  • The effects of disulfiram implantation therapy have three components : placebo, pharmacological, and psychological effects, However, considering the fact that there is no reported DER(disulfiram-ethanol reaction) in placebo implanted patients and the absorption of implanted disulfiram is not sufficient to produce DER, the major effect of disulfiram implantation is psychological rather than placebo and pharmacological one, Recently, there have been great efforts to develop a new farm of disulfiram which could exert a real pharmacological effect through the heightened bioavailability, To illustrate several examples, there are copolymer consisting of disulfiram and polymer such as polyethylene glycol and PLGA(polyglycolic-co-L-lactic acid) and depot in which disulfiram is dissolved into saline solution containing 5% w/v carboxymethylcellulose or 0.1% polysorbate 80. On the other hand, there has been a continuous research about Me-DTC, an active metabolite of disulfiram, which inhibit ALDH (acetaldehyde dehydrogenase) more potently even at a smaller amount than disulfiram. In the future. In is hoped to develop a new form of disulfiram with high bioavailability at a small amount.

  • In this study, the skin moisturing effect and stability of cream containing L. cuneata G. Don extract (ethyl acetate fraction) were evaluated. The skin hydrating effect of the cream containing extract was 1020% higher than the placebo cream, and the TWEL of the cream containing extracts was decreased to $7.7g/m^2h$ compared to the control ($10.2g/m^2$) and placebo cream ($8.9g/m^2$). The pH, viscosity, and absorbance were measured under the 4, 25, 37, $45^{\circ}C$ and the sun light during the 12 weeks. The pH change between cream containing extract and placebo cream did not show the significant difference under the 4, 25, 37, $45^{\circ}C$ except for the sun light. Both creams showed high decrease (about 59%) of viscosity at $45^{\circ}C$. However, there was no significant change under other conditions. The absorbance of the cream containing the extract and the placebo cream was decreased similarly at all conditions. This decrease in absorbance was relatively small compared to the decrease of absorbance of the extract in ethanol solution under the sun light (Fig. 7). In addition, any change in color or smell of the cream was not observed during the 12 weeks. Also physical changes as creaming and cohesion were not shown. These results indicate that the cream containing L. cuneata extract has the skin moisturizing effect and is relatively stable. Therefore, it is suggested that the ethyl acetate fraction of L. cuneata extract could be applicable to cosmetics as a new cosmetic material with its antioxidative and antibacterial activities reported previously.

  • The aim of this review was to assess the effectiveness of ginseng as a treatment option for managing menopause symptoms. We searched the literature using ll databases from their inception to 26 September 2012 and included all randomised clinical trials (RCTs) that compared any type of ginseng to a placebo controls in postmenopausal women. The methodological quality of all studies was assessed using a Cochrane risk of bias tool. Four RCTs met our inclusion criteria. Most RCTs had high risk of bias. One RCT showed that Korean red ginseng (KRG) significantly improved sexual arousal and global health compared with placebo. Another RCT reported the superiority of KRG over placebo for treating menopause symptoms on Kupperman's index and menopausal rating score. The third RCT failed to show a significant effect of KRG on hot flash frequency compared to placebo. The fourth RCT found beneficial effects of ginseng compared to placebo on depression and well-being. In conclusion, the evidence on ginseng as an effective treatment for managing menopause symptoms is limited. Most of the RCTs are burdened with a high risk of bias. Thus firm conclusions cannot be drawn. Rigorous studies seem warranted.

  • Yeonkyopaedok-san(YPS) extract is widely used to treat the common cold. The purpose of this study was to evaluate the efficacy of YPS on the common cold. Two hundred Patients with common colds of recent onset were randomized to the double blind, placebo-controlled study. They received 800 mg YPS extract or placebo in capsules, orally dissolved 3 times a day for 7 days. The total symptom score was assessed by the physician, using a 5-point scale on start and finish. Resolution of cold symptoms based on subjective daily symptoms. Total symptom score was significantly decreased in YPS groups in comparison to that in placebo group (p=0.027). Headache (p=0.012), loss of appetite (p=0.037), eyeball discomfort (p=0.002) were more affected. Time to resolution of cold symptoms did not show significant effect (p=0.592). Adverse effects were less in the YPS group than placebo group (2% vs 3%). In this community-based, randomized controlled trial, YPS were effective in treating cold symptoms in college students.

  • The purpose of this systematic review and meta-analysis was to assess the preventive effect of theophylline on acute kidney injury and the ameliorative effect of theophylline on renal function in asphyxiated neonates. A literature search of the PubMed/Medline, Embase, and Cochrane Library databases for information published up to February 2019 was conducted. All studies that reported the incidence rate of acute kidney injury, serum creatinine level, and glomerular filtration rate after the randomized administration of theophylline or placebo were included. In total, eight studies involving 498 neonates were eligible. The incidence rate of acute kidney injury was significantly lower in the theophylline group than in the placebo group (risk ratio [RR]: 0.42, 95% confidence interval [CI]: 0.32-0.55, p < 0.001). The changes in serum creatinine level in the theophylline group were significantly higher than those in the placebo group from the first day of life to 3 and 5 days of age (weighted mean difference [WMD]: -0.51, 95% CI: -0.62 to -0.40, p < 0.001, and WMD: -0.26, 95% CI: -0.34 to -0.18, p < 0.001, respectively). The changes in glomerular filtration rate in the theophylline group were significantly higher than those in the placebo group from the first day of life to 3 days of age and the last day of follow-up (WMD: 12.30, 95% CI: 9.39-15.21, p < 0.001, and WMD: 9.35, 95% CI: 6.43-12.27, p < 0.001, respectively). These results suggested that theophylline has a beneficial effect on the prevention of acute kidney injury in neonates with perinatal asphyxia.

  • BACKGROUND/OBJECTIVES: The anti-obesity effect of quercetin-rich onion peel extract (OPE) was suggested in rats, but information from human studies is limited. This study aimed to investigate the effects of OPE on the body composition of overweight and obese subjects. MATERIALS/METHODS: In this 12-week, randomized, double-blind, placebo-controlled study, parallel clinical trials were performed in overweight and obese Korean subjects. Randomly assigned subjects were instructed to take daily either the placebo (male, 6 and female, 30) or OPE capsules containing 100 mg of quercetin (male, 5 and female, 31). Body composition was measured by using bioimpedance and dual-energy X-ray absorptiometry (DXA). Resting energy expenditure (REE) and respiratory quotient (RQ) were evaluated by using indirect calorie measurement methods. Fasting blood levels of glucose, insulin, lipids, and leptin were determined. RESULTS: Quercetin-rich OPE supplementation significantly reduced the weight and percentage of body fat as measured by DXA (P = 0.02). These effects were not shown in the control group. Levels of blood glucose (P = 0.04) and leptin (P = 0.001 for placebo, P = 0.002 for OPE) decreased in both groups. Significant increases in REE and RQ were observed in both groups (P = 0.003 for placebo, P = 0.006 for OPE) and in the OPE group alone (P = 0.02), respectively. CONCLUSIONS: Quercetin-rich OPE supplementation changed the body composition of the overweight and obese subjects. This result suggests a beneficial role of the anti-obesity effect of OPE human subjects.

  • Anti-inflammatory factor(AIF) is a water soluble extract of three herbs, Panax notoginseng(Burk.) F. H. Chen, Rehmannia glutinosa Libosch and Eleutherococcus senticosus. The present study aimed to investigate the safety and efficacy of herb extracts, AIF, on Korean knee osteoarthritis patients for six weeks. Fifty seven patients with knee osteoarthritis, ranging from 43 to 73 years of age, who fulfilled the "American College of Rheumatology"(ACR) classification of idiopathic osteoarthritis of knee and radiographic criteria were randomly selected and enrolled for the study. After initial screening and resting period, two capsules each of AIF(Each capsule contains; 400 mg) and similar identical placebo were administered twice a day to both groups. Pain intensity at second, fourth, and sixth weeks of study as well as one week after discontinuation of drugs was assessed by using 100 mm visual analogue scale(VAS). Changes in the Korean version of the Western Ontario and McMaster Universities(K-WOMAC) index score were compared at the initiation and completion of the study. VAS assessed by patients were significantly reduced(at visit 2; $54.64{\pm}14.72$, at visit 4, $37.32{\pm}16.58$, p<0.001) after AIF administration. Results showed an improvement in the physical function of K-WOMAC scale which was significantly higher(p=0.013) in AIF than placebo group, and decreases of total K-WOMAC score were also significantly higher(p=0.030) in AIF groups than placebo group. No serious adverse effect was observed, and there was no difference in incidence of adverse effect between AIF and placebo groups. In this population of Korean patients with knee osteoarthritis, AIF was found to be safe, tolerable and effective for symptomatic improvement of pain and physical function.

  • Background: Kinesiology taping (KT) is a method that helps immediately increase muscle activation, strength and joint stability by being attached to various skeletal muscles and structures of the body. Objectives: To investigate the effect of KT applied below the hyolaryngeal complex on the movement of the hyolaryngeal complex during swallowing in patients with dysphagia after stroke. Design: One-group, pre-post design. Methods: Twenty individuals with dysphagia after stroke participated in this study. KT was applied to the sternum and both clavicles from the hyolaryngeal complex. We analyzed the motion of the hyolaryngeal complex during swallowing with and placebo KT and KT using the Image-J software with videofluoroscopic swallowing study. In addition, a 0-to-10 numerical rating self-report scale was used to check the required effort and resistance felt during swallowing. Results: KT condition showed that the anterior and superior movement of the hyoid bone during swallowing was significantly lower than placebo KT (P<.05, all). Also, KT condition showed that the anterior and superior movement of the larynx during swallowing was significantly lower than placebo KT (P<.05, all). In result of statistical comparison between KT group and placebo KT group, the KT group showed significantly higher self-report scale score than the placebo KT group in terms of two category; the required effort and resistance felt (P<.05, all). Conclusion: This study demonstrated that KT applied below the hyolaryngeal complex inhibits the anterior and superior movement of hyoid bone and larynx during swallowing of patients with dysphagia after stroke.
