Purpose: Gene therapy, stem cell therapy, and low-energy extracorporeal shockwave therapy (ESWT) have been investigated as treatments for refractory erectile dysfunction (ED), but inconclusive evidence has been obtained. We investigated the effect of a next-generation electromagnetic cylinder ESWT device on an animal model of ED.Materials and Methods: Diabetes mellitus (DM)-induced rats were divided into 3 groups: group 1, control; group 2, DM; and group 3, DM+ESWT. Rats were treated with ESWT 3 times a week for 2 weeks. After the treatment course, intracavernous pressure was measured and the corpus cavernosum and cavernous nerve were evaluated.Results: In the DM group, all parameters predicted to be significantly lower in the ED model had statistically significantly decreased (p<0.01). As a measurement of erectile function, intracavernous pressure was evaluated. The DM+ESWT group exhibited significantly restored erectile function compared to the DM group (p<0.05). Moreover, ESWT treatment restored smooth muscle content, as assessed by Masson’s trichrome staining (p<0.05). Finally, corporal tissue and the dorsal nerve were evaluated by immunohistochemistry, Western blotting, and ELISA. After ESWT treatment, vascular endothelial growth factor (VEGF), endothelial nitric oxide synthase (eNOS), platelet endothelial cell adhesion molecule-1, cyclic guanosine monophosphate, and neuronal nitric oxide synthase (nNOS) expression levels were restored to levels in the DM group (p<0.05).Conclusions: Electromagnetic cylinder ESWT device resulted in increased VEGF, nNOS, and eNOS expression; reduced smooth muscle atrophy; and increased endothelial cell regeneration in a DM-associated ED model. Our data suggest that safe and effective application could be possible in future clinical studies.

<P>The Korean herbal formulation Ojayeonjonghwan is used for improving late-onset hypogonadism (LOH) symptoms such as erectile dysfunction (ED). A previous research suggested that a modified Ojayeonjonghwan (KH-204) could be used as an alternative to the treatment for ED. The pharmacological effects were examined in different conditions, including in vitro and in vivo. We measured the survival rate of TM3 Leydig cells under the oxidative stress condition. The s.c. injection of leuprorelin was used to induce androgen deprivation. We measured serum testosterone levels, oxidative stress, and apoptosis. The results of the treatment by KH-204 (1) preserved TM3 cells from oxidative stress by improving the expression of nuclear factor erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1); (2) lowered the expression of transforming growth factor-beta (TGF-<I>β</I>) 1/SMAD; (3) increased the average of serum testosterone in androgen-deprived male rats; (4) kept the activation of spermatogenesis; (5) upgraded the contents of 8-hydroxy-20-deoxyguanosine (8-OHdG) and degraded the contents of superoxide dismutase (SOD); and (6) reduced apoptosis. We studied that KH-204 improved testicular dysfunction in LOH. It is likely, at least in part, to degrade oxidative stress through the Nrf2/HO-1 pathway. These findings may offer credible evidences for the use of new alternative therapies to treat LOH.</P>
