This study aimed to investigate the relationship between the sperm quality and the osteopontin (OPN) concentration in the prostates of Malakli shepherd dogs. Ejaculates were collected once by digital manipulation from 39 male dogs aged between 2 and 4 years and older. The first and third fractions of the ejaculate were centrifuged at 5000× g for 30 min, and supernatants were stored at −80 °C for further analysis of OPN using a double-antibody sandwich method (SEA899CA, Cloude-Clone Corp, Houston, TX, USA). Meanwhile, the second fractions were evaluated for sperm motility, concentration, viability, and rate of abnormal spermatozoa (head, acrosome, midpiece and tail abnormalities). The average concentration of OPN was 8.7 ± 5.2 ng/mL, and it differed significantly between the 1st 10.4 ± 5.3 ng/mL and 3rd 7.4 ± 5 ng/mL fractions. According to ROC (receiver operating characteristic curve) analysis, the OPN concentration had a better diagnostic ability for sperm motility (p < 0.001) than for the rate of abnormal spermatozoa (p < 0.05). Additionally, the OPN concentration was negatively correlated with poor sperm morphology and motility. In conclusion, the OPN concentration in prostate-derived secretions may be a possible marker of sperm quality in dogs. Further research could explore the involvement of OPN in sperm motility during cryopreservation and in vivo fertility.

Background and objective: This study aimed to assess the protective ability of edaravone on testicular torsion–detorsion injury in rats.Methods: Eighteen adult male Sprague–Dawley rats were randomly divided into three groups: Sham group (control, n = 6); testicular torsion/detorsion (T/D group, n = 6) and T/D+edaravone (T/D+E group, n = 6). The spermatic cords of rats of the T/D group and the T/D+E group were rotated 720° in a clockwise direction and maintained for 120 min in this torsion position. Around 90 min after the torsion, edaravone at a dose of 10 mg/kg dissolved in saline was administered IP to the T/D+E group. The testicle was counter‐rotated to its normal position to allow reperfusion for 4 h. Left testes of each animal were excised 240 min after beginning of reperfusion. Oxidative stress markers (TAS, TOS, SOD, and MDA) and apoptotic pathways (Caspase 3, Caspase 8, Caspase 9, Bcl‐2, and Bax,) were assessed by ELISA methods. Also, testicles were subjected to the histopathologic and ultrasound examinations.Results: Ultrasound imaging showed that edaravone reduced the surface area and increased vascularization in testicles with T/D (p < 0.0001, p < 0.05, respectively). Edaravone pretreatment markedly decreased the levels of MDA, TOS, Bcl‐2, Bax, Caspase 3, Caspase 8, and Caspase 9 (p < 0.0001). Also, it increased significantly TAS levels (p < 0.0001) and reduced insignificantly SOD activity. Histopathologic examinations demonstrated that edaravone significantly attenuated the histological damage caused by T/D in testicles.Conclusion: Taken together, the findings indicate that pretreatment of edaravone has protective effect against testicular T/D injury.

It was aimed to evaluate the regressive effect of grayanotoxin-rich Turkish mad honey and 5-fluorouracil (5-FU), separately and together by using the N-methyl-N-nitrosourea (MNU)-induced colon cancer modelling in rats. Study groups were designed as control group (CG), cancer control group (CCG), 5-Flourouracil group (FUG), Turkish mad honey group (HG), Turkish mad honey and 5-FU combined group (FU-HG). White blood cell (WBC), lymphocyte, eosinophil, basophil, serum lactate dehydrogenase (LDH), total oxidant status (TOS), and total protein values of the rats in the CCG were significantly lower than the values of the rats in the CG, whereas serum Bcl-2 and survivin levels were significantly higher in the rates belonged to the CCG in comparison to those in the CG. The presence of anaplastic epithelial cells, vascularization, precancerous changes, and inflammatory infiltration detected in the colon and small intestine of the rats in FU-HG, FUG, HG were less intense (P<0.05) compared to the findings in the rats in CCG. In conclusion, mad honey and 5-FU reduced anaplastic cell growth and oxidative stress via suppressed anti-apoptotic activity. Considering the histopathological findings in the liver and kidney, no toxicity occurred related to mad honey and 5-FU metabolization. Therefore, the combined use of these two substances may be an alternative method in the treatment of colon cancer.

Tr en Flor kimyasal reaktivitesi yüksek bir elementtir. Bu element toprak, kaya, kil, kömür, su ve havada iyonlar ve bileşikler halinde bulunur. Endüstriyel florozis ve doğal afetler sonucu toprak ve sudaki flor konsantrasyonunun artmasına bağlı flor zehirlenmeleri meydana gelmektedir. Organik florürler surfaktan, fiber, membran, pestisit, fungusit, uranyum, ilaç, tomografik görüntüleme maddesi ve diş bakım ürünü üretiminde kullanılmaktadır. Bu elementin uzun süreli alınan günlük miktarı güvenli eşiği aştığı takdirde florozis olarak bilinen kronik flor zehirlenmesi ortaya çıkmaktadır. Ülkemizde, bugüne kadar yapılan çalışmalarda Muğla, Eskişehir, Kırşehir, Çorum, Ankara, Konya, Hatay, Van ve Ağrı illerinde su, toprak, bitki, koyun idrarı, diş ve kemik örneklerinde flor düzeyleri belirlenmiş ve flor zehirlenmesi hakkında değerlendirmeler yapılmıştır. Bu kapsamdaki bilgi birikiminin özlü bir şekilde bir araya getirilmesinin güncel durumu ortaya koyacağı ve bu konuda yapılabilecek çalışmalara katkı sağlayabileceği kanaatindeyiz. Fluorine is a highly reactive chemical element. This element is present in soil, rock, clay, coal, water and air as ions and compounds. Organic fluorides are being used in the production of surfactant, fibers, membrane, pesticide, fungicide, uranium, drug, tomographic imaging agent and dentifrice. In various studies carried out in our country, natural and industrial fluorosis and fluoride-induced biochemical changes in animals were studied. In our country, Muğla, Eskişehir, Kırşehir, Çorum, Ankara, Konya, Hatay, Van and Ağrı cities and water, soil, plant sheep urine, tooth and bone materials examined for fluor amount despite the long work done over the years, some of the effects of fluoride on the body is still not fully explained. Therefore, to be useful to make a compilation about the characteristics of fluorine, and its' presence in the nature, and its' biodynamics and effects in the body, was thought.

Periodontal diseases are the most common diseases in veterinary medicine. The first clinical finding is chewing difficulty, saliva flow and bad oral odor. It further develops into plaque and tartar formation, gingival inflammation and hemorrhagic appearance of the gingiva, periodontal pockets formation, alveolar bone resorption and tooth loss. In this study an evaluation has been made to determine which degree reflects on the parameters of systemic inflammatory reaction with special attention to IL-6 (Interleukine-6), CRP (C-reactive protein), osteopontin, superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GPx) and Ig (Immunglobulins = Total protein – Albumin) and hematological parameters in dogs with periodontitis. Two groups have been defined in this study. The first group included 10 healthy and owned dogs as a control group. The second group consisted of 10 owned dogs with moderate-severe periodontitis. The difference between monocyte (p <0.001) and neutrophil (p <0.05) counts was found to be significant. In addition, the difference between SOD, MDA, glutathione peroxidase, CRP, IL-6 measurements in group 1 and group 2 was significant. (p <0.001). The level of osteopontin in moderate-severe periodontitis cases was found significantly higher than the level measured in the healthy group. Measured values in the moderate-severe periodontitis cases are higher than the healthy group in terms of CRP, IL-6, and osteopontin levels. Increasing severity of periodontitis was associated with changes in oxidative stress parameters: increased MDA, decreased SOD and glutathione peroxidase levels. These differences provide important information about the evaluation of the cellular responses. There is a need for continued research into the systemic impact of periodontal disease.

This study aimed to evaluate systemic inflammation, oxidative stress and lipid profile in cats that had either naturally gained excess weight or had developed obesity. The following groups were examined in the study: ten obese cats with a body condition score of (BCS) >8 (the obesity group), ten overweight cats with a BCS score of >6 (the overweight group) and ten ideal weight cats with a BCS score of 4-5 (the control group). In the cats that had either gained too much weight or had become obese, the serum AST (P < .001), albumin (P = .002) and total protein (TP) (P < .001) levels were found to be significantly higher than the values determined in the control group cats. Furthermore, blood serum high-density lipoprotein (HDL) (P = .009) and triglyceride (TG) (P < .001) levels in cats that had developed obesity were found to be significantly higher than the values defined in the control group cats. In the obese cats, serum procalcitonin (PCT), paraoxonase-1 (PON-1), total thiol, native thiol and MDA levels were found to be significantly higher than in overweight cats (P < .001). As a result, it was concluded that it would be useful for veterinarians to consider significant changes in parameters related to liver function and lipid metabolism, as well as to emphasize systemic inflammation and oxidative stress in their clinical evaluations in cats that had either naturally gained excess weight or had developed obesity.
