Characteristic Viscoelastic Parameters for Amorphous Polymers

By use of a reference value of modulus equal to 109 dynes/cm2 and a reference value of time equal to 10 sec, characteristic viscoelastic parameters are defined from stress relaxation master curves and from modulus-temperature curves. Values of these parameters are tabulated for several linear amorphous polymers and slightly crosslinked amorphous polymers.

Potassium iodide inhibits neutrophil chemotaxis

We studied the effect of potassium iodide on the chemotaxis of neutrophil in 15 healthy subjects with a modified Boyden chamber method. Orally administered potassium iodide (15 mg/kg/day for 3 days) significantly inhibited the neutrophil chemotaxis in peripheral blood. It is postulated that the therapeutic effect of potassium iodide on erythema nodosum, nodular vasculitis, and Sweet's syndrome might be mediated through the inhibition of neutrophil chemotaxis by this agent.
