Analysis of the Contractile Effect of the Ethodin-Degranulated Fraction of Mast Cells: Influence of the Number of Mast Cells Added to the Culture
| Number of mast cells | Length of smooth muscle cells | |
|---|---|---|
| Without ethodin | With ethodin (10 μmol/l) | |
| μm | ||
| 8,000 mast cells/ml | 46.42 ± 27.50 (195) | 45.88 ± 22.30 (175) |
| 16,000 mast cells/ml | 44.86 ± 28.20 (186) | 44.47 ± 29.40 (145) |
| 32,000 mast cells/ml | 43.05 ± 29.30 (175) | 40.46 ± 29.70 (144) |
| 64,000 mast cells/ml | 46.55 ± 27.20 (161) | 37.88 ± 24.80 (203)1-a |
Results are expressed as the mean cell length ± S.D. The number in parentheses indicates the number of cells photographed and analyzed in each case.
↵1-a P < .01 compared with the respective control without ethodin.
