The aim of this study was to evaluate the effect of mouthrinse products containing deep sea water. We used original deep sea water (DSW) and processed deep sea water desalinated by reverse osmosis at one time (DDW-1), by reverse osmosis at two times (DDW-2) and concentrated by reverse osmosis (CDW). We made 2 kinds of mouthrinse products containing CDW and other agents for smell and taste and one product without deep sea water. The negative control was distilled water. In vivo study, the dental plaque index scores and the gingival index scores were reduced after 4 weeks mouthrinsing three times daily with 4 kinds of deep sea water and 3 kinds of mouthrinse products(p<0.05). The pH of dental plaque in 1 minute after mouthrinsing was not higher than 5.5 in all solutions, but the pH in 20 minutes after mouthrinsing was higher than 5.7 in DSW, CDW and 3 kinds of products which had higher mineral contents. In vitro study, the mouthrinse solutions containing the higher mineral contents were also the more effective in reduction of methyl mercaptan which is one of the causes of halitosis. The 2 kinds of products containing deep sea water killed Streptococcus mutans (ATCC 25175) in culture plates in one minute. These results indicate the usability of deep sea water in mouthrinses for oral hygiene management.

In order to evaluate the status of cold exposure and its health hazards of workers at cold storage workplaces and to provide basic data for effective health care, the author measured core temperature and also observed clinical symptoms and signs, past and present history, and general health examination data on 99 cold exposed workers for exposure group and 96 non-exposed workers for control group working at 2 food refrigerating companies in Pusan area from January 6, 1998 to February 24, 1998. The results were as follows : 1. There was statistically significant difference in water intake between the exposure and control group and increased urine volume, urine frequency in exposure group without statistically significant difference. 2. Past and present illness in exposure group were hypertension (18.2%), hepatopathy(8. 1%). gastro-intestinal disease(7. 1%). arthritis (4.0%), intervertebral disc herniation(4.0%). and so on, and hypertension, arthritis was statistically significant difference compared to control group. 3. Symptoms inexposure group were. fatigue(89.9%), headache (64.6%), drowsy(63.6%), neck stiffness(59.6%), excessive food intake (59.6%). general weakness(58.6%), hunger(58. 6%), numbness(54. 5%), and so on, and there was statistically significant difference between the exposure and control group except fatigue, drowsy. 4. As results of clinical test abnormality rate of the systolic, diastolic blood pressure and electrocardiogram were significantly higher in exposed group that control. 5. Core temperature in exposure group was statistically significantly lower than control group and the highest statistically significant inverse correlation with the working hours and working frequency of daily mean cold storage. As above results, the author suggested that the further studies should be conducted to evaluate the health status of workers about chronic health effects in cold workplaces and to establish effective health care methods for them.

We analyzed parasitic diseases diagnosed by tissue biopsy specimens at KyungHee Medical Center (KMC) from 1984 to 2005. The total number of parasite infection cases was 150 (0.07%) out of the total 211,859 biopsy specimens submitted for histopathological examinations. They consisted of 62 cysticercosis, 23 sparganosis, 16 paragonimiasis, 15 amebiasis, 11 anisakiasis, 11 clonorchiasis, 3 ascariasis, 2 scabies, 2 enterobiasis, 2 trichuriasis, 1 leishmaniasis, 1 taeniasis, and 1 thelaziasis. Out of 62 cysticercosis cases, 55 were detected in subcutaneous tissues or the central nerve system. Eighteen out of 23 sparganosis cases were involved in muscular and subcutaneous tissues. In most anisakiasis cases, the involved organ was the stomach. The lung and the pleura were the most common site of paragonimiasis. The incidence of parasitic diseases during the first 5 years (1984-1988) was the highest of all observed periods. After 1989, similar incidences were shown throughout the period. Whereas cysticercosis was diagnosed in 34 cases during 1984-1988, no case has been diagnosed since 2000. In the case of sparganosis, the chronological incidence was almost uniform throughout the period 1984-2005. Paragonimiasis showed a similar tendency to cysticercosis. In gender and age distribution of parasitic diseases, men showed higher incidence rates than females, and the age groups of the 40s or older indicated higher infection frequencies than other age groups. Therefore, these results are a significant report to appear the tendency of human parasitic disease diagnosed by tissue biopsy in association with parasitosis at KMC in Seoul.
