Silicone induces differential recruitment of leukocytes. Rat peritoneal cells (n = 4/group) were obtained after 45 days, 48 h and 24 h of the i.p. injection of 1 ml of silicone. Differential cell counting was assessed by microscopic observation of cytospin preparations stained with Giemsa. Standard errors of the means are depicted. A representative of three experiment performed is shown.a p < 0.05, b p < 0.01 and c p < 0.001 vs. Normal. Mann Whitney U-test, and Student-Neuman-Keuls post test comparisons were used in these experiments.
