Mast cells in autonomic ganglia and nerves and in small blood vessels in the renal hilus of domestic swine
2008
Vodenicharov, A.
After toluidine blue staining and polychromatic staining mast cells were observed in autonomic ganglia and nerves on histological and semithin cross sections as well as in the wall of small vessels located in the renal hilus around the renal artery and vein and their first branches. The light maicroscopy revealed that mast cells were situated among the pseudounipolar nerve cells of ganglia inside the autonomic fibres and their perineurium. In small blood vessels mast cells were located in the wall of arterioles and small arteries and near the wall of venules and small veins. Mast cells were also observed in the connective and adipose tissues of the renal hilus. The data of the present study allowed us to suggest that mast cells were involved in the function of mentioned structures via the biologically active substances secreted by them.
