Alpha adrenergic stimulating drugs, metaraminol, norepinephrine, phenylephrine, was found to increase, in vitro, immunological phagocytosis by mice peritoneal macrophages. This effect could be inhibited by dibenamine, a blocking agent. The stimulation by alpha adrenergic agents was similar to that caused by drugs that reduce the intracellular levels of(More)
It was shown that adrenergic drugs, which increase the intracellular levels of cAMP, inhibit the rosette formation by T-lymphocytes, but stimulate the rosettes produced by B-lymphocytes. Cholinergic drugs, which increase the levels of cGMP, on the contrary, stimulate the formation of rosettes by T-lymphocytes but inhibit those produced by B-lymphocytes.
