Comparison of mucus flow rate, radiolabelled glycoprotein output and smooth muscle contraction in the ferret XXXX in vitro.

@entity825 @entity3045 @entity2710 @entity2647
1. The concentration-response curves for rate of mucus output, labelled-glycoprotein output and smooth muscle contraction in response to @entity2710 , @entity2647 and @entity3045 were determined in the ferret @entity825 in vitro. 2. The potencies of @entity2710 and @entity2647 are both in order: smooth muscle contraction, glycoprotein output, rate of mucus output. 3. At lower concentrations @entity2710 is more potent than is @entity2647 on smooth muscle contraction, glycoprotein output and rate of mucus output. 4. Concentration-response curves for @entity3045 show very little change in rate of mucus output but a large increase in glycoprotein output. 5. It is concluded that the glycoprotein output induced by @entity3045 may come from a source different from those induced by @entity2710 and @entity2647 .
