Abstract
Three horses were found to have an extensive nasopharyngeal cicatrix that was responsible for respiratory impairment. The cicatrization was diagnosed by use of endoscopy during evaluations of the horses for inspiratory stridor. All 3 horses were treated by endoscope-guided transnasal incision of the cicatrix and were able to resume their previous activities.

Abstract
Dorsal laminectomy and durotomy were performed at thoracic vertebrae 12 and 13 (T12-T13) and lumbar vertebrae 1 and 2 (L1-L2) in 12 normal dogs. A free fat graft harvested from subcutaneous tissue adjacent to the incision was placed over the T12-T13 laminectomy site. A 75 X 25 X 5 mm pedicle fat graft harvested from a similar location was placed over the L1-L2 laminectomy site. Three dogs each were euthanatized at weeks 2, 4, 8, and 16. With both types of fat grafts, an initial inflammatory stage reduced the size of the graft approximately 50%. Axonal degeneration and demyelination of the spinal cord resolved by week 16. At week 16, the durotomy sites had healed, but the dura mater was adhered to the spinal cord. No difference between the grafts could be demonstrated by antemortem myelography and cerebrospinal fluid analysis. There was no demonstrable advantage to the use of pedicle fat grafts.

Abstract
A Quarter Horse stallion developed an abscess over the left gluteal region after an IM injection of antihistamine. The wound healed with considerable fibrous scarring and some persistent granulation tissue. The lesion was static for 2 years before the granulation tissue went through a 6-month period of progressive enlargement. At that time, histopathologic diagnosis of squamous cell carcinoma was made from excisional biopsy. Six months after diagnosis, the horse had lost body weight and the lesional diameter had further increased, so the horse was euthanatized.

Abstract
Delayed closure is an underutilized technique that can produce a good cosmetic result in lower leg wounds and can significantly shorten the healing time. To be successful, the surgeon should be able to utilize tension-relieving techniques and manage dead space. Scar revision should be limited to simple elliptical excision or modifications thereof until experience is developed. Sliding skin flaps, Z-plasties, and W-plasties are used infrequently and require adequate preoperative planning.

Abstract
Skin expansion was used in three horses, one heifer, and one dog to aid in the repair of cosmetic defects. Skin expansion was produced by inserting an expandable silicone device subcutaneously and gradually inflating the device with saline. Skin expansion allowed skin to be mobilized and sutured over cosmetic defects without excessive tension. A successful outcome was achieved in four of the five cases reported here. In one animal, two attempts to create a pocket for a silicone prosthesis failed because the expanders ruptured. Complications included implant failure, wound dehiscence, and exposure of an expander. Skin expansion can be used to enable closure of skin defects in areas where skin tension usually precludes repair by local transposition.

Abstract
Nasopharyngeal cicatrices were observed endoscopically in 47 horses examined because of abnormal respiratory noises and/or exercise intolerance. A review of these cases revealed a correlation between cicatrization and age, sex, and the presence of other upper airway abnormalities. The age of affected horses ranged from 6 to 21 years, with a mean age of 12.7 +/- 7.8 (+/- 2 SD) years. Females were affected 2.7 times more frequently than males. Abnormalities commonly observed with a nasopharyngeal cicatrix included chondritis of the arytenoid cartilage, epiglottic deformity, and deformity of the guttural pouch openings. The nasopharyngeal cicatrix was responsible for respiratory obstruction in only 3 horses. Treatment for the cicatrix was not performed on any horse in this series. Generalized nasopharyngeal and laryngeal inflammation were postulated as causes of the cicatrices and associated abnormalities.

Abstract
An esophageal stricture was diagnosed in a 9-month-old quarterhorse by esophagoscopy and positive pressure contrast esophagography. Medical management and two attempts at surgical intervention were unsuccessful. The initial surgical technique used was a linear esophagotomy, mucosal resection and anastomosis, and closure of the muscular tunic, which resulted in a more severe stricture. The second surgical procedure was interruption of the stricture cicatrix by a single linear esophagotomy and primary closure of only the esophageal muscular tunic. This technique resulted in an increased lumen diameter, but failed to adequately resolve the stricture. Successful resolution of the stricture with return to a normal diet was achieved by a two stage repair using formation of an esophagostomy to stabilize the esophagus, followed by fenestration of the mucosal-submucosal cicatrix. Six months postoperatively, the horse was asymptomatic on a normal diet.

Abstract
Injuries of udder and legs of dairy cows in a changed production environment were studied in two herds. The frequency of injuries of udder and teat skin decreased in the renovated tying stall. The stall length and also the cubicle length was too short for large cows in old cowsheds which caused lesions on the skin of udder and legs. The new concrete on floors was rough and kept the wearing of hooves moderate. The yoke tying and the low level of manger worsened the fore leg conditions in the renovated tying stall. In the new loose house the incidence of injuries did not change markedly.

Abstract
The histological appearance of cells and tissues in the reparative scar tissue which forms in the equine superficial flexor tendon following partial rupture was compared to that of normal tendon. The repair fibroblasts were found to be larger and more basophilic than the tenocytes of normal tendon, to have large vesicular nuclei and to resemble the 'myofibroblasts' described in scar tissue elsewhere. The cell to matrix ratio in scarred zones of tendon was found to be increased and the concentration of collagen in these areas was less than in normal tendon. However, the scar tissue collagen was more readily extractable and contained a different pattern of collagen types. Normal equine tendon was found to be composed almost exclusively of type I collagen whereas the scarred tendon had substantial quantities (20 to 30 per cent) of type III collagen in addition to type I. The presence of type III collagen in the scarred tendon was confirmed by indirect immunofluorescence using antibodies to purified type III collagen. These observations suggest that tendon scar tissue is not derived from proliferating tenocytes but from mesenchymal cells resting in peritendinous connective tissue or blood vessels. As a result of the presence of type III collagen, the scarred tendon is also likely to have less tensile strength than normal tendon.

Abstract
Skin lesions known as "tattoos", were observed in several captive Atlantic bottlenosed dolphins (tursiops truncatus) maintained at the Naval Ocean Systems Center, San Diego, California. Biopsy of typical lesions and subsequent ultrastructural examination revealed intracytoplasmic particles with poxvirus morphology.

Abstract
The skin grafting experiments were carried out on the cannon regions of horses to throw light on four matters relating to split skin transplantation. They were: The thickness of donor split skin that would provide good wound cover and still leave adequate tissue to permit uneventful healing at the donor site; whether split skin grafts were more readily accepted on fresh than on granulating wounds; the size of wounds that would benefit from grafting; and the maximum size of graft that would be readily accepted. The findings were: Split skin grafts 0.76 mm thickness gave the best results although grafts 0.63 mm thickness were satisfactory; split skin grafts were accepted more readily on fresh wounds than on granulating tissue; wounds which exceeded 1/10th of the skin area on the cannon region justified grafting; the upper limit in size was not established as the largest grafts used were more readily accepted than smaller grafts.
