  • Background : Chunghyul-dan is a combinatorial herbal medicine; previous studies reported it had therapeutic effects for microangiopathy, a major part in the progression of small vessel disease, as well as having anti-hypertensive, anti-hyperlipidemic, anti-apoptotic, anti-oxidative, and anti-inflammatory activities. Therefor, we examined the inhibitory effect of Chunghyul-dan on stroke recurrence in patients with small vessel disease. Methods : We prescribed Chunghyul-dan at 600 mg a day to patients with small vessel disease, and monitored stroke recurrence, drug compliances, and adverse effect for 1 year. We then performed follow-up brain MRI to find new vascular lesions after 1 year of Chunghyul-dan medication. For the subjects lost to follow-up, we assessed their prognosis after 1 year by telephone. Results : There were 73 subjects treated with Chunghyul-dan for 1 year; new vascular events were found in 3. Of the 85 subjects lost to follow-up, fifty four could be contacted, and eight of them had stroke recurrence. One year of Chunghyul-dan medication reduced the odds ratio of stroke recurrence by 75% compared to the subjects lost to follow-up and the rate increased to 88%, when adjusted for other relevant risk factors for stroke recurrence. These reductions were much higher than those of aspirin and other kinds of conventional anti-platelets. There was no adverse effect in any of the study subjects. Conclusions : We suggest Chunghyul-dan could be useful for inhibition of stroke recurrence. Further study with a randomized controlled trial is needed to confirm this suggestion.

  • Background: Peripheral nerve injuries are commonly encountered clinical problems and often result in severe functional deficit. Bee venom acupuncture has traditionally been used to treat several inflammatory diseases and chronic pain conditions. Objectives: The aims of this study were to compare the effects of bee venom (general bee venom, BV) and sweet bee venom (allergen-removed bee venom, SBV) acupuncture on the recovery rate of locomotor function, the expression of brain-derived neurotrophic factor (BDNF) in the sciatic nerve, and the expression of c-Fos in the brain following sciatic crushed nerve injury in rats, and to evaluate differences due to administration areas. Method: Walking track analysis, Western blot for BDNF and tyrosine receptor kinase B (TrkB), and immunohistochemistry for c-Fos were performed. In this study, comparative analyses of the effects of BV and SBV acupuncture in relation to administration sites, contralateral side or ipsilateral side, were conducted. Results: In the present result, sciatic function index (SFI) in walking track analysis significantly decreased following sciatic crushed nerve injury. The expressions of BDNF and TrkB in the sciatic nerve increased after induction of sciatic crushed nerve injury. C-Fos expression in the ventrolateral periaqueductal gray (vlPAG) and paraventricular nucleus (PVN) also increased. BV and SBV acupuncture treatment improved the SFI in walking track analysis. Treatment with SBV at 1mg/kg showed more potent enhancing effect on SFI compared to BV. Treatment with 1mg/kg BV or 1mg/kg SBV acupuncture suppressed the BDNF and TrkB expression in the sciatic nerve. BV and SBV acupuncture treatment also suppressed c-Fos expression in the PVN and vlPAG regions. Treatment with SBV at 1mg/kg showed more potent suppressing effect on c-Fos expression compared to BV when injected into the contralateral side of the injured nerve. Generally we could not find significant difference in the effects between contralateral side and ipsilateral side of the injured nerve. Conclusion: We have shown that BV and SBV acupuncture treatment can be used as the effective therapeutic modality to ameliorate the symptoms of sciatic crushed nerve injury.

  • 위암은 한국에서 가장 발생빈도가 높은 암이며 암 사망원인의 2위를 차지하고 있다. 치료법 중에서 수술이 유일하게 완치의 기회를 제공하나, 진행 암에서는 근치적 절제(R0 resection, R0 절제)수술 후에도 약 50%의 환자에서 재발을 보여, 보다 효과적인 치료법의 개발이 필요하다. 선행화학요법은 병소가 급격하게 성장, 팽창하는 것을 막고 내성을 지닌 세포의 출현을 예방하며 그렇게 함으로써 완치의 기회를 늘리고, 암의 국소 조절을 더 잘 함으로서 수술의 범위를 줄여 수술로 인한 부담을 줄이며, 절제 불가능한 암을 절제 가능한 암으로 만드는 것이 목표이다. 따라서 치유절제가 불가능할 것으로 판단되었던 위암의 병기를 낮추어 R0 절제 후 완치율을 높일 것으로 기대되고 있으며 계속되는 연구에서 수술로 인한 이환율과 사망률을 높이지 않는 것으로 나타나고 있다. 선행 화학요법에 사용할 수 있는 항암제는 여러 가지이나 가장 높은 효과를 보이는 항암제가 결정되지 않았고 또 항암제를 투여하는 시기, 선행 화학요법 후에 재발을 방지하기 위한 항암제의 복강 내 투여나 방사선 치료의 병용 등이 복막 전이와 국소재발을 줄이는 데 도움이 되는지 등이 향후 시행될 연구에서 규명되어야 하겠고, 또 적절한 수술방법에 관하여도 합의가 이루어져야 하겠다. 선행 화학요법과 관련된 여러 가지 의문들을 해결하기 위한 노력은 다기관이 참여하는 전향적 무작위 3상 임상연구를 통하여 이루어져야 할 것으로 생각된다.

  • 미다졸람은 소아 환자의 진정시 흔히 사용되는 약물로서 안전성이 뛰어나고 사용이 편리하며 투여 방법이 다양하다. 여러 투여 방법 중, 주로 사용되는 근육내 투여 방법은 동통을 유발하기 때문에 어린이의 치과에 대한 공포를 가중시킬 수 있다. 따라서 근육내 투여의 이런 단점을 완화할 수 있도록 용량에 따른 미다졸람 경구 투여의 진정 효과를 근육내 투여시의 진정 효과와 비교 평가하고자 하였다. 총 12명의 환자를 실험대상으로 하였으며 이중 맹검법에 의해 두 번의 내원중 임의로 한 번은 Midazolam 0.75 mg/kg을 경구 투여하고, 한 번은 미다졸람 0.3mg/kg을 근육내 투여하여 치료하였으며, 치료과정 동안 환자의 생징후(말초 동맥혈 산소 포화도, 심박수)와 행동양상을 Ohio State University Behavior rating scale과 Automated Counting System을 사용하여 평가하였다. 생징후의 경우 양 군 모두 정상범위 내에서 안정된 양상을 보였으며, 임상적으로 바람직한 행동양상(Q:Quiet)의 비율이양 군에서 대부분 높게 나타났으며 양군간에 유의 한 차이를 보이지 않았다(p>0.05). 본 연구에서 미다졸람을 근육내 투여한 군과 경구 투여한 군 모두 진정 효과가 양호한 결과를 보였으며 양군간에 유의한 차이를 보이지 않았다(pgt;0.05).

  • The purpose of this study was to develop a multidisciplinary team approach program for stroke survivors, and to identify its effects on their rehabilitation. The team was composed of 7 members: a rehabilitation nurse, a physician, a physical therapist, an occupational therapist, a therapeutic recreational therapist, a nutritionist, and a researcher. A quasi-experimental study was performed with 36 subjects: 18 in the experimental group and 18 in the control group, using a noneqivalent control group pretest-posttest design. The experimental group participated 4 times in rehabilitation programsfocused on information and emotional support provided by the rehabilation team-and received telephone counseling from the researcher. The control group did not receive any treatment. The selection criteria for the subjects in this study were: (a) patients who were diagnosed as having had an ischemic stroke within the last year, (b) patients free of any communication disorder, (c) and those having a primary caregiver who could assist in filling out the form assessing the level of ADL. The data were collected from patients who had been discharged from a tertiary hospital, between October 1st, 1999 and September 30th, 2000. The data were analysed by $X^2$ test, Fisher's exact test, ANCOVA, Wilcoxon's rank sum test, and Wilcoxon's signed rank test using an SAS program. The results were as follows: 1. In terms of physical variables (blood pressure, grasp power, and ADL) 1) There was a significant difference in blood pressure between the two groups (systolic pressure P= .012, diastolic pressure P= .050). 2) There was also a significant difference in grasp power between the two groups (affected side : P= .012, unaffected side : P= .010). 3) There was no significant change in the level of ADL between the two groups. 2. In terms of psychosocial variables (depression, self-efficacy, self-esteem, and social activities) 1) There were no significant differences between the two groups. However, all four psychosocial variables showed a tendency to improve in the experimental group, while only two variables (depression and self-efficacy) showed a simalar tendency in the control group. 2) The level of social activities in the control group decreased significantly after a month (P= .050). 3. The level of life satisfaction improved in both groups, but no significant difference was found. Stroke has high recurrence rate and requires considerable follow-up care. The program used in this study was developed and designed for stimulting the rehabilitation process of stroke survivors. Through the program period of one month (meetings were held weekly), a positive effect was detected in physical variables, although the psychosocial variables did not improve significantly. In retrospect, a one month period may not be an adequate length of time to improve the psychosocial variables, as the stroke survivors were complicated cases, and most of them were elderly. Further research is therefore recommended by increasing the length of program, so that its effect can be more noticeable.

  • In spite of the ongoing advances, standard therapies for oral cancer still has some limitations in efficacy and in ability to prolong survival rate of advanced disease and result in significant functional defect and severe cosmetic deformity. Currently gene therapy using tumor suppressor gene is considered as a potent candidate for new therapeutic approaches that can improve efficacy and reduce complications. The purpose of this research is to identify the role of adenoviral vector to transfer HCCS-1 tumor suppressor gene in oral cancer cells and to find out whether there is a possibility for it to serve in the field of gene therapy. The human SCC-25 cell line was used for transfection. To determine the efficiency of the adenovirus as a gene delivery vector cell line was transduced with LacZ gene and analysed with X-gal staining. Northern blot was performed to confirm the tranfection with HSCC-1 gene and cell viability was assessed by cell cytotoxicity assay. We had successfully construct the recombinant HSCC-1 adenovirus(Ad5CMV-HCCS-1). DNA extracted from Ad5CMV-HCCS-1 revealed HCCS-1 gene is incorporated. The transduction efficiencies were over than 50% of SCC-25 cells with a MOI of 2 and over 95% with a MOI of 50. Northern blot analysis showed that a single 0.6kb mRNA transcript was expressed in Ad5CMV-HCCS-1 transduced SCC-25 cells. There was no or very low transcription HCCS-1 mRNA in wild and Ad5CMV-LacZ transduced SCC-25 cells. Cells transduced with Ad5CMV-HCCS-1 showed significant growth inhibition. By day 6, Ad5CMV-HCCS-1 treated cell count was decreased to 30% of mock-infected cells, while that of Ad5CMV-LacZ treated cells was 90% of mock-infected cells (p<0.05). Finally, these result suggest that the Ad5CMV-HCCS-1 has potential as a gene therapy tool for oral cancer.

  • 암은 한국인의 사망원인 중 1위이며, 간암은 위암, 폐암과 함께 한국인의 3대 암의 하나로 발생 빈도가 높은 암이나, 대부분의 환자가 자각증상이 없어 수술이 가능한 시기를 지난 후에 진단되어 다양한 치료에도 불구하고 생존율이 낮다. 간암은 진단 시 종양의 크기가 비교적 크며, 주위 정상 간 조직의 견딤선량이 낮아 통상적인 방사선치료로는 간암세포의 치사량을 조사할 수 없어 표적장기에는 다량의 방사선을 조사하면서 주위정상조직에는 조사량을 최소로 할 수 있는 세기조절 방사선치료의 필요성은 매우 크다. 그러나 간암이나 폐암에서는 호흡이나 심박동, 장의 연동운동 등으로 상, 하, 좌, 우, 전, 후 방향으로 종양이 움직임으로 계획된 치료선량이 정확한 부위에 전달되는지에 대한 QA 기법이 개발되어 있지 않아 세기조절 방사선치료의 이론적인 많은 이점에도 불구하고 실제 임상에서의 치료는 활발하지 못하다. 본 연구에서는 35예의 간암환자를 대상으로 하여 복잡한 술기가 필요하지 않아 환자가 불편하지 않고 환자의 치료시간도 지연시키지 않으면서, 임상적용이 용이한 QA 방법을 고안하여 간암환자의 임상적용가능성을 입증하고자 하였다. 모든 환자에서 호흡으로 인한 종양의 이동폭이 가장 크다고 보고되고 있는 상하의 margin은 횡격막의 상하 이동을 5회 측정하여 평균값으로 정하고, 이 평균값만큼 상하 자동으로 반복 이동하도록 특수 제작한 장치 위에 팬텀을 고정하여 환자에서와 같은 조건으로 방사선을 조사한 후 방사선조사 선량을 TLD와 전리함으로 측정하고 컴퓨터 계산치와도 비교하여 3% 이내의 오차를 확인하였다. 환자의 첫 번째 치료에서 만든 확인 필름과 인체모형 팬텀에서 같은 방법으로 방사선을 조사하여 만든 확인 필름을 필름 스캐너로 선량을 측정한 후 90% 등선량 곡선을 비교하여도 큰 차이를 발견할 수 없어 임상에서 적용 가능한 QA 기법으로 제안하고자 한다.

  • Sudden idiopathic sensorineural hearing loss is a disease that develops within several hours to several days. Its etiology has not yet been verified, but the disturbance of the circulation of blood in the inner ear, inner-ear hydrops, and viral infection are considered possible causes of the disease. This study was conducted to evaluate the effect of Panax ginseng extract, which is known to have a vasodilatory effect, on sudden sensorineural hearing loss. Sixty-nine patients suffering from sudden sensorineural hearing loss were admitted to Korea University Anam Hospital from March to December 2008. They were divided into the experimental (30 ears) and control (39 ears) groups. Ginseng extract (2700 mg/day, 4 weeks) was added to the therapeutic regimen in the experimental group. The effect of ginseng extract therapy was analyzed according to the factors relating to the prognosis. A considerable hearing improvement was documented in both groups (32.2 dB in the experimental group and 25.8 dB in the control group). However, there was little beneficial effect of ginseng extract on additional hearing improvement compared with control. The total recovery rate of the experimental group (80.0%) was better than that of the control group (58.9%), and the experimental group's high-tone hearing gain at 3 kHz (29.7 dB) was better than that of the control group (21.7 dB). The results of the study suggest that the effects of ginseng therapy tend to be superior to those of the conventional therapy, but the difference between the two is not statistically significant. The hearing gains tend to be in the higher frequencies and may be due to the promotion of cellular differentiation from the supporting cells.

  • Odontogenic keratocyst (OKC) is a epithelial developmental cyst which were first described by Phillipsen in 1956. The frequency of OKC has been reported to vary from 3% to 11% of odontogenic cysts. The most characteristic clinical aspect of OKC is the high frequency of recurrence. The mechanism of recurrence is thought to be related to residues of cyst epithelium and an intrinsic growth potential following excision. And since the lining of the OKC is thin and friable, removal of the cyst in one piece may sometimes be difficult. Complete removal of the cyst lining without leaving behind remnants attached to the soft tissue or bone is necessary to avoid recurrence. Therapeutic approaches vary in different studies from marsupialization and enucleation, which may be combined with adjuvant therapy such as cryotherapy or Carnoy's solution, to marginal or radical resection. The recurrent rate varies from approximately 20% to 62%. And OKC in the angle-ramus region of the mandible had a higher tendency to recur, because of the difficulty in accessing and removing OKC from the ramus. By employing a sagittal splitting of the mandible a good surgical access was provided and cyst could be removed completely. We present an illustrative case of a small, lobulated OKC that involved ramus on mandible, and a review of the contemporary literature.
