results: the lowest concentrations of nzvi that inhibited the visible growth (mic) of e. amylovora, x. oryzae, b. cereus and streptomyces spp. were 625, 550, 1250 and 1280 ppm, respectively. the minimum bactericidal concentration (mbc) for e. amylovora and x. oryzae were 10,000 and 5,000 ppm of nzvi, respectively. mbc was not observed for the gram positive bacteria. no bacteriostatic and bacter...

Aas, K. (1970). Archives of Disease in Childhood, 45, 221. Bronchial provocation tests in asthma. Bronchial provocation tests are necessary for precise aetiological diagnosis in bronchial asthma. This is illustrated by the results in 9,364 bronchial provocation tests compared with skin tests and nasal tests. The technique of bronchial provocation testing and its interpretation are described in ...

the link between allergic rhinitis and asthma is well known. bronchial hyperreactivity (bhr) may be present in rhinitis. the present study was aimed to compare airway responses in patients  with rhinitis symptoms alone following exercise challenge, and to  determine relationship of two different respiratory function tests. 98 subjects with rhinitis were investigated by spirometry and impulse os...

It is difficult to analyse the relationship between bronchial responsiveness and the severity of asthma since each alone is difficult to assess. Asthma is a heterogeneous condition with many patterns of expression, and clinical methods used to assess its severity have their limitations. Problems also arise in interpreting the results of bronchial provocation tests and methodological differences...

The reproducibility of the output of seven different nebulisers was tested. Nebulisers with a minimal increase in output at higher flow rates had less variability in the output. The selection of a nebuliser for bronchial provocation tests depends on the intranebuliser variability. Two nebulisers had highly reproducible outputs.

Occupational asthma due to platinum salts is a frequent disease in platinum refineries. The diagnosis is based upon a history of work related symptoms and a positive skin prick test with platinum salts. Bronchial provocation tests have not been performed in epidemiological studies because the skin test is believed to be highly specific and sensitive. As no reliable data about this issue current...
