Abstract A Cryoprotein was separated from periodontitis patients sera and characterized as a cryoglobulin. The cryocrit percentages were ranged from 1–8% in patients as compared to 1–3% in controls. The cryoglobulin concentration were ranged from 90–240 mg/L with mean value of 188 mg/L as compared to 1.3–4 mg/L. Immunofixation studies have shown secondary mixed cryoglobulinemia of IgA-IgG-IgM type. The assessment of herd immunity using cryoglobulin as a probe revealed that there are three main fraction as: low, moderate and high responders. The herd immunity plats were normal and skewed respectively. Top Keywords Cryoglobulin, Cryocrit, Herd Immunity, Immunofixation. Top |
