Background: Pregabalin has been shown to have analgesic effect in acute pain models. The primary objective was to examine the efficacy a single dose of pregabalin, would have on morphine consumption following lumbar discectomy. Methods: With ethical approval a randomized, placebo-controlled prospective trial was undertaken in 32 patients (ASA I-II, 18-65 years) with radicular low back pain for > 3 months undergoing elective lumbar discectomy. Patients received either oral pregabalin 300 mg (PG Group) or placebo (C Group) one hour before surgery. Pain intensity, the accumulative morphine consumption and adverse effects were recorded for 24 hours following surgery. Functional, psychological and quantitative sensory testing were also assessed. Results: Fourteen patients out of the 32 recruited were randomized to receive pregabalin. Morphine consumption was reduced (absolute difference of 42.3%) between groups with medium effect size. (Mann-Whitney; U =52.5, z-score= 2.84, P = 0.004, r = 0.14). This was not associated with a significant difference in the incidence of adverse effects between the two groups. The median pain intensity (VAS) on movement was not significantly different between groups. Conclusions: A single pre-operative dose of pregabalin (300 mg) did not result in a reduction in pain intensity compared to placebo in this patient cohort but the significant reduction in morphine consumption suggests that a fixed peri-operative dosing regime warrants investigation.

Socheongryong-tang(SCRT) is widely used to treat the common cold. The purpose of this study was to evaluate the efficacy of SCRT on Punghan type(風寒型) and Pungyeol type(風熱型) common cold. 98 registered students with commom colds of recent onset were randomized to the double blind, placebo-controlled study. SCRT extract in capsule, $5.4g(1.8g{\times}3cap)$, orally dissolved 3 times a day. The severity of illness was assessed by the physician, using a 5-point scale on start and finish. In Pungyeol type common cold, no statistically significant differences were detected between the SCRT and placebo groups for any of the measured outcomes. In Punghan type common cold, SCRT significantly reduced rhinorrhea (p=0.034) and nasal stuffiness (p=0.048) compared with placebo. This study shows that SCRT is effective in treating cold symptoms in Punghan type common cold. If patients with cold are able to be administered SCRT according to common cold type, the benefit would be expected to increase.

The Yellow needle crystal was isolated from Atractylis Rhizoma, having mp $124{\sim}126^{\circ}C$(decomp.), the chemical composition $C_{16}H_{21}N_{3}O_{6}$, and its m.w. 251. The pharmacological actions of this alkaloid were studied by various psycopharmacological experiments. 1) In order to see the effect of this Atractylis(=At.) alkaloid on gross general behaviors in mice, a behavioral analysis experiment was adapted. The occurrence number of sleep and lying in At. alkaloidal animals with the doses 10mg/kg or 20mg/kg was increased but the number of jumping, exploration, rearing and defecation was significantly decreased than those of placebo. 2) The effect of the At. alkaloid on unlearned emotional behaviors of mice was studied with an open-field method. The At. alkaloidal groups with the doses 20mg/kg or 30mg/kg showed less often the frequency of locomotion than that of placebo. 3) To know the effect of the At. alkaloid on the learning, a standard water maze experiment and conditioned avoidance response were conducted. As compared to placebo control, the aquisition rate of the maze learning in the alkaloidal mice with the dose of 10mg/kg or 20mg/kg was significantly impaired and the speed of swimming was also signficantly delayed. In the conditioned avoidance response, the extinction performances of the alkaloidal rats with doses of 20mg/kg or 30mg/kg did not differ significantly than that of placebo.

Objective: Physical therapy techniques are required for patients with temporomandibular joint disorder (TMD), but the effects of treatment have not been compared. Therefore, effects of transcutaneous electrical nerve stimulation (TENS) and low level laser (LLL), which are most commonly used interventions, were compared. Design: Randomized controlled trial. Methods: Thirty-six participants with pain in the temporomandibular joint were enrolled, and 12 participants were randomly assigned to either the TENS group, LLL group, or placebo group. Each intervention was performed for a total of 6 sessions for 2 weeks. For the evaluation of the participants, the mouth opening (MO), pressure pain threshold (PPT), and stress were measured at three time periods: baseline, post-test, and follow-up at 2 weeks. Results: Significant interaction between groups according to each evaluation point was found only in PPT-masseter (p<0.05). The evaluation time point at which a significant difference appeared was at the post-test and follow-up at 2 weeks time periods. As a result of the post-test, the LLL group showed a significant improvement compared to the TENS group (p<0.05), and at 2 weeks follow-up, the TENS group showed a significant improvement compared to the placebo group (p<0.05). Conclusions: In this study, an experiment was conducted to compare the treatment effects when TENS, LLL, and placebo were given to patients with TMD. In addition, by quantitatively presenting the effect size of each treatment, this study suggests clinical use of TENS and LLL treatment for TMD.

[Purpose] Eccentric exercise induces a decrease in vascular endothelial function. Curcumin, a major component of turmeric, has potent antioxidant and anti-inflammatory properties that are associated with vascular protective effects. The present study examined the effect of acute supplementation of curcumin on eccentric exercise-induced endothelial dysfunction in healthy young men. [Methods] Fourteen healthy sedentary young men (range, 21-29 years) were assigned to either the curcumin (n = 6) or placebo (n = 8) group. All subjects consumed either curcumin or placebo before exercise, and eccentric exercise of the elbow flexors was performed with their nondominant arm. Before and 60 min after exercise, brachial artery flow-mediated dilation (FMD), as an indicator of endothelial function, was measured in the non-exercised arm. [Results] Brachial artery FMD significantly decreased following eccentric exercise (p < 0.05) in the placebo group, but acute supplementation with curcumin before exercise nullified this change. The change in FMD before and after eccentric exercise between the placebo and curcumin groups was significantly different (p < 0.05). [Conclusion] The present study found that acute curcumin supplementation could attenuate the decrease in endothelial function, as measured by FMD, following eccentric exercise in healthy young men.

Houttuynia Cordata Thunb, well known as "E-Sung Cho" in Korea, has been used for the treatment of herpes simplex, chronic sinusitis and nasal polyps. Recently, some studies reported the antileukemic activity, anticancer activity, adjuvanticity, and antioxidant action of Houttuynia Cordata Thunb. In the present study, the anti-obesity activity of Houttuynia Cordata Thunb was investigated. Middle-aged women were examined over a period of 8 weeks (n=30). Participants were divided into four group: Houttuynia Cordata Thunb Exercise (HCE, n=7), Placebo Exercise (PE, n=8), Houttuynia Cordata Thunb Non Exercise (HCNE, n=8), and Placebo Non Exercise (PNE, n=7). Participants in Houttuynia Cordata Thunb groups were received 4.5 g Houttuynia Cordata Thunb and in placebo groups were received same dose of placebo thrice daily with meals. The result after 8 weeks demonstrated that HCE significant decreased visceral fat than PNE. Our present study provides the evidence that Houttuynia Cordata Thunb intake and exercise performance may reduce visceral fat and further studies with larger numbers of subjects are warranted to conclusively demonstrate effectiveness.

Objectives : The present study was made to evaluate the clinical effectiveness of Saengmaeg-san (生脈散) extract to treat xerostomia in stroke patients. Methods : The study design was a double-blind randomized controlled trial. Subjects were stroke patients with xerostomia. They were allocated to either the Saengmaeg-san (n=12) or placebo group (n=12). Saengmaeg-san extract or a placebo in similar opaque capsules was given three times a day for a week. The improvement of xerostomia was measured by the xerostomia-evaluating questionnaire, developed by the school of dentistry in Seoul National University, before baseline and one week later. Eleven of the Saengmaeg-san group and ten of the placebo group finished the trial and were analyzed. Paired samples t-test and Mann-Whitney test were applied to statistical analysis. Results : On three of the six questions, the Saengmaeg-san group improved significantly. On two of the six questions, the Saengmaeg-san group improved significantly more than the placebo group. On the other questions, the Saengmaeg-san group improved more than the placebo group, although significance was not reached. Conclusions : These results demonstrate that Saengmaeg-san extract is effective for treating xerostomia in stroke patients, and further studies should be conducted to provide more valuable information.

Objective : This study was designed to find out whether NS(normal saline) is able to be constituted as an appropriate control group for HHT(Hwangryunhaedoktang herbal acupuncture) and HP(Homnis Placenta herbal acupuncture). Methods : NS and two herbal acupuncture were inserted into Quchi(LI 11) of the subjects. After 5 minutes the subjects completed a questionnaire rating the intensity of 21 kinds of acupuncture sensation; hurting, penetrating, sharp, aching, intense, spreading, radiating, tingling, pricking, stinging, pulling, heavy, dull, numb, electric, shocking, hot, burning, cool, pulsing, and throbbing. We compared the subjective acupuncture sensation between the two groups. Results : As for HHT seven items of the acupuncture sensation were significantly different from NS. In case of HP just two items were significantly different from NS. Conclusion : We found that NS may be able to be an placebo herbal acupuncture for HP. Further study is needed for the appropriate placebo herbal acupuncture.

Purpose: To evaluate thermal effect and medication compliance of red ginseng extract. Methods: Randomized, double-blind, placebo-controlled, cross-over clinical study was performed. Twenty four healthy, married women aged 30-45 years with FSFI score below 25 were randomly divided into two groups; red ginseng group(N=12) and placebo group(N=12). During the first 6-week period (Study1), each group was dosed with red ginseng or placebo twice a day. Before starting the second 6-week period(Study2), a crossover design was chosen with a 2-week break(Washout period). Interchanging two groups after Washout period, red ginseng and placebo were dosed to each group. The efficacy of thermal effect was measured with subjective warm sensation scale and lower abdomen temperature by Digital Infrared Thermographic imaging(DITI) before and after each 6-week period. A medication compliance was assessed after each 6-week period and the correlation medication compliance between Sasang Constitution and subjective warm sensation was analyzed. Results: Overall 23 participants completed the study. In subjective warm sensation scale, after taking placebo, all participants exhibited an improving trend, but there was no significant difference. In lower abdomen temperature by DITI, statistically significant objective thermal effect of red ginseng was also not shown. A medication compliance was higher in Yin constitution(Taeumin, Soeumin), and showed an upward trend with decreasing subjective warm sensation. But no statistically significant difference was exhibited. Conclusion: Statistically significant thermal effect of red ginseng was not shown in this study. We anticipate if a long-term clinical trial is practiced, significant thermal effect of red ginseng will be shown.

The purpose of this study was to evaluate the clinical efficacy of a standardized special ethanol extract from Gynostemma pentaphyllum as a management for anxiety and stress of normal population. This is a two-arm, parallelgroup, randomized, double blind clinical trial comparing Gynostemma pentaphyllum extract 200 mg bid (GP-EX, n=48) or placebo bid (n=54). The main outcome measures were the decrease in anxiety sensitivity index (ASI), the State version (S-STAI) of the Stait-Trait Anxiety Inventory (STAI) and the Trait version (T-STAT) of the STAI from baseline over a 6 weeks treatment period. In more anxious group (S-STAI50 or ASI19), the anxiety in group with GP-EX was decreased significantly than one in normal population with placebo [S-STAI50: T-STAI = from $57.7{\pm}6.5$ ($mean{\pm}S.D.$) to $46.8{\pm}11.2$ in normal population with GP-EX, p=0.002 vs. from $54.1{\pm}9.9$ to $49.0{\pm}9.6$ in normal population with placebo, p>0.05; ASI19: T-STAI = from $47.2{\pm}12.0$ to $42.4{\pm}11.1$ in normal population with GP-EX, p=0.022 vs. from $48.7{\pm}11.5$ to $46.0{\pm}10.4$ in normal population with placebo, p>0.05]. The most frequently reported adverse reactions considered possibly related to treatment were mild gastrointestinal events. GP-EX is more effective than placebo and is well tolerated as a therapy for anxiety and stress of normal population.
