Figure 4. Levels of arginase I and II mRNAs in lungs of control and silica-treated rats.

Figure 4

Rats were intratracheally instilled with either 1 or 5 mg silica/100 g BW or an equivalent volume of vehicle. After 24 hr, total mRNA was isolated from rat lungs as described in Materials and Methods. Levels of arginase I (filled bars) and arginase II (open bars) mRNAs (mean ± SE; n = 5–8) are expressed relative to the levels in saline-treated lungs. *p<0.05.
