Objective : Radiofrequency facet rhizotomy[RFFR] has been widely performed for treatment of chronic neck pain caused by cervical dorsal ramus syndrome[CDRS]. To evaluate the therapeutic effectiveness of RFFR in the patients with CDRS, we analyzed patients with various cervical pathologic conditions. Methods : The therapeutic results in forty-four patients who underwent RFFR for CDRS from January, 2000 to December, 2002 were analyzed according to the underlying pathologic conditions causing CDRS. The pathologic conditions were sprain [33 cases], herniated nucleus pulposus [6], foraminal stenosis [4], and compression fracture [1]. The therapeutic results were evaluated one month after the operation and graded as excellent, good, fair of poor. Treatments were considered successful if the therapeutic results were graded as either excellent of good. Results : The overall success rate in all patients was 72.7%. The success fate for treatment of cases with cervical sprain was 87.9%, but treatment of cases with herniated nucleus pulposus, foraminal stenosis, and fracture showed unsatisfactory results [mean success rate was 27.3%]. Some patients complained of transient hypesthesia [4 cases] of transient dull pain at the electrode insertion sites [2 cases]. Conclusion : RFFR is an effective and safe treatment for CDRS caused by cervical sprain, regardless of the patient's age, the duration of the symptoms, and the presence of radiating pain.

담도암은 서서히 자라며 원격전이가 늦은데 비하여 완전절제가 어렵고 수술 후 재발율이 높아. 생존율은 매우 낮다. 많은 예에서 국소치료의 실패가 치료실패의 요인으로 밝혀짐에 따라 술후 방사선 치료의 중요성이 인정되어 왔다. 외부방사선치료 만으로는 충분한 선량을 조사할 수 없으므로 국소적인 고선량치료법으로서 술중방사선치료, 간질방사선치료 (interstitial irradiation), 경관방사선치료(transcatheter irradiation) 등이 사용되고 있으나 경관방사선치료의 보고는 드물다. 영남대학병원 치료방사선과에서는 진행된 담도암 1예에서 암 종괴의 부분절제 후 삽입된 T-자관을 통하여 고선량 방사선 치료를 실시하였기에 문헌고찰과 함께 보고하는 바이다.

In the case of designing a high dose rate remote controlled afterloading treatment room with existing hospital facilities. We must construct the effective protective barriers so as to reduce the primary and scattered radiation up to the maximum permissible dose level. It is difficult to reinforce the barrier thickness of the shielding requirements because of the limited space and the problem of the existing building structure at the surrounding area. Therefore we can reduce the intensity of primary radiation to the required degree at the location of interest with installing the appropriate I shaped Pb barriers between the radiation source and the shielding wall of the concrete. As a result, it was possible to reduce the intensity of the primary radiation below the M.P.D level by using additional Pb barriers instead of increasing thickness of concrete wall.

Rebamipide, 2-(4-chlorobenzoylamino)-3-[2(1H)-quinolinone-4-yl]-propionic acid, a novel antipeptic ulcer agent, has been reported to prevent various acute experimental gastric mucosal lesions and to accelerate the healing of chronic ulcers. Therapeutic effect of rebamipide was investigated with regard to the inhibitory effect on xanthine oxidase activity and type conversion of the enzyme which play a profound role in oxygen radicals generation system. Intraperitoneal administration of rebamipide at 60 mg/kg body weight reduced the xanthine oxidase activity, lipid peroxide content in ammonia induced hemorrhagic lesion. These results suggest that the therapeutic effect of rebamipide on gastric mucosal lesion may be in part due to the inhibitory activity of xanthine oxidase and type conversion rate of the enzyme.

Radiation treatment results were analyzed in a retrospective analysis of 47 patients with pituitary adenoma treated with radiation alone or combined with surgery from 1974 through 1987 at the Department of Therapeutic Radiology of Kyung Hee University. The 5-year overall survival rates for all patients was $80.4\%$ Radiation therapy was effective for improving visual symptoms and headache, but could not normalize amenorrhea and galactorrhea. There was no difference of survival rate between radiation alone and combination with surgery. Prognostic factors such as age, sex, disease type, visual field, headache and surgical treatment were statistically no significant in survival rates of these patients.

To confirm diagnosis and to set proper therapeutic strategy, open lung biopsies were done in 57 patients who were suspected for diffuse interstitial lung disease from January 1985 to December 1994. Among them, 35 were male and 22 were female[M:F=l.6: 1 and mean age of the patients is 53.5$\pm$ 2.3[24-81 years. Tissue for histologic studies were obtained from left lung in 33, from right lung in 24according to the distributions of the pathology. Preoperative diagnostic work-up`s were chest X-ray, CT[HRCT scan, sputum study, bronchoscopy[BAL, TBLB and PTNA and all of them were unsuccessful to confirm diagnosis. In comparison of pulmonary function tests between preoperative and postoperative values, there were no significant differences in FVC, FEV1, FEV1/FVC[p 0.05 but in AaDO2[p[0.05 . Postoperative complications including atelectasis, wound infection, pulmonary edema and respiratory insnfficiency, were shown in 5 cases[8.8% , and two of them were died of respiratory failure and sepsis[mortality rate 3.5% . Pathologic diagnosis was confirmed in 53 cases postoperatively but it was undetermined in 4[diagnostic yield rate 93.0% . In comparison between preoperative clinical diagnosis and postoperative pathologic diagnosis, new diagnosis were made in 17 cases[29.8% and preoperative tentative diagnosis were confirmed histologically in 36 cases[63.2% . In 4 cases[7.0% , however, diagnoses were not confirmed after biopsies. Therapeutic plans were reset in 46 cases[80.7% in accordance with the final diagnosis.In conclusion, open lung biopsy is recommended for a specific diagnosis and proper therapeutic plan in diffuse interstitial lung diseases because of its high diagnostic yield Irate and it`s relatively low morbidity and mortality rate in these tompromised patents.

This study was carried out to prove the therapeutic effects of BNJB on the catract. The objects of this study were CXSD mice that spontaneously eye rupture occurred from three weeks after birth and eventually generate cataract within 12 weeks. We applied eyewash made from BNJB to eyes of CXSD mice twice in a day till all the eyes of the negative control showed up the symptoms of a cataract and recorded the increasing patterns of cataractous eyes. To explained the therapeutic effects of the BNJB, We carried out the ex vivo experiment which cultivating eyeballs were offered oxidative stress condition by $0.03{\%}$ $H_2O_2$ during three days. Total co-enzyme was extracted from the cultured eyeballs and used to measure activities of catalase, superoxide dismutase, glutathion S-transferase and content of GSH. The results were obtained as follows: 1. When we treated the catalin to CXSD mouse as a positive control, it represented the delaying effect for cataract generation for 2-3 days compare with negative control. But it seems that it doesn't appropriate as a therapeutic, or delaying agent. 2. In the experimental BNJB group, Cataract formation rate was dramatically reduced by BNJB. This rate was much lower than positive group and means our new formulation for the therapy of cataract has a good potential. 3. In the analysis of individual medicines of BNJB, Mok-Jeok-Cho, Hwang-Lyun and Ha-Go-Cho didn't have a major effect of BNJB. 4. The cataract formation rate was repressed by Bing-Pyun and Jin- Joo-Boon about $40{\%}$ and $50{\%}$, respectively. We can presume that the anti-cataract effect of BNJB was caused by these two medicines. 5. When we surveyed the anti-oxidant activities of BNJB, enzyme activities of GSH, SOD, and Catalase increased about $10{\%},\30{\%}$, and 2.5 folds, respectively.
