안면경련의 치료에 있어 CT 유도화 화학적 안면신경차단
정진우(Jin Ou Jeong),권재영(Jae Young Kwon),김해규 대한통증학회 1993 The Korean Journal of Pain Vol.6 No.2
Hemifacial spasm is a distressing condition characterized by involuntary, intermittent, uni- lateral twitching of all or parts of the muscles innervated by the facial nerve. This occurrence is most common in middle-aged women. Because etiology of idiopathic hemifacial spasm has remained undefined, no causative agent nor reliable treatment has been established. This report describes a case of CT guided chemical facial nerve block for the treatment of hemifacial spasm. An injection of small amount(0.1 ml) of alcohol(95%) provided relief of the facial spasms.

N/A This study examined the microscopic changes following irradiation of infrared low dose laser on injured sciatic nerves of rats. In these days, many clinicians use the low-dose laser therapy in pain clinicians use the low-dose laser therapy in pain clinic on various fields and dieases. But the basic mechanism and indications were not known completely. Low-dose IR(infrared) laser irradiation applied to a crushed injured sciatic nerve of rats in the right leg in bilaterally inflicted crush injury. The results were as follows I) There are a little histological differences between laser treated group and nontreated group. 2) Low power IR-laser irradiation, when applied to the injured sciatic nerve, increased vascu- larization and relatively well conserved tissue organization. 3) There are little histological difference in distal muscle biopsy, but atrophic muscle fibers were seen partially. 4) We found out that more hypertrophic epineurium was present in laser-treated group.

Transurethral resection syndrome (TURS) is one of the complications of endoscopic transurethral operation with irrigation fluid. TURS comprehensively refer to several clinical symptoms and signs caused by intravascular absorbtion of irrigation fluid, hypertension, bradycardia, arrhythmia, respiratory distress, hypotension, confusion, blindness, seizure, coma, hyponatremia, and hypoosmolarity. TURS is mainly known as the complication of the transurethral resection of prostate (TURP), and rarely found in the procedures such as transurethral resection of bladder tumor (TUR-BT), hysteroscopy, cystoscopy, and arthroscopy. Only a few cases of TURS after TUR-BT have been reported. The patients on maintenance hemodialysis were restricted in the amount of water intake for volume control. They were susceptible to the absorption of irrigation fluid during TUR-BT since they had anuria. We hereby report the 2 cases maintenance hemodialysis patients who were led to TURS after TUR-BT.

Backgroud/Aims: The purpose of this study was to examine the clinical observations of patients with hematochezia in attempt to determine the appropriate evaluation and treatment of this group of patients. Methods: Seventy patients with hematochezia were admitted to Intemal medicine (IM) Department of Chungnam National University Hospital from January 1990 to August 1997. The clinical observations of patients with hematochezia were reviewed and the results are as follows. Results: 1) The causes of the hematochezia were ischemic colitis (18.6%), hemorrhoids (15.7%), ulcerative colitis (14.3%), unknown (12.8%), rectal cancer (7.1%), nonspecific ulcers (rectum; 4.3%, colon; 1.4%), diverticulosis (5.7% ), colon cancer (4.3%.), mdiation colitis (2.9%), angiodysplasia (2.9%), polyps (2.9%), Samonella colitis (2.9%), rectal varix (1.4%), ileitis(1.4%) and ileal ulceration (1.4%). 2) The average hemoglobin of the patients with hematochezia was 9.6 g/dl. Forty percent of the patients with hematochezia required a transfusion and the average transfusion amount was 4.4 packs (Pack Red Cell). Patients with nonspecific ulcers (recutum, colon), angiodysplasia, colon cancer, ilieal lesion and rectal varix required more transfusions (average transfusion amount, 5.7 packs). 3) Patients who improved with eonservative treatment only were 85.7%, and 11.4% required surgical intervention. Also 2.9% required endoscopic intervention. 4) Confirmative modalities of hematochezia included colonoscopy (80%), and others (angiography, barium enema, and operation etc.). Conclusions: In patients with hematochezia admitted to the IM Department, the cause of hematochezia was confirmed by colonoscopy and patients with hematochezia were mainly managed using conservative treatment.
지진 전조인자로서 지하수내 라돈 및 화학성분의 상관성 연구

한반도 지진에 대한 전조인자 연구를 위해 대전, 청원지역 지하수 관측정에서 심도별(-60 m, -100 m)로 화학성분과 라돈, 수위변화를 주기적으로 측정하였다. 관측정 특정심도 지하수의 pH와 전기전도도 값이 포항지진 발생에 따라 큰 폭으로 증가하는 등 비교적 뚜렷한 상관성을 보였다. 주요화학 성분 중에는 대전관측정에서는 HCO<sub>3</sub><sup>-</sup>, Cl<sup>-</sup>의 농도가 지진과의 연관성 있는 변동을 보이며, 청원지역 관측정에서는 Mg<sup>2+</sup>, Cl<sup>-</sup>, NO<sub>3</sub><sup>-</sup>의 농도가 변화를 보였다. 그러나 지하수의 주요 화학성분의 변화는 지진발생과의 상관성이 명확하지는 않다. 대전관측정 지하수내 라돈 함량은 지진 발생 전 최저 162 Bq/L에서 지진발생 직후 573 Bq/L로 크게 증가하는 경향을 보여 지진과의 뚜렷한 상관성을 보여주었다. 지하수위의 경우에는 지진발생과의 상관성은 확인되지 않고 갈수기로 인한 지속적인 하강의 양상을 보여주었다. 그러나 포항 진앙지 10 km 이내 국가 지하수 관측정에서는 지진발생 직전 뚜렷한 지하수위의 하강 현상을 보여주었다. 결론적으로 포항지진 진앙지와 약 180 km 이상 떨어진 지역이지만 대전 관측정에서 라돈가스는 지진과 가장 뚜렷한 상관성을 보여 지진전조인자로서의 신뢰성할 수 있는 후보로서 가능성을 확인하였다. pH, 전기전도도, HCO<sub>3</sub><sup>-</sup>, Cl<sup>-</sup> 성분은 지진과 일정 부분 상관성을 보여주었지만 보다 더 장기적인 모니터링을 통하여 지진전조로서 가능성을 확인할 수 있을 것으로 보인다. In order to study the earthquake precursor in the Korean peninsula, long-term variations of chemical composition, radon-222, and water level were measured at depths (-60 m, -100 m) in the groundwater monitoring wells of the Daejeon and the Cheongwon area. The pH and electrical conductivity of groundwater in the monitoring wells showed some relationship with the Pohang earthquake. The HCO<sub>3</sub> <sup>-</sup> and Cl<sup>-</sup> concentration of groundwater in the Daejeon and Mg<sup>2+</sup>, Cl<sup>-</sup> and NO<sub>3</sub> <sup>-</sup> in the Cheongwon showed some relation with the Pohang earthquake. However, it is not distinct to find the relationship between their variation and earthquake. The radon-222 concentration in Daejeon was observed a significant increase from a minimum of 162 Bq/L prior to the earthquake to 573 Bq/L right after the earthquake, that indicating a strong correlation with earthquakes. In the case of groundwater levels, it can not find some correlation between earthquakes and continuous decreasing trend in the monitoring wells of Daejeon and Cheongwon area. However, water level of a national groundwater observation well within 10 kilometers of Pohang epicenter was recorded as an abrupt drop right before the earthquake. Conclusively, although the location of monitoring wells is more than 180 kilometers apart from the epicenter of the Pohang earthquake, the radon gas in groundwater can be considered as a reliable candidate among earthquake precursors. The pH, electrical conductivity, HCO<sub>3</sub> <sup>-</sup> and Cl<sup>-</sup> among hydrochemicals showed some correlation with earthquake should be monitored during a longer term to recognize distinctly as a precursor of earthquake.
