when hp-mc were cultured for 1 wk with the fibroblasts and were then incubated for 5 min with a 1/20 dilution of rabbit anti-rat ige , they generated and released an average of 22 +/- 10 ng ( mean +/- sd , n = 5 ) of prostaglandin d2 per 10 ( 6 ) cells and exocytosed a higher net percentage of their total histamine content ( 44 +/- 11 % [ mean +/- sd , n = 8 ] ) than did cells just isolated from the animal ( 6 +/- 4 % [ mean +/- sd , n = 4 ] ) .
