Purpose: Although an increased incidence of gallbladder (GB) stone formation after gastrectomy has been reported, its etiology remains uncertain. The goal of this study was to explore the incidence of gallstone formation after gastrectomy in gastric cancer patients and investigate the risk factors therein. Materials and Methods: Medical records of patients who underwent curative gastrectomy, performed by a single surgeon between August 2012 and December 2015 at the Asan Medical Center, were retrospectively reviewed. Baseline characteristics and surgical outcomes, including GB stone gallstone formation after gastrectomy, were analyzed. Results: Of 561 patients included in the study, 36 presented with GB stone formation after gastrectomy for gastric cancer. The incidence of gallstone formation was 6.4%. The mean interval between gallstone formation and gastrectomy was 21.9 months. In multivariate analyses, the incidence of gallstone formation increased in patients 63 years or older, with greater than 6.2 kg weight loss in the first 6 months after the procedure, a preoperative serum total bilirubin level greater than 0.5 mg/dL, and in patients who did not receive adjuvant chemotherapy. Conclusions: This study presented risk factors for GB stone formation after gastric cancer surgery, and special attention should be afforded to patients with such risk factors.

This study has been carried out to understand the effect of Gangsim-tang on the hyperglycemic mice induced with Streptozotocin(STZ). The 60 mg/kg of streptozotocin(STZ) was treated into mice twice by 24 hrs interval and then 120 mg/kg STZ was treated again 3 days after the earlier treated. Control group was administered mice with 0.9％ saline(2ml/kg), and experimental groups were administered Gangsim-tang extract(GA group, 10 ㎎/㎏/day; GB group, 30 mg/kg/day) after hyperglycemic induction daily for 6 weeks. The body weight of experimental groups was lower than control. The blood glucose concentration increased continuously, reaching to 298.9 mg/dl after 6 weeks, however, experimental groups of the GA and GB groups significantly(p<0.01) decreased in the 4, 5, and 6 weeks groups. Blood glucose tolerance test was not significant between control and experimental groups. We examined the blood transaminase activities to know the effect of herbal medicine on liver function. The glutamic-oxaloacetic transaminase(GOT) activity was lower in group GB than in control. The glutamic-pyruvic transaminse(GPT) activity was lower in group GA and GB than in control. The superoxide dismutase(SOD) and catalase activities were higher in the group GA compared to control. The results of immunohistochemical study, Langerhan's islet of pancreas was destructed by treatment of STZ in the control, and a few of insulin positive cells observed in the control and experimental group. These results suggest that administration of Gangsim-tang extract to the hyperglycemic mice induced with STZ not regeneration of ${\beta}-cells$ but control of the blood glucose level.

BACKGROUND/OBJECTIVES Oxidative stress is a major cause of cancer. This study investigated the effects of the ethanol extracts from germinated and non-germinated Keunnunjami rice, a blackish-purple pigmented cultivar with giant embryo, on selected human cancer cell lines and on the antioxidant defense system of mice fed with a high-fat diet. MATERIALS/METHODS: High fat-fed mice were orally administered with either distilled water (HF) or extracts (0.25%, w/w) from brown (B), germinated brown (GB), Keunnunjami (K), and germinated Keunnunjami (GK) rice. RESULTS: In comparison with the brown rice extract, Keunnunjami extract showed higher anticancer effect against cervical and gastric cell lines but lower anticancer activity on liver and colon cancer cells. Mice from the HF group showed significantly higher lipid peroxidation and lower antioxidant enzyme activities than the control group. However, the oxidative stress induced by high-fat diet markedly decreased in B, GB, K, and GK groups as compared with the HF group. CONCLUSIONS: Germination may be an effective method for improving the anticancer and antioxidative properties of Keunnunjami rice and extracts from germinated Keunnunjami rice may serve as a therapeutic agent against cervical and gastric cancers and oxidative damage.

The impact of a considerable increase in traffic volume on the emission and concentrations of air pollutants was investigated at three beaches (Haeundae (HB), Gwanganri (GB), and Songjeong (SB)) in Busan during beach opening period (BOP) in 2011. During the BOP, passenger car was the major vehicle type, followed by taxi, and van. CO was the major contributor of total air pollutant emissions followed by NOx, VOC, and $PM_{10}$. For the temporal variation of the emission of air pollutants during the BOP, it was generally the highest in the afternoon followed by the evening and morning, except for SB. For the spatial variation of their emission, it was the highest at GB followed by SB and HB. The emissions of air pollutants during the BOP were generally higher than those during the Non-BOP, except for HB. In contrast, the significant impact of the traffic volume increase on the concentrations of air pollutants at monitoring sites near the three beaches during the BOP were not found compared to the Non-BOP due to the significant distances between monitoring sites of air pollutants and monitoring sites of traffic volume at the beaches.

목적 : 신경병증성 통증 쥐 모델에서 통증 행동과 척수 교세포의 활성화에 대한 반복적 전침의 영향을 실험하였다. 방법 : 21마리 Sprague-Dawley 성체 수컷 쥐를 무작위적으로 대조군, SP6 군, ST36+GB34 군으로 나누었다. 신경병증성 통증은 L5 척수신경을 단단하게 묶는 것으로 유도하였다. 신경병증성 통증이 유도된 뒷발에 기계적 및 열적 민감도를 조사하였다. 모든 군의 L5/6 척수에서 면역조직화학염색법을 수행하였다. 수술 이후 5일째부터 하루에 한번씩 전침을 시행하였다. 결과 : 족삼리(ST36)와 양릉천(GB34)에 적용된 전침은 3번의 처치 이후 실험기간 내내 기계적 및 열적 민감도를 모두 감소시켰다. 삼음교(SP6) 군에서는 진통 효과가 7번의 처치 이후 감소됨을 보였다. 면역조직화학염색법은 ST36+GB34 군에서 L5/6 척수 후각에서 교세포와 성상세포의 활성화가 억제됨을 보였다. 결론 : 이 결과는 반복적인 전침은 신경병증성 통증에 강한 진통 효과를 발휘 하는 것을 시사한다. 신경병증성 통증에서 이 진통 효과는 교세포와 성상세포의 활성화를 억제하는 것과 관련이 있다.

Objectives This study aims to report inflammatory reactions of Pharmacopuncture lubricants (CF and JsD) when administered on GB21, GB20, and TE23 in clinical trials. Methods Follow-up studies were made on each patient's clinical observation and specific managemen. Results 1. Inflammation induced by pharmacopuncture lubricants were limited to local area of administration. 2. Intensity of inflammation was depended on the patient's condition. 3. Inflammation caused pain, skin flare, and discomfort on the patient. Inflammation subsided when dissipating technique was rendered with the conventional acupuncture needle. Conclusions It appears that prolonged usage of pharmacopuncture lubricant on the specific point can induce inflammation, thus using alternative pharmacopuncture is recommended.

Acupuncture is so effective and simple to use in the pain and dysfunction syndrome of TMD. Acupuncture treatment is a point-specific. So, the selection of acupuncture point is very important. According to the traditional meridian theory, we select the points; local points around TMJ and mastication muscles(ST6, ST7, GB20, GB21) and remote point(LI4). And if there is another pain, one or two other points are added. Both neural and humoral mechanism play an important role in acupuncture analgesia. The discovery of spinal gate mechanisms shows somatic stimulation can induce pain inhibition. Humoral mechanism has been established from the discovery of opioid receptors and endogenous opioids. Acupuncture induces a relaxation in the patient, which further decreases the muscle tension.

The wide-band spiral inductor to be monolithically integrated on the AlN substrate as a choking inductor for a compact 10 Gb/s optical transmitter applications is investigated. In order to reduce the parasitic capacitance limiting the choking bandwidth, the AlN substrate is partially etched away, which is analyzed by using an equivalent circuit model. The measured $S_{21}$ transmission response of the fabricated inductor is suppressed as low as -10 dB in the frequency range of 5 to 16 GHz.

본 실험은 사료 내에 인삼 재배 부산물인 진생베리, 인삼잎·줄기를 첨가하였을 때 육계의 생산성, 장기 발달 및 혈액 생화학적 특성에 미치는 영향을 규명하기 위해 수행되었다. 총 120수의 수컷 육계(Ross 308) 초생추를 5처리 4반복으로 배치하여 35일간 사양실험을 실시하였다. 처리구는 대조구(CON), 진생베리 0.5% 첨가(GB1), 진생베리 1.0% 첨가(GB2), 인삼 잎·줄기 0.5% 첨가(GLS1), 인삼 잎·줄기 1.0% 첨가(GLS2)로 구분하였다. 전기(1~21일령)에는 GB2와 GLS1의 증체량이 820.8 g과 821.7 g으로 759.3 g의 대조구보다 유의적으로 높게 나타났다(P<0.05). 후기(22~35일령)에는 GLS2의 사료섭취량이 다른 처리구보다 높았으나(P<0.05), 전 기간(1~35일령)에 걸쳐 분석하였을 때는 모든 항목에서 처리구간 유의차를 볼 수 없었다. 혈청 생화학 분석에서는 글루코스 항목을 제외한 나머지 항목에서는 유의차가 나타나지 않았다. 글루코스 함량은 대조구와 비교하였을 때 GLS 처리구들에서 유의적으로 낮았으며(P<0.05) GB 처리구에서는 낮은 경향을 보였다. 장기 무게는 간, 심장, 비장, 근위, 췌장, F낭 등에서 처리구간에 유의차가 나타나지 않았다. 결론적으로 사료 내 인삼 부산물의 첨가 급여는 육계의 초기 생산성을 개선시켰으며 혈중 글루코스 수준 감소에 효과를 나타내었다.
