Abstract:
Objective: To prepare the processing solution of realgar by bacteria and to explore the change of pharmacodynamic action and toxicity. Methods: The processing solutions of realgar were prepared using the strain thiobacillus ferroxidans, the realgar powder processed by normal method was selected as control. The effects on RPMI8226 cell proliferation of them were investigated by methyl thiazolyl terazolium (MTT),cell cycle distribution was determined by FCM in RPMI8226 cell. The distribution of arsenic concentration in blood and tissues including heart, liver, spleen, lung, and kidney in the samples were determined by Inductively Coupled Plasma-atomic Emission Spectrometry (ICP-AES). Results: Compared with control group, the solubility rate and the induced apoptotic rate increased, and dosage significantly reduced, while arsenic was hardly found in the tissue in processing group by bacteria. Conclusions: The processing group by bacteria may be enhanced medicinal efficacy and inhibited the toxicity in realgar. It’s intending to provide new approaches for scientific processing realgar.
