Figure 3.
Gelatinase zymogram from right ventricular tissue isolated from animals on day 1 and week 6 after vehicle treatment or at the indicated times after PE. The right panel shows a separate experiment determining gelatinase activity on day 1 after PE and day 1 after PE in animals treated with anti-PMN antibody to reduce neutrophil influx into RV tissue. Extracts from 8 to 10 hearts were pooled for each group. Density absorbance values are graphed for each of the major bands of activity.
