This study was designed to evaluate the analgesic effect of bee venom (BV) Acupuncture into different treatment points, Chok-samni (ST36) and blank loci of the gluteal muscle and back. We investigated the changes in formalin-induced pain behavior according to the pretreatment with different concentrations of BV, thirty minutes before the formalin injection. The results were summarized as follows: 1. The formalin-induced pain behavior was suppressed by pretreatment with BV into Chok-samni (ST36) in a dose dependent manner. During the early phase, 0.08mg/kg of BV showed a statistically significant suppression in the formalin-induced pain behavior. Moreover, 0.008mg/kg, 0.016mg/kg, and 0.08mg/kg of BV, except 0.0016mh/kg of BV, had significant suppresive effects on the formalin-induced pain behavior during the late phase. Therefore, these data indicated that the suppressive effect of BV acupuncture on the formalin-induced pain behavior was stronger in the late phase rather than the early phase 2. In order to investigate the analgesic effect of BV acupuncture into different treatment points, the experimental animals were divided into three groups: Chok-samni (ST36) group, gluteal group and back group. In the Chok-samni (ST36) group, the formalin-induced pain behavior during all the phases was significantly reduced as compared with that of the back group. However, as compared with that of the gluteal group, the formalin-induced pain behavior in the Chok-samni (ST36) group was decreased only in the late phase, not in the early phase. The formalin-induced pain behavior in the gluteal group was significantly reduced as compared with that of the back group in the late phase, not in the early phase. We suggested that the analgesic effect of BV acupuncture into Chok-samni (ST36) was most effective among Chok-samni (ST36), gluteal, and the back groups in formalin-induced pain behavior.

비만의 원인이 되는 고지방식이 섭취는 체내에서 과다한 지질 축적 및 염증 반응을 유도한다. 본 연구에서 고지방식이로 비만이 유도된 C57BL/6 동물 모델에서 흑양파식초 섭취가 미치는 효과에 대해 알아보기 위해 흑양파즙 및 흑양파식초를 각각 6주간 투여하였다. 고지방식이를 유도한 HFD군은 정상 식이를 섭취한 NC군에 비해 체중 및 장기 무게가 증가하여 비만이 유도되었음을 확인하였다. 반면 흑양파식초를 투여한 HFD + BV군은 HFD군에 비해 체중 및 장기 무게를 유의적으로 감소시켰다. 또한 흑양파즙 및 흑양파식초를 각각 투여한 군은 HFD군에 비해 혈청 총 콜레스테롤 및 중성지질 수치를 개선시켰다. 뿐만 아니라, 흑양파식초 투여군은 HDL 콜레스테롤 및 LDL 콜레스테롤 수치를 유의적으로 개선시켜 고지방식이로 손상된 지질대사 개선 효과를 확인하였으며, 부고환 지방 및 간 조직에서 지방세포의 수와 크기를 감소시켰다. 흑양파식초의 비만개선 작용 기전을 확인하기위해 간 조직 내에서 adipogenesis 및 염증 관련 단백질 발현 측정 결과, 흑양파즙 및 흑양파식초 투여군은 HFD군에 비해 adipogenesis 및 염증 관련 인자를 감소시켰다. 특히 흑양파식초 투여는 흑양파즙 투여에 비해 지방생성에 관여하는 단백질 억제 효과가 더욱 우수하였다. 따라서 본 연구에서 흑양파식초 투여는 고지방식이로 비만이 유도된 동물모델에서 adipogenesis 관련 단백질 발현 억제를 통해 비만을 개선시킴을 알 수 있었으며, 항비만 기능성 식초로 활용 가능성이 있는 것으로 사료된다.

Cirsii Japonici Herba(CJ) is a wild perennial herb found in many areas of Korea as well as China and Japan, which has been used to treat bleeding and inflammation. Silibinin is the main flavonoid extracted from milk thistle (Cirsii Japonici Herba). It exhibits potent antioxidant activity and anti-inflammatory effect. In this study, the effect of CJ and silibinin extract on lipopolysaccharide-induced inflammation was investigated using MTS assay, RT-PCR, western blot, and nitric oxide detection on mouse BV2 microglial cell lines. In the present results, CJ and silibinin extract suppressed nitric oxide production by inhibiting the lipopolysaccharide-stimulated enhancement of COX-2 and iNOS gene expression in BV2 cells. Moreover, CJ and silibinin also repressed some lipopolysaccharide-induced signaling molecules. Importantly, catalase-induced COX-2 and iNOS expression needed activations of $NF-{\kappa}B$, PI3K/Akt, and MAPK, which were important for the transcriptional up-regulation of COX-2 and iNOS. CJ and silibinin interaction on BV2 cells down-regulated $NF-{\kappa}B$-dependent proinflammatory cytokine (IL-2,IL-6) expression. They are involved in the regulation of inflammatory responses. These data shows that CJ and silibinin exerts anti-inflammatory and analgesic effects, probably by suppression of COX-2 and iNOS synthase expression in BV2 microglial cells.

Objectives The purpose of this study is to evaluate the safety of Non-toxic bee venom (BV) and observe VAS change before and after Non-toxic BV treatment in pain patients. Methods We surveyed the clinical practitioners who treated with Non-toxic BV in pain patients who visited the Korean medical clinic. The questionnaire survey was conducted for clinical practitioners who agreed to participate after hearing the explanation for the purpose and characteristics of the questionnaire. Patients in the questionnaires were reviewed based on their medical records from July 1, 2016 to October 28, 2016. Results We received 445 cases and selected 403 cases finally. 2 cases, however, were not able to continue treatment for 3 weeks and were eliminated. Depending on when the pain occurred, we divided the 401 cases into three groups (Acute, Subacute, Chronic group). In all groups, VAS scores were significantly decreased after treatment. Adverse reactions following Non-toxic BV treatment had occurred was 16 cases (3.60%). Except for 3 cases with hives, most of adverse reactions were mild or moderate and were not in need of extra treatment. The total safety of treatment for 3 weeks was mostly safe. The number of cases discontinued treatment was 42 cases (9.44%). Most of these cases, treatment was stopped for personal reason unrelated to the Non-toxic BV treatment. Conclusions These results suggest that the Non-toxic BV treatment has no serious adverse reactions and is a relatively safe treatment. Further studies are needed to prove the efficacy and clinical safety of Non-toxic BV treatment.

Herniation of intervertevral disc(HIVD) is the most common disease causing low back pain. Acupuncture, electroacupuncture and moxibustion has been used for treatment of HIVD. Bee venom (BV) also has been traditionally applied to relieve pain. Recently, it has been reported that BV is effective in treating HIVD. But more objective methods were required to assess the efficacy of BV on HlVD. So we assessed of BV-acupuncture effect on herniated disc patients by use of rating scale for low back pain. We researched 22 patients who were treated at Department of Acupuncture & Moxibustion, Kyung Hee Medical Center from January 1999 to June 1999. The patients were diagnosed by MRI as having a herniated disc. The results of treatment using rating scale for low back pain in HIVD showed that $43.77{\pm}14.39$ point of pre-treatment score and $84.5{\pm}3.97$ point post-treatment score. The improvement index showed $0.43{\pm}0.15$. Especially, clinical score of neurologic deficits showed most highest improvement index of $0.7{\pm}0.45$. Assessment of BV-acupuncture Effect by MRI finding were showed that protruded disc and extruded disc got more higher improvement index than bulging disc. Among 22 patients, satisfactory assessment of BV-acupuncture effect showed that 15(68.2%) were excellent, and 7(31.8%) were good. The result suggest that BV-acupuncture is good method for treatment of HIVD.

Objective : Bee venom (BV) has traditionally been used in Oriental medicine to relieve pain and to treat inflammatory disease such as rheumatoid arthritis (RA). Autoimmunity to type II collagen (CII) may involve in the pathogenesis of RA. This study was performed to evaluate the effect of BV on type II collagen induced arthritis (CIA) with the naked eye, a immunohistochemical method and the examination of histology. Method : Male mice were immunized by subcutaneously injection of an $200{\mu}g$ emulsion mixed with bovine CII and complete Freund's adjuvant (CFA) twice for two weeks. In the control group, normal saline was injected, and in the experimental group, BV was applied. Result : The incidence of arthritis, the mean arthritis index and the number of the arthritic limbs of the BV group were all significantly lower than those of the control group. Among the pro-inflammatory cytokines, the production of $TNF-{\alpha}$ in the BV group was also suppressed compared with the control group, but $IL-1{\beta}$ was not. The examination on the histopathology of joints of CIA mice showed the effect of Bee Venom Herbal Acupuncture on the arthritis. Conculusion : Treatment with BV resulted in inhibition of development of arthritis and immune responses to CII.
