Erectile dysfunction is defined as the inability to attain and maintain penile rigidity sufficient to allow sexual intercourse. Although erectile dysfunction is usually considered a benign disorder, it has a dramatic impact on quality of life of the patients as well as their sexual partners. And it is common in men between the age of 40 and 70 years, and its incidence increases with age. The prevalence is reported to occupy 10% at the age of 40 years, 20% in 50s, 30% in 60s and 50% at the age of 70 years, and is more prevalent as stress in modern life and interest onsexual behavior increase. This article has aims to investigate and summarize the current trend of treatment for erectiledysfunction so as to suggest the effective and available way to treat the disease. In oriental medicine, erectile dysfunction has been treated with herb medicine and acupuncture with good results. Some of herb drugs have the substances which induce penile erection. So it should be investigated on the neurotransmitter or endothelial mediator which can be included in herb drugs. The acupuncture therapy stimulates the erectile nerves and is reported to be effective for erectile dysfunction. And suppository, locus injection therapy and topical agent are found to be effective as well as stellate ganglion block and biofeedback treatment. So the study on the approach and application of these treatments on erectile dysfunction would be necessary.

The neurotropic psudorabies virus(PRV) to replicate within neurons is very useful pathogen for neuronal tracing. I carried out this study to investigate the parametric analysis on the viral infection in the rat circadian control center with two genetically engineered strains out of PRV. The two strains are isogenic with the attenuated Bartha strain of PRV ; in one strain a lacZ reporter gene was inserted into the gC locus (PRV-BaBlu ; $4.75\times10^8pfu/ml$) and the other strain contained a PRV envelope glycoprotein gene(PRV-D ; $2.5\times10^8pfu/ml$) theat is absent in PRV-BaBlu. simultaneous or temporally separated sequential injection of$2{\mu}l$ of each strain into the vetreous body of eye produced a course of transsynaptic infection of retinohypothalamic circuitry. The results were as follows; 1. PRV-BaBlu and PRV-D infected the suprachiasmatic nucleus in hypothalamus and intergeniculate leaflet in lateral geniculate nucleus of thalamus. 2. The rate of PRV infection was dependent upon PRV strain. 3. Pre-infected neurons by PRV-D were interfered with the replication of PRV-BaBlu. 4. Dual injection of PRV-D and PRV-BaBlu showed more virulent than the parental strain.

The ability of neurotropic alpha herpesviruses to replicate within synaptically linked neurons has made these pathogens valuable tools for transneuronal analysis. Recent studies suggest that unique gene products expressed by genetically engineered strains of virus may permit the use of multiple strains in complex tracing paradigms. In the present study we have examined the invasiveness of two genetically engineered strains of the swine pathogen known as pseudorabies virus(PRV). The two strains were isogenic with the attenuated Bartha strain of PRV; in one strain a lacZ reporter gene was inserted into the gC locus (PRV-BaBlu; $4.75\times10^8pfu/ml$) contrained a PRV envelope glycoprotein gene that was absent in PRV-BaBlu. Simultaneous or temporally separated sequential injection of $4\mu\ell$ of each strain into the ventral wall of the stomach produced a predictale course of retrograde synaptic infection. The results were as follows: 1. PRV-BaBlu and PRV-D infected the dorsal motor nucleus of vagus nerve(DMV) and paraventricular nucleus(PVN). 2. Invasion and replication of PRV-D occured at a faster rate than the parental strain or PRV-BaBlu. 3. PRV-D was much more virulent than PRV-BaBlu or the parental strain. 4. Co-injection of PRV-D and PRV-BaBlu produced an infection that was more virulent than that produced by the parental strain (PRV-Bartha), 5. Neurons in DMV were permissive to co-infection with PRV-D and PRV-BaBlu when they were injected simultaneously into the same site. 6. Replication of PRV-BaBlu was compromised by prior infection of the same circuit with PRV-D. 7. Prior infection of neurons with PRV-D maked them resistant to infection with PRV-BaBlu.

Benign Prostatic Hyperplasia(BPH) is the most common benign tumor seen in the western male, and it is found in 50% of men over 50 years of age. It is characterized by the formation of large discrete lesions in the periurethral region. As they enlarge, these nodules tend to compress the urethra and cause partial or almost complete obstruction of .urine flow. The etiology of BPH is uncertain, but the increasing incidence with advancing age suggests the possibility of an imbalance between male and female sex hormones. In the past, most patients have had multiple indications to support the decision to initiate therapy. But both the urologic surgeon and the patient must be clearly aware of the results that can be expected and the risks involved in achieving them. The aims of this study are to investigate and summarize the current trends of treatment for BPH so as to suggest the effective and available way to treat the disease. In Oriental medicine, the BPH is recognized as uroschesis and ischuria, and the etiology is mainly in stagnated blood and insufficiency of the kidneys. The point of treatment of BPH is recovery of urination, and the treatment can be approached in two ways through herb drugs and acupuncture. Some of the herb drugs have substances which reduce BPB. Acupuncture therapy stimulates the pelvic plexus and is reported to be effective for voiding. Suppository, massotherapy, rectal injection, locus injection and attachment of herb drugs to the navel or the acupoint are announced as the effective treatments. So, this study of the approach and application of these treatments on BPH would be necessary.
