We investigated interstitial pneumonia, one of the most severe postoperative acute complications of respiratory surgery. In sixteen years, from 1982 through 1997, 2,453 cases underwent thoracotomies caused by lung cancers, in our institute. There were 20 cases (0.79%) who died within 30 days after surgery (operative death). Six out of 20 cases died of interstitial pneumonia, one of the most frequent postoperative complications. We examined these six patients and 2 patients with postoperative interstitial pneumonia who died within 32 days. Preoperative lung function tests, laboratory data, chest CT and/or chest X-ray films cannot predict development of postoperative interstitial pneumonia. Those who acquired postoperative interstitial pneumonia had continuous high fever after surgery following reticular shadows on their chest X-ray and increase in LDH levels. We could not detect any characteristic viral infections. Although, they were treated by steroid, elastase inhibitor and/or immune suppressant, they died within 32 days. In conclusion, development of postoperative of interstitial pneumonia cannot be predicted from preoperative laboratory data and/or lung function tests.

A novel elastase inhibitor from Aspergillus nidulans NBRC 4340, Asnidin, was isolated, and biochemical properties and partial amino acid sequence were examined. Column chromatography using diethylaminoethyl (DE) 52-Cellulose and reversed-phase HPLC were used to purify the inhibitor. Purified Asnidin was found to be homogeneous as indicated by reversed-phase HPLC and TOF-MS (Time of Flight Mass Spectrometry). Asnidin has a molecular weight of 4,181.63 as determined by TOF-MS. The elastolytic activities of elastases from A. fumigatus, A. flavus, and human leukocytes but not chymotrypsin, and elastases from snake venom and bacteria were inhibited by Asnidin. The fibrinogenase and collagen type IV hydrolytic activities of the elastase from A. fumigatus were inhibited by Asnidin. Asnidin was found to be stable under heat treatment and over a wide pH range. The elastolytic inhibitory activity of Asnidin was inhibited by dithiothreitol (DTT), while no inhibition was observed with ethylenediaminetetraacetic acid (EDTA-2Na) and benzamidine. Since there is a possibility of Asnidin becoming another drug in the arsenal of weapons against aspergillosis or interstitial pneumonia, further studies are warranted.
