| Objective. The vast majority of type 1 diabetes leads to a higher prevalence of reproductive
system’s impairments. Troxerutin has attracted much attention owing to its favorable properties,
including antihyperglycemic, anti-inflammatory, and antiapoptotic effects. This investigation was
proposed to evaluate whether pretreatment with troxerutin could prevent apoptosis-induced testicular
disorders in prepubertal diabetic rats.
Methods. Fifty prepubertal male Wistar rats were randomly allocated into five groups: control
(C), troxerutin (TX), diabetic (D), diabetic+troxerutin (DTX), and diabetic+insulin (DI).
Diabetes was induced by 55 mg/kg of streptozotocin applied intraperitoneally. In TX and DTX
groups, 150 mg/kg troxerutin was administered by oral gavage. Diabetic rats in DI group received
2–4 U NPH insulin subcutaneously. Troxerutin and insulin treatments were begun immediately on
the day of diabetes confirmation. After 30 days, the testicular lipid peroxidation and antioxidant
activity, apoptosis process, and stereology as well as serum glucose and insulin levels were assessed.
Results. The results showed that diabetes caused a significant increase in the blood glucose, the
number of TUNEL positive cells and tubules, and the malondialdehyde level as well as a significant
decrease in serum insulin level compared to controls. The stereological analysis also revealed various
alterations in diabetic rats compared to controls. Troxerutin treatment improved these alterations
compared to the diabetic group.
Conclusion. Troxerutin-pretreatment may play an essential role in the management of the type-1
diabetes-induced testicular disorders by decreasing blood glucose and modulating apoptosis. |
