Shangwan(CV13), Zhongwan(CV12), Xiawan(CV10), Hefu(L14) and Taichong(LR3) which belong to Conception Vessel and stomach meridian are acupuncture points frequently used for healing gastrointestinal desease in oriental medicine. The present study was conducted to see the effects produced by combined acupuncture(A), electro-acupuncture(EA) and moxibustion using five acupoints which belongs to different meridians on serum gastrin level in rats. Electro-acupuncture (2 Hz, intensity; 10 times muscle twitch threshold) was applied for 30 minutes to Hefu(LI4), Taichong(LR3) under halothane anesthesia. Moxibustion ($1.6{\pm}0.3\;mg$, 5 times of a day) was applied during 3 days to CV10, CV12, CV13 under halothane anesthesia. Combined stimuli of acupuncture at Hefu(LI4), Taichong(LR3) and moxibustion at CV13, CV12 increased serum gastrin level significantly eventough combined simulus of moxibustion on CV 10 was not shown any change. And combined stimul of EA and moxibustion at experimental all groups were not shown any effects. These data suggest that effects of acupuncture and moxibustion are depentent with used acupoints and combination stimuli method.

Objectives : This study was carried out to investigate the anti-toxicity effect of Hwangryunhaedoktang on the dried Mylabris phalerata extract containing cantharidin in ICR mouse. Methods : Dried Mylabris phalerata extracts were orally administered at dosage level 2000, 1000, 500, 250 and 125mg/kg, respectively with and/or without administration of Hwangryunhaedoktang 200mg/kg. During 2 weeks, the changes of body weight, mortality, $LD_{50}$, macroscopic changes of gastrointestinal tract and liver, changes of serum gastrin and somatostatin levels were observed. Results : Decrease of body weight gains was observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Increase of mortality rates was observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. The $LD_{50}$ of dried Mylabris phalerata extract in male mice significantly increased in a case of concomitant used of Hwangryunhaedoktang 268.86 vs 662.05mg/kg. Clinical signs were observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging after dosaging. Increase of number of hemorrhagic and/or erythematous spots in the gastrointestinal tracts, enlargement and congestion in the liver were observed in dried Mylabris phalerata extract-dosing groups, but it was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Increase of serum gastrin level was observed in dried Mylarbis phalerata extract-dosing groups, these state of abnormal increase was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Decrease of serum somatostatin level was observed in dried Mylabris phalerata extract-dosing groups, these state of abnormal decrease was significantly developed in Hwangryunhaedoktang extract-dosing groups after dosaging. Conclusions : We could conclude that the Hwangryunhaedoktang has anti-toxicity effect on the dried Mylabris phalerata extract containing cantharidin.

It is well known that both of acupuncture and moxibustion are effective for treatment of human disease. For years, they have been utilizing a electro-acupuncture (EA) and moxibustion in attempt to manage gastric symptom. However, the data of combined EA and moxibustion on clinical effectiveness is conflicting and the action of combineAd acupoints is not well known. BL21 and ST36 which belong to bladder Meridian and stomach meridian are acupuncture points frequently used for healing gastrointestinal disease in oriental medicine. The present study was conducted to see the effects produced by combined electro-acupuncture(EA) and moxibustion using BL21 and ST36 on serum gastrin level in rats. In experiment, male Spraque-Dawley rats(body wt 140-160g) were selected. EA (2 Hz, intensity ; 10 times muscle twitch threshold) was applied for 30 minutes to ST36 under halothane anesthesia. Moxibustion($1.6{\pm}0.3 mg$, 5 times of a day) was applied during 3 days to BL21 under halothane anesthesia. Synergy effects of combined EA and moxibustion might be in according to stimulated method and used acupoints. The change of serum gastrin levels produced by combined EA and moxibustion is shown after vagotomy. These data suggested that many factors, such as the selection of acupoints, the stimulated EA methods, are capable of affecting combined EA and moxibustion effects and those effects may be not related with nervous system.

Moxa-combustion therapy make use of heat stimulus and chemicals result form when cauterize the skin with moxa cones to medical cares. However, recently moxibustion have been utilized less than acupuncture for treatment of disease in a practicing oriental physicians. To determine variable parameters (the numbers, the times, the quantities, the locations) affected moxibustion's effects, the gastrin serum level in rats were observed. In experiment, male Spraque-Dawley rats (body wt. 140-160g) were selected. Anything is performed to normal group. Control group were only anesthetized with inhalation in normal group. Experimental group were anesthetized and cauterized with moxa at BL21 by way of direct moxibustion. The size of moxa cone is 1.6±0.2㎎. The moxibustion as 5 times a day for five days has shown most significant effects and the moxibustion as a aquantity of 1, 5, 10 times moxa united one respectly, inverse to quantity in effects. The moxibustion for five days has also shown an most significant effects. The moxibustion at unilateral acupoints BL21 have less effects than bilateral one and these effects had no difference between control group after vagotomy. This results indicate that moxibustion's effects are not direct proportion to moxa cone size and frequency but imply that there is adequate value of moxibustion.

The incidence of gastric neuroendocrine tumors (NET) has been increased with the improvement of endoscopy accessibility. The World Health Organization classified NET of low (G1), intermediate (G2), high (G3) grade and neuroendocrine carcinoma with poor differentiation by mitotic count and Ki-67 labeling index. Gastric NET are divided into three subtypes based on the pathophysiology, and treatment is determined according to the subtype and prognostic factors of tumor. For diagnosis, endoscopy with biopsy, endoscopic ultrasonography, abdominal pelvis computed tomography, and serum gastrin level measure are required. In general, type 3, size > 2 cm, deep submucosal infiltration, high histological grade, lymphovascular invasion and metastasis are poor prognostic factors. Type 1 or 2 without these factors are treated by endoscopic resection, and other tumors needs surgery. Endoscopic resection of early type 3 or type 1 and 2 tumors with poor prognostic factors still remains a challenge.

위암 발생률이 높은 우리나라에서는 위암이 발생할 가능성이 높은 고위험군에서 위암 발생 여부를 알 수 있는 생물학적 인자(biological marker)의 개발이 매우 중요한데 가장 많이 연구되는 인자로 혈청 펩시노겐(Pepsinogen)이 있다. 이에 소화기질환을 가지고 있는 환자군과 건강검진센터 수진자를 대상으로 한두 가지 연구에서 혈청 펩시노겐 검사에 영향을 주는 인자를 알아보고 위축성 위염이나 위암 진단에 있어 혈청 펩시노겐 검사의 역할을 알아보았다. 혈청 펩시노겐 검사에 영향을 주는 인자로는 H. pylori 감염이 가장 컸고, 다음으로 성별, 연령이 있었다. 이를 고려한 결과 한국인에서의 내시경적 위축성 위염 진단에 있어서 PG I/II ratio 기준은 H. pylori 감염 여부에 따라 달랐는데 H. pylori 감염이 없는 경우는 PG I/II ratio 6이, H. pylori 감염이 있는 경우는 국제적 기준인 PG I/II ratio 3이 예민도와 민감도에서 우수했다. 또한 한국인에서의 위암이나 위축성 위염 진단에 있어 PG I이나 PG II는 별로 유용하지 않은 반면 PG I/II ratio는 비교적 유용함을 알 수 있었고, 특히 H. pylori 감염이 있는 경우 PG I/II ratio $\leq3$ 이하가 위암 발생위험도 예측에 도움이 되었다. 결과적으로 혈청 펩시노겐을 위암이나 위축성 위염 진단 biomarker로 사용할 때는 기존의 국제적인 기준도 중요하지만 각 나라의 현실에 맞는 기준치 적용을 위해 validation study를 시행하고 사용하는 것이 바람직한 것으로 보인다.

Background: The aim of this study was to investigate clinicopathologic features of type 3 gastric neuroendocrine neoplasm (NEN) by treatment modality. Methods: The Korean Society of Gastrointestinal Cancer conducted the Korean Gastroenteropancreatic Neuroendocrine Tumor Registry, a retrospective registry database of gastroenteropancreatic neuroendocrine tumors from 16 hospitals in Korea. The normal serum gastrin level range was defined as <100 pg/mL, and gastric NEN patients with normal gastrin level were selected for analysis. Results: Among 358 patients with gastric NEN, 21 (5.9%) patients were classified with type 3 gastric NEN. The median age was 53 years (range 30-74). According to the WHO 2010 classification, 13 (61.9%) patients had grade 1, and 8 (38.1%) patients had grade 2 or 3. Endoscopic treatment was performed in 14 (66.7%) patients, and surgery was performed in 7 (33.3%) patients. The tumor size was smaller in the endoscopic treatment group than in the surgery group (0.6 cm vs 1.3 cm, p=0.006). After treatment, there was one recurrence in the surgery group. Conclusion: In small size Type 3 gastric NEN, endoscopic treatment was associated with a good prognosis, compared to surgery. Thus, endoscopic treatment can be used an alternative modality in selected cases of type 3 gastric NEN.

Objectives : The objective of this study was to compare, the potency of toxicity of Cantharidin containing dried Mylabis phalerata (MP) extract and it's modifier. Methods ： They were monitored at dosage level 2,000, 1,000, 500, 250 and 125 mg/kg, respectively. Changes of body weight, clinical signs, mortality, LD50, macroscopic changes of gastrointestinal tract and liver were observed after single oral dose of test articles with changes of serum Gastrin and Somatostatin levels. Results ： Dosage-dependent decrease of body weight and/or gains were demonstrated in dried MP extract-dosing groups, were also detected in modified and dried MP extract-dosing groups at 2,000 and 1,000 mg/kg-dosing group. However, below 500 mg/kg-dosing group, the body weights were significantly increased compared to that of equal dosage group of dried MP extract-dosing group. Dosage-dependently detected clinical signs in dried MP extract-dosing groups, were also detected in modified and dried MP extract-dosing groups at 2,000 and 1,000 mg/kg-dosing group. However, below 500 mg/kg-dosing group, these clinical signs dramatically were decreased compared to that of equal dosage group of dried MP extract-dosing group. Dosage-dependent increase of mortality rates were observed in dried MP extract-dosing groups, were also detected in modified and dried MP extract-dosing groups at 2,000 and 1,000 mg/kg-dosing group. However, below 500 mg/kg-dosing group, the mortalities were significantly decreased compared to that of equal dosage group of dried MP extract-dosing group. The LD50 of dried MP extract in male mice was dramaticlly increased in their modify, 265.86 vs 426.99 mg/kg. Dosage-dependently increase of number of hemorrhagic and/or erythematous spots detected in the gastrointestinal tracts of dried MP extract-dosing groups, were also detected in modified and dried MP extract-dosing groups at 2,000 and 1,000 mg/kg-dosing group. However, below 500 mg/kg-dosing group, these abnormal spots were dramatically decreased compared to that of equal dosage group of dried MP extract-dosing group. Dosage-dependently increase of degrees of enlargement and congestion detected in the liver of dried MP extract-dosing groups, were also detected in modified and dried MP extract-dosing groups at 2,000 and 1,000 mg/kg-dosing group. However, below 500 mg/kg-dosing group, these abnormal signs were dramatically decreased compared to that of equal dosage group of dried MP extract-dosing group. Dosage-dependently increase of serum gastrin levels of dried MP extract-dosing groups, were also detected in modified and dried MP extract-dosing groups at 2,000 and 1,000 mg/kg-dosing group. However, below 500 mg/kg-dosing group, these abnormal increase were dramatically decreased compared to that of equal dosage group of dried MP extract-dosing group. Dosage-dependently increase of serum somatostatin levels of dried MP extract-dosing groups, were also detected in modified and dried MP extract-dosing groups at 2,000 and 1,000 mg/kg-dosing group. However, below 500 mg/kg-dosing group, these abnormal increase were dramatically decreased compared to that of equal dosage group of dried MP extract-dosing group.

MNNG 투여에 의한 백서 위십이지장암 발생에 있어서 우유의 영향을 조사하고 그 원인을 분석키 위해 조직학적 및 혈청학적 분석을 시도하였다. 실험군은 생후 8주 전후의 Sprague-Dawley 백서 136마리로서 일반사료만 준 대조군 20마리(제 1군)와 6% 우유사료만 준 군 20마리(제 2군), MNNG$(100\;{\mu}g/ml)$ 투여군 24마리(제 3군), MNNG 및 6% 우유사료군 24마리(제 4군), MNNG 및 13% 우유사료군 24마리(제 5군), MNNG 및 26% 우유사료군 24마리(제 6군)로 분류한 후 군별에 따라 28주간 발암제 및 우유사료를 투여하고 실험시작 40주째 생존한 109마리에 대해 다음과 같은 결과를 얻었다. 1. MNNG 단독 투여로 실험시작 12주 이후의 성장에 영향을 주었으나(p<0.01) 가역적이었고 생존에 미치는 영향은 없었다. 2. 위암발생은 대조군, 우유사료군에서 없었고 제 3군 25%, 제 4군 36.8%, 제 5군 27.8%, 제 6군 14.3%로 우유사료군에서 우유농도 증가에 따라 위암발생의 감소가 관찰되었고 제 6군에서는 제 3군보다 암발생이 억제되었다. 그러나 제 4군에서는 제 3군보다 상회하는 발암율을 보였다. 3. 위의 양성병변은 재생성 과증식, 선종성 과증식, 섬유 증식증 등이었고 MNNG 투여 각 우유사료군간의 분포는 우유농도 증가에 따라 위 양성병변이 증가하였으며 특히 암 수반율이 작은 재생성 과증식 발생군에서 뚜렷하였다. 재생성 과증식군에서의 암 수반율은 22.2%, 선종성 과증식군에서는 57.9%로 유의한 차이를 보였다(p<0.05). 4. 소장암 발생은 위암에서와 같이 십이지장의 선암이 주이었고 종양 발생 빈도는 3군에서 5%, 4군에서 21.1%, 5군에서 22.2%, 6군에서 9.5%이었으나 발생예수가 작아 각 군간의 통계적 유의성은 없었다. 5. 혈중가스트린치는 암발생이 많았던 제 4군에서 증가되었고(p<0.01), 양성 위 병변과 관련된 혈중 가스트린치도 제 4군에서 증가하였으며, 특히 재생성 과증식 수반동물군에서의 가스트린 증가는 유의하였으며(p<0.05), 위암발생군에서도 가스트린이 유의한 증가를 보였다(p<0.05). 이상의 성적을 바탕으로 위암발생은 우유농도 증가에 따라 감소되며 고농도의 우유사료군에서 발생이 억제되고 있음은 전암성 병변으로부터의 암발생을 억제하려는 우유의 암 발생 지연효과인 것 같다. 저농도 우유사료군에서의 암발생율의 증가는 혈중 가스트린치의 증가가 그 한 요인으로 해석되며 암발생군에서의 가스트린치의 증가와 더불어(p<0.05) 전암성 병변인 재생성 과증식군에서의 가스트린 증가가(p<0.05) 이를 뒷받침하고 있다.
