1-(2-Methoxy-2-phenyl)-ethyl-4-(2-hydroxy-3-methoxy-3-phenyl)-propyl-iperazine-dihydrochloride (zipeprol, Respilene) is a substance of non-phenanthrenic chemical structure. In the cat, it antagonised cough induced by stimulation of the superior laryngeal nerve or by direct mechanical excitation of the sensitive tracheo-bronchial receptors. The efficacy of zipeprol after enteral administration made it possible both to establish good intestinal absorption and to rank it favourably in relation to several major antitussive reference products; codeine, codethyline, dextromethorphan, diphenhydramine and pentoxyverine. The activity of zipeprol was superior or equal to that of all these substances, excdept codeine. The antitussive properties appeared to be due to a central action. Other properties have been demonstrated which suggest at least a supplementary mechanism in the inhibition of cough, in addition to the central action. These consisted of slight antihistamine and anticholinergic properties, marked local-anesthetic potency and bronchospasmolytic activity. This latter property was demonstrated by the inhibition of histamine and serotonin induced bronchospasm in the guinea-pig. In vitro, using human sputum, zipeprol had a mucolytic action, shown by a decrease in sputum vis viscosity and lysis of DNA and AMPS fibrils. In the dog, at high doses, zipeprol unlike codeine, did not inhibit central stimulation of respiration by hypercapnia, in addition no modification of ventilatory dynamics or blood gases was seen. On the basis of these results, zipeprol can be considered as possessing no respiratory depressant effect even in the upper ranges of its antitussive doses.

A 22-year-old man with T cell type acute lymphoblastic leukemia in first remission underwent autologous bone marrow transplantation (BMT). The preparative regimen included cytosine arabinoside, cyclophosphamide and fractionated total body irradiation. His harvested bone marrow cells were purged with 4-hydroperoxycyclophosphamide. His serological test was positive for cytomegalovirus (CMV) before the BMT. On day 53 after the BMT, he developed dry cough and his chest X-ray film showed bilateral basilar infiltration. Bronchoalveolar lavage was performed and cytology of the specimen revealed typical cytomegaloviral inclusion bodies. DNA analysis and viral culture of the specimen were also positive for CMV. The patient was started on ganciclovir and immunoglobulin with high dose methylprednisolone. His respiratory status deteriorated, however, and the patient expired because of respiratory failure. Autopsy revealed severe interstitial pneumonitis with suppression of CMV replication from the treatment. Interstitial pneumonitis due to CMV should be considered as a significant complication of autologous BMT.

An outbreak of Mycoplasma pneumoniae (MP) infection occurred during the period March-May 1989 among the personnel of the Accident and Emergency Department of the Kuopio University Hospital, Kuopio, Finland. The index patient was a young male orderly, who fell ill with severe pneumonia. His tracheal mucus sample proved to be strongly positive for MP when tested by a commercial DNA-RNA hybridization test (Gen-Probe). After the index patient two additional staff members (an orderly and a nurse) fell ill with pneumonia and 66 others showed symptoms of upper respiratory infection or fever. The most frequent symptoms were a sore throat, a cough, rhinitis and headaches. All 97 employees of the department were tested for the presence of MP in April-May 1989 using throat swabs as test material. Forty-three (44%) were found to be positive for MP by the 'Gen-Probe' test. Eight (19%) of the MP positive staff were completely asymptomatic. The MP positive staff were retested about 3 weeks later, whereupon 40 (93%) had become negative. Most of the persons involved in this outbreak suffered only from mild respiratory symptoms, suggesting that MP outbreaks like the present one may easily pass unnoticed.

A 27-year-old nonsmoking woman complained of cough and chest oppression for two years since an episode of pneumonia. Clinical tests showed decrease in FEV1.0 during attacks of coughing and evidence of bronchial hypersensitivity. While these events fitted the picture of bronchial asthma, the nonwheezing cough suggested cough variant asthma. Antinuclear antibody and anti-ds DNA antibody were increased and leukopenia was recognized, suggesting the diagnosis of systemic lupus erythematosus (SLE). Bronchoalveolar lavage showed lymphocytic alveolitis and decreased T4/T8. These results were suggestive of collagen lung induced by SLE. Inhalation challenge with capsaicin and rapid intravenous injection of lobelin and alinamin indicated that peripheral c-fiber receptors were involved in the induction of coughing. We conclude that the peripheral lesion of collagen lung stimulates the peripheral c-fiber receptors, leading to cough variant asthma.

A 49 years-old man presented with dry cough, low grade fever, and abnormal shadow on a chest X-ray. He had suffered from follicular lymphoma of the liver 5 years previously. He received irradiation therapy in combination with chemotherapy for approximately three years and had been in complete remission. Physical and radiological examination revealed pleural effusion and softly dense masses in the right lung. The laboratory data were within normal limits. He was diagnosed as having lymphomatoid granulomatosis (LYG) by open lung biopsy. The lung lesion was mainly infiltrated with T cells. The patient received prednisolone and the lung lesions disappeared. However, when a lung mass was noted two months later, he started to receive combination chemotherapy consisting of cyclophosphamide, adriamycin, vincristine, and prednisolone every three months. He has not shown relapse of LYG so far. To investigate the association between the preceding follicular lymphoma and subsequent LYG at this time, DNA analysis using the PCR technique was carried out. The LYG lesion did not show a rearranged band for the JH probe, while the paraffin-embedded specimen of the preceding follicular lymphoma had shown rearranged band for the JH band. Southern blot analysis of the LYG lesion, showed no rearrangement for TCR beta, gamma or JH probe. These findings indicate that the LYG was different from the preceding follicular lymphoma in terms of origin. LYG is considered to be induced in the immunosuppressive state due to lymphoma.

DNA probe-assay using the Gen-Probe kit was carried out to detect Mycoplasma pneumoniae infections. Fifteen children visited Ota General Hospital complaining of dry cough and high grade fever. Throat swabs of the patients were examined to detect M. pneumoniae ribosomal RNA by Gen-Prove kit. Five out of 15 patients were positive for DNA probe assay of M. pneumoniae. Clinical and laboratory data including serological examinations were compatible with M. pneumoniae infection in these cases. Following the improvement of clinical symptoms and signs by receiving erythromycin or minocycline, the positivity for DNA probe assay turned to negative. Among the ten patients, who were negative for DNA probe assay, 2 cases were suspected of M. pneumoniae infection on the basis of clinical and laboratory findings. One patient had already taken antibiotics. Therefore, in these two patients, there was a possibility that the bacterial numbers were too small to be detected by DNA-probe assay. The data described above support that DNA-probe assay is useful for the diagnosis of M. pneumoniae infections in the early stage. DNA-probe assay is also valuable to follow up the clinical course of the patients.

A patient with acquired immunodeficiency syndrome (AIDS) was admitted to a hospital with cough and fever and after 29 days was transferred to a hospice. He was eventually shown to have active pulmonary tuberculosis. This diagnosis was obscured clinically by simultaneous infection with Pneumocystis carinii and Mycobacterium avium complex (MAC). Laboratory recognition of Mycobacterium tuberculosis was delayed because of overgrowth of cultures by MAC but was later established using DNA probe techniques. Thirty (19 percent) of 158 health care workers who had been exposed to this patient had conversion of their tuberculin skin tests. Diagnostic difficulties and nosocomial transmission of tuberculosis may occur when patients with AIDS have mixed mycobacterial infections.

To understand better the events associated with the initiation of lung disease in young children with cystic fibrosis (CF), we prospectively performed a longitudinal study examining the early bacteriologic, immunologic, and clinical courses of 42 children with CF diagnosed after identification by neonatal screening. Serial evaluations included history and physical examination, chest radiographs, throat cultures for bacteria, and determinations of serum immunoglobulin levels and circulating immune complexes. At a mean follow-up age of 27 months, 19% of the children had serial throat cultures positive for Pseudomonas aeruginosa; the first positive culture was found at a mean age of 21 months. In three infants the initial P. aeruginosa isolates were mucoid. As determined by typing with a DNA probe, serial P. aeruginosa isolates from each patient were identical over time but were genetically distinct from isolates recovered from other patients. Of 11 infants with P. aeruginosa, nine (82%) had previous isolates of Staphylococcus aureus or Haemophilus influenzae; all had received prior antibiotic therapy. In comparison with other infants with CF, children with P. aeruginosa grown on serial throat cultures more frequently had daily cough (p less than 0.01), lower chest radiograph scores (p less than 0.05), and elevated levels of circulating immune complexes (p less than 0.01). None of the study infants had persistent hypogammaglobulinemia or hypergammaglobulinemia. We conclude that (1) S. aureus and H. influenzae remain the isolates most frequently recovered from infants with CF; (2) initial recovery of P. aeruginosa by throat culture is often preceded by the onset of chronic respiratory signs; (3) elevations of circulating immune complexes can occur early, often after the initial recovery of P. aeruginosa; and (4) early P. aeruginosa isolates are genetically distinct, demonstrating the lack of cross-colonization in this newborn population.

This paper proposes that the mammalian immune response known as "allergy" evolved as a last line of defense against the extensive array of toxic substances that exist in the environment in the form of secondary plant compounds and venoms. Whereas nonimmunological defenses typically can target only classes of toxins, the immune system is uniquely capable of the fine-tuning required to target selectively the specific molecular configurations of individual toxins. Toxic substances are commonly allergenic. The pharmacological chemicals released by the body's mast cells during an IgE antibody-mediated allergic response typically cause vomiting diarrhea, coughing, tearing, sneezing, or scratching, which help to expel from the body the toxic substance that triggered the response; individuals frequently develop aversions to substances that have triggered such responses. A strong allergic response often includes a decrease in blood pressure, which slows the rate at which toxins circulate to target organs. The immune system identifies as toxic the following kinds of substances: (1) those low-molecular-weight substances that bind covalently to serum proteins (e.g., many plant toxins); (2) nontoxic proteins that act as carriers of toxins with low molecular weights (e.g., plant proteins associated with plant toxins); (3) specific substances of high molecular weight that harmed individuals in ancestral mammalian populations for a span of time that was significant from the standpoint of natural selection (e.g., the toxic proteins of bee venom. Substances that bind covalently to serum proteins generally are acutely toxic, and because many of these substances also bind covalently to the DNA of target cells, they are potentially mutagenic and carcinogenic as well. Thus, by protecting against acute toxicity, allergy may also defend against mutagens and carcinogens. The toxic hypothesis explains the main phenomena of allergy; why IgE-mediated allergies usually occur within minutes of exposure to an allergen and why they are often so severe; why the manifestations of allergy include vomiting, diarrhea, coughing, sneezing, scratching, tearing, and a drop in blood pressure; why covalent binding of low-molecular-weight substances to serum proteins frequently causes allergy; why allergies occur to many foods, pollens, venoms, metals, and drugs; why allergic cross-reactivity occurs to foods and pollen from unrelated botanical families; why allergy appears to be so capricious and variable; and why allergy is more prevalent in industrial societies than it is in foraging societies. This hypothesis also has implications for the diagnosis, prevention, and treatment of allergy.

Five sheep with ovine pulmonary carcinoma were markedly dyspneic and had sporadic coughing; two had copious watery nasal exudate. In four, lesions consisted of multifocal nodules of neoplastic cuboidal epithelial cells in acinar or papillary patterns. Electron microscopically, cells had microvilli, tight junctions, and cytoplasmic lamellar bodies typical of alveolar type II cells. One sheep had a single lung tumor of nonciliated bronchiolar epithelial cells. Vacuolated alveolar macrophages surrounded adenomatous foci. One sheep had a metastatic lesion in the caudal mediastinal lymph node. All sheep had histologic lesions of lymphoid interstitial pneumonia (LIP, ovine progressive pneumonia) consisting of peribronchiolar and interstitial lymphoid hyperplasia, and fibromuscular proliferation; all had serum precipitating antibodies to ovine lentivirus. Lung fluids or tumor homogenates contained a 26-kd peptide that crossreacted with a primate-derived type D retrovirus as detected by immunoblotting or interspecies competition radioimmunoassay. Ovine lentivirus was isolated from concentrated lung fluids or tumor tissues of four sheep tested and from tumor cell DNA of one animal transfected into ovine muscle cells. These studies document the presence of type D-related retrovirus antigen in ovine pulmonary carcinoma (OPC) in the United States and indicate that lentivirus-induced LIP is a lesion frequently associated with this disease.
