Aim: This study aims to analyze the effect of dapsone against ischaemia-reperfusion injury on corporal tissue in a model of induced-priapism in rats. Material and Method: A total of 24 rats were randomized into three groups. Group 1 was defined as the control group. Ischaemia-reperfusion injury was evaluated following the priapism model in Group 2. Group 3 had similar procedures to the rats in Group 2. Group 3 additionally had 12.5 mg/kg dapsone administered intraperitoneally 30 minutes after priapism. Results: Biochemical analysis of blood indicated a significant increase in Group 3 in terms of superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) activity and total antioxidant status (TAS) values compared with Group 2 (p:0.002, p:0.029 and p:0.009, respectively). The highest values of malondialdehyde (MDA), protein carbonyl (PC) and total oxidant status (TOS) were recorded in Group 2 (p<0.001). Interleukin 1beta (IL-1beta), Interleukin 6 (IL-6) and tumor necrosis factor alpha (TNF alpha) levels were found to be significantly decreased in Group 3 compared with Group 2 (p:0.022, p:0.049 and p<0.001, respectively). Direct microscopic evaluation determined an improvement in inflammation, edema, desquamation and vasocongestion scores in Group 3 compared to Group 2 (p<0.05). Conclusion: Dapsone has a protective effect on ischaemia-reperfusion injury in corporal tissue.

Milrinone ameliorates ischaemia-reperfusion injury in experimental testicular torsion/detorsion rat model
(Andrologia, 2021) Unsal, Velid; Kölükçü, Engin; Atılgan, Doğan; Uluocak, Nihat; Deresoy, Faik Alev; Katar, Muzaffer
This experimental study aims to evaluate the efficacy of milrinone against ischaemia-reperfusion injury due to testicular torsion/detorsion. Group 1 was defined as the control group. Testicular torsion/detorsion model was performed in Group 2. Group 3 had similar procedures to the rats in Group 2. In addition, 0.5 mg/kg of milrinone was administered intraperitoneally immediately after testicular torsion in Group 3. Histopathological examinations indicated a dramatic improvement in terms of inflammation, haemorrhage, oedema, congestion, Cosentino and Johnson scores in Group 3 compared to Group 2 (p =.037, p =.045, p =.018, p =.040, p =.033 and p =.03 respectively). Blood biochemical analyses, superoxide dismutase (SOD), glutathione peroxidase (GSH-px) activity and total antioxidant status (TAS) levels increased significantly in Group 3 compared to Group 2 (p =.001, p =.024 and p <.001). Malondialdehyde (MDA), protein carbonyl (PC), interleukin 1beta (IL-1beta), tumour necrosis factor-alpha (TNF-alpha) and total oxidant status (TOS) levels decreased in Group 3 compared to Group 2 (p =.001, p =.018, p <.001, p =.036 and p =.002 respectively). Tissue biochemical analyses determined an increase in SOD and GSH-px activity in Group 3 compared to Group 2, while PC and MDA levels were reduced (p =.001, p <.001, p =.038 and p <.001 respectively). Milrinone attenuates ischaemia-reperfusion injury that causes highly harmful effects due to testicular torsion/detorsion.
