3.Application of software program in the ecological analysis of medicinal plants of Dao ethnic minority at BaVi commune
Pharmaceutical Journal 2001;305(9):11-13
DECODA is a ecological model. Functions of DECODA include: research, analysis and management of population and community. Master file of DECODA contains species variables, community data and sample variables. DECODA includes 3 modules: MDS, DECORANA, TWINSPAN. Applying DECODA in analyzing medicinal plant (MP) gardens of Yao ethnicity in TWINSPAN classifies 56 MP gardens into 6 groups based on characteristics of MP: I, II, III, IV groups include MPs that fit with high sunlight, heavy soil, medium moisture and poor humus soil. V, VI groups are in opposition to the above groups. DECORANA classifies the MP gardens into 7 groups based on characteristics of gardens: I, II, III, IV groups have a favourable conditions for growing MP and the owner of the gardens pay more attention in growing MP. V, VI groups are in opposition to the above groups.

This study was conducted to evaluate the relationships between the environmental exposure and biological monitoring among workers exposed to metallic mercury. We interviewed each workers to get the medical history including previous hazardous occupational history we measured the respiration rate and tidal volume of each worker in order to calculate the 8-hour inhaled mercury of workers. And we wanted to evaluate the effect of exposure duration to mercury concentrations in blood and urine as biologic exposure indices of metallic mercury. The regression and correlation analysis were done to the relationships of 8-hour inhaled mercury are mercury in blood and urine. The results were as follows; 1. The subjects were 35 fluorescent lamp manufacturing workers. The mean age of subjects was 24.8 years old, and the mean work careers of workers was 1.19 years. 89% of the total was consisted man. 2. The correlation coefficients between 8-hour inhaled mercury and mercury in blood and urine were higher than that of only considered air mercury concentration. 3. The correlation coefficients of 8-hour inhaled mercury and mercury in blood and urine were above 0.9 in workers who had exposed to mercury more than 1 year. 4. The R-square value and -value of regression analysis between the 8-hour inhaled mercury and mercury inn blood and urine was also higher in workers who had exposed to mercury over 1 year than in workers who had less than 1 year working experience. The important results or this study were that relationships between the 8hr-inhaled mercury and mercury in blood and urine was very high than that with air mercury concentration only. And the results were very apparent when considering workers 1 year or more. Therefore we concluded that the work career and respiratory volume of each individuals should be considered in evaluation the results of biological monitoring of workers exposed to metallic mercury.

One year field study of 400 lead workers on the effect of maintenance free respirator(MFR) to alleviate the lead burden revealed that MFR protection program with biological monitoring with simple measurement of zinc protoporphyrin in whole blood could be applied as an interim method to prevent lead workers from lead burden even in fairly bad working condition until fundamental environmental control will be taken in korea.
