Objectives This study was carried out to investigate the experimental effects of Lonicerae Caulis and Bee-venom Acupuncture in Yanglingquan (陽陵泉, GB34) that have clinical efficacy in the Rheumatoid Arthritis. Methods Materials of present study are Lonicerae Caulis Extracts (LCE), Bee-Venom Acupuncture (BVP), Sprague-dawley rats (250 g or so, ♂), and various kinds of needing experimental studies. We measured several experimental items of the rats with the arthritis induced by Freund's complete adjuvant (0.2 ml/kg), such as body weight, rate of paw edema, analgesic effect by hot plate method, WBC, TNF-${\alpha}$ cytokine and IL-10 cytokine. Rats were divided into four groups; Normal group that was treated with normal saline 1.0 ml (o.p) and $15{\mu}l/kg$ (GB34) to normal rats, Control group that was treated with normal saline 1.0 ml (o.p) and $15{\mu}l/kg$ (GB34) to pathologic model rats induced by Freund's complete adjuvant 0.2 ml/kg, Experimental group A that was treated with LCE 1.0 ml (o.p) and normal saline $15{\mu}l/kg$ (GB34) to pathologic model rats induced by Freund's complete adjuvant 0.2 ml/kg and Experimental group B that was treated with LCE 1.0 ml (o.p) and BVP $15{\mu}l/kg$ (GB34) to pathologic model rats induced by Freund's complete adjuvant 0.2 ml/kg, and the experiment took over after 28 days. The results were analysed using SPSS for windows 12.0. Results Experimental group A showed the increase in body weight, paw licking times and IL-10 cytokine compared to Control group. Also it was decreased in rate of paw edema, WBC, and TNF-${\alpha}$ cytokine compared with Control group. Experimental group B showed the increase in body weight, paw licking times, and IL-10 cytokine compared to Control group, and showed the decrease in rate of paw edema, WBC and TNF-${\alpha}$ cytokine compared to Control group. Especially TNF-${\alpha}$ cytokine and rate of paw edema were accepted statistical significance compared with Control group. Conclusions It is suggested that Lonicerae Caulis (o.p) and Bee-venom Acupuncture (GB34) can be used in the treatment of rheumatoid arthritis.

Information on productivity of hospital personnel is required for optimum staffing and hospital management. This study deals with the quantitative aspects of workload of medical personnel in training hospitals by their specific characteristics. Specifically this study attempted to find relevant determinants of the productivity of medical personnel using multiple stepwise regression analysis based on data obtained from 135 training hospitals. The findings of this study were as follows: 1) Daily average number of outpatients and inpatients treated by a physician were 20.4 and 10.2, respectively. 2) Daily average number of patients cared by a nurse was 8.2. Daily average number of tests performed by pathologic technician and radiologic technician were 83.2 and 21.5, respectively. 3) Productivity of medical personnel were significantly different for the three groups of factors: hospital sire (number of beds, number of medical personnel per 100 beds): institutional characteristics (medical school affiliation, training type, profit status); and environmental factors (location, number of physician and beds per 1,000 population in the region). 4) The factors a(footing the productivity varied according to the types of medical profession: the number if beds, the number of physicians per 100 beds, training type, and profit status for physicians; the number of nurses per 100 beds, the number of beds, medical school affiliation for nurses; the number of physicians per 100 beds, the number of technicians per 100 beds, and ownership for pathologic technicians; the number o( technicians, training type, and the number of physicians per 100 beds for radiologic technician.

Objectives: In these days, patients with stage I breast cancer have increased by regular health examination and diagnostic tool development. The aim of this retrospective study is to identify systemic recurrence related factors after breast conserving surgery (BCS) for stage I breast cancer. Methods: In this study, we analyzed the correlation between systemic recurrence and pathologic factors. We reviewed 223 patients who underwent BCS for stage I breast cancer. Postoperative pathologic factors, recurrent rates and sites were studied. In addition, preoperative patients'data were also collected. Statistical analysis was done by using PASW 16.0 (SPSS Inc., Chicago, IL, USA). Results: Systemic recurrence was found in 16 patients (7.17%) within 5 years after primary surgery. 5 patients had lymphatic invasion and 6 patients had vascular invasion. Lymphatic and vascular invasion had statistical correlation with systemic recurrence (P = 0.004, P = 0.001). Conclusions: In this retrospective study, we can conclude that vascular invasion and lymphatic invasion are related systemic recurrence after BCS for stage I patients. Further studies with large cohort will be required to fully understand the risk factors of systemic recurrence for stage I breast cancer patients.

Purpose: The aim of this study was to evaluate the clinical significance of 24 hour pH monitoring in the pediatric patients with recurrent vomiting or regurgitation. Methods: We performed 24 hour pH monitoring on 87 pediatric patients with recurrent vomiting or regurgitation using GastrograpH with glass electrode. The pathologic GER was determined by the reflux index (RI). RIs>10% were considered positive in patients <1 year of age, whereas RIs of >5% were positive in other age groups. We evaluated the mean and standard deviation of the reflux parameters between physiologic and pathologic GER groups, and also compared the reflux indices of each group with respect to time zones of the day. Results: Pathologic GER was found in 32 of 87 patients (36.8%), and the age incidence included 32.5% in infants <6 months old, 13.3% in infants aged 6 months-1 year old, 61.5% in children aged 1~2 years old, 14.3% in children aged 2~3 years old and 66.7% in children >3 years old. In physiologic GER patients, the RI was $3.7{\pm}2.9%$ for the patients <1 year old (group A), and $1.8{\pm}1.5%$ for those ${\geq}1$ year old (group B) which was statistically significant between the 2 age groups (p=0.02). The number of long refluxes more than 5 minutes was significantly increased (p=0.03) in group A ($1.7{\pm}1.9$) than in group B ($0.8{\pm}1.0$). The duration of the longest reflux was significantly longer (p=0.007) in group A ($604{\pm}551$ sec) than in group B ($275{\pm}296$ sec). In pathologic GER patients, the RI was $17.7{\pm}11.6%$ for the patients <1 year old and $7.8{\pm}2.9$ for those ${\geq}1$ year old. The number of long refluxes of more than 5 minutes were $8.9{\pm}4.6$ and $3.2{\pm}1.8$, and the duration of the longest reflux were $1955{\pm}2190$ sec and $1093{\pm}706$ sec for each age group. In both physiologic and pathologic GER patients, there was no significant difference of RI among the time zones of the day. Conclusion: Pathologic GER was found in 36.8% of patients. There was significant difference of RI between those <1 year old and those ${\geq}1$ year old in physiologic GER patients. There was no significant difference of RI among the time zones of the day in both pathologic and physiologic groups. In our study, the frequency of pathplogic GER was too much higher in age group of 1~2 years old (61.5%) than in group of 6 months-1 year old (13.3%), which means that further study is needed to determine the pathologic criteria of RI (Vandenplas criteria is >5%) in the age group of 1~2 years old.

Purpose: To find out the pathologic symptoms, and the incidence and clinical significance of the coexistence of internal derangement of knee(IDOK) in osteochondroma around the knee. Materials and Methods: We retrospectively reviewed forty-five patients under 20 years of age treated with the excision of the osteochondroma around the knee between 1995 and 2004. We analyzed age, gender, past history, family history, solitary or multiple osteochondroma, presenting pathologic symptoms, and causes of IDOK. Results: IDOK was confirmed in nine(20%) among the 45 cases. There were four cases of multiple osteochondromatosis, and IDOK was coexisted in one case among them. The most common presenting pathologic symptoms were painless mass of 38 cases, however 9 cases among them had joint pain for IDOK. There were 7 cases of meniscal tears and 2 of pathologic plica. Discoid meniscus was found in 4 cases among the 7 cases of meniscal tears. Conclusion: Coexistence of osteochondroma around knee and IDOK in this study probably represents a coincidence rather than a real association. However the incidence might be not low, special study and close observation should be done.

Unreduced small bowel intussusception requires operative treatment although the rate of spontaneous reduction is 60 to 70 %. The aim of this study is to compare clinical characteristics and outcome between spontaneous reduction and operation group and to analyze factors related to decisions to treat small bowel intussusceptions. The records of 25 patients with small bowel intussusceptions treated in Seoul National University Children's Hospital from January 1999 to August 2009 were reviewed respectively. Spontaneous reduction group (n=12, 48 %) had signs and symptoms of vomiting, abdominal pain, currant jelly stool, abdominal distension, fever, increased CRP but no rebound tenderness. One of them had been diagnosed with Henoch-Schonlein purpura and no one displayed pathologic leading point by image study. Operation group (n=13, 52 %) consisted of patients who had primary surgery. Their signs and symptoms were similar to spontaneous reduction group. Seven of them had underlying diseases such as Crohn' disease, ALL, Lymphoma, Peutz-Jeghers syndrome (n=3), post-transplanted state of liver and 2 of them displayed Peutz-Jeghers polyp and Meckel's diverticulum as pathologic leading point by preoperative ultrasonography. Mean relieve interval (interval between onset of symptoms and reduction/operation) was 1.78 days in spontaneous reduction group and 2.25 days in operation group (p=0.341). Seven of operation group had manual reduction and 6 out of 7 received segmental resection of the small bowel. No one of them underwent manual reduction and all of them underwent segmental resection were found to have pathologic leading points [Peutz-Jeghers polyp (n=3), Meckel's diverticulum (n=2), lymphoma (n=1)] during operation. In conclusion, 48% of small bowel intussusceptions resolved spontaneously. Patients' symptoms and relieve intervals were not related to the operative decisions. We therefore recommend significant factors for determining treatment plan such as change of clinical symptoms, underlying disease or pathologic leading point by imaging.

Introduction : Korean red ginseng has been shown to have an preventive effect on atheroma formation and enhancing effect on nitric oxide synthesis in endothelial cell inducing vasodilatation. However, there are few studies showing the effect of Korean red ginseng on blood pressure and vascular(endothelial) pathologic changes together. We designed this study to show changes of blood pressure and vascular pathologic findings with Korean red ginseng administration compared with Chinese red ginseng and control for 3 months in rats. Materials and methods : We studied the in vitro hypotensive effect and effect on vascular pathologic changes of Korean red ginseng compared with Chinese red ginseng and control. Rats were randomly assigned to three groups(Korean red ginseng, Chinese red ginseng and control) and evaluated by blood pressure and aortic vascular(endothelial) pathologic changes monthly during 3-month administration. All results were analyzed by paired T-test, ANOVA and post-hoc. Results : Blood pressure lowering effect was noted on Korean red ginseng and Chinese red ginseng compared to control. Especially, in Korean red ginseng group, hypotensive effect was showed in first and second month, but, in Chinese red ginseng group, it was just noted in first month. In case of vascular(aortic endothelial) pathologic finding, endothelial wall thickening and elastic fiber tearing were noted in Chinese red ginseng group compared with Korean red ginseng group and control with statistical significance.(p<0.05) Discussion : These results suggested Korean red ginseng could have more hypotensive effect and maintenance rather than Chinese red ginseng. And the difference of hypotensive effect between Korean red ginseng and Chinese red ginseng might has some association with difference of vascular pathologic findings in each group. However, further evaluation and research of other mechanism will be needed to convince this hypothesis.

Purpose: The objective of this retrospective study was to identify predictive factors for the complete pathologic response and tumor downstaging after preoperative concurrent chemoradiotherapy for locally advanced rectal cancer. Materials and Methods: Between the years 2000 and 2008, 39 patients with newly diagnosed rectal cancer without prior evidence of distant metastasis received preoperative concurrent chemoradiotherapy followed by surgery. The median radiation dose was 50.4 Gy (range, $45{\sim}59.4\;Gy$)). Thirty-eight patients received concurrent infusional 5-fluorouracil and leucovorin, while one patient received oral capecitabine twice daily during radiotherapy. Results: A complete pathologic response (CR) was demonstrated in 12 of 39 patients (31%), while T-downstaging was observed in 24 of 39 patients (63%). N-downstaging was observed in 18 of 28 patients (64%), with a positive node in the CT scan or ultrasound. Two patients with clinical negative nodes were observed in surgical specimens. The results from a univariate analysis indicated that the tumor circumferential extent was less than 50% (p=0.031). Moreover, the length of the tumor was less than 5 cm (p=0.004), while the post-treatment carcinoembryonic antigen (CEA) levels were less than or equal to 3.0 ng/mL (p=0.015) and were significantly associated with high pathologic CR rates. The univariate analysis also indicated that the adenocarcinoma (p=0.045) and radiation dose greater than or equal to 50 Gy (p=0.021) were significantly associated with high T-downstaging, while a radiotherapy duration of less than or equal to 42 days (p=0.018) was significantly associated with N-downstaging. The results from the multivariate analysis indicated that the lesser circumferential extent of the tumor (hazard ratio [HR] 0.150; p=0.028) and shorter tumor length (HR, 0.084; p=0.005) independently predicted a higher pathologic CR. The multivariate analysis also indicated that a higher radiation dose was significantly associated with higher T-downstaging (HR, 0.115; p=0.025), while the shorter duration of radiotherapy was significantly associated with higher N-downstaging (HR, 0.028; p=0.010). Conclusion: The circumferential extent of the tumor and its length was a predictor for the pathologic CR, while radiation dose and duration of radiotherapy were predictors for tumor downstaging. Hence, these factors may be used to predict outcomes for patients and to develop further treatment guidelines for high-risk patients.

Background: Esophageal squamous cell carcinoma (ESCC) is a common cancer in the north east of India. The present study concerned the prevalence of human papilloma virus (HPV) in the ESCC in north eastern India and its impact on response to chemotherapy. Materials and Methods: p16 expression, a surrogate marker for HPV infection was assessed in 101 pre-treatment biopsies of locally advanced ESCC, reported from a comprehensive cancer centre in north east India, using immunohistochemistry. All patients received neo-adjuvant chemotherapy. Response was assessed clinically and histopathologically with attention to p16 expression. Results: p16 was expressed in 22% of ESCC (22 out of 101) and was more prevalent in patients who were more than 45 years of age (P=0.048). p16 positive tumors appeared more commonly in the upper 2/3 of the thoracic esophagus (18 in 22). Nine of the 22 (41%) p16 positive tumors achieved pathologic complete response following neo-adjuvant chemotherapy (P=0.008). There was a trend towards reduced mortality in this group (P=0.048). Some 9 of the 20 (45%) patients who achieved pathologic complete response were p16 positive. Conclusions: Expression of p16 in ESCC correlates with higher rate of pathologic complete remission in patients undergoing neo adjuvant chemotherapy and could be a predictive marker for response assessment.
