Biological membranes are used as implants in veterinary reconstructive surgery in order to restore the function and structure of damaged tissues. Various tissues from animals, kept by different techniques and implanted in recipients of the same or different species, help repair wounds where extensive tissue loss or the inability to scarring is evidenced. Although the benefits of biological membranes outweigh their disadvantages, their use in clinical and surgical routines is rare, largely due to ignorance of their characteristics, handling and implantation. The present article aims to review general aspects on biological membranes, from procurement to possible complications of their use, through experimental studies and previously reported cases, and to encourage their use as a biomaterial implant in case of anatomical defects, traumatic wounds, oncological postoperative care, and traumas in general.

The rupture of the cranial cruciate ligament (CCLR) characterizes itself for a partial or a total laceration of the cranial cruciate ligament. Patients with ligament (partial or total) acute laceration present acute lameness, with total or partial incapacity of sustentation of their weight on the affected leg. The clinic therapy with conservative drugs must be used previously to the surgical treatment. The tepoxalin, a no steroid anti-inflammatory can be indicate in the reduction of the inflammatory process and relieve of the pain, caused by acute and chronic musculoskeletal disturbances. It promotes a balanced blockade of the brake of the arachidonic acid by the lipoxygenase and cycloxigenase rote of the inflammatory cascade. Thus, the purpose of this study was to evaluate the tepoxalin efficiency in CCLR conservative treatment, though specific clinical test, radiographic exams, and cytological analysis of the articular liquid. Ten dogs with CCLR, between male and female were enclosed on this study and they received a dose of 10mg/kg of tepoxalin daily. The lameness, arc movements test in maximum extension of the leg and digit pressure, as well as, the articular liquid analysis after 28 days of treatment, allow to conclude the effectiveness of the tepoxalin in the CCLR conservative treatment. It promoted the return to the normal deambulation in all treated cases, and it can be considerate one more option of AINE on the treatment of this artropathy.

Ocular tumors are frequent in the eye clinic of small animals. They can be primary or secondary, and its location within the eyeball or its attachments may trigger consequences ranging from the loss of aesthetics to affecting the eye’s functionality. This article presents a case of conjunctival angiokeratoma in a five-year-old female dog of Neapolitan Mastiff breed, in the Small Animal Clinic of <em>Universidad Cooperativa de Colombia</em> in Ibagué. The patient was treated for presenting ocular alteration in her left eye characterized by an increase of volume and hyperemia of the third eyelid conjunctiva, with a two-year evolution. During the ophthalmic examination, ocular mucosanguineous discharge, conjunctival hyperemia and follicular conjunctivitis were found. After general and ophthalmic clinical examination was performed, a biopsy of the lesion was performed for a histopathologic evaluation, which determined angiokeratoma in the third eyelid conjunctiva, a rare neoplasia in this type of tissue and in this breed. The treatment used in this case was surgical removal, with favorable results, which led to a complete removal of the tumor without sequelae in the patient.
