Whereas, the average human eosinophil MBP (±) SEM in patients’ sera with mild-moderate AD (n = 97), severe AD (n = 33), mild-moderate persistent AR (n = 83), severe persistent AR (n = 37), mild-moderate persistent BA (n = 93) and severe persistent BA (n = 52) was 9.60 ± 1.96, 14.34 ± 1.21, 11.47 ± 0.81, 17.31 ± 1.31, 7.41 ± 0.62 and 10.31 ± 0.82 ng/ml, respectively (Fig. 4b). The gene discussed is MBP; the disease is breast angiosarcoma.
