Squirrel monkeys were inoculated by the intratracheal inoculation of 700 Klebsiella pneumoniae organisms and developed lobar pneumonia in about 24 h. Characteristic clinical findings were fever, anorexia, and coughing. Laboratory findings included leukocytosis or leukopenia (with the latter more prominent in ultimately fatal infections), bacteremia, and shedding of bacteria into the pharynx. Infected monkeys showed increased plasma lysozyme activity as well as increased plasma ceruloplasmin, haptoglobin and alpha1-antitrypsin. The mortality rate was 60%, and the mean time of death was 50.5 h. Pathologically, the disease spread by means of Kohn's pores and other pathways that generally did not involve airways as a means of dissemination until about 30 h. Squirrel monkeys seem to be better models for human respiratory K. pneumoniae infection than rats or mice.

In a controlled clinical trial Frubienzym (throat lozenges with 5 mg lysozyme, 2 mg papaine and 200 I.U. bacitracin) or placebo have been given to 100 patients with pharyngitis and/or tonsillitis for 4 days. Under treatment with Frubienzym reddening, swelling, matter and mucus in the throat, coughing, swelling and pain of lymphatic ganglions and pain of swallowing vanished more quickly than under placebo. The differences were significant (p less than 0,05, p less than 0,001 or even p less than 0,001; U-test of Wilcoxon, Man and Whitney). There were no side effects which could be attributed to Frubienzym.

A 39-year-old male was admitted complaining of nonproductive cough and dyspnea on exertion. Death occurred eight months after onset of the symptoms. Autopsy examination showed that the pulmonary trunk and left main pulmonary artery were markedly dilated and completely occluded by a tumor. The tumor had infiltrated into the left upper lobe and mediastinal lymph nodes, and metastatic nodules were found in both lungs and in the left adrenal gland. Small foci of infarction were noted in the lower lobes of both lungs. The tumor cells were of two types; pleomorphic spindle cells and bizarre multinucleated giant cells. Immunohistochemically, they were positive for vimentin, myosin, and lysozyme, but negative for desmin and muscle-specific actin. The cytoplasm of the tumor cells was showed by electron microscopy to contain microfilaments, dense bodies, and pinocytotic vesicles. We diagnosed this case as undifferentiated sarcoma of the pulmonary artery. Approximately 100 cases of pulmonary artery sarcoma have been reported. Histopathologically, almost all of the reported cases showed both spindle cells and pleomorphic giant cells, indicating a biologically anaplastic neoplasm.

Normally the daily volume of lower respiratory tract secretions, in man, is probably less than 100 ml. In hypersecretory disease the volume increases sufficiently to cause cough and expectoration of secretions as sputum. The proportions which are sol or gel vary in disease as does the way in which constituent molecules partition in each phase. The constituent molecules and the cells which produce them (indicated in parentheses) may be classified as follows: 1. Mucus-glycoproteins present as droplets, or sheets (produced by mucous cells), periciliary fluid (serous or ciliated cell or a transudate), surface muco-substance (all epithelial cells) or surfactant hypophase (Clara or type II alveolar cells). 2. Proteins and peptides such as lysozyme (serous cell and macrophage), lactoferrin (serous cell and neutrophil), secretory piece (surface epithelium and submucosal glands), regulatory neuropeptides (dense-core granulated cell and both motor and sensory nerves) and fibronectin (alveolar macrophages). 3. Glycosaminoglycans such as heparan sulphate (epithelial membranes), heparin (mast cell), chondroitin sulphates and hyaluronate (connective tissue constituents). 4. Lipids including triglycerides (stored in cells) glycolipids (cell membrane), phospholipids (type II alveolar cells), sphingolipids (cell membrane), steroids (? Clara cells) and terpenes (cell membrane). 5. Anti-proteases and anti-oxidants such as bronchial protease inhibitors (serous anc Clara cells), alpha-2-macroglobulin (macrophage), alpha-1-antitrypsin (transudate) and anti-oxidants (type II alveolar cell and macrophage). 6. Other 'secretions' including ions and water (surface epithelium and submucosal glands), mediators of inflammation (migratory cell granules and their membranes), and serum proteins (present in transudate/exudate).

Antimicrobial effect of lysozyme in combination with a wide set of antimicrobial drugs (38) was studied with respect to 74 bacterial cultures. It was shown that synergism of the antimicrobial effect in the presence of lysozyme was variable for drugs differing in the mechanism of their action and depended on the pathogen species. The most pronounced synergistic effect was observed with respect to grampositive bacteria with the use of many drugs such as benzylpenicillin, ampiox, morphocycline, erythromycin and others. The potentiation effect of lysozyme was less pronounced with respect to Coli bacteria and Pseudomonas. Combination of lysozyme with aminoglycosides such as gentamicin, tobramycin, sisomicin and amikacin resulted in increasing antimicrobial effect with respect to practically all the microbial cultures tested. The clinical trials of the efficient combinations of the antibiotics and lysozyme studied experimentally proved their high efficacy in combined therapy of patients with pneumonia and pyelonephritis of bacterial genesis. Thus, in children with acute pneumonia (92 observations) it resulted in more rapid elimination of the temperature reaction, toxic and cardiorespiratiry syndromes, cough and physical signs of the disease. In treatment of 83 children with pyelonephritis complete clinico-laboratory remission was observed in 81 per cent of the cases against 56.4 per cent in the patients treated with the antibiotics without lysozyme.

Physiologic, morphologic, biochemical, and immunologic methods have been used to study cholinergic and adrenergic regulation of airway submucosal gland secretion. Using a newly developed micropipette method, we can now measure the rate of fluid flow from each individual gland duct and we can harvest these secretions for specific chemical analysis. Stimulation of both the cholinergic and adrenergic systems affect gland secretions. The vagus nerves are the pathways for many reflexes affecting secretion: laryngeal, gastric and carotid body chemoreceptor stimulation accelerate the fluid production, and lung inflation (Hering-Breuer reflex) inhibits fluid secretion. Stimulation by cholinergic, muscarinic agonists depletes both mucous and serous cells, so vagal reflexes probably produce mixed secretions. In contrast, alpha-adrenergic agonists deplete serous cell contents, release high concentrations of lysozyme and produce large volumes of fluid with a low protein concentration, while beta-adrenergic stimulation may selectively deplete mucous cells, releases little lysozyme and produces scanty fluid with a high protein concentration. The significance of this cholinergic and adrenergic modulation on cough and ciliary clearance are important subjects for future study.

A 60-year-old woman was admitted to our hospital because of progressive cough and chest pain for 2 months. She also complained of exertional dyspnea. Bilateral diffuse infiltlative shadows were found on the chest roentogenogram. Ground-glass opacity in the middle lobe and lingula, and subpleural patchy consolidation were seen on the computed tomogram of the chest. Arterial oxygenation and diffusing capacity were low. The level of angiotensin-converting enzyme in serum was normal, but that of lysozyme was high. In the BAL (broncho-alveolar lavage) fluid, total cell count and the number of lymphocytes were high, and the CD 4/8 ratio of the lymphocytes was high. Open lung biopsy revealed numerous confluent sarcoid granulomas with necrosis, which strongly correlated with severe vasculitis. After necrotizing sarcoid granulomatosis was diagnosed, prednisolone was administered, which resulted in improvement of symptoms and disappearance of chest-radiograph shadows. Necrotizing sarcoid granulomatosis may be seen as a variant type of sarcoidosis. However, clinical findings including the chest-radiograph shadows and clinical course of this case differ from those of ordinary sarcoidosis. These clinical findings can be attributed to severe vasculitis, as revealed by histological examination.

Forty-seven patients with pulmonary sarcoidosis stage II-III, fulfilling clinical indications for starting treatment with corticosteroids, received oral methylprednisolone for 8 weeks in gradually decreasing doses (starting dose 48 mg per day). From week 5 onwards, they also received inhaled budesonide, 1.6 mg daily. Treatment was continued for 18 months and all patients have been followed for at least 3 years. At 18 months treatment could be discontinued in 38 patients, who had used individually adjusted doses of budesonide depending on the clinical response (reduced doses in 14, initial dose in 16, and increased doses in 8 patients). Budesonide treatment alone was satisfactory in 31 of these 38 cases. An additional seven patients could stop treatment after receiving supplementary courses of oral steroids for 3-12 months. Treatment is ongoing in 9 patients in which 6 have extrapulmonary manifestations requiring oral steroids. The chest radiograph became normal in 22 patients and improved in 14. Significant improvements were noted in FVC and DLco in relation to predicted normal values. Serum ACE, lysozyme and beta 2-microglobulin values decreased significantly. Transient cough was seen in 5 and hoarseness in 3 patients. No systemic side-effects were noted; one patient taking 2.4 mg budesonide daily had a plasma cortisol value below the normal range. Inhaled budesonide seems to offer an effective and safe alternative to oral steroids for long-term maintenance treatment of patients with pulmonary sarcoidosis.

We describe a rare case of pulmonary sarcoidosis with multiple cavitation and pneumothorax. A 32-year-old woman was admitted to our hospital with a dry cough and an interstitial shadow with dense infiltrates in both upper lungs and cavitation in the right upper lung on chest roentgenogram and CT. Laboratory tests revealed an elevated level of serum lysozyme. BAL fluid demonstrated a high proportion of lymphocytes with an increased CD4/CD8 ratio, compatible with sarcoidosis. Transbronchial lung and skin biopsies showed evidence of noncaseating epithelioid-cell granuloma, and a diagnosis of sarcoidosis was made. Although pneumothorax appeared in the left lung on chest roentgenogram during clinical observation conservative treatment without corticosteroids or any other therapy for a follow-up period of 3 years resulted in improvement of her clinical condition and abnormal X-ray findings.

An overlap of breast-feeding and late pregnancy is associated with decreased intake of human milk and reduced infant growth. We evaluated the association of an overlap with macronutrient and immunological components of milk, infant urinary IgA, and infant and maternal morbidity. On d 2 and 1 mo postpartum, staff measured 24-h intake of breast milk and collected samples from 133 Peruvian women; 68 had breast-fed during the last trimester of pregnancy (BFP) and 65 had not breast-fed during pregnancy (NBFP). Data on maternal and infant anthropometry and health were collected for 1 mo. On d 2, lactose and lysozyme concentrations were higher, total lysozyme intake was higher and concentration and total intake of lactoferrin were lower in the BFP than the NBFP group (P < 0.05). The total 1-mo IgA intake was lower among BFP than NBFP infants (P = 0.01). Urinary IgA concentration was correlated with breast milk IgA concentration (r = 0.29; P = 0.01) but not with breast-feeding during pregnancy. An overlap was not associated with diarrhea but BFP infants were 5 times as likely to have a cough for at least 7 d than NBFP infants (P < 0.05). Reported mastitis was rare and occurred only in the NBFP group (P = 0.05). An overlap of breast-feeding and late pregnancy was associated with changes in milk composition, an increased frequency in symptoms of infant respiratory illness but decreased reported mastitis. Further in-depth studies are warranted to determine the cumulative effects associated with a breast-feeding/pregnancy overlap on infant and maternal outcomes.
