ABSTRACT
BACKGROUND: The aim of this study was to examine variations in stress, metabolic, and physiological parameters of horses used in the traditional equestrian team sport of Kök-Börü in relation to winning and losing outcomes. MATERIAL AND METHODS: To accomplish this, blood samples were taken from horses on four different teams who participated in two separate games, both before and after game. These samples were used to measure levels of cortisol, ACTH, beta-endorphin, adrenaline, noradrenaline, triiodothyronine (T3), and thyroxine (T4) via species-specific commercial ELISA kits. The autoanalyzer tested biochemical and hematological parameters. The gathered data were then analyzed statistically based on the teams' winning or losing status. RESULTS: The results suggested that winning teams had lower MID, red blood cell, HGB, RDW-SD, HCT, platelet distribution width, and creatine kinase values post-game in comparison to their pre-game state. Conversely, mean corpuscular hemoglobin concentration (MCHC), mean corpuscular hemoglobin (MCH), and CREA values increased in the winning teams' post-game. Additionally, horses in the winning teams showed a decrease in cortisol, beta-endorphin, and ACTH levels post-game but increased levels of adrenaline and T3. Considering the pre-game values, it was found that GRA and Cl levels were lower in the winning teams. Before the game, adrenaline and T3 levels were higher in the winning teams. No significant difference was observed in post-game hematological parameters between the teams. However, post-game K, adrenaline, and noradrenaline levels were higher among the winning teams' horses, while cortisol and beta-endorphin levels were heightened in horses from the losing side. CONCLUSION: In conclusion, significant differences were not observed in the distribution of hematological and biochemical parameters of horses following the Kök-Börü games, regardless of the outcome. However, decreased post-game cortisol, ACTH, and beta-endorphin levels in winning teams may suggest better stress management abilities among these horses.

OBJECTIVES: Prolidase plays a vital role in collagen turnover, matrix remodeling, and cell growth. We aimed to evaluate the association between treatment with chorionic gonadotropin and infertility and erectile dysfunction by investigating tissue prolidase activity, oxidative stress, and levels of antioxidant enzymes. MATERIALS AND METHODS: The 16 male Wistar albino rats used in this study were randomly divided into 2 groups: rats treated with human chorionic gonadotropin (hCG) and control rats (n = 8 in each group). The rats in the hCG group were subcutaneously injected with 50 IU hCG daily for 15 days, while the rats in the control group were subcutaneously injected isotonic saline. All of the rats were sacrificed by a lethal overdose of sodium pentobarbital at the first month after hCG administration. Prolidase activity and levels of malonyl aldehyde, glutathione reductase, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) were estimated in the testicular and penile tissue. The testicles and penis were transversely dissected and placed in formalin. RESULTS: Levels of prolidase and malonyl aldehyde in the testicular and penile tissues were significantly higher in the hCG group than in the control group (p < 0.001), while levels of glutathione reductase, SOD, GSH-Px, and CAT were significantly lower in the hCG group than in the control group (p < 0.001). CONCLUSIONS: In this study, we observed that treatment with hCG increased prolidase activity and oxidative stress and decreased the antioxidant capacity of penile and testicular tissues; therefore, this may affect fertility and erectile function.
