Quantification of immunohistochemistry of types I and III collagen in tendon repair. The staining of types I and III collagen was quantified in 1) staining area (A and C) and 2) staining intensity (B and D). In M + S group, the area of type I collagen was significantly increased from day 6 to day 14. The staining area of type III collagen was indifferent among the three groups. The area ratio of type III collagen over type I collagen in M + S group was greater than in the Sut group at day 6 (E). No differences were detected in average intensity of types I and III collagen, individually and the ratio (F), among the three groups.
