  • The red algae Gracilaria vermiculophylla is widespread on seashores worldwide and has been used as food in Asian countries. Previous studies have reported that extracts of Gracilaria red algae have beneficial anti-oxidant and anti-inflammatory effects. The present study examined the anti-senescence effects of Gracilaria vermiculophylla extracts (GV-Ex) in replicatively senescent human bone marrow mesenchymal stem cells (hBM-MSCs). GV-Ex pretreatment improved the cellular viability of hBM-MSCs that had been injured by oxidative stress. These effects of GV-Ex were confirmed by MTT assay and immunoblot analysis using the apoptotic proteins p53 and cleaved caspase-3. The reactive oxygen species (ROS) levels were examined in long-term cultured Passages 17 (P-17) mesenchymal stem cells (MSC) and compared to P-7 MSC. The ROS accumulation was greater in the P-17 than in the P-7. However, these increased ROS levels in the P-17 were decreased significantly after treatment with GV-Ex, and restoration of the levels of the anti-oxidant enzymes SOD1, SOD2, and CAT was also observed under these conditions. In addition, P-17 hBM-MSC treated with GV-Ex had decreased levels of the senescence proteins p53, p21, and p16. The results show that the ability of P-17 hBM-MSC to differentiate into osteocytes and adipocytes was improved by GV-Ex treatment, suggesting that GV-Ex ameliorates the functional decline of senescent stem cells.

  • This study was carried out to acquire some basic biological informations on the granulosis virus (GV) of Pieris rapae and Pieris brassicae. Purified fractions of GV capsules in an sucrose density gradient centrifugation yielded on homogenous and sharp peak without a shoulder. Electron microscopy revealed that GV capsules were mostly ovalglove in shape. P. rapae and P. rapae GV isolated from P. rapae comprised granules($396\pm38\times238\pm25nm$ for P. rapae GV. $375\pm40\times255\pm28nm$ for P. brassicae GV) which contained single virus particle. The virus particles were 250- $275{\times}63$ -73nm for P. rapae GV and 243-250 $\times$ 63-75nm for P. brassicae GV containing a nucleocapsid 225 $\times$ 31nm for P. rapae, 225 $\times$ 29nm for P. brassicae within an envelope. The virulent difference between the two viruses was very small in their virulence for P. rapae larvae showing the $LC_{50}$( -log) with 5.5673 for P. rapae GV and 5.8104 for P. brassicae GV. Also the $LT_{50}$ of the 3rd instar P. rapae larvae against $10^{-6}$ inoculum was 8.17 days for P. rapae GV and 7.16 days for P. brassicae GV.

  • Purpose : This study was performed to compare the characteristics of digital infrared thermographic imaging(DITI) in polycystic ovary syndrome(PCOS) patients with regulary cycling controls. Methods : We studied 19 patients visiting ${\bigcirc}{\bigcirc}$ korean hospital from 7th May 2010 to 8th January 2011. The subjects were categorized in two groups. 8 PCOS patients and 11 healthy regularly cycling controls. We investigated the difference of DITI between two groups by Mann-Whitney U-test using SPSS for window (version 17.0). Results : The average temperatures of five points(In-dang(EX-HN3), GV4, GV6, GV12, GV17) between PCOS and non-PCOS groups showed a little difference though p-value is not less than 0.05. The DITI differences of PCOS group between In-dang and thorax or between In-dang and abdomen showed lower than those of non-PCOS group though not a statistical significant level. Conculsion : The results suggest that DITI differences between PCOS and non-PC OS groups need to be developed to some degree for the diagnosis tool of PCOS.

  • Objectives : This research aimed to verify the validities of contraindicated acupoints in acupuncture treatment in Zhenjiudacheng. Methods : We investigated contraindicated acupoints when performing needling in Zhenjiudacheng, then verified them in today's medical knowledge and clinical studies. Results : In Zhenjiudacheng, 39 acupoints - LU2, LI4, LI13, LI14, LI16, ST1, ST9, ST12, ST17, ST25, ST30, ST42, SP6, SP11, SI18, BL8, BL9, BL56, KI11, TE7, TE8, TE19, TE20, GB3, GB18, GB21, GV10, GV11, GV17, GV22, GV24, CV1, CV4, CV5, CV8, CV9, CV15, CV17 and EX-HN11 - were described to need a careful approach in acupuncture treatment and 21 acupoints among them had contraindications. Most of the contraindications can be explained based on anatomical knowledge and results of clinical studies, and acupuncture treatment at the 39 contraindicated acupoints can induce injury of tissues or organs near the acupoints. Conclusions : The contraindicated acupoints in acupuncture treatment in Zhenjiudacheng seem to have been classified based on the adverse events experienced by doctors at that time. Therefore careful acupuncture treatment at these acupoints is needed to avoid injury to tissue or organs.

  • Objectives: Yamen is the fifteenth acupoint of the Governor Vessel Meridian (GV15). It is anatomically close to the medulla oblongata, so finding the safety depth of the acupoint is very important. However, few studies on the safety depth of GV15 have been done. Methods: This study tried to measure the safety depth of GV15 by using magnetic resonance imaging (MRI) scans and to analyze the factors affecting the safety depth through multiple regression analyses. This study was carried out for patients who had a brain MRI scan while visiting Jeonju Wonkwang Hospital, Korea. The shortest distance between the glabella and the occipital protuberance (DGO), the horizontal distance between the glabella and the back of the head (DGB) and the dangerous depth (DD) were measured from the sagittal views of the MRI images. The DD is the horizontal distance from the skin's surface at GV15 to the spinal dura mater. Results: The model suggested that the safety depth (SD) was significantly associated with gender (${\beta}$ = 0.474, P < 0.0001), DGO (${\beta}$ = 0.272, P = 0.027), and BMI (${\beta}$ = 0.249, P = 0.005) and the combination of three variables can explain the SD, with $R^2$ = 0.571 (Table 3). A longer SD was associated with males and with greater BMI and DGO. Conclusion: This study suggests that gender, BMI and DGO may be important factors when the SD of GV15 is considered clinically through a multiple regression analysis of GV15.

  • Objectives : The authors aimed at contributing to the safety of acupuncture in the clinic by analyzing the information of contraindicated acupoints described in Uihakipmun. Methods : We investigated the contents related acupuncture contraindications in Uihakipmun, categorized the contraindicated acupoints by site and identified whether they can cause adverse events from the anatomical point of view. Results : In Uihakipmun, 49 acupoints - BL6, BL8, BL9, ST1, SI18, BL1, BL2, TE18, TE19, TE20, GB1, GB3, GV22, GV24, ST12, ST9, TE16, GV6, BL15, BL30, CV17, LU2, GB22, SP16, CV8, CV9, CV15, KI11, ST30, SP11, BL56, GB32, GB33, GB42, LI13, HT2, TE8, GV17, GB18, EX-HN11, GB21, GV11, GV10, ST17, CV5, CV1, ST42, SP6, LI4 - were described as contraindicated acupoints. Among them, the contraindications induced by acupuncture treatment were described for just 5 acupoints. Anatomically, acupuncture stimulation at the contraindicated acupoints can cause organ, nerve or vessel damage near the acupoints. And the number of contraindicated acupoints in Uihakipmun was increased compared to those in Hwangjenaegyeong, Chimgugabeulgyeong, Bigeupcheongeumyobang, Donginsuhyeolchimgudogyeong and Chimgujasaenggyeong. Conclusions : In Ming dynasty, the knowledge associated with adverse events on acupuncture was increased by the accumulation of medical knowledge. Acupuncture stimulation at the contraindicated acupoints described in Uihakipmun can cause tissue damage, therefore we should perform acupuncture procedure carefully to avoid adverse events when stimulating the contraindicated acupoints.

  • Background: For standardizing of Han-Yeol [寒熱], which is a kind of diagnosis method in oriental medicine, it is necessary to investigate into relationship of symptoms and signs representative of Han-Yeol [寒熱] to the biofunctional medical signals; thermal temperature by Thermography, Pulse-Respiration Ratio and so on. By correlation analysis of these data items acquired from patients, it could be provides the fundamental data for standardizing of Han-Yeol [寒熱]. Objectives: We performed this study to check the characteristics of thermal temperature with Han-Yeol [寒熱] statue by pulse-respiration ratio. Methods: We selected nine regions around acupoints including Yin dang[印堂], Sugu[水溝, GV26], Ch'ondol[天突, CV22], Chonjung[CV17], Chung-wan[中脘, CV12], Chonchu[天樞 S25], No-gung[勞官, P8], and calculated based on the utility of R.O.I.(Region of Integer) by IR-2000 these points temperature from 68 subjects. In practicing pulse-respiration ratio over 4.0 means the statues of Yeol [熱], pulse-respiration ratio below 4.0 means the statues of Han [寒]. To optimum conditions thermal temperature, which are not effected by internal and external variables, we studied preceding research. The results shows that optimal time period is 20minutes after undressed and the optimal region is the region around acupoints including Sugu [水溝, GV26]. Based on a preceding research results, we analyzed these data by Paired T-test between GV26 Region and 8-Thermography Regions and two-way repeated ANOVA with thermography$({\Delta}T)$ and Han-Yeol [寒熱] statue by pulse-respiration ratio. Results: 1. In applying of two-way repeated ANOVA with thermography$({\Delta}T)$ and Han-Yeol [寒熱] statue by pulse-respiration ratio, Sugu [水溝穴, GV26] - [印堂穴, HN1], Sugu 水溝, GV26] - Chonjung[CV17], Sugu [水溝, GV26] -Chung-wan[中脘, CV12]had significant differences. 2. In applying of Paired T-test between Sugu [水溝穴, GV26] Region and 8- Thermography Regions, there were significant differences except of Sugu [水溝穴, GV26] -Chondolp[天突, CV22]. 3. In the difference of Sugu [水溝, GV26] -Chung-wan[中脘, CV12], thermal temperature increases a lot in the statues of Yeol [熱], thermal temperature decreases a lot in the statues of Han [寒]. Conclusions: On the analysis of Thermography, we obtain the measurement conditions were considered the individual variations. And it is different that the thermal temperature change on Thermography according to Han-Yeol [寒熱] statue by pulse-respiration ratio.
