  1. Liver tissue was fixed immediately after perfusion. Morphometric analysis was performed by electronmicroscopy at a magnification of × 40?000 according to Weibel et al23 and Weibel.24 For experimental details, see also Methods.7 Results are given as mean±s.d. of 4–5 tissue samples in arbitrary units of volume or area, (each single data point represents a mean of six measurements per tissue sample).
  2. *P<0.05 vs control, unpaired two-tailed Student's t-test.
