Title: Immunological methods of determining c-hepatis antibodies employing antigens containing conformative epithopes
Inventor: CHIEN DAVID Y
IPC: G01N33/569
Filed: 1993-07-02
Abstract: Immunoassay methods utilizing HCV envelope antigens that contain conformational epitopes reactive with antibodies in serum from infected individuals are useful for screening and diagnosis. These antigens detect antibodies that are not detected by denatured HCV envelope antigens. In addition, these HCV envelope antigens comprised of conformational epitopes are more immunologically reactive than a number of other HCV antigens. This is the first evidence that conformational epitopes may be involved in the immunologic response to HCV antigens.

Effects of Bifidobacterium strains on dextran sodium sulfate (DDS) induced colitis in rat was tested. Sprague dawley rates were administered orally with different strains of Bifidobacterium for 7 days prior to the induction of colitis (day 0) and were continuously administered for 7 days in combination with DDS (5% w/v dissolved in water). The degree of colitis were determined daily with disease activity index (DAI). Sampling was performed on day 14 and bacterial translocation and quantity in the intestine was determined. DAI was significantly lower in the group receiving B.infantis CURE 19 compared to the groups receiving Lactobacillus paracasei 8700:2 and L.gasseri LG1. After 6 and 7 days, orally administered bacterial strains were able to exercise positive effects by decreasing translocation on experimental colitis in rats. CURE 19 was more effective in counteracting the colitis than the others.
