Figure 1.

Membrane associated plasminogen activator activity (nmol/min/mg protein) in the whole patient group. Samples were: Start (control sample taken at start of operation); 1 = Res 0; 2 = Rem 0; 3 = Res End; and 4 = Rem End, as described in the Methods. Values are means and the error bars are 95% confidence limits. Student's paired t test analysis showed the Start and Rem End samples to be statistically significantly different (p = 0.01, n = 18). There were no statistical differences between start and any of the other samples.
