Penile amputation results primarily from attempts at self-emasculation in the psychotic individual or from felonious assault. Because of the complex nature of patients whom perform self-emasculation and low incidence of felonious assault, large series of these individuals do not exist, and experience with amputation injuries of the genitals is confined to individual case reports. Fortunately, complete amputation of penis is quite rare but potentially devastating occurrence. The repels of the treatment of penile amputation by coporal reapproximation that have been published since 1977 indicate that microreplantation techniques are propably superior to the technically simpler nonmicroscopic coporal reapproximation techniques. As microsurgical techniques have been demonstrated to superior, the preferred method of replantation involves this routine whenever possible. We have experience of a case of successful replantation of completely amputated penis by using microneurovascular repair, with the good result of cosmetic and functional concern. Herein, we report this case with the review of the literatures.

Objective : This study investigated the effects of Yangsaengwhallyukdan on nitrite oxide synthase (NOS) activity, nitrite level, antioxidation and erectile response in rat corpus cavernosum penis. Methods : Yangsaengwhallyukdan was formulated to contain various natural products that have been used to treat erectile dysfunction. Yangsaengwhallyukdan suspended in a 0.5% CMC solution was oral-administered, 50 mg or 100 mg per 1 kg of body weight for 30 days, while the normal group was administered only with a 0.5% CMC solution. The efficacy of the Yangsaengwhallyukdan was assessed with regard to erectile function. Results: After the Yangsaengwhallyukdan was administered to the rat for 30 days, the urethral NOS activity increased. The level of urethral nitrite, glutathione and testosterone increased too. The level of urethral lipid peroxide was decreased in Yangsaengwhallyukdan treated rats. The erectile response to a cavernous nerve stimulation in L-NAME$(10^4)$-treated rats in rats given Yangsaengwhallyukdan reached the level of the normal group. Conclusions : This study suggest that Yangsaengwhallyukdan is effective for the treatment of erectile dysfunction.

The aim of this study was to evaluate the mechanism of vasodilation of Lespedezea cuneata(LC) in rabbit common carotid artery and cavernosal smooth muscle. LC relaxed arterial strips precontracted with norepinephrine and cavernosal strips precontracted with phenylephrine. The arterial relaxation effects of LC was endothelium-dependent. $N{\omega}$-nitro-L-arginine(L-NNA), NOS inhibitor, methylene blue(MB), cGMP inhibitor, indomethacin(IM), cyclo-oxygenase inhibitor and tetraethylammonium chloride(TEA), KCa-channel blocker attenuate the relaxation responses of LC in arterial strips. In $Ca^{2+}$-free krebs-ringer solution, pretreatment of LC extract significantly reduced the contraction induced by addition $Ca^{2+}$. L-NNA reduced LC extract-induced relaxation in cavernosal strips, but IM, TEA and MB didn't affect LC extract-induced relaxation. When LC extract was applicated on human umbilical vein endothelial cell, the nitric oxide concentration was increased. We conclude that in rabbit common carotid artery, LC may suppress influx of extra-cellular $Ca^{2+}$ through the release of endothelium derived relaxing factor including nitric oxide, prostacyclin, endothelium derived hyperpolarizing factor. And LC exerts a relaxing effect on corpus cavernosum through activating the NO.

Biophotons from three healthy subject's hands were measured every Friday for one year. The correlation coefficients between the left and right palms were found to be 9.0, and a similar value was also obtained between the left and right back of hands. However, the correlations between the palm and back of a hand turned out to be low, on the average only 0.5. These results are consistent with the result of Zhang's $CO_2$ production rate experiments on the acupuncture points. The high correlation between the left and right, and the low correlation between the palm and back are interpreted according to the acupuncture theory of meridians. The palm and the back correspond to the yin and yang meridians, respectively. And their behaviors are rather opposite, thus they show low correlations.

Purpose: To report a rare case of concealed penis that was aggravated by circumcision and simple way of treatment using skin flap. The concealed penis is a primarily pediatric disease and is usually treated by urologists. The plastic surgeons tend to see these patients when it become secondary deformation or in conjoinment with other specialties. In such situation, the plastic surgeons do not have many experiences. Methods: A 3-year-old boy was admitted with aggravated concealed penis after circumcision in congenital webbed penis. Patient had been operated with scar revision and skin flap and peri operative antibiotics. Results: The patient recovered well without any complication such as infection, hematoma and necrosis of flap. Patient was discharged POD#7 with remaining sutures. Patient was followed up for 7 months and he has no sign of erectile dysfunction, voiding dysfunction and evidence of inflammation of the urinary system. Conclusion: We experienced a case of concealed penis that was aggravated from aggressive circumcision in congenital webbed penis.

Rosae laevigatae Fructus extract (RLF) was tested for the effects on the urethral nitric oxide synthase (NOS) activity and Antioxidation in streptozotocin (STZ) induced diabetic rats. RLF was treated firstly into samples, and then STZ induced diabetic rats were set with them. In vitro, the urethral NOS activity was not noted but the type O activity and type conversion ratio of xanthine oxidase and the level of urethral lipid peroxide were decreased in the level of Dose of extract prepared from RLF. In vivo, after the extract was administered to the animal model for fifteen days, the urethral NOS activity increased in STZ induced diabetic rats to the level of normal rats. The content of urethral nitrite and glutathione followed by RLF pre-medicating administration, increased as highly as normal group in compare with the group treated with STZ. The type O activity and type conversion ratio of xanthine oxidase and the level of urethral lipid peroxide followed by RLF pre-medicating administration, decreased as lowly as normal group in compare with the group treated with STZ. In conclusion, the extract of RLF will be able to restore erectile dysfunction of STZ induced diabetic rats.

In order to define the effect of Torilis Fructus(TF) extract which has been used for the treatment of erectile dysfunction, experiments were carried out by organ bath study, histochemical and immunohistochemical methods. First, in the organ bath study, when TF extract was administered to the maxillary contracted corpus cavernosum by PE ($10^{-6}M$), there was a significant relaxation effect on corpus cavernosum at concentration of 1, $3mg/m{\ell}$. Compared with the absence of $\text\tiny{L}$-NNA pretreatmen, pretreatment of $\text\tiny{L}$-NNA was inhibited the relaxation effect of penile corpus cavernosum. In the immunohistochemical study, the eNOS positive reaction was significantly increased, and the PDE5 positive reaction was significantly decreased due to the administration of TF extract. Therefore, it show that the TF enhances the production of eNOS and NO, inhibits PDE5 which blocks the action of increased cGMP, relaxes the corpus cavernosum. So TF relaxes the corpus cavernosum and it can be used as a safer erectile dysfunction treatment.

Neuroablation should be performed cautiously because neuropathic pain can occur following denervation of a somatic nerve. A 34-year-old man presented with severe penile pain and allodynia following a selective neurectomy of the sensory nerve that innervated the glans penis for treatment of his premature ejaculation. He was treated with various nerve blocks, including continuous epidural infusion, lumbar sympathetic block and sacral selective transforaminal epidural blocks, as well as intravenous ketamine therapy. However, all of the treatments had little effect on the relief of his pain. We performed spinal cord stimulation as the next therapy. After this therapy, the patient has currently been satisfied for 3 months.

This study was aimed to investigate the relaxation effects of Eucomiae Cortex (EC) extract in isolated rabbit corpus cavernosum smooth muscle and its mechanism. To evaluate the relaxation of EC extract in rabbit corpus cavernosum, EC extract was treated in corporal strips which were precontracted with phenylephrine(PE). To study its mechanism, Nω-nitro-L-arginine (L-NNA) was pretreated after infuse of EC extract and compared with non-treated. In calcium chloride (Ca²⁺) -free krebs solution, EC extract and Ca²⁺ 1 mM were infused by turns after Ca²⁺ 1 mM was treated into corporal strips contracted by PE. Cell ability, nitric oxide (NO) and epithelial nitric oxide synthase (eNOS) on human umbilical vein endothelial cell (HUVEC) were measured by MTT assay, Griess reagent system and histochemical, immunohistochemical methods. EC extract showed a significant relaxation effects on the corporal strips, this effects were inhibited by pretreatment of L-NNA. EC extract inhibited the increase of contraction by Ca²⁺ influx in Ca²⁺-free krebs solution, and eNOS positive reaction in corpus cavernosum, NO production in HUVEC increased by treatment of EC extract. These result suggest that the relaxation effects of EC extract in isolated corpus cavernosum smooth muscle are involved in increase of eNOS and NO production, blocking of extracellular Ca²⁺ influx.
