In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

The aim of study was to investigate genetic diversity for the calpain/calpastatin gene in three Hanwoo breeds [(Brown (n=62), Brindle (n=81) and Jeju Black (n=30)]. Random samples from three breeds of Hanwoo were selected and genotyped for the 7 SNPs of calpain/calpastatin using TaqMan method. Allele frequencies were investigated for CAPN1/CAST gene. Allele frequency of CAST2 SNP was 0.75, 0.59 and 0.22 for Brown, Brindle and Jeju black, respectively. The CAST3 revealed allele frequency of 0.59 and 0.57 in Brown and Jeju Black, while it showed very low allele frequency (0.07) in Brindle. In particular, favorable allele (G allele) for the CAPN1-2 SNP which was shown a strong association with tenderness in Taurine and Indicine cattle revealed 16% and 17% higher allele frequency in Brown Hanwoo (0.82) comparing Brindle (0.66) and Jeju Black Hanwoo (0.65). AMOVA demonstrated that among population variance occupied only 10% of total variance and among individual variance was 0%, while within individual variance was 90% of total variance. This result showed that population effect contributed very small portion of genetic to these three Hanwoo breeds, while within individual variance contributed large portion of genetic diversity within these Hanwoo breeds. In conclusion, three Hanwoo breeds (Brown, Brindle and Jeju black) showed a genetically homogeneous based on the 7 SNPs of CAPN1/CAST gene and it came from same ancestor to form modern Hanwoo breed.

Background/Aims: Retroperitoneal fibrosis is a fibrosing disease process which frequently develops ureteral obstruction. Malignant retroperitoneal fibrosis has been reported that various types of cancer including cancer of the breast, stomach, prostate, lung, cervix, uteri, colon, pancreas, ovary, and even Hodgkin's disease. While the pathogenesis remains obscure, small foci of metastatic neoplasm in the retroperitoneal space can elicit a desmoplastic reaction in secondary form to malignancy. Methods: Recently we experienced 7 cases of retroperitoneal fibrosis with advanced gastric cancer. So, we report 7 cases of retroperitoneal fibrosis with clinical and radiologic characteristics. Results: The most common signs and symptoms were related irreversible renal dysfunction. The urologic finding noted medial deviation of the involved ureters and hydronephrosis Conclusions: Clinical manifestations are abdominal pain, back pain, hydronephrosis, and uremia. When sudden back pain and hydronephrosis develop in advanced malignancy, physicians should be considerd for retroperitoneal fibrosis.

유구치의 깊은 우식은 치수병소을 유발하고 이를 조기에 치료하지 않을 경우에는 치수강저의 수많은 부근관을 통하여 치근분지부 병소로 이어진다. 지금까지 대부분의 교과서나 문헌에서는 이와 같은 경우를 발치의 적응증으로 기술하여 왔고 임상에서도 상례적으로 발치를 흔히 시행하였다. 그러나 유구치의 조기 상실은 수많은 부작용을 낳는 것이 필연적이다. 어린이의 골재생 능력이 우수하며, 치수강저와 치근분지부를 잇는 많은 부근관이 있음을 생각해 볼 때 유구치 치수 내의 감염원을 치수절제술로 제거하고, 이미 발생한 치근분지부 병소에 대해서는 소파술을 시행한다면 치근분지부 골조직의 신속한 재생이 가능하지 않을까하는 의문이 제기되었다. 본 중례는 3~6세 어린이에서 유구치 치근분지부 방사선 투과상이 2~4mm 정도의 깊이를 보이는 비교적 경미한 수준이면서, 연조직 누공을 보이는 10개 중례를 선별하여 치수절제술과 치근분지부 소파술을 시행한 결과, 모두에서 방사선적으로 골재생이 관찰되었다. 이를 통하여 유구치 치근분지부 병소나 누공을 보이는 모든 경우가 발치의 적응증은 아니며, 이 방법이 치근분지부 병소를 가진 유구치를 잔존시킬 수 있는 하나의 대안이 될 수 있음을 알 수 있었다. 그러나 이 방법이 객관적인 타당성을 얻기 위해서는, 병소의 크기와 진행정도, 계승 영구치의 성숙도, 환아의 연령 등 적응증에 대한 보다 심층적인 검토와 연구가 필요할 것으로 사료되었다. Deep caries in primary molars without early intervention frequently induce a pulpal disease and consequent furcation lesion with fistulous openings. Up to now, majority of the textbooks on pediatric dentistry and literatures have described that extraction of the inflicted teeth is indicated for these cases and in reality these teeth have usually been extracted in the dental clinics. However, when we recognize the excellent capacity of bone regeneration in children and the presence of numerous accessory canals at furcation areas, the removal of infection source in pulp by pulpectomy and inflammatory granulation tissues at furcation areas by furcal curettage might open the possibility of rapid healing at the furcation region. In this report. 10 cases of primary molars in 3 to 6-year-old children with fistulous openings and furcation lesions in moderate size of 2 to 4mm in depth radiolucency at furcation lesion have been chosen. After pulpectomy and furcal curettage, evident bone regeneration was detected rediographically in all cases. Through the cases, we came to realize that all the cases previously described are not the indications of extraction and this approach could make many cases with pulp and furca combined lesions survive and remain healthy in the children's dental arches. However, in order for this approach to acquire objective appropriateness. it is thought that more scrupulous evaluation is desirable on the various factors regarding the indication such as the extent of furcation, absorption status of teeth, amount of covering bone on succeeding teeth and so on.

The effect of corrosion products of hot-dip Al-Cr steel sheet on the corrosion resistance were investigated. The results of XRD and XPS measurements showed that there was not found a hydroxide type corrosion product on the surface of aluminized steel after salt spray test(SST) but there was found some cracks in the surface layer which accelerates corrosion during SST. In Al-Cr coated steel case, the main phase of the corrosion products after salt spray test was found to be Al(OH)₃. The polalization curves of aluminized steel after SST shows that there was no passivation layer. For the Al coated layer, a porosity in the Al-oxide film on the surface layer leads to preferential corrosion. After the Al coated layer was completely removed, the Al_(5)Fe₂layer was selectively corroded and then, the steel substrate was exposed to the electrolyte. However, the polalization curves of Al-Cr coated steel after SST shows that the passivation layer was formed, which could increase the corrosion resistance of Al-Cr coated steel. In case of the Al-Cr coated layer, the densely covered hydroxide layer of Al(OH)₃and the intermetallic compound layer of Al_(13)Cr₂became a barrier against further corrosion after the Al layer was removed. In this case, corrosion was not proceeded even through the same current density. The densely covered hydroxide of Al(OH)₃and the intermetallic compound layer of Al_(13)Cr₂were considered to be one of the reasons of high corrosion resistance for Al-Cr coating.

Microstructure and texture changes of aluminized coatings on steel sheets having Cr ranging from 0.0% to 1.0% in the coated layer were investigated. The surface morphology of the Al-Cr coated steel is not influenced by the increase of Cr contents in the coated layer. While the coated layer of aluminized steel consisted of two phases of Al and Al_(5)Fe₂, the aluminized coating layer containing Cr was composed of three phases of Al, Al_(13)Cr₂, and Al_(13)Fe₄+Al_(5)Fe₂. The surface layer was Al, the middle layer was Al_(13)Cr₂, and the interfacial layer between the coating and the steel substrate was Al_(13)Fe₄and Al_(5)Fe₂. The texture of the aluminized coating without Cr was characterized as a {001} fiber texture which major orientation was {001}<110>. As the Cr content in the aluminized layer was increased to 1.0%, the texture of the aluminized coating was not changed but the intensity of the {001} fiber texture was increased. The major orientation in the {001} fiber texture was changed from the rotated cube orientation of the aluminized coating with 0.1%Cr to the cube orientation of the aluminized coating with 1.0%Cr.
