  • Prader-Willi syndrome (PWS) is a complex multisystem genetic disorder characterized by hypothalamic-pituitary dysfunction. Many features of PWS indicate a deficiency in growth hormone (GH) production, and these findings provide a rationale for GH therapy in PWS. It is possible that rhGH therapy could have beneficial effects in adults with PWS, similar to those in adults with GH deficiency (GHD) of non-syndromic cause. However, there is a paucity of data on the use of GH in adults with PWS. Here, the previous studies about efficacy and safety of rhGH therapy in PWS adults are summarized. Briefly, rhGH therapy in PWS adults may improve body composition, leading to increased lean body mass and decreased fat mass, as well as decreased subcutaneous and visceral adiposity without overall changes in body mass index. There may be at least transient deterioration in glucose homoeostasis in some PWS patients on rhGH therapy, which requires further study. In addition, clinical care guidelines for rhGH therapy in adults with PWS were suggested.

  • Background: Dietary fats can alter the deposition and distribution of body fats in ruminants. The deposition and distribution of body fat play a vital role in the quality of ruminant carcasses and are of great commercial value since they influence the profitability and consumer acceptability of ruminant meat. The current study examined the effects of dietary blend of 80 % canola oil and 20 % palm oil (BCPO) on carcass characteristics, meat yield and accretion of fatty acid (FA) in subcutaneous, omental, perirenal, and mesentery adipose depots and m. supraspinatus (SS) in goats. Methods: Twenty four Boer crossbred bucks (BW $20.54{\pm}0.47kg$) were randomly assigned to diets containing on DM basis 0, 4 and 8 % BCPO, fed for 100 d and harvested. Results: Diet had no effect (P > 0.05) on slaughter weight, dressing percentage, carcass and non-carcass components, meat yield, color, moisture and carotenoid contents and weight of adipose tissues in goats. The proportion of C18:1n-9 and cis-9 trans-11 CLA in the omental, perirenal and SS was higher (P < 0.05) in goats fed 4 and 8 % BCPO compared with the control goats. Dietary BCPO reduced (P < 0.05) the proportion of C14:0 in the omental, perirenal and mesentery depots, C18:0 in the perirenal depot, C16:0 in the SS and C16:1n-7 in the SS, omental and perirenal tissues. Dietary BCPO enhanced the proportion of C18:1 trans-11 Vaccenic and C18:3n-3 in SS and C20:5n-3 in SS and mesentery depot. No significant changes were found in the FA composition of subcutaneous depot. Conclusions: Results indicate that dietary BCPO can be utilized to alter the FA composition of adipose tissues without detrimental effects on carcass characteristics in goats. Nonetheless, dietary BCPO is not an effective repartitioning agent for body fats in goats.

  • The purpose of this study was to examine the most suitable exercise for the elderly women by comparing the changes in body composition and physical function fitness after modern dance, aquarobic and combined exercise programs for the elderly women. The subjects of this study were 47 elderly women in J-do, chosen as MDG(n=13), AEG(n=11), CEG(n=11) and CG(n=12) for participated for 60 minutes/day and three times/wk for 12 weeks. The results of grip strength, chair stand, arm curl, 2 minute step, 244cm up and go was significantly than in the control group. Back scratch was decreased significantly after exercise only in the modern dance group and combined exercise group but there was no change in chair sit and reach. These results suggest that various exercises were found to play a positive role in maintaining and improving fitness for the elderly women. In addition, additional exercise programs are needed to improve flexibility and mobility of joints for the elderly. It is thought that it is important to voluntarily participate in a movement that suits your interests to make it sustainable.

  • [Purpose] The composition of protein supplements, the consumption timing immediately before and after resistance exercise training (RET), and the quantity of protein supplementation may be important factors for the im-provement of muscle mass and function. Although these factors should be considered comprehensively for effective improvement of muscular function in protein supplementation, relatively few studies have focused on this area. Therefore, this study was designed to investigate whether a protein blend supplement before and after resistance exercise for 12 weeks would be effective in increasing muscular function. [Methods] In total, 18 participants were randomly assigned to a placebo (PLA) or protein blend supplement (PRO) group. All subjects followed the same training routine 3 times per week for 12 weeks, taking placebo or protein supplements immediately before and after each exercise session. The protein supplement consisted of 40 g of blend protein, including hydrolyzed whey protein. The RET consisted of lower body (barbell squat, dead lift, seated leg extension, and lying leg curl) and upper body (bench press, barbell rowing, preacher bench biceps curl, and dumbbell shoulder press) exercises. A repetition was defined as three sets of 10-12 times with 80% of one repetition maximum (1RM). [Results] Although the PRO group had a lower protein intake in terms of total food intake than the PLA group, the mean changes in muscle circumference, strength, and exercise volume increased, especially at week 12, compared to the PLA group. [Conclusion] These results suggest that the composition and timing of protein intake are more important than the total amount.

  • Materials for nutrition education to promote nutrition intake and prevent diseases in elderly individuals were developed, nutrition education was provided to 46 elderly females for 12 weeks, and its effects on the body composition, blood profile, and nutritional quality of subjects were qualitatively analyzed. After the education program, the weight of subjects decreased from 56.7 kg to 56.0 kg (p<0.001), their body fat dropped from 20.8 kg to 19.6 kg (p<0.01), their body mass index (BMI) declined from $25.2kg/m^2$ to $24.9kg/m^2$ (p<0.01), and their percentage of body fat decreased significantly (p<0.05). On the other hand, blood sugar showed a significant increase from 131.6 mg/dl to 141.8 mg/dl (p<0.05). Overall, the percentage of nutrition intake rose. In particular, the estimated energy requirement increased from 89.3% to 99.5% (p<0.05). Further, the contrast ratio of recommended intake showed significant increases in protein (p<0.01), phosphorus (p<0.05), vitamin $B_2$ (p<0.05), vitamin $B_6$ (p<0.05), and niacin(p<0.001), and that of adequate intake showed a significant increase in sodium (p<0.05). The nutrient adequacy ratio (NAR) showed a significant increase only in niacin (p<0.05), and the index of nutritional quality (INQ) showed significant increases in protein (p<0.05) and niacin (p<0.001). After the nutrition education program, a qualitative analysis of nutrients consumed by subjects was conducted. The results show improvements across the board except for the deficient intake of calcium and folic acid, suggesting that the nutrition status of subjects changed in a positive direction through the program. The implementation of this program for elderly individuals in a continuous and repetitive manner is expected to facilitate their nutrition management.

  • The present experiment was performed to study whether or not ovariectomized female rats can be used as an animal model to investigate the effects of estrogen on body compositions. Six-month-old, female rats were ovariectomized and the changes in body compositions were evaluated 6 months after surgery. As summarized in Fig. 2, body fat accretion was double in ovariectomized rats compared to shamoperated rats. Muscle weights were not d!fferent, while bone weights were lower in ovx rats than in sham rats when the values were expressed as a per\ulcornercentage of body weight. Results of the present study suggest that these ovariectomized rats can be utilized as an animal model to study the body compositions of postmenopausal obese women and related health problems.

  • Artificially-produced juvenile black sea bream Acanthopagrus schlegeli (total length $8.3{\pm}1.0\;cm$, body weight $11.2{\pm}4.2\;g$) were released in eelgrass, Zostera marina bed and their initial food organism and changes of body compositions were investigated for one month after release. Predation rates in fish sampled on 1st and 3rd days were 79%, increased up to 100% on 7th and 10th days, and then decreased on 30th days as 75%. Major prey organisms was composed of mainly Amphipoda and Gastropoda. Ratio of Amphipoda and Gastropoda in stomach were highest in fish sampled on 15th and 1st days after release, respectively. Crustacea and Algae were maintained about 20% during a sampling period. Visceral weight index (VWI) offish sampled 20th and 30th after release were significantly higher than that of initial. Carcass crude protein and lipid contents of released fish were showed significantly decreasing; however carcass n-3 HUFA composition was showed increasing tendency with the passage of time after release. Eelgrass bed was supposed to be helpful for the released fish to adjust their feeding habits and biochemical metabolism to the natural environment within a short period after release.

  • This experimental study was designed to verify the anti-aging efficacy of Eukmigihwangtang (EMGHT) and Rehmannia Radix, and determine the specific role and actions of Rehmannia Radix. Normal rat (2 months old), aging rat (8 months old), and pathologically induced rat (2 months old, injected 30mg/kg of streptozotocin) are observed to study the aging eliciting factors such as peroxide contents and enzyme activities. The following results were obtained in this study: 1. For the body weight changes, normal group given Rehmannia Radix showed decrease in the body weight compared to the control group, aging group given EMGHT and Rehmannia Radix showed significant decrease in the body weight, and STZ injected group showed suppression to the body weight loss when given EMGHT and Rehmannia Radix. 2. For the content changes in serum lipid peroxide, normal group showed increasing level as the rat gets older. Aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease in the lipid peroxide level compared to the control group. Decrease was more prominant in the group given EMGHT. 3. For the changes in serum hydroxyl radical, normal group did not show significant changes, but aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease in the hydroxyl radical level compared to the control group. Decrease was more prominant in the group given EMGHT. 4. For the changes in serum superoxide dismutase (SOD) activity, normal group did not show significant changes, but aging group given EMGHT and Rehmannia Radix showed significant increase in the SOD activity compared to the control group. STZ injected group given EMGHT and Rehmannia Radix showed significant decrease in the SOD activity compared to the control group. 5. For the content changes in hepatic lipid peroxide, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease in the lipid peroxide level compared to the control group. 6. For the changes in hepatic cytochrome P-450 activity, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease compared to the control group. Cytochrome b5 activity was significantly decreased only in the STZ injected group given EMGHT and Rehmannia Radix. 7. For the changes in hepatic aminopyrine demethylase and aniline hydroxylase activity, aging group given EMGHT and Rehmannia Radix showed significant decrease compared to the control group. STZ injected group given EMGHT and Rehmannia Radix showed significant increase in the aminopyrine demethylase activity, and showed significant decrease in the aniline hydroxylase activity compared to the control group. 8. For the content changes in hepatic protein bound-SH and nonprotein bound-SH, againg group and STZ injected group given EMGHT and Rehmannia Radix showed significant increase compared to the control group. 9. For the content changes in hepatic glutathione level, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant increase compared to the control group. 10. For the changes in hepatic glutathione S-transferase activity, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant increase and decrease, respectively, compared to the control group. 11. For the changes in hepatic glutathione reductase activity, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant increase compared to the control group, while $\gamma$-Glutamylcystein synthetase activity did not show significant changes. 12. For the changes in hepatic superoxide dismutase activity, aging group and STZ injected group given EMGHT and Rehmannia Radix showed significant decrease compared to the control group. From the above results, the antioxidant effects of EMGHT and Rehmannia Radix were proved, as well as the role of Rehmannia Radix, a chief of EMGHT, was examined. In addition, since no change was reconized as the quantity of Rehmannia Radix and the order herbs increased, the reasonableness on EMGHT was proven with respect to its composition and quantity. Thus, the significance of EMGHT could be objectively exmined in terms of its composition and quantity. Considering animals used in the experiment, there were obvious changes in aging rats and pathologically induced rats than in normal rats. Consequently, it was noticeable that EMGHT and Rehmannia Radix were working selectively on the subjects.

  • This study was conducted to evaluate the effects of duck-meat consumption on adult disease risk factors, including body compositions, hematological variables, and serum metabolic and lipid profiles in adult human males. To obtain results, 20 adult males aged 20 to 25 were subjected to a diet of 600 g/day of duck-meat for 4 wk, after which body composition, hematological variables, and serum metabolic and lipid profiles were investigated to determine if there was a relationship between duck-meat consumption and adult disease risk factors. The results revealed that high amounts of duck-meat intake did not negatively alter body indices such as body weight, fat mass, body mass index (BMI), % body fat or waste-to-hip ratio (WHR). Furthermore, there were statistically insignificant changes in the number of blood cells, although this number did increase significantly following intake of duck-meat. Moreover, general decreases in serum metabolic parameters were observed, but none of these changes were significant with the exception of the concentration of blood urea nitrogen (BUN). The serum concentrations of LDL-cholesterol also showed a statistically significant decrease by 5.86%. Therefore, this study suggests that the ingestion of duck-meat not only significantly increased the RBC count but also decreased BUN and LDL-cholesterol concentrations in adult males.
