Granulocyte colony-stimulating factor (G-CSF) is a glycoprotein commonly used in the field of medicine to treat neutropenia. Granulocyte colony-stimulating factor has also crucial roles in ameliorating the ischemia/reperfusion (I/R) injury in particular tissues. In this study, we aimed to investigate the protective effect of G-CSF on ovarian damage in experimental ovarian I/R injury. Thirty adult female rats were used. Rats were separated randomly into 5 groups; Group 1: sham group (abdominal wall was opened and closed surgically), Group 2: torsion group with 3-hour ischemia using vascular clips. Group 3: torsion + G-CSF group with 3-hour ischemia 30 minutes after the administration intraperitoneal (i.p.) of 100 µg/kg of G-CSF. Group 4: torsion-detorsion group with 3 hour ischemia and 3 hour reperfusion. Group 5: torsion-detorsion + G-CSF group with 3 hour ischemia followed by 100 µg/kg of G-CSF i.p. administration 30 minutes prior to 3 hour of detorsion/reperfusion. Ovarian tissue damage was scored on histopathology. Ovarian tissue malondialdehyde (MDA) was measured biochemically. In comparison with the sham group, both the torsion and torsion-detorsion groups had significantly higher scores for follicular degeneration, vascular congestion, edema, hemorrhage, and leukocyte infiltration ( < .05). When compared group torsion-detorsion + G-CSF to group torsion-detorsion, parameters aforementioned significantly decreased in group torsion-detorsion + G-CSF ( < .05). Granulocyte colony-stimulating factor has also decreased MDA levels notably both in the torsion + G-CSF and torsion-detorsion + G-CSF groups ( < .05, < .01). Our experimental study suggests that G-CSF can be a novel agent for the treatment of ovarian I/R injury.

Introduction: No rapid test to diagnose testicular torsion (TT) exists. The usefulness of trans-scrotal near-infrared spectroscopy (NIRS) remains to be proven in children. Here, we measured testicular oxygenation (StO%) in children with unilateral TT and compared values to those measured in children with another cause of testicular pain and in control subjects.

Background: Testicular torsion is a urological emergency that requires prompt surgery to prevent orchiectomy. Pharmacological interventions may slow the progression of damage and reduce reperfusion injury after surgical correction.
Purpose: This study evaluated the protective effects of linezolid against testicular torsion-detorsion (T/D) injury in rats by focusing on the mechanisms involving the Toll-like receptor 4 (TLR-4) pathway.

Testicular torsion, a medical condition contributing to male infertility, results in severe scrotal pain and ischemia. Oxidative stress factors contribute to germ cell death following surgical reperfusion, suggesting postoperative pharmacotherapy could mitigate testicular ischemia/reperfusion (I/R) injury. Ivermectin, a GABA receptor modulator for treating parasitic infections such as onchocerciasis, has demonstrated anti-oxidative stress and anti-apoptotic properties.

Our study aimed to investigate the antidiabetic, antioxidative, and antiapoptotic effects of liraglutide on the testes of rats with diabetes and ischemia/reperfusion injury. Subjects were divided into three groups: control, diabetes, and torsion groups. Rats with diabetes were further divided into two subgroups such as diabetes and diabetes+Liraglutide groups.

Buildup of reactive oxygen species during testicular torsion causes oxidative stress and ischemia-reperfusion (I/R) injury in testis. The purpose of this study was to investigate influence of β-cryptoxanthin (BCX) on I/R injury in testicular torsion/detorsion in mature rats. Thirty mature male Wistar rats were divided into five groups of six animals each, including sham group: In this group, midline incision of the scrotum was performed and the testicles were taken out for 2 hr with a 720-degree rotation, I/R group: In this group, midline incision of the scrotum was performed and the testicles were taken out and undergone ischemia for 2 hr with a 720-degree rotation, I/R/Oil group: In this group, a midline scrotum cut was performed, the testicles were taken out, ischemia was created for 2 hr with a 720-degree rotation, and at the end of ischemia 100 µL of corn oil (BCX solvent) was injected intraperitoneally, I/R/BCX10 group: The same as I/R/Oil group, as well as intraperitoneal administration of 100 µL of BCX (10.
