Histologic study to compare a novel and conventional preservation of isolated lungs. The lung tissue from each patient with lung cancer (ie, cases 1 to 3) was suspended in Euro-Collins solution and was kept at 4°C or at −5°C for 5 days. Thereafter the tissue was fixed and stained. Representative results of three cases is shown. (A–C) The tissue was stored at 4°C. (D–F) The tissue stored at −5°C were stained with hematoxylin-eosin (HE; left panel) and with anti-single-stranded DNA (ssDNA) antibody (right panel, brown-colored). The lung tissue stored at 4°C showed degenerative changes in (A) the alveoli, (B) the bronchi, and (C) the blood vessels. The bronchial epithelium (arrows) was severely affected (inserted square). In contrast, the tissues stored at −5°C, including (D) the alveoli, (E) the bronchi, and (F) the blood vessels were well preserved (inserted square). (A–C) Single-stranded DNA was frequently found in tissues stored at 4°C, but (D–F) was almost absent in tissues stored at −5°C. Original magnification ×200 except for insets (×400).

Cysteinyl-leukotriene synthesis in chopped lung fragments caused by anaphylactic reaction. Lung tissue removed from two patients (cases 4 and 5) was suspended in Euro-Collins solution and kept at −5°C (hatched column) or 4°C (black column) for 3 days. Thereafter the lung fragments were cut into small pieces with scissors and then incubated with human immunoglobulin E at 22°C for 15 hours for passive sensitization. After washing with Tyrode’s buffer, the passively sensitized lung fragments were stimulated with or without anti-human immunoglobulin-E antibody (7.75 μg/nL) at 37°C for 30 minutes in the presence or absence of the patients’ serum (n = 4). After the termination of the reaction, cysLTs in the supernatants were assayed by purification with column chromatography and enzyme immunoassay. Data are reported as the mean ± standard error of the mean. The statistical analysis was performed using analysis of variance, and the Tukey-Kramer test was used for multiple comparisons (*p < 0.05). (αIgE ab = anti-immunoglobulin E-antibody.)
