This Study was performed to investigate the effect of foods containing benzoic acid on the urinary hippuric acid concentration in the toluene exposed workers. The urinary hippuric acid concentration were measured at 0, 30, 60, 90, 120, and 150 minute after intake of soft drink and bread containing benzoic .acid: in volunteers,: who did not have been exposed toluene occupationally. After that urinary hippuric: acids also were measured at the end of shift in toluene exposed workers. And also the concentration of toluene in air were analysed! by gas chromatography. So the relationships between urinary hippuric acid concentration and age, work duration, concentration of toluene in air and intake of benzoic acid containing food were observed. The results were as follows: 1. The urinary hippuric acid concentration reached the highest level at 30 minute after intake of soft drink with bread at a level of 1.41g/g creatinine and soft drink; alone at a level of 1.04g/g creatinine which contained benzoic acid among unexposed toluene, and then gradually decreased. 2. In toluene exposed group no significant effect of general; characteristics siich; as gender, age, work duration, drinking and smoking on urinary: hippuric acid concentration was showed in toluene exposed group. 3. The mean value of urinary hippuric acid concentration of group taking benzoic acid containing foods was significantly higher than that of group not taking. 4. Multiple regression analysis showed that toluene concentration in .air and benzoic acid containing foods were together significantly influence on urinary ; hippuric acid concentration. And the function between variables is Y = 0.014Tpluene +0.489Benzoic acid +0.745 and the contribution rates were 31%. In conclusion, it was suggested that the information on intake of benzoic acid containing foods should be considered in measurement of urinary hippuric acid for the more accurate toluene exposure evaluation.

One hundred eighty-six cases of ovarian common "epithelial" tumor including 28 endometriosis were reviewed, from the pathology file of the department of pathology of the National Medical Center during a period of 8 years and 6 months from January 1976 to June 1984. The study consisted of 14 cases(77.4%) of benign tumor including 28 cases of ovarian endometriosis, and 21 cases(11.3%) of borderline malignancy and 21 cases(11.3%) of invasive malignant tumors. Among benign common "epithelial" tumors, mucinous cystadenoma(69 cases) was the most frequent tumor, followed by serous cystadenoma (42 cases) and Brenner tumor (5 cases). Of borderline tumor, borderline mucinous tumor (18 cases) was more frequent than serous tumor (3 cases). Serous cystadenocarcinoma(9 cases) was the most frequent malignant tumor, followed by mucinous cystadenocarcinoma(6 cases), endometrioid carcinoma(3 cases) and undifferentiated carcinoma(3 cases). Most ovarian common "epithelial" tumors were prevalent during the reproductive age, but malignant tumors were more prevalent after the age of 40. Although right side was more frequently found (85 vs. 67) there is no significant site predilection. Bilaterality was the most common in undifferentiated carcinoma(66.7%), followed by serous cystadenocarcinoma(44.4%) and Brenner tumor(40%). The size of tumor tended to be larger in malignant tumor than benign. Mucinous tumor were usually larger than serous tumor. There were 7 intrauterine and 1 ectopic tubal prognancy which were associated with ovarian common "epithelial" tumors. Three cases of tumors were excised during Cesarian section. In summary these findings are comparable to other reports in Korea and English literatures. Histologic analysis of borderline and malignant epithelial tumor was done to emphasize their biologic behavor. Further study is required to compare their histological grading and clinical staging with thier survival rate.

The double pylorus-is a fistulous communication between the gastric antrum and duodenal bulb, usually extending from the lesser curvature of the stomach to the superior aspect of the duodenal bulb, and seperated by septum or bridge of normal mucosa. Although its incidence is rare, reports concerning double pylorus are increasing with the recent development of upper gastrointestinal endoscopy and more awareness of this abnormality. We recently experienced two cases of double pylorus; an aquired one in 72-year old male who had an another opening with healing ulcer at the superior aspect of the original pyloric channel, central erosion with clubbing and fusion of mucosal folds at the greater curvature of the lower body and a 3 x 4 cm sized ulcer at the lesser curvature of the lower body, and the other congenital one in 53-year old male who had an another opening at the superior aspect of the original pyloric channel with histologically intact muscularis mucosa in the pyloric septum with no evidence of chronic peptic ulcer scarring. We report here two cases of double pylorus, one-acquired, and the other-congenital, with a review of the literature.

It is reported that amniotic membrane easily obtained from human body was effective to treat ocular surface disease. Authors treated pterygium, which is known to high recurrect rate, with amniotic membrane transplantation, and evaluated its effect. From June 1997 to March 1998, 28eyes(18 eyes of primary pterygium, 10 eyes of recurrent pterygium)were treated with amniotic membrane transplantation. As the results shows higher recurrent rate(4 eyes of 18 eyes(22%) in primary pteygium, 3 eyes of 10 eyes(30%)in recurrent pterygium), so amniotic membrane transplantation was less effective method to treat primary and recurrent pterygium than other method like conjunctival autograft.

An unusual case of intraspinal peripheral neuroepithelioma arising from the cauda equina is reported. The patient, a 21-year old female, suffered from low back pain with radiation to the posterior aspect of both legs. Myelographic, computed tomographic scan and magnetic resonance imaging studies of lumbosacral spine showed the intradural extramedullary mass lesion on the L3-S1 level which was excised surgically, but recurred rapidly. It could be diagnosed by the histopathologic findings. The postoperative radiotherapy and chemotherapy were administered. We report this rare case with review of the literatures.

There are considerable discrepacies between clinical symptoms and imaging diagnosis in the localization of the responsible radiculopathy. The purposes of this study are to analyzed the dynamic alteration of contrast filling of the spinal nerve sleeves during positional changes and to determine how the abnormalities of nerve sleeves no lateral bending A-P views correlate with sciatica. The criteria indicationg the root abnormality in functional myelography were (1) bad filling of ipsilateral root to sciatica and (2) good filling of contralateral root compared with those in neutral A-P view. Of total 77 patients, 67 had radiculopathy and 10 had no radiculopathy. In 23 (34.3%) of 67 patients with radiculopathy and 6 (60%) of 10 patients with no radiculopathy, their clinical symptoms well correlated with conventional myelographic findings. However, in 35 (52.2%) of 67 patients with radiculopathy and 6(60%) of 10 patients with no radiculopathy, their symptoms well correlated with functional myelographic findings. This study suggests that the functional myelogaphy using both lateral bending A-P views can be used as a complementary tool in the evaluation of the radiculopathy.
