1.Analysis of the Transmission Route of Human Papillomavirus in Heterosexual Couples.
Korean Journal of Gynecologic Oncology and Colposcopy 1999;10(1):47-57
Carcinoma of the uterine cervix has been considered to be a sexually transmitted disease(STD) and at present time, particullary human papillomavirus (HPV) is considered as the most likely infectious causative agents of uterine cervical cancer. But less is known about the sexual transmission of HPV and the status of HPV infection of male partner. Therefore, screenng of couples for HPV is very important for understanding HPV infection as a sexually transmitted disease and prevention of cervical carcinoma. The polymerase chain reaction(PCR) was employed to detect HPV 16 and 18 in cytological samples from the uterine cervix of the patients with cervical carcinoma(4 CIS and 34 invasive cervical carcinoma) and from urethral metatus and glans sulcus of their male consorts. The results are as follows; 1. HPV 16 or 18 were detected in 31(81.6%) of 38 patients with cervical cancer(HPV 16; 78.9%(30/38), HPV 1S; 28.9%(11/38), HPV 16 and 18; 26.3%(10/38)), 2. HPV 16 was detected in 27(90,0%) of 30 males whose wives were positive for HPV 16. But HPV 18 was detected in only 3(27.3%) of 11 male consorts whose wives were positive for HPV 18. And HPV 1S was detected in all male consorts whose wives were positive for HPV 16. In addition, HPV 16 or 18 were positive in 3 of 7(42.9%) male consorts whose wives were negative for HPV 16 and 18. Conclusively, these results suggest that HPV might be transmitted by sexual contacts in heterosexual couples.

OBJECTIVES: As one of the possible mechanisms of viral evasion in the HPV-infected cervical cancer cells, the role of amino acid sequence change in epitope region has not been reported yet. In this study, sequence variations of HPV 16 E6, E7 gene, especially focused on epitope region, were analysed, the status of immunomodulatory factors were documented, and finally the possible correlation between the sequence variations and the loss of HLA class I expression was examined. METHODS: The entire ORF(open reading frame)s of HPV 16 E6, E7 were sequenced by the fluorescent dideoxy termination method. In addition proteins and transcripts of HLA-ABC, beta2-microglobulin(beta2-m), TAP (transporter associated with antigen processing), and LMP(large multi-functional proteasome) were evaluated by immunohistochemistry and RT-PCR, respectively in 40 clinical specimens of primary cervical cancer and 6 cervical cancer cell-lines. Medical records including pathologic reports were reviewed. RESULTS: Among the 27 cases confirmed as harboring HPV 16 DNA, only one(3.7%) found as a prototype. Among 11 kind of variants identified in total, 4 variants(5 nucleotide sites) which were never reported before has been found, registered firstly to GenBank. The most frequently found one(16 cases, 59.3%) contains D25E, N29S in E6, E7 region, respectively and the most common variation in E6, E7 ORFs found concurrently(p<0.05). Down-regulation of HLA-ABC and beta2-m was identified in 32(86.5%) and 35 cases(89.7%), respectively and transcripts of TAP, LMP were identified in over 85% of cases. However, there was no significant difference in HPV 16 infection, D25E in E6 and so on between HLA-ABC, beta2-m positive and negative groups. The well-known clinicopathologic parameters did not correlate with sequence variations and immunomodulatory factors. Five sequence variations in HPV 16 E6, E7 ORFs that were not previously reported worldwide were found, registered firstly to GenBank. CONCLUSION: It seems that multiple mechanisms are operated in down-regulation of HLA class I molecules and the phenotypic profile of immunomodulatory factors seems to be unrelated in vivo to the naturally occurring HPV 16 E6, E7 variations in epitope region.

No effective therapy has yet developed for liver fibrosis/cirrhosis by directly inhibiting the accumulation of extracellular matrix. This study was undertaken to determine the effect of tetrandrine in rat model of liver fibrosis induced by carborn tetrachloride (CCl4) administration intraorally. Tetrandrine, a calcium channel blocker, is anti-inflammatory constituent of the families Menispermaceae and Ranunculaceae, which have been used as folk remedies in China. Repeated administration of CCl4 for 14 weeks to rats induced liver fibrosis with steatosis. Rats were killed after 4, 8 or 14 weeks of treatment with CCl4, CCl4 tetrandrine (30 mg/kg) or CCl4 tetrandrine (50 mg/kg). The histopathological findings of liver were observed semi-quantitatively by light microscopy and volume percentage of the collagen deposition was determined by image analyzer. Tetrandrine inhibited collagen deposition induced by CCl4 administration, as shown by less severe steatosis and fibrosis and significantly decreased volume percentage of collagen fibers in CCl4 tetrandrine treated animals compared with CCl4 only group. Thus, the administration of tetrandrine holds great promise for treating subjects with liver fibrosis/cirrhosis as a result of chronic hepatic injury.

BACKGROUND: Extracorporeal shock wave therapy (ESWT) is one of the treatment options used for patients with myofascial pain syndrome (MPS), although its effectiveness is controversial. The purpose of this study was to evaluate the effectiveness of ESWT in the treatment of MPS in terms of pain relief and functional improvements. METHODS: We assessed 93 patients with MPS who underwent ESWT from March 2009 to July 2014. After exclusion of 25 patients with shoulder diseases, 68 patients were enrolled in the study. The mean follow-up period was 7.5 months (± 4.2 weeks), and the average duration of symptoms was 5 months (range, 2-16 months). ESWT was applied to intramuscular taut bands and referred pain areas once a week for 3 weeks. Visual analog scale (VAS) pain scores and American Shoulder and Elbow Surgeons (ASES) scores were obtained at an initial assessment and at the 6-week, 3-month, and 6-month follow-up assessments. RESULTS: VAS pain scores and ASES scores improved significantly after 3 sessions of ESWT (p<0.05). Both scores were improved, although not significantly, after 6 weeks (p>0.05). CONCLUSIONS: ESWT is an effective treatment option for patients with MPS.

Mitochondrial DNA (mt DNA) and the non-recombining region of the Y chromosome are passed down, unaltered, from generation to generation, matrilineally and patrilineally, respectively. Therefore, the Y-chromosome DNA and mtDNA are known as lineage markers, and they play important roles in studies based on human migration and evolutionary history. Y-chromosome DNA is used in forensic analysis to identify individuals involved in cases of sexual assault. In this paper, we review the methods of statistical evaluation of lineage markers used in forensic identification. We also review the combined approach of autosomal and lineage marker evidence.

BACKGROUND: A fully automated enzyme-immunoassay (EIA) analyzer, Enzymun System, ES-300 (Boehringer Mannheim, Germany) uses streptavidin technology and performs single test or panels of up to 12 tests per run. We evaluated the results of ES-300 for anti-HCV by comparing the results with microplate-EIA, radioimmunoassay (RIA), and confirmatory test. METHODS: Total 79 sera (51 positive, 24 negative, 4 indeterminate results confirmed by Lucky HCD Confirm) were analysed. ES-300 with Enzymun-Test(R) Anti-HCV (Boehringer Mannheim, Germany) and microplate-EIA (Green Cross Center Innotest HCV 3.0(R)) were used. Fifty one sera were examined additionally by 2nd-generation RIA method, NANBDINE 125C(General Biologicals Corp., R.O.C.). And all results were compared to the results of Lucky HCD Confirm. RESULTS: The overall concordance rate of ES-300 and Innotest(R) was 72/79 (91.1%). The results of Lucky HCD Confirm on seven discrepant samples were five negative and two indeterminate. The results of ES-300 and NANBDINE 125C showed concordance rate of 90.2%. The sensitivity and specificity of ES-300 with regard to Lucky HCD Confirm were 94.5%, and 87.5%, respectively, and that of Innotest(R) were 98.2% and 66.7%, respectively. Clear distinction of positive and negative results by signal/cut off ratio was available in both EIAs. The positive predictive values of ES-300 and Innotest(R) were 94.5%, and 87.1%, respectively. CONCLUSIONS: ES-300 showed relatively good results in sensitivity and positive predictive value with regard to confirmatory test. In EIA-positive persons, however, follow-up study would be necessary for reliable evaluation of HCV infection.

BACKGROUND: Glutaraldehyde is used most commonly as a high-level disinfectant for semicritical patient-care equipments. However, its potential toxicity to healthcare workers and a long exposure time needed to kill mycobacteria can be problematic. Recently, Perasafe(R) (Antec International, UK) has been introduced in the market as a safe and very effective disinfectant. This study was to evaluate the efficacy of Perasafe(R) against not only bacteria and yeast but also mycobacteria and bacterial spores and compare it with glutaraldehyde. MATERIAL AND METHOD: Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans, Mycobacterium tuberculosis, and Bacillus subtilis were used for the test. Perasafe(R) and Cidex(R) were used at the final concentration of 1.62% and 2.25%, respectively; the disinfectants were neutralized by Tween 80 (0.5%) in the mycobacterial test and by lecithin (0.75%) in all other tests. Bacterial suspensions were made in phosphate buffer with or without fetal bovine serum (1%) to simulate dirty or clean conditions, respectively. The disinfectants were tested at 0, 24 and 48 hr of preparation to check stability. An effective disinfectant activity was defined as a 5 log10 reduction in viable counts. RESULTS: E. coli, S. aureus, P. aeruginosa and C albicans were effectively disinfected in less than 5 min by both Perasafe(R) and Cidex(R) and the both disinfectants remained equally effective under the dirty conditions or at 48 hr of preparation. Perasafe(R) was effective in 1 min against B. subtilis spores compared to Cidex(R) which took 30 min for the same activity. M. tuberculosis was effectively disinfected in 10 min by Perasafe(R) and 20 min by Cidex(R). CONCLUSIONS: Perasafe(R) showed greater tuberculocidal and sporicidal activities than Cidex(R), although both disinfectants were equally effective against common bacterial and yeast pathogens. Perasafe(R) may be an outstanding high-level disinfectant for endoscopes and other semicritical medical equipment.

Cerbral embolism in the patient with rheumatic heart disease is a serious complication and has poor prognosis. In view of the abundance of rheumatic heart disease in Korea, a retrospective clinical study was done on 49 cases of cerebral embolism with rheumatic heart disease admitted to Severance Hospital from 1970 through 1977. The resultls were as follows; 1. The age distribution of the 49 patients ranged from 20 to 70 years and the mean age was 48.7 years. Twenty-five patients, more than half of the total number, were in their 5th and 6th decades, and the peak of the incidence was in the 6th decade. Male to female ratio was 1:1.3. 2. Mitral stenosis was by far the most predominant valvular lesion representing 33 of the 49 cases, and 25 of the 33 patients had "pure" mitral stenosis. Mitral valve involvement represented 43 of the 49 cases. 3. Seventeen of the total 49 cases were in regular sinus rhythm whereas 32 of the 49 were in atrial fibrillation at the time of admission. 4. Twenty-two of the 49 patients expired during the hospitalization whereas only six made complete recovery and the other 21 made variable degrees of recovery. The anticoagulant treatment did not appear to make any significant difference in the mortality probably due to inadequacy of timing, completeness and followup.

There are several methods for the reconstruction of partial urethral defect, including split-thickness skin graft, full-thickness skin graft, and preputial flap and free flap. Despite partial success using these methods, most results are unsatisfactory due to frequent complications such as postoperative infection, fistula formation, hair growth and stricture. There have been several pioneering experiments in this field using autogenous vein graft and the results have been controversial. However, the fact that the endothelial lining is replaced by natural urethral epithlium is generally accepted as a positive effect of this method. This experiment was designed to identify the possibility of using vein graft for the reconstruction of partial urethral defect. Two different types of vein graft method were performed in a total of 20 New Zealand White rabbits with partial urethral defect. Firth, for the patch-graft group, a 1 x 1 cm rectangular vein graft was sutured at a defective area of the same size. Second, for the tubed-graft group, a vein graft segment 1 cm long was replaced at a segmental urethral defect of the same length. Histologic study was performed at three and eight weeks postoperatively in each group. The process of transitional ell epithelial replacement within the grafted vein was uniformly observed in both experimental groups at three weeks postoperatively. At eight weeks postoperatively, the epithelial replacement was almost complete and histologically undistinguishable. In the retrograde urethrogram performed after 8 weeks, the urinary flow in the patch-graft group was normal and showed no stricture, and two of five rabbits in the tubed-graft group showed partial stricture at the graft site. In conclusion, natural urethral epithelium was restored in grafted venous segments irrespective of the type of graft. Partial stricture was observed in 40% of the tubed-graft group while complete reconstruction was possible in the patch-graft group.
