Some factors affecting single chamber direct microbial fuel cell performance such as iron concentration in the cathode electrode,substrates in anode chamber,substrate concentration and anode electrode area were studied with a single chamber direct microbial fuel cell.

Under the selected experimental condition, the average removal ratio of COD_(cr) could reach more than 85% and the biological concentration could also reach 28.

AIM To establish a simple and practical method for the estimation of the inter-patient variability of cytochrome P450(CYP3A)enzyme activity and to predict drug concentration and parmacokinetics of etoposide with the variability of CYP3A in chidren patients with leukemia.

Objective: To establish a HPLC method for the determination of the drug concentration in bile after the injection of lomefloxacine.

It was found that SM2 was absorbed quickly and distributed widely, the concentrations in the tissues of heart, liver, lung, kidney and small intestine were all higher,facially, the drug concentration in the tissue of small intestine was highest.
