Shangwan(CV13), Zhongwan(CV12), Xiawan(CV10), Hefu(L14) and Taichong(LR3) which belong to Conception Vessel and stomach meridian are acupuncture points frequently used for healing gastrointestinal desease in oriental medicine. The present study was conducted to see the effects produced by combined acupuncture(A), electro-acupuncture(EA) and moxibustion using five acupoints which belongs to different meridians on serum gastrin level in rats. Electro-acupuncture (2 Hz, intensity; 10 times muscle twitch threshold) was applied for 30 minutes to Hefu(LI4), Taichong(LR3) under halothane anesthesia. Moxibustion ($1.6{\pm}0.3\;mg$, 5 times of a day) was applied during 3 days to CV10, CV12, CV13 under halothane anesthesia. Combined stimuli of acupuncture at Hefu(LI4), Taichong(LR3) and moxibustion at CV13, CV12 increased serum gastrin level significantly eventough combined simulus of moxibustion on CV 10 was not shown any change. And combined stimul of EA and moxibustion at experimental all groups were not shown any effects. These data suggest that effects of acupuncture and moxibustion are depentent with used acupoints and combination stimuli method.

Objectives : This study aimed to investigate the difference of abdominal skin temperature responses following moxibustion comparing stimulation method. Methods : Moxibustion was applied on the acupuncture points of $CV_4$, $CV_6$, $CV_{12}$. Thirty healthy men were randomly divided into two groups, one receiving a single moxibustion stimulation in three locations '$CV_4{\cdot}CV_6{\cdot}CV_{12}$'(n=15) and the other receiving triple moxibustion stimulations in one location '$CV_{12}$'(n=15) for 30 min. To obtain the skin temperature on abdominal region, a thermograph was used. Three arbitrary frames(the upper abdominal, lower abdominal, whole abdominal regions) were made to analyse skin temperature. Thermographic images were obtained at before and after the procedure of indirect moxibustion and 5, 10, 15, 20, 25, 30 min afterwards. Results : An increase in skin temperature on the three abdominal regions was observed following both one point and three points moxibustion administrations. Significant increase in skin temperature of the whole abdominal region was observed at 30 min after the procedure of three points moxibustion compared with one point moxibustion stimulation. A tendency of skin temperature changes over time was observed. Conclusions : In this study, skin temperature of lower abdominal region does not increase after triple moxibustion stimulations on $CV_{12}$. Administration of single moxibustion on $CV_4$, $CV_6$, $CV_{12}$ makes greater changes in skin temperature on the whole abdominal region than triple moxibustion on $CV_{12}$.

Four foreign pasture cultivars such as Lotus corniculatus cv. Maitland, Trifolium pratense cv. Deben, Lolium perenne cv. $S_{23}$ and .Dactylis glomerata cv. $S_{26}$ were tested with "Kwisan" series, a common upland soil in Southern part of Korea. The cultivars in single or mixture were grown in pot with two levels of light intensity, i.e. a full sun light condition and 50% interception. Dry matter yield of top and root and their seasonal changes, the number of tillers or branches per plant and finally competative effects of mixtures were evaluated by estimating the expected yield, relative yield totals and compensation index. The results are summarized as follows: 1. Maitland showed a significant decrease in dry matter yield in shade condition, but the number of branches of Maitland was higher than those of Deben. 2. Maitland showed higher dry matter yield than Deben during the mid-summer period, while $S_{23}$, showed higher dry matter yield than $S_{26}$ during early season. 3. Mixtures of $S_{23}$ and Maitland, and $S_{26}$ and Deben gave better response to grasses by increasing the number of tillers in shade condition. 4. Combinations of Lotus corniculatus cv. Maitland and Dactylis glomerata cv. $S_{26}$ and Trifolium pratense cv. Deben and Dactylis glomerata cv. $S_{26}$ gave higher relative yield totals and higher compensation index, which envisages that the pasture establishment rates can be enhanced when those mixtures were sown by the oversowing method in the upland soil where phosphate level is very low and infertile in general.n general.

Purpose: We intended to research the relations between abdominal temperature and primary dysmenorrhea severity. Methods: We selected the 95 primary dysmenorrhea patients by means of screening test (first screening test-inquiry, second screening test-clinical test, additionally Waist-to-Hip ratio (WHR) by Inbody 2.0). We measured 4 points abdominal temperature (Chon-jung(CV17), Chung-wan(CV12), Kwan-won(CV4), Chung-guk(CV3)) by DITI (DOREX Inc., USA). And then we checked the difference of temperature $({\Delta}T)$ between CV17 and CV4 / CV17 and CV3 / CV12 and CV4 / CV12 and CV3. After that, we compared ${\Delta}T$ with primary dysmenorrhea severity evaluated by multidimensional scales (verbal rating scale modified from the one devised by Bibe roglu & Berhrman(VRS; B&B), multidimensional verbal rating scale by Andersch & Milsom(MVRS)). In dysmenorrhea severity, we standardized scale score and 3-group-severity by score (mild, moderate, severe). For statistics, we used Pearson correlations and Spearman's rho correlations, SPSS 11.0 for windows. Results: In case of MVRS, MVRS score and 3-group-severity were not correlated to ${\Delta}T$. In case of VRS; B&B, VRS; B&B score was correlated to ${\Delta}T$ (CV12 and CV4 / CV12 and CV3) and 3-group-severity was correlated to ${\Delta}T$ (CV12 and CV3). Statistically they showed significant result (p<0.05). So we can consider that ${\Delta}T$ (CV12 and CV3) and the primary dysmenorrhea severity by VRS; B&B are most correlated. Conclusion: The primary dysmenorrhea patients showed that severity by VRS; B&B was connected with ${\Delta}T$ (CV12 and CV3). So we can consider DITI as primary dysmenorrhea evaluation instrument and must further research measurement points for the exact primary dysmenorrhea evaluation by DITI.

Purpose: Although premsnstrual syndromes(PMS) have long been recognized, there has been difficulty to evaluate the symtoms. Usually the questionnaire has been used to dignose the PMS. Objective is to investigate the relationship of body temperature between women with PMS and without PMS. Methods: We studied 23 patients visiting OO hospital from 26th December 2005 to 26th April 2006. The Questionnaire for PMS was used to evaluate physical, emotional, and behavioral symptoms accompanying the menstrual cycle of the subjects. The subjects were categorized in two groups, non-PMS(11) and PMS group(12). Body temperature was assessed by Dorex spectrum 9000MB (DOREX Inc., USA). We measured CV4, CV3, CV12 and CV17 to evaluate the distribution of body temperature, compared the difference of temperature(${\Delta}T$) between CV17-CV4, CV17-CV3, CV17-CV12 and CV12-CV3. We investigated the of temperature and ${\Delta}T$ between two groups by Mann-Whitney U-test. Results: The temperature of CV3 and CV4 of PMS located in low abdomen were lower than those of non-PMS located in chest. But there was no statistical significance of temperature between two groups. There was lower temperature of low abdomen in PMS group than non-PMS group without statistical significance. Conclusion: The results suggest that DITI could be useful to assess the PMS objectively. But more research should be needed.

Cyclic voltammetry and chronocoulometry have been used for characterization of catechol violet (CV) at the hanging mercury drop electrode in acetic acid-sodium acetate buffer solution. At pH 2.94 a nearly symmetric cyclic voltammetric wave due to an irreversible weak adsorption of CV on mercury was obtained at concentration of $0.53{\mu}mol\;dm ^{-3}$. Under these conditions, CV adsorbes in a monolayer. Upon increasing the concentration, the symmetry of the wave decreases; it can be attributed to a mixed diffusion adsorption process. The amount of the adsorbed catechol violet on the HMDE expressed as surface concentration as well as the surface areaf occupied by one molecule$(\sigma)$ were calculated. It was found that the values obtained for f and o utilizing cyclic voltammetric and chrono-coulometry are almost identical. A 1:1 and 1:2 Th (IV)-CV complexes are formed on addition of thorium (IV) to catechol violet. These complexes are adsorbed and reduced on the HMDE at more negative potentials than the peak potential of free CV, Using the square-wave (SW) technique, the adsorptive cathodic stripping voltammetry, ACSV, of these complexes was studied. It was found that the SW-ACSV of Th(IV)-CV can be applied to the determination of thorium at the nanomole level. Optimum conditions and the analytical method of determination were presented and discussed.

Tomato (Solanum lycopersicum) is one of the most widely grown and economically important vegetable crops in the world. Tomato chlorosis virus (ToCV) is one of the recently emerged viruses of tomato distributed worldwide. ToCV-tomato interaction was investigated at the molecular level for determining changes in the expression of tomato genes in response to ToCV infection in this study. A cDNA library enriched with genes induced in response to ToCV infection were constructed and 240 cDNAs were sequenced from this library. The macroarray analysis of 108 cDNAs revealed that the expression of 92 non-redundant tomato genes was induced by 1.5-fold or greater in response to ToCV infection. The majority of ToCV-induced genes identified in this study were associated with a variety of cellular functions including transcription, defense and defense signaling, metabolism, energy, transport facilitation, protein synthesis and fate and cellular biogenesis. Twenty ToCV-induced genes from different functional groups were selected and induction of 19 of these genes in response to ToCV infection was validated by RT-qPCR assay. Finally, the expression of 6 selected genes was analyzed in different stages of ToCV infection from 0 to 45 dpi. While the expression of three of these genes was only induced by ToCV infection, others were induced both by ToCV infection and wounding. The result showed that ToCV induced the basic defense response and activated the defense signaling in tomato plants at different stages of the infection. Functions of these defense related genes and their potential roles in disease development and resistance to ToCV are also discussed.
