Objective In order to analysis the relation between salt iodine and the urinary iodine level in the pupil of Sichuan province, and to evaluate the preventive effect of iodine deficency disorders(IDD) in Sichuan province.
Conclusion The prevention of IDD achieved obvious effect. But the monitoring result of iodated salt in 1997,1995 indicated that no qualified iodated salt on market was still the main reason that prevented the prevention effect of IDD.
However, the absence of pronounced control effects of most metabolites on the studied enzymes allows us to assign them to a relatively inert pool of metabolites.
Several different types of porous wall/cavity systems are tested to investigate the passive control effects.
The two logics have been tested under various driving conditions to investigate their control effects.
A model is described that allows one to compensate for the influence of perturbing factors and mutual influence of control effects on neighboring regions.
The wind-control effects of shelterbelts with different structures (close-spaced, wider-spaced, and widest-spaced) were investigated by portable wind vane and anemometer, wet and dry bulb thermometer, ground thermometer, glass service instrument.
Controlling effects of forest belts on non-point source pollution of agricultural lands in Taihu Lake area, China
In the present study, we aimed to undertake a statistically high-powered family-based analysis, fully controlling effects of LD between the major DQ-risk haplotypes and neighbouring candidate loci.
Long-term monitoring of wall paintings in historical monuments aims at clarifying involved decay processes and at the same time controlling effects of interventions for conservation.
Number of breeding attempts (i.e., longevity) was the strongest correlate of LRS in all species, after controlling effects of age at first breeding, relative nest initiation date, wing length and body mass.
Dehydroepiandrosterone did not suppress appetite and had no apparent toxic effects at the doses used, and its weight controlling effects were reversible upon withdrawal of treatment.
In order to study the prevention effect of selenium in the development of cardiovascular disease, we investigated the effects of selenium supplementation on the blood rheological properties.
Calcium had a consistent prevention effect on the rate of bone loss in the 12 studies of calcium supplements in postmenopausal women.
From these results, the authors conclude that natural organic germanium has the best prevention effect for intestinal cancer in this animal model (P>amp;lt;0.01), followed by organic germanium (P>amp;lt;0.05).
However, there is no difference in the cancer prevention effect of germanium provided one month before and during dimethylhydrazine treatment, and during dimethylhydrazine treatment only.
CONCLUSIONS: Eight ppm selenium providedviadrinking water has a significant intestinal cancer prevention effect in the presence of a high dose of DMH (20 mg/kg×20 weeks), and the cancer therapeutic effect of selenium is doubtful in this animal model.
