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.

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.

This study was undertaken to investigate the skin sensitivity to 54 different allergens in 248 patients of 81 acute urticaria, 141 chronic urticaria and 26 atopic dermatitis, who visited in Department of Dermatology, College of Medicine, Chung Ang University Hospital from February 1986 to January 1987. The results were as follows . 1. The sex ratio of male to female of 248 patients with allergic state was 1.1: 1 (130: 118) and third and fourth decades occupied 56.5%. In regard to the duration of chronic urticaria, less than 1 year were 31.2% and between 1 to 3 years were 28.3%. 2. In acute urticaria, the prick test positive reactivity to allergens were in descending order to mite, household insect mixture, Trichophyton mixture, house dust, mold mixture C and silk, whereas in chronic urticaria ', mite, household insect mixture, house dust, cockroaeh mixture, Trichophyton mixture and silk and in atopic dermatitis ; mite, house dust, Trichophyton mixture, household insect mixture, mold mixture A and C. 3. The positive reactivities of allergens in patients with atopic dermatitis, chronic urticaria and acute urticaria were 69.2%, 52.5% and 35.8%, respectively. 4. The positive reactivity to compound allergens were higher than to single and the most frequent combinations were 2 to 5 allergens (85.4%). 5. Out of 54 allergens used in this study, 49 allergens were reactive and the most frequent group of allergens were house dusts (41.5%) and commonly involved allergens were mite (27.8%), household insect mixture (15.7%), house dust (13.7%), Trichophyton mixture (11.7%) and cockroach mixture(7.7%). 6. Common other allergic diseases combined with atopic dermatitis were rhinitis and bronchial asthma, occuring in 23.1%.

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.

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.

Technology for the long-term preservation of gamete and embryo has improved greatly over the past 20 years and currently is used for supporting various assisted reproductive technologies (ART). Recent progress in cryobiology and its related sciences have made it possible to preserve human embryos effectively, and several cryopreservation methods also have been developed. Successful freezing of supernumerary embryos has allowed patients undergoing ART the opportunity to achieve pregnancies from more than one embryo transfer without being subjected to controlled ovarian hyperstimulation and oocyte retrieval each time. It also allows a delay in embryo transfer where certain adverse conditions exist for fresh transfer, e.g. when the patient is at risk for ovarian hyperstimulation syndrome or when there is poor endometrial development during the retrieval cycle. Cryopreservation of all available embryos from retrieval is utilized when an oocyte recipient is not properly synchronized with oocyte donor's cycle. In this paper is to review the current status and perspectives of embryo cryopreservation in ART program. Also, briefly discuss the oocyte cryopreservation for the establishment of ovum bank.
