  • Purpose: The purpose of this study was to examine the effect of black soybean (CJ-3) testa extracts on lipid profiles in streptozotocin (STZ)-induced diabetic rats. Methods: One control group and four STZ-induced diabetic groups with different doses of black soybean (CJ-3) testa extracts treatment [0 mg/kg (diabetic control, EX), 250 mg/kg (EX-250), 500 mg/kg (EX-500), 1,000 mg/kg (EX-1000)] were orally administered for 4 weeks. Results: All CJ-3 treatment groups had remarkably lower serum triglyceride (TG) levels than that of EX group (p < 0.05) whereas hepatic TG contents did not show any differences. Results from serum total cholesterol (TC) concentrations of EX-250 and EX-1000 groups were decreased compared to EX group (p < 0.05). Furthermore, protein levels of 3-hydroxy-3-methyl-glutaryl-Coenzyme A (HMG-CoA) reductase from the liver decreased in all treatment groups (p < 0.05). However, significant differences were not observed in serum glucose and insulin, and glucose transporter 4 (GLUT-4) protein expression in skeletal muscle tissue. Conclusion: These results suggest that black soybean testa extracts could be useful for improvement of hyperlipidemia and hypercholesteremia in diabetes.

  • To learn more about the productivity of edible meat and its functional properties of spent hen, 60 White Leghorn fowls at 20 month of age were randomly divided into 6 groups, 10 hen for each group, and processed. As the productivity of edible meat, the yield of dressed carcass, giblets, cut-up meat, and breast and leg (thigh and drustick) muscles were determined. The approximate chemical composition, the content of salt-soluble protein, the emulsifying capacity and W.H.C. of breast and leg muscle were measured as the functional properties. The results were summarized as follows. 1. The average live weight of spent hen was 1,576.7g from which the yield of dressed carcass and giblets were 998.9g(63.4%) and 75.3g(4.8%) respectively. It means the yield of ready-to-cook form was 1,074.2g(68.2%) and the inedible byproducts was 502.5g (31.8%). 2. The average, weight of each part of cut-up chicken were: neck 41.0g(4.1%), wings 135.9g (13.6%), breast 276.7g (27.7%), legs 323.6g (42.4%). back 176.1g(17.6%) and the cutting-loss was 45.6g(4.6%). 3. The average weight of total edible muscle from breast and leg was 51.5g(85.86% of breast and leg cut weight) and the percentages based on the carcass and live weights were 51.6% and 32.7%, respectively. 4. The contents of H$_2$O, protein, fat and water-protein ratio of breast muscle were 72.95%, 20.54%, 1.59% and 3.55, respectively and those of leg muscle were 71.9%, 19.12%, 3.96% and 3.76%, respectively. 5. The salt-soluble protein contents of breast and leg muscle were 7.97% and 6.26% and their concentrations based on the total protein content were 38.8% and 32.74%, respectively. 6. The emulsifying capacity of breast and leg muscle was 43.23$m\ell$and 43.23$m\ell$, respectively. 7. The W. H. C- of breast and leg muscle was 54.23% and 52.61%, respectively.

  • The purpose of this study is to verify the difference in health and obesity according to water and coffee intake. The study subject is 900 female college students. Physical fitness factors measured in this study were physical strength(grip strength, back muscle strength), muscle endurance (sit-up), Flexibility(Sit & reach) and cardiopulmonary endurance(harvard step). The factors of body composition (intracellular fluid, extracellular fluid, protein, mineral, body water content, muscle mass, lean body mass, body fat mass) and obesity (BMI, body fat percentage, abdominal fat percentage, obesity) were measured with the Inbody equipment. SPSS program was used for all data analysis. Group differences were verified by two-way ANOVA and one-way ANOVA. The results are as follows. There was no interaction effect between water and coffee intake on health and obesity. Therefore, the difference of the dependent variables according to each independent variable was verified. There was no significant difference in physical fitness according to water intake and coffee intake, but there was a significant difference in body composition (intracellular fluid, protein, minerals, body water, muscle mass and lean body mass). Water drinking group more than 7 cups had significantly higher body composition than the 1-4 cups water drinking group. In the case of coffee, the body composition of the 3 cup intake group was significantly higher than that of the none intake group. Obesity was significantly higher than the none intake and 1-2 cup intake groups. Based on the study results, water intake was not related to obesity, but coffee was related. For further studies, it would be better to consider gender and age differences in drinking various beverages such as water and coffee and that would be used to suggest a desirable way of water intake according to individual characteristics of the better health.

  • The aim was to examine resistance exercise-related genes after 8 weeks of resistance training. Thirty-two male Sprague-Dawley rats were divided into four groups: 4 weeks sedentary (4 wks CON, n=8), 8 weeks sedentary (8 wks CON, n=8), 4 weeks exercise training (4 wks REG, n=8), and 8 weeks exercise training (8 wks REG, n=8). The rats were trained to climb a 1-m vertical incline (85-degree), with weights secured to their tails. They climbed 10 times, 3 days per week, for 8 consecutive weeks. Skeletal muscle was taken from the flexor halucis longus after the exercise training. After separating the total RNA, large-scale gene expression was investigated by beadarray (Illumina RatRef-12 Expression BeadChip) analysis, and qPCR was used to inspect the beadarray data and to analyze the RNA quantitatively. The detection p-value for the genes was p<0.01, the M-value {M=$log_2$(condition)-$log_2$(reference)} was >1.0, and the DiffScore was >20. In total, the expression of 30 genes significantly increased 4 weeks after the exercise training, and the expression of six genes decreased. At 8 weeks, the expression of five genes significantly increased and that of 12 decreased. Several genes are potentially involved in resistance exercise and muscle hypertrophy, including 1) regulation of cell growth (IGFBP1, PLA2G2A, OKL38); 2) myogenesis (CSRP3); 3) tissue regeneration and muscle development (MUSTN1, MYBPH); 4) hypertrophy (CYR61, ATF3, NR4A3); and 5) glucose metabolism (G6PC, PCK1). These results may help to explain previously reported physiological changes of the skeletal muscle and suggest new avenues for further investigation.

  • Most of carotenoprotein complexes have been extracted by using buffered solutions. However, in this study carotenoprotein from the muscle of Blue mussel(Mytilus edulis) was extracted by a detergent such as Triton X-100. It was purified and characterized by $20\%$ (w/v) $(NH_4)_2SO_4$, DEAE-cellulose ion exchange and Sephacryl S-300 gel filtration. The carotenoprotein(${\lambda}_{max}=462nm$) had an approximate M. W. of 372KDa(gel filtration). SDS-PAGE analysis of the carotenoprotein indicated the presence of four polypeptides of 60KDa($23.70\%$), 46.9KDa($9.14\%$), 26KDa($49.14\%$) and 13KDa($18.02\%$). Carotenoprotein denaturated by treatment with SDS to a final concentration of $0.2\%$ (w/v) caused a hypsochromic shift of ${\lambda}_{max}$ from 462nm to 456nm. The carotenoprotein contained lipids as structure units. The amino acid composition of the carotenoprotein contained large essential amino acid amounts of $62.8\%$, and the content of threonine($35.9\%$) was higher than other amino acids, but histidine, methionine and proline were not present. In the carotenoprotein, the major fatty acids were $C_{16:4},\;C_{16:0},\;C_{20:5}\;and\;C_{22:6}$. The percentages of polyunsaturated fatty acids($62.4\%$) were higher compared to other fatty acids(saturated fatty acids $19.6\%$, monounsaturated fatty acids $18.0\%$). Carotenoid was extracted from the carotenoprotein by acetone and it was separated into five different components by preparative TLC(benzene:petroleum ether:acetone=69:17:14). The major components of carotenoid were mytiloxanthin($74.79\%$) and 3,4,3'- trihydroxy-7',8'-didehydro-${\beta}$-carotene($18.26\%$), and they were at least presented as prosthetic groups of carotenoprotein.

  • The surface ultrastructure of metacercariae and adults of Gymnophallokles seoi, the only known gymnophallid infecting humans, was observed by scanning electron microscopy. Metacercariae were ovoid or pyriform in shape and slightly concave ventrally. The oral sucker had two sizes of type I papillae, small and large, encircling its lip. Type I papillae were arranged in a row on both side oi the body. The ventral pit had several type I papillae on its inner surface. The ventral sucker was covered with cobble-stone like cytoplasmic processes and had 6 type I papillae on its lip. The surface of the body was covered with the tegumental spines except for the ventromedian area between the two suckers. The spines at anterior body were digitated into 3-5 points, and their size decreased at posterior one third or the body. Adult worms were rhomboid or ellipsoid in shape and covered with tegumental spines except for the ventromedian area. The shape and distribution of the tegumental spines and sensory papillae were similar to those of metacercariae. However, sensory papillae arranged in a row on the ventral surface of metacercariae were not observed in adults. The ventral pit became larger and more prominent as the fluke grew. It is suggested that the ventral pit function as an additional adhesive organ to the host tissue.

  • This study examined whether the supplementation of Salicornia herbacea L. (SH), a member of the Chenopodiaceae subfamily, affects tissue specific triglyceride (TG) accumulation and the peroxisome proliferator-activated $receptor-{\gamma}$ $coactivator-1{\alpha}$ ($PGC-1{\alpha}$) and peroxisome proliferator-activated $receptor-{\gamma}$ ($PPAR-{\gamma}$) protein expressions of skeletal muscle in rats with a high-fat diet. Sprague-Dawley male rats were randomly divided into three groups: control normal diet group (CD), high-fat diet group (HD), and 5.0% SH supplemented high-fat diet group (SD). The weights of fat tissue of the SD group were reduced by approximately 25%(p<0.01), while the skeletal muscle weight of the SD group increased approximately 5% compared to those in the HD group (p<0.01). The serum and hepatic TG of the SD group decreased approximately 20% compared to those of the HD group (p<0.05). In the protein expression levels in the skeletal muscle, the $PGC-1{\alpha}$ and $PPAR-{\gamma}$ expressions of the SD group were 1.5-folds higher than those of the HD group (p<0.01). From these results, SH supplementation contributes to the improvement of the serum and hepatic TG concentrations, and the $PGC-1{\alpha}$ and $PPAR-{\gamma}$ protein expression levels in the skeletal muscle of fed a high-fat diet. Thus, SH supplementation was effective in reducing fat mass and increasing muscle mass.

  • Background: The purpose of this study was to investigate the effect of Plank exercise on unstable support surfaces on flexibility, abdominal muscle thickness and pain in patients with chronic back pain. Design: Randomized controlled trial. Methods: This study was performed on 16 patients with chronic back pain of ◯◯ military unit. Sixteen subjects were randomly assigned into two groups, an upper extremity trainer group (group I, n=8) and a lower extremity trainer group (group II, n=8). The subjects in group I carried out Flank exercise applying the stability trainer to their upper extremities and ones in group II carried out the same exercise applying the stability trainer to their lower extremities for 4 weeks. In order to ascertain the difference between two groups, flexibility, abdominal muscle thickness and pain were measured before and after the exercise. The flexibility was measured by sit and reach test, the thickness of the abdominal muscle was measured by using ultrasonic imaging equipment, and the pain was measured by the visual analogue scale. A paired t-test was utilized to compare changes in pain, abdominal muscle thickness and flexibility before and after flank exercise on unstable support surfaces. Analysis of Covariance (ANCOVA) was performed for ascertaining the significant differences between groups. The significance level was set by α=.05. Results: 1) The flexibilities of two groups were increased after the exercise (p<0.05). 2) In both groups, the thicknesses of rectus abdominis, external oblique abdominis, internal oblique abdominis, and transverse abdominis were all increased after the exercise (p<0.05). 3) The pains in both groups were decreased after the exercise (p<0.05). 4) In the comparisons of two groups, there were no differences in the flexibility, thickness of external oblique abdominis, internal oblique abdominis and transverse abdominis and pain (p>0.05). Whereas only thickness of Rectus abdominis was larger in the group I than in the group II (p<0.05). Conclusion: Plank exercise on the unstable support surface for 4 weeks resulted in increased flexibility, abdominal muscle thickness and pain reduction in patients with chronic back pain. Therefore, it is considered that performing flank exercise on the unstable supporting surface is suitable for the reduction of the pain in patients with chronic back pain. However, in this study, it is considered that continuous and diverse studies are needed because there was not a large difference between the groups when the upper or lower limbs are provided unstable support surfaces.

  • For the improvement of Gulbi processing, yellow corvenia was salted by 2 different time (5 hours, low salted and 5 days, high salted) and then dried in the sun and stored for 5 and 21 days, respectively. Malonaldehyde contents and fatty acid composition were analyzed during Gulbi processing. The moisture contents of yellow corvenia were significantly decreased during processing procedure. The salt contents were 10 folds higher in 5 day-salted sample than in 5 hour-salted one. The salt contents showed reversed tendency to moisture contents. There was little change in pH during storage. The contents of malonaldehyde in yellow corvenia were increased during Gulbi processing and storage. Its contents were higher in 5 day-salted sample and exterior parts than 5 hour-salted sample and interior parts of Gulbi. The fatty acids composition showed higher oleic acid $(C_{18:1})$, palmitic acid $(C_{16:0})$ and docosahexaenoic acid $(C_{22:6})$ than any other fatty acids in Gulbi. Saturated fatty acids were increased but unsaturated fatty acids were decreased during Gulbi processing. After 21 days storage, unsaturated fatty acids remaining ratio in 5 hour-and 5 day-salted sample were 1.39 and 0.99 respectively. The contents of unsaturated fatty acids were dramatically changed as salt concentration increased during storage than in processing.

  • 초음파기기를 이용한 난포란의 채란 기술은 유전적으로 우수한 수정란의 다량확보가 가능함으로써 가축개량에 널리 응용할 수 있다. 그러나 초음파유도 난포란의 채란은 무엇보다도 회수율과 회수한 난포란의 질적 등급의 개선이 이루어져야 할 것이다. 본 연구는 등지방층두께, 일당증체량, 근내지방도 및 배최장근 단면적에 연관된 DNA marker가 검정된 한우로부터 FSH(FOLLTROPIN-V, Vetrepharm, Canada)를 투여하여 FSH 투여전.후의 포의 발달율과 등급별 회수율을 조사하였다. 공시동물의 발정주기에 관계없이 매주 무처리와 채란 12시간 전에 FSH를 각각 l00mg 과 200mg을 근육 주사하여 난포란의 채취를 유토하였다. 난소내 난포란의 채란은 SONOACE-600형 (Medison CO., 한국) 초음파기기를 사용하여 모니터 상에 검게 나타나는 난포를 17-gauge needle (Cook, Australia) 로써 70mmHg로 유지된 regulated vacuum pump를 이용하여 모두 채란하였으며, 소난포는 손가락 촉지를 이용하여 채란하였다. 난포의 크기는(large : $\geq$6mm, medium : 2-6mm, small $\leq$2mm) 무처리구에서 small(56.6%), medium(33.0%), large follicles(10.4%) 순으로 나타났으며, 전체 난포수는 106(8.2$\pm$3.6개) 였다. FSH 200mg 투여구에서는 medium(47.5%), small(32.5%), large follicles(20.0%) 순으로 나타났으며, 전체난포수는 40(10.0$\pm$2.2개) 였다. FSH l00mg 투여구에서는 medium(45.6%), small(43.5%), large follicles (10.9%) 순으로 나타났으며, 전체 난포는 92(7.7$\pm$2.5개) 였다. FSH 투여전 초음파 image 상으로 관찰한 난포수와 FSH 투여 후 초음파기기와 손가락 촉지를 이용하여 난포의 발달 및 난포란의 채란율은 200mg 투여 구에서는 투여 전에 4.3$\pm$0.6개였으나 투여 후에는 9.3$\pm$2.1개로 증가하였으며, 채란율은 75.0% 였다. l00mg 투여구에서도 투여 전후에 각각 5.3$\pm$1.2개 및 8.2$\pm$2.3개였으며, 채란율은 81.6%였다. 난포란의 채란율은 무처리구에서 88.7%(7.2$\pm$3.9개)로 나타났으며, 회수한 난포란의 등급은 각각 0.0%(GI), 5.3%(GII), 28.T%(GIII), 66.0%(GIV)로 나타났다. FSH 200mg 투여구의 채란율은 87.5%(8.8$\pm$2.6개)로 나타났으며, 등급별회수율은 GI(2.8%), GII(8.6%), GIII(34.3%), GIV(54.3%)으로 나타났다. 뿐만 아니라 FSH 100mg 투여구에서도 회수율은 89.1%(6.8$\pm$5.2개)였으며, 등급별 회수율은 각각 GI(8.5%), GII(13.4%), GIII(43.9%), GIV(34.2%)로 나타났다.
