Effect of antirat TNFα and antirat IL-4 antisera on subacute (4-hour) Ang-II-induced leukocyte responses within rat mesenteric postcapillary venules. These responses were measured in the same rats as those described in the legend to Figure 3: venular responses of leukocyte rolling flux (A), leukocyte rolling velocity (B), leukocyte adhesion (C), and leukocyte emigration (D) are mean (± SEM). *P < .05 or **P < .01 relative to the PBS group.
