  • Objective : This study was undertaken for discovering the characteristics of sleep in ordinary symptoms based on the Sasang Constitution. The result of this study could be helpful to understand and to identify patients such as Taeumin, Soyangin Soeumin or Taeyangin. Methods : There were 1,229 patients (529 men), who answered the questionnaire about their ordinary sleeping patterns. They were diagnosed, including their clinical Sasang Constitution, by the Sasang Constitution specialist at Bundang Oriental Hospital of Dongguk University. By applying the multinomial and binary logistic regression analysis to those collected materials, we can measure the characteristics and the influence of ordinary sleeping patterns to the dependent variable (Sasang Constitution). Results : In order of the item's influence that had decided one's constitution, between Taeumin and Soeumin, Taeumin snored frequently or well more than Soeumin, Soeumin had more dreams and more sleeping times than Taeumin, and Taeumin struggled frequently or well more than Soeumin. Between Soyangin and Soeumin, Soeumin dreams more frequently than Soyangin, Soyangin snored frequently or well more than Soeumin, and Soeumin has more sleeping times than Taeumin. Between Taeumin and Soyangin, Taeumin snored frequently or well more than Soyangin. Between Taeyangin and a group of the other constitutions, Taeyangin felt unwell after sleeping more than the other constitutions, the other constitutions awaked frequently more than Taeyangin during sleeping. Conclusion : This study will be used for identifying patients as Taeumin, Soyangin, Soeumin or Taeyangin by contrast with each other.

  • Transcriptional activation domain (TAD) in virion protein 16 (VP16) of herpes simplex virus does not have any globular structure, yet exhibits a potent transcriptional activity. In order to probe the structural basis for the transcriptional activity of VP16 TAD, we have used NMR spectroscopy to investigate its detailed structural features. Results show that an unbound VP16 TAD is not merely "unstructured" but contains four short motifs (residues 424-433, 442-446, 465-467 and 472-479) with transient structural order. Pre-structured motifs in other intrinsically unfolded proteins (IUPs) were shown to be critically involved in target protein binding. The 472-479 motif was previously shown to bind to $hTAF_{II}31$, whereas the $hTAF_{II}31$-binding ability of other motifs found in this study has not been addressed. The VP16 TAD represents another IUP whose pre-structured motifs mediate promiscuous binding to various target proteins.

  • Objective : In order to find antiviral compounds against Herpes simplex virus type I(HSV-1) and II(HSV-2) from herb medicines, a convenient virus-induced cytopathic effect(CPE) inhibition assay was introduced. Methods : Fourteen purchased herbal medicines, and their toxicity of infected cell and anti-viral activities were evaluated. Among them, the major part of herbal medicines showed cell stability compared with the contrast. Results : Cytotoxic concentration (CC) of the $H_2O$ extracts of Hyongbangpaedoksan against HSV-1 and HSV-2 was 181.12. This is high level cytotoxic concentration compared with the contrast. Therefore, we assumed that the high level cytotoxic concentration of herbal medicine play a major role in improvement of antiviral activity at the first infective cell. But antiviral effect was unable to figure out for selective index(Sl)=CC50/EC50. The other herbal medicines were unable to showed potent anti-HSV activity. Conclusions : The antiviral activation using herbs in this thesis have unlimited objects, to select research object will help to show the direction of antiviral drug development that have less side effect and more excellent efficiency.

  • In order to find less toxic antiherpetic agents, the effect of natural quercetin on the plaque formation of herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) was studied in vitro in cell culture monolayers employing the technique of viral plaque reduction assay. Quercetin caused a concentration-dependent reduction in the plaque formation of herpesviruses. It also exhibited more potent antiherpetic activity on HSV-1 with effective concentration $(EC_{50})$ of $18.7\;{\mu}g/ml$ than on HSV-2 with $EC_{50}$ of $24.5\;{\mu}g/ml$. The combined antiherpetic effects of quercetin with nucleoside antiherpetic agents, acyclovir and vidarabine, were examined on the multiplication of these two strains of herpesviruses in Vero cells by the combination assay. The results of combination assay were evaluated by the combination index (CI) that was calculated by the multiple drug effect analysis. The combinations of quercetin with acyclovir on HSV-1 and HSV-2 showed more potent synergism with CI values of $0.19{\sim}0.89$ for 50%, 70%, 90% effective levels than those with vidarabine with CI values of $0.43{\sim}1.46$.

  • We have previously reported that simulated snuff dipping in conjunction with type I herpes simplex virus (HSV-1) induced oral malignant changes in hamsters. Present study was designed to investigate the carcinogenic effect of tobacco specific-N-nitrosamines (TSNAs) and HSV-1, alone or in combination, in hamsters. Hamsters were divided into 6 groups and the right buccal pouch mucosa were treated as follows: Grp 1, Control (Mock inoculation) [MI]+Topical Application [TA] of mineral oil[MO] : Grp 2, TA of 1% n'- nitrosonornicotine [NNN] + IM: Grp3, TA of 1% 4-N-nitrosomethylamino-1- (3-pyridyl)-1-butanone [NNK] + MI: Grp 4, HSV-1 inoculation [HI]+TA of MO : Grp 5, TA of 1% N-nitrosonornicotine [NNN] + HI: Grp 6, TA of 1% NNK + HI. TA of MO or TSNAs was initiated 1 day after the MI or HI and given 3 times per week for 20 consecutive weeks. At the buccal pouches were fixed for light microscope examination. No animal s developed tumors or malignant histopathologic changes in the mucosa of the buccal pouches. These data indicate that individual TSNAs, alone or in conjunction with HSV-1 infection, do not develop malignant changes in hamster buccal pouches.

  • Postherpetic neuralgia (PHN) is defined as the persistence of pain after recovery from herpes zoster (HZ), when the rash has healed, usually after about 4 weeks. PHN is the most feared complication of herpes zoster and remains one of the most common and intractable chronic pain disorders. Recent evidence has shed some light on the possible mechanism of pain, and on the prophylactic and treatment approaches to PHN, but there is no secure therapy. This report is a case of a 70-year-old male with PHN, affecting the 8th to 10th thoracic dermatomes. Patient complains of allodynia and hyperalgesia on the affected skins. After sympathectomy, antidepressant, anticonvulsant, and capsaicin ointment application, much pain relief was achieved, but allodynia remained at the subcostal area about $7\times3 cm^2$ in size. We decided to remove the painful area. Skin excision was done under local anesthesia. After skin excision, the pain was decreased and patient did not complain of pain for 10 months.

  • GLPG (Ganoderma lucidum proteoglycan) was a bioactive fraction obtained by the liquid fermentation of the mycelia of Ganoderma lucidum, EtOH precipitation, and DEAE-cellulose column chromatography. GLPG was a proteoglycan with a carbohydrate: protein ratio of 10.4: 1. Its antiviral activities against herpes simplex virus type 1 (HSV-1) and type 2 (HSV-2) were investigated using a cytopathic inhibition assay. GLPG inhibited cell death in a dose-dependent manner in HSV-infected cells. In addition, it had no cytotoxic effect even at 2 mg/ml. In order to study the mode of action of the antiviral activity of GLPG, cells were treated with GLPG before, during, and after infection, and viral titer in the supernatant of cell culture 48 h post-infection was determined using a $TCID_{50}$ assay. The antiviral effects of GLPG were more remarkable before viral treatment than after treatment. Although the precise mechanism has yet to be defined, our work suggests that GLPG inhibits viral replication by interfering with the early events of viral adsorption and entry into target cells. Thus, this proteoglycan appears to be a candidate anti-HSV agent.

  • We have investigated the biochemical properties of the herpes simplex virus type 1 (HSV-1) DNA polymerase without the UL42 protein (Pol), purified from insect cells infected with a recombinant baculovirus containing the UL30 gene. BSA and DTT have inhibitory effects on dAMP incorporation. Pol showed a greater turnover rate of steady-state single nucleotide incorporation at 12 mM $MgCl_2$ than at 2 mM $MgCl_2$. However, it showed a greater processivity of DNA synthesis at lower $MgCl_2$ concentration (1 mM, 2 mM) than at a higher $MgCl_2$ concentration (12.5 mM). These results are consistent with a slow DNA dissociation at lower $MgCl_2$ concentrations. Pol does not incorporate a correct nucleotide into the primer with an incorrect nucleotide at the end; instead, it preferentially excises the incorrect nucleotide at the 3' end of the primer. Pol has DNA polymerase activity at pHs 6.5 and 7.5 but little at pHs 5.5, 8.5, and 9.5. It has exonuclease activity at pHs 6.5, 7.5, and 8.5 but little at pHs 4.5, 5.5, and 9.5. The finding that Pol has exonuclease activity but not DNA polymerase at pH 8.5 suggests that DNA binds to Pol, but deoxynucleotide binding or incorporation does not occur at pH 8.5.

  • Zoster sine herpete (ZSH) is a varicella zoster virus (VZV) reactivation without a zoster that is difficult to diagnose early after onset. This study examined 12 patients who presented with intercostal neuralgia, had no history of trauma, cutaneous eruption and no scar of a herpes zoster on the lesion. Two patients had a vertebral compression fracture. Two patients had a history of a zoster in the other site. No other suspicious findings were observed. Ten of the twelve patients were checked for the IgG and IgM varicellar zoster virus antibody. All the patients tested positive to the Ig G antibody test and only one patient tested positive to the IgM antibody test. One patient was confirmed to have ZSH and the other patients were suspected of having ZSH. All the patients were treated for postherpetic neuralgia, resulting in a significant decrease in the intercostal neuralgia.
