Reproductive dysfunction is a common consequence of both obesity and diabetes. This study investigated the impact of obesity and diabetes, alone or combined, on physiological reproductive parameters in male rats.Twenty-four male Wistar Albino rats were divided into four groups: Control; obese non-diabetic; diabetic; and obese diabetic. Obesity was provoked by consumption of a high-fat diet (HFD) consisting of 40% energy from fat for 90 days. Diabetes was induced by an intraperitoneal injection of streptozotocin at a dose of 40 mg/kg/day for three consecutive days. Semen, histopathological, and morphometric analyses were carried out. Serum testosterone, luteinizing hormone (LH), and vaspin and visfatin were measured using ELISA kits. Hypothalamic Kiss-1 mRNA was detected using qPCR and pituitary nitric oxide (NO) was determined using Griess reagent. Our results showed a decrease in semen quality parameters, testosterone, and LH levels with degenerative changes in the testes in experimental groups when compared to control group. This had a positive correlation with hypothalamic Kiss-1 and a negative correlation with pituitary NO and serum vaspin and visfatin. In addition, adverse effects were more pronounced in animals with obesity and diabetes combined compared to rats who were either diabetic or obese. In conclusion, obesity and diabetes, alone or combined, had a negative impact on male rat fertility. Moreover, obesity and diabetes combined had more harmful effects on male fertility when compared with obesity alone. Hypothalamic Kiss-1, pituitary NO, and serum vaspin and visfatin may play a role in the pathophysiology of male infertility-associated with obesity and diabetes.

Introduction. Peripheral nerve injury is a frequently encountered clinical problem that leads to functional losses at the long- -term. Although microsurgical repair has been introduced to clinical practice in peripheral nerve injuries, unsatisfactory outcomes regarding functional recovery in target organ cause an increasing interest on studies about nerve injury and biology of the recovery in nerve injuries1. Material and Methods. Sciatic nerves of seventy adult Sprague Dewly rats were transected and primary anastomosis was performed. Rats were then divided into three groups: Control group, while 30 rats were repaired with sutures, and the remaining 30 were repaired with fibrin glue. After 30 days the rats were sacrified and the sciatic nerves were investigated histologically with morphometrical and statistical analyses. Results. In microsurgical nerve repair, suture placement has been thought to cause hindrance to the sprouting axons and compress the blood supply to the fascicles, thereby impairing the regeneration of the transected nerve ends after repair, with possible neuroma formation. On the other hand, fibrin glue is a simple, effective technique, less time consuming than suturing. Another advantage of this suture-free technique is that it avoids injuring the axon with needles, and the lack of foreign bodies minimizes the inflammatory reaction. Conclusion. We recommend using fibrin glue as it demonstrates less inflammatory reaction, less scar tissue formation, it is less time consuming and provides better outcomes.
