Application of a Low-Level Laser Therapy and the Purified Protein from Natural Latex (Hevea brasiliensis) in the Controlled Crush Injury of the Sciatic Nerve of Rats: A Morphological, Quantitative, and Ultrastructural Study
Figure 2
Light microscopy morphology—(a) CG—4 weeks—normal bundles of nerve fibers (*) and blood capillaries (arrows) (mag: ×10, bar: 100 μm). (b) EG—4 weeks—bundles of nerve fibers (*), blood capillaries (arrows), and the perineurium area (thin arrows) (mag: ×10, bar: 100 μm). (c) IG—4 weeks—spaces (arrowheads) among nerve fibers (*) containing an amorphous substance and blood capillaries (arrow) (mag: ×10, bar: 100 μm). (d) LG 4-weeks—bundles of nerve fibers (*) surrounded by spaces (arrowheads) and the perineurium (thin arrow) (magnification: ×10 bar: 100 μm). (e) PG—weeks—the nerve fibers (*), the perineurium (thin arrows), and blood capillaries (arrows) are noted (mag: ×10, bar: 100 μm). (f) LPG—4 weeks—reveals the bundles of nerve fibers (*), the space between the fibers (arrowheads) and capillaries (arrows) (mag: ×10, bar: 100 μm). (g) CG—8 weeks—normal nerve fibers (*) divided into bundles by perineurium (thin arrow) and blood capillaries (arrows) (mag: ×10, bar: 100 μm). (h) EG—8 weeks—bundles of nerve fibers (*), the perineurium region (thin arrows), and blood capillaries (arrows) (mag: ×10, bar: 100 μm). (i) IG—8 weeks—nerve fibers (*), capillaries (arrows), the perineurium (thin arrows), and the spaces between the fibers (arrowhead) (mag: ×10, bar: 100 μm). (j) LG—8 weeks—bundles of nerve fibers (*), the perineurium region (thin arrows), and blood capillaries (arrows) (mag: ×10, bar: 100 μm). (k) PG—8 weeks—bundles of nerve fibers (*) and blood capillaries (arrows) similar to the CG (mag: ×10, bar: 100 μm). (l) LPG—8 weeks—nerve fibers (*), the perineurium (thin arrows), and blood capillaries (arrows) similar to the CG (mag: ×10, bar: 100 μm).
