Background : In recent years gonorrhoea has been panendemic and remains one of the most common Sexually Transmitted Diseases in the world, especially in developing countries. Objective & Method : For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria Gonorrhoeae(PPNG), Ive have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results : In 1994, 168 strains of N. gonorrhoeae were isolated, among which 109 (64,9% ) were PPNG. Conclustion : Our results suggests that the prevalence of PPNG in Seoul is still increasing.

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 clinical analysis was carried out with 182 cases of craniocerebral injuries under 15 years of age, admitted at the Department of Neurosurgery, Chung Nam National Universty Hospital during the period from September, 1990 to September 1993. Following results were obtained : 1) There were 133 males and 49 females and sex ratio was 2.7% 2) Age incidence of the accidents was greatest at 6 years of age and mostly distributed to the age group between 4 to 7. 3) Seasonal peak of the accidents was at May. 4) The accident occurred mostly botween 4 P.m. and 6 P.m in a day.5) The most frequent cause of the craniocerebral injuries was traffic accident(105cases, 57.69%) 6) No deterioration of cansciousness before and after the admission was doserved in 68cases(37.36%) 7) Pupillary change was observed in 25 cases and Babinski sign was elicitable in 31cases 8) Early convulsion and vomiting were frequent symptoms in childhood. 9) Skull fracture was observed in 72 cases(39.56%) in which linear fracture was most frequent and predilection site was parietal bone. 10) The accompanying rate of skull fracture in intracranial hemorrhage was 65.54% 11) Associated injures were found in 44 cases(24.18%). The frequent ones were e xtremity fracture, clavicle fracture 12) The overall mortality was 7.14%.

Objective: In 1960`s Bonghan Kim`s team found BongHan(BH) ducts which were presumed as acupuncture meridians and BH corpuscles. They asserted Bonghan theory and SanAl theory which was involved in cell division and cell restoration. However, many other experiments which had been operated to demonstrate and find the existence of BH ducts had failed because of the secret of blue stain drugs. During the last several years, BongHan theory has been revived through experimental researches to find the anatomical structures of BH ducts and corpuscles by Soh`s Biomedical Physics Lab. Soh`s research team used the staining with Janus Green B, Alcian blue, nanoparticles and Acridine Orange. We used DAPI staining to find the existence of BH ducts and the corpuscles and to observe nuclear arrangement. Methods: We used japan white rabbits as experimental animals. BH ducts and corpuscles were stained with DAPI. The nucleus configuration in BH ducts stained with DAPI were observed with microscope. Results: In this study, we found thread like structures in silver white color distinguished from the blood vessels, nerves and lymph vessels. These thread like vessels in the linear duct shape were connected to same colored mass in the ball shape. Thread like structures we found could be separated easily from the surrounding other organ mass. The nuclei of the thread like structure in DAPI staining, are about 10~20㎛ length, in rod shape and linear arrangement. Conclusion: We concluded that the thread like structure we found was same vessel reported by Soh`s research team, BongHan ducts and corpuscle.

The metachromatic behavior of methylene blue (MB) ia aqueous solution and in the presense of sodium dodecyl sulfate (SDS) have been studied by the absorption spectroscopic method. The results are as follows. The association force of the MB molecules in aqueous solution seems to be complex of three factors, i.e., London's dispersion force, the hydrophobic interaction and the interaction between permanent dipoles it has been measured of critical micelle concentration (CMC) in aqueous solution of SDS and that of MB-SDS to be 8.0mM and 7.9mM respectively. This indifference between CMC values of the pure SDS and MB-SDS system would mean the formation of dye-rich induced micelles(drim). The spectral changes of MB-SDS system with the addition of the inorganic salts have been observed. The addition of the salt into the solution causes the redistribution of MB molecules in the complex(D_n^+ S_m^-). It would be resulted from the decrease of the stacking effect between the bound MB molecules. The spectral changes observed in the MB-SDS system with the increase of the S/D values are analyzed and the behavior of the meta band is explainsd in terms of the stacking theory and micelle formation theory

목적: hNIS는 갑상선 조직 외에 다른 조직들에서도 발현된다고 알려져 있다. 유방암 세포는 그런 조직들 중에 하나이며, 그에 의한 유방암의 방사성옥소치료의 가능성이 제시되고 있다. 본 연구에서는 유방암 조직에서 hNIS의 발현정도를 알아보고, ^99mTc-MIBI 유방스캔과 hNIS의 발현 정도와의 관계를 조사하여 보았다. 대상 및 방법: 본 연구에서는 유방암으로 수술을 시행했던 56명의 환자를 대상으로 하였다. hNIS의 발현은 면역조직화학염색에 의해서 평가되었으며, 그 결과를 ^99mTc-MIBI 유방스캔의 판정 결과와 비교하였다. 결과: 전체 56명의 환자에서 hNIS의 발현율은 41.1%였다. 병리학적 진단에 의해 침윤성관상피암종이었던 49명에서의 발현율은 42.9%, 관상피내암종이었던 7명에서의 발현율은 28.6%였다. ^99mTc-MIBI 유방스캔에서 국소섭취 소견이 관찰되었던 41명에서의 hNIS의 발현율은 31.7%였다. 비정상적인 섭취 소견이 관찰되지 않았던 15명의 환자에서의 hNIS의 발현율이 의미있게 높게 관찰되었다(66.7%, p>0.05). 결론: 유방암 환자에서의 hNIS의 발현율은 그다지 높지 않았다. ^99mTc-MIBI 유방스캔에서 섭취증가 소견이 없을 때 hNIS의 발현율이 더 높았다. Purpose: Human Na^+/I- symporter (hNIS) is known to be expressed in many tissues other than thyroid gland. The breast cancer cells are one of them and the possibility of radioiodine therapy in treatment of the breast cancer may be suggested. We investigated the expression rate of hNIS and the relationship between the expression of hNIS and the finding of 99mTc-MIBI scintimammography in the breast cancer. Materials and Methods: Surgically proved 56 patients with breast cancer were the subjects of this study. The expression of hNIS were evaluated by immunohistochemistry and the results were compared to the findings of 99mTc-MIBI scintimammography. Results: Overall expression rate of hNIS was 41.1% in 56 patients. According to the pathologic diagnosis, it was 42.9% in 49 patients with invasive ductal carcinoma and 28.6% in the 7 patients with ductal carcinoma in situ. The expression rate of hNIS in the 41 cases with a focal increased uptake at he breast lesion on 99mTc-MIBI scintimammogram was 31.7%. That in the 15 cases without any abnormal uptake on the scan was significantly higher(66.7%, p<0.05). Conclusion: The expression rate of hNIS in the patients with breast cancer was not so high. The rate was higher in the patients with no increased uptake at the breast lesion on 99mTc-MIBI scintimammography. (Korean J Nucl Med 2002;36;325-32)

We performed costochondral grafting in mmandibular reconstruction including condyle replacement in 5 patients which have 4 cases of ameloblastoma, 1 case of resorption of left condyle due to osteomyelitis. We harvested the 6 th costochondral cartilage of unaffected side. No specific complications were appeared with unexpected fracture of costochondral junction and infection of operation site, These patients show 30-45mm at month opening, near normal of affected side, near normal or normal of unaffected side at lateral excursion. Postoperative coureses was uneventful with improved cosmetic and functional results. Our report is indicated that the costochondral graft is satisfactory to reconstruct mandibular defect including condyle replacement, especially in growing patients.

The combustion process of diesel engine is very complex because there are many factors which have effects on it. The study on these factors is necessary in order to improve diesel combustion. So, the effects of intake air temperature, cavity geometry and fuel injection timing on combustion characteristics were investigated in this paper with the visualized diesel engine. When the intake air temperature was increased, it was proved that the point of ignition nuclei was fasten in plate type combustion chamber. Also, it was turned out that the most effective fuel injection timing in engine power was BTDC 22° CA.
