This cross-sectional survey was conducted as Phase I of the Prairie Ecosystem Study (PECOS): Environmental Pesticide Exposure and Human Health. In November of 1995, community volunteers delivered a self-administered household questionnaire to 1185 rural households in southern Saskatchewan, Canada. The survey provided a broad description of the general health and the physical environment of 511 men, 499 women, and 393 children (< 18 years of age) residing in 549 respondent households in the rural study area (population density of about one person/km2). Families in the respondent households resided on a farm, in town or both. Of the 369 households that operated a farm, 25.2% of the households did not list the farm as their primary household. Residents of both farming and non-farming households reported contact with pesticides and fertilizers through home or garden use. History of smoking was greater among men and women from non-farming households. The most commonly reported health problems among the children were a history of bronchitis, asthma, skin allergies, pneumonia, and hay fever. The most frequently reported health problems among the men were a history of high blood pressure, bronchitis, pneumonia, hearing problems, and stress; and among the women were a history of bronchitis, high blood pressure, shortness of breath, and pneumonia. Compared to farming households, more members of non-farming households reported a history of respiratory problems, particularly bronchitis among the women and children. Overall, there were important differences in the smoking history, the occupational use of pesticides and fertilizers, and the general health status between the farming and non-farming households and individuals in this rural population.

Renin-angiotensin system (RAS) and hemodynamics in pulmonary artery (PA) were assessed in 25 patients with chronic non-obstructive bronchitis and 73 patients with chronic obstructive pulmonary diseases (COPD). RAS in COPD patients was activated. The degree of this activation rose with progression of respiratory failure. Hypertension in PA was secondary to RAS activation. The data were obtained on the essential role of RAS in the onset and progression of pulmonary hypertension. This allows to design new approaches to pathogenetic treatment of secondary pulmonary hypertension.

We studied exposures to higher daily maximum temperatures and concentrations of air pollutants in Tokyo during the summer months of July and August from 1980 to 1995 and their effects on hospital emergency transports for cardiovascular and respiratory diseases for males and females > 65 years of age. Cardiovascular diseases were angina, cardiac insufficiency, hypertension, and myocardial infarction. Respiratory diseases were asthma, acute and chronic bronchitis, and pneumonia. Except for pneumonia, daily maximum temperatures were not associated with hospital emergency transports. Increasing daily maximum temperatures, however, were associated with decreased hospital emergency transports for hypertension. Concentrations of nitrogen dioxide or particulate matter < or = 10 microm, however, were associated with daily hospital emergency transports for angina, cardiac insufficiency, myocardial infarction, asthma, acute and chronic bronchitis, and pneumonia. For cardiac insufficiency, hypertension, myocardial infarction, asthma, chronic bronchitis, and pneumonia, the expected daily number of emergency transports per million were greater for males than for females. For angina and acute bronchitis, there were no differences for the expected daily numbers of emergency transports per million between males and females.

The herb, Chrysanthemum zawadskii var, latilobum commomly known as Gu-Jul-Cho in Korea, used in traditional medicine to treat pneumonia, bronchitis, cough, common cold, pharyngitis, bladder-related disorders, gastroenteric disorders, and hypertension. Linarin is the main active compound and the biological mechanisms of its activity are unclear. It is believed that effects of this herb may be exerted through the pluripotent effectors of linarin due to its ability to treat a variety of afflictions. In this study, the effects of linarin on the mouse macrophages cell line, RAW 264.7, were investigated. It was found that linarin could activate macrophages by producing cytokines. Monocytes and tissue macrophages produce at least two groups of protein mediators of inflammation, interleukin 1 (IL-1) and the tumor necrosis factor (TNF). Recent studies have shown that TNF and IL-1 modulate the inflammatory function of endothelial cells, leukocytes, and fibroblasts. TNF-alpha production by macrophages treated with linarin occured in a dose dependent manner. However, IL-1 production was largely unaffected by this natural product. This study demonstrated the ability of linarin to activate macrophages both directly and indirectly. Linarin also affect both cytokine production and nitric oxide inhibition, in addition to the expression of some surface molecules. Nitric oxide (NO), derived from L-argin-ine, is produced by two forms(constitutive and inducible) of nitric oxide synthase (NOS). The NO produced in large amounts by inducible NOS is known to be responsible for the vasodilation and hypotension observed in septic shock. Linarin was found to inhibit NO production in the LPS-activated RAW 264.7 cells. Linarin may be a useful candidate as a new drug for treating endotoxemia and the inflammation accompanied by NO overproduction. The linarin-treated total lymphocytes exhibited cytotoxicity in a dose dependent manner between 20 microg/ml and 40 microg/ml. These results suggest that linarin may function through macrophage activation.

Studies covered incidence of coronary heart disease, its risk factors and features of constitutional types among Kouzbass coal miners suffering from anthracosilicosis and chronic dust bronchitis. Findings are reliably higher incidence of coronary heart disease among coal miners having lung diseases caused by dust. Coronary heart disease among the miners with anthracosilicosis is favored by arterial hypertension, overweight and hypersthenic constitutional type, that among those with dust bronchitis is favored only by overweight.

Safety, tolerability and antihypertensive efficacy of a cardioselective beta-blocker nebivolol was studied in 30 patients with mild and moderate hypertension and concomitant stage I chronic obstructive bronchitis. Nebivolol (5 mg/day) was given for 1 month; in 5 patients complementary hydrochlorothiazide (12.5 mg/day) was required for sufficient antihypertensive effect. Nebivolol was well tolerated (only 1 patient complained of head ache), did not cause worsening of bronchitis and spirometric parameters, exerted no cardiodepressive action, and did not induce apparent disturbances of metabolism.

The widely accepted notion that certain individuals are more susceptible to air pollutants than others has been revitalized by recent epidemiology that strongly suggests that the elderly, particularly those with underlying cardiopulmonary diseases (e.g. chronic obstructive pulmonary disease (COPD), infection), and children with asthma are more susceptible to the adverse outcomes associated with ambient particulate matter (PM). Pulmonary toxicologists have adopted 'susceptibility' as an issue that can be approached experimentally and have begun to develop as well as study more relevant animal models. These models may have specific genetic traits or cardiopulmonary impairments analogous to human diseases. The goal is to identify potential susceptibility characteristics and elucidate whether responsiveness is due to impair compensation or some unique mechanisms. Several rodent models have been used with PM: pulmonary vasculitis, bronchitis, COPD, allergic asthma, infectious lung diseases, systemic hypertension, and congestive heart disease. Transgenic and knockout mice are of growing interest but have seen limited use in air pollutants studies, with primary interest being directed to specific mechanistic questions. No model should be used without careful consideration of its strengths and limitations. However, when interpreted in the context of field and epidemiology findings, they may reveal generic susceptibility attributes or useful biomarkers.

The study of morbidity in general medicine is very useful in order to adapt training curricula to the reality of medical practice in the first degree. The objective of this work was to describe the morbidity charted in general medicine in Tunisia's Sousse region. It consisted of a prospective and descriptive study involving six basic health centres in Sousse and was conducted over the course of 30 randomly selected days during the year 2000. There were 4022 consultations included in the study which were described according to the SOAP plan. The coding of the charted diagnoses was carried out according to the International Classification of Primary Care (CISP). There were 98% of the consultants who were self-referred and 84% of the consultations corresponded to new cases. The consultants' sex-ratio was 0.5 in favour of females with an average age of 27 years. There were 4,597 diagnoses noted utilising 336 codes from the CISP classification system. The "Respiratory" chapter took the first place on the list (39.6%) followed by the "Circulatory" chapter. The "Top 30" list of the most often charted diagnoses totaled 72% of the consultations among which the three most frequent health problems were pharyngitis (14.4%), acute bronchitis (8.3%) and arterial hypertension (7.4%). This study demonstrates that the practice of general medicine is characterised by instinctive first solutions and versatility. The predominance of cardiovascular and respiratory illnesses illustrates the double burden of morbidity which is faced by Tunisian general medicine practitioners. The "Top 30" list should serve as basis for planning pregraduate and continuing medical training.

Nineteen patients with chronic obstructive disease of the lungs and 15 patients with chronic non-obstructive bronchitis of the dust etiology were examined for the purpose of investigating the rheological blood properties and of their interrelation with pulmonary hypertension. The hemorheological properties were evaluated by spontaneous aggregation of erythrocytes and thrombocytes. The control group comprised 8 healthy subjects. The results denoted that the rheological blood properties are to a great extent impaired in patients with dust bronchitis. The rheological blood properties worsened as hypertension of the small blood-circulation circle was increasing; it preceded the development of pulmonary hypertension in patients with chronic obstructive disease of the lungs. The aggregation changes appear to be primarily related with the functional state of thrombocytes in patients with chronic non-obstructive bronchitis; a concurrently higher aggregation of thrombocytes and erythrocytes was observed in patients with chronic obstructive disease of the lungs. The obtained data can be useful for designing a medicamental correction scheme of rheological impairments as a trend within the treatment of affected hemodynamics in the small blood-circulation circle in patients with duct bronchitis.

Alcohol as a semi-luxury item is socially accepted in our society and its usage constitutes a normative behaviour. The transition from consumption to abuse is often rapid. Results supply evidence for widely spread alcohol addictions in Germany. The following paper examines the consumption and the abuse of alcohol using the data from the Interdisciplinary Longitudinal Study of Adulthood (ILSE). The findings of a questionnaire investigating diet and medical examination data [interview data referring to alcohol consumption and laboratory findings concerning Gamma-Glutamyl-Transferase levels (Gamma-GT-levels)] based on two cohorts (years of birth 1930-1932 and 1950-1952) from centres of investigation in Heidelberg and Leipzig are adopted in this study. The centre comparison indicates higher alcohol consumption in the Leipziger study participants. The findings register less alcohol usage at the second measurement point, where as the Gamma-GT-levels rise and a greater endangering of health can, therefore, be noted. Besides alcohol, cigarettes are a widely accepted everyday drug in Germany. The health risks are enormous (e. g. high blood pressure, bronchitis and lung cancer). The smoking habits of the two cohorts will be described at two measurement points concerning participants from Heidelberg and Leipzig. The cohort comparison demonstrates a significant disadvantage of the younger women, although, as for as, the men are concerned no clear difference can be found.
