Effects of wrapping with PDLLA on hepatic and renal functions, which were assessed with an Olympus® AU640 clinical chemistry analyzer: alanine aminotransferase (A; ALT) aspartate aminotransferase (B; AST), total protein (C; TP), albumin/globulin ratio (D; A/G), creatinine (E; Cr), and urea nitrogen (F; BUN). Group 1 represents direct suturing only after sciatic nerve transection. Group 2 represents wrapping with artificial nerve conduits after sciatic nerve transection and anastomosis. Group 3 represents wrapping with PDLLA film after sciatic nerve transection and anastomosis.
