title: Effects of cyclamate calcium on the immune response in rabbits.
abstract: To determine the effect of cyclamate calcium on the humoral immune response in rabbits, one group was fed a 3% and another a 5% water solution of cyclamate calcium. A third group served as controls. After 150 days, the animals were tested for their ability to respond immunologically to bovine serum albumin (BSA). Other aspects of immunity investigated were the presence or absence of neoplasia of the urinary bladder, spleen, thymus, and lymph nodes, the number of white and red blood cells, and cyclamate conversion and excretion in the urine. The results indicated that the 5% group had a delayed and suppressed response to BSA. No neoplasia was detected. This group had fewer red cells and excreted increased concentrations of cyclohexylamine in the urine.
