Objective: Bee venom (BV) has been used for the treatment of inflammatory diseases such as rheumatoid arthritis and relief of pain in Oriental medicine. The two main components of BV are melittin and phospholipase A2 (PLA2). Of these, melittin, the major active ingredient of BV, has been reported to induce apoptosis and to possess anti tumor effects. Several studies have established that the agents inducing apoptosis in target organs suppress tumorigenesis. As the other component, PLA2 has been reported to induce neurite outgrowth in PC12 cells. However, there was no report about proliferative effect of BV in neuronal cells. In order to examine the effect of BV on glioma cell, human glioma cell line, U87 was used. Methods: Analysis of proliferation was confirmed by MTT assay. BV increased cell number through dose and duration dependent manner and these effects are apparent at a concentration of 10 ug/ml. To observe which signaling molecules will be activated by BV, phosphorylation of Akt, MAPK, PYK2 or CREB were examined by Western blot analysis. To study the long term effect of BV in U87 cells, the image of cells treated with BV for 4 days were obtained. Results: The phosphorylation levels of PYK2 and Akt were increased at 5 min after addition of 10 ug/ml of BV and sustained to 2 hours. On the other hand, phosphorylation of MAPK and CREB were increased at 5 min, maximum at 10 min, and returned to 30 min. These imply that BV may activate two different signaling pathways, PYK2/Akt and MAPK/CREB. BV treated cells showed increased neurite number and length. Conclusion: These results propose that BV may induce differentiation as well as proliferation of U87 cells through the activation of PYK2/ Akt and MAPK/ CREB.

Bee Venom(below BV) has been used in alternative medicine to treat the diseases, such as pain diseases. BV contains a variety of peptides, including melittin, apamin, adolapin, MCD peptide, enzymes(i.e. PLA2), amines(i.e. histamine and epinephrine), and nonpeptide components. The two main components of BV are melittin and PLA2. The cell cytotoxic effects through the activation of PLA2 by melittin have been suggested to be the critical mechanism for the depress of cancer cell. Melittin and PLA2 have been reported to induce apoptosis and to possess anti-cancer effects and neurite outgrowth in PC12 cells. Analysis of proliferation was confirmed by MTT assay. BV decreased cell number through dose- and duration-dependent manner and these effects are apparent at a concentration of 3 ${\mu}g/ml$. To observe which signaling molecules will be activated by BV, phosphorylation of ERK, p38 MAPK, JNK and ERM were examined by Western blot analysis. To study the long term effect of BV in human gastric adenocarcinoma cell lines, the image of cells treated with BV for 4 days were obtained. BV was shown to exhibit anti-cancer activity in human gastric adenocarcinoma cell lines at a broad range of concentrations of 3 ${\mu}g/ml$. ERK, p38 MAPK and JNK were found to increase in BV treated cells. However, ERM which known to be involved in the cell death, was gradually decreased to 30minutes after addition 3 ${\mu}g/ml$ of BV. These results provide a possible BV-induced inhibitory signal for cancer proliferation that is initiated by the decrease in ERM activity. Moreover, it is likely that the activation of ERK, p38 MAPK and JNK are required for the BV-induced inhibition of cancer proliferation.
Purpose: The management of urethral defect represents one of the most challenging clinical problems in uroplastic surgery. Especially for defect after Fournier's Gangrene, optimal management is still a hard problem. During extensive urethral reconstruction, to overcome the poor vascularity due to periurethral scarred tissue and limitation of the choice of local flap, we report our experience with one-stage reconstruction of urethral defect using a longitudinal tubed flap of scrotal skin. Methods: A 72-year-old man with several years of diabetes mellitus history visited for swelling and pain of scrotal area. After diagnosis of Fournier's Gangrene, radical debridement was performed and 6 cm of urethral defect on border of penile-scrotal ventral area was made. Rectangular scrotal skin flap ($6{\times}2.5\;cm$) based on external spermatic fascia was elevated and tubed longitudinally. After transfer the flap to the defect area, end-to-end anastomosis was performed bilaterally. Results: 4 weeks after the operation, the patient started voiding him-self and urethrography showed good fluence of contrast agent. Long term evaluation reveals stable performance characteristics without any complications. Conclusion: We suggest a one-stage reconstruction of extensive urethral defect using a longitudinal tubed flap of scrotal skin. Advantages of this procedures are simple, one-stage reconstruction with the reliable scrotal skin flap based on external spermatic fascial vasculature, and no donor morbidity.

Primary leiomyosarcomas are rare tumors of the lungs. No typical roentgenographic findings of unusual complex of symptoms distinguish this tumor. The most common therapy is surgical resection. Prognosis and significant survivorship are related to the size, grade, metastasis of the lesion. A 25-year-old female patient with chest pain and cough was admitted. In chest X-ray and CT scan, there was a pulmonary nodule in left upper lung field, She was taken a percutaneous needle aspiration biopsy. The result was a spindle cell tumor. Left upper lobe lobectomy was done, and pathologic diagnosis was a low grade leiomyosarcoma arising from left bronchus. During 5 years of follow-up period, she has not shown any metastasis or local recurrence.
Background: To know the clinical aspects of varicose vein and the effectiveness of operative treatment, the patients who had been operated during the five and a half years were reviewed. Material and Method: From September 1993 to February 1999, 227 patients with varicose vein were operated upon. These patients were reviewed with history taking, physical examination, laboratory tests, operation and follow up visits at an out patient department. Result: The ages of the patients were from 20 to 69 years, mean 40.2 years. varicose veins. Occupations of the patients include housewives, store or factory owners, cooks, waiter or waitresses in a restaurant, salary men(women), teachers, hair stylists, professional athletes, in sequence, most of them require standing all day long. The 126 women had experienced child birth, among them 116 patients delivered more than 2 babies. All patients had protruding leg veins as the symptom. Most of them(61%) had pain. Other additional symptoms were heaviness, heatness, tingling, cramp, fatigue, etc. 68.3% of the patients had the symptoms for more than 10 years. Anatomical location of varicose vein was in long saphenous vein in 157 patients, in small saphenous vein in 27, and in other regions(combined or perforating vein) in 43 patients. There was no operative mortality. There were 2 patients who underwent reoperation due to recurrence during this study period. In one patient, it recurred in the distal perforating vein in small saphenous vein. The other patient had recurrence at the saphenofemoral junction in groin. The patients are doing well after the reoperation, but a long term observation is needed. Conclusion: Clinical aspects of varicose vein were reviewed. For the patients with varicose vein who had saphenofemoral regurgitation, operative treatment seemed to bea safe and effective modality of treatment.

Objective : The aim of this study is to assess outcomes during first one year for patients with severe motor weakness caused by lumbar disc herniation that underwent surgical or nonsurgical treatment. Methods : The 46 patients with motor weakness because of lumbar disc herniation who were treated at neurosurgical department and rehabilitation in our hospital from 2006 to 2010, retrospectively. Each group had 26 surgical treatments and 20 conservative treatments. We followed up 1, 3, 6 months and 12 month and monitored a Visual Analogue rating Scale (VAS) of back and leg pain, Oswestry Disability Index (ODI) and degree of motor weakness. We analyzed the differences between surgical and nonsurgical groups using Mann-Whitney U test and repeat measure ANOVA in each follow-up periods. Results : In the recovery of motor weakness, surgical treatment uncovered a rapid functional recovery in the early periods (p=0.003) and no difference between groups at the end of follow-up period was found (p>0.05). In VAS of back and leg, the interaction between time and group was not found (p>0.05) and there was no difference between groups (p>0.05). In ODI, the interaction between time and group was not found (p>0.05) and there was no difference between groups (p>0.05). Conclusion : Surgical treatment for motor weakness caused by herniated intervertebral disc resulted in a rapid recovery in the short-term period, especially 1 month. We think early and proper surgical treatment in a case of motor weakness from disc herniation could be a good way for providing a chance for rapid alleviation.

During the follow-up period after surgery for spinal dysraphism, a certain portion of patients show neurological deterioration and its secondary phenomena, such as motor, sensory or sphincter changes, foot and spinal deformities, pain, and spasticity. These clinical manifestations are caused by tethering effects on the neural structures at the site of previous operation. The widespread recognition of retethering drew the attention of medical professionals of various specialties because of its incidence, which is not low when surveillance is adequate, and its progressive nature. This article reviews the literature on the incidence and timing of deterioration, predisposing factors for retethering, clinical manifestations, diagnosis, surgical treatment and its complications, clinical outcomes, prognostic factors after retethering surgery and preventive measures of retethering. Current practice and opinions of Seoul National University Children's Hospital team were added in some parts. The literature shows a wide range of data regarding the incidence, rate and degree of surgical complications and long-term outcomes. The method of prevention is still one of the main topics of this entity. Although alternatives such as spinal column shortening were introduced, re-untethering by conventional surgical methods remains the current main management tool. Re-untethering surgery is a much more difficult task than primary untethering surgery. Updated publications include strong skepticism on re-untethering surgery in a certain group of patients, though it is from a minority of research groups. For all of the abovementioned reasons, new information and ideas on the early diagnosis, treatment and prevention of retethering are critically necessary in this era.

Purpose: Keloid is a clinical term characterized by elevation and extension of scar tissue beyond wound margin. Currently, there is no known treatment that shows consistent effect in all patients. Postoperative radiation therapy is known to prevent recurrence of keloid. Methods: We reviewed data of patients who had undergone operation or operation followed by radiation therapy at our institute for the last 12 years. Follow up was possible in 39 patients(21 patients treated only by operation and 18 treated by operation and radiation therapy) We then investigated recurrence in both groups by VAS score. By mail, patients were asked to score their current condition on the bar in 4 aspects(itching, pain, mass lesion(by patients and other persons)). Two criteria were used for defining successful treatment. One is the case which total VAS score was 0, and the other is sum of VAS score of mass lesion was 0 to 5. Results: In the former, recurrence rate is 90.5% in operations-only group but 66.7% in operations plus radiation therapy group(p < 0.05). In the latter, recurrence rate is 66.7% in operation-only group but 22.2% in operations plus radiation therapy group(p < 0.05). Conclusion: These results shows postoperative radiation therapy is effective method in keloid treatment.
Primary lung cancer has increased markedly in its incidence and prevalence rate recently in Korea. In frequency, it occupies the second rank cancer preceded by stomach cancer in korean male. From February 1986 to December 1992, we have operated on 55 cases of primary lung cancer in Korea Veterans Hospital and followed them. The results are as follows; 1. The peak incidence of age of primary lung cancer was 6th decade and 5th decade and those were 87.3% of study group, mainly in male. 2. Symptoms were cough [63.6%], dyspnea [41.8%], chest pain and discomfort [38.2%], blood tinged sputum and hemoptysis [21.8%]. Symptoms were frequently encountered before hospitalization and asymptomatic cases were 9.1% of study group. 3. Methods of diagnostic confirmation were bronchoscopic biopsy [52.7%], percutaneous needle aspiration[PCNA][21.8%], sputum cytolgy [12.7%], open biopsy [12.7%]. 4. Histopathologically, squamous cell carcinoma [76.4%] was the most frequent cancer and adenocarcinoma [10.9%], giant cell cancer [7.3%], and the others in order. 5. Methods of operation were pneumonectomy [32.7%], bilobectomy [18.2%], lobectomy [27.3%], lobectomy and segmenectomy [1.8%], exploration [20%], and overall resectability was 80%. 6. Operative mortality was 5.5% [3 cases] and there were 5 cases of complication. 7. Postoperative long-term follow up reveals that the cumulative survival rates in 6 months, 12 months, 26 months, 34 months, 43 months, 64 months were 89.5%, 71.7%, 66.7%, 57.2%, 50.8%, 42.3% respecively.
Objectives: To observe the mitigating effects of a Traditional Korean Medicine(TKM) treatment program especially including pharmacopuncture, with Cyclophosphamide and doxorubicin chemotherapy on a both sides breast cancer patient. Methods: AA 74 year-old female patient diagnosed with both sides breast cancer (Right) pT1bpN0M0, (Left) pT1cpN1Mx was admitted to hospital of Dong-eui university in May of 2017. She received Cyclophosphamide and Doxorubicin from May $31^{st}$ to August $2^{nd}$, 2017 followed by TKM treatment consisting of herbal medicine, acupuncture, moxibustion and pharmacopuncture (Trionycis Carapax, Non-toxic Bee Venom, and Cultivated Wild Ginseng Extract) for a period of almost 4 months, from May $13^{th}$ to August $19^{th}$, 2017. Symptoms were evaluated by the grade of chief complaints refer to Common Terminology Criteria for Adverse Events (CTCAE) and Eastern Cooperative Oncology Group (ECOG). Results: TKM including pharmacopuncture alleviated chemotherapy-induced nausea, fatigue, joint pain, diarrhea, insomnia. Conclusions: This case study potentiates TKM with pharmacopuncture's significant efficacy in aiding breast cancer patients suffering from Cyclophosphamide plus Doxorubicin induced adverse effects. Further research should take place for clear understanding of the exact amount of dosage and safety. Moreover it must be accompanied by long-term follow up researches.
