The main goals of the study were to investigate the sediment quality and trace metal distribution in sediment of Kwangyang Bay, south coastal of Korea. Surface sediment sampling were performed in November, 2000 and February and March, 2001. The concentration of H₂S, IL and COD in sediment were measured by a manual of the Department of Marine Environment of Korea. The extracted trace metals Fe, Cu, Cd, Pb, and Zn in sediments mean analyzed by the flame atomic absorption spectrophotometer with an instrument of model Shimadzu AA-6701F. H₂S, IL and COD in the surface sediment were 1.3 mg/g, 5.9 % and 15.0 mg/g, respectively. The mean content of Fe, Cu, Cd, Pb and Zn were 1523 mg/kg, 4.799 mg/kg, 1.321 mg/kg 9.285 mg/kg and 9.353 mg/kg, respectively. All of these measured trace metals level were over the other reported trace metal level in sediment of coastal area. According to histograms, the content of H₂S, IL and COD and trace metals in sediment of this study were affected by artificial activities rather than natural process.

Benign neural sheath neoplasms are not common in the maxillofacial region. These lesions can occur as solitary tumors, or they can affect many sites in the form of multiple neurofibromatosis. A solitary neurofibroma is seldom undergo sarcomatous transformation, since solitary neurofibroma is relatively radioresistant and its recurrence rate seems to be low, the treatment of choice is surgical excision. This case showed a solitary neurofibroma in the left side of the floor of mouth which occurred in a 33 - year -old female. The tumor was excised. And there is no evidence of disease. She is satisfied in function and esthetic aspect.

Streptococcus mutans is known as the causative bacterial playing the most important role in forming plaque and it is being noticed as major causative bacteria of dental caries. Therefore, development of more effective, substantial and safe preventive agent against dental caries and periodontal disease is honestly required. The present study was designed to investigate the effect of chloroform extract(CE), n-butanol extract(BE),methanol extract(ME) and water extract(WE) of Caesalpinia on the growth, acid production, adhesion, and insoluble glucan synthesis of Streptococcus mutans. The CE, BE, ME and WE decreased the growth and acid production of S.mutans than that of control, especially, the ME was more effective than other extracts. The effect of CE, BE, ME and WE on the adherences to saliva-coated hydroxyapatite bead(S-HA) were evaluated. At the concentration of 2,000 ㎍/㎖, the CE showed 32% rate of bacterial adherence to S-HA, whereas, other extracts of the same concentration producedgreater than 50% rate. The CE and BE were significantly decreased the reduction rates of water insoluble glucan formation from sucrose by crude glucosyltransferase of S.mutans. Thus, the application of C. sappan can be considered a useful and a practical method for the prevention of dental caries.

The purpose of the survey was to study of anthropomeric measurements of elderly in Jeon-Ju area. One hundred seventeen (males 36, females 81) subjects aged from 65 years to 74 years. The average height and weight of the subjects were 164.1cm and 61.1kg in males and 151.6cm and 54.1kg in females. Height and weight in males were significantly higher than in females(p<0.001). W/H is also significantly higher in males than that of females(p<0.01). This indicates that fat distribution of males tend to be centralized toward the trunk of the body than females. But, ST, BFW and BF(%) in females were significantly higher than in males. The subjects were classified as 16.2%, 26.5% and 26.5% obesity by BMI, OR and PIBW, respectively. The subjects were classified as 16.2%, 26.5% and 57.3% overweight by BMI, OR and PIBW, respectively. The subjects were classified as 7.7%, 0% and 0% underweight by BMI, OR and PIBW, respectively. In males, obesity index(BMI, OR, PIBW) were strong positively correlated with waist(p<0.001). In female, obesity index(BMI, OR, PIBW) were strong positively correlated with BFW, hip(p<0.001).

<P>The fruits of Cornus officinalis have been used in traditional oriental medicine for treatment of inner ear diseases, such as tinnitus and hearing loss. In the present study, we investigated the protective effect of C. officinalis on hydrogen peroxide-induced cytotoxicity in HEI-OC1 auditory cells. The results from bioassay-guided fractionation of methanol extract of C. officinalis fruits showed that ursolic acid is a major active component. Ursolic acid (0.05-2 μg/ml) had protective effect against the HEI-OC1 cell damage and reduced lipid peroxidation in a dose-dependent manner. In addition, pre-treatment with ursolic acid significantly attenuated the decrease of activities of catalase (CAT) and glutathione peroxidase (GPX), but superoxide dismutase (SOD) activity was not significantly affected by ursolic acid. These results indicate that ursolic acid protects hydrogen peroxide-induced HEI-OC1 cell damage through inhibition of lipid peroxidation and induction of antioxidant enzymes, CAT and GPX, and may be one of the active components responsible for these effects of C. officinalis fruits.</P>
