Serum amylase level was determined in 129 cases (225 episodes) of chronic respiratory failure at acute exacerbation and in 59 cases (62 episodes) of pneumonia without respiratory failure as control. Cases with accompanying diseases, such as acute pancreatitis, parotiditis, ileus and renal dysfunction, which were expected to develop hyperamylasemia were excluded. The 225 episodes were divided according to the causes of acute exacerbation into 4 groups: pneumonia, bronchitis, right heart failure without infection, and others (e. g. hemoptysis). Hyperamylasemia (greater than 400 S-U) was observed in groups of pneumonia (15/40 = 35.5%) and bronchitis (12/95 = 12.6%), respectively but not in those of right heart failure without infection (0/73 = 0%) and other causes (0/17 = 0%). As a result, hyperamylasemia was found only under conditions of inflammation of lung parenchyma and bronchi with acute exacerbation of respiratory failure. On the other hand no hyperamylasemia was observed in 62 episodes of pneumonia alone without respiratory failure. It was concluded that both respiratory tract infection and acute respiratory failure are necessary factors for development of hyperamylasemia originating from lung or bronchi.

Vasoactive intestinal peptide (VIP), which is localized in normal human lung, may play an important role in regulating bronchial tone, pulmonary blood flow and mucus secretion. The level of plasma VIP and bronchial responsiveness were studied in patients with asthma, chronic bronchitis and the healthy subjects. The results showed that the level of plasma VIP in asthmatic patients during acute attack and symptom-free period was significantly lower than that in the patients with bronchitis and the healthy subjects and it is negatively correlated with the bronchial hyperresponsiveness. It is suggested that both asthmatic attack and bronchial tone are related with the decrease of VIP.

A prospective study for C. pneumoniae infection was conducted in 134 patients with acute respiratory disease and 134 matched patients with other medical reasons from January to May 1994 in Beijing. The positive rate of micro-IF (MIF) IgG antibodies was 93% (125/134) and 89% (119/134) respectively (0.1 < P < 0.25) and the geometric mean titers (GMT) were not found to be significant (55.9 +/- 4.2 vs 41.7 +/- 2.8, 0.1 < P < 0.20). Ten patients, four (4/30) with pneumonia and six (6/81) with bronchitis were serologically diagnosed as having recent C. pneumoniae infection. Chronic bronchitis was statistically more frequent in patients with C. pneumoniae infection than those without (0.025 < P < 0.05). Patients with chronic bronchitis (GMT, 87.1 +/- 3.9; n = 36) tended to have higher IgG titers than those without (GMT, 47.6 +/- 4.1; n = 98, 0.02 < P < 0.05). Culture of retro-pharyngeal swab specimens for C. pneumoniae was negative in the all 134 studied patients.
