The present study was aimed to record and analyze the prevalence of obstructive urolithiasis in domestic animals like cattle, buffalo, horse, goat, sheep, dog and cat presented at RVP-TVCC, Indian Veterinary Research Institute. A total of 777 cases were reported during the academic session starting from April 2018 to March 2019 from Bareilly and its surrounding regions. Incidence were highest among ruminants 92.92% comparing to other domestic animals 7.08%. Among the different animal species, caprine were found to be the most affected, followed by buffalo and canine. A positive correlation was noted between the occurrence of obstructive urolithiasis and the season with maximum number of cases being reported during the winter season December -February. The female to male ratios in urolithiasis affected animals were 1:81, 1:75 and 1:22 for buffalo, goat, and dog, respectively indicating higher occurrence in male animals. Majority of the goat 67.89% and buffalo 84.80% presented with obstructive urolithiasis were also found to be fed exclusively with a grain rich diet that are excess in phosphorous thereby contributing to urolith formation. The role played by behavioral changes associated with different seasons and the dietary status of the animal plays a significant role in the pathophysiology of urolithiasis. Such an interplay between the season and the dietary imbalance will lead to higher incidence of obstructive urolithiasis in domestic animals.

The purpose of the work was to study the relationship between the indicators of insulin resistance (IR), free radical oxidation products (FRO) levels, and the antioxidant system activity in adolescents with androgen deficiency (AD).Materials and methods. 58 adolescents 13­—18 years old with AD were examined. Serum levels of total testosterone, glucose, insulin, tiobarbituric acid active compounds (TBA), carbonylated proteins (CB), glutathione peroxidase (GPx), superoxide dismutase (SOD), and catalase (CAT) activity were determined. The HOMA index and the coefficient of oxidative stress were calculated.Results and discussion. In the group of adolescents with AD without IR, an inverse correlation was found between the HOMA index and CAT activity. CAT activity negatively correlated with CB content and glucose concentration. In addition, an inverse relationship was found between the activity of GPO and SOD. IR indices indirectly, through feedback with the activity of CAT, influence to the formation of conditions for inhibition/activation of FRO of proteins.IR was revealed in 37.9 % of the examined adolescents with AD. Direct relationship was recorded between IR indicators and markers of oxidative stress, as well as between testosterone levels and GPx activity in the group of these patients. Direct correlation between the coefficient of oxidative stress and the content of TBA-­active compounds indicates the formation of oxidative stress due to the activation of lipid peroxidation. Reduced testosterone levels in adolescents with AD inhibits an increase in GPx activity and prevents compensation for excessive intensity of free radical processes. Conclusion. The results indicate that adolescents with AD have a close relationship between the processes of carbohydrate metabolism, FRO, and antioxidant protection.In adolescents with AD without IR, a balancebetween the studied parameterswas found.The formation of IR in adolescents with AD shifts the equilibrium of the oxidative balance towards the activation of FRO processes. Decreased testosterone levels in adolescents with AD do not maintain the body’s antioxidant status within normal limits.
