    Notes: Abstract We describe experimental results on the extensional viscosity of mobile polymer solutions obtained from two instruments, the first being a commercial Spin Line Rheometer and the second a custom-built lubricated-die Converging Flow Rheometer. The interpretation of data in terms of Trouton ratios is facilitated by a simple analysis for the Generalized Newtonian Fluid model. Agreement between data from the two rheometers is satisfactory and we show that polymer solutions can be either tension stiffening or tension thinning. However, the Trouton ratios in both cases are greater than the Newtonian values and we anticipate that this will always be the case for polymer solutions.

    Mechanism of irritant-induced cough: Studies with a kinin antagonist and a kallikrein inhibitor (1996)
    Springer
    Lung 174 (1996), S. 269-275 
    Details
    ISSN: 1432-1750
    Keywords: Cough ; Bradykinin ; Kallikrein

    Topics: Medicine
    Notes: Abstract It has been suggested that bradykinin may play a role in stimulating cough in at least one pathological condition in humans. We have employed an animal model to investigate the possible role of this peptide in irritant-induced cough. The kinin antagonist Hoe 140 and codeine both produced dose-related inhibition of cough responses to inhalation of citric acid or bradykinin aerosols by conscious guinea pigs. The selective tissue kallikrein inhibitor CH694 inhibited cough caused by citric acid but not by bradykinin. Indomethacin pretreatment attenuated the responses to both stimuli as did phosphoramidon. It is concluded that cough produced by citric acid inhalation may be mediated, at least in part, by generation of kinins; secondary to this, a release of prostanoids also appears to participate in the response.
