Effect of fish oil feeding was investigated on morphological changes of thoracic aora in female rats after bilateral oophorectomy(OVX). Fifty four healthy female rats of Spraque-Dawley strain, were divided into sham group, OVX group and , OVX and fish oil feeding, group. Experimental animals were sacrificed at the end first, eighth week and sixteenth week after operation, thoracic aorta blood sample were collected. The results obtained were as follows ; 1) Total cholesterol and LDL-cholesterol contents in serum were significantly higher in the sham and OVX groups than fish oil feeding group. Serum HDL-cholesterol levels among three exjperimentnal group were lowest in the OVX group. 2) In the sham operation group, as experimental period prologed the endothelial cells were distorted round shape and enlarged, and the subendothelial layer was widened in tunical intima. The elastic lamina were disrupted in tunica group. In the fish oil feeding group, the endothelial cells and subendothelial layer in tunica intima, and the elastic lamina in tunica media were intance. From the present results, it was suggested that fish oil feeding may prevent the atherosclerotic changes in thoracic aorta and serum cholesterol induced by oophhorectomy in the rats.

Objectives: This study was aimed to figure out the effect of Onkyung-tang (OKT) on cold hypersensitivity on feet in female patients. Methods: This study was designed to implement multi-center randomized clinical trial in three korean medical hospitals. The female patients who were enrolled in this study were 112 women who suffered from cold hypersensitivity on feet. They were randomly allocated into OKT group or control group in 1:1 ratio. The primary outcome was change in score of visual analogue scale of hypersensitivity on feet, and the secondary outcomes were thermometer of LU4, PC8, ST32, LR3, visual analogue scale of hypersensitivity on hands, result of cold stress test, and score of World Health Organization Quality of Life-BREF. Results: In both group, the VAS of hypersensitivity on feet and hands was decreased while taking the medicine, and the effect of decreasing the VAS continues for the 4 weeks after the end of medication (p<0.001, 0.003, 0.001). In OKT group, the body temperature difference in lower extremity (ST32-LR3) was steadily decreased at every visit and it was statistically significant(p=0.003, <0.001). On the other hand, in control group, the body temperature difference in lower extremity was decreased only while taking the medicine (p<0.001). Conclusions: OKT significantly reduced discomfort coldness on feet in patients, and the effect of treatment was maintained at least for four weeks after medication.

Fourteen non-descript zebu cattle calves of about 1 year and 6 months age and 111 kg average body weight were used in this experiment. Grazing (5 h daily) animals were supplemented with urea-molasses blocks with and without Yucca, while the control group was without any supplementation i.e. grazing only. The feeding trial continued for a period of 70 days (November to February). At the end of trial three animals per treatment were slaughtered to compare carcass traits. Group no. 1 was fed block with yucca, group no. 2 was fed block without yucca and group no. 3 was on grazing only. Block intake was found to be 724 g/h/d and 1,239 g/h/d for group no. 1 and group no. 2, respectively (p<0.05). Feed efficiency of blocks was found to be 2.71 kg and 4.86 kg for group no. 1 and group no. 2, respectively (p<0.05). Block intake per kg $BW^{0.75}$ was found to be 14.75 and 26.05 gram for group 1 and group 2, respectively (p<0.05). Average daily body weight gain was found to be 267 g/h/d, 255 g/h/d and 169 g/h/d for group 1, 2 and 3, respectively. Carcass traits among the three treatments were found to be statistically similar. Thus urea-molasses blocks supplementation improved body weight gain and addition of yucca in the blocks further improved body weight gain, feed efficiency and economics. Environment (ambient temperature, rainfall, wind and humidity) had no significant effect on three treatments.

Objectives : Recently, numerous studies reported that excessive generation of advanced glycation end products (AGEs) stimulated expression of skin wrinkle related proteins. This study aimed to evaluate inhibits skin wrinkle formation effect of Mori Folium (MF) through decreased AGEs. Methods : To evaluate the skin wrinkle inhibition effect of MF, SD-rats were divided into three groups; normal rats (Nor), AGEs-induced rats (Con), AGEs-induce rats treated with MF at dose of 100mg/kg body weight (MF). To induced AGEs, streptozotocin (50mg/kg) was injected intraperitoneally, and after 3 days, 100mM methyl glyoxal was administered orally for 3 weeks. After the experiment, the animal's dorsal skin tissues and serum were separated and tested. Results : The oral administration of MF suppressed the AGEs level in serum. Also, the AGEs in skin tissues was significantly reduced through treatment of MF compared with control group. Moreover, the expressions of AGEs related proteins such as polyclonal anti-$N^e$-(carboxymethyl) lysine (CML), anti-$N^e$-(carboxyethyl)lysine (CEL), AGE receptors (RAGE) were reduced in MF group compared with the control group in kidney and skin tissues. The matrix metallo proteinase-1 (MMP-1) reduced by MF treatment with the result that collagen type 1 alpha 2 (COL1A2) was improved that reduced by accumulation of AGEs. Conclusion : The evidence of this study indicate that oral administration of MF reduces the levels of AGEs in serum, skin, and kidney tissues. In conclusion, MF inhibit skin wrinkle formation, suggesting the potential of anti-wrinkle material.

Purpose: The aim of this study was to identify the minimally meaningful dosage of inulin leading to a prebiotic effect in Indonesian infants. Methods: In a randomized controlled double-blinded, parallel, 3-arm intervention study, 164 healthy formula-fed infants aged 3 to 5 months first obtained formula-A (without inulin) during a 4-week adaptation period. Subsequently, 142 subjects were subjected to a 4-week feeding period by administering either formula-A (no inulin), formula-B (0.2 g/100 mL inulin) or formula-C (0.4 g/100 mL inulin). The primary outcome parameter was %-bifidobacteria in faecal samples determined using quantitative polymerase chain reaction analyses. Secondary outcome parameters were faecal %-lactobacilli, pH and stool frequency, and consistency. Growth and tolerance/adverse effects were recorded as safety parameters. Results: Typical %-bifidobacteria and %-lactobacilli at the end of the adaptation period in the study population were 14% and 2%, respectively. For faecal pH, significant differences between formula groups A vs. C and A vs. B were found at the end of the intervention period. Testing for differences in faecal %-bifidobacteria and %-lactobacilli between groups was hampered by non-normal data set distributions; no statistically significant differences were obtained. Comparisons within groups revealed that only in formula group C, all the three relevant parameters exhibited a significant effect with an increase in faecal %-bifidobacteria and %-lactobacilli and a decrease in pH. Conclusion: A consistent prebiotic effect along with a decrease in pH and increase in %-bifidobacteria and %-lactobacilli was found only in the group administered 0.4 g inulin/100 mL.

A study was designed to investigate the effectiveness of Korean Red Ginseng (ERG) as an oral agent for erectile dysfunction (EF), which was compared to that of placebo and trazodone. Patients who were believed to have EF of mild or non-organic etiologies, randomized into 3 groups to receive 600 mg KRG 3 times daily (group A), placebo (group B) and 25mg trazodone once a day after evening (group C). All agents were given orally. Ninety patients, composed of 30 in each group, were included and analyzed only when clinical follow-up could be achieved at the end of the study for at least 3 months. There were no significant differences(p>0.05) between each group in mean age (43.7 years), duration of EF (5.8 years), the state of marriage (married : 80 patients) and duration of marriage (18.2 years). In group A, the parameters such as rigidity and tumescence on erection, early detumescence, libido and patient's satisfaction were significantly more effective than that of other group (p<0.05). But there were no significant differences in the parameters such as the frequency of coitus, premature ejaculation and morning erection between 3 groups (p>0.05). The efficacy achieved with KGR (60%) was significantly higher (p<0.05) than that of placebo (30%) and trazodone (30%). There were no significant changes on level of serum testosterone and type of AVS-penogram in group A. No side effect was demonstrated in all patients.

An experiment was designed to assess ractopamine supplementation on growth, meat quality and carcass, and fecal scores of pigs. The 96 crossbred pigs ([Yorkshire× Landrace] × Duroc) had an average body weight of 72.8 ± 2.5 kg. Randomized allocation was followed in the allotment of the pigs according to their body weight into 1 of 2 dietary treatments: 1) CON, basal diet and 2) RAC (ractopamine hydrochloride), CON + 1% ractopamine with 12 replication pens per treatment including equal numbers of barrows (2) and gilts (2) per pen. At the end of the experiment, the lean meat percentage was higher (p < 0.05) for the RAC group compared to the CON group. Dietary ractopamine supplementation did not influence (p > 0.05) the growth performance and fecal score throughout the experimental period. In regard to sensory evaluation, higher (p < 0.05) scores for color and firmness were observed in the RAC group than in the CON group. Drip loss (p < 0.05) was higher in the ractopamine fed diet group compared to the control diet group at day 1. Additionally, longissimus muscle was improved (p < 0.05) in the ractopamine treated diet group than in the control diet group. In conclusion, in the early stage, ractopamine supplementation may not influence the growth performance, but it improves the leanness in the meat of finishing pigs.

Objective: As the number of sarcopenic patients worldwide is increasing, the need for the treatment of sarcopenia is increasing. Ginseng has been reported to be a major herbal supplement. We tested whether red ginseng would be effective for sarcopenia using red ginseng preparation which can be easily obtained locally in Korea. Methods: 30 rats were randomly divided into three groups: the control group (n=10) (Group C), the group with Dexamethasone -induced sarcopenia (n=10) (Group D), and the group to which red ginseng was administered group after induced sarcopenia with Dexamethasone (n=10) (Group DH). Dexamethasone was intraperitoneally administered to group D and group DH for 7 days to make sarcopenic model. After that, the red ginseng tablets prepared by Korea Ginseng Corporation were diluted in distilled water and administered orally to the DH group for 2 weeks. Body weight and grip strength were measured 8 times during the experiment. At the end of the experiment, blood was collected by cardiac puncture. In addition, the tibialis muscle was extracted, a myofibril cross section was measured by immunohistochemical staining and MyHC (myosin heavy chain) was quantified by Western blotting. Results: The ratio of the area on myofibril cross-section showed significant differences after administration of the red ginseng tablet. Conclusions: Red ginseng has a significant effect on the recovery of myofibril cross-section on sarcopenia. This experiment will be helpful for future clinical studies on drug effects in sarcopennia.

The aim of this study was to investigate whether a water extract of L. cladonioides (LC) has an anti-obesity effect in 3T3-L1 cells and obese mice. Treatment of differentiated 3T3-L1 adipocytes with LC caused a significant increase in glycerol release and reduced the protein expression of the adipogenic transcription factors, $PPAR{\gamma}$ and C/$EBP{\alpha}$. In an animal model, obese mice were artificially induced by a high fat diet for 10 weeks. Experimental groups were treated with LC (100 mg/kg/day) by gavage for the next 10 weeks. At the end of experiment, the body weight of the LC group mice was reduced by 14.2% compared to the high fat diet (HFD) group. The treatment also decreased liver (31.0%), epididymal (18.0%) and retroperitoneal (19.3%) adipose tissue, and kidney (6.7%) weights, respectively, compared with those of the HFD group. LC prevented diet-induced increases in the serum level of TC (22.6%), TG (11.6%), and glucose (35.0%), respectively, compared with the HFD group. However, the HDL-C level was higher in the LC group (26.1%) than the HFD group. The results of this study thus suggest that LC suppressed lipid accumulation and expression of adipogenic transcription factors, and increased the amount of glycerol release. LC also indicated an anti-obese and anti-hyperlipidemic effect.

Background: The purpose of this study was to investigate the effect of the combined application of manipulation and stabilization exercises on pain and spinal curvature in patients with chronic back pain. Design: Randomized controlled trial Methods: The research subjects included 24 women in their 40s and 50s who have chronic back pain. The sample was evenly divided into an experimental group, which received the combined application of manipulation and stabilization exercises, and a control group, which received stabilization exercises only. The 30-minute intervention was applied five times a week for eight weeks. A bivariate repeated measures analysis of variances was conducted to identify the differences between the two groups before the experiment, after the fourth week, and at the end of the eight-week experiment. The level of statistical significance was set at.05. This analysis examined the within-group changes and the between-group changes using a paired t-test and an independent t-test, respectively. Results: Changes in pain differed significantly depending on the time of the measurement, the interaction between the time of the measurement and each group, and between the two groups (p<.05). Changes in the curvature of the bones of the neck, the bones of the back, and the lumbar vertebrae differed significantly depending on the time of the measurement and the interaction between the time of the measurement and each group (p<.05). Conclusion: The combined application of manipulation and stabilization exercises demonstrated a positive effect on changes in pain and spinal curvature, and the method is expected to be a useful intervention for reducing pain and improving spinal curvature in patients with back pain.
