In this study, it was attempted to understand the effect of crude drug on biotransformation of drugs. Cimicifuga Rhizoma, Glycyrrhizae·Radix, Bupleuri Radix are popular among the crude drugs that has been use widely in the traditional medicine. These crude drugs were extracted by water and were studied on the blood level of salicylate in rat after aspirin adminstration. Cimicifuga Rhizoma extract (g/kg) which was given a single dose, significantly increased salicylate blood level. On the contratry, Glycyrrhizae Radix extract (200mg/kg) decreased blood level of salicylate after aspirin adminstration in rat pretreated with the crude drugs for 4 days. Bupleuri Radix extract (300mg/kg) has not effected on salicylate blood level after aspirin administration in rat.

Recent focus on wastewater treatment includes energy-saving and renewable energy generation for energy-independence of water infrastructures. Aeration and pumping in biological wastewater removal processes account for nearly 30-60% of the total electricity cost in real wastewater treatment plants. In this study, the performance and microbial characteristics were investigated in sequencing batch reactor under typical oxygen and oxygen limited condition. Under typical DO (7.55±0.99 mg/L) and low DO (0.23±0.08 mg/L) conditions, COD removal was stable over 91 % during SBR operation. Ammonia removal efficiency was reduced from 95.6 % to 89.2 % when DO concentration was dropped sharply. Phosphorus removal efficiency also reached 77% at oxygen-limited condition. The results indicated that removal efficiency both ammonia and phosphorus was influenced by DO condition. Microbial analysis revealed that Proteobacteria and Bacteroidetes at phylum level was dominant in typical DO and low DO conditions and DO concentration did not much affect phylum distribution. Population decrease of genera of nitrifying bacteria(Dokdonella) and Dechloromonas spp. affect removal efficiency of nitrogen and phosphorus at low DO condition.
