Objectives : This study was performed to find the desirable remaining time of needle in the acupuncture treatment. Methods : The 21 volunteers were given acupuncture at LU9 vertically and needles were remained for 2 min, 10 min, 15 min, 30 min, respectively. The thermographic change induced by acupuncture was measured with Digital Infrared Thermographic Image at the following acupoints: LU11, LU10, LU9, LU8, LU5, LU1, and PC7. The statistical significance of thermographic change was evaluated using paired t-test and post hoc Wilcoxon test. Results : The most significant changes after acupuncture were produced when needles were remained for 10 min or 15 min. LU11, LU5, LU1, and PC7 were the point at which all of the remaining time produced significant change commonly. At LU11, the biggest change was produced when needle was remained for 15 min, while at LU5, LU1, and PC7, the biggest change was produced when needle was remained for 30 min, and the smallest change was produced when needle was remained for 10 min at all of acupoints of LU11, LU5, LU1, and PC7. The unbalance between left side and right was decreased the most largely in 15 min group. Conclusions : The results of this study suggest that the desirable remaining time of acupuncture needle might be 15 min.

Purpose : This study was performed not only to compare the brain activation regions associated with sexual arousal induced by visual stimulation and SP6 acupuncture, but also to evaluate its differential neuro-anatomical mechanism in healthy women using functional magnetic resonance imaging (fMRI) at 3 Tesla (T). Subjects and methods : A total of 21 healthy right-handed female volunteers (mean age 22 years, range 19 to 32) underwent fMRI on a 3T MR scanner. The stimulation paradigm for sexual arousal consisted of two alternating periods of rest and activation. It began with a 1-minute rest period, 3 minutes of stimulation with either of an erotic video film or SP6 acupuncture, followed by 1-minute rest. In addition, a comparative study on the brain activation patterns between an acupoint and a shampoint nearby GB37 was performed. The fMRI data were obtained from 20 slices parallel to the AC-PC line on an axial plane, giving a total of 2,000 images. The mean activation maps were constructed and analyzed by using the statistical parametric mapping (SPM99) software. Results : As comparison with the shampoint, the acupoint showed 5 times and 2 times higher activities in the neocortex and limbic system, respectively. Note that brain activation in response to stimulation with the shampoint was not observed in the regions including the HTHL in the diencephalon, GLO and AMYG in the basal ganglia, and SMG in the parietal lobe. In the comparative study of visual stimulation vs. SP6 acupuncture, the mean activation ratio of stimulus was not significantly different to each other in both the neocortex and the limbic system (p < 0.05). The mean activities induced by both stimuli were not significantly different in the neocortex, whereas the acupunctural stimulation showed higher activity in the limbic system (p < 0.05). Conclusions : This study compared the differential brain activation patterns and the neural mechanisms for sexual arousal, which were induced by visual stimulation and SP6 acupuncture by using 3T fMRI. These findings will be useful to understand the theory of traditional acupuncture and acupoint channel in scientific point of view.

The aim of this study was to described the genetic structure of Eleutherococcus senticosus in Korea. We investigated 10 patches, which are eight Korean patches and two foreign patches come from Russia and China growing at Korean habitat, using ISSR(inter-simple sequence repeats) markers. In ISSR PCR, the overall percentage of polymorphic ISSR amplicons was 76% and the mean number of amplicons per ISSR primer was 11.5, which were higher than the RAPD results for the some cultivars collected in Korea(Kim et al., 1998) ; 57% and 5.7, respectively. So ISSR markers provide more powerful tool than RAPD markers for the investigation of genetic variation in E. senticosus. There are relatively high genetic variation among patches as 62.8%, but low variation within eight Korean patches. Such pattern of genetic variation, which is not ordinary in other tree species, may be result from the narrow and limited habitats and the asexual reproduction of this species at the natural stands in Korea. Although the small sample size in this study seemed to be resulted in the high genetic variation among patches, the overall genetic interpretation of this study might not be much affected on the basis of the characteristics of the distribution and the reproduction system of E. senticosus. Analysis of genetic distance between all pairs of the patches did not reveal any trends with regard to geographic distance, which was confirmed by the results obtained from AMOVA(analysis of molecular variance) and PCA(principal component analysis). These results suggest that, in addition to the preservation of the natural stands, the conservation of larger number of patches with small number of individuals per patch is more effective for the ex situ conservation and for maintaining the genetic diversity of E. senticosus in Korea than smaller patches with large number of individuals.

Objectives : Skin color deformation by cupping has been widely used as a diagnostic parameter in Traditional Korean Medicine(TKM). Skin color deformation such as ecchymoses and purpura is induced by local vacuum in a suction cup. Since existing studies have relied on a visual diagnostic method, there is a need to use the quantitative measurement method. Methods : We conducted an analysis of cross-polarization photographic images to assess the changes in skin color deformation. The skin color variation was analyzed using $L^*a^*b^*$ space and the skin erythema index(E.I.). The meridian theory in TKM indicates that the condition of primary internal organs is closely related to the skin color deformation at special acupoints. Before conducting these studies, it is necessary to evaluate whether or not skin color deformation is influenced by muscle condition. Hence, we applied cupping at BL13, BL15, BL18, BL20 and BL23 at Bladder Meridian(BL) and measured blood lactate at every acupoint. Results : We confirmed the high system measurement accuracy, and observed the diverse skin color deformations. Moreover, we confirmed that the $L^*$, $a^*$ and E.I. had not changed after 40 minutes(p>0.05). The distribution of blood lactate levels at each part was observed differently. Blood lactate level and skin color deformation at each part was independent of each other. Conclusions : The negative pressure produced by the suction cup induces a reduction in the volumetric fraction of melanosomes and subsequent reduction in epidermal thickness. The relationship between variations of tissue and skin properties and skin color deformation degree must be investigated prior to considering the relationship between internal organ dysfunction and skin color deformation.

This study was carried out to evaluate the quality characteristics of the vacuum packed pre-aged venison with seasoning during chilled storage. The ham of deer were cut to cube and two seasonings such as red pepper sauce (T1) or soy sauce (T2) were seasoned by the proportions or meat to seasonings (1:1), respectively. The seasoned venison was aging by fill into plastic box at $0\pm1^{\circ}C$ for 10 days. And then, the aged meat from each pack was vacuum-packaged and stored at $0\pm1^{\circ}C$ for up to 28 days. pH were significantly decreased with storage periods in all treatments (p<0.05). Salinity $(\%)$ were no significant differences in T1 during the whole storage, but T2 had significantly high content $(1.33\%)$ at the storage days of 28 (p<0.05). Saccarinity $(\%)$ of T1 were significantly higher than that of T2 during the whole storage periods (p<0.05). As storage time extended the value of $L^*$ and $b^*$ in T1 were increased and those values decreased in T2. $a^*$ and shear force $(g/cm^2)$ or T1 and T2 were increased as the storage period passed In the result of sensory evaluation. all treatment had relatively high score $(T1\;6.75\~T2\;7.00)$ in overall acceptability during the storage period of 28 days. In conclusion, this study suggest that vacuum packed pre-aged venison with seasoning may be useful for new deer meat menu.

Young radishes (YR, yeolmu in Korean) were cultivated in the soil with and without sulfur. YR-Control (without sulfur) was grown in the normal soil. YR were grown in the soil with $1,818\;g/m^3$ sulfur (YR-A) and $1,818\;g/m^3$ sulfur added lime mortar (YR-B) on it, respectively. Also, we prepared YR kimchis using YR-Control, YR-A and YR-B. The kimchis were fermented at $5^{\circ}C$ for 8 weeks. The growth inhibitory effects of AGS human gastric adenocarcinoma cells of the YR samples and kimchis were investigated. YR kimchis after $4\~5$ weeks at $5^{\circ}C$ showed higher acidity of $0.88\~1.20\%$ with pH $4.3\~4.5$ and the YR kimchis kept approximately pH 4.0 until 8 weeks. The kimchi A and B using YR-A and YR-B showed faster fermentation time, higher level of Leuconostoc sp. and lower level of Lactobacillus sp. during the fermentation, comparing to the control kimchi using YR-Control. Juices from YR-A and YR-B showed higher growth inhibitory effects of AGS human gastric adenocarcinoma cells than the juice from YR-Control at the same concentration. The growth inhibitory effect of YR-A was similar to that of the YR-B. The kimchi A and B juices also exhibited higher inhibitory effects $(74\%)$ on the growth of AGS human gastric adenocarcinoma cells than that of the control kimchi $(57\%)$ at the higher concentration of $20{\mu}L/assay$. Methanol extracts from the YR-kimchis also led to the similar results to the results of the juices. These results suggested that preparing of kimchi using differently cultivated YR especially in the soil with sulfur, which can help to synthesize sulfur-containing compounds, could increase the growth inhibitory effects of AGS human gastric adenocarcinoma cells.

Fifty four Hanwoo steers in final fattening period were assigned to 3 groups control, top dressed $PROSOL^{(R)}$ as an emulsifier (TP) and DSP group (experimental diet made to down spec of nutrients with $PROSOL^{(R)}$, which is sodium stearoyl-2-lactylate), based on the body weight (647.96${\pm}$41.31 kg) and months of age (27.3${\pm}$0.8 mo), and the experiment was conducted to establish the reasonable fattening method of Hanwoo steers for 91 days. Average daily body gains during trial were 0.94, 0.84 and 0.98 kg in control, TP and DSP, respectively (P=0.011). DDMI/ADG of TP group tend to lightly improving compared to control and DSP group (P=0.692). There was no effect of supplementation of the $PROSOL^{(R)}$ in concentrates on growth rate, feed efficiency and shrinkage in Hanwoo steers during the short final fattening period. MQI from TP and DSP was not different based on the rib-eye area and carcass weight in carcass than that from control. Back fat thickness tended to be thicker than control (P>0.05). Marbling score, texture and maturity for TP and DSP was abundantly to increase compared to control (P<0.003). There was significantly increment in supplemented $PROSOL^{(R)}$ (P<0.0001). The meat quality grade of control, TP and DSP were 2.94, 3.78 and 4.50, respectively. Related to this result, the auction price (carcass/kg) were gained significantly (P<0.003) from control (17,560), TP (18,586) and DSP (19,266 won) so which the monetary return was the highest in DSP and the differences was recognized between TP and DSP. Percentage over 1st grade appeared in control, TP and DSP were 55.4, 88.9 and 100.0%, respectively. These results supported the hypothesis that supplementation of emulsifier improve the marbling score and the carcass quality grade by increased digestibilities of the feed fat in Hanwoo steers in fattening period.

To determine the proper processing and storage conditions, physico-chemical, microbial and sensory properties of venison jerky under different dry times were measured during storage at $30^{\circ}C$ for 28 days. Samples were dried for 3 hr (T1), 4 hr (T2) and 5 hr (T3) at $75^{\circ}C$ in the smoke chamber, respectively. The pH of T1 was slightly lower than those of T2 and T3 as storage time increased. As dry and storage time increased, TBARS of T2 and T3 were significantly higher (p<0.05) than that of T1. In meat color, $L^*$ values of T3 showed slightly higher than those of T1 and T2, while at values were not clearly tendency by the passage of storage time. $b^*$ values of T2 and T3 were higher than that of T1. The water activity were significantly lower (p<0.05) in ,the order of T3$log_{10}$ CFU/g until 28 days and its number were accepted by sensory evaluation. In conclusions, T2 and T3 showed slightly high overall acceptability and lipid oxidative stability compared to T1 conditions. These results indicated that longer dry time ($4{\sim}5 hr$) of venison jerky would be better characteristics as compared to shorter dry time (3 hr) with increased storage time at $30^{\circ}C$.

Objective: We have studied the effects of acupuncture and low level He-Ne laser therapy(LLLT) at $SI_3$, $BL_{40}$ on the tibial, sural nerve injury due to sports-damage or traffic accident and L5 spinal nerve ligature model like general herniation of nucleus pulposus(HNP) in a rat of neuopathic pain. Methods: A model of neuropathic pain was made by injuring tibial nerve and sural nerve while common peroneal nerve was maintained. Also, it was made by isolating left 5th lumbar spinal nerve. Three weeks after the neuropathic surgery, acupuncture and LLLT was injected at $SI_3$,$BL_{40}$ one time a day for one week. LLLT was divided three groups, that is LLLT-1(5mW), LLLT-2(10mW) and LLLT-3(30mW). After that, we examined the withdrawal response of neuropathic rats' legs by Von frey filament and acetone stimulation. And also we examined c-Fos, Nocieptin and KOR-3 in the midbrain central gray of neuropathic rats. Results: As we have observed the effect of mechanical allodynia, LLLT-3 group were diminished on 4 day, 5 day, 6 day and 7 day in the resection model compared with control model, LLLT-1 group were diminished on 5 day, LLLT-2 group were diminished on 3 day and 6 day, LLLT-3 group were diminished on 3 day, 4 day, 5 day, 6 day and 7 day in connected model compared with control group. As we have observed the effect of cold allodynia, LLLT-3 group were diminished on 7 day in the resection model compared with control model, LLLT-1 group were diminished on 6 day, 7 day, LLLT-3 group were diminished on 7 day in connected model compared with control group. As we have observed the effect of activity of c-Fos in the central gray part, LLLT-3 were diminished in resection model compared with control group, LLLT-1 group were diminished in connected model compared with control group. As we have observed the effect of activity of Nociceptin in the central gray part, resection model were not increased compared with control group, LLLT-1 group and LLLT-3 group were increased in connected model compared with control model. As we have observed the effect of activity of KOR-3 in the central gray part, resection model were not increased compared with control group, LLLT-3 group were increased in connected model compared with control model. Conclusions: We have noticed that LLLT-1 and LLLT-3 group have more controllable effect than acupuncture group. This study can be used in clinical therapy for neuropathic pain. But it is not reliability that Nociceptin and KOR-3 have effectively to control pain. Therefore We have to follow up about that.
