Objectives: The purpose of this study was to investigate the treatment methods of chronic pelvic pain, which have no definite treatment methods, and to provide basic data on clinical trials and clinical practical guideline in Korean Medicine related to chronic pelvic pain. Methods: The key words such as 'pelvic pain', 'pelycalgia' are used for the research through 'OASIS, KTKP, RISS, DBpia, KISS'. Total 6 studies were analyzed. Results: 6 studies were chronic pelvic pain case reports. Case reports 6 studies covered a total of 11 cases. Of these, 4 cases related to adenomyosis, 3 cases of endometriosis, and 2 cases of ovarian cyst. However, there were many cases in which the causative disease was not clear. In addition, the majority of the studies reported on the progress of hospitalization, and all studies used herbal medicine, acupuncture and moxibustion. The duration of treatment ranged from 5 to 30 days for hospitalization and 5 months for outpatient treatment. The most commonly used meridian is Conception Vessel (任脈), and SP6 (三陰交) was the most frequently used acupuncture treatment. The herbal medicine Banchong-san (蟠蔥散) was generally prescribed. Conclusions: The effect on treatment of Korean Medicine for chronic pelvic pain had mostly positive results. However, the number of searched studies, which are insufficient for design or analysis of study, is very limited. We hope that this study will be useful for further clinical studies of chronic pelvic pain.

Background and Objectives: Angiogenesis is the process of new blood vessel development from preexisting vessel. Angiogenenesis has been considered to be essential for the growth and expansion of a solid tumor. Vascular endothelial growth factor (VEGF), known as one of the most important vascular permeability factors, induces proliferation of endothelial cells, stiumulates angiogenesis, and increases vascular permeability. Several recents reports have documented that VEGF overexpression is associated with poor clinical outcomes in many maligmancies. The aims of this study were to determine whether microvessel density and VEGF expression are related to clinicopathologic factors such as age, sex, tumor size, tumor stage, and prognostic factors and to evaluate the relationship between VEGF expression and angiogenesis in benign and malignant thyroid tumors. Materials and Methods: The subjects were 65 patients (27 with papillary carcinoma, 27 with adenomatous hyperplasia, 11 with follicular adenoma) who underwent thyroidectomy from 1995 to 2001. Imuunohistochemistry was used to detect VEGF expression and microvessel density (MVD) in paraffin-embedded thryoid tumor specimens. Results: The intensity of the VEGF expression did not show stastically difference between benign and malignant thyroid tumors. There was no apparent correlation between VEGF expression and age, tumor size, T stage or scores of the AGES, AMES and MACIS systems. The neo-microvessel density was higher in the maligant tumor than the benign tumors. Also, higher neo-microvessel density was associated with metastases of the lymph nodes and scores of the AMES and AGES systems. Conclusion: Our results suggest that neo-microvessel vessel density may be a significant prognostic factor in the thyroid papillary carcinoma. But the VEGF expression does not appear to be an significant independent prognostic factor for thyroid papillary carcinoma.

The previous reports have showed that ginseng saponins, which are the active ingredients of Panax ginseng, cause the relaxation of artery that are contracted due to a various of hormones or potassium ($K^+$). Recently, we also showed that ginsenosides differentially regulate channel activity. The purpose of this study was to examine whether ginseng saponins affect contraction induced by $K^+$, serotonin (5-HT), or acetylcholine (Ach) in porcine coronary vessel. Treatment with concentrations of ginseng saponins caused a relaxation of 25 mM KCl-induced porcine coronary artery contraction. Also, ginseng saponin induced a significant dose-dependent relaxation of $3\;{\mu}M$ 5-HT-induced porcine coronary artery with the endothelium. In the porcine artery with the endothelium, ginseng saponins induced a relaxation by $3\;{\mu}M$ 5-HT in a concentration-dependent pattern. Ginseng saponins induced relaxation of both 25 mM KCl- and $3\;{\mu}M$ 5-HT-induced coronary artery contraction in the absence and presence of the endothelium. In contrast, treatment with $100\;{\mu}g/mL$ ginseng saponin did not induce relaxation in coronary artery contraction induced by Ach ($0.01\;{\mu}M$ to $30\;{\mu}M$) in the presence of the endothelium, but did cause significant relaxation of coronary artery contractions by Ach ($0.01\;{\mu}M$ to $30\;{\mu}M$) in the absence of the endothelium. These findings indicate that ginseng saponin (> $100\;{\mu}g/mL$) significantly inhibits porcine coronary artery contractions caused by $K^+$, 5-HT, and Ach. Therefore, in this study, we demonstrated that ginseng saponin may show beneficial roles on abnormal coronary contraction.

We investigated the genetic associations of ischemic stroke by identifying epistasis of its heterogeneous subtypes such as small vessel occlusion (SVO) and large artery atherosclerosis (LAA). Epistasis was analyzed with 24 genes in 207 controls and 271 patients (SVO = 110, LAA = 95) using multifactor dimensionality reduction and entropy decomposition. The multifactor dimensionality reduction analysis with any of 1- to 4-locus models showed no significant association with LAA (P > 0.05). The analysis of SVO, however, revealed a significant association in the best 3-locus model with P10L of TGF-$\beta{1}$, C1013T of SPP1, and R485K of F5 (testing balanced accuracy = 63.17%, P < 0.05). Subsequent entropy analysis also revealed that such heterogeneity was present and quite a large entropy was estimated among the 3 loci for SVO (5.43%), but only a relatively small entropy was estimated for LAA (1.81%). This suggests that the synergistic epistasis model might contribute specifically to the pathogenetsis of SVO, which implies a different etiopathogenesis of the ischemic stroke subtypes.

Citrus unshiu Marc., a family of Rutaceae, has been used as antitussives, antiemetics, expectorants, spasmolytics, stomachics and digestants in oriental medicine. But there is few reports on the pharmacological effects of Citrus unshiu pericarpium. Present experiment was performed to observe the effects of the water extract of Citrus unshiu on isolated auricle and intestine in rabbits and blood pressure in rats and also to study on the active component on the cardiovascular system by means of thin layer chlomatography and spectrophotometer. 1. The water extract showed positive inotropic and positive chronotropic effect in the concentration of $1{\times}10^{-4}g/ml$, $5{\times}10^{-4}g/ml$, and $1{\times}10^{-3}g/ml$. 2. The motility of isolated rabbit intestine was significantly depressed by the water extract. 3. The blood pressure was markedly increased by the water extract. 4. The blood vessel of rabbit ear was constricted by perfusion of the ether extract. 5. The purified alkaloid of Citri pericarpium by ion exchange resin showed the same Rf value with l-synephrine on thin layer chromatography. 6. The purified alkaloid of Citri pericarpium by thin layer chromatography showed the same absorption curve with l-synephrine in the ultraviolet scanning.

Urticaria is a common disease and a well known reaction pattern of the skin characterized by erythema or wheal and edema, that is result of a local leakage of plasma from minute vessel into the connective tissue of the dermis. The urticaria that lasts for more than six of eight weeks, is categorized as chronic urticaria. In Oriental medicine, urticaria is classified as Yeun-jin(慇疹) and similar to Poong-yeun-jin(風慇疹), Poong-so-yeun-jin(風瘙慇疹), Poong-yum-leu, Poong-dan(風丹) and Poong-jin-geu(風疹塊). We report four improved cases of chronic urticaria that had lasted for more than eight weeks. We regarded their chronic urticaria as wind-heat(風熱) and prescribed Bangpungtongsungsan-gami(防風通聖散加味) and Seunggaltang-gami(升葛湯加味) to these patients. These patients showed improvement of chronic urticaria.

Double outlet right ventricle (DORV) and transposition of the great arteries (TGA) with ventricular septal defect (VSD) and pulmonary stenosis (PS) are complex heart diseases, the treatment of which remains a surgical challenge. The Rastelli procedure is still the most commonly performed treatment. Aortic root translocation including an arterial switch operation is advantageous anatomically since it has a lower possibility of conduit blockage and the left ventricle outflow tract remains straight. This study reports successful aortic root transpositions in two patients, one with DORV with VSD and PS and one with TGA with VSD and PS. Both patients were discharged without postoperative complications.

Percutaneous coronary angioplasty is well established therapeutic modality in the management of coronary artery disease. However, the high restenosis rate of 30 to 50% limits its usefulness. The principal mechanism of restenosis, intimal hyperplasia, is the proliferative response of vessel wall to injury, which consists largely of smooth muscle cells. A large body of animal investigations and a limited number of clinical studies have established the ability of ionizing radiation to reduce neointimal proliferation and restenosis rate significantly. Human studies have been reported that intravascular radiation after first restenosis inhibits a second restenosis. Encouraged by these reports, we are also conducting a double blind, placebo-controlled, randomized trial to evaluate this new therapeutic modality in patients with coronary artery stenosis. The objective of our trial is to determine the safety and efficacy of catheter-based solutional beta emitting radioisotope system in preventing restenosis after angioplasty. This review describes the vascular brachytherapy systems and isotopes that have been utilized in the initial clinical trials performed in this area of post PTCA coronary restenosis. The results of many worldwide ongoing clinical trials will determine whether this new technology will change the future practice of vascular intervention.

During the 35 month period from November 1966 to November 1967 and from June 1971 to March 1973 I had experienced 127 cases of non fatal wounds of chest in Viet-Nam. .Among these 127 cases, 62[45.4%] were gun shot wounds, 49[35.8%] were shrapnel wounds and the other were traffic accident. stab wounds and miscellanous. Approximately 21% of gun shot wound were perforating and 79% were penetrating but all cases of shrapnel wounds were penetrating. Of these 127 cases. 90% evacuated to hospital within 6 hours and average time 2.5 hours. The tranfusion requirement of these cases ranged from zero to 36 pints of whole blood with an average of 2.600cc. Initial intrathoracic findings were hemopneumothorax and hemothorax mostly. and the incidence of open thoracotomy was 9.5%[12cases] and closed thoracotomy was 82.8%[104cases], which were contrast to the reports from Korean conflict. I had experienced 24 cases with complication, such as large hematoma in lung parenchyme[8 cases], atelectasis[4 cases], pyothorax [3 cases], pneumonia [3 cases], fibrothorax [3 cases], pleural effusion [2 cases] and wound infection [2 cases]. Mortality rate for entire group was 4.7% but the cases associated with brain injury was 100%, with spinal cord injury was 50%, with large vessel 50%, and abdominal injury was 33.3%, and nobody died solely of thoracic injury.
