Tendon injury is a medical indication that requires surgical therapy and prolonged recovery. Collagen plays a crucial role in the wound healing process. Collagen maintains homeostasis, interacts with platelets, and enhances cellular components. Most living organisms consist of collagen components as fibrillar proteins. In this study, the potential properties of type-1 collagen from sea cucumber and Tilapia-skin were evaluated depend on proximate analysis, amino acid composition, and moisture-absorption ability. The result showed that Tilapia-skin has a higher protein and fat composition compared to the sea cucumber. In contrast, moisture, ash, and yield composition showed higher for sea cucumber compared to Tilapiaskin. Meanwhile, based on amino acid analysis was revealed that proline, alanine, methionine, isoleucine, leucine, phenylalanine, and lysine were lower on sea cucumber compared to Tilapia-skin. In conclusion, both type-1 collagen material from sea cucumber and Tilapia-skin might be developed as a biomaterial for tendon injury. It is crucial that further studies be carried out to emphasize the potential of biodegradable and bio-replaceable materials using the in vivo model.

Fractures are known to be high-risk traumatic cases in domestic animals. Surgery was performed to reposition and immobilize bone using a plate as a biomaterial component. This study aimed to evaluate the radiographic and histological findings in canine femur after implantation of a 304 stainless-steel-based plate. A total of six male dogs aged 3-4 months were used in this study. Dogs were acclimatized for a week and then randomly assigned to 2 groups and 3 replication, respectively. The left femoral diaphysis was cracked and fixed by (A) commercial plate; (B) 304 stainless-steel plate. Radiographic observations were performed at 24 h and 28 d postoperatively during the recovery period. Histological figures were evaluated at 28 d postoperative descriptively. As a result, physical examination of muscle tissue in both groups did not reveal discoloration, swelling, and fluid accumulation around the plate. The radiographic figures presented a slight callus production around the crack and a decrease in the gap between cracks after 28 d. The histological figures observed the proliferation of osteoblasts, osteocytes, connective tissues, and bone trabeculae. It can be concluded that no significant difference between 304 stainlesssteel plate compared to commercial plate. A 304 stainless-steel-based plate is recommended for bone immobilization in canine femoral fractures.
