A study of the health of 78 workers in an iron and steel foundry in Vancouver, British Columbia, was carried out and the results compared with those found in 372 railway repair yard workers who were not significantly exposed to air contaminants at work. The foundry workers were exposed to PepSet, which consists of diphenyl methane diisocyanate (MDI) and phenol formaldehyde and their decomposition products as well as to silica containing particulates. A questionnaire was administered by trained interviewers, and chest radiography, allergy skin tests, pulmonary function tests, and methacholine inhalation tests were carried out as well as measurement levels of dust and MDI. Compared with the controls, the foundry workers had more respiratory symptoms and a significantly lower mean FEV1 and FEF25-75% after adjustments had been made for differences in age, height, and smoking habit. Three workers (4.8%) had radiographic evidence of pneumoconiosis and 12 (18.2%) had asthma defined as presence of bronchial hyperreactivity, cough, and additional respiratory symptoms such as wheeze, chest tightness, or breathlessness. Sensitisation to MDI is probably the cause of asthma in these workers.

The effectiveness and the safety of a new chemotherapeutic phenol derivative, clofoctol, was evaluated in adult hospitalized patients affected by infectious diseases of the bronchopulmonary tract. The clinical diagnosis included acute exacerbation of chronic bronchitis, acute bronchitis, bronchiectasis, pneumonia, bronchopneumonia and lung cavitary neoplasm. Expectoration, cough, dyspnoea, respiratory murmur and body temperature were considered as clinical factors to which an arbitrary score was given. Functional respiratory parameters including FVC, FEV1 and FEV1/FVC X 100 were also evaluated. All the patients were treated rectally with clofoctol 1500 mg daily for five days. Bacterial evidence of infection was obtained by sputum culture, which was repeated at the end of treatment. At that time, bacteriological results were 72.4% disappearance of baseline pathogens, 20.7% persistence of baseline pathogens and 6.9% presence of different organisms. Functional respiratory parameters were found to be significantly improved by treatment. Clinical results, arbitrarily evaluated on the basis of the overall assessment of laboratory and functional data, were excellent in 33.3%, good in 44.4%, fair in 5.6% and poor in 16.7% of patients. Tolerance was generally good; side-effects included maculopapular rash in 2 patients and rectal disturbances in 10 patients. In conclusion, for the treatment of bronchopulmonary diseases clofoctol offers an interesting alternative to antibiotic therapy.

The use of di-isopropyl phenol (Diprivan) for induction of anaesthesia was assessed in doses ranging from 1 to 3 mg kg-1. With less than 1.75mg kg-1 not all patients were anaesthetized; 2.0 mg kg-1 appeared to be a satisfactory induction dose. Involuntary muscle movement, cough and hiccup at induction were rare with any dose studied. However, the frequency of hypotension and respiratory depression were related to the dose given. Pain on injection was uncommon when the drug was given into an antecubital vein, but occurred in 39% of patients when injected to the back of the hand or wrist. Recovery was rapid, and characterized by lack of emetic sequelae. Di-isopropyl phenol 1.5 - 2.0 mg kg-1 given rapidly during reactive hyperaemia can produce anaesthesia in one arm-brain circulation time. A reaction involving flush, hypotension, cough, laryngospasm and bronchospasm occurred in one patient receiving 2.5 mg kg-1 given over 20 s.

A five year retrospective review of all exposures to a high concentration phenol disinfectant (Creolin Disinfectant 26% phenol) reported to a regional poison center located 96 cases, with 16 cases lost to follow up. There were 60 oral-only exposures, 7 dermal-only exposures and 12 oral/dermal exposure. One patient was an inhalation exposure. Fifty-two cases (65%) were evaluated in a hospital. Eleven patients with oral exposures (14%) experienced rapid CNS depression, but no seizures occurred. Vomiting, coughing, and stridor was noted in 14, 7 and 4 patients respectively. Burns were noted in 17 of 72 (24%) patients with oral exposure and 5 of 19 (26%) with dermal exposure. Seventeen patients underwent endoscopy. Tissue sloughing was noted in one case. All other burns were first degree. No cardiovascular complications occurred. Twenty-eight patients (35%) were followed at home via telephone with one episode of vomiting and one episode of dermal irritation occurring. CNS toxicity from exposure to a high concentration phenol containing cleaning product appears to be rapid in onset. The absence of serious toxicity and major chemical burns in this series does not eliminate concern with the corrosive and systemic risks of phenol poisoning.

OBJECTIVE: To evaluate the pharmacological effects of Liangyuan Pipagao on cough reflex and ciliary action. Liangyuan Pipagao is a compound preparation of traditional Chinese medicine. METHODS: Cough was induced by aerosol citric acid in guinea pigs and aerosol capsacin in mice. Excretion function of the airway in mice was determined by phenol red method. Ciliary movement function of frog esophagus was examined by a migration method of charcoal granules. RESULTS: Liangyuan Pipagao inhibited both the citric acid-induced cough in guinea pigs and capsacin-induced cough in mice. ID(50)value 2.64 g/kg (95%Cl1.12 approximately 6.19) and 11.40 g/kg (95%Cl5.76 approximately 22.58) respectively. Further, Liangyuan Pipagao increased phenol red excretion in mice airways and stimulated ciliary action of frog esophagusin a dose-dependent fashion. ED(50) value 7.70 g/kg (95%Cl 4.62 approximately 12.83) and EC(25) value 1.07 X 10(-4) (95% Cl 0.394 approximately 2.92x10(-4)) respectively. CONCLUSION: Liangyuan Pipagao a traditional Chinese medicine may have anti-tussive as well as expectorant actions.

A rural town in western New York was the site of a release of a mixture of 2-chloro-6-fluorophenol (CFP), toluene and water due to a pressure build-up at a nearby chemical facility. The regional poison control center received calls from physician offices and individual patients describing symptoms felt related to this exposure. Symptoms included headache, dry throat, cough, chest discomfort, nausea/vomiting, and diarrhea. Environmental sampling by the state health department confirmed soil and surface contamination; however, despite a noticeable odor during sampling, staff did not detect CFP in air samples. To our knowledge, although many individuals visited their primary care providers, none were hospitalized. This incident suggests that acute exposure to CFP is similar to other phenol exposures with relatively minor symptoms including headache, irritation of mucous membranes, and gastrointestinal symptoms.

The leaf of Elaeagnus pungens thunb. (Family Elaeagnaceae) has been documented as an effective herb for the treatment of asthma and chronic bronchitis in traditional Chinese medicine. This study was aimed at evaluating the anti-asthmatic, antitussive and expectorant activities in vivo of the ethanolic extract and fractions from the leaf of Elaeagnus pungens. The results showed that the 70% ethanolic extract increased the preconvulsive time of asthma induced by the combination of histamine and acetylcholine chloride in guinea pigs at the medium dose of 1.379 g/kg. The water fraction significantly prolonged the preconvulsive time (P<0.05) in guinea pigs, lengthened the latent period of cough (P<0.05) as well as decreased the cough frequency caused by citric acid in guinea pigs (P<0.01) and enhanced tracheal phenol red output in mice (P<0.01). Moreover, the petroleum ether fraction significantly reduced the cough frequency induced in guinea pigs (P<0.01) and improved tracheal phenol red output in mice (P<0.01). It indicated that the petroleum ether fraction and the water fraction of Elaeagnus pungens leaf were effective on anti-asthmatic, antitussive and expectorant activities, which supplied for further research on chemical constituents and pharmacological mechanisms.

The primary objective of this study is to evaluate the antitussive, expectorant and anti-inflammatory effects of alkaloids imperialine (I), chuanbeinone (II), verticinone (III), and verticine (IV), which were isolated from the Bulbus Fritillariae Cirrhosae (BFC) using phytochemical method. The results showed that all the alkaloids significantly inhibited cough frequency and increased latent period of cough in mice induced by ammonia. Besides, imperialine(I), verticinone(III) and verticine(IV) markedly enhanced mice's tracheal phenol red output in expectorant evaluation, and imperialine(I), chuanbeinone(II) significantly inhibited the development of ear edema in a dose-dependent manner in anti-inflammatory assessment. Moreover, important differences were found among the structure-activity relationships for the four alkaloids. These results confirmed that the four alkaloids imperialine, chuanbeinone, verticinone and verticine may be the active ingredients of the Bulbus F. Cirrhosae (BFC).

Different parts of Acacia nilotica (L.) Delile, Calotropis procera (Aiton) W.T. Aiton, Adhatoda vasica Nees, Fagoniaar abica L. and Casuarina equisetifolia L. are traditionally used in folk medicine for the treatment of a variety of common ailments like nausea, cold, cough, asthma, fevers, diarrhea, sore throat, swelling, etc. The present study was aimed to evaluate the anti-Helicobacter pylori and urease inhibition activities of extracts produced from the above selected medicinal plants native to Soon Valley (home to an old civilization) in the Punjab province of Pakistan. Methanol, acetone and water extracts of the plants were evaluated for anti-bacterial activity against thirty four clinical isolates and two reference strains of H. pylori. Minimum inhibitory concentrations (MICs) of the extracts were determined using the agar dilution method and compared with some standard antibiotics like amoxicillin (AMX), clarithromycin (CLA), tetracycline (TET) and metronidazole (MNZ), used in the triple therapy for H. pylori eradication. H. pylori urease inhibition activity of the extracts was assessed by the phenol red method, wherein, Lineweaver-Burk plots were used to determine Michaelis-Menten constants for elucidating the mechanism of inhibition. Methanol and acetone extracts from Acacia nilotica and Calotropis procera exhibited stronger anti-H. pylori activity than MNZ, almost comparable activity with TET, but were found to be less potent than AMX and CLT. The rest of the extracts exhibited lower activity than the standard antibiotics used in this study. In the H. pylori urease inhibitory assay, methanol and acetone extracts of Acacia nilotica and Calotropis procera showed significant inhibition. Lineweaver-Burk plots indicated a competitive mechanism for extract of Acacia nilotica, whereas extract of Calotropis procera exhibited a mixed type of inhibition.
