Exude
Definition:
(v. t.) To discharge through pores or incisions, as moisture or other liquid matter; to give out.
(v. i.) To flow from a body through the pores, or by a natural discharge, as juice.

(7) Significant correlations existed between the average number of leukocytes in the gingival exudate and the oral hygiene indices.
(8) These killer cells could lyse a wide range of syngeneic and allogeneic lymphoid tumour cell lines in vitro, and it was found that cell suspensions from nude mice were always significantly more active than those from normal mice, and that the most active effector population was a polymorph-enriched peritoneal-exudate cell suspension.
