title: Effect of bovine horn cancer serum on E-rosetting capacity of peripheral blood lymphocytes from normal unaffected animals.
abstract: The effect of serum from horn cancer affected bullocks and cows on E-rosetting capacity of peripheral blood lymphocytes (PBL) from unaffected control animals was examined. The E-rosette counts were made using 2-aminoethyl isothiouronium bromide (AET) treated sheep red blood cells. A significant decrease in the percentage of EAET rosette forming cells was noticed when PBL were incubated with 50 per cent serum from animals affected with horn cancer. However, no such effect was noticed when PBL were treated with 50 per cent serum from unaffected control animals. A linear relationship was observed between percentage of EAET rosette forming cells of animals affected with horn cancer and E-rosette inhibitory activity of the corresponding serum on PBL from control animals.
