Objective- To present a new technique of suturing fresh massive wounds with skin flap in equine regardless of the flap direction and/or location.
Design- Experimental in vivo study and clinical trial.
Animals- Nine healthy donkeys for experimental study and 28 horses with different injuries that varied in shape and location for clinical trial.
Procedures- All injuries were repaired using the new technique. Flap survival length and viability were assessed over three week's period both clinically; through observing skin texture and appearance, hair depilation as well as wound healing; and histologically through skin biopsy at 7, 14 and 21 days after surgery to evaluate the healing process.
Results- Clinical cases showed excellent wound healing in all flaps. Histologically, all flaps showed good healing by day 7, and at 21 days all the underlying space was filled with normal s.c. tissue.
Conclusion and Clinical Relevance- This new technique is a rapid and successful fieldprocedure for the treatment of fresh massive wounds with skin flap in equine without the need of sophisticated equipments yet with good results.

Objective- To evaluate greater omentum as an autogenous free graft in enhancing bone healing. Design- Prospective descriptive trial. Animals- Ten mongrel adult dogs, 3 to 4 years old and weighing 25.2 to 31 kg, assigned into two equal experimental and control groups (5dogs/group), were used. Procedures- Mid-shaft osteotomy on right radius was followed by a partial omentectomy in all dogs. A 30x30 mm2 piece of greater omentum was prepared as a free graft. Then, it was positioned over the osteotomy site in the experimental dogs. After 8 weeks, the dogs were euthanized and both operated and intact radii were harvested in each dog and subjected to a three-point bending test. Results- The values of biomechanical parameters in operated bones of both groups were lower than those in intact bones. The percent of reduction in biomechanical values of the operated bones in experimental group was significantly less than control group. Conclusions and Clinical Relevance- The results of this study suggested that autogenous greater omentum as a free graft could enhance the biomechanical aspects of bone healing in dogs. Application of autogenous greater omentum as a free graft might advantageously promote fracture healing process in the dogs at risk of developing delayed or nonunion fractures.

Objectives- To assess the ectopic bone formation in canine masseter muscle following the implantation of the natural bovine bone minerals (NBM) loaded with canine mesenchymal stem cells (MSCs).
Design- Experimental study.
Animals- four mongrel dogs.
Procedures- Tripotent MSCs isolated from the canine bone marrow were loaded onto the NBM sponges and allowed to adhere. The cell-loaded scaffolds were then implanted in parallel with cell-free control scaffolds in masseter muscles of four mongrel dogs. Eight weeks after, the animals were sacrificed and the ectopic bone formation in implantation site was studied using the sections prepared from the parts of the muscle containing the implants. Furthermore, the amount of bone formation in two studied groups was quantified using Image-Pro Plust software.
Results- The implants from the both groups were appeared to be encapsulated by fibrous tissue in implantation site which included some trabecular bone containing osteocyte and osteoblast. There were no indications of inflammation and foreign body reaction, nor were there any indications of cartilage tissue formation. In contrast to control, in MSCs group, lamellar bone was observed in some area. More importantly, in cell loaded scaffolds more amount of bone was formed compared to that of control cell free scaffolds (P<0.05).
Conclusion and Clinical Relevance- Taken together it seems that in vivo bone forming capacity of the NBM sponges would be improved by loading it with MSCs.

Objective-To determine the effect of ultrasound therapy on hydroxyproline (HP) content in superficial digital flexor tendon (SDFT) in horses.Design - Experimental in vivo study.Animals - Eight adult castrated horses.Procedure- The mediocaudal surface of right metatarsal bone in was exposed and after complete separation of SDFT, it was splitted (striking 15 times) in full thickness in longitudinal fashion of 10 cm in length in the mid-tendon area using BP blade no 24. These animals were divided into two equal groups of control and experiment. No treatment was given to control one, whereas; treatment group was subjected to therapeutic ultrasound (Sonopulse 434) regimens 10 minutes daily with intensity of 1 Watt/Esq. at 3 MHz frequency over 14 days. The hydroxyproline concentration was measured by modified spectrophotometery. The collected data was analyzed using student t test at p <0.05 significant level.Results- HP content of severed tendons in both groups was significantly less than normal tendons (P<0.01). Also, the HP content of treatment group was significantly more than the control group.Conclusion and Clinical Relevance- The results of this study indicated that direct application of ultrasound therapy on severely injured or extensive lesion of superficial digital flexor tendon in horses will enhance HP content in the treated tendon.

Objectives- To determine normal circulatory pattern of distal limbs of goat to be used for comparison with diseased digits or hooves of small ruminant lameness examination.
Design- Experimental study.
Animals- Forelimbs and hindlimbs of 10 healthy goats of both sexes, were collected fresh immediately after slaughter.
Procedures- The plantar and Palmar artery were dissected and catheterized by eighteen gage catheters. 10 ml contrast medium was injected by the catheter. Radiographs were obtained in lateral and dorsoplantar and dorsopalmar views respectively. Fine details of blood vessel were evaluated in radiographs.
Results- The medial digital artery of the forelimb descends on the medial side of the medial digit and terminates at the bulb of claw by anastomosing with the corresponding proper digital artery. The lateral digital artery arises from the deep arch, passes down on the lateral side of the lateral digit and is distributed similar to the medial side. The lateral digital artery and the medial digital artery meet each other and anastomose together at the toe and sole forming a uniform network of marginal capillaries. The main blood supply of the digits region in the hindlimb is essentially the distal extension of those vessels on the dorsal and plantar aspects of the metatarsus similar to the fore limb. The lateral digital artery and the medial digital artery meet each other and anastomoses together at the toe and sole forming a uniform network of marginal capillaries.
Conclusion and Clinical Relevance- No report could be found in the literature regarding arteriographic evaluation of the foot in small ruminant. This study is describing normal arterial pattern of goat's distal limb.

Objective-comparative evaluation of different surgical methods of vesicoureteral reflux induction in rabbits.
Design- Elective experimental study.
Animals- sixteen healthy male rabbits.
Procedures- sixteen healthy New Zealand White male rabbits were randomly divided in four equal groups. All rabbits were preoperatively evaluated with retrograde cystography for the presence or absence of congenital or acquired vesicoureteral reflux. Rabbits of group1 (control) without any manipulation were kept for comparing with other three experimental groups. Rabbits of group 2, 3 and 4 undergone open surgeries with unroofing the ureter with surgical blade incision of 3-5mm in length. In group two incised ureter left without suturing ureteral mucosa, in group three incised ureter sutured with nylon material 5-0 and in group four ureter was incised with electrosurgical cutting blade without suturing mucosal layer to the bladder roof. Postoperatively on days 7th, 15th and 30th all animals in different groups undergone cystography for presence or absence of vesicoureteral reflux.
Results- All the animals of group 1, 2 and 4 didn't show any reflux in double contrast cystography but in group 3 reflux in the form of bilateral and unilateral were observed clearly.
Conclusion and Clinical Relevance- Unroofing the ureter with surgical blade incision and suturing the incised margins can induce the successful vesicoureteral reflux for undergoing an experimental study of vesicoureteral reflux treatment.

Alireza
Ghadiri
Reza
Avizeh
Case description- A three-month-old male German Shepherd dog, with signs of instability to stand, ataxia and radiographic symptoms of chondrodysplasia is presented. The symptoms were developed since birth.
Clinical Findings- On physical examination, the affected pup did not show any swelling, pain or other abnormality in the long bones by palpation, but he had ataxia in walking. Ocular examinations revealed no lesions. In radiography, the distal right and left ulnar metaphysis were flattened and the physes were much wider than normal. The carpal bones were smaller in size than those in normal age. An increased radiopacity (sclerotic band) in the metaphyseal part of both radial and ulnar bones was observed adjacent to the physes. Radiographs were also taken from ribs and there was no abnormality in costochondral junctions.
Treatment and outcome- There is no specific treatment for this disorder. The pain can be alleviated with anti-inflammatory/analgesic drugs (eg. aspirin). In this case, the dog was euthanized upon the owner’s request. According to the radiographic findings and our clinical observation, chondrodysplasia was diagnosed.
Clinical Relevance- There is no definitive treatment for such cases and the management program depends on the owner and the veterinarian decisions. It is better to stop breeding of these animals.
