Objectives : This study was to investigate the effect of high frequency electroacupuncture at $ST_{36}$ acupuncture point on the Complete Freund's Adjuvant (CFA) induced rat arthritis pain model. Methods : Arthritis was induced by intradermal injection of CFA into base of tail. Experimental groups were divided into 4 groups; Normal, Control and Jok-Samri ($ST_{36}$) and Non-Acupuncture point (NA). Normal group, non-arthritic group, was injected with normal saline，and the others groups were injected CFA. $ST_{36}$ group was treated by 120 Hz electroacupuncture at $ST_{36}$ acupuncture point, and NA group was treated by 120 Hz electroacupuncture at non-acupuncture point. Each groups were evaluated by the change of c-fos positive neurons in periaqueductal gray (PAG) and hippocampus by using an image analyzer and a microscope. Results: - In the PAG region, the number of fos-positive cells in the $ST_{36}$ group ($42.37{\pm}5.08$) were significantly (p<0.05) decreased compared with the control group ($64.56{\pm}6.35$). - In the PAG region, the number of fos-positive cells in the NA group were meaninglessly decreased compared with the control group - In the Cornu Ammonis(CA)l region of hippocampus, the number of fos-positive cells in the $ST_{36}$ group ($7.00{\pm}1.08$) and NA group ($5.56{\pm}2.01$) were significantly (p<0.05) decreased compared with the control group ($13.81{\pm}1.24$). - In the dentate gyrus region of hippocampus, the number of fos- positive cells in the $ST_{36}$ group ($10.75{\pm}0.98$) and NA group ($6.56{\pm}0.78$) were significantly (p$26.45{\pm}1.82$). Conclusions : It is expected that high frequency electroacupuncture can be used a treatment of arthritic pain.

The present study was investigated the neuroprotective effects of acupuncture at ST36 on learning and memory deficits after transient cerebral ischemia in a gerbil model. The animals were randomly divided into three groups (n=7 in each group): the sham operation group (SHAM), ischemia-induced and ST36 acupuncture group (ISC + ST36), and the ischemia-induced and Tail-acupuncture group (ISC + TAIL). For the acupuncture stimulation, stainless steel needles, 0.3 mm in diameter, were inserted bilaterally into the ST36 locus or the tail and stimulated for 1 min/day for 14 days. Using the Morris water maze test, the animals were tested on spatial learning and memory. In addition, the effects of acupuncture on memory storage and the choline acetyltransferase (ChAT) activity, in the hippocampal CA1 area, were investigated by ChAT immunohistochemistry. Transient cerebral ischemia produced impaired performance on the MWM test (DAY 5: p<0.01 and retention test: p<0.05) and severely decreased ChAT immunoreactivity in the CA1 hippocampal area compared to the SHAM group (p<0.05). However, improved learning and memory were observed (DAY 5: p<0.05 and retention test: p<0.01) as well as a significantly reduced loss of ChAT immunoactivity in the hippocampal CA1 region (p<0.001) after acupuncture stimulation at ST36 were observed. These results show that acupuncture at ST36 ameliorated the learning and memory deficits at least in part through the cholinergic system. The findings of this study provide potential data that acupuncture is useful for the treatment of some of the behavioral impairs of transient cerebral ischemia.

Carbapenem-resistant Klebsiella pneumoniae (CRKP) is emerging as a worldwide public health threat. Recently, Klebsiella pneumoniae carbapenemase-2 (KPC-2)-producing sequence type (ST) 307 was identified main clone of CRKP, and dissemination of ST307 was reported in South Korea. This study examined the molecular characteristic and antimicrobial resistance pattern of 50 CRKP isolated from a tertiary hospital in Daejeon, from March 2020 to December 2021. Epidemiological relationship was analyzed by Multilocus sequence typing (MLST) and antimicrobial susceptibility test was determined using disk-diffusion method. PCR and DNA sequence analysis were performed to identify carbapenemase genes. CRKP infections were significantly more frequent in males and the patients aged ≥ 60 years. Among the 50 CRKP isolates, 46 isolates (92.0%) were multidrug-resistant (MDR), and 44 isolates (88.0%) were carbapenemase-producing K. pneumoniae (CPKP). The major carbapenemase type was KPC-2 (36 isolates, 72.0%) and New Delhi metalloenzyme-1 (NDM-1) and NDM-5 were identified in 7 isolates (14.0%) and 1 isolate (2.0%), respectively. In particular, 88.9% (32/36) of KPC-2-producing K. pneumoniae belonged to ST307, whereas 87.5% (7/8) of NDM-1,-5-producing K. pneumoniae belonged to non-ST307. These results suggest that proper infection control and effective surveillance network need to prevent not olny the spread of ST307, but also the development of non-ST307.

Objectives: Single colorectal instillation of trinitrobenzenesulphonic acid (TNBS) causes a dose-dependent increase of visceral motor response (VMR) and severity of inflammation. In this study we compared the effects of electroacupuncture in the different acupoints in the acute colitis induced by TNBS intracolonic injection in rats. Methods: In Male Sprague-Dawley rats, weighing $250{\sim}400g$, a single colorectal administration of TNBS 5mg/kg and 50% ethanol under isoflurane anaesthesia after an overnight fast. Electrodes for electromyography (EMG) recording were stitched into the external oblique musculature under general anesthesia. Acupoints of LI4, ST25, or ST36 were stimulated by electroacupuncture, respectively. The balloon was inserted intra-anally and visceral motor response (VMR) to colorectal distensioin (CRD) was quantified with an EMG recording system. Results: At an observation of the visceral hyperalgesia in the day-time series, the visceromotor response increased significantly 3 days after TNBS intra-rectalcolonic injection in rats. Electroacupuncture on either ST25 or ST36 suppressed the visceromotor response to colorectal distension, but not LI4, at 3 days after TNBS injection. Pretreatment of naltrexone (10 mg/kg, i.p.), opioids antagonist, inhibited the VMR suppress of 10Hz EA to ST36 but not phentolamine (5 mg/kg, i.p.). Pretreatment of either naltrexone or phentolamine inhibited effects of 10Hz EA to ST25. Conclusions: Data show that EA at either ST25 or ST36 potently inhibits hypersensitivity of colorectum after TNBS induced colitis and is differently mediated through the endogenous opioid system and adrenergic system.

Objectives : The aim of the study is to find out whether effect of acupuncture is depending on the diameter of needle, which is a possible component of dose of acupuncture needling. Methods : To compare acupuncture effects in different diameters of needle, we measured the changes in muscle fatigue recovery using surface electromyogram(sEMG) in healthy 8 volunteers. Muscle fatigue was induced by 20 times sit-up for 1 min. Immediately after induction of muscle fatigue, acupuncture needle was inserted into ST36 or ST25 for 10 min by diameters of 0.20 mm, 0.30 mm, or 0.40 mm needles. The sEMG recording was followed by acupuncture for 30 min. As a control group, sEMG was recorded for the same period at rest after muscle fatigue induction. Results : In both of ST 36 and ST 25, stimulation with 0.4 mm diameter needle showed significant rapid recovery followed by short period of muscle fatigue increase. Stimulation with 0.2 mm diameter significantly suppressed the increase of muscle fatigue. Conclusions : These data suggest that acupuncture effect is, at least in part, dependent on diameter of needle. Therefore, diameter of needle is also considered to achieve effective outcome of acupuncture.

Objectives & Methods: We investigated 36 books to study etiology, pathology and acupuncture & Moxibustion treatment of Gak-Gi Result and Conclusion 1. Gak-Gi is a disease of legs. In the past, it was called Wan-poong(緩風) or Gueol(厥). Currently it is divided into two kinds; the Seup-Gak-Gi(Damp Gak-Gi) in which the legs swell; The Gun-Gak-Gi(Dry Gak-Gi) in which the legs do not swell. 2. Gak-Gi may be caused by exogenous wind, coldness, dampness and Excess of phlegm or damp-heat. It also can be caused by weakness of vital energy(Myungmoon fire;命門火), kidney Yin deficiency and vital energy deficiency in the Stomach and Spleen. 3. Gak-Gi-Pal-Hyul(Eight acupoints for Gak-Gi; 脚氣八穴) are GB31(Poonsi; 風市), ST32(Bok-to; 伏兎), ST35(Dok-bi; 犢鼻), Nae-seul-an(Extra point; 內膝眼), ST36(Chok-samni; 足三里) ST37(Sang-goho; 上巨虛) ST39(Hagoho; 下巨虛) GB41 (Choc-imup; 足臨泣) 4. Treatment plans for Gak-Gi are removing the exogenous wind, coldness and dampness, regulating meridians, alleviating the pain and swelling, more importantly, tonifying vital energy and nourishing Spleen and Stomach. 5. Three out of Eight acupoints for Gak-Gi, ST36(Chok-samni; 足三里), ST37(Sang-goho; 上巨 虛), ST39(Hagoho; 下巨虛) are Lower sea points of Fu organs( Stomach, Large Intestine, Small Intestine). Five out of Eight acupoints for Gak-Gi, ST32(Bok-to; 伏兎), ST35(Dok-bi;犢鼻) are onthe Stomach meridian, and Nae-seu1-an(Extra point; 內膝眼) is on the Spleen meridian. This result indicates that regulation of Middle-cho(中焦) is important in the treatment for Gak-Gi.

Objectives : The objective of this study was to investigate the effects of Zingiberis Rhizoma Pharmacopuncture(ZP) at GB30 and ST36 in neuropathic pain induced SD rats by the block of Transient Receptor Potential Vanilloid 1(TRPV1). Methods : Neuropathic pain in rats was induced by tibial and common peroneal nerve transection of right leg. The rat subjects were divided into 6 groups : normal(Nor, n=5), control(Con, n=5), neuropathic pain plus 2 mg/kg ZP injection at GB30 and ST36(ZP-A, n=5), 10 mg/kg ZP(ZP-B, n=5), 20 mg/kg ZP(ZP-C, n=5) and 0.45 mg/kg Tramadol(Tra, n=5). Three days after the surgery, injections were administered once a day for 17 days. Withdrawal response of neuropathic rats' legs were measured by stimulating the paw of Right leg with von frey filament, acetone and radient heat on day 3, 7, 11, 15, 19 after surgery. After all treatments were completed, c-Fos in the midbrain central gray and TRPV1 & TRPA1 of DRG(L5) were analyzed. Results : Groups ZP-B and ZP-C showed a meaningful decrease in the withdrawal response of mechanical allodynia, thermal hyperalgesia and cold allodynia compared to the control group(p<0.05, p<0.01, p<0.001). Groups ZP-B and ZP-C showed a meaningful decrease in the expression of c-fos and TRPV1 protein level compared to the control group(p<0.05, p<0.01, p<0.001). Conclusions : These results suggest that Zingiberis Rhizoma Pharmacopuncture at GB30 and ST36 could decrease mechanical & cold allodynia and thermal hyperalgesia by block the TRPV1 on the model of neuropathic pain.
