Myelin sheath immunostaining in different group.

<p>MPP immunostaining of pancreatic cancer tissue in the euglycemia group (A, B, arrowhead) and hyperglycemia group (C, D, arrowhead). The left panel shows an original magnification of 100×, and the right panel an original magnification of 400×. The frequency of moderate to strong MPP staining of nerves was significantly lower in the hyperglycemia group than in the euglycemia group. Figure arrowheads indicate the immunostainings.
