Santonin-kainic acid complex was evaluated as a chemotherapeutic of the mass treatment of the Ascaris lumbricoides infection in Korea. The results could be summarized as follows: The negative conversion rate was 82.9% in average in 4 treated groups. Some variations of negative conversion rate among the treated groups were noticed. The egg reduciton rate was 97.7% in average and the results were rather uniform among the three evaluated groups. By the analysis of egg reduction, it seems that the lightly infected cases whose E.P.G. were under 5,000 were resistant to treatment with the less reduced egg output. After the treatment with this complex, the number of egg discharged cases were reduced to 1.84% and the average number of discharge eggs per incompletely treated or untreated cases were reduced to 12.5% compared with the level of before-treatment egg output. The successive observations of the pattern of worm expulsion after drug intake was made. The worms were mostly expelled in the stool within 3 days, and 58.9% of total expelled worms were collected within 24-hour stool. The minimum length of the immature worms expelled was 7.6cm. Among the 659 Ascaris collected in the first-day stool from 91 rural people, 8.5% were in the range of 7.6-12.2 cm-long, immature worms. The sex ratio, male: female= 0.69: 1.

OBJECTIVES: Over the last 30 years, despite the increasing sophistication in medical care, the mortality of acute renal failure(ARF) has remained virtually unchanged at 40-50%, but the reasons remain unknown. This study intend to identify prognostic risk factors influencing survival and predict the mortality in ARF patients. METHODS: We retrospectively analyzed 152 patients with ARF who required renal replacement therapy, or whose serum creatinine level above 5 mg/dl, from Jan. 1988 to May. 1995. Multiple factors which may influence mortality were evaluated by univariate and multivariate analysis. RESULTS: 1) Of the 152 patients, 97 were male and 55 were female. The mean age was 47 years and the overall mortality was 36.8%. 2) Based on the univariate analysis, age>60 years, cause of ARF, APACHE II score, number of failing organs, peak serum creatinine level, PaO2, coma, hypotension, ARDS, GI bleeding, ventilatory support, need for antiarrhythmics, DIC, cardiovascular failure, pulmonary failure, neurological failure, and gastrointestinal failure were all significant factors discriminating between survivors and nonsurvivors(p<0.05) 3) By multivariate analysis, hypotension, coma, ventilatory support, and age over 60 years were significant independent predictors influencing survival in ARF patients and logistic equation and logit score were as follows : z=-2.04+1.32(age over 60)+2.18(hypotension)+2.88 (ventilatory support) + 3.28(coma) P=ez/(1+ ez) 4) In ROC(receiver-operating characteristic)curve, when the cutoff point was 0.2, maximum sensitivity was 75% and maximum specificity was 82%. CONCLUSION: In ARF, prognostic risk factors for mortality were age over 60 years, hypotension, assisted ventilation and coma. The logit score by multiple analysis is a reliable predictor of mortality in ARF patients, however the further studies are required to confirm these results.

PURPOSE: To evaluate the effect of topical cyclosporine 0.05% (Restasis; Allergan, Irving, CA, USA) on tear osmolarity in patients with dry eye disease. METHODS: The present study was a single-center, randomized, prospective, and longitudinal trial. Patients who had been using artificial tears to treat dry eye disease were prescribed cyclosporine 0.05% and evaluated using tear osmolarity, tear break-up time, ocular surface staining score, Schirmer test, and the Ocular Surface Disease Index for symptomatic improvement. Clinical measurements of commonly used objective tests were performed at baseline and after 1, 3, and 6 months. RESULTS: At the end of the study, patients demonstrated statistically significant improvement in tear break-up time (6.26 +/- 1.26 sec at 3 months vs. 4.41 +/- 1.63 sec at baseline, p = 0.022) and OSDI (34.98 +/- 20.19 at 3 months vs. 45.02 +/- 22.38 at baseline, p = 0.032) only at 3 months. Other measures such as Schirmer test, ocular surface grade, and tear osmolarity also showed improvement. However, the differences were not significant. CONCLUSIONS: Over a 6-month period, topical cyclosporine 0.05% showed beneficial effects on symptoms and other commonly used signs of dry eye disease for 3 months; however, the tear osmolarity values were not significantly improved.

A case of metastatic alveolar soft part sarcoma is presented with clincal, pathological and radiological features. Alveolar soft part sarcoma is a rare soft-tissue neoplasm that is malignant and invariably fatal. It was first described and named by Christopherson, et al. in 1952. Since 1952 numerous examples of this tumor have been reported and have been studied with the electron microscope, but there is still considerable uncertainty as to the exact histogenesis of the tumor. Most cases occur in young females involving the lower extrimities especially in the right side. The most initial presenting symptom is a slowgrowing painless mass and the principal metastatic sites are the lungs, followed by the brain and skeleton. Cerebral metastasis, in fact, may be the first manifestation of the disease. Treatment is radical surgical excision but radiotherapy and chemotherapy are less effective. We present the reported case of metastatic alveolar soft pat sarcoma with electron microscopic findings.

PURPOSE: Percutaneous needle aspiration biopsy under the imaging guidance in the diagnosis of intrathoracic diseases has become a standard practice. Core tissue obtained by automated gun biopsy(AGB) is believed to be more diagnostic than materials from fine needle aspiration(FNA) by many cytopathologists. The authors evauated the role of automated gun biopsy in localized pulmonary lesions with respect to the its accuracy and complications. MATERIALS AND METHODS: We performed 107 percutaneous biopsies in localized pulmonary lesions under fluoroscopic guidance among 107 patients:AGB using 18G or 20G was done in 81 patients, and both AGB and FNA was done in 26 patients. RESULTS: Biopsy samples sufficient for histologic diagnosis were obtained in 94(87.9%) of 107 patients, AG8 in 73(90.1%) of 81 patients and AGB and FNA in 21(80.8%) of 26 patients. 11 of 13 negative results were due to inadeguate specimen size for the histologic diagnosis or were composed of necrotic areas, and 2 of 13 negative results were obtained through nontarget tissue. 10 patients developed pneumothorax and 4 of them required chest tube insertion. Minimal hemoptysis was found in 3 patients. CONCLUSION: Percutaneous automated gun biopsy under fluoroscopic guidance was easy and simple method of obtaining specimens of good quality and quantity. It may be an useful procedure in the diagnosis of localized pulmonary lesions.

PURPOSE: To compare the results of transepithelial photorefractive keratectomy (trans PRK) and brush-assisted photorefractive keratectomy (brush PRK) for the treatment of myopia. METHODS: A total of 146 eyes from 78 patients who received brush PRK or trans PRK with the Schwind Amaris laser platform were included in the present study. Uncorrected distance visual acuity (UDVA) and manifest refraction spherical equivalent (MRSE) at postoperative 1 week, 1, 3, 6, and 12 months were compared between the 2 groups as well as epithelial healing time. RESULTS: The mean time to complete epithelial healing was 3.27 +/- 0.75 days in the trans PRK group and 3.67 +/- 0.93 days in the brush PRK group (P < 0.05). At 1 week after surgery, UDVA recovered more rapidly after trans PRK than brush PRK (brush PRK: 0.13 +/- 0.12 log MAR units, trans PRK: 0.09 +/- 0.08 log MAR units, P < 0.05), however, UDVA was not significantly different at 1, 3, 6, and, 12 months postoperatively between the 2 groups. CONCLUSIONS: Re-epithelialization and visual recovery were faster in the trans PRK group while visual outcome and postoperative complications were equivalent to the brush PRK group.

The purpose of this study is to evaluate an antioxidative effect of estrogen on the bone in oophorectomized rats. Thirty Sprague-Daley rats were equally divided into 3 groups; group 1 as control group with sham operation, group 2 as experimental group with oophorectomy, and group 3 as oophorectomized group treated with estrogen. Estradiol (5mg/kg BW) was administered three times per week from first to sixth week after oophorectomy. Left tibia was obtained to measure the amount of protein carbonyls as an index of oxidative stress and the activity of antioxidant enzymes. The results were as follows: trahecular bone area in proximal tihia decreased after oophorectomy, which increased in response to estrogen administration. The level of protein carbonylation in hone was not significantly different among all groups. Activity of antioxidant enzymes such ais glutathione reductase(GR), glutathione peroxidase(GP) and glutathione transferase(GST) in bone was not significantly different among all groups. However, the activity of catalase in bone markedly increased in group 3 compared with that in group 1 and group 2. In summary, bone trabecular area increased after admin- istration of estrogen. And estrogen induced the activitv of catalase, which might contrihute to prevent the oxidative damage. However, the glutathione utilizing enzymes such as GR, GP and GST were not significantly affected by estrogen status.
