  • 저자들은 파파베린유도 음경발기촬영술이 발기부전 원인의 선별검사로서 유용한지를 알아보고자 정상인 12예와 제반검사에서 확진된 동맥성 발기부전 5예, 정맥성 발기부전 12예, 심인성 발기부전 11예, 혼합형 발기부전 8예 및 신경성 발기부전 19예를 대상으로 하여 파파베린의 국소 주사로 발기를 유도하고 $^{99m}Tc$-HSA를 정주하여 관심영역의 시간방사능곡선을 구한 다음 발기유발시간, 발기지속시간 및 정맥성 계수를 비교하였다. 동맥성 발기부전군에서 발기유발시간이 정상 대조군에 비해 지연되어 있었고, 정맥성 발기부전군에서는 정상대조군과 동맥성 발기부전군에 비하여 발기지속시간이 단축되었으며 정맥성계수는 더 낮았다. 심인성 발기부전군에서는 발기지속시간이 정상 대조군 및 동맥성 발기부전군에 비해 지연되어 있었다. 이상의 결과로 파파베린유도 음경발기촬영술은 동맥성과 정맥성 발기부전 뿐만 아니라 심인성 발기부전도 선별할 수 있는 좋은 검사법으로 생각되나 혼합형과 신경성 발기부전을 감별하지 못하는 단점이 있었다.

  • 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.

  • We examine the effect of Geiji-Bokryung-Hwan(GBH) on erectile function in a rat model of hypercholesterolemic erectile dysfunction. GBH, a drug preparation consisting of five herbs of Cinnamomi Ramulus (Geiji), Poria Cocos (Bokryun), Mountan Cortex Radicis (Mokdanpi), Paeoniae Radix (Jakyak), and Persicae Semen (Doin) is a traditional Korean herbal medicine that is widely used in the treatment of atherosclerosis-related disorders. In this study, 3-month-old Sprague-Dawley rats were used. The 6 rats control animals were fed a normal diet and the other 18 rats were fed 1% cholesterol diet for 3 months. After 1 months, GBH was added to the drinking water of the treatment group of 12 rats but not the cholesterol only group of 6 rats. Of the 12 rats 6 received 30 mg/kg per day (group 1) and 6 received 60 mg/kg per day (group 2) of GBH. At 3 months erectile function was evaluated with cavernous nerve electrostimulation in all animals. Penile tissues were collected for electron microscopy, and to perform Western blot for endothelial nitric oxide synthase (eNOS), neuronal nitric oxide synthase (nNOS), basic fibroblast growth factor (bFGF) and caveolin-1. Systemic arterial pressure was not significantly different between the animals that were fed the 1% cholesterol diet and the controls. Conversely erectile function was not impaired in the herbal medicine treated rats. Electron microscopy showed many caveolae with fingerlike processes in the cavernous smooth muscle and endothelial cell membranes in control and treated rats but not in the cholesterol only group of rats. Western blot showed differences among groups in protein expression for eNOS, nNOS, caveolin-1 and bFGF protein expression in penile tissue. Increased eNOS and nNOS protein expressions dy high cholesterol diet were significantly decreased in group 1 and group 2. Interestingly, caveolin-1 and bFGF protein expression was significantly higher in groups 1 and 2 than in the cholesterol only and control groups.

  • In recent times, the number of men with late-onset hypogonadism has increased, and interest on this topic has also increased. This study was conducted to investigate effects of the mixture extract of Fructus amomi Amari, Eucommiae cortex, Bombyx batryticatus on improve late-onset hypogonadism. The experimental subjects consisted of three groups: a control group consisting of 8-week-old male ICR mice that had undergone no treatment, an aging-elicited group (AE group) consisting of 50-week-old ICR male mice that had undergone no treatment, and a Mixed herbal extract treatment group (MT group) consisting of 50-week-old ICR male mice that had undergone the mixture extract of Fructus amomi Amari, Eucommiae cortex, Bombyx batryticatus treatment (0.1 g/kg/day) for 6 months. After the experiment, the mice from all the experimental groups were dissected, and they were analyzed through histochemical and immunohistochemical methods. The mixture extract of Fructus amomi Amari, Eucommiae cortex, Bombyx batryticatus reduces aging-induced cell damage and oxidative stress and increases the secretion of serotonin and B-endorphin in aged mice, and promotes spermatogenesis in seminiferous tubules and reduces apoptosis and oxidative stress, and increases androgen receptor, $17{\beta}-HSD$ and GnRH, increases the ratio of smooth muscle to collagen fibers in the corpus cavernosum, increases eNOS, decreases PDE-5 and oxidative stress in aged mice, so it improves depression, reproductive, sexual problems caused by Late-onset hypogonadism. the mixture extract of Fructus amomi Amari, Eucommiae cortex, Bombyx batryticatus inhibits the induction of osteoporosis by increasing decreased bone matrix distribution due to aging, increasing the activities of OPC and OPN, which are produced in osteoblasts, and decreasing RANKL, MMP-3 activity, increasing OPG activity. It also reduces muscle damage, oxidative stress, inflammation and apoptosis of muscle tissue, and increases Myo-D in the sartorius muscle of aged mice for improving muscle atrophy caused by by Late-onset hypogonadism.
