In all zooplanktons, the site-occurrence-rates of Copepoda and Chaetognatha were the highest, 100% and 93.3%, and the average biomass of which were 298.56 mg·m-3 and 118.09 mg·m-3 and the summation accounted for 96.88% of total biomass. The result shows that these two species created a strong relationship with the distribution of saury fishing grounds, and their biomass can be considered as the important indicator of looking for the main saury fishing grounds.

Rare elements and REE are mainly enriched in gray-black trachyte and less in other rocks. In addition, schistosity, pyritization, silicification and carbonation in gray-black trachyte are contributed to enrich rare element and REE.

In order to inquire the causes of occurrence of lipoid pneumonia in rat that were raised in standard SPF animal reproductive area, we used self-reproducing standard SPF rats, male 50 and female 50. All of the rats were divided into 10 groups, raised in standard Barrier system, and fed the standard diets imported from U.S.A.. All animals were divided into 4 stages to sacrifice. Autopsy, histopathological and blood biochemical examination were made at each stage. The results reveal that no lipoid pneumonia were found to occur in the 5, 10 and 26-week-old groups of male and female rats. 40% of male and 60% of female were found to occur slight focal lipoid pneumonia in the 52-week-old groups of rats.
