Objectives This study is conducted to evaluate Th2 skewed condition control through skin fat barrier formation from the treatment using Coptidis Rhizoma and Glycyrrhiza uralensis extract. Methods The 6-week-old NC/Nga mice were divided into 4 groups: Control group (Ctrl), lipid barrier eliminate treatment group (LBET), Coptidis Rhizoma and Glycyrrhiza uralensis feeding treatment after lipid barrier elimination group (CGFT), dexamethasone feeding treatment after lipid barrier elimination group (DxFT). After 3 days, differences in skin condition, improvement of skin fat barrier, and control of Th2 skewed condition of each group were observed. Results Pathologic skin damage and tissue changes were less in the CGFT group than in the LBET and DxFT groups, and Transepidermal water loss (TEWL) and pH were also significantly decreased (p < 0.05). The filaggrin intensity and positive response also increased significantly in the CGFT group (p < 0.05). Kallikrein-related peptidase (KLK) 7, Protease activated receptor (PAR)-2, Thymic stromal lymphopoietin (TSLP), Interleukin (IL)-4, and the products of the Th2 differentiation process also showed a significant decrease compared to the LBET and DxFT groups (all p < 0.05). Conclusions The Coptidis Rhizoma and Glycyrrhiza uralensis extract causes skin barrier recovery and function recovery through the formation of skin fat barrier. This leads to the conclusion that Coptidis Rhizoma and Glycyrrhiza uralensis extract can control Th2 differentiation through the formation of skin fat barrier.

As an effort to select powerful anti-cariogenic materials from natural resources, various plant extracts were examined for their anti-S. mutans and anti-glucosyltransferase (GTase) activities. The ethanol extracts of licorice bark, which was produced after water extraction of licorice, showed the most powerful anti-S. mutans as well as anti-GTase activities. When licorice bark was consecutively fractionated with n-hexane, chloroform, ethylacetate, and butanol, the chloroform fraction exhibited the strongest anti-S. mutans activites. This fraction was further fractionated into 4 fractions through a silica gel column, and according to HPLC analysis, anti-S. mutant activities seemed to come mostly from relatively hydrophobic materials.

The purpose of this case-series study is to report the effect of Seungmahwangryeontang-gami and facial venesection on Hot flush patients. For this report, two of patients had taken Seungmahwangryeontang-gami for 45 days and the other patient had taken eungmahwangryeontang-gami for 60 days. Also, one of the patients had taken twice facial venesection, and the other two patients had done it three times during the treatment. During this period, we tried to find out that there were objective change and subjective change in reduction of hot flush. We were going to ascertain the subjective change through the change of VAS score. In case of objective change, we used the change of the color which were taken by the Derma Vision. The result of the treatment, each patients' VAS score reduced from 73 to 41, 67 to 44, and 71 to 51. Based on the Derma vision's facial color change, the score of Red and Dark Red, which mean Hot flush, were reduced. On the other hand, that of Blue and Dark Blue were increased. According to the results, we had obtained positive clinic effects from Seungmahwangryeontang-gami and facial venesection on Hot flush patients respectively. Although this report is based on few patients' treatments on hot flush with Seungmahwangryeontang-gami and facial venesection, we can use this result in a good way. However, the limitation of this report is that we can't generalize the following result because of the lack of the cases and we can't present a conclusive evidence which can prove the validity of the Hot flush from the case-series study.

The present study was undertaken to estimate the antibacterial effect of a combination of C. rhizoma, L. Flos, and P japonica (1:1:1) extracts (CLP1000) and a combination of the herbal extract mixture and dioctahedral smectite (CLPS1000) against murine salmonellosis. At the concentration of CLP1000 and CLPS1000 0.5 mg/ml, the antibacterial effect was not showed on Salmonella typhimurium (S. typhimurium). On the other hand, the antibacterial effect against S. typhimurium was observed at the concentration of CLP1000 and CLPS1000 1.0 mg/ml. Oral administration of Smectite, CLPl000, and CLPS1000 at the dose of 10 mg/ml showed a therapeutic effect for S. typhimurium infected BALB/c mice. The mortality of Smectite, CLP1000 and CLPS1000-treated mice was 90%, 90%, and 70% at 12 days, respectively, while that of untreated mice was 100% at 9 days after a lethal dose of S. typhimurium infection. The results of our study strongly indicate that CLPS1000 has potential as an effective of salmonellosis.

We previously reported the protein isolated from Coptidis Rhizoma (CRP), which has antifungal activity against a fungal pathogen, Candida albicans. In the current study, we investigated what portion in the CRP is responsible for the antifungal activity. For the investigation, the CRP was fractionated on a Shepadex G-50 column. Data resulting from the fractionation, seven fractions were obtained. Fractions (Fr.) I, II, and III eluted initially from the column showed no inhibitory effect on the growth of C. albicans, whereas Fr. IV, V, and VI eluted later revealed inhibition of the growth, and Fr. IV and VI showed potent antifungal activity by broth susceptibility analysis. However, Fr. VI was contained in the CRP more than Fr. IV, which led us to select the VI for the following experiments. In a murine model of a subcutaneous candidiasis caused by C. albicans, the Fr. VI displayed a therapeutic effect on nude mice pretreated with anti-neutrophil monoclonal antibody (RB68C5) and then infected subcutaneously with live C. albicans. At day 16, these mice were healed almost up to 78% of the infected area when compared to infected area of control nude mice that received diluent (Dulbecco's Phosphate-Buffered Saline; DPBS), instead of the Fr. VI (P<0.01). The Fr. VI blocked hyphal formation from blastoconidial form of C. albicans (P<0.01), which might prevent penetration of hyphae to the deeper site of skin and thus helps the healing. In the ionic strength test, the effect of Fr. was influenced by $Ca^{2+}$ ion just like other known antimicrobial peptides, but the influence was affected at an extremely high concentration such as 500 mM. Thus, such ion-concentration is considered to be meaningless in the clinical situation. Considering all data together, Coptidis Rhizoma is appeared to produce an antimicrobial peptide that has therapeutic effect on subcutaneous infection caused by C. albicans.

Growth characteristics and crude protein content of soybean sprouts cultivated with extracts of some Korean herb medicines for 4 days were investigated. Extracts of Korean herb medicines were utilized and adjusted to 100 ppm, 200 ppm, 300 ppm and 400 ppm as culturing water of soybean sprouts. Of Korean herb medicines tested, extract of Panax ginseng was most effective to increase of weight and length of soybean sprouts, followed by Glycyrrhiza glabra. Extracts of Angelica gigas and Cnidium officinale were similar with that of control group. Extract of Coptidis japonica inhibited the growth of soybean sprout. Optimal concentrations of extracts of Glycyrrhiza glabra and Panax ginseng for growth of soybean sprout were 100 ppm and 200 ppm, respectively. Weight of soybean sprout cultivated with extract of Panax ginseng (PGE) was increased to 7.2%(wet basis) as compared with that of control group. Length of soybean sprouts cultivated with 200 ppm of PGE was accelerated to 32% and increased to 50% in soybean sprout cultivated for 3 days. Crude protein contents of soybean sprout cultivated with extract of Angelica gigas or Panax ginseng was slightly increased according to cultivation period. In Cnidium officinale group, crude protein contents was increased at a 300∼400 ppm concentration and 4 days of cultivation.

Objective : In this study, we investigated the effects of Hwangryunhaedoktang Herbal-acupuncture(HHT) at a acupoint, $G_{21}$(Kyonjong) on the Heart Rate Variability(HRV) in adults, as well as we tried to observe how HHT affects on the balance of the autonomic nervous system. Methods : The subject were comprised of 20 healthy adults, who didn't take any drugs which affected on the autonomic nervous system and had normal sinus rhythm in electrocardiogram. The control group was comprised of 9 subjects, who were injected normal saline at $G_{21}$(Kyonjong). The experiment group consisted of 10 subjects, who were injected HHT at $G_{21}$(Kyonjong). We measured HRV by CANS 3000 on three times : before, immediately after, and 20 minutes after injection. The SPSS 10.0 for windows was used to analyze the date and the Wilcoxon signed rank test (in group) and Mann-Whitney U-test(between two groups) were used to verify the results. Results : The following results were obtained ; 1. In each group, Mean-HRV and Mean-RR showed a significant change during 20 minutes after injection. But there were no significant difference between two groups(p>0.05). 2. In experiment group, 20 minutes after injection, norm LF and LHR showed a significant decrease and norm HF showed a significant increase. There were significant difference between two groups(p<0.05). Conclusions : The findings suggest that HHT at $G_{21}$(Kyonjong) in adults relatively activate parasympathetic nervous system and inactivate sympathetic nervous system.
