This study aimed to investigate the efficacy of PRP and dextrose PRL in stifle joint arthritis in rabbits.Sixteen healthy adult male rabbits were allocated into groups A (n=8) and B (n=8). After induction of arthritis in all experimental animals, the animals of group A were treated with intra-articular injection of PRP, while the animals of group B were treated with dextrose PRL. Pain scoring was evaluated by the Simple Descriptive Pain scale at 0d, 6d, 13d, and 19d, while radiographic scoring was examined by Kellgren and Lawrence grading system at pre-induction, post-induction, and post-treatment. The hematological parameters, including PLT, HB, WBC, PCV, RBC, monocytes, and lymphocytes, were assessed in blood samples at 0d, 6d, 13d, and 19d. We observed that Pain scoring showed a significantly lower (P<0.05) value in group A than in group B at 13d and 19d. Radiographic scoring was significantly lower (P<0.05) in group A than the group B during post-treatment. However, during the pre- and post-monoiodoacetate (MIA) induction, there was no significant difference (P>0.05) in radiographic scoring between both groups. The PLT concentration was increased, and monocyte was decreased in the group A animals than the group B animals at 13d and 19d (P<0.05), while WBC, RBC, PCV, HB, and lymphocyte concentration showed no significant difference (P>0.05) between both groups. In conclusion, the application of PRP is an effective method for treating stifle joint arthritis compared to the dextrose PRL in the rabbit model.

The study was designed to determine the role of adding hyaluronic acid as a supportive filling material to improve grafting process of experimentally defective tibial bone in dog model. Eighteen local breed dogs of both sexes weighted 18± 0.4 kg and aged (12± 0.6Months) were randomly allocated in two equal groups. In the first group, twelve dogs underwent experimental tibial bone defect (2.5×0.7 cm ) and replaced with deprotenized lamb ribs. The second group were treated as that for the first, but supported by adding 1% hyaluronic acid, to their grafts. The bone in both groups was firmly fixed by cerclage wire. All dogs were; followed-up clinically, radiologically and macroscopically at (14, 30 and 60 days after the intervention. In all study dogs the systemic infections, signs of seromas, hematoma and sever lameness were not developed along the period of the study . Grossly, dogs in the second group at 60 days showed an increase in the size of the filler of bone at the edges and in the mid of the defect, improvement and acceleration in the bone healing, and formation of bone bridges compared to the first group. Radiological finding exhibited complete healing of the fixated bone segment with the surrounding area; however, some cortical irregularities denoted chronic periosteal reaction and callus formation in the treatment with hyaluronic acid. In conclusion, the study indicated that hyaluronic acid with xenograft materials exhibited remarkable beneficial effects on improvement of the tibial bone defect augmentation

The goal of this study was to assess the effects of the Hematopoietic Progenitor Cells (HSCs) on full-thickness cutaneous wounds healing in rabbits. Twenty clinically healthy adult New Zealand White rabbits were used in this study; under aseptic technique and general anesthesia full-thickness excisional cutaneous wound; 20 mm x 20 mm were made on the back. The rabbits were randomly partitioned into two. In first group (control group), the wounds were treated with 3ml of saline solution. In second group (Hematopoietic Progenitor Cells- group); wounds were treated with 5x106 (Hematopoietic Progenitor Cells). The result of molecular evaluation along the interval of following-up recorded a significant differences (P<0.05) of the level Fibroblasts Growth Factor (FGF) and Vascular Endothelial Growth Factor (VEGF) recorded at 7, 14 and 35 day post-surgical operation in (Hematopoietic Progenitor Cells- group) compare than control group. These outcomes were parallel with the finding of the clinical and histopathological assessment showed that Hematopoietic Progenitor Cells- group reduces inflammation and promotes epithelialization during 3th weeks with increased vasculature than those in untreated wounds. This study confirms that local implantation of Hematopoietic Progenitor Cells leads to enhance and develop of cutaneous wound healing in rabbit model.

This study was designed to compare the efficiency of using conventional acupuncture (CA) and electroacupuncture (EA) in the laminitis therapy in race horses, twenty adult race horses with laminitis were randomly selected. Clinical examination was carried out and acupuncture points were determined according to the results of diagnostic palpation of acupuncture. The horses were grouped into two equal groups; the 1st group was treated daily for 6 consecutive weeks, with CA and the 2nd group with EA. evaluation of lameness was depended on the visual and objective examination using the “American Association of Equine Practitioners” (AAEP) lameness scale and confidence stride lengths criterion for forelimbs which performed by the force plate indices. The lameness level was statistically analyzed applying t-test and Wilcoxon signed-rank analysis and p-value (P<0.05) was significant. Both visual and objective lameness examinations showed gradual statistical significant reduction (P<0.05) in the severity of lameness and improvement in the gait of the horses after CA and EA treatment. It is also showed that the lameness level was significantly (P<0.05) decreased after every weekly session of EA treatment in comparison with CA treatment. It is concluded that continued EA treatment by current study pattern showed a marked improvement in the movement of the laminitic horses when compared with CA treatment.

In secondary fracture healing, callus proliferate, undergo hypertrophy and the extracellular matrix becomes calcified. This step to some extent, recapitulates the embryological bone development with a combination of cellular proliferation and differentiation, increasing cellular volume and matrix deposition. The causes of the chondrocytes volume increase in secondary bone healing are poorly known, but cell membrane transporters perhaps could be implicated. We hypothesize that NHE-1 and AE-2 are among plasma membrane transporters that have a role in cellular differentiation and regulation of endochondral ossification for secondary bone fracture healing. Study of closed tibia fracture healing in 2 groups of 25 of 8-weeks-old Sprague-Dawley rats were undertaken and histological evaluation were made at 5 different time points at 1, 2, 3, 4, and 6 weeks after induction of the fracture. Histological evaluation of proliferative and hypertrophic chondrocyte zone area showed a significant difference in week 1 compared to other weeks. Immunohistochemistry study revealed a significant high level of labeling intensity of NHE-1 at the first four weeks. While labeling intensity of AE-2 showed moderate reaction at 1 and 2 weeks, that increased and reached the highest level at 3 and 4 weeks. These results suggested that NHE-1 and AE-2 had role in the endochondral ossification of secondary bone healing.
