OBJECTIVES: This research was intended to investigate the relationship between manganese and malodndialdehyde concentration in tissues of rats exposed to maganese chloride. METHODS: The study groups were 12 manganese treated rats and 9 control rats. Manganese treated rats were given intraperitoneally manganese chloride (Mn, 4 mg/kg) daily for a period of 30 days except Sunday. Control rats were injected 1ml of saline. The plasma manganese concentrations of rats were determined by graphite furnace atomic absorption spectrometry. The tissue manganese concentration was determined by flame atomic absorption spectrometry. Malondialdehyde, the product of lipid peroxidation was determined by ultraviolet-visible spectrophotometry. The plasma malondialdehyde was determined by gas chromatography with mass-detector. Protein concentration was quantified by ultraviolet-visible spectrometry and was used for the compensation of tissue malondialdehyde and manganese concentration. RESULTS: Manganese concentrations of plasma, brain, liver, and pancreas were very significantly higher in the manganese-treated rats than in the control rats. Malondialdehyde concentration of plasma, brain, and pacrease were significantly higher in the manganese-treated rats than in the control rats. The concentration of malondialdehyde was correlated with manganese levels in plasma, brain and pancreas. Conclusion: Based on the results obtained as above, it was concluded that the malondialdehyde, product of lipid peroxidation was related to the cell death due to dosing excess manganese.

Isolated situs in versus of the stomach with otherwise normal position of the thoracic and abdominal vescera isan extremely rare anomaly occurring in two distinct forms. Majority of cases are associated with eventration of the diaphragm and are reported as being confused with spontaneous pneumothorax of pyopneumothorax at base of the right lung. The right sided stomach may produce interesting and confusing changes in liver scan. We have experienced 2 cases of the isolated dextrogastria.

Injuries are serious problem common to all societies. Yet even within a single community, groups of injured persons differ as to the nature and severity of their injuries. The difficulty of adjusting for such variations has hampered scientific study of injured persons. Neverthless it is essential to take differences in severity of injury into account when comparing the morhidity & mortality of various groups for the purpose of evaluating their emergency & subsequent care. In order to provide the guidelines of mass emergency care & transportation, the authors analysed the 206 injured patients of train accident at Kyungsan, May 14th, 1981 and compared mortality with severity and body system of the injuries. The results were obtained as follows: l. Of 206 injured patients, most were young people & the ratio of male & female was about equal. 2. Extremities were the most frequently injured parts of body system & single injury was more common. 3. According to most severe injury of AIS, 78% of injured persons belonged to below AIS grade 3 and none was dead. 4. Average ISS of survival groups was 6 and that of death groups was 34. None was dead below average ISS of 15. 5. Death rate was higher for patients above 50 years of age, than that for young patients and there was no age difference in mortality for ISS of 50 and higher. 6. Majority of death group were invclved in multiple injuries and major cause of death were chest and head injuries. 7. Average ISS and age of hospital death group were less than those of DOA group. 8. The authors thought that it was necessary to estahlish Emergency Service System including training and education of both professionals and the pulic, hospital categorization, communication and transportation system for the mass emergency care.

To evaluate the efficacy of STIR (short tau inversio recovery) image in the diagnosis of orbital diseases, we compared the STIR images with conventional SE(spin-echo) images in 17 patients. The fat signal was reliably nulled at inversion time of approximately 160-170 msec in all cases. We analyzed all the cases in the aspects of the detection of lesion and the lesion-to-back ground contrast retrospectively. Regarding lesion, the detection rates of STIR, T1 and T2-weighted images were 89, 88 and 83% respectively. In the aspect of lesion-to-background contrast, the contrast ratios of STIR and T1, T2-weighted image were 87% and 64, 56%, respectively. In conclusion, STIR images were similar to T1-and T2-weighted images in the detection of lesion, but superior in the aspect of lesion-to-background contrast. So the STIR images may be a useful adjunct to conventional SE images for the diagnosis of orbital disease.
