Glomerular involvement characterized by mesangial cell proliferation with fibrillar thickening of the axial region and deposits of immune complexes is reported in three human cases of kala-azar. IgG was seen in all 3 and Igm in 2 patients. Complement (C3) was detected in the glomeruli in all cases and fibrinogen in the only case in which it was tested for.(More)
This work investigated the potential use of an alternative adsorbent to anti-immunoglobulin E (IgE)-agarose for IgE selective adsorption therapy. A screening of several commercially available adsorbents (Concanavalin A, Lens culinaris[Lc], d-tryptophan, poly-l-lysine, and aminohexyl immobilized on agarose) was done through batch system assays, considering(More)
This work investigated the adsorption of autoantibodies such as anti-SS-A/Ro, anti-SS-B/La, anti-Sm, and anti-dsDNA on protein L-agarose gel. In order to determine better conditions for IgG adsorption on this matrix, some buffer systems were tested. Adsorption data were analyzed using the Langmuir and Langmuir-Freundlich isotherm models. The experimental(More)
To examine previous work carried out at a single center, i.e., France, on the pathologic features of chronic pancreatitis and to examine geographic differences, 359 cases of chronic pancreatitis from five centers were studied pathologically and the results analyzed according to appropriate statistical methods. It was found that it was easy to separate(More)
