No mortality was observed in 0-32 psu. In fish transferred to 0-32 psu, blood osmolality was maintained within physiological range. The changes of serum enzyme activities (aspartate transaminase, AST and alanine transaminase, ALT) showed no significant level during experimental period. To explore the underlying molecular physiology of gill and kidney responsible for body fluid regulation, we measured mRNA expression of five genes, Na+/K+/2Cl- cotransporter1 (NKCC1), aquaporin3 (AQP3), cystic fibrosis transmembrane conductance regulator (CFTR), glucocorticoid receptor (GR) and growth hormone receptor (GHR) in response to salt stress. Based on our result, rainbow trout could tolerate gradual transfer up to 32 psu for 5 days without mortality under physiological stress. This study suggests to alleviate osmotic stress to fish, a gradually acclimation to increasing salinity is recommended.
