Objective- To determine the effects of the Hydrocortisone on in vitro growth of fibrobla sts isolatedfrom the distal aspects of the horses limbs.
Design- Experimental in vitro study.
Animals- A total of 4 Caspian miniature and 4 mixed thoroughbred horses.
Procedures- Under generalanesthesia and aseptic condition, a full thickness of skin incision was created on the lateral aspects of themetacarpal mid-third and 3 grams of subcutaneous tissue was harvested and placed on culture medium(RPMI-1640) in an incubator at 37°C in 5%C02. The Hydrocortisone was added in 3 different concentrations [treatm ent groups A (l014 g/ml) , B (100 14g/ml), and C (300 14g/ml)] into the culture medium and cellcounting was carried out after 4 days. The effects of Hydrocortisone added to control media were comparedwith a control media on fibroblast growth and viability. The data were analyzed by one way ANOVA andTukey test.
Results- There were no significant differences in fibroblast growth rate and viability percentage (p>O.05)between the groups control and A, but the groups Band C suppressed significantly the fibroblast growthand decreased viability percentage in compared with groups control and A (p<0.05), and also there were nosignificant differences between groups Band C in fibroblast growth rate and viability percentage (p>0.05).
Conclusion and Clinical Relevance- The effect of Hydrocortisone on cultured fibroblast growth isdose-dependant. Application ofthis agent can inhibit fibroblast growth; therefore it can be used for treatmentofexuberant granulation tissue and improving wound healing processes, especially in the distal limb woundsof the horses

Objective- To evaluate tail vertebra as an autogenous cortical bone and cancellous bone for filling ulnarsegmental bone defect in dogs.
Design- Experimental study.
Animals- Eight adult mongrel dogs with an average age of 37.S months and average body weight of17.62 kg.
Procedure- The animals were randomly divided into two groups. A bone defect (2.S-cm) was created on the middle portion of the right ulna in all dogs. Ulna was fixed by intramedullary pinning. In 5 dogs (test group) ulnar bone defects were filled with tail vertebra, after tail docking. Cancellous bone harvested fromthe il iac cres t was also used to promote bone healing in the ho st-graft inter face s. In the other 3 dogs(control group) ulnar bone defect s were not filled. Po stoperative clinical assessment was includ edmeasurement of body temperature, heart rate, respiratory rate, and evaluation of the degree of lameness. Radiographic assessment of bone based on the process of bone healing and consolidation of the host-graft interface, periosteal reaction, and soft tissue swelling were performed immediately and at the weeks 1, 3, S,7, 10, 13 and 17 after surgery.

Objective- The liver has a unique location in the body for performing multiple functions such as, metabolism, detoxification and synthesis. There are limitation for liver transplantation due to shortage of available donors and requires for sophisticated technology and support surgical teams. The purpose of this study was to investigate the hepatocyte transplantation into the spleen of animal model such as dog to establish basic condition for further studies.
Design- In vivo experimental Study.
Animals- Five Iranian indigenous mixed breed dogs of both sexes, 15/8±3 months old and 19.6±8.2weighting were used in this study.
Procedures- Ventral midline celiotomy was performed under general aneasthesia and liver sampls were obtained using suction technique by a 50cc syringe and 14 gauge needle. Then obtained samples were injected into the same dog 's spleen directly and also via splenic artery, the celiotomy incision sutured and the animal left to recover. On the 16th postoperative day, under general anaesthesia, the gross appearance of spleen were recorded and photographed and for histopathological evaluation, partial splenectomy was performed. The prepared sections were stained with Hematoxylin Eosin [H& E] and Periodic Acid Schiff[PAS] and studied under light microscope.
Results- The gross evaluations of the removed spleen showed a whitish area at the injection site in all of the 5 transplanted dogs, spleen vessels had been dilated and enlarged in diameter. Microscopically the groups of hepatocytes in the center of lymphoid follicles in the white pulp were noted.
Conclusion and Clinical Relevance- Hepatocyte transplantation could be useful for both supporting an acute liver failure and for surviving as a bridge to liver transplantation in terminal liver failure.

Objectives- Using conjunctival graft to replace experimental mucosal defects of teat sinus.
Study- Experimental study.
Animals- Five healthy, mature, lactating, Jersey cows.
Methods- Conjunctival mucosal grafts with teat cannula were evaluated in the repair of experimental teat sinus mucosal lesions. A 1.5xl em wide circumferential strip of mucosa was resected from each teat in five Jersey cows. Each lesion was then treated by one of the three methods: 1. teat cannula (C ); 2. Conjunctivalmucosal graft and teat cannula (C+G); 3. Only mucosal graft (G). All teats were evaluated 4 weeks after treatment, for patency and luminal diameter by radiography and ultrasonic examination. The cow s were euthanized, and teats were collected for histopathologic study.
Results- The histopathologic and radiographic results showed that the conjunctival tissue of the teat was incorporated by the teat mucosal tissue. Some acanthosis in conjunctiva was observed, due to the stimulation of the teat cannula.
Conclusion and Clinical Relevance- Conjunctival grafts can be used in teat mucosal defect s when other therapeutic methods fail to keep the integrity of the teat sinus mucosa.

Objective- Although the promotional effects on bone healing of pulsed electromagnetic fields (PEMF)have been well demonstrated, the effects of static magnetic fields (SMF) remained unclear. In this study, effects of SMFs on clinical and biomechanical aspects of bone healing using a canine unstable osteotomy gap model were investigated.
Design- Prospective descriptive trial. Animals- Fifteen mongrel dogs, 4 to 5 years old and weighing 15.5 to 21.3 kg.
Procedures- After an osteotomy of the midshaft radius, bone healing was evaluated over an 8-week period in control dogs (n = 5) and experimental dogs exposed to medium (700 gauss) (MSMF) and high (1500 gauss) (HSMF) magnetic fields (n = five/each group). Bone healing was assessed clinically and biomechanically.
Results- Dogs exposed to HSMF had more improved lameness scores in contrast to the MSMF and control dogs. Significantly, greater forces
