[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.

Objectives: This was a double blinded, randomized, placebo-controlled clinical study for evaluation of safety and effective dose finding of Cardiotonic Pills$^{(R)}$ in patients with chest pain and discomfort. Cardiotonic Pills$^{(R)}$ are composed of Salviae Miltiorrhizae Radix (丹蔘), Notoginseng Radix (三七根) and Borneolum (龍腦). Major effects of Salviae Miltiorrhizae Radix and Notoginseng Radix are vasodilatation, sedation and analgesic action. Borneolum has an antibacterial effect, and can stimulate the central nervous system. All of these substances are oriental herbs that have been used for a long time in east Asia. Cardiotonic Pills fi received Investigational New Drug (IND) approval from the Food and Drug Administration (FDA) in the USA and 40 million people in the world take this pill. We performed a phase IV clinical study to confirm its efficacy and safety in patients who have probable cardiogenic or psychogenic chest pain or chest stifling. Methods: This study was planned for a multi-center clinical trial including four university hospitals of oriental medicine in Korea. This was the first time to evaluate the 'planning treatment according to diagnosis (辨證施治)' of chest pain or chest discomfort according to oriental medical guidelines. The patients who were included in this trial were adult volunteers from 20 to 70 years old who had chest pain or chest discomfort more than twice during a recent month, and we received written consent to participate in this study from all of them. After administration of Cardiotonic Pills$^{(R)}$ for 8 weeks, number of occurrences, duration, appearance and degree of chest pain or chest discomfort was observed and degree of symptoms (severity of illness, global improvement) were measured using a patient's global assessment composite scale. Results: In the patient's global assessment scale, the severity of illness of the Cardiotonic Pills$^{(R)}$ group (n=25) was 14/25=0.56 but of the placebo group (n=25) was 7/25=0.28 (p-value=0.0449). This result indicates Cardiotonic Pills$^{(R)}$have a positive effect on the symptoms of chest pain and discomfort. However, the global improvement of the Cardiotonic Pills$^{(R)}$group was 23/25=0.92, and of the placebo group was 22/25=0.88 (p-value=0.6374). The total symptom score of the Cardiotonic Pills$^{(R)}$ group was $1.68\pm20.06$, and of the placebo group was $16.76\pm72.l4$(p-value=0.2285). The number of symptom events of the Cardiotonic Pills$^{(R)}$ group was $72\pm29.78$, and of the placebo group (n=25) was $10.80\pm38.42$ (p­value=0.3660). We could not find any effects on the other factors examined besides the severity of illness, beyond the difference of standard deviations. Conclusions: Cardiotonic Pills$^{(R)}$ significantly reduced chest pain and chest discomfort in patients. Therefore, we expect that Cardiotonic Pills$^{(R)}$ will be helpful for patients with chest pain and chest discomfort not only caused by heart disease but also by other diseases.

BACKGROUND/OBJECTIVES: Arterial stiffness and endothelial dysfunction are 2 of the independent predictors for cardiovascular disease, while Acanthopanax senticosus Harms (ASH) is a traditional medicinal plant that can improve cardiovascular health. This study aimed to investigate the efficacy of the fruit of ASH on vascular function in apparently healthy subjects. SUBJECTS/METHODS: A 12-week, randomized, double-blind, placebo-controlled design, consisting of healthy adults with at least 2 of the following 3 conditions: borderline high blood pressure (BP; 120 mmHg ≤ systolic BP ≤ 160 mmHg or 80 mmHg ≤ diastolic BP ≤ 100 mmHg), smoking (≥10 cigarettes/day), and borderline blood lipid levels (220 ≤ total cholesterol ≤ 240, 130 ≤ low density lipoprotein cholesterol ≤ 165, or 150 ≤ triglyceride ≤ 220 mg/dL). Randomly assigned 76 subjects who received a placebo or 2 doses of ASH fruit (low, 500 mg/day; high, 1,000 mg/day) completed the intervention. Brachial-ankle pulse wave velocity (baPWV), flow-mediated dilation, carotid intima-media thickness, and BP were measured both at baseline and following the 12-week intervention. Endothelial nitric oxide synthase (eNOS) phosphorylation was assessed by western blotting. RESULTS: Compared with the placebo group, the low-dose group showed more significant changes after the 12-week intervention period in terms of systolic BP (0.1 vs. -7.7 mmHg; P = 0.044), baPWV (31.3 vs. -98.7 cm/s; P = 0.007), and the ratio of phospho-eNOS/eNOS (0.8 vs. 1.22; P = 0.037). CONCLUSIONS: These results suggest that ASH fruit extract at 500 mg/day has the potential to improve BP and arterial stiffness via endothelial eNOS activation in healthy adults with smoking and the tendency of having elevated BP or blood lipid parameters.

This study was to investigate the role of complementary and alternative medicine in the prevention and treatment of benign prostatic hyperplasia. For this purpose, a randomized, double-blind, placebo-controlled trial was performed over 12 months on 47 benign prostatic hyperplasia patients with average age of 53.3 years and international prostate symptom score over 8. Subjects received either sweet potato starch (group A, placebo, 320 mg/day), pumpkin seed oil (group B, 320 mg/day), saw palmetto oil (group C, 320 mg/day) or pumpkin seed oil plus saw palmetto oil (group D, each 320 mg/day). International prostate symptom score, quality of life, serum prostate specific antigen, prostate volume and maximal urinary flow rate were measured. In groups B, C and D, the international prostate symptom score were reduced by 3 months. Quality of life score was improved after 6 months in group D, while those of groups B and C were improved after 3 months, compared to the baseline value. Serum prostate specific antigen was reduced only in group D after 3 months, but no difference was observed in prostate volume in all treatment groups. Maximal urinary flow rate were gradually improved in groups B and C, with statistical significance after 6 months in group B and after 12 months in group C. None of the parameters were significantly improved by combined treatment with pumpkin seed oil and saw palmetto oil. From these results, it is suggested that administrations of pumpkin seed oil and saw palmetto oil are clinically safe and may be effective as complementary and alternative medicine treatments for benign prostatic hyperplasia.

PURPOSE: This study's aim was to investigate the effects of an action observational training in subactue stroke patients with moderate impairment. METHODS: 22 participants (men=13, women=9) with hemiparesis were randomly assigned to action observation training group or task-oriented training group. Patients in both group underwent a patient-specific multidisciplinary rehabilitation program. Participants in the action observation group (mean age, $62.78{\pm}9.85$) were asked to watch the video scene, in the knowledge that they would then attempt to perform the same movement task after watching. The control group (mean age, $61.49{\pm}8.64$) practiced the same tasks, without watching the video. To evaluate upper limb function, the upper extremity part of the Fugl-Meyer Assessment upper extremity and the Box and Block Test were used. The modified Barthel index was used to assess ADLs, and the modified Ashworth scale were used to assess spasticity in the upper extremity. RESULTS: The action observational training group exhibited greater changes in the Fugl-Meyer assessment upper extremity (P<0.05; 95% CI, 0.929 - 6.403), the Box and Block test (P<0.05; 95% CI, 0.086 - 5.913), and the modified Barthel index (P<0.01; 95% CI, 2.483 - 12.627) between groups. And the modified Ashworth scale (P>0.05; 95% CI, -0.402 to 0.624) did not show significantly different between groups. CONCLUSION: These findings suggest that action observational training may be more helpful to improve upper-extremity function than physical training only in subactue patients with moderate impairment after stroke.

Background: Tramadol administered epidurally is known to have one-thirtieth the potency of morphine for treatment of pain following abdominal surgery. We designed a prospective, randomized, controlled study to evaluate the analgesic efficacy and safety of combined epidural infusion of bupivacaine and tramadol with 2-day infusor as ompared to bupivacaine and morphine combined epidural infusion. Methods: Sixty healthy women scheduled for Cesarean delivery were assigned randomly in double- blind fashion: Group 1 (n=20) were given a mixture of morphine 10 mg(1 ml), 0.5% bupivacaine 40 ml and normal saline(NS) 40 ml; Group 2(n=20) a mixture of tramadol 300 mg(6 ml), 0.5% bupivacaine 40 ml and NS 54 ml; Group 3(n=20) or a mixture of tramadol 500 mg(10 ml), 0.5% bupivacaine 50 ml and NS 50 ml, of continuous dose via epidural route following 1% lidocaine 6 ml as bolus dose for 48 hours postoperatively. We evaluated the analgesic efficacy and side effects of these three groups using visual analogue pain scale (VAPS) and verbal rating scale (VRS). Results: VAPS of group 1 and 3 were lower than group 2, and VAPS of group 1 was lower than group 3(12, 24, 36, 48 hours). VRS of group 1 and 3 were lower than group 2 (12, 24, 36 hours). There were incidences of pruritus was 16 patients in group 1. Conclusions: Tramadol does possess the analgesia effect of morphine, but has the added analgesia following increment. Further research to determine the most effective administration method and reguired dosage of tramadol is further needed.

Dry mouth is easily neglected if not associated with oral diseases. Consequently, xerostomatic patients often use unconventional therapies. In traditional Korean medicine, Korean red ginseng (KRG) has long been used to relieve dry mouth. However, no clinical trials have investigated whether KRG actually has an effect on dry mouth. This study was performed to evaluate the efficacy of KRG for dry mouth. We enrolled 100 volunteers with no obvious oral or salivary gland diseases and divided them into KRG and placebo groups. Each group was divided into six subgroups according to age and gender. The subjects received 6 g/day of KRG or placebo for 8 weeks. The dry mouth visual analog scale (VAS), salivary flow rate, and a dry mouth-related symptom questionnaire were evaluated at baseline and at 4 and 8 weeks. KRG treatment did not show any significant differences for any of the variables. However, KRG improved the dry mouth VAS at 4 weeks and dry mouthrelated symptoms at 8 weeks in women, but not in men. Subgroup analyses revealed that KRG markedly improved the dry mouth VAS in women of menopausal age (40 to 59 years) at 4 and 8 weeks. KRG may have beneficial effects for dry mouth in women, especially those of menopausal age, but not in men. Further investigation in post- and perimenopausal women is required to elaborate on these findings.
