Tolerability and patient acceptance of sodium phosphate tablets compared with 4-L PEG solution in colon cleansing: combined results of 2 identically designed, randomized, controlled, parallel group, multicenter phase 3 trials.

Goals: Evaluate patient tolerance and acceptance of a sodium phosphate (NaP) tablet purgative compared with a 4-L polyethylene glycol (PEG) solution.

Background: Characteristics and side effects of bowel purgatives deter patients from undergoing screening colonoscopy. Published data demonstrated comparable bowel cleansing with NaP tablets and a 4-L PEG solution in 2 phase for 3 studies.

Bovine milk IgG, but not serum IgG, inhibits pokeweed mitogen-induced antibody secretion by human peripheral blood mononuclear cells.

Bovine milk IgG markedly inhibits the pokeweed mitogen (PWM)-induced secretion of immunoglobulins from human peripheral blood mononuclear cells. Heat-aggregated bovine milk IgG is even more inhibitory, demonstrating significant inhibition when levels as low as 5-9 micrograms/ml are continuously present in the in vitro 14-day culture system. However, bovine serum IgG, regardless of its state of aggregation, and control proteins have little effect on PWM-induced secretion of human IgG, IgA, and IgM.
