title: Rheological studies of matrix--special reference on the mobility of leucocytes in relation to the rheological characters of experimental matrix.
abstract: The rheological characteristics of a model matrix, consisting of Bacto-agar, were correlated with the ability of the matrix to permit cellular penetration, using a rheolometer and the agar bullet method. The most important rheologic characteristic that affected cellular mobility was found to be the viscosity rate. A viscosity rate under 1,000 X 10(4) dyne sec/cm2 was needed to permit cellular mobility.
