CT was found to be highly accurate in predicting tumor size and assessing invasion of the surroundingstructures and distant metastasis. Also CT played an important role for determination of operability of esophagealcarcinoma. The CT findings with barium esophagogram in 21 patients with histologically proven esophageal carciomawere reviewed from Feb. 1985 to Feb. 1986 at the department of Radiology, Yonsei University ,College of Medicine.The results were as follows: 1. Number of patients in each stages were: 2 in stage 1, 6 in stage 2, 4 in stage 3,and 9 in stage 4. 2. Peak age distribution was in its 6th decasedes as 9 patiens (42.9%). Overall mean age was 60.8 years. Number of male patients were 19 and 2 of female. 3. Histologic types of esohageal carcinoma were 19cases of epidermoid (90.5%) and 2 cases of adenocarcinoma(9.5%). 4. The tumor location was 1 case in upper, 14cases(66.7%) in middle and 6 cases in lower one-third. 5. Various types of esophageal carcinoma were as follows: 3cases of fungating, 4 cases of infiltrating, 5 cases of ulcerofungating, and 9 cases of ulceroinfiltrating type.6. Average length of involvement in each stages were 4cm in stage 1, 5.5cm in stage 2, 8.8cm in stage 3, and 8.3cmin stage 4. The involved length was longer in advanced cases. In 11 cases(52.4%), the involved length was between4 and 8cm. 7. Angle of periaortic fat plane obliteration of the aortic circumference were as follows: Below 45degrees( 7 cases 33.3%), 45degrees-90degrees (3 cases 14.3%), over 90 degrees(11 cases, 52.4%). 8. Method oftreatment of esophageal carcinoma were as follows: Only radiotherapy in 11 cases(52.4%), radiotherapy withoperation in 5 cases, only operation in 1 cases, and no treatment in 4 cases. 9. Distant metastatic sites were:brain in 1, pericardium in 5, liver in 5, trachea in 2, bronchus in 9, and distant lymph node in 5 cases.

The relaxed G-tolerances of 16 female cadets of ROKAF academy and 19 male privates were compared. The relaxed G-tolerance level was measured as visual endpoint (gray out or loss of peripheral light loss) during G-force raise steadily at 0.1 G/s. The G-stimulations were repeated twice with the interval of 30 s for 4 days (female cadets, 9 a.m.; male privates, 10 a.m.). The correlation between the relaxed G-tolerance level and their physical factor (height, sitting height, weight and lean body mass) and muscle strength (power of abdomen, back and thigh) was investigated. The average value of the relaxed G-tolerance levels of female cadets for 4 days was significantly higher than the one of male privates (4.23 +/-0.60, n=111; 4.04 +/-0.64, n=92; student 's t-test, P<0.05). However, the training effect of 4 days was not seen in either female cadet or male private group. The weight and lean body mass have significant positive correlation with the relaxed G-tolerance level. Also, the peak torque of thigh muscle have a strong positive correlation with it, but the endurance ratio does not.

A 51-year-old female had disseminated, symmetrically distributed, brownish black pigmentation and papillary hypertrophy on the intertriginous and flexural areas for 6 months, and gastric adenocarcinoma was confirmed during the evaluation of internal malignancy, The cutaneous finding of acanthosis nigricans was a significant cutaneous marker of internal malignancy in this case.

The relationship between the intestinal histopathology and number and position of intraepithelial lymphocytes (IEL) was observed chronologically in the small intestine of rats experimentally infected with Metagonimus yokogawai. Fifteen Sprague-Dawley rats were orally infected each with 3,000 metacecariae, and 3 were kept uninfected for controls. Three rats each were sacrificed on the day 5, 10, 15, 24 and 70 post-infection (PI) and samples of the small intestine, 5 cm, 10 cm, 20 cm and 70 cm posterior to the pylorus were taken. The samples were processed routinely and stained with Giemsa. The intestinal histopathology was severe during the day 5-15 PI and characterized by villous atrophy, crypt hyperplasia, and decrease of villus/crypt height ratio. After the day 24 PI, the intestinal lesions showed some tendency of recovery. The number of IEL increased at the early stage of infection, but decreased thereafter to a lower level than that of controls, with progression of the pathological changes. Then, the IEL number began to increase again after the day 24 PI. In control rats, the great majority of the IEL were located at the basal region of the epithelium. During the early stage of infection, however, a considerable proportion of IEL was found to have moved to the intermediate or apical region of the epithelium. From the above results, it is suggested that the change of IEL number and position during the course of M. yokogawai infection should be closely related to the progression and recovery of the intestinal histopathology.

Apgar score is most widely used evaluating indicator of newborn health, but it is very subjective. Umbilical cord blood gas analysis is more objective and effective than Apgar score in evaluation of newborn status. Cord blood gas was changed slightly by processing of time after fetal birth. This study was undertaken to observe objectiveness and effectiveness of umbilical arterial blood gas analysis and effects of time interval of cord clamping to newborn health with 122 pregnant women and their babies. We observed following results: 1. There were poor correlation between Apgar score and umbilical cord arterial blood analysis in evaluating of newborn health (P>0.05). 2. There was no clinical significance of Apgar score or umbilical arterial blood gas analysis as single indicator in evaluating of newborn health (P>0.05). 3. Gas analysis and pH of umbilical arterial blood was more helpful in evaluating of newborn health than Apgar score. 4. There were no significant effects of time interval of umbilical cord clamping to newborn health. 5. If there were no indications of early umbilical cord clamping, cord blood sampling at immediately after birth without cord clamping was more effective to evaluate newborn status.

Meigs' syndrome consists of an ovarian fibroma, or fibroma-like benign tumor, associated with fluid in both abdomen and chest. Characteristically, the ascites and hydrothorax disappeared and do not recurred following removal of the ovarian tumor. The authors presented a case of Meigs' syndrome that was cured by surgical removal of ovarian tumor and resulted in normal pregnancy outcome in 27-year-old pregnant woman with a brief review of literatures.

BACKGROUND: Workers who are related with paint stripping process of aircraft parts can be exposed methylene chloride, phenol, chromium hexavalent in using paint remover. Especially, methylene chloride is more important hazard because of chemical asphyxia. METHOD: NIOSH(National Institute of Occupational Safety and Health) Manual of Analytical Methods(NMAM) #1005 was used in sampling and analysis of methylene chloride. 4 air bases were surveyed. RESULT: Airborne concentrations of methylene chloride distributed lognomally. In aircraft paint stripping operation of 4 air bases, geometric mean(GM) of methylene chloride concentrations was 30.40+/-3.39 ppm (n=14) in personal samples and GM of area samples was 2.24 ppm (n=2). 5 of 8 samples showed breakthrough phenomenon. Breakthrough rate([back section]/[front section]) significantly correlated with airborne concentrations (p<0.01) and with detected amounts of methylene chloride(p<0.01). CONCLUSION: Airborne concentrations of methylene chloride in paint stripping process exceed the criteria level in many case(43%). Seriesed charcoal tubes must be used in methylene chloride sampling in compliance with NMAM.
