“…Obtaining a satisfactory result compared to placebo treatment, in relation to hoof growth rate, spatial relationship between the third phalanx and the corneal case, vascular perfusion and lamellar healing process. Biological membranes derived from animal tissues have been studied and used mainly in surgical repairs of hernias in veterinary medicine (Vidor et al 2013;Marques et al 2015) and as dressings for external wounds and grafts (Aceto et al 2007;Queiroz et al 2012). In the present work, biological membranes derived from bovine tunica albuginea were used in conjunction with tenorrhaphy, with the aim of evaluating their ability to aid healing.…”

“…The testicles, in general, have a thin capsule of connective tissue called the tunica albuginea, which does not present much difference in its histological architecture and anatomy among domestic animal species. It is composed of dense connective tissue, characterized by a greater quantity of collagen fibers and a smaller number of cells, compared to loose connective tissue (QUEIROZ et al, 2012).…”

Tendon rupture and lacerations are orthopedic problems of great importance in veterinary medicine. Many times, animals are discarded or removed from athletic life due to ruptured tendons. Therefore, new therapeutic possibilities have been used to improve and accelerate tendon healing. The objective of the work was to evaluate the use of a biological membrane derived from bovine tunica albuginea and stem cells in tenorrhaphies in veterinary medicine. Thirtyone adult Wistar rats were used, subdivided into 4 experimental groups, the control group (CG) with 4 animals, the tenotomy group (GT), the biological membrane group (GMB) and the stem cell group (GCT), each with 9 animals. The albugineous tunics were collected and underwent cleaning, conservation and quality analysis, making them ready for use. Three young Wistar rats were used to extract subcutaneous adipose tissue for stem cell cultivation. After the surgeries, the animals were euthanized in 3 moments; 7, 14 and 21 days postoperatively, where they were evaluated macroscopically and microscopically. The GT and GMB demonstrated low quality of healing and inflammation at almost all evaluated moments. The GCT presented a much better result, in relation to all the parameters evaluated between the groups, low tendon inflammation, no limb edema, much higher quantity and quality of collagen and demonstrating rapid healing and high tissue quality. We conclude that stem cell therapy in cases of tendon ruptures is very promising.

“…Biomaterials such as acellular bladder matrix (ZHAO et al, 2015;LI et al, 2016), pericardium (ALBRECHT et al, 2015), tunica vaginalis (WONGSETTHACHAI et al, 2011;FARIA et al, 2020), swine intestinal submucosa (ROSSETTO et al, 2013), peritoneum (OLIVEIRA et al, 2008), amniotic membrane (IIJIMA et al, 2007;ADAMOWICZ et al, 2012) and ileum (FERREIRA et al, 2005) have been reported in bladder repair surgery. Several studies have shown the tunica albuginea as a useful biomaterial due to its low cost, easy collection, conservation, and processing (QUEIROZ et al, 2012;OLIVEIRA et al, 2015;MORAES et al, 2017.…”

“…Tunica albuginea is a thick capsule of dense connective tissue, which surrounds the testicle (JUNQUEIRA & CARNEIRO, 2017). It is rich in collagen fibers organized in two layers: the external has longitudinal collagen fibers orientation and the internal layer has circularly bundle dispositions, which enable tissue tensile strength (QUEIROZ et al, 2012). Considering that bovine tunica albuginea is an available, easy handling and inexpensive biomaterial, this research was motivated by the lack of reports of its use as xenograft in rats' urinary vesicle.…”

Bovine tunica albuginea conserved in honey as xenograft for cystoplasty in rats

Urinary bladder damages leading to few viable bladder tissue available might demand a challenging reconstructive surgery. In this context, biomaterials are valid alternatives for bladder reconstruction. This study evaluated the bovine tunica albuginea fragment as graft material for cystoplasty in rats and honey-preserved implant viability.Thirty Wistar rats were assigned to two groups: (1) a test group (T) with a circular 1.0-cm-diameterbovine tunica albuginea graft application in the apex region by a continuous absorbable (Polyglactin 910 5-0) suture with stitching of all bladder layers and (2) a simulation group (S) in which animals underwent only partial cystectomy. In addition, each of these groups was further divided into three subgroups according to euthanasia period on post-surgery day 7, 15 and 30.Two animals had self-limiting hematuria at postsurgical period. At necropsy, frequent crystals and adhesion to the peritoneum were observed. At the histopathological evaluation, animals from the T group euthanized by 15th postoperative day had layers disorganization and initial muscle development, while T group rats euthanized by 30th postoperative day showed complete urothelization. Urothelization pattern was similar in both groups. Moreover, the muscular layer formation was present in both groups, but more evident in S group animals. Nevertheless, inflammatory infiltrate and neovascularization were remarkably more intense in T group rats.It might be concluded that bovine tunica albuginea graft was successful in repairing rats’ bladder, being a good biomaterial option in reconstructive urinary vesicle surgery.

“…Therefore, a scaffold with a mechanical force that facilitates the regeneration process and amplifies bladder capacity and complacency is required [8]. In this regard, some studies had good results using tunica albuginea biomaterial as tissue engineering [9][10][11][12][13]. The tunica albuginea is a thick capsule of connective tissue, composed of two layers of collagen bundles [14,15].…”
