    Introduction: Reducing pain and enhancement of wound healing have several advantages. Wound healing is a complicated but regular process that includes synchronized and organized phenomena such as paranchyma cells migration, proliferation and synthesis of extracellular matrix proteins. Rate of wound healing is affected by various factors. The aim of our study was to investigate the effects of low power He-Ne laser radiation (630 nm), on metabolic process, cellular proliferation and finally wound repairment.
 Methods: In our research, about 50 healthy and mature rats were studied by experimental method. After shaving, small cuts (10 mm) were made at the neck. Then they were divided randomly into control and case groups. The rats of the case group were radiated by He-Ne laser in the wounds about 4 minutes each day. After a week, we did wound autopsy of both groups and all the specimens were studied microscopically.
 Results: The findings showed that there were significant increase in the fibroblasts and connective tissue fibers and also vascularisation in the case group compared with the control group.
 Discussion: Wound healing in the case group was accelerated and wound diameter was smaller significantly. So, low power He-Ne laser radiation accelerates wound healing process

    Testicular torsion-detorsion results in enhanced formation of free radicals which contribute to the pathophysiology of testicular tissue damage. Recent reports have identified protective role of pentoxifylline (PTX) against free radicals. Thus, we determined the protective effect of pentoxifylline against testicular damage in mouse model of testicular torsion-detorsion. Twenty (6 weeks old) male mice were divided into 4 groups of 5 animals each namely: Control (sham operated group), T1 (Torsion-detosion + single dose 100 mg/kg PTX, T2 (torsion-detorsion + 20 mg/kg PTX for 2 weeks and T/D (torsion-detorsion only). Animals in T1, T2 and T/D groups underwent 2 h of testicular torsion with the left testes rotated 720° (clockwisely) followed by 30 min of detorsion. After detorsion, drug administration was done intraperitoneally. The left testes of all the animals were excised on the 35th day after torsion-detortion for histopathological and biochemical assay. Histomorphological analysis of the seminiferous tubules showed that there were significant increase (P 0.05) in testes weight, sertoli, leydig and myoid cells in all groups. IHC results showed significant increase (P < 0.01 or 0.05) in id4 and scp3 protein markers in Control, T1 and T2 compared to T/D. Oxidative stress analysis revealed that Pentoxifylline significantly increased (P < 0.01 or 0.05) the level of SOD, catalase, mRNA expression of akt and pi3k genes but significantly suppress (P < 0.01 or 0.05) MDA and Caspase-3 level in Control, T1 and T2 compared to T/D. Pentoxifylline could be used as an adjunct therapy to surgery in the treatment of torsion-detorsion related testicular injury, However, Further studies are needed to evaluate the effects of pentoxifylline on testicular torsion. © 202
