Abstract
titania (titanium dioxide, TiO2) is known to induce neurotoxicity and CNS dysfunctions. Numerous studies have explored the neuroprotective effects of melatonin against neurotoxicity. This study evaluates the potential of melatonin to protect against titania-induced neurotoxicity and the role of the Keap1/Nrf2/ARE signaling pathway. One group of animals were treated with Titania (0.045 and 0.075 g/rat) alone while the other with added melatonin (1 mg/kg and 3 mg/kg) and behavioral alterations were assessed using OFT (open field test). Neurochemical and histopathological changes were also studied in the hippocampus by analyzing kelch ECH associating protein 1 (Keap1), nuclear factor erythroid 2-related factor 2 (Nrf2), and antioxidant response element (ARE). It was seen that the animals with added Melatonin had improved behavioral scores in the OFT, like anxiety and motor dysfunction triggered by TiO2. Melatonin also reduced lipid peroxidation, ROS, GSSG, IL1β, TNFα, Bax, and Keap1 levels, but boosted GSH, GPx, GR, SOD,IL10,IL4, Bcl2, Nrf2, and ARE levels and improved quadruple mitochondrial enzyme complex activity in titania-treated animals. Histopathological examination showed melatonin induced cytoprotection against vacuolization and necrosis in granular cells of DG and pyramidal cells of CA1 area of the hippocampus. In our study, pretreatment with melatonin reduced titania-induced neurotoxicity in the hippocampus through a mechanism potentially mediated by the Keap-1/Nrf2/ARE pathway.

Abstract
Objective Colonic anastomosis is associated with serious complications leading to significant morbidity and mortality. Fibroblasts have recently been introduced as a practical alternative to stem cells because of their differentiation capacity, anti-inflammatory, and regenerative properties. The aim of this study was to evaluate the effects of intramural injection of fibroblasts on the healing of colonic anastomosis in rats. Materials and Methods Inbred mature male Wistar rats were used in this experimental study (n=36). Fibroblasts were isolated from the axillary skin of a donor rat. In the sham group, manipulation on descending colon was done during laparotomy. A 5 mm segment of the colon was resected, and end-to-end anastomosis was performed. In the control group, 0.5 ml of phosphate buffer saline (PBS) was injected into the colonic wall and in the treatment group, 1×106 fibroblasts were transplanted. Following euthanasia on day 7, intra-abdominal adhesion, leakage and peritonitis were evaluated by necropsy. Mechanical properties were assessed using bursting pressure and tensile tests. Inflammation, angiogenesis, and collagen deposition were examined histopathologically. Results The mean scores for adhesion and leakage were decreased in the treatment group versus control samples. Lower infiltration of inflammatory cells was observed in the treatment group (P=0.03). Angiogenesis and collagen deposition scores were significantly increased in the fibroblast transplanted group (P=0.03). Tensile mechanical properties of the colon were significantly increased in the treatment group compared to the control sample (P=0.01). There was no significant difference between the control and treatment groups in terms of bursting pressure (P=0.10). Positive weight changes were found in sham and treatment groups, but the control rats lost weight after 7 days. Conclusion The results suggested that allotransplantation of dermal fibroblasts could improve the necroscopic, histopathological, and biomechanical indices of colonic anastomosis repair in rats.

Abstract
The purpose of this study was to evaluate the effects of ascorbic acid (AA)-treated fibroblasts transplantation on excisional diabetic wound healing. An excisional wound was created between the shoulders of streptozotocin-induced diabetic rats. On day three, 1 ml of PBS, 1 × 106 intact homologous fibroblasts, and 1 × 106 fibroblasts treated with 50 μM AA were injected subcutaneously around the wound edges in control, treatment-1 and treatment-2 groups, respectively. In the sham group, the wound was left intact. Wound area was measured by planimetry. On day 15, samples were harvested for histopathological examination and hydroxyproline content. Wound area in treatment-1 and - 2 groups was significantly decreased compared to other groups, on days 11 and 15. The hydroxyproline content was significantly lower in the control group compared to the other groups. Histopathology revealed significant increases in the number of neovessels, macrophages, lymphocytes and fibroblasts in the treatment-2 group compared to the other groups. Trichrome staining showed the highest level of collagen deposition and orientation in the treatment-2 group. In conclusion, allotransplantation of 50 μM AA-treated fibroblasts could result in progressive healing and improved reparative indices of excisional dermal wound in diabetic rats.

Abstract
Naringenin is one of the most important and abundant known flavonoids found in grapefruit and other citrus fruits. This experimental study aimed to assess the clinical effects and immune responses of naringenin in the animal model of rheumatoid arthritis (RA) according to various reports on its anti-inflammatory effects and modulation of the immune system. To this end, 40 Wistar rats in the weight range of 160-180g were randomly assigned to four groups (n=10) including healthy, control, naringenin, and methotrexate orally treated groups. To induce RA disease, a compound of 200 μl of Freund's adjuvant and collagen type II was injected subcutaneously into the rear footpads of rats. The severity of RA clinical signs was assessed based on a standard scoring method. The treatment lasted for three weeks (days7-28 after induction). The obtained data pointed out that the levels of C-reactive protein (CRP), myeloperoxidase, nitric oxide, IL-17, and IFN-γ cytokines significantly increased in the RA rats, while the level of their serum antioxidants significantly reduced, compared to the healthy rats. The inflammation of the paws and the level of CRP decreased similarly in both methotrexate and naringenin-treated groups. In the naringenin-treated group, a further decrease was detected in serum myeloperoxidase, nitric oxide, and the total antioxidant capacity occurred, as compared to the methotrexate-treated rats. Nonetheless, IL-17 and IFN-γ cytokines levels were further decreased in the methotrexate-treated group. Accordingly, it can be concluded that naringenin can be effectively used for the reduction of inflammatory effects and control of RA disease.

Abstract
This study was aimed to evaluate canine vasocystotomy as a testosterone-preserving method of sterilization and investigate its potential post-operative complications. Five healthy adult male dogs underwent surgical procedure to transplant vasa deferentia to the urinary bladder. Under general anesthesia, caudal abdomen was opened and both vasa deferentia were ligated and transected. Then, the proximal free ends were sutured to mucosal layer of urinary bladder on its cranio-dorsal aspect. Serum testosterone level was measured on a weekly basis. Six-week postoperative assessments were performed including semen and urine sampling, ultrasound, contrast vasography, and tissue sampling. Statistical analyses revealed no significant differences in serum testosterone levels compared to its baseline value. Along with non-motile and broken spermatozoa, no cast or crystals were observed in urine samples. Semen analyses revealed azoospermia. No vasal obstruction or contrast leakage was observed in vasographs indicating bilateral patency in all dogs. Normal thickness of the bladder was found in ultrasounds. Histopathology showed normal testicular architecture and no inflammatory response was found in bladder or vas deferens following vasal transplantation. No significant change was found in testicular volume at the end of the study. This study suggested that vasocystostomy could be considered as an alternative method for canine sterilization with no significant changes in the testosterone concentrations and no evidence of postoperative complications. The preservation of testosterone could be regarded as an advantage and makes this approach favorable compared to the routine methods of sterilization especially for herding and guard dogs, because it prevents overpopulation while maintains the functionality.

Abstract
The black proventriculus is a necropsy finding sign observed during post-mortem examinations of dead young chicks up to 10 days of age and due to variation in color of the affected proventriculus organ, it may be ignored in some cases, in particular when the disease occurs simultaneously with other well-recognized infections of two weeks old chicks. In late January 2018, several live and dead chicks with a history of an unusual increase in mortality showing no clinical signs but sudden dead were referred to the poultry clinic of Faculty of Veterinary Medicine, Urmia University, Urmia, Iran. General routine postmortem examination revealed color changes (light green to dark green color) in the wall of proventriculus together with some degrees of congestion in the lungs and liver of the dead chicks. Microbiology tests revealed that the causative agent was Escherichia coli strain O142 and histopathological examination indicated that the color changing of the organ was due to necrosis of glandular epithelium with locally extensive or diffuse hypercellularity by lymphocytes and macrophages with hemorrhages. In conclusion, black proventriculus due to E. coli strain O142 was responsible for the sudden death of young chicks and based on antibiogram, selective antibiotics should be used for the treatment of the affected flocks.

Abstract
This investigation was undertaken to verify the prevalence of helminths parasites in the gastrointestinal tract of catfish. A total number of 116 catfish (Silurus glanis) were collected from Zarrine-roud river and examined for helminths. Fish were examined after washing contents of gastrointestinal tract and observed for the presence of helminths using a stereo microscope and a light microscope. Results indicated that 18.96% of the examined catfish were infected with digenean trematodes including Orientocreadium siluri (27%), Crowcrocoecum skrjabini (39%), and cestode Bothriocephalus gowkongensis (34%). All the parasites were found in the intestine. Mid-gut followed by foregut appeared to be the most commonly infected parts of the alimentary tract of hosts. The results showed that there was a significant correlation between infection rate, catfish body size, and weight (P < 0.05).
