    Abstract A prospective clinical study consisting of six bovines (200–300 kg body weight) undergoing open tibial fractures was carried out, to evaluate the use of circular and hybrid external skeletal fixation (ESF) systems for open tibial fracture repair in large ruminants. The ESF systems consisting of 4 full rings (n = 2), 8 half-rings (n = 1), 2 full rings with 2 sidebars (n = 2) or 2 full rings with 4 sidebars (n = 1) were used to treat open tibial fractures. The healing progress of the animals was evaluated based on different clinical and radiographic examinations. The level of fracture reduction, alignment, and fixation ranged between satisfactory to adequate in all the animals. The fixators were well tolerated and maintained by the animals till the complete repair of the fracture. Adequate fracture healing with satisfactory functional recovery was observed in all the animals in about 3–4 months. The different designs of ESFs were found to provide adequate stability in open tibial fractures in animals weighing 200–300 kg. However, the fixators need to be evaluated in numerous clinical cases to establish their suitability in routine clinical settings.

    Abstract Objective: Quantitation of mechanical properties of a novel locking compression plate (LCP) for bovine tibia.
    Study design: Prospective in vitro study.
    Sample population: Adult Murrah buffalo (250-350 kg) tibiae.
    Methods: Forty tibiae were randomly assigned to five treatment groups (n = 8/group): intact bone and bone constructs with a standard nonlocking plate, single LCP, double LCP, and novel LCP. During implant application, a mid-diaphyseal, oblique osteotomy was performed in all constructs, which were subsequently tested in axial compression (n = 4 each) or three-point craniocaudal bending (n = 4 each). Novel LCP alone (n = 4) was tested only in bending. Stiffness, yield load, ultimate failure load, and bending moment were determined from the load deformation curves and compared among different treatment groups (P < .05).
    Results: Under compression, yield load of the novel LCP (24.07 ± 3.45 kN) was greater than that of the nonlocking plate (11.10 ± 2.46 kN) and the single LCP (18.01 ± 2.07 kN) but less than that of the double LCP (30.61 ± 1.95 kN), and ultimate failure load of the novel LCP (25.85 ± 4.32 kN) was greater than that of the nonlocking plate (13.18 ± 2.91 kN) but similar to that of the single LCP (21.17 ± 2.33 kN) and the double LCP (32.40 ± 1.46 kN). Bending moment, yield load, and ultimate failure load of the novel LCP were 565.37 ± 79.30 Nm, 7.90 ± 1.14 kN, 9.83 ± 1.38 kN, respectively, which were greater than those of the nonlocking plate and the single LCP but comparable to those of the double LCP.
    Conclusion: The novel LCP developed for bovine tibia was mechanically superior to the standard nonlocking plate or the single LCP and comparable to the double LCP.
    Clinical significance: The novel LCP may provide rigid fixation of tibial diaphyseal fractures in buffaloes and cattle weighing 250 to 350 kg.

    Abstract The present study evaluated healing potential of bone marrow-derived mesenchymal stem cells (BM-MSCs) and BM-MSCs-conditioned medium (BM-MSCs-CM) for acute and subacute injuries in the rabbit peripheral nerve injury model. The regenerative capacity of MSCs was evaluated in 40 rabbits divided into eight groups, four groups each for acute and subacute injury models. BM-MSCs and BM-MSCS-CM were prepared by isolating allogenic bone marrow from the iliac crest. After inducing sciatic nerve crush injury, different treatments consisting of PBS, Laminin, BM-MSCs + laminin, and BM-MSCS-CM + laminin were used on the day of injury in the acute injury model and after ten days of crush injury in the subacute groups. The parameters studied included: pain, total neurological score, gastrocnemius muscle weight and volume ratio, histopathology of the sciatic nerve and gastrocnemius muscle, and scanning electron microscopy (SEM). Findings indicate that BM-MSCs and BM-MSCS-CM have augmented the regenerative capacity in acute and subacute injury groups with a slightly better improvement in the subacute groups than the animals in acute injury groups. Histopathology data revealed different levels of regenerative process undergoing in the nerve. Neurological observations, gastrocnemius muscle evaluation, muscle histopathology, and the SEM results depicted better healing in animals treated with BM-MSCs and BM-MSCS-CM. With this data, it could be concluded that BM-MSCs support the healing of injured peripheral nerves, and the BM-MSCS-CM does accelerate the healing of acute and subacute peripheral nerve injuries in rabbits. However, stem cell therapy may be indicated during the subacute phase for better results.

    Abstract Background and aim: Adipose tissue-derived stromal vascular fraction (SVF) contains a heterogeneous cell population comprising multipotent adipose-derived stem cells. Regenerative therapy using adipose-derived SVF has broad applications in bone tissue engineering due to the superior osteogenic potential of SVF. This study was designed to standardize and characterize adipose-derived SVF obtained from New Zealand white rabbits for bone tissue engineering and other potential applications.
    Materials and methods: Ten skeletally mature and clinically healthy adult New Zealand white rabbits were used in this study. The SVF was prepared using surgically resected interscapular adipose tissue following enzymatic digestion with 0.1% collagenase type I solution. The SVF pellet obtained after the final centrifugation step was suspended in a 0.5 mL control solution to obtain ready-to-use adipose-derived SVF. The freshly prepared SVF was characterized based on the total SVF cell count and cell yield per gram of adipose tissue. The SVF cells were enumerated using a hemocytometer.
    Results: Interscapular adipose tissue depots are ideal for preparing autologous adipose-derived SVF due to the ease of access. The interscapular adipose-derived SVF prepared by enzymatic digestion had an average cell yield of 3.15±0.09×10
    Conclusion: The enzymatic digestion of adipose tissue using 0.1% collagenase resulted in better cell yield per gram than methods previously reported in rabbits. The use of adipose-derived SVF can preclude the requirement for an additional culture period. In addition, it may also reduce the risk of extensive cell contamination, which makes it a safe and cost-effective strategy for bone tissue engineering applications.

    Materials and methods: The atrophic non-union fracture model was developed by creating a 10 mm segmental bone defect in the radial diaphysis of five adult New Zealand White rabbits. The periosteum (2 mm) of the cut bone ends was cauterized using electrocautery to induce atrophy. Atrophic non-union was confirmed using radiographic and histologic evaluations on 30th postoperative day.
    Results: The radiographic signs of healing were completely absent in all the rabbits on 30th postoperative day, indicating inert bone ends. Histological findings further confirmed the presence of inert bone ends, indicating the development of atrophic non-union.
    Conclusion: The combination of the segmental bone defect, electrocautery induced thermal damage of bone end periosteum, and delayed treatment can induce the development of atrophic non-union fracture model in rabbits that can replicate the clinical scenario.

    Abstract Background and objective: Platelet-rich plasma (PRP) is a category of platelet concentrate that has been widely used as a therapeutic modality in musculoskeletal medicine. The present study was conducted to classify and code the non-activated platelet-rich plasma (nPRP) derived from New Zealand white rabbits for tissue engineering and other regenerative medicine applications.
    Methods: PRP was prepared from the whole blood by double centrifugation protocol using a laboratory centrifuge. The prepared nPRP was characterized using the parameters such as platelet dose, the relative composition of platelets, WBC, and RBC. The production protocol was described using the parameters such as platelet enrichment factor, factor increase in WBC concentration, platelet capture efficiency, WBC-reducing efficiency, and RBC-reducing efficiency. The nPRP was also classified and coded using the most recent and universally accepted classification and coding systems.
    Results: The non-activated leukocyte-poor red cell-rich PRP had an average platelet count of 1875.75 × 10
    Conclusion: The protocol described in this study can be used to prepare non-activated leukocyte-poor red cell-rich PRP (Red-PRP IC1) from rabbits that can be coded as 318-00-00.

    Abstract Prospective, randomized clinical trials were performed in sixteen clinical cases of urolithiasis in male goats, managed with two different anaesthetic treatments (A and B). Animals of group A were premedicated with dexmedetomidine (2.5 μg/kg body wt), while in group B dexmedetomidine (2.5 μg/kg body wt) and butorphanol (0.05 mg/kg body wt) were used intravenously. Induction of anaesthesia was achieved by 1% propofol in groups A (2.50 ± 0.37 mg/kg) and B (1.99±0.29 mg/kg). The anaesthesia was maintained with continuous intravenous infusion (CII) of 1% propofol. Infusion rate was adjusted in response to positive reactions to surgical nociceptive stimulation performed during tube cystostomy procedure. In both groups, heart rate (HR), respiratory rate (RR) and rectal temperature (RT) decreased significantly (P<0.05) in both groups. Mean arterial pressure (MAP) decreased significantly (P<0.05) after premedication, up to the end of observation period in both groups. However, MAP improved at 20 min and onwards but remained significantly (P<0.05) lower than the baseline value up to the end of observation period. It was concluded that both combinations cause significant cardiovascular and respiratory depression and should be adminised carefully in uraemic goats.

    Abstract Stem cell therapy has been extensively evaluated for its potential in managing neuronal diseases and disorders. The present study was performed to evaluate the therapeutic potential of allogenic bone marrow-derived mesenchymal stem cells (aBM-MSC) for the management of neural defects associated with vertebral compression fracture (VCF) in canine. Six clinical cases presented with the history of neural defects secondary to non-deviating VCFs were included in the present study. All the animals were subjected to detailed clinical, radiological, and haematological investigations and observations were recorded. The neurological defects in each case were graded based on routine neurological examination. The aBM-MSCs were isolated, cultured, and characterized as per ISCT criteria from the bone marrow collected from healthy dogs presented for elective surgery. The prepared cell suspension containing aBM-MSC at 3rd passage was utilized for transplantation in the clinical cases of VCF. Following the intraspinal administration of aBM-MSC, the dogs were treated with methylcobalamin and gabapentin orally throughout the study period. Improvement was evaluated on the basis of a detailed neurological examination. Significant improvement in locomotor status and sensory functions was observed in all the cases. Findings of the present study suggest that intraspinal administration of aBM-MSCs along with supportive therapy can be recommended as a therapeutic strategy for managing neural defects associated with non-deviating VCFs in canine patients.
