A STUDY OF PGE AND PGF_(2a) RELEASING CAPACITY OF ALVEOLAR MACRO PHAGES IN ASTHMATICS / 解放军医学杂志

Bronchoalveolar lavage (BAL) was performed in healthy subjects (n = 12) and patients with bronchial asthma (n = ll). Between two groups there were no significant differences in total cells and percentage of alveolar macrophages (AM), lymphocytes, ncutrophils, cosinophils in BAL fluids. When AM were cultured in vitro and stimulated with dermatophagoides farinae(DPF) antigen, the quantity of PGE released by AM was significantly increased in asthmatics. When asthmatics' AM were sensitized with specific IgE positive serum and stimulated with DPF, they released more PGE, PGF2a than that when specific IgE negative serum was used (P
