To examine the combined effects of a high-protein diet and aerobic exercise on body weight and composition and blood lipid profiles in overweight women, 30 young women were recruited and placed into three groups: The high-protein diet and exercise group (HPE), the exercise-only group (EXO) and the control group (CON) (30$\pm$3%, 27$\pm$2%, and 29$\pm$3% body fat, respectively) for an 8-week experimental period. Daily diet included 25% isolated soybean protein (>90% protein, approximately 400 kcal) combined with each subject s usual diet for the HPE group. The exercise program consisted of aerobic-type exercises undertaken >3 times/wk and for>30 min/session at 50-60% of maximal capacity. Physical fitness, body composition, serum total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), triglycerides (TG) and glucose were measured before and after the experiment. Maximal aerobic capacity increased by the end of experiment in both the HPE (from 27.2$\pm$3.5 to 35.l$\pm$5.9 ml/kg/min, p<0.01) and EXO (from 30.3$\pm$5.4 to 33.8$\pm$3.8 mㅣ/kg/min, p<0.05) groups. Percent body fat decreased by 3.3% (p<0.01) in the HPE group and by 1.5% (p<0.05) in the EXO group by the end of the experiment, but not in the CON group. Lower back strength and agility increased only in the HPE group. In the HPE group, TC decreased from 168$\pm$20 to 155$\pm$18 mg/dL and HDL-C increased from 57$\pm$l0 to 61$\pm$9 mg/dL in HPE (p<0.01). But TC and HDL-C did not change in the EXO and CON groups. TG and glucose did not vary among the groups. Although the EXO group showed a similar outcome to that of the HPE group, a favorable change in body composition and blood lipids as well as an improvement in aerobic capacity was more marginal in the latter group.

The effect of topical application with 10, 20 and 30 $\mu\textrm{g}$/ml cortisone and hydrocortisone to the fifth stadium larvae of the silkworm, B. mori on fat body glycogen, protein, total lipids, phospholipids, neutral lipids and haemolymph trehalose and protein has been studied. The fat body glycogen haemolymph trehalose significantly decreased in all the treated groups except in the 10 and 20 $\mu\textrm{g}$/ml treated groups. The fat body protein increased significantly in all the cortisone and hydrocortisone treated groups except in the group treated with 10 $\mu\textrm{g}$ hydrocortisone. Whereas that of haemolymph protein significantly increased in all the groups treated with cortisone and hydrocortisone. The total lipids, phospho1ipids and neutral lipids of the fat body decreased significantly in all the groups treated with cortisone and hydrocortisone when compared with that of carrier control.
Purpose: The purpose of this study was to examine body composition and dietary self-efficacy in nursing students. Methods: The study was a descriptive, correlational study with a convenience sample of 197 female nursing students. This study was conducted from April 1st to May 31th in 2015. SPSS 21.0 program was used for data analysis. Results: The average of body protein was $7.90{\pm}1.17kg$ and normal range was 33%. A BMI's average was $21.02{\pm}2.94kg/m^2$ and 62.9 fell into standard range. The average of dietary self-efficacy of subjects was $3.42{\pm}0.53$. The subjects performed intense physical activities during three or more days had higher body protein (F=5.89, p=.003), body minerals (F=6.15, p=.003) and body-efficacy (F=4.13, p=.017) but remarkably lower body fat (F=4.04, p=.019). There is no noticeable correlation of body composition with dietary self-efficacy. However, it is obvious that each category of body composition had a significant positive correlation. Conclusion: This study demonstrated that students who were inclined to overeat had higher body protein, body minerals, body fat, and BMI. Students performed intense physical activities had high body protein, body minerals, and dietary self-efficacy, whereas they had low body fat. Each entry between the body composition had a significant positive correlation.
Immunoelectron microscopy of storage protein at early stage of seed development showed legumin was firstly accumulated protein in between endoplasmic reticulum (ER) cisternae, and these accumulates were differentiated into protein body (PB) by transformation at later stage. Thin sections of pea cotyledons during the later stages of seed maturation showed three morphologically different types of protein bodies. One of these, presented as rough-surfaced cisternae with terminal dilations, which contained protein deposits and were often found interdigitated between stacks of rough endoplasmic reticulum. Conventional electron microscopy at earlier stages of cotyledon development showed this protein body type initially developed from the rough ER. This transformation of endoplasmic reticulum into a protein body is believed to represent a new pathway of protein body development.
The changes of protein bodies in endosperm cells of both seeds with red seed coat and indehiscent seeds of Panax ginseng C.A. Meyer have been investigated in relation to the embryo development. In the early stage of seeds with red seed coat, spherical spherosomes were distributed in endosperm cells. Protein bodies were formed from vacuoles containing the storage protein. Cell organelles were hardly observed in the cytoplasm. In the late stage of the seed with red seed coat, the endosperm was filled with spherosomes and protein bodies. The protein bodies consisted of amorphous inclusions with high electron density or proteinaceous matrix with even electron density. In the seed of in dehiscence, the protein body in endosperm cells contained globoids and protein crystalloids. The globoid of protein body had a electron dense materials. Umbiliform layer was formed between embryo and endosperm. The deformation patterns of endosperm cell wall and the cellulose microfibril were observed in endosperm cells near the umbiliform layer. Umbiliform layer consisted of lipid body and autolyzed cell debris. The protein body of endosperm cell near the umbiliform layer showed various degenerative patterns, and so electron density of proteinaceous matrix was gradually decreased.reased.
The effect of various dietary protein levels on growth and body composition of young common carp raised from 56 g to 170 g in recirculating system was investigated for 15 weeks when they were fed to visual satiety three times daily. Five experiemtal diets were formulated to contain 40, 35, 30, 25 and 21% protein levels and 3.56, 3.59. 3.63, 3.66 and 3.69 kcal/g diet GE levels respectively. Mean survival rates of the fish fed the 40, 35, 30 and 25% protein diets were not different but sig-nificantly higher than that of the fish fed the 40, 35, 30 and 25% protein diets were not different but sig-nificantly higher than that of o the fish fed the 21% protein diet(P<0.05) Weight gain (g/tank) of common carp fed the 30% protein diet was the best. However weight gain of the fish fed the 25, 30, 35 and 40% protein diets were not different but significantly better than that of the fish fed the 21% protein diet. Feed efficiency ratio of the 21% protein diet was significantly lower (P<0.05) than for other groups of diets which were not different among them. Protein efficiency ratio for the 21% protein diet was significantly lower (P<0.05) than for other groups of diets which were not different among them(P>0.05) Dietary protein level had no effect on hemoglobin content in the fish(P>0.05) Crude protein contents of whole body of the fish fed the 35 and 40% protein diets were significantly higher than that of the fish fed the 21$$\mid$% or 25% protein diet(P<0.05) Body crude lipid contents of the fish fed the 21 and 25% protein diets were significantly higher than that of the fish fed the 30% or 35% protein diet. Crude ash contents of the fish fed the 35 and 40% protein diets were significantly higher than that of the fish fed the 21% or 25% protein diet(P<0.05) Moisture content of the fish fed the 35% protein diet was significantly higher than that of the fish fed the 21% protein diet(P<0.05) In considering growth performance of common carp and efficiency of diet dietary protein level could be lowered up to 25% without the reduction of young common carp production in recirculating system.
To study the correlation with increasing body fat mass for the Standard Guideline for Korean Dietary Life, a nationwide, cross-sectional survey was performed with 178 male college students in december 2005. Among the student subjects, 76 were analyzed for body protein mass, body mineral mass, body fat mass, percent body fat, waist-hip ratio(WHR), body mass index(BMI) and obesity degree using Inbody 3.0(Biospace Co, Seoul, Korea). Body protein mass was at a high level of 92.1%, body mineral mass was at a low level of 94.7%. Body fat mass was at a high level of 28.9%, percent body fat was at a high level of 37.3%, WHR was at a high level of 31.6%, and obesity degree was at a high level of 38.2%, BMI was at a high level of 24.3% and BMR was observed at a high level of 41.8%. WHR was correlated with '7. Prepare food proper amount sanitarily.' and obesity degree, while BMl was were correlated with '4. Increase movement and eat proper amount.' positively. BMR was correlated with '6. Enjoy 3 meal a day regularly.' ArmCircle was correlated with '4. Increase movement and eat proper amount.' and fitness score was corrected with '4. Increase movement and eat proper amount', and '8. Enjoy Korean rice food style.' positively. Body protein mass and body mineral mass were negatively correlated with fruit, ArmCircle was positively correlated with fish, obesity degree was positively correlated with soup and BMI and ArmCircle were positively correlated with sweet. '8. Enjoy Korean rice food style.' was negatively significantly correlated with overweight, over percentage body fat, obesity degree > 120 and BMI. Male students were not practicing the Standard Guideline for Korean Dietary Life well with an average score of 37.7%. However, male students who are within the normal range of body composition analysis value have to notice that over range of weight, protein, percentage body fat, WHI and obesity degree was observed above average score of 30%.
Studies on the effects of protein levels on the total sulphur amino acid (TSAA) requirements of chickens were conducted on the starter broilers by feeding four levels of crude protein(16, 18, 20 and 23%) at three levels of TSAA (0.83, 0.93 and 1.03%) and on the grower broilers by feeding three levels of crude protein (16, 18 and 20%) at three levels of TSAA(0.72, 0.79 and 0.86%). The metabolisable energy of the diets was maintained constant at 3,200 kcal/kg and the experiments were carried out for two growing periods: starter (0-3 wk) and grower (3-6 wk). The results showed that there were significant differences in body weight gain, feed intake and feed:gain ratio under different protein levels of the starters. Crude protein, ME and TSAA intake were significantly affected by increasing the CP levels. The TSAA requirement of the starter broilers is recommended at 0.93% and it is not influenced by different protein levels used in the experiment. For the grower period, body weight gain and feed:gain ratio improved significantly at higher protein diets. Birds fed higher protein diet consumed greater quantities of protein. Responses to TSAA supplementation for body weight gain, feed intake and feed:gain ratio were not significant. The present results showed that the TSAA level of 0.79 to 0.86% was required for grower diets and that the protein levels of the diet did not influence the TSAA requirement.
This study was designed to describe the effect of the protein quality at different intake level of protein on the protein metabolism in the whole body of growing pigs with a simulation model. Varying to the protein level in feeds, four simulations were conducted. The feed protein level, represented as proportions of digestible protein to the metabolic energy (DP/ME, g/MJ), were 6-8, 11-13, 17-19, and 23-25 DP/ME, respectively. Two protein quality and six weeks of growth time were used at each simulation. The objective function for the simulations was protein deposition in the whole body, which was calculated from the experimental results. The parameters in the simulation were determined by the parameter estimation technique. The results obtained from the simulation were as follows: The protein synthesis and breakdown rates(g/day) in the whole body was increased with the increase of protein quality only at lower or required level of protein intake. They showed a parallel behavior in the course of growth, irrespective of quality and level of feed protein intake. The simulated protein deposition and protein synthesis showed a linear relationship between them at different protein quality and level. The affinity parameter showed a linear relationship between them at different protein quality and level. The affinity parameter showed that arginine, tryptophan and isoleucine were more efficient in the stimulation ofbody protein synthesis. Lysine and phenylalanine+tyrosine were less efficient. The oxidation parameter showed that histidine, pheyalanine+tyrosine were less efficient. The oxidation parameter showed that histidine, phenyalanine+tyrosine, and methionine+cystine were oxidized in larger magnitude than lysine and threonine. The oxidation parameter of most amino acids increased with the increase of protein intake beyond the requirement level, but not any more at highest protein intake level. Finally it was found that the improvement of feed protein quality at the lower or required level of protein intake increase protein deposition through a parallel increase of protein synthesis and breakdown.
Various kinds of legumes have included as essential foods in Korean diet. However, a little attention have been paid on variety of those beans other than soybean. Main purposes of this study is to evaluate the protein quality of raw and cooked, red mung bean. Eighty male, sprague-Dawely rats weighing 50 gram were devided into 16 groups, five rats each. Casein protein from red and mung bean were used was included to after true digestibility of the protein of legemes. After 4 weeks feeding period animals were sacrificed and following data: all determined food intake, body weight gain, F.E.R., pp.E.R. and weights of liver, kidney heart, spleen, testis, pancreas, skeletal muscles. Food intake, body weight gain, F.E.R., pp.E.R. of casein group were higher than those of experimental groups (red bean, mung bean) body weight gain was increased with protein increment in the diet in all groups. The weight of liver showed significant difference between standard group and experimental group. (red bean, mung bean) The nitro gen content of liver and muscles were increased with level of protein in the diets.
