Electronic PCK 쇄석기를 이용한 요석환자의 치료경험
정태융,심희영 관동대학교 의과학연구소 2000 關東醫大學術誌 Vol.4 No.1
Purpose : To review the results of primary in situ extracorporeal shock wave lithotripsy(ESWL) far the treatment of urinary tract stones using a third-generation lithotriptor, the Electronic PCK. Materials and Methods : The study comprised a retrospective review of treatment outcome in 131 stones who were treated with primary in situ ESWL, assessing the success and complication of this approach. Results: 92% of cases were stone-free : 10 cases failed ESWL and 9 cases were treated by ureteroscopic stone extraction and 1 case by open pyelolithotomy with no complication, Stone-free rates were 91% far renal stones, 94% for upper ureteral stones, 83% for lower ureteral stones. Complication rates were 30% for renal stones, 37% for upper ureteral stones, 33% for lower ureteral stones. Conclusions : Primary in situ ESWL remains an effective form of treatment for urinary tract calculi, although stone-free rates are lower for larger stones.
복압성요실금(Stress urinary incontinence)과 절박성요실금(Urge incontinence)환자에서 TVT 수술 결과의 비교
이경구,이준호,권용욱,정태융,심희영,이상익 관동대학교 의과대학 의과학연구소 2005 關東醫大學術誌 Vol.9 No.1
Tension-free vaginal tape(TVT) has been widely used in the management of stress urinary incontinence(SUI), and has been applied to urge incontinence (UI). We evaluated and compared the outcomes between SUI and UI for patients who had undergone TVT. Patients were categorized into SUI(33 patients) and UI(26 patients). Before treatment, we asked about LUTSs using female bladder questionnaire. And we asked about sexual function. After treatment, the same questionnaires were repeated. During the postperative period, the objective and subjective success rate were evaluated. For operation outcome results, in SUI group there were 29 cases of cure (87.9%)and 2 of improvement(6.1%), and in UI group there were 20 cases of cure(76.9%)and 3 of improvement(11.5%) (p>0.05). The operation satisfaction rate of patients was 90.9% in SUI group and 84.6% in UI group(p>0.05). Improvement of sexual satisfaction occurred in 6(20.0%) of SUI group, and 3 (18.8%) of UI group, respectively(p>0.05). The objective success rate, satisfaction rate and sexual satisfaction of SUI patients did not significantly differ from the women with UI. Also, these results shows that TVT procedure improves some LUTSs in both groups. We consider the TVT procedure to be an effective treatment not for stress urinary incontinence but also urge incontinenece.
Intraspecific Variation of Cytochrome b Gene in Korean Frog , Rana amurensis
Lee, Hei Yung,Oh, Se Jo,Park, Ok Yi,Jin, Joung Hwa 한국유전학회 1996 Genes & Genomics Vol.18 No.4
A fragment(=350 base pair) of mtDNA at the cytochrome b gene site was amplified and sequenced to examine intraspecific variation of R. amurensis. The specific oligonucleotide primer set for polymerase chain reaction (PCR) was designed from a comparable published sequence of Xenopus leveis. Level of the partial cytochrome bgene sequence divergence was about 3% within species. The values were higher than those of another taxa, because certain regions of the sequence were identified as being particulaly differed. The results showed the those regions occur in 31-32 and 75, 78 (same numbering for the frog Xenopus laevis protein sequence). An interesting finding is that the regions showed variation within population. Therefore, these results suggest that the level of cytochrome b gene sequence divergence can be differed on the specific site. We have observed an example for the higher sequence divergence within species in partial cytochrome b gene.

The partial sequences, 243 base pairs, of the mitochondrial cytochrome b gene were analyzed to infer genetic relationships among the Rana nigromaculata populations from Korea and Japan. Six different haplotypes were detected from 5 populations. The pairwise sequence differences were ranged from 2 - 4 bp among 5 haplotypes of Korean populations, and 15 - 18 bp between Korean and Japanese (Kyoto) haplotypes. Based on Tamura-Nei distance, average percent sequence divergence among the Korean haplotypes and between Korean and Japanese (Kyoto) haplotypes were 1.1% (0.8% - 1.7%) and 7.4% (6.6% - 8.0%) respectively. Contrary to the results of isozyme analysis which revealed the low level of genetic divergence (Nei's genetic distance D<0.1) between Korean and Japanese populations, the genetic variation of mtDNA haplotypes appeared to be highly differentiated between these two populations. The incompatibility of the genetic divergence between isozyme and mtDNA variations was discussed.
노랑 초파리의 염색체에 존재하는 수컷 재조합 요소의 위치
Lee, Hei Yung,Lee, Kowan Ja 한국유전학회 1989 Genes & Genomics Vol.11 No.1
The frequencies of male recombination and site of the male recombination factor (MRF) were analysed with Song-nei strain of Drosophila melanogaster. The total frequency of male recombination was 0.076%. The frequency of male recombination in 2nd chromosome and 3rd chromosome were O.106% and 0.073% respectively. The sites of MRF were existed between b-c loci in 2nd chromosome and th-cu loci in 3rd chromosome. According to this result, MRF region was linked with heterochromatic region.
한국산 도롱뇽(Hynobius leechii)염색체의 인형부위(NORs)다양성에 관하여
이혜영,차선호 한국유전학회 1995 Genes & Genomics Vol.17 No.2
The chromosome constitutions of 106 individuals of Hynobius Ieechii collected from 17 localities in Korea were analyzed by Giemsa and Ag-NOR staining methods. The chromosome number of most of the individuals was 56 with AN number of 94. The size of NORs was homomorphic or heteromorphic pair at the tip of centromere of No. 23 chromosomes in 59 out of 106 individuals. The rest exhibited a high level of variation in number and site of NORs, but there was no intra-individual variation. All specimens from 4 (Hadong, Kurye, Chisan, Yangpyong) out of 17 populations had NORs on No. 23 chromosome, while many specimens from the rest of the populations had NORs variations with the rate of 44%. The mechanisms of NORs variation were explained by translocation and pericentric inversion of the parts of NORs, insertion of amplified 18S+28S rRNA gene segment and Ag-NOR staining effect that stain only real NORs in a species. Especially, all the specimens from Yangsan showed that the site of NORs was located at a little below the centromere on No. 23 chromosome, which caused by pericentric inversion.
노랑초파리의 GD STERILITY 에 관한 온도 및 AGE 의 영향에 관한 연구
이혜영,지관자 한국유전학회 1987 Genes & Genomics Vol.9 No.4
An experiment was carried out to investigate the influence of temperature and aging on GD sterility from reciprocal crosses with π_2strain and Canton-S strain of Drosophila melanogaster. It was found that the GD sterility traits were observed display a characteristic reciprocal cross effect by low egg production and strongly depend on female aging effect and sensitive in various temperature. It was concluded that the GD sterility was induced by high and narrow range of temperature 25℃-29℃ and age a female produced high egg production.
