This study was carried out to investigate the heavy metal contents and their correlations between paddy soil and brown rice near the Kum-River area. In this study, eighty soil samples and forty brown rice samples were taken from the paddy soil. The contents of heavy metals were measured by flame atomic absorption spectrophotometry. The results were as follows: 1. The average contents of soluble heavy metals in surface soil were Cd 0.19, Cu 15.31, Zn 18.10 and Pb 9.08 ppm. The average contents of soluble heavy metals in subsurface soil were Cd 0.19, Cu 14.52, Zn 17.75 and Pb8.11 ppm. There wan no statistically significant difference between the two layers. 2. The contents of Cu, Zn and Pb of Taejeon(S6) and Cd of Sinbyung(S5) in surface soil were higher than those of other areas. The contents of Cd and Cu of Taejeon(S6) and Zn and Pb of Kumnam(S3) in brown rice were higher than those of other areas and four heavy metals in soil and brown rice of Simchon(S7) were lower than those of other areas. 3. The ratio of soluble contents(Cd : Cu : Zn : Pb) in surface soil was 1 : 79 : 93 : 47, that of soluble contents in subsurface soil was 1 : 79 : 94 : 43, and that of total contents in brown rice was 1 : 84 : 294 : 12. 4. The correlations of the content between soluble heavy metals in surface(0-15 cm depth) soil total heavy metals in brown rice was found to be order of Cd>Cu>Zn>Pb. The correlations of the content between soluble heavy metals in subsurface(20-30 cm depth) soil and total heavy metals in brown rice was found to be order of Cu>Cd>Zn>Pb.

Brain size is a useful parameter describing ontogenic character and function. Despite its potential contribution to functional study and diagnosis of disease, it has been hampered by poor assessment tools in vivo and postmortem changes. Recent development of medical imaging techniques such as MRI and CT enable us to understand brain structures in vivo. Many morphometirc studies of the brain has given us new insights in the field of functional neuroanatomy and neuropsychiatric diseases. In spite of these advances, volumetric data of normal Korean brain is not available yet. As an initial approach to Korean standard brain size, we measured the cerebellar volume between 20 and 80 years old Koreans. The MRI films free from lesions in brain was analyzed and measured by NIH image program. The Korean cerebellar volume were ranged between 86.2cm(3) and 141.3 cm(3) and average male cerebellum volume was significantly larger than that of female[male : 118.2+/-11.2cm(3)] > female : 108.0+/-9.6cm(3), P=0.1021E-07<0.05]. And we could not find volume change according to aging process. This is the first report on normal Korean cerebellar volume and the presence of gender difference in the Korean cerebellar volume. These data will be used for the standard useful in studying cerebellar function and cerebellum associated disorders in the future.

BACKGROUND: To provide some fundamental physiological basis for the physical training of pilots to improve orthostatic intolerance, cardiorespiratory responses to the symptom-limited maximal exercise loading were studied in pilots and non-pilots, and the results were compared. METHOD: Cardiorespiratory reponses to the symptom-limited maximal exercise loading by Bruce protocol was studied in 11 pilots and 11 matched controls (non-pilots). RESULTS: Comparisons of various data at maximal exercise in the pilots with those in the controls revealed that RR, VE/M2, VE/VO2, VE/VCO2, VT/VC and VE/MVV as well as HR, VO2, O2 pulse and AT showed no significant difference. CONCLUSION: The fact that the aerobic power in the pilots is not superior to that in the controls seems to emphasisze the necessity of aerobic endurance training along with muscular strength training to improve orthostatic tolerance of pilots flying modern high-performance aircrafts.

OBJECTIVE: During the follow-up period of extrahepatic malignancy, one may encounter a solitary hepatic metastasis on CT scan which may be difficult to differentiate from hepatic abscess in an ambiguous clinical setting. It was our intention to copmare the radiological similarities and differences between two disease entities from which differentiation can be attempted. MATERIALS AND METHODS: Thirty-six cases of solitary heaptic meastesis and 23 cases of liver abscess were included in this study. Two radiologists interpreted the CT without knowledge of the clinical informations. CT pattern was categorized and the frequency of various findings were compared between the two groups. CT findings of the mass were analysed in misinterpreted cases. RESULTS: Without the clinical informations, the diagnostic accuracy of the mass was 72-76% without pattern analysis. Homogeneous masses were seen in both groups, but all masses larger than 4cm were metastases. In heterogeneous masses, metatases more frequently accompanied high attenuation in central or peripheral portion of the mass and showed thick intermediate zone, Irregular trabecular pattern or septations were more frequently observed in abscesses. Biliary dilatation or stone, pleural effusion, air in mass or biliary tree were more frequently seen in abscesses. The false diagnosis was encountered most frequently when the mass possessed any of the followings; homogeneous attenuation, mosaic pattern in the mass with inhomogeneous attenuation and thin intermediate attenuation area. CONCLUSION: Pattern analysis of the various CT character will be helpful to differentiate hepatic abscess and solitary hepatic metastasis in the equivocal clinical settings. However, similar pattern can be seen in both entities ;in this cases, corrdination of CT pattern and secondary findings is needed for better differentiation.

Conjunctival tuberculosis has become a rare disease in these days along with decreased incidence of systemic tuberculosis. We experienced a 43-year-old patient with large pinguecula-like protruding mass on the medial bulbar surface which was later diagnosed as conjuctival tuberculoma histopathologically. Evidence of systemic tuberculosis could not be found from any other organs of the body. This case raises the possibility that conjunctival tuberculoma may be misdiagnosed as a simple pingueculum unless histopathologic examination is performed. Brief history and clinical findings will be presented with pictures of the pathology findings, and some literatures will be reviewed.

Merkel cell carcinoma, also known as neuroendocrine carcinoma of skin is now well recognized entity of malignant skin tumor to clinicians and pathologists. A few cases have been reported up to now in the literature, but the information regarding the appropriate treatment modalities have not been obtained in detail. The clinical, histologic and ultrastructural features and the treatment of a case of primary Merkel cell carcinoma of eyelid in a 75 year-old male is presented.

Authors evaluated the retinal toxicity of high dose (2mg/0.1ml, 4mg/0.1ml) intravitreal ganciclovir injection in rabbit eye with light microscopy and electron microscopy. The results were as follows: In twenty-four hours after 2.0mg/0.1ml intravitreal injection group, edema of outer cells in inner nuclear layer were visualized under electron microscopy. These findings were disappeared after 3 days. In 4.0mg/0.1ml intravitreal injection group, edema of outer cells in inner nuclear layer were visualized at 24 hours after injection. Edema of outer cells in inner nuclear layer and axonal swelling of outer plexiform layer and upper border cells of outer nuclear layer were demonstrated at third and seventh day after injection. We observed more severe changes at seventh day than third day, and fragmentation of inner and outer segments in photoreceptor cells and presence of macrophage corresponding site of subretinal space. So, it suggests that 4.0mg/0.1ml intravitreal ganciclovir injection has mild reversible retinal toxicity.
