Purpose: The purpose of this study was to identify sexual activities of males with spinal cord injury (SCI) and influential factors of sexual adjustment. Methods: A correlational survey was conducted among a total of 135 males with SCI. Results: After SCI, patients maintained low levels of sexual adjustment, and a main obstacle of sexual rehabilitation was decreased erectile function (65.2%). Sexual desires recovered in 84.4%, with 62.4% patients reporting more than once intercourse experiences. The erectile function of participants with normal, decreased or no erectile function were 13.0%, 62.6% and 24.4%, respectively. 8.1% of the participants reported no problem with ejaculation. Patients with incomplete SCI had better preserved erectile function than those with complete SCI (t=-4.627, p<.001). Patients with upper motor neuron injury had better preserved erectile function than those with lower motor neuron injury (t=2.446, p =.016). Sexual adjustment was relevant to age, job, degree of injury, post-injury period, sexual desire, intercourse experience, erection therapy, erectile function, and sexual health. Sexual adjustment was a factor of sexual health with a power of 24.2%. Conclusion: The main obstacle of sexual rehabilitation for males with SCI decreased erectile function. Erection and ejaculation are dependent on the severity and level of SCI. The major influence on sexual adjustment is sexual health.

발기부전 환자에서 홍삼의 효능을 객관적으로 확인하기 위하여 홍삼 복용 전후의 음경혈류 변화를 AVS-Penogram을 이용하여 홍삼이 음경발기 및 음경혈류에 미치는 영향을 활성도 곡선의 유형 변화와 최대활성도치를 분석하여 평가하고, 동시에 주관적인 발기부전의 증상호전 정도를 비교하였다. 활성도 곡선유형은 홍삼 투여군에서 위약 투여군에 비하여 전반적으로 호전 양상을 보였으나 통계학적 유의성은 없었고, 최대활성도치의 증가에서는 홍삼 투여군이 57.9%(l1/19)로 위약 투여군의 22.2%(2/9)에 비하여 유의하게 높은 호전을 보였으며, 주관적인 증상호전에서도 홍삼 투여군이 63.2％(12/19)로 위약 투여군의 33.3%(3/9)에 비하여 유의한 호전을 나타냈다. 약물의 안정성 평가에서는 약물 관련 특이 반응이나 특별한 부작용은 없는 것으로 나타났다. 이상으로 발기부전 환자에서 홍삼의 투여가 특별한 독성이나 부작용 없이 위약군에 비하여 좋은 치료효과를 보이며, 음경발기와 음경혈류 증가에 양성적인 영향을 미치는 것으로 나타났으며, 단독 투여뿐만 아니라 다른 발기부전 치료제와의 병용 요법에 따른 상승효과(synergic effect) 등에 대하여도 인상 연구가 필요하리라 생각된다.

Objectives : This study was designed to investigate effects of the combination with Korean Red Ginseng (Panax ginseng C.A. Meyer), Gastrodia Rhizoma (Gastrodia elata Blume) and Polygoni Multiflori Radix (Polygonum multiflorum Thunberg) on metabolic disorders including cholesterol and erectile dysfunction in hyperlipidemia rats.Methods : Animals were divided into six groups; Control with normal diet, high fat/cholesterol-diet (HFCD), fluvastatin, Korean Red Ginseng treated (KRG), and the combination treated (Korean Red Ginseng, Gastrodia Rhizoma and Polygoni Multiflori Radix; 1:1:1 for KGP1 and 2:1:1 for KGP2). The experimental groups initially received HFCD for 10 weeks and then treated orally with fluvastatin, KRG, KGP1 and KGP2 during the final 6 weeks. Erectile function was determined by the measurements of intracavernosal pressure (ICP) and maximal arterial pressure (MAP) after electrical stimulation of the cavernosal nerve.Results : KGP2 decreased the level of total cholesterol and LDL cholesterol in the sera of HFCD rats without no changes of body weights. KRG, KGP1 and KGP2 decreased the level of C-reactive protein (CRP) levels except of fluvastatin, synthetic HMG-CoA reductase inhibitor. KRG, KGP1 and KGP2 significantly increased the ICP, ICP/MAP ratio, area under the curve (AUC) compared with those of normal rat. Morphometric analyses showed that KRG, KGP1 and KGP2 increased the volume of smooth muscle and the regular arrangement of collagen fibers in corpus cavernosum of HFCD rats. The penile expression of eNOS was increased by KRG, KGP1 and KGP2.Conclusions : Based on these results, we suggest that the combination with Korean Red Ginseng, Gastrodia Rhizoma and Polygoni Multiflori may improve hyperlipidemia through regulating the lipid profiles and erectile dysfunction in rats.

The emergence of phosphodiesterase (PDE) 5 inhibitors gave rise to the solution for erectile dysfunction, starting with the development of sildenafil. Although their efficacy in treating erectile dysfunction has been shown, the side effects of PDE5 inhibitors, especially sildenafil, must be taken into consideration. A 64-year-old man received 100 mg of sildenafil and experienced blue vision in both eyes; however, after a day or so, his symptoms improved. The symptoms disappeared when he stopped administering sildenafil, but reappeared when the medication was re-administered. Therefore, he discontinued sildenafil treatment and was prescribed udenafil instead. After that, visual adverse events no longer occurred. Causality assessment showed that in this case, sildenafil-induced cyanopsia was "certain" under the World Health Organization-Uppsala Monitoring Center (WHO-UMC) criteria and Korean causality assessment algorithm (Ver.2), and was "probable" according to the Naranjo scale. In addition, sildenafil also led to abnormal visual reactions in other cases. Sildenafil can also inhibit PDE6, which is present in retinal cells, unlike other PDE5 inhibitors. Thus, visual adverse reactions, such as blue vision, are the unique results of sildenafil, and other PDE5 inhibitors may be used to prevent them.

[ $PGE_1$ ] is an endogenous substance of potent vasodialator as well as inhibitor of platelet aggregation. It has been used therapeutically in peripheral arterial occlusive disease and impotence. Intracavernous injection of $PGE_1$ for erectile dysfunction has been established for several years as a treatment option for erectile dysfunction of diverse etiologies, but this mode of administration is limited by penile discomfort, pain at the injection site, inconvenience and noncompliance. As the matter of worse, the $\beta-hydroxy$ moiety of $PGE_1$ is extremely susceptible to dehydration in solution to give inactive $PGA_1$ and $PGB_1$. For the improvement of stability, rapid absorption at action site and the convenience of application, $PGE_1$ was formulated as urethral suppositories of three types of formulations, such as PEG, witepsol, and the mixture of PEG and witepsol. The stability test of $PGE_1$ and the release test in urinary suppositories were performed. Futhermore, the effect of enhancers and vehicle composition on the penetration of $PGE_1$ through excised rat skin was evaluated by permeability coefficient and enhancement ratio.

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.
