Objective : To broaden understanding about relationship between Meridian Tendino-musculature and muscles in a lumbar area and to evaluate the effect of Meridian Tendino-musculature acupuncture and release therapy on acute lumbar sprain. Materials and Methods : From Oct. 1st, 2000 to Mar. 31th, 2001, 692 outpatient's chart of Kyung Won University Hospital were reviewed. Out of them, 39 outpatients were selected. they had low back pain, were diagnosed with acute lumbar sprain, showed only straightened curvature on lateral view of lumbar spine X-ray and get the Tendino-musculature acupuncture and release therapy. Results : 1. On patients' first visit, 72% had GrIII and Gr.IV predominantly. 2. Major muscles related with low back pain were divided into two groups. One was Quadratus lumborum group and the other was Rectus abdominis group. In the correlation with Meridian Tendino-musculature, the former was mainly related with Chok-taeyang(B) and slightly related with Chok-soyang(G), Chok-taeum(SP), the latter was mainly related with Chok-taeyum(SP), Chok-yangmyong(S) and slightly related with Chok-taeyang(B), Chok-soyang(G). 3. In the evaluation of treatment effect, Exellent was 27(69%), Good was 10(6%), Fair was 2(5%) and Bad was 0(0%). Fair rate reached 100% eventually. 4. Most of Gr.Ⅲ, Gr.Ⅳ patients who had severe conditions that almost every R.O.M. was limited and Milgram test positive was shown on the physical examination, were fully recovered and lived normal daily life without admission by Meridian Tendino-musculature acupuncture and release therapy within 3 to 5, 4 to 7 days, respectively, since they had started to get their outpatient treatment. 5. Two patients was troubled with pain induced, by twitching response and acupuncure stimuli, which lasted around acupunctured muscle for about a day after treatment, so they coudn't endure the pain and quitted treatment in spite of Fair condition. conclusion : Meridian Tendino-musculature acupuncture and release therapy was found to be helpful to patients who wish to recover from their back pain induced by acute lumbar sprain as soon as possible, but the treatment actually had some problems to be overcome such as pain during or after the treatment. therefor, in order to make this treatment method more available, we should pay more attention to improving treatment appliance and acupuncture technique.

Objective : The purpose of this case is to report the improvement after treatment about a patient with meralgia paresthetica. Methods : We treated the patient with acupuncture therapy and Herbal medication from 11th October 2004 to 15th October 2004 by evaluating femoral function with VAS score and R.O.M of femur joint. Results : After 5 times of treatment, this patient achieved excellent outcome following the technique, showing that clinical symptom as like heating sense, edema and pain was disappeared, VAS changed from 10 to 1 and there was no limitation of ROM of femur. Conclusions : Meralgia paresthetica is a symptom complex that includes numbness, paresthesias, and pain in the anterolateral thigh, which may result from either an entrapment neuropathy or a neuroma of the lateral femoral cutaneous nerve(LFCN). Oriental medical treatment for meralgia paresthetica resulted in satisfactory results by diminishing the symptoms progressively during the five days of treatment. Differential diagnosis was based on careful physical examination. More research of meralgia paresthetica is needed.

Introduction : Recent studies Suggested that there is a strong correlation between acupuncture stimulation and its related cortical activation. Anther study showed that either positive or negative BOLD effects could be observed depending on anatomical structure in acupuncture stimulation. In ttis study, we investigated a new acupoint $KI_6$ (照海), which was known as motor-related acupoint and obtained an evidence that the stimulation of $KI_6$ resulted in either negative or positive BOLD response to stimulation. Methods & Results : 1. Subjects and paradigms : Two separate stimulation paradigms were performed on five healthy (aged 22-23 yrs) in this study. First, the paradigm of acupuncture stimulation was that the acupuncture needle was inserted in acupoints $KI_6$, which is located in lateral side of the foot and then continuously twisted(補瀉를 除外한 捻轉法) for 70 seconds for 10 cycles of activation. During rest period (70 seconds), the needle was completed removed from acupoint. Total 60 cycles were performed and 10 images were obtained per cycle. Second, nonacupoint was randomly selected and the same paradigm was performed as acupoint stimulation. The stimulation protocol comprised 10 cycles of alternating. activation and rest (10 images per cycle). Total 60 cycles were performed and each cycle take about 1.5 sec for motor task. Subjects take an at least 15 minutes break before starting anther paradigm. 2. fMRI mapping : Multi-slice functional images were obtained on a 1.5T Magnetom Vision MRI scanner (Simens Medical, Erlangen, Germany) equipped with high performance whole-body gradients. The BOLD T2 * - weighted images were acquired with acho planar imaging sequence (TR = 1.2 sec, TE = 60 msec, and flip angle = $90_{\circ}$). The other sequence parameter are : FOV = 210 mm, matrix=$64{\times}128$ or $64{\times}64$, slice number=10 and slice thickness = 5 or 8 mm. the anatomic images were obtained with Spin-echo T1-weighted images. The resulting images were then anaiyzed with STIMULATE (CMRR, U. of Minnesota) to generate functional maps using a student T-test (p < 0.005) and cluster analysis. Both positive and negative response were evaluated. Conclusions : We have observed the activation of the motor cortex by stimulating motor-related acupoint ($KI_6$). Among five subjects, negative BOLD response was shown in four and positive response in one. All subjects showed positive response to conventional finger flexion-extension task. To understand the detailed mechanisms of correlation between acupuncture stimulation and BOLD fMRI changes and two typs of response, further study strongly required.

Objective: This paper aimed to understand influences on EEG conducting acupuncture stimulation, by comparing the changes in the acupoints on the body before and after normal people are treated with acupuncture at PC9 and TE3, which are referred to as Wood points(木穴), and PC5 and TE1, which are referred to as the Metal points(金穴) among the five shu points of Yin pericardium Meridian and Yang Triple Energizer Meridian. Methods: The study was performed on 30 healthy female volunteers in their 20's. EEG was measured for 5 minutes before acupuncture stimulation was conducted on PC9, TE3, PC5 and TE1. During 20 minutes of acupuncture treatment, the same items were continuously measured to find out whether there were any changes in them, and they were measured for 5 minutes after removing the acupuncture needles in order to implement a comparative analysis. Results: Comparision of EEG data before and after the treatment at PC9 shows no significant differences in all wave. Compared with the pre-acupuncture period at TE3, $\delta-\theta$ wave decreased significantly (P<0.05) during the acupuncture stimulation periods. Compared with the pre-acupuncture period at PC5, $\delta-\theta$ wave and high $\alpha$ wave increased significantly (P<0.05) during the acupuncture stimulation periods. And Mid $\beta$ wave and high $\beta$ wave decreased significantly (P<0.05) during the acupuncture periods and the post acupuncture periods. Compared with the Pre-acupuncture period at TE1, $\delta-\theta$ wave, $\theta$ wave and high $\alpha$ wave increased significantly (P<0.05) during the acupuncture stimulation periods. And Low $\beta$ wave decreased significantly (P<0.05) during the acupuncture periods. Conclusion: When acupuncture stimulation was performed on PC9 and TE3, referred to as the "Wood points", brain waves were stabled, while when acupuncture was performed on PC5 and TE1, called the "Metal points", a brain was waked. From the findings of this study, we hypothesize that the wood properties, from which growing starts in all things, are related with fast waves of EEG, and the metal properties, which stabilize and converge in all things, are related with slow waves of EEG.

Objectives : In the acupuncture treatment of Korean Medicine, the Tonifying or Purging depending on how many times the needle is rotated has been used widely. However, there is little evidence about the optimal number of rotation. This study, therefore, was aimed to investigate the optimal number of rotation. Methods : Heart rate variation was measured before and after exercise in 20 healthy adults. Acupuncture was performed at PC6 immediately after exercise according to the protocol of each group without remaining. Pre-exercise and post-exercise measurements were compared and the rotation number that produced statistically significant difference was investigated. Results : Significant differences were found in the heart rate variation and R-R interval Average, between non-rotation group (control) and both of 15 times rotation group of tonifying and 6 times rotation group of purging. Conclusions : Significantly effective number of rotation in the effect of PC6 on the HR and RRAv was 15 times in the tonifying and 6 in the purging respectively.

Objectives : The purpose of this study is to review needling depth and location of LU7, BL62 and KI6 by the medical classics' records. Methods : 1. We researched the medical classics describing LU7, KI6 and BL62, and reorganized data about the location and needling depth. 2. We compared the medical classics' records on LU7, KI6 and BL62 with description of WHO standard acupuncture point location. 3. We reviewed different location and needling depth of LU7, BL62, and KI6 recorded in the medical classics with the anatomical structure. Results : 1. The common needling depth of LU7 is about 0.2 chon. But in some medical classics, the depth of LU7 is 0.8 chon. Needling depth of LU7 varied depending on the patient's hand posture. In the 'half-up' position with the thumb upward, it is possible to stimulate acupuncture on LU7 by 0.8 chon because there is a space between the tendons. 2. In WHO standard acupuncture point location, the locations of BL62 and KI6 are just below the lateral and medial malleolus. But in some medical classics, the locations of BL62 and KI6 are between the bones and muscles below the malleolus. In the locations between the bones and muscles below the malleolus, it is possible to stimulate acupuncture on BL62 and KI6 by penetrating acupuncture because there is no bone structure. Conclusions : 1. By the 'half-up' position with the thumb upward, it is possible to stimulate vertically acupuncture on LU7 by 0.8 chon. 2. By the locations of BL62 and KI6 between the bones and muscles below the malleolus, it is possible to stimulate on BL62 and KI6 by penetrating acupuncture.

Laser stimulation has been widely studied and used in clinic. However, electrical response by laser stimulation on meridians has not been investigated. In this study, we compared electric potential of laser and acupuncture stimulation on meridians. We measured electric potential variation at acupoints(Samgan(LI3) and Hapgok(LI4)) on Large Intestine Meridian. In laser stimulation results, average peak electric potential is very low($7.53{\pm}3.44{\mu}V$) for before and after stimulation. However, acupuncture stimulation was performed in ground connection condition and resulted in huge variation of average peak electric potential($2.65{\pm}1.53mV$). That is, the intensity and pattern of electric potential were dependent on the ground connection condition and individual. Also, the electric potential pattern was very similar to the pattern of electric charge and discharge of capacitor. The acupuncture stimulation using a insulating needle resulted in lower average peak electric potential variation($0.25{\pm}0.16mV$) than that of acupuncture stimulation. It might present little electrical response of acupuncture stimulation using insulating needles. In point of electrical response, the laser stimulation was determined to be no acupuncture effect at meridian. Acupuncture stimulation seems to be most effective method to induce electrical response at meridians. The procedure and effect of acupuncture might be considered as energy consensus phenomenon by transportation of bio-ion charge between a practitioner and patient.

To investigate the maturational and development competece of porcine oocytes of different diameter groups, oocytes were obtained by aspiration from slaughterdhouse ovaries. After washing three times in NCSU23 medium, each cumulus-oocyte complex was transferred into a $8{mu}ell$ drop of the maturation medium (one oocyte per drop) under paraffin oil. The diameter without zona pellucida of oocytes was measured with micor-calibrator (Mikrometer, E. Leitz) on a screen connected to a VCR on an inverted microscope $(200\times)$. After being measured, the oocytes were divided into 6 groups according to their diameter size : <105, 105 to < 110, 110 to < 115, 115 to < 120, 120 to < 125 and > $125{\mu}{\textrm}{m}$, and in vitro maturation (IVM), fertillzation (IVF) and production (IVP) of oocytes / embryo was performed. The rates of in vitro maturation on oocytes in the greater 105 ${\mu}{\textrm}{m}$ size groups(91.8~100%) were significantly (P<0.05) higher than in the < 105 ${\mu}{\textrm}{m}$ group(66.7%). The rates of sperm penetration were significantly (P<0.05) low in < $105{\mu}{\textrm}{m}$ group (50.0%) than others groups (81.6~85.5%). But the plyspermic fertilization rate was significantly (P<0.05) higher in < $110{\mu}{\textrm}{m}$ oocytes groups than in the $110\leq{\mu}{\textrm}{m}$ size groups. The rates of cleavage and development to blastocysts rose as oocytes diameter increased, however, while oocytes over $120{\mu}{\textrm}{m}$ in diameter failed to develop to blastocysts. There results suggest that porcine oocytes have acquired full meiotic competece at a diameter of $105{\mu}{\textrm}{m}$ but not yet attended full development competence to blastocyst and that oocytes have acquired full development competence at a diameter of $110{\mu}{\textrm}{m}$.

The present study was carried out to examine the effect of cysteamine in vitro maturation (IVM) of porcine oocytes and development of porcine IVM/IVF Embryos. The results were summarized as follows : 1. The rates of nuclear maturation, penetrated oocytes, pronuclear formation, polyspermic oocytes and mean numbers of the penetrated sperm were not different in NCSU23 maturation medium with 0, 25, 50 and 100 $\mu$M cysteamine (P〉0.05). 2. The rates of blastocyst formation at day 7 after in vitro fertilization in 0, 25, 50 and 100 $\mu$M cysteamine were 17.9$\pm$6.1, 17.4$\pm$6.3, 24.2$\pm$1.9 and 16.9$\pm$2.0%, respectively. And the total cells were 30.7$\pm$2.4, 34.9$\pm$2.8, 39.6$\pm$2.3 and 36.8$\pm$3.6, respectively. Fifty $\mu$M cystealnine group was significantly higher than those of any other treatment groups (P＜0.05). 3. The ratios of ICM/total cells in 20~40% category were 20.5, 41.6, 19.5 and 31.5%, respectively. Twenty five $\mu$M cysteamine group was higher than those of other groups. 4. The rates of blastocyst formation at day 7 in the NCSU-23 culture medium of porcine IVF-produced embryos with 0, 25, 50, and 100 $\mu$M cysteamine were 16.0$\pm$0.2, 13.6$\pm$1.7, 25.0$\pm$0.8 and 15.7$\pm$4.5%, respectively. And the total cells were 27.0$\pm$3.7, 36.1$\pm$4.8, 34.0$\pm$3.8 and 25.2$\pm$4.4, respectively. Fifty $\mu$M cysteamine group was significantly higher than those of any other treatment groups (P＜0.05). 5. The ratios of ICM/total cells in 20~40% category were 53.8, 30.0, 16.6 and 11.1%, respectively. The addition groups of cysteamine were lower than those of control group. In conclusion, these results suggested that the addition of 50 $\mu$M cysteamine in the IVM medium and 25~50 $\mu$M cysteamine in IVC medium were effective on the blastocyst formation and total cells of blastocysts.
