[Effect of heavy metal lead on anticoagulant activity of leech based on label-free quantitative proteomics].

Whitmania pigra is the most widely distributed species of leeches in the market. In this study, the effect of heavy metal lead pollution on the anticoagulant activity of Wh. pigra was studied and the potential mechanism was explored.

[Effect of lead pollution on anticoagulant effect of Whitmania pigra based on in vitro anticoagulation experiment].

Leech has a good anticoagulant activity and is one of the raw materials for treatment of many cardiovascular and cerebrovascular diseases. This study was based on in vitro anticoagulant experiments( APTT and PT) to investigate the effects of lead contamination on the anticoagulant effect of leech. At present,the Hirudo circulating in the market are dominated by Whitmania pigra,therefore Wh.

[Diversity of fungi on surface of Pheretima].

Traditional Chinese medicines( TCMs) are easily contaminated by fungi during planting,harvesting,processing,transportation and storage. The 2015 version of Chinese Pharmacopoeia stipulates the detection of aflatoxin in Dilong. After reviewing the literature,it has been found that there are no domestic and foreign scholars who have studied the surface fungi of Dilong.
