The GC pictures were taken to investigate the difference of Samul-tang and Sakunja-tang from their distillate each. For Samul-tang, it's distillate contained many peaks which had been shown very small peaks in the GC picture of the original solution, but the one pick(rt about 7 min.) of the picture didn't been found in the GC picture of the distillate. For Sakunja-tang, it's distillate contained all peaks which had shown in the GC picture of the original solution. After distillation, there was almost no peak in the rest of the solution.

This study examined the effect of pine needle distillate (Pinus densiflora Sieb. et Zucc) on the immune system and hematological parameters. C57BL/6 male mice weighing 20 ~21 g were divided into 3 groups and intraperitonially injected with either 200 $\mu$L of saline (control), 50% diluted (P50) or 100% pine needle distillate (P100) once a day for 24 days. At the end of the experiment, the mice were anesthetized by ether and peripheral blood was collected from the femoral artery and the spleen was excised. Spleen weight decreased significantly (p<0.001) in the pine needle groups compared to the control group. The blood was used for a complete blood count and flow cytometrical analysis after immunofluorescence staining. The pine needle distillate dose-dependently decreased the CD4$^{＋}$/CD8 sup ＋/ ratio (p <0.05), and showed a tendency to increase the mean FSC (forward scatter) values of the CD8$^{＋}$T cells, while decrease the values of the CD4$^{＋}$T cells. There were no significant differences in WBC, RBC and platelet counts among the three groups, but hemoglobin and hemoglobin-related parameters and platelet volume increased and red blood cell volumes decreased with the administration of the pine needle distillate. These results suggest that the pine needle distillate may have immunosuppressive effects.

Middle distillate was produced by the hydrocracking of F-T wax on the zeolite catalysts. Novel metal loaded zeolite catalysts had good performance for hydrocracking of F-T wax. 2 wt.% Platinum loaded H-Y zeolite catalyst showed the highest selectivity of middle distillate and conversion of F-T wax. H-Y zeolite had more strong acidity site and large pore than that of another zeolite catalyst. So, H-Y zeolilte catalyst showed the best activity for hydrocracking of F-T wax.

Dual-fuel engines are being researched with emphasis on the possible types of natural gas supply systems. Hence, a three-dimensional combustion model by using finite volume method was developed to provide a fundamental understanding of the auto-ignition of pilot distillate and subsequent burning of natural gas, when the natural gas as well as the distillate was directly injected into a quiescent diesel engine like combustion bomb tests and the numerical results were investigated for the mixed combustion phenomena. With high-pressure natural gas injection, it was found that the gaseous fuel injection characteristics had to be well harmonised with that of the pilot distillate. For better combustion efficiency, however, further researches are required for the optimisation of injection system in the existence of air motion.

1. Objectives: The purpose of this study is to investigate the effect of Suhwagije-tang(SGT) distillate on the immune activity of spleen cells of aged SD rats. 2. Methods: We used 10, 50, 72 weeks old SD rats in this study. Spleen cells from SD rats were stimulated with ConA and treated with 1% Vitamin C(Vit.C) or Suhwagijetang distillate(SGT). After 24 hours, the concentrations of IL-2, IL-4, IL-10, IFN-${\gamma}$ in the cell culture supernatant were measured by ELISA. 3. Results and Conclusions 1) At all concentration of SGT distillate, survival rates of liver cells were higher than the control group. In addition, 50% SGT distillate group's cell survival rates were significantly higher than other groups. 2) In 10 weeks SD rats(SGT group), the concentration of IL-2 significantly decreased in comparison with ConA group, Vit.C group. In 52 weeks SD rats(SGT group), the concentration of IL-2 significantly decreased in comparison with ConA group. 3) In 10, 52 weeks SD rats(SGT group), the concentration of IL-4 significantly decreased in comparison with ConA group. 4) In 10 weeks SD rats(SGT group), the concentration of IL-10 significantly decreased in comparison with ConA group. And in 72 weeks SD rats(SGT group), the concentration of IL-10 significantly increased in comparison with Vit.C group. 5) In 52, 72 weeks SD rats(SGT group), the concentration of IFN-${\gamma}$ significantly decreased in comparison with 10 weeks SD rats(SGT group). These results suggest that Suhwagije-tang(SGT) distillate has the effect of increasing the immune activity of spleen cells of aged SD rats.

The deodorizing responses of the steam distillate from some medicinal plants(G-3) on three representative malodors were evaluated by estimating the best estimate threshold(BET) of odor responses. With a single spray of G-3, the BETs of malodors such as ammonia, acetic acid, and ethyl acetate were found to increase 4.11, 32.6 and 13.1 fold, respectively, which indicated G-3 possessed a potent deodorizing activity. The deodorizing potency of G-3 was also demonstrated to be as high as and even higher than those of the commercial deodorizing agents.
