Infrared thermographic imaging visualizes noninvasively various abnormal condition by detecting the skin temperature. As the imaging represents the objective condition by the changes in blood flow under the control of autonomic nervous system, it is used to diagnosis and monitor the lumboscral radiculopathy. And asymmetry is important in the diagnosis of disc herniation. The most common type of disc herniation occurs psoterolaterally. This frequently causes nerve root compression leading to a radiculopathy in the distribution of the involved nerve root, most of which also provoke the asymmetric changes in thermography. Central disc herniation, which accounts for 5% to 35% of disc herniation, is typically associated with low back pain. But radiculopathy is usually abscent unless central disc heriniaton is large enough to cause compression of the cauda equina. To evalute the diagnostic value of the thermographic imaging in the diagnosis of central disc herniation, the imaging of 15 normal subjects and 48 patients with central disc herniation documented by CT scan were analyzed. The patients had either bilateral radiculophathy or no radiculopathy. The imaging of patient group with non rediculopathy did not show any significant thermal difference to control. While bilateral radiculopathy group reveled hypothermic pattern compared twith control. Thermal difference between left and right side did not present any significance in non radiculopathy group but hypothermia in bilateral radiculopathy group. Large herniation group demonstrated hyperthemic pattern while the others showed no significant change. Cranial caudal thermal difference did not show any difference between experiment groups. These results shows that infrared thermographic imaging can be used central disc herniation with bilateral radiculopathy, while it seems to little useful on the diagnosis of non radiculopathic disc herniation.

The present study was designed to investigate the effect of different stimulation-duration of high frequency electroacupuncturet(EA) treatment on the neuronal activities in the spinal cord and brainstem using Fos immunohistochemical technique. Three different stimulus-duration was used in this experiment : 30minutes, 1 hour and 2 hours. The summerized results were summerized as follow : 1. The number of Fos expression was significantly increased in the spinal cord dorsal horn depending upon the increase of stimulus-duration (P<0.05). Otherwise, there was no significant difference between 30 minutes EA treated group and anesthetic control. 2. High frequency EA biphasic stimulation significantly enhanced the Fos expression in the DR, middle and rostral portion of PAG LD, and caudal PAG LV after 1 hour and 2 hours treatment. The number of Fos immunoreactive neuron in the brainstem was increased accorcting to the length of stimulus-duration. Those results indicate that at least 1 hour EA treatment was necessary to increase the neuronal activities in the spinal cord and brainstem. Those basic data from this study can be applied to establish the effective treatment of EA for pain control in the clinical field.

금호강의 한 지류인 자양천에 서식하고 있는 잔가시고기 Pungitius sinensis kaibarae(Tanaka)의 인판 발생과정을 조사하였다. 인판의 발생 순서는 체장 13mm경에 미병부에서 최초로 나타났으며 체장 16mm경에는 배지느러미가시의 상부에 흉부인판이 나타났다. 그후 이 두 점을 기점으로 하여 앞뒤로 인판이 차례차례 발생하여 체장 20mm경에 서로 연결되어 trachurus형의 배열이 완성되었다. 체장 22mm경에는 인판의 수가 32-33개로서 성체와 거의 같아졌다. 인판의 발달 상태는 어체의 부위에 따라 다르지만 체장 25mm경에는 최전방부를 제외한 대부분의 인판이 후기의 상태로 되었다. 최전방의 인판은 성체가 되어도 대부분이 중기 상태에 머물러 있었다. 모든 인판은 측선의 neuromast주위에서 발생하였다. 그러나 최전방의 5개까지의 인판위에는 인판이 발생하지 않는 추가적인 neuromast가 있음이 발견되었다. 일본산 잔가시고기와의 관계 및 추가적인 neuromast 발견의 계통분류학적 중요성에 대하여 논의하였다.

2010년 9월 남해 상주 앞바다에서 정치망으로 바다뱀과 엽상자어 4개체(TL 109.8~129.7mm)를 채집하였다. 형태적으로 엽상자어는 8개의 소낭이 항문 앞까지 존재하고, 전체 근절수가 141~151개, 전장에 대한 체고가 10% 이하인 점, 흑색소포가 항문 뒤부터 꼬리지느러미 앞까지 8~9개 분포하는 특징에 따라 까치물뱀속(Ophichthus sp.) 어류와 유사한 것으로 확인되었다. 형태적 결과와는 달리 미토콘드리아 DNA 12S rRNA 826 bp의 염기서열을 분석한 결과, 엽상자어는 돛물뱀속(Pisodonophis sp.) 성어와 100% 일치하였고, 돌기바다뱀(Pisodonophis cancrivorus) 성어와는 98.1% 일치하였다. 본 연구결과에서는 형태 동정결과가 분자 동정결과와 일치하지 않는 결과를 보였고, 이는 까치물뱀속과 돛물뱀속 엽상자어기의 형태적 구분이 매우 어렵다는 것을 의미한다. 본 연구에서는 처음으로 한국에서 채집된 돛물뱀속 엽상자어의 형태적 특징을 상세히 기술하였다.

Purpose: Despite knowledge of the adverse effects of resection-line disease, surgeons continue to perform inadequate resections. This demonstrates the need for a more aggressive approach to assessment of resection margins at operation. Materials and Methods: Seven hundred fifteen gastric cancer patients who were operated on at our hospital from 1992 to 1998 were included in this analysis. Various clinicopathological factors, including resection-line involvement, were ascertained from the surgical and histopathological records. Results: Of the 715 evaluable patients, 27 patients ($3.8\%$) had involvement of one or both resection lines; in 10 patients the proximal resection line only, in 16 the distal resection line only, and 1 both resection lines were involved. Presence of resection-line involvement was significantly associated with T3 and T4 stage, N (+) stage, M (+) stage, type of operation (total gastrectomy), tumor location (entire stomach), size$\geq$11 cm), and gross type of tumor (Borrmann 4 type). When performing a distal subtotal gastrectomy, no involvement was found when the cranial and caudal distances between the lesion and the line of transection was equal to or greater than 2 cm and 3 cm, respectively, for early cancer and 7 cm and 3 cm, respectively, for advanced cancer. When performing a total gastrectomy for upper 1/3 or middle 1/3 gastric cancer, no involvement was found when the cranial distances between the lesion and the line of transection were equal to or greater than 3 cm and 4 cm, respectively, without distinction of the presence of serosal invasion. Conclusions: The difference in survival between positive and negative margin patients is limited to the group of patients with curative surgery. An important principle of treatment is that the entire tumor must be removed with a 3 cm distal margin and a 2- to 7 cm margin depending on the location and the depth of wall invasion of the tumor, to provide histologically negative margins.

Objectives : The present study was conducted to evaluate the analgesic effects of automatically controlled heating acupuncture(ACHA) using 2 different pain models(acute pain and neuropathic pain) and 2 different stimulation conditions (heating $41.5^{\cdot}C$ and heating $44.5^{\cdot}C$) in Sprague-Dawley rats. Methods : Tail flick latency(TFL) to a noxious radiant heat stimulus in lightly anesthetized rats was measured before and after ACHA stimulation for 5-min at the Zusanli(ST36) acupoint. For the neuropathic surgery, the right superior caudal trunk was resected at the level between S1 and S2 spinal nerves innervating the tail. Two weeks after the nerve injury, ACHA stimulation($41.5^{\cdot}C$ or $44.5^{\cdot}C$) was delivered to Zusanli(ST36) for 5 min. The behavioral signs of warm allodynia were evaluated by the tail immersion test (i.e. immersing the tail in warm $water(40^{\cdot}C)$ and measuring the latency to an abrupt tail movement) before and after the ACHA stimulation. Results : In the TFL test, ACHA stimulations under both the conditions above produced more potent analgesic effects than plain acupuncture(PA, acupuncture needle insertion only) and control(no treatment). In the tail immersion test, ACHA stimulations under all of the conditions had markedly relieved the warm allodynia signs. Conclusion : Automatically controlled heating acupul1cture produced analgesic effecs in acute and neuropathic pains.

Objective: To identify the available evidence on the effects of rapid maxillary expansion (RME) with three-dimensional imaging and provide meta-analytic data from studies assessing the outcomes using computed tomography. Methods: Eleven electronic databases were searched, and prospective case series were selected. Two authors screened all titles and abstracts and assessed full texts of the remaining articles. Seventeen case series were included in the quantitative synthesis. Seven outcomes were investigated: nasal cavity width, maxillary basal bone width, alveolar buccal crest width, alveolar palatal crest width, inter-molar crown width, inter-molar root apex width, and buccopalatal molar inclination. The outcomes were investigated at two-time points: post-expansion (2-6 weeks) and post-retention (4-8 months). Mean differences and 95% confidence intervals were used to summarize and combine the data. Results: All the investigated outcomes showed significant differences post-expansion (maxillary basal bone width, +2.46 mm; nasal cavity width, +1.95 mm; alveolar buccal crest width, +3.90 mm; alveolar palatal crest width, +3.09 mm; intermolar crown width, +5.69 mm; inter-molar root apex width, +2.85 mm; and dental tipping, +3.75°) and post-retention (maxillary basal bone width, +2.21 mm; nasal cavity width, +1.55 mm; alveolar buccal crest width, +3.57 mm; alveolar palatal crest width, +3.32 mm; inter-molar crown width, +5.43 mm; inter-molar root apex width, +4.75 mm; and dental tipping, 2.22°) compared to pre-expansion. Conclusions: After RME, skeletal expansion of the nasomaxillary complex was greater in most caudal structures. Maxillary basal bone showed 10% post-retention relapse. During retention period, uprighting of maxillary molars occurred.

Slide tracheoplasty. as a treatment for congenital tracheal stenosis, has been recently reported to have good results and quite a number of advantages as compared with conventional tracheoplasties. The aim of this study is to report a new surgical technique modified from the slide tracheoplasty. "the slide cricotracheoplasty" for the congenital cricotracheal stenosis. A girl was born by Cesarean section and the diagnosis of esophageal atresia (Gross type C) and cricotracheal stenosis (30 % of total length of trachea) was established. Esophageal atresia was successfully corrected at the 8th day of life. At the 31st day of life, corrective surgery for congenital cricotracheal stenosis. the slide cricotracheoplasty. was performed with success. Slide cricotracheoplasty is almost the same procedure as slide tracheoplasty except for two technical features. First the cricoid cartilage was split on its anterior surface. Second the split cricoid cartilage was fixed to pre vertebral fascia to maintain enough space to accommodate the sliding caudal segment of trachea because of the stiffness of the cricoid cartilage. We believe that the sliding cricotracheoplasty is a new surgical technique for congenital cricotracheal stenosis that has similar results and advantages as the sliding tracheoplasty.
