Background : Complicated exudative pleural fluid collections have traditionally been treated by either closed tube thoracostomy drainage or by open surgical drainage. Complete drainage is important in order to control pleural sepsis, restore pulmonary function, and entrapment. Recently intracavitary fibrinolytic therapy has been advocated as a method to facillitate drainage of complicated exudative pleural effusion and to allow enzymatic debridemant of the restrictive fibrinous sheets covering the pleural surface. The purpose of this study is to prospectively evaluate the effects of image-guided catheter drainage with high dose urokinase(UK) instillation in the treatment of complicated pleural effusions. Patients : Twenty complicated pleural effusion patients that poorly respond to image-guided drainage were allocated to receive UK. There were 8 pneumonia and 12 tuberculosis. Methods : Drugs were diluted in 250 mL normal saline and were infused intrapleurally through the chest tube or pig-tail catheter in a daily dose of 250,000 IU of UK. Response was assessed by clinical outcome, fluid drainage, chest radiography, pleural ultrasound and/or computed tomography. Results : The mean UK instillation time was $1.63{\pm}0.10$. The mean volume drained UK instillation was $381.3{\pm}314.4\;mL$, and post-UK was $321.6{\pm}489.5\;mL$. The follow up duration after UK therapy was mean $212.9{\pm}194.5$ days. We had successful results in 19 cases (95.0%). There were 12 pleural thickenings (60.0%), 2 markedly decreased effusions (10.0%) and 5 cases of no thickening or effusion. There was recurrence after treatment in only one patient(5%) with complicated pleural effusiondue to tuberculosis. Conclusions : Image-guided drainage with high dose UK instillation (250,000 U/day) in complicated pleural effusion is a safe and more effective method than closed thoracostomy drainage. And this management, in turn, can obviate surgery in most cases.

Background : It has been reported that the expression of protein which influences on the cell cycle is significantly involved in the development, progress, treatment response, and survival of cancer, and also that the degree of expression of p27 and CDK4 is related to the prognosis. Recent research has revealed that uteroglobin, tumor suppressor gene, is related to cell cycle. This study is focused on the relations between expression of proteins related to cell cycle and clinical index of and survival of NSCLC. Methods : We examined immunohistochemically specimens of 110 surgically resected NSCLCs for expression of p27, CDK, Uteroglobin. Tissue array slide were obtained from 110 surgically resected NSCLCs. Immunohistochemical staining was performed by immuno-peroxidase technique using avidin-biotinylated horseradish peroxidase complex. Results : In 110 patients with resected NSCLCs, the ratio of male to female was 87:13, the median age was $56.43{\pm}9.41$ yrs. The positive staining of p27 was detected in 75% of the cases. A non-statistically significant trend toward increased p27 expression was observed in smoker and squamous cell cancer. The positive staining of CDK4 was detected in 89%, which was the highest expression of protein among 3 types. The survival ratio of CDK4 negative staining group was higher than that of positive staining group, which was significant diffrernce(P<0.05). There was no association between p27 or uteroglobin expression and survival. Conclusion : The expression degree of CDK4 is related to the prognosis. This findings suggests that the measurement of CDK4 may be useful in identifying patient at high risk for disease recurrence and survival.

Background : Interferon-gamma ($IFN-{\gamma}$) is essential in the immune response to mycobacterial infections, and a complete or partial deficiency in the $IFN-{\gamma}$ receptor 1 ($IFN{\gamma}R1$) or the $IFN-{\gamma}$ receptor 2 ($IFN{\gamma}R2$) have been reported to confer susceptibility to a disseminated infection with nontuberculous mycobacteria. However, similar mutations in the $IFN-{\gamma}$ receptor have not been specifically examined in the patients with clinical tuberculosis. Methods : This study searched for mutations in the $IFN-{\gamma}$ receptor gene that resulted in a partial $IFN-{\gamma}$ receptor deficiency in six patients with disseminated tuberculosis. The previously identified $IFN{\gamma}R1$ and $IFN{\gamma}R2$ coding regions were sequenced after amplification. Results : There was no partial $IFN{\gamma}R1$ deficiency including a homozygous recessive missense mutation causing an amino-acid substitution in the extracellular domain of the receptor (I87T) and a hotspot for small deletions (818delT, 818del4, 818insA) found in any of the patients. In addition, a partial $IFN{\gamma}R2$ deficiency of the homozygous missense mutation (R114C) was not found in any of the patients. Conclusion : Genetic defects causing a partial $IFN-{\gamma}$ receptor deficiency were not identified in our patients with disseminated tuberculosis.

Objective: We have studied the effects of acupuncture and low level He-Ne laser therapy(LLLT) at $SI_3$, $BL_{40}$ on the tibial, sural nerve injury due to sports-damage or traffic accident and L5 spinal nerve ligature model like general herniation of nucleus pulposus(HNP) in a rat of neuopathic pain. Methods: A model of neuropathic pain was made by injuring tibial nerve and sural nerve while common peroneal nerve was maintained. Also, it was made by isolating left 5th lumbar spinal nerve. Three weeks after the neuropathic surgery, acupuncture and LLLT was injected at $SI_3$,$BL_{40}$ one time a day for one week. LLLT was divided three groups, that is LLLT-1(5mW), LLLT-2(10mW) and LLLT-3(30mW). After that, we examined the withdrawal response of neuropathic rats' legs by Von frey filament and acetone stimulation. And also we examined c-Fos, Nocieptin and KOR-3 in the midbrain central gray of neuropathic rats. Results: As we have observed the effect of mechanical allodynia, LLLT-3 group were diminished on 4 day, 5 day, 6 day and 7 day in the resection model compared with control model, LLLT-1 group were diminished on 5 day, LLLT-2 group were diminished on 3 day and 6 day, LLLT-3 group were diminished on 3 day, 4 day, 5 day, 6 day and 7 day in connected model compared with control group. As we have observed the effect of cold allodynia, LLLT-3 group were diminished on 7 day in the resection model compared with control model, LLLT-1 group were diminished on 6 day, 7 day, LLLT-3 group were diminished on 7 day in connected model compared with control group. As we have observed the effect of activity of c-Fos in the central gray part, LLLT-3 were diminished in resection model compared with control group, LLLT-1 group were diminished in connected model compared with control group. As we have observed the effect of activity of Nociceptin in the central gray part, resection model were not increased compared with control group, LLLT-1 group and LLLT-3 group were increased in connected model compared with control model. As we have observed the effect of activity of KOR-3 in the central gray part, resection model were not increased compared with control group, LLLT-3 group were increased in connected model compared with control model. Conclusions: We have noticed that LLLT-1 and LLLT-3 group have more controllable effect than acupuncture group. This study can be used in clinical therapy for neuropathic pain. But it is not reliability that Nociceptin and KOR-3 have effectively to control pain. Therefore We have to follow up about that.

Hippophae rhamnoides L. (sea buckthorn) is a shrub wood that belongs to the bamboo tree family, and is rich in vitamin C, D, and E; it is referred to as a vitamin tree. It is mainly grown in the high mountains of Europe and Central Asia, and has been widely used in China and Russia as natural medicine. Recent studies have shown that it is effective in the treatment of cancer, liver diseases, cardiovascular diseases, and gastrointestinal diseases. However, results of studies on its effect on the regulation of pain are insufficient. In this study, we investigated the effect of sea buckthorn on the development and control of pain in two facial areas. The experimental animals included 7- to 8-week-old Sprague-Dawley rats (240~260 g). Formalin (5%), which is known as an inflammation inducer, was injected into the vibrissa pad or temporomandibular joints to induce orofacial acute pain. Rubbing or scraping of the region injected with formalin was regarded as a pain index, and the behavioral response was observed for 45 minutes after the injection. Sea buckthorn extract diluted to 150, 300 mg/kg (in 1 ml of distilled water) was orally administered 30 minutes prior to the acute pain. The facial pain behavior was effectively reduced in the 300 mg/kg group when compared to the control group (vehicle). Likewise, in an experiment in which formalin was injected into the temporomandibular joints, effective pain alleviation was confirmed at the same drug concentration. These results suggest that sea buckthorn extract may be useful in the development of therapeutic agents for acute inflammatory pain in the orofacial area and for controlling temporomandibular joint pain.

Mouse calvarial osteoblast cells were isolated and cultured. To examine whether the cells produce active gelatinases in culture medium or not,the cells were analyzed using by zymograsphic analysis on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). We show that mouse calvarial osteoblasts in culture constitutively synthesize progelatinase- A. Then, mouse osteoblasts, which were stimulated by PTH, $1,25(OH)_2D_3$, mononuclear cell conditioned medium (MCM) and IL-1 as bone resorption agent's, showed increased collagenolysis by producing the active gelatinase. However, treatment of indomethacin and dexamethasone significantly decreased those effects of collagenolysis in mouse osteoblastic cells. On the other hand, IL-1 in stimulating bone resorption was examined using fetal mouse long bone organ culture. IL-1 stimulated bone resorption and produced marked resorption when present simultaneously. Furthermore, when it was examined the effects of indomethacin and dexamethasone on the dose dependent responses of $IL-1{\alpha}$, indomethacin and dexametasone produced a rightward shift in the IL-1 dose response curve. The results of in vitro cytotoxicities showed that Taeyoungjon-Jahage water extracts(T.Y.J-J.H.G extracts) have no any cytotoxicities in concentrations of $1-200\;{\mu}g/ml$ and furthermore there is no any cytotoxicity even in concentration of $300\;{\mu}g/ml$ on mouse calvarial bone cells. T.Y.J.-J.H.G. extracts had protective activity against PTH (2 units/mI), or MCM (5%, v/v), or $rhIL-1{\alpha}$ (1 ng/mI) or $1,25(OH)_2D3$ (10 ng/ml) , $IL-1{\alpha}$ and $IL-1{\beta}-induced$ collagenolysis in the mouse calvarial cells. Pretreatment of the T.Y.J.-J.H.G.extracts for 1 h, which by itself had little effect on cell survival, did not enhance the collagenolysis, nor significantly reduced the collagenolysis by pretreatment. Furthermore. the medicinal extracts were shown to have the protective effects against collagenolysis induced by $IL-1{\alpha}$ and $IL-1{\beta}$. Pretreatment of the extracts for 1 h significantly reduced the collagenolysis. Interestingly, the T.Y.J.-J.H.G. extracts were shown to have the inhibiting effects against gelatinase enzyme and processing activity induced by the bone resortion agents of PTH, $1,25(OH)_2D_3$, $IL-1{\beta}$ and $IL-1{\alpha}$, with strong protective effect in pretreatment with the extracts. T.Y.J.-J.H.G. extracts were shown to have the inhibiting effects against $IL-1{\alpha}-$ and $IL-1{\beta}-stimulated$ bone resorption and the effect of the pretreatment with a various concentrations of the medicinal extracts were significant. The inhibition extent and phenomena of IL-1 stimulated bone resorption by nonsteroidal anti-inflammatory agents of indomethacin and dexamethasone were similar to those obtained by T.Y.J.-J.H.G. extracts treatment in the mouse calvarial tissue culture system. These results indicated that the T.Y.J.-J.H.G.-water extracts are highly stable and applicable to clinical uses in osteoporosis.

This study was conducted to evaluate the clinical relevance and effectiveness of ovariectomy (OVE) and ovariohysterectomy (OVH) in terms of postoperative pain behavior and surgical stress. Thirteen healthy intact mongrel purpose-bred female dogs were used in this study. OVE was performed in six dogs whereas OVH was performed in seven dogs. Prior to, 1, 2, 4, 6, 12, and 24 h after surgery, pain assessment was performed by using the Short form of Composite Measure Pain Scale (CMPS-SF) and blood analysis for the determination of glucose, creatine kinase (CK), and cortisol were done. Also, surgical time, duration of anesthesia, and incision length were compared between two groups. As a result, OVH group as opposed to OVE group showed significantly longer in surgical time, duration of anesthesia, and incision length. Also, based on the two-way ANOVA test, the CMPS-SF had significant differences (p < 0.05) between two groups, with the OVE dogs having lower values at 1, 2, 4, and 6 h postoperatively. In addition, in terms of CK, the value at 1, 2, 4, 6, and 12 h were significantly (p < 0.05) increased from the baseline value for the OVH group. However, as for CK in OVE group, the values at 4, 6, and 12 h were significantly increased from the baseline value. As for blood glucose, a significant (p < 0.05) increase from the baseline was shown at 1 h postoperatively in OVH group and no significant increase was shown in OVE group. In terms of serum cortisol level, the values at the 1 and 2 h were significantly (p < 0.05) increased from the baseline value for both groups. In conclusion, our study has shown that OVE can be considered as a superior choice in terms of sterilization technique in female dogs, considering shorter incision length, surgical time, duration of anesthesia along with lower pain and surgical stress response than OVH.

Purpose :We conducted a prospective non-randomized clinical study to evaluate the efficacy and toxic of the preoperative concurrent chemoradiotherapy for locally advanced unresectable rectal cancer. Materials and Methods: Between January 1995 and June 1998, 37 conecutive patients with locally unresectable advanced rectal cancer were entered into the study. With 3- or 4- fields technique, a total of 45 Gy radiation was delivered on whole pelvis, followed by 5.4 Gy boost to the primary tumor in some cases. Chemotherapy was done at the first and fifth week of radiation with bolus i.v. 5-Fluorouracil (FU) 370$\~$450 mg/m$^{2}$, days 1$\~$5, plus Leucovorin 20 mg/m$^{2}$, days 1$\~$5. OF 37 patients, 6 patients did not receive all planned treatment course (refusal in 4, disease progression in 1, metastasis to lung in 1). Surgical resection was undergone 4$\~$6 weeks after preoperative concurrent chemoradiotherapy. Results :Complete resection rate with negative margins was 94$\%$ (29/31). Complete response was seen in 7 patients (23$\%$) clinically and 2 patients (6$\%$) pathologically. Down staging of tumor occured in 21 patients (68$\%$). Treatment related toxicity was minimal except grade III & IV leukopenia in 2 patients, respectively. Conclusion : Preoperative concurrent chemoradiotherapy in locally advanced rectal cancer was effective in inducing down staging and complete resection rate. Treatment related toxicity was minimal. Further follow up is on-going to determine long term survival following this treatment.

Objectives: To investigate the experience and competence of physicians providing emergency medical services at public health sub-centers on remote Korean islands. Methods: This study enrolled 79 doctors who work at public health sub-centers on remote Korean islands. Data were collected in December 2009 via self-administered e-mail questionnaires. The response rate was 44.3%. Results: Emergent situations occurred at most (58.68%) of the public health sub-centers that were surveyed in December 2009. An average of 1.92 cases required treatment by public health physicians. Only 20.25% of the physicians were specialists in emergency medicine, while the remainder were general practitioners (GPs) without clinical experience as emergency doctors. We also found that the physicians we surveyed had insufficient knowledge of emergency medical care. At some health centers only one doctor was available, and there was no medical team in holiday, although most of the physicians indicated that the ideal number of doctors per center was two or three. In cases of emergency, patients were often sent to the mainland by ship without receiving first-aid treatment. The public health sub-centers lacked the necessary medical equipment to save lives in emergencies and lacked escort systems for emergency patients. Conclusions: The Korean government should address the importance of providing emergency care in remote areas. Health administrators should provide suitable manpower, medical equipment, guidelines for emergency medicine, and education for public health physicians on remote islands.

1. 목적 흡연은 치주질환의 주요한 위험 인자 중의 하나이다. 일반적으로 흡연자는 비흡연자보다 비외과적 및 외과적 치주치료에 대한 반응이 덜 효과적인 것으로 알려져 있다. 이 연구에서는 중등도의 만성 치주염이 존재하는 한국인 흡연자와 비흡연자를 대상으로 하여, 비외과적 치주치료인 치석 제거술과 치근 활택술을 시행한 후 6개윌 동안의 임상적 치유 반응을 비교해 보고자 하였다. 2. 방법 20명의 중등도 만성 치주염 환자(흡연자 10명, 비흡연자 10명)를 대상으로 치주낭 깊이(Probing Pocket Depth, PPD), 치은퇴축(GR), 치주탐침시 출혈유무(BOP), #16, 12, 24, 32, 36, 44의 치태지수(Plaque Index, Silness & $L{\"{o}}e$ 1964)를 임상변수로 측정하였다. 치주낭 깊이 (PD)와 치은퇴축(GR)은 전자 탐침(Florida $Probe^{(R)}$ Co. Gainesville, FL)을 이용하여 각 치아당 6군데를 측정하였다. 임상적 부착 수준(CAL)은 치주낭 깊이(PD)와 치은퇴축(GR)의 합으로 계산하였다. 초진시에 전악 임상 검사를 시행하였고, 초진시의 치주낭 깊이에 따라 조사 대상이 되는 치아 부위를 선정하였다. 치주적으로 건강한 부위 $(PD{\leq}3mm)$를 대조군인 1군으로 하고 치주낭 깊이가 4 mm를 초과하고 5 mm 미만인 부위를 2군, 5 mm 이상의 치주낭 깊이를 가지는 부위를 3군으로 설정하였다. 비외과적 치주치료인 치석 제거술, 치근 활택술과 구강위생 교육을 시행하였고 2개월(T1), 4개윌(T2), 6개윌(T3)에 선정된 해당 치아 부위에 대해 임상 재검사를 시행하였다. 3. 결과 BOP와 Plaque Index는 초진, 2, 4, 6개월에 흡연자와 비흡연자 간에 유의할 만한 차이가 없었으나 전반적으로 감소하는 경향이 나타났다. 대조군인 l군에 서는 흡연자와 비흡연자 간에 모든 시기에서 PD, GR, CAL에 유의할 만한 차이가 없었다. 치주낭 깊이가 4 mm를 초과하고 5 mm 미만인 2군에서는 비흡연자에서 6개월에 유의할 만한 치주낭 깊이 감소가 나타났으며, 4개월과 6개윌에 유의할 만한 부착수준의 증가가 관찰되었다(p<0.05). 치주낭 깊이가 5 mm이상인 3군에서는 비흡연자에서 치주낭 깊이 감소가 일관되게 더 많이 나타났으나 통계학적으로 유의할 만한 차이는 6개월째에서만 관찰되었다. 2군과 유사하게 치주낭 갚이 감소는 흡연자보다 비흡연자에서 0.6 mm 더 크게 나타났다. 부착수준의 획득은 2군에서는 4, 6개월째에, 3군에서는 6개월째에 비흡연자에서 유의하게 더 많이 일어났다. 초진시의 치주낭 깊이와 각 시기별 ${\Delta}PD$ 간의 상관관계에서는 치주낭 갚이가 5mm 이상인 3군에서 비흡연자의 경우 6개월째에 가장 강한 상관성이 나타났다($r_s=0.43$, p<0.05). 흡연자에서는 3군에서 어떠한 유의한 상관관계도 나타나지 않았다. 결론적으로 중등도 만성 치주염 환자를 대상으로 한 6개윌의 단기간 연구에서 비외과적 치주치료 후 흡연자에서 비흡연자보다 치주낭 깊이 감소의 개선과 부착수준의 획득이 더 적게 나타나 임상적 치유반응이 좋지 않음을 확인하였다. 이는 흡연이 숙주의 치유반응 부정적인 영향을 주기 때문으로 생각된다.
