Background: In most solid tumors, the CD34 antigen has not been detected, so positive selection of CD34+ cells may reduce tumor cell contamination and the CD34+ cells are capable of reconstituting hematopoiesis. We tried CD34+ cell transplantation in two patients. Method: CD34+ cells from chemotherapy + G-CSF mobilized PBPCs or bone marrow were positively selected with an avidin-biotin immunoadsorption column (CEPRATE SC system). Case 1. One course of chemotherapy using cyclophosphamide(200㎎/㎡) and etoposide (4.2g/㎡), combined with G-CSF(5㎍/㎏) S.C. was used in a relapsed lymphoma patient. This patient responded to the induction chemotherapy. CD34+ cells from harvested bone marrow were selected by the CellPro immunoadsorption column. The total number of mononuclear cells loaded onto the CellPro was 2.4×10^(8)/㎏, with 1.1% CD34+ cells. After column separation, the total number of positively selected cells was 5.16×10^(6)/㎏. The number of CFU-GM was 76.8×10⁴/㎏. This patient was treated with melphalan (140㎎/㎡) and TBI (1200cGy) and the positively selected CD34+ cells were infused. The time to neutrophil recovery greater than 0.5×10^(9)/L was 19 days and the time to platelet recovery greater than 50×10^(9)/L was 21 days. Case 2. Two courses of mobilizing chemotherapy were given 4 weeks apart using taxol(210㎎/m2) and adriamycin(60㎎/m2), combined with G-CSF(5㎍/㎏) S.C. in a breast cancer patients with 7 axillary node metastasis. CD34+ cells from each single leukapheresis product were selected by the CellPro immunoadsorption column. In the first collection, the total number of nucleated cells was 4.4×10^(8)/kg, with 0.42% CD34+ cells. In the second collection, the total number of nucleated cell was 2.8× 10^(8)/㎏ with 0.43% CD34+ cells. After colum separation, the total numbers of collected cells were 4.0×106/kg and 4.8×10^(6)/kg, the total number of CD34+ cells were 1.2×10^(6)/㎏ and 0.82×10^(6)/㎏. Colonogenic assays of positively selected CD34+ cells gave rise to myeloid erythroid, and multilineage colonies, with a median of 190 CFU-GM, 190 BFU-E, and 164 CFU-GEMM per 1×10³ adsorbed cells, respectively. High-dose chemotherapy with cumulative doses of 40mg/㎡ mitoxantrone, 750mg/㎡ thioptepa, and 1000mg/㎡ carboplatin was administered. Positively selected CD34+ cells were rapidly infused 24 hours after the end of high-dose chemotherapy. The time to neutrophil recovery greater than 0.5×10^(9)/L was 16 days and the time to platelet recovery greater than 50×10^(9)/L was 20 days.

Kim, Si-Hyung,Choi, In-Sun,Cho, Jin-Hwa,Park, Eun-Ju,Jang, Il-Sung,Choi, Byung-Ju,Kim, Hyun-Jung,Kim, Young-Jin,Nam, Soon-Hyeun The Korean Academy of Oral Biology 2006 International Journal of Oral Biology Vol.31 No.2

Dysplasia-associated seizure disorders are markedly resistant to pharmacological intervention. Relatively little research has been conducted studying the effects of antiepileptic drugs(AEDs) on seizure activity in a rat model of dysplasia. We have used rats exposed to methylazoxymethanol acetate(MAM) in utero, an animal model featuring nodular heterotopia, to investigate the effects of AEDs in the dysplastic brain. Pilocarpine was used to induce acute seizure in MAM-exposed and age-matched vehicle-injucted control animals. Field potential recordings were used to monitor amplitude and numbers population spikes, and paired pulse inhibition in response to stimulation of commissural pathway. Two commonly used AEDs were tested: diazepam 5, 2.5mg/kg;phenytoin 40, 60mg/kg. Diazepam(DZP) and phenytoin(PHT) reduced the amplitude of population spike in control and MAM-exposed rats. However, the amplitude of population spike was nearly eliminated in control rats as compared to the MAM-exposed rats. Pharmaco-resistance was tested by measuring seizure latencies in awake rats after pilocarpine administration(320mg/kg, i.p.) with and without pretreatment with AEDs. Pre-treatment with PHT 60 mg prolonged seizure latency in control rats, but not in MAM-exposed animals. The main findings of this study are that acute seizures initiated in MAM-exposed rats are relatively resistant to standard AEDs assessed in vivo. These data suggest that animal model with cortical dysplasia can be used to screen the effects of potential AEDs.

이성수,김남수,김진호,김용배,황보영,김화성,안규동,이병국 大韓産業醫學會 2005 대한직업환경의학회지 Vol.17 No.4

Objectives: This study was conducted with new workers who entered lead industries from 1992 to 2001 to evaluate the genetic susceptibility of ALAD (δ-aminolevulinic acid dehydratase) and VDR (vitamin D receptor) gene on health effect of lead exposure. Methods: Among the subjects of the database of lead industries at the Soonchunhyang University Institute of Industrial Medicine, only new workers were selected for this study. The total of eligible workers for this category was 3,540 workers, including non lead exposed workers of same lead industries. From stored blood in specimen bank of Soonchunhyang University, genotype of ALAD and VDR were measured using PCR method. Variables for this study were blood lead as an index of lead exposure, ZPP (zinc protoporphyrin in blood), urine ALA (δ-aminolevulinic acid), and hemoglobin as an index of hematopoietic effect of lead. Information on sex, job duration, and weight were collected for personal information. The data were analyzed using SAS (version 8.2) with descriptive analysis of t-test and multiple regression analysis. Results: Among 3,540 new employed study subjects during period of 1992-2001, 3,204 workers (90.5%) had ALAD genotype 1-1, while 336 workers (9.5%) had variant type of ALAD (1-2 or 2-2). For VDR genotype, 2,903 workers (89.7%) out of total tested 3,238 workers were belonged to type bb and 335 workers (10.5%) were type bB or BB. The distribution of genotype of ALAD and VDR were not different according to the job duration in male workers, but were different in female workers. The effect of ALAD and VDR genotype on blood lead were positively significant in the analysis of all cumulative data of new employed workers for 10 years. The effect of VDR genotype on blood lead were stronger than that of ALAD While the variant ALAD gene made decrease of mean ZPP and ALA in urine after controlling for blood lead and other covariate, the variant VDR gene made increased the mean ZPP and ALA in urine in all cumulative data analysis and cross sectional analysis by job duration. For hemoglobin, ALAD and VDR genotype did not affect the mean value. Conclusions: From the above our results, we found that ALAD and VDR genotype exerted significant effect in various way. We confirmed that the finding of a cross sectional study of protective effect of variant ALAD on the effect blood lead on blood ZPP in our retrospective study design. It was found that VDR did not exert protective effect for lead exposure as the variant ALAD did.

이성수,김진호,김남수,김화성,안규동,이병국 大韓産業醫學會 2004 대한직업환경의학회지 Vol.16 No.2

목적 : δ-aminolevulinic acid dehydratase (ALAD)는 다형질성 (polymorphism)의 특성이 있어 유전형질에 따라 남의 인체영향이 다르다고 보고 된 바 있다. 본 연구에서는 이 유전인자의 다형질성이 신기능 지표들에 미치는 영향을 알아보고자 하였다. 방법 : 조사대상으로는 납 취급 사업장에서 납 작업에 종사하는 935명의 남자 근로자들과 동일한 사업장에서 근무하는 비 납 작업자 87명을 선정하였다. 단면적 신기능지표로는 BUN, 혈청 creatinine, 혈청 uric acid, 요중 총단백을 측정하였으며, 납 폭로 지표로는 혈중 납량을 측정하였다. 또한 개인 일반 변수로서 체중, 연령, 직력과 흡연 및 음주습관을 조사하였다. 결과 : 납 작업자 군의 혈중 납의 평균(표준편차)은 25.4±10.9 ㎍/㎗이었으며, 비 납 작업자 군의 평균(표준편차)은 10.1±2.8 ㎍/㎗로서 양 군 간에 유의한 차이가 있었다(p<0.05). 납 작업자 군에서 이형유전형질인 ALAD2 유전자형을 가진 납 작업자는 99명으로 전체의 10.6%를 차지한 반면, 비 납 작업자 군에서는 ALAD2를 가진 근로자는 4명으로 전체의 4.6%이었으며 양 군 간의 유의한 차이는 없었다. 동형유전형질인 ALAD1 유전자형 군의 혈중 납의 평균(표준편차)은 23.9±11.4 ㎍/㎗ 이었고 ALAD2 유전자형 군의 평균(표준편차)은 25.8±10.7 ㎍/㎗이었으나 양 군 간에 유의한 차이는 없었다. 신기능 지표들인 BUN, 혈청 creatinine, 혈청 uric acid 및 요중 총단백의 평균은 납 작업자 군이나 비 납 작업자 군에서 유의한 차이가 없었으며, 유전형질구분에 따른 차이도 없었다. 연령, 직력, 체중, 음주여부, 흡연여부 및 혈중 납을 통제한 후 BUN의 중위수를 기준으로 중위수이상 유무를 종속변수로 하고 관련변수들을 통제한 후 실시한 logistic 분석에서는 ALAD2 유전자형의 odds ratio가 0.59 (95% 신뢰구간 : 0.38-0.91)이어서 ALAD2 유전자형 군에서 ALAD1 유전자형군보다 41% 적게 중위수를 가질 것으로 판명되었다. 혈청 creatinine의 중위수를 기준으로 중위수이상 유무를 종속변수로 하고 관련변수들을 통제한 후 실시한 logistic 분석에서는 ALAD2 유전자형의 odds ratio가 0.64 (95% 신뢰구간 : 0.40-0.98)이어서 ALAD2 유전자형 군에서 ALAD1 유전자형 군보다 36%가 적게 중위수를 가질 것으로 판명되었다. 결론 : 이상의 결과로 미루어 ALAD2 유전자형이 ALAD1 유전자형보다 납에 의한 체내대사에서 보호효과가 있을 것으로 추정된다. Objecthe: 6-Arninolevulinic acid dehydratase (ALAD) is a polymorphic enzyme that has two alleles, KAD1 (ALADl-1 as genotype) and M A D 2 (ALADI-2 or ALAD2-2 as genotype). AL.lhD genotype has been reported to mod@ the phmacokjnetics and toxicity of lead. The authors investigated the ionuence of ALAD genotype polymorphism on renal function in lead workers Methods: We studied 935 male lead workers and 87 male non-lead workers in the same industries. For cross-sectional renal indices, blood urea nitrogen (BUN), serum creatinine, semm uric acid and urine total protein were selected. Blood lead level was also measured an index of lead exposure. Information on weight, age, job duration, and smoking and drinking habits was collected. Results: Whereas the mean blood lead level of lead workers was 25.4f 10.9 PgldL, that of non-lead workers in the same premise was 10.1 f2.8 PgIdL, and the maence between the two groups was statistically signifcant. Whereas the prevalence of the variant allele, &AD2 in 935 lead workers was 10.6%, that in 87 non-lead workers was 4.4%. However there was no d~erence of prevalence between the two groups. The mean blood lead level of subjects with ALlhDl was 23.9f 11.4 Pg/dL, which was slightly lower than that of subjects with ALAD2 (25.8+ 10.7 pgldL). However, this differace was not statistically sigikficant. After adjustment for the covariates, the subjects with ALAD2 dele were 12.8% less &ely to have a median value or more of BUN than subject with ALAD1. Tihe adjusted odds ratio was 0.59 (95% confidence intervat 0.38-0.91). After adjustment for the covarjates, the subjects with ALAD2 allele were 9.3% less Wtely to have a median value or more of serum creatinine than subject with ALADl . The adjusted odds ratio was 0.64 (95% confidence interval; 0.41-0.98). Conclusions: From the above results, it was found that the variant allele, L A D 2 appeared to modify the association of lead and renal function, and that ALAD2 genotype may be supportive for the protective effect of lead.

( Jin Hwa Lee ),( Ga Won Yim ),( Eun Ji Nam ),( Sung Hoon Kim ),( Young Tae Kim ),( Sang Wun Kim ) 대한산부인과학회 2014 대한산부인과학회 학술대회 Vol.100 No.-

목적: Demonstrate a new instrument, technique or procedure 방법: In this video, we showed how to remove huge ovarian tumors in sinlgel port laparoscopic surgery by SW KIM`s method. SW KIM`s method is the technique to put a huge ovarian tumor into a specially designed extremely large endopouch (XXXL: 30x30㎠sized) using two conventional laparoscopic needle holders and one laparoscopic grasper and gravity by changing the patient`s position. After identifying the infundibulopelvic and uteroovarian ligaments salpingooophorectomy including huge ovarian tumor was performed by LigaSure. And then ovarian tumor was located in the pelvic cavity by changing the patient`s position into reverse-trendelenberg position and a XXXL endopouch was inserted and un-rolled inside the abdominal cavity. To insert a huge tumor into the XXXL endopouch, the endopouch was opened in triangular shape. Bilateral apex of baseline of trianglular opening of the endopouch was hold by two needle holders and then the upper apex was hold by a grasper. After holding three point of endopouch opeing, the patient`s position was changed into deep trendelenberg postion, then the tumor came into the endopouch by gravity. While changing the patient`s position, 2 needle holders and a graspers were moved into the pelvic cavity from the abdominal cavity. Aftere identifying the tumor inside the endopouch, tumors could be removed through the single port opening site or transvaginally in laparoscopic hysterectomy case without spillage of ovarian tumor. 결과: The advantage of SW KIM`s method is to remove ovarian tumor without spillage in a single port laparoscopic surgery by putting it into the large endoscopic bag despite narrow space. 결론: Using a specially designed 30×30 cm sized XXXL Endopouch and SW Kim`s technique, huge ovarian tumors could be removed without spillage in single port laparoscopic surgery.

本 實驗은 施設園藝地帶인 光山郡, 順天市, 康津郡 等에서 葉菜類와 果菜類의 育苗用 床土를 試料로 22点 分讓받아 수행하였으며 結果는 다음과 같다. 1.床土의 助成과 性質에 關與하는 가장 重要한 因子는 有機物含量인데 有機物含量이 높아짐에 따라 假比重과 眞比重은 낮았고 空隙率, 水分含量, 全窒素, 置換容量은 높아진다. 2. 葉菜類의 床土는 有機物含量이 많은 반면 果菜類床土의 경우는 그보다 낮게 나타났다. 봄결구배추床土의 有機物含量은 8.85~9.19%의 範圍로 別變化가 없었다. 3. 床土의 pH는 4.9~7.2의 範圍에 있었으며 大部分이 pH 7±1로서 中性에 가까웠다. 4. 置換性 K는 7点이 1.0m.e. 以上이었고 15点이 1.0m.e. 以下로 나타났다. 5. 苗의 바람직한 生育을 위해 P.K.의 量을 規定짓기는 어려우나 床土의 試料內에는 相當量의 養分이 含有되 있는 것을 알 수 있다. This experiment was intended to know the effects of physical and chemical properties of the excellent composts. Twenty two samples were collected from plastic covered greenhouse zone in chonnam province. The results obtained are as follows; 1. One of the most important factors in relation to the texture and other properties of the composts was the organic matter content. The higher the organic matter content were the lower the specific gravity and the apparent specific gravity and the higher the porosity, moisture content, total nitrogen and exchangeable capacity. 2. The composts for raising leaf vegetable seedlings contained higher levels of organic matter while the ones for fruit vegetable contained rather less. The organic matter contents in the composts for spring heading Chinese cabbage were not variable ranging from 8.85 to 9.19 percent. 3. Hydrogen-ion concentrations of the composts were in the range of pH 4.9~7.2 but most of them were in pH 7±1 or nearly neutral in their reaction. 4. Seven samples contained more than l.0m.e. of exchangeable potassium, and fifteen of them contained lower than l.0m.e. of it. 5. It was not clear how high of P or K levels were sufficient for the excellents in some of the samples, at least, were so high, that they seemed to contain surplus amounts of fertilizers.
