Objectives : The purpose of this study is to determine clinical efficacy of herbal medicine by evaluating SCORAD Index and total level of ceramaides in the skin of 13 children with atopic dermatitis Methods : Subjects are divided into two groups : Group 1(non-differentiation children treated with Saenghyeoryunbueom) and group 2(differentiation children treated with either pyungwisan, onchungum or gamitongsungsan). We determine SCORAD Index and total level of ceramaides in the skin of 13 children with atopic dermatitis before and after taking each of herbal treatment for 12 weeks. Results : After herbal prescription for 12 weeks, A SCORAD index of both group 1 and group 2 was decreased. However, the total level of ceramides in group 1 and group 2 was not altered after 12 weeks. When the correlation between the alteration of SCORAD index and ceramides levels was determined, the SCORAD index in group 1 was inversely correlated with the total level of ceramides(r=-0.994, p=0.006) In contrast, the alteration of SCORAD index in group 2 was not correlated with ceramide levels. Conclusions : The clinical efficacy of Saenghyeoryunbueom for non-differentiation children with atopic dermatitis is paralleled with the increased level of ceramides in skin. The clinical efficacy of pyungwisan, onchungum or gamitongsungsan for differentiation children with atopic dermatitis is not correlated with ceramide level in skin.

Yttrium (Y) and niobium (Nb) doped spherical $Li_4Ti_5O_{12}$ were synthesized to improve the energy density and electrochemical properties of anode material. The synthesized crystal was $Li_4Ti_5O_{12}$, the particle size was less than $1{\mu}m$ and the morphology was spherical and well dispersed. The Y and Nb optimal doping amounts were 1 mol% and 0.5 mol%, respectively. The initial capacity of the dopant discharge and charge capacity were respectively 149mAh/g and 143 mAh/g and were significantly improved compared to the undoped condition at 129 mAh/g. Also, the capacity retention of 0.2 C/5 C was 74% for each was improved to 94% and 89%. It was consequently found that Y and Nb doping into the $Li_4Ti_5O_{12}$ matrix reduces the polarization and resistance of the solid electrolyte interface (SEI) layer during the electrochemical reaction.

Objectives The purpose of this study was to examine the characteristics of diagnostic pattern questionnaire associated with Body Mass Index in premenopausal women. Methods We studied 41 patients visiting Gangdong Kyung Hee University Hospital from 1st April 2011 to 25th May 2011. The subjects were categorized in two groups, overweight & obesity group (n=12) and low weight & normal group (n=29). We studied the difference of diagnostic pattern questionnaire scores between two groups by Independent samples T-test and correlation between diagnostic pattern questionnaire scores of overweight & obesity group by Pearson's correlation coefficient test using SPSS for windows (version 13.0). Results Blood stasis, retention of undigested food, cold pattern scores of overweight & obesity group were non-significantly higher than low weight & normal group. Heat pattern score of overweight & obesity group was significantly higher than low weight & normal group. Cold-heat, phlegm-cold, blood stasis-cold, phlegm-blood stasis, phlegm-retention of undigested food significantly showed positive correlation coefficient in overweight & obesity group. Conclusions The results suggest that obese women tend to show heat pattern. It seems to be that multiple factors such as phlegm, blood stasis, retention of undigested food are causative of obesity.

Objectives : The aim of this study was to investigate the characteristics of Ryodoraku and association of Ryodoraku in Idiopathic Facial Paralysis Patients Methods : Subjects were 53 patients with Facial palsy patients and 28 normal people. We calculated the average Ryodoraku score(RS, ${\mu}A$) and each variation from physiologic range of 12 Ryodoraku points, and investigated the incidence when left and right points were simultaneously below(bilateral deficiency) or above(bilateral excess) physiologic range. Results : The electric current value of several meridian of normal group was more higher in idiopathic facial palsy group than in normal group. The measurement value of Ryodoraku followed sex was not significant statistically. Conclusions : These findings suggest that the measurement value of several Meridians of Ryodoraku is more higher in idiopathic facial palsy group than in normal group, because Ryodoraku has low correlation with Parasympathetic nerve.

Objectives : Recent well-designed randomized controlled trials(RCTs) and their meta-analysis have been published on the efficacy of acupuncture in different condition. In most of them, real acupuncture is compared with sham acupuncture including invasive and non-invasive sham methods. But it is not clear how active sham methods are. These results tend to lead the conclusion that acupuncture has no more effective than sham acupuncture. In order to investigate that sham acupuncture is appropriate as a control, we reviewed several acupuncture trials using different sham acupuncture as a control. Methods : We searched Cochrane researches of acupuncture, reviewed and analyzed 25 RCTs in 42 Cochrane reviews. And especially we compared the effect of acupuncture according to the type of sham acupuncture. Results : Invasive sham acupunctures are used in 12 RCTs and non-invasive types are used in the rest. The majority of studies(19 RCTs) fail to show effects beyond a sham acupuncture. Streitberger's sham needle is a validated sham acupuncture of non-invasive type that was used in 8 trials and also no significant group differences are shown except one trial. Conclusions : Acupuncture is a complex intervention. Clinical trials of acupuncture need to be reexamined and redesigned to remove several bias. Especially, sham acupuncture as a control might be investigated for physiological effects as well as validation test including patient-blinding and de qi sensation. Other research need to be investigated and developed for acupuncture trials.

This study was performed to evaluate hepatoprotective effect of Daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by $CCl_4$ and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase (LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid peroxidation, catalase and glutathione-S-transferase(GST) in liver microsome were determined in hepatotoxic rats induced by $CCl_4$ DWT DWT was significantly reduced the serum ALT, AST, ALP, LDH, TC and TG levels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of $CCl_4$-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5,000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks. DWT did not induce any toxic signs in the mortalities, clinical signs, body weight changes, and gross necropsy findings of mice. Based on these results, it is concluded that DWT may have the hepatoprotective effect on $CCl_4$ induced hepatotoxicity in rats. Also, DWT may have no side effect and its $LD_{50}$ value may be over 5,000 mg/kg b.w. in mice.
