Objectives : The purpose of this study is to review which acupoints and meridians are selected to treat visceral pain in articles published in international journals and to investigate quality of reporting acupuncture intervention according to the STRICTA guidelines. Methods : Electrical and hand search were conducted in PubMed, EMBASE, MEDLINE, and Cochrane Library for acupuncture studies on visceral pain in human and animals. Reporting quality of intervention was evaluated using the revised STRICTA guidelines. Results : We included 51 articles (7 clinical studies and 44 animal studies) in this study. The most frequently adopted meridians and acupoints were Stomach meridian, Spleen meridian, Conception Vessel meridian, and ST36, CV4, SP6, LI4, PC6, SP9, ST25, ST37 in clinical studies. In animal studies, Stomach meridian, Conception Vessel meridian, Pericardium meridian and ST36, ST37, CV12, PC6 were most frequently used. Animal studies showed significantly lower quality of reporting compared to clinical studies. According to the analysis on the effect of year of publication of articles, announcement of STRICTA guidelines did not improve the quality of reporting for studies on visceral pain. Conclusions : These results suggest that both proximal and distal acupoints based on meridian theory were used to study the underlying mechanisms of visceral pain both in human and animal studies. Guidelines of acupuncture intervention reporting for animal study is necessary to improve the quality of evidence, and it will also allow us the integrative understanding of the mechanisms and clinical effects of acupuncture treatment in human and animal.

Sialolithiasis is the common pathology of salivary gland. The size of sialoliths vary from 1 mm to a few cm, but most of that are less than 10 mm. Large sialoliths (larger than 15 mm) are extremely rare. It is called Giant sialolithiasis or megalith. Symptom of the giant sialolithiasis is similar to that of regular sialolithiasis. First choice of treatment is removal of the stone. Many literatures reported various methods to remove the sialoliths. For this case report, we accidentally found the giant sialolith on the computed tomography taken for dental implant, and successfully removed the stone by minimal invasive surgical approach. Base on this result, we report this case with literature reviews.

Bisphosphonates are used effectively for many medical conditions, such as multiple myeloma, Paget's disease, osteoporosis, etc. However, recently, osteonecrosis of the jaw was observed in patients receiving long-term bisphosphonate therapy, including oral administration. This osteonecrosis is refractory, and complete recovery is not guaranteed despite a standard treatment protocol being established by many associations related to oral and maxillofacial surgery. The treatment outcome of oral bisphosphonate-related osteonecrosis of jaw (BRONJ) is reported with a review of the relevant literature.

Objectives : We studied anti-allergic effects of Cinnamomi Ramulus(CR) herbal acupuncture and Cinnamomi Ramulus extract. Methods : In vivo, animals were herbal-acupunctured with CR at both ST36s three times for 5 days. Then, we induced active systemic anaphylatic shock using compound 48/80 in ICR mice, and passive cutaneous anaphylaxis using anti-DNP IgE in Sprague Dawley rat. In vitro, we measured cell viability, ${\beta}$ -hexosaminidase release and the expressions of IL-4, TNF-${\alpha}$ and COX-2 mRNA in RBL-2H3 cells after treatment of various concentrations of CR extract. Results : In vivo, CR herbal acupuncture pretreatments at both ST36s inhibited compound 48/80-induced active systemic anaphylatic shock. Passive cutaneous anaphylaxis was inhibited by CR herbal acupuncture pretreatments at both ST36s and optional points. In vitro, CR extract treatments did not affect on cell viability and inhibited ${\beta}$-hexosaminidase release. CR extract treatments also decreased the expressions of IL-4, TNF-${\alpha}$ and COX-2 mRNA in RBL-2H3 cells. Conclusions : These results suggest that CR herbal acupuncture and CR extract should be beneficial in the inhibition of allergic inflammatory response.

Sasang Constitution Medicine(SCM)'s researches have been developed in many ways, especially Herbal medicine prescriptions and diagnosis. But there are no acceptable acupuncture theory for the Sasang Constitution. So We have tried to find the way for identifying each Sasang Constitution's acupuncture point on more reasonable methods. We studied that SCM acupuncture based on collecting Books of "Shanghanlun(傷寒論)", or Six-meridian pattern identification's acupuncture prescription. Selected books are "The Acupuncture and Moxibustion(침구학)", "Zhonghua Zhenjiuxue(中華鍼灸學)", "Zhenjiuxinchuan(鍼灸心傳)", "Shanghanlun Zhenjiupeixuexuanzhu(傷寒論鍼灸配穴選注)". So-eumin uses Conception Vessel's acupuncture points most frequently. And So-yangin and Tae-eumin use Bladder meridian and Stomach meridian's acupuncture points most. Moxibustion is used many times for So-eumin, especially at three Yin-Symptoms(三陰病). Orders for using frequencies of three Sasang constitutions' acupuncture points are: So-eumin uses ST36 CV12 CV4 most, So-yangin uses PC6 ST36 LI4 most, Tae-eumin uses ST36 LU7 CV12 most. Acupuncture for Sasang constitutions has been developed for many ways, but there are no generally acceptable theory. So we need to hold a committee for SCM and acupuncture specialist to establish acceptable and reasonable SCM acupuncture theory.

Acupuncture is the process of stimulating skin regions called meridians or acupoints and has been used to treat pain-related symptoms. However, the pain-relieving effects of acupuncture may be different depending on acupoints. In the present study, the effects of acupuncture on behavioral responses and c-Fos expression were evaluated using a formalin test in male Sprague-Dawley rats in order to clarify the analgesic effects of three different acupoints. Each rat received manual acupuncture at the ST36 (Zusanli), SP9 (Yinlingquan) or BL60 (Kunlun) acupoint before formalin injection. Flinching and licking behaviors were counted by two blinded investigators. Fos-like immunoreactivity was examined by immunohistochemistry in the rat spinal cord. Manual acupuncture treatment at BL60 acupoint showed significant inhibition in flinching behavior but not in licking. Manual acupuncture at ST36 or SP9 tended to inhibit flinching and licking behaviors but the effects were not statistically significant. The acupuncture at ST36, SP9, or BL60 reduced c-Fos expression as compared with the control group. These results suggest that acupuncture especially at the BL60 acupoint is more effective in relieving inflammatory pain than other acupoints.

Objectives : This article examines whether 'Samni', which appears 62 times in Dongui-Bogam: Treasured Mirror of Eastern Medicine, means Joksamni(ST36) or Susamni(LI10). Methods : After searching the sentences which include 'Samni' in Dongui-Bogam using Medical Classics Database, we checked the original reference of them to find clues to identification of Samni. As for the statements not identified by the original reference nor by Dongui-Bogam, we judged the meaning of Samni by comparing diseases of the statements with those of Joksamni or Susamni's treatment area. Acupoints used together with Samni were also taken into account. Results : Out of 52 statements, Samni in 25 statements turned out to be Joksamni after tracing the reference; 6 statements mention stomach, and 4 statements treat Samni as an acupoint of stomach meridian; in 12 statements, diseases belong to Joksamni's treatment area. Samni of the remaining 5 statements also seem to be Joksamni since the diseases of the statements are similar to those of Joksamni. It implies that Joksamni's treatment area has expanded over time. Conclusions : All Samni in Dongui-Bogam is Joksamni.

This experiment was carried out to evaluate general characteristics of the water quality, total coliform, fecal coliform and microflora at the St. 1 to St. 3 and St. 4 to St. 7. Eighty-four water samples were collected from the 7 stations from July 1988 to April 1990 (see Fig. 1) Range and mean value of the samples were as follows water temperature 2.0-29.9$^{\circ}$C, 16.3$^{\circ}$C pH 6.86-9.08, 7.62: electrical conductivity 54.85$\mu \mho$/cm, 4.300 m$\mho$/cm, 911.93 $\mu \mho$/cm : turbidity 0.9-36 NTU, 6.8 NTU, respectively. pH and electrical conductivity at St. 4 to St. 7 were higher than those at St. 1 to St. 3, but turbidity at St. 1 to St. 2 was 7 times higher than that at Sonagdong river area. The bacterial density of the samples ranged 91-110,000/100ml for total coliform. 21-15,000/100ml for fecal coliform. Specially, the geometric mean value of the St. 3 was 11,836 / 100ml for it leveled heavy contaminaiton. Predominant species among the 3,874 strains isolated form the samples were 30.6% Enterobacteriaceae, 14.7% Acinetobacter, 9.0% Aeromonas. 8.9% Neisseria, and 7.5% Vibrio.
