[Effective endmembers based bilinear unmixing model].

An effective endmembers based bilinear unmixing algorithm is prompted in the present paper together with an end-member subset selection algorithm as well. Firstly, the endmembers are ranked according to their distance to the mixed pixel, involving the Euclidean distance and spectral angle. And then, an effective subset of the endmembers is abstracted considering both the ranking result and the change of error.

Immunotherapy using IL-2 and GM-CSF is a potential treatment for multidrug-resistant Mycobacterium tuberculosis.

This study investigated the therapeutic effects of interleukin (IL)-2 and granulocyte-macrophage colony-stimulating factor (GM-CSF) co-administrated with antibacterial agents isoniazid (INH) and rifampin (RIF) to treat a mouse model of tuberculosis (TB) infection. A drug-susceptible TB strain, H37Rv was used to infect mice and the effectiveness of IL-2 and GM-CSF was initially evaluated based on survival rate, bacterial counts in lungs and spleens and the pathological condition of the lungs. Next, the therapeutic effect of the immunotherapy regimen was assessed in multidrug-resistant strain OB35-infected mice.

[The survey of 21 cases of human rabies in Anlong county in Guizhou province].

Objective: To analyze 21 cases of rabies from February 8 to May 1 in 2004 in Anlong county in Guizhou province, and to explore the possible factors causing the epidemics.

Methods: 21 cases of rabies were investigated. The canine brains were collected, and indirect immunofluorescence assay was used to detect rabies virus antigen in the brains.
