Solenopsis invicta is a kind of invasive pest that causes serious damage to local agriculture, environment, and human health. They attack mainly with venom within stingers. Those who are allergic to the venom would suffer a systemic anaphylaxis, even fatal shock, after being stinged by these ants. Many studies reveal that their venom is mainly composed by water, insoluble alkaloids and trace proteins, within which alkaloids are the main cause of burning sensation and blisters, while allergic reactions are caused by proteins or peptides. The research progress of toxic substances in the venom of Solenopsis invicta as well as the roles and functions of each component were reviewed in this paper.

Objective:To analyse the rifampiein-induced renal insufficiency for clinical reference.Methods:The data of 32 cases were collected and reviewed from the national journals of 1991-1998.Results:Rifampicin-in duced renal insufficiency related to the drug taken in the past and the hypersensitive constitution,yet it was in no relation with the dosage and discontinuous duration of the drug.Conclusion:Rifampicim would be cautiously tried for patients in clinical practice.The patient with allergic history should not take it;he should stop the drug immediately when allergic signs appeared at the early stage of administration.
