Effects of AH 6809 on the inhibitory actions of PGD2 on anti-IgE induced histamine release from rat peritoneal mast cells. Ibuprofen (10−5 M) treated mast cells were exposed to anti-IgE and PGD2 together with AH 6809. Spontaneous release of histamine was 13.9±1.1% whereas anti-IgE induced histamine release was 31.9±3.3%. Results are given as means±s.e.mean for n=4.
