Perivascular fibrosis was also assessed using a Masson trichrome stain. Compared to normal rats, 4 weeks of uremia produced significant areas of perivascular fibrosis well as increased vessel thickness in the myocardium from these rats. Treatment with paricalcitol, from the onset of uremia, markedly reduced the development of perivascular fibrosis and the increase in the vessel thickness.
